[DUG] Produce PDF from text file
Using D2007 and Rave reports - should be easy to produce a PDF version of a text file report. The reports need to be printed using a non-proportional font, which is why I would like to use PDF rather than Notepad (which is often set to display in proportional fonts and users do not know how to change it). Anyone have sample code/examples?

Re: [DUG] Email/SMTP code
Have code working now nicely, email me if anyone wants what I am using. Is there a way to find the default settings from Outlook or Registry for: 1 - smtp setting 2 - users email address (for the From: address) At present I have to ask the users for this, should ideally be set from default email program settings.

Re: [DUG] Email/SMTP code
FYI Your original version had a small error in it that you fixed in the later
version you posted – at the IdMessage.free line – which I should already been
free’d by the previous SMTP.free, ie the IdMessage.free was not needed

Anyone got a recommendation for the best (free) code/samples to drive Indy10
for sending an email with attachment
-Indy10.2.3
-Send attachment
-SMTP server and email addresses will be known
I have tried a couple (eg AtoZed SendMail example) but it seems to time out

Re: [DUG] Email/SMTP code
Trying to debug this SMTP program, having tweaked the code a little – I am getting “Connection timed out” However I cannot debug, as on Windows 7 this program requires admin access. I restarted the IDE (BDS.EXE) running as administrator but still get the error message “Cannot create process” (Debug) or “Access denied” (Run without debugger). Can run the program outside of the IDE by right clicking and selecting “Run as administrator” but there is no debugging then! What have I missed?

Re: [DUG] Email/SMTP code
FYI - Removed a not needed SMTP component from the test project and restarted
the PC – I think it was the latter, that somehow Windows 7 remembered something
about the project/exe and still put UAC on it. Then debugger worked without

Re: [DUG] Email/SMTP code
Looks good.
Couple of quick questions:
Is this Indy10? (Indy is notorious for changing properties/names etc between
versions)
Is Asettings a TidSMTP component? haven’t figured out yet...
Do you have a copy of the uses clause just in case – I think I have it sorted
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, IdBaseComponent, IdComponent,
IdTCPConnection, IdTCPClient, IdExplicitTLSClientServerBase,
IdMessageClient, IdSMTPBase, IdSMTP, IdMessage, IdAttachmentFile;

Re: [DUG] Variable in String
Jolyon I imagine you have an opinion on doing this your way rather than like
this example below – I would be interested in hearing your reasoning.
A similar example – this is the sort of code I have been using
setlength(temp, 100); //has to be big enough first
setlength(temp, getEnvironmentVariable(PChar('USERNAME'), PChar(temp),
length(temp)));

Sorry Bob, I meant to include an example of your code tweaked to use “raw” a
char array with the Windows API routine. Here it is (this version displays
results rather than storing in a variable, but you get the idea J ) :
var
dir: array of Char;
s: String;
begin
s := ‘’;
SetLength(dir, MAX_PATH + 1);
if Succeeded(SHGetFolderPath(0, CSIDL_Program_Files, 0, 0, @dir[0])) then
s := PChar(dir);
ShowMessageFmt(s + ' (%d chars)', [Length(s)]);
// Outcome: s has both the right length *and* is null terminated correctly

Here is the code for doing that.

Don’t quote FW_Path element of the program path – you need to quote the entire
path AND program file name when/if any part of the path or the filename itself
does – or may – contain spaces:
e.g. “path a\sub a\sub b\prog.exe”
not “path a”\sub\prog.exe
So in your case, this should do the trick:
FW_Path := X;
DXF := openDialog1.FileName;
ProgramName := ‘”’ + FW_Path + '\FWTools2.4.7\bin\ogr2ogr” -f PostgreSQL
PG:host=192 user=postgres dbname=E5R password= '+ DXF +'

Subject: [DUG] Variable in String
Hi
I’m having trouble with using a variable in a string path.
When I use the variable FW_Path := ‘C:\Program Files (x86)’ with two single
quotes, the following works well and ShowMessage(ProgramName); displayed the
full path .
When I reference FW_Path to a variable X I get an error returned “Can Not
run” The variable X is returned as C:\Program Files (x86) without quotes.
I attempted Quote String and got the following ‘C:\Program Files (x86) with one
single quote.
Both cases return the same error - and in both cases ShowMessage(ProgramName);
displayed none of the path after C:\Program Files (x86).
Help would be appreciated.

Re: [DUG] FW: Web development
I am mystified why any government organisations would be stuck on IE6 given its the best door for any hacker wanting to intrude into a system. Its how Google was penetrated 18 months ago - hackers found workstations that had to use IE6 for historical reasons (reasons that were not all that good) I was astonished about 3 years ago to see an unnamed government department workstation using a pre-release version of Firefox, ie it was so old it was basically the old Netscape - with diagonal arrow buttons and all, probably something like v0.5 and from probably 2003. Surely any government IT department should not be relying on such old unpatched software if even to cover their own backsides when the inevitable problem occurs - its not a budget issue if free secure browsers abound. If they have to use IE6 for intranets, do they prevent IE6 from accessing the outside internet? And why can they not use later browsers for Intranets?

Re: [DUG] FW: Web development
I am an outside observer of Web development as I don't personally do it either, but interested to find the best practice tools to pick up, as its such a promising area for the future. I guess like a lot of Delphi programmers, if we are going to pick up web development (and seems to be the mainstream for the future) we are naturally biased towards something as powerful, great IDE and well designed language as we have been blessed with in Delphi. * Have heard comments in the past that the best state of the Art IDE is some of the Java ones (ie better than Visual Studio or Delphi) * Haven't seen anyone comment on Ruby yet * Web development is certainly an area where the open source and free tools are often equal to or ahead of the commercial tools * Open source tools starting with HTML editing like Kompozer are often well integrated with W3C standards (including validating HTML code). The W3C site is an excellent starting reference for good standards. * Waiting for comments from people like Gary B and others who have done very comprehensive PHP projects, for which there are very extensive frameworks out there. They seem to be able to turn out large systems with ease and speed of development comparable to Delphi, including excellent controls, Ajax, web commerce and ordering modules, and of course as good integration with Firebird as Delphi has. * I had the impression that the various extensions to Firefox (Firebug, Greasemonkey, Javascript viewers, error console etc) have generally been thought to be the best tools for web developers in browsers. Don't know much as don't personally use these much, but being involved on the Firefox development forum I know they are redoing these tools constantly - the View HTML Source etc are getting makeovers at the moment. Latest Firefox is a joy to use btw (V7.0a1 alpha nightly build - yes its 3 versions ahead). All the latest browsers (ie9, Firefox, Opera, Chrome) seem to be rewriting the state of the art constantly which is a great thing.

Re: [DUG] Delphi 2007 Vista
I have found a couple of minor oddities like this with one program starting another under Windows 7 – I also have a menu program that starts others, one of them an update program. This update program does run but does not show over other windows – mainly because I get a UAC prompt about allowing it, which I do, and then the program runs OK but the main form does not maximise always, but can see it on the task bar. Other things to check out are if the program stores data – eg in an ini file on the same path as the application.If this is under the “Program Files” folder you are very likely to get problems as this is a no-no place to write data and Windows will try to move such files elsewhere. Check the Activate or FormShow event of the program to see if it is writing any data just in case. Also my firewall (COMODO) has a habit of blocking a newly built program by saying its trying to install a global hook and asking me to OK that. This blocks showing of the main form too. After OKing it there is still a delay of several seconds until the form appears. Subsequent runs of the same exe are OK. Aside - UAC is quite smart – I have deduced that a UAC permission can inherit to a program started by the original process if it has been OK’d with a UAC prompt, because subsequent runs of the program started by another will not ask for UAC, as long as one of the previous programs that started it was granted that permission. Restarting the programs concerned brings another UAC prompt. (Lets not start a discussion here on the merits of UAC btw – although my opinion is anyone from the Unix/linux world is likely to approve of it).

[DUG] API to Windows explorer
I am writing a program to copy one or more folder trees to a USB drive (an extra backup regime for some Canterbury firms who were not able to get at servers or finding their offsite backups were also inaccessible). I have a nice component HAHFindFile to build the list of folders and files in a stringlist, and a routine using TFilestream to do the copy, but I was thinking its almost certainly going to be faster and more robust if there were an API to Windows Explorer to pass the source and destination folders to, and some parameters (eg copy only newer). I read technical articles from Mark Russinovitch about how Vista and Windows 7 optimise copying files over a network, varying the block sizes etc and using caching so I would expect an OS-level API to be much faster. Does anyone know if such an API exists, and are there options to eg copy only later files. I saw some hints in Google about a COM interface to Windows Explorer, but no details if it has options like I am interested in. Aside – I heard of one firm that had a server and a Wifi router on a UPS that had their network guy park outside with a wifi laptop and copy stuff from the server before the UPS died.

Re: [DUG] API to Windows explorer
Good grief lighten up! From what I heard - using a WiFi connection from the street was not a plan for disaster recovery, it was good kiwi improvisation. The point I was making was that in Christchurch in 2011, as happened in Greymouth around 1986 with floods, I dealt with firms where the office was destroyed, and the supposedly safe offsite backups also was unavailable. In Christchurch in an equally damaged and inaccessible network providers office, in Greymouth in a flooded bank vault. Extra redundant backup options are a great idea.

The statement form2.close is being executed but is not closing the form. What can stop a modal form being closed, or any ideas what I need to do to get it to close by itself when its finished? (The form is opened by form2.ShowModal and the code is in a procedure executed from the OnActivate event - the Show event also doesn’t work) John___ NZ Borland Developers Group - Delphi mailing list Post: delphi@delphi.org.nz Admin: http://delphi.org.nz/mailman/listinfo/delphi Unsubscribe: send an email to delphi-requ...@delphi.org.nz with Subject: unsubscribe
Re: [DUG] D2007 Upgrading Indy to V10.2.3
Yes that gave me the hint. The DCP files get placed in obscure places on XP and Windows 7 (and different on each) so in the end I did it the safe way and took the source folder to the second machine (the VM) and built all the BPL’s there in the target IDE. I guess that meant that it knew where the DCPs etc ended up. The other main trick is for each DPK that gets built to be careful to set the project options folders for the BPL and the DCU, as both sets are needed in the IDE. John Hi John, You may need the DCP files as well: IndyCore, IndyProtocols, IndySystem. Probably later versions than the '100' indicated in your error msg.

[DUG] D2007 Upgrading Indy to V10.2.3
I have been trying to upgrade D2007 to use Indy 10.2.3 rather than the default installed 10.1.5. It looks to be a minefield, as the web site instructions do not make it clear how to do D2007 in particular as it was a binary compatible clone of D2006. The Indy BPL files are all called Indy100.bpl etc rather than Indy110.bpl. Also it has Indy DCU files installed in various places. Does anyone have references or experience in upgrading Indy to share, as I have never upgraded a part of the IDE in place before and it is likely I am going to stuff it up. I kept folders of the old files it said to uninstall and delete, but I doubt I would ever get them back in the IDE correctly. If the IDE gets messed up: I presume I can copy the entire “Program Files\Codegear\RAD Studio\5.0” folder from external backup, – does this type of operation (uninstalling/ installing BPLs etc) make registry changes which also would have to be wound back? Or will I have to reinstall the entire IDE including hotfixes?

Re: [DUG] Mapped drives
When you map the drive tick the optiion to “Restore mapping on logon”. That way if a user loses the mapping you can just tell them to log out and logon again to fix it. As long as the network connection is there when the PC starts that normally works fine. If it doesn’t can be because a password is required to connect to the network drive and for some reason its not being remembered behind the scenes, or the network connection is not available at login.

Re: [DUG] Object was open
[DUG] Rhino MocksThis may not be the problem, but I have the impression its generally cleaner to make sure a dataset is closed before altering either the query or parameters or other linkages to data providers etc. You may wish to make sure there is an optional close action as in: if ClientDataSet1.active then ClientDataSet1.close; == maybe add this ADOQueryEdit.SQL.Text:=’x’; DataSetProvider1.Dataset:=ADOQueryEdit; ClientDataSet1.Providername:=DataSetProvider1; ClientDataSet1.FetchParams; ClientDataSet1.Open; (not all of those steps may be needed, but the Fetchparams is needed it the parameters in the SQL change as well). I am guessing the problem is the dataset is open when you try to alter the linkages such as trying to connect a different query.

Re: [DUG] Windows 7 Network Oddity
How do you expand the path to UNC? The reason I am surprised in a way that MS have done this is that using mapped drives added a layer of abstraction from the server – if a server had F: mapped to \\SERVER01\DATA then the server could be replaced, the mapping moved to \\SERVER02\DATA on the workstation in Windows Explorer, and the existing shortcuts and saved setups needed no change – in practice this is very convenient because it gave a very easy way to upgrade a server. Also the network upgraders only needed to know to edit the drive mappings in Explorer, now they might need to go into software packages and alter settings for each. I can cater for this in my settings, but it means that any time a server is replaced the settings will have to be edited, and the shortcuts will also will probably have to be edited, as usually the server name changes. I already have to cater for this for network printers, eg a printer might move from being called HPLaserjet and changed from being mapped to \\SERVER01\HPLASER changed to \\SERVER02\HPLASER so in a sense its just more of the same (printers never had a mapping anyway). John I havent noticed it as I have always expanded the path to unc and beyond so that no matter what form they give me for the path, it always evaluates to the same string. Another thing that may effect you is that on 64 bit server using TS - constant crashes are being attributed to this issue. And the workaround has been reported by other companies such as seagate - not to uses shared drives. The error given is C006.

Re: [DUG] Variabels stored
There is another way as well, you can declare simple global variables –
depending where you declare it determines it’s scope - how visible it it is.
In this example string2 can be seen by any unit that uses this one, just as
Form11 (the particular instance of TForm11, and is also a global variable) is
visible.
String3 can be seen by all procedures in this unit, but not by anywhere else.
If you have lots of simple variables to store and they don’t need to be
inherited etc this is the simplest way to do it.
You can take this further:
If I have lots of constants to declare, or variables to store I create a unit
which is code only (no classes) eg called storeunit and declare all the
constants and variables I want there, any form or unit that wants access to all
these variables just has to add storeunit to its uses clause. This
centralises all such declarations in one place away from a form and is very
tidy. I will often put simple global functions and procedures in here too, as
they also become globally available, eg various standard ways for formatting
dates and strings. Also this unit can be uses in different projects as well.
For this just go to File/New/Unit and the IDE gives you a new blank unit
already to add stuff to – a simpler unit with no form or class stuff.
Here string4 string5 integer1 integer2 integer3 can all be seen from anywhere
that uses Storeunit
It depends on whether you like using global variables or not. Also its a good
idea to use a clear naming convention for such variables.
There are other tricks you can do too - you can alter compiler settings to
allow assignable constants for a procedure, then any values assigned here will
be preserved between calls to the procedure. But that seems to be confusing
to me, as it really becomes a variable and not a constant. I saw that used in
and example where the program wanted a counter of the number of times the
procedure was called, and the counter constant in the procedure was assigned a
new value each time the procedure was called, its quite a tidy way to do that
sort of thing. In this case the scope (visibility) of the variable is totally
limited to the one procedure.
type
TForm11 = class(TForm)
Button1: TButton;
procedure Button1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
MyString : string;
end;
var
Form11: TForm11;
string2: string;
implementation
uses storeunit;
{$R *.dfm}
var
string3: string;
procedure TForm11.Button1Click(Sender: TObject);
begin
MyString := 'Hello, world!';
string2:=’Hello world2’;
string5:=’Hello world5’;
end;
unit Storeunit;
interface
var
string4:string;
string5:string;
integer1:integer;
integer2:integer;
integer3:integer;
implementation
end.

If you are going to declare a constant and then use a compiler switch to make it behave like a variable, then be honest and just use a variable!! Typed constants cannot even be used where “normal” constants can be: const ONE: Integer = 1; procedure Foo(aIndex: Integer = ONE); // ERROR: Constant expression expected or: case iValue of ONE: ; // ERROR: Constant expression expected end; Remove the type declaration from the ONE const, and both compile just fine (note that this is independent of the Assigned Typed Constants compiler setting). A typed constant is to all intents and purposes a variable, and might as well be declared as such (note that you can initialise a unit variable as part of it’s declaration): var ONE: Integer = 1; One final comment – Delphi really has no concept of a “global” variable. The highest visibility is “unit variable”. You still have to explicitly “use” a unit to bring it into scope, and if two units declare variables of the same name normal scoping rules apply but you can explicitly qualify a reference using the unit name if you need to override the default scope. Most of the time global/unit variable is close enough that the distinction doesn’t matter, but when it comes to dogma the old rules that “global variables are the spawn of Satan himself” needs to be tempered in Delphi with the fact that they are a bit better “behaved” than the sort of global variable that those ritualistic rules were originally devised for. However, it is still true that the occasions when a unit variable is called for are relatively few, but they should not be simply outlawed for being something they are not.

Re: [DUG] How to replace a file currently in use (Windows)
I do it slightly differently – I have a dedicated loader program which can update a number of files and programs in one go. It runs as the startup/splash screen for the main app menu. Updated programs are in an update folder, working programs are in a (local) folder It does: -Reads a list of files to check -copies any newer files from the update folder to the working folder -because it only copies newer files it is fast. -checks the dates and times of all files afterwards, and retries a second way if any discrepancies. Logs progress and errors. Warns if any not latest. -runs the main menu program and quits. -Main menu also periodically checks same list for pending updates and turns the “get updates” button bright yellow. -If “Get updates” clicked it runs the updater program and quits. Main smart is to check date and time file stamps are within 10 seconds to be the same. Different file systems have different time granularities (FAT32 I think is around 2 seconds and NTFS is milliseconds I think) so if you copy from one to another the dates and times will likely be slightly different if update and working folders are on different filesystems. (Also the updater program is the only one run from the updates folder – all others from working folder) This sort of scheme is used by Firefox too – it runs a program updater.exe and quits, updater.exe does the updates (usually a number of files are updated), and then runs firefox again. function xfFilesChanged(file1: string; file2: string): integer; //check 2 files modification date //returns 0=both files same, 1=file1 later, 2=file2 later //if within 10secs counted as same //note if one file does not exist, returns other as later var fileage1, fileage2: integer; dtdate1, dtdate2, dt10secs: TDateTime; begin result := 0; fileage1 := FileAge(file1); fileage2 := FileAge(file2); if (fileage1 0) and (fileage2 0) then begin result := 2; exit; end; if (fileage2 0) and (fileage1 0) then begin result := 1; exit; end; if (fileage1 0) or (fileage2 0) then exit; //maybe both don't exist dtdate1 := FileDatetoDateTime(fileage1); dtdate2 := FileDatetoDateTime(fileage2); if dtdate1 = dtdate2 then begin result := 0; exit; end; //now if not same, check if within 10 secs //in case of different filesystems dt10secs := encodetime(0, 0, 10, 0); if (dtdate2 (dtdate1 - dt10secs)) and (dtdate2 (dtdate1 + dt10secs)) then begin result := 0; exit; end; //still different if dtdate1 dtdate2 then result := 1 else result := 2; end; John ___ NZ Borland Developers Group - Delphi mailing list Post: delphi@delphi.org.nz Admin: http://delphi.org.nz/mailman/listinfo/delphi Unsubscribe: send an email to delphi-requ...@delphi.org.nz with Subject: unsubscribe
[DUG] Is this a hardware fault or IDE bug?
D2007 IDE – I have noticed a consistent problem – when the PC gets hot, the cursor will unexpectedly jump to wherever the mouse pointer/insert pointer is, and typing happens there. As you can imagine its a good way to wreck perfectly good code!. I am assuming its a fault in the hardware as it only seems to happen when it gets hot. But I have only seen it in D2007, not other software so I am wondering. So – has anyone else has ever noticed any such problem with D2007?

Re: [DUG] Problem redeeming Delphi XE BOGO free product
?Yes I find I have to run more than one browser to get every web site working. I take it to the extreme admittedly - I have Firefox V4 beta 8 pre-release (nightly build), Chrome, Chrome V10 beta (Canary build), Opera v10, IE9 beta. My internet banking was not working with Firefox V4 for a while - now is, Air New Zealand complains about any browser it doesn't recognise. MS small business server remote connection only works with IE (as it runs an ActiveX RDC). Some web sites redirect to the mobile version of a page for any browser they don't recognise (bad website design). In general though the beta builds are all very impressive, better, more reliable and faster than the standard releases. Favourites are Firefox V4 (wait until you see how fast it starts up - under 10 secs to page loaded - and the Panorama tab view). Chrome Canary build is refreshing too (its very yellow!). As far as pure speed goes, its a fight between Canary and Opera, but Firefox is very close behind. Firefox uses least memory because of not having a separate process for every tab - for instance it does handle 200+ tabs using same memory as most other browsers with 10-20 tabs.

Re: [DUG] Problem redeeming Delphi XE BOGO free product
?[Browsers contd] 10 seconds to page loaded is impressive when there are 269 tabs open in 20 groups, current group has 20+ tabs so all of those are pretty much loaded too - so yes that is fast. 1 or 2 tabs is a lot faster again. lots of tabs is useful if the browser handles it effortlessly, rather than bookmarking and closing them I just leave them open.Particularly useful for tabs I don't want to bookmark or keep long-term, and will only refer to for a day or so. Think of it as an alternative to bookmarks and opening bookmarks. Firefox Panorama allows one to organise open tabs into different groups, and drag and drop them from one group to another. The browser is pretty much only dealing with the one current group of tabs at once (others are a keystroke or two away). Its like the multiple desktops available in linux, or MacOS. This is Off-topic - but relevant to Delphi in that these are new paradigms about how to handle more objects than fit in a menu or dropdown list. The Vista/Windows 7 way is to make a terrific search box. The Delphi XE IDE (IDE insight) and Windows Live Mail filtering does the same idea. The MS Office way is to introduce the ribbon menus to find options more easily. In Delphi applications the most usual approach is to filter a large dataset in a grid. The Firefox Panorama is quite a new paradigm - organise groups visually on screen yourself by spatial placement - the user chooses the size and placement. Way more intuitive than folders. Its an outstanding design IMHO. There are some issues with it, (mainly speed but largely cured with hardware/graphics acceleration) but its as new an idea as the Ribbon in Office, or multi-touch. But worth checking out as such a design is likely to be used and copied in lots of other software in future. John Is 10 secs supposed to be impressive ? Chrome+ (note: NOT Google Chrome) 1.5.0 - start and load my iGoogle home page is 4 secs on my system (and that includes all widgets - TradeMe, Stuff, BBC F1 News, Stack Overflow, Delphi Feeds) having completed their initial update). handle 200+ tabs using same memory as most other browsers with 10-20 tabs. Whoop-de-doo... Show me a *USER* that can [productively] handle 10-20 tabs and I'd be surprised. :) 200+ tabs... useful for feature list bragging rights, but beyond that... ?

Re: [DUG] Problem redeeming Delphi XE BOGO free product
?Nope - I mean it organises your currently loaded tabs into different groups, and can show them in multiple ways including thumbnails. I do mean tabs into groups.

John From: Jolyon Smith Sent: Tuesday, December 14, 2010 4:59 PM To: 'NZ Borland Developers Group - Delphi List' Subject: Re: [DUG] Problem redeeming Delphi XE BOGO free product OK, looks like you (and perhaps FireFox) say tabs where I say thumb-nailed bookmark ;) A tab to me is a page actively loaded from a web site. Think of it as an alternative to bookmarks and opening bookmarks. From what I (briefly) have seen of Panorama, it's not a revolutionary new paradigm shift at all, it's just a better way to present and organise... bookmarks. 200+ bookmarks... yep, I can see organising those can be improved and useful. But that's not quite the same as 200+ actual web pages open in active browser tabs which is what I envisaged when you used the term tab in that context. And still, that being the case, opening 200+ thumbnails isn't the same as connecting to 200+ actual web sites. Panorama is just Chrome's Most visited page gallery taken to the next level. The MS Office way is to introduce the ribbon menus to find options more easily. ime the ribbons do the exact opposite!! They put options in obscure places AND disenfranchise the user - if you don't like where MS decide to put an option, tough - get used to it. ymmv :) In Delphi applications the most usual approach is to filter a large dataset in a grid. You are conflating a LOT of different and unrelated things here. Grouping and visualising bookmarked web sites is unlikely to have much in common with the need to filter data sets in an database application. The Firefox Panorama is quite a new paradigm - organise groups visually on screen yourself by spatial placement - the user chooses the size and placement. Actually, this is a very OLD idea. Windows 3.x Program Manager springs immediately to mind as representative of precisely the same new paradigm. Way more intuitive than folders. How so? Windows Explorer allows you to customise the size and placement of folders and even their appearance. Or put another way... Windows Explorer Desktop employs a familiar paradigm - organise groups visually on screen yourself by spatial placement - the user chooses the size and placement.

Re: [DUG] Web Sockets security hole
As I understand, a Web Socket connecting via a proxy can be fooled in the case of many proxies to connect to a different site altogether due to a weakness in the UPGRADE protocol which can be exploited by poisoning the DNS cache. The CONNECT protocol (not yet implemented) seems to be OK, and wss (Secure sockets may be ok). It looks like a hole in security for the way many or most proxies are implemented that affects Web Sockets going via them. I am still unsure how major this is and the implications, but as far as Opera and Firefox V4 are concerned they have turned off this protocol in HTML5 until it can be made secure. It looks like a relative of the DNS poisoning cache security hole that had major releases of patches by a wide range of suppliers done urgently about a year ago to fix a basic DNS flaw also involving poisoning the DNS cache to point browsers and HTTP traffic to the wrong IP address. My main questions were: is there much Delphi stuff out there using Web Sockets? and might this vulnerability with proxies something such people might need to take a look at (even if the proxy were not a Delphi product)?

Re: [DUG] Toolsets (was Re: Company closing)
I sort of disagree - A common VCL is the ideal solution. What makes Delphi a success on Windows is that it is Pascal and also close enough to the Windows controls that it produces what looks like native Windows applications, using the best of Windows XP/Vista/7 appearances. If they do a Mac version I reckon to be cool and admired has to be the same – it has to be close to the Cocoa interface and make native Mac applications. Each VCL control has to to give most or all of the latest mac control equivalents. That way there will be some differences – some properties of controls and events on Windows will not have an exact matching mac equivalentprobably the best is to just the property or event map to the matching equivalent on mac if its close, otherwise ignored. That way code can be moved back and forth, and some parts – eg some events will not work – so the programmers can attack them one at a time to insert the mac equivalent... cases like that you have almost no alternative but to have ifdef’d code, but hopefully manageably small cases. This is better than having a bland lowest common demominator VCL. There are some examples out there of cross platform applications and frameworks – these are quite a long way ahead of Delphi as far as cross platform, so unless Delphi can do it in a more elegant way than its been done already it may cater for Delphi apps but won’t pick up programmers from other languages. I think the main other successes out there are Webkit (whatever is used as core of Chrome and Safari) QT which I think is underneath Opera, XULRunner which is behind Firefox and Thunderbird. Apple have made cross platform versions of iTunes as well, and MS has mac versions of MSOffice – so these also must have some strategy for managing code across different OS’s. Java too – although in that case its mainly the JVM that is tailored to each OS? I would be most interested to hear more of how they all do it compared to what Delphi could do better. I am also involved in the Firefox community and one of the main debates there is how much the code and UI should be same across all and how much it should blend in with the OS themes and styling – the next version of Firefox (V4) for instance will get quite different appearances (more than now for instance) on XP, Windows 7, mac and linux to better fit in with each OS styling. John On 30 November 2010 09:56, Jolyon Smith jsm...@deltics.co.nz wrote: What we need is a Delphi for Cocoa. What we *don't* need is a Delphi (or a VCL) for a Lowest Common Denominator that fits Windows and Mac and Linux and phones and toasters and key-fobs. Totally agree with Jolyon. Initially, I was really looking forward to Delphi for Mac. But the more I think about it, solutions that are not based on the native GUI frameworks for each platform will most likely result in sub-par applications. If I want to design a cross-platform app for both Windows and Mac, then my design decision would be to refactor out all of the non-gui logic into their own units and then build separate user interfaces using the native UI components for each platform. As Jolyon stated, what makes sense/looks good in a Mac application does not necessarily make it appropriate for a Windows application and vice versa. If you want to do a proper job, you will most likely create seperate UI's for each platform. If that, being the case, it makes no sense to aim for that lowest common denominator because in the end you will please neither of your Windows or Mac users. I think Embarcadero's plan to use a common 'VCL will initially satisfy the uninitiated who wants to go cross-platform easily and quickly but will be annoying if you want to create apps that are designed specifically for the platform that they are to be hosted on. I see this as the same problem with the attempt to get existing Delphi applications Unicode-ready. The ideas was to make it easy for existing code to become Unicode but it made it confusing for new apps going forward. I think this will be the same for cross platform development for Delphi using this common VCL approach.

Re: [DUG] Upgrading to XE - Unicode strings questions
Iterating over a string is for the purpose of doing something with each
individual character..whether it is a ‘A’ or a 'A' with a ^ (caret) on
top of it. When I said the number of bytes in a character varies I was not
meaning the number of bytes in a Char - I was meaning the total number of
bytes in a one resulting character or letter might vary. For instance the
word fiancee (with an acute on the last e) has 7 characters, the last of
which might be 2 code units
When I iterate over a string I ideally want to get one character in the word
each time:
could I build a string like this?
setlength(String1,7);
string1[1] := 'f';
string1[2] := 'i';
string1[3] := 'a';
string1[4] := 'n';
string1[5] := 'c';
string1[6] := 'e';
string1[7] := 'e';//I would want the full e acute here
hence I want to be able to go
for i :=1 to length(string1) do
begin
thisChar:=string1[i];//get each character one at a time
listbox1.items.add('i=' + inttostr(i)+' character at position i
= ' +ThisChar;
end
I would be expecting to see 7 characters, 7 lines in the list box, and
length=7, with the last being e acute.
Now everything Jolyon are saying and Cary also implies that this is not
going to work. This looks to be a real nuisance!
Now I think the e acute could be one unicode character (as there is likely
to be a representation using one character, one code point and one code
unit) or as one character, two code units, 2*2 bytes - a surrogate pair -
where eg one supplies the e and one the acute. So it looks like what I see
might vary according to how the e acute is encoded in the string?
As I read further this gets murkier, as some of the things Cary Jensen says
are not the same as what you say even if you say it emphatically!
This is why I am thinking we have to understand clearly Unicode, and the
Windows implementation of it.and I don't really yet.
Here is what Cary Jensen says about a similar example with 7 characters, one
of which is a surrogate pair:
Although there are 7 characters in the printed string, the UnicodeString
contains 8 code
units, as returned by the Length function. Inspection of the 6th and 7th
elements of the
UnicodeString reveal the high and low surrogate values, each of which are
code units.
And, though the size of the UnicodeString is 16 bytes, ElementToCharLen
accurately
returns that there were a total of 7 code points in the string.
While these answers suffice for surrogate pairs, unfortunately, things are
not exactly the
same when it comes to composite characters. Specifically, when a
UnicodeString contains
at least one composite character, that composite character may occupy two or
more code
units, though only one actual character will appear in the displayed string.
Furthermore,
ElementToCharLen is designed specifically to handle surrogate pairs, and not
composite
characters.
Actually, composite characters introduce an issue of string normalization,
which is not
currently handled by Delphi's RTL (runtime library). When I asked Seppy
Bloom about this,
he replied that Microsoft has recently added normalization APIs (application
programming
interfaces) to some of the latest versions of Windows, ® including Windows®
Vista,
Windows® Server 2008, and Windows® 7.
Seppy was also kind enough to offer a code sample of how you might count the
number of
characters in a UnicodeString that includes at least one composite
character. I am
including this code here for your benefit, but I must offer these cautions.
First, this code
has not been thoroughly tested, and has not been certified. If you use it,
you do so at your
own risk. Second, be aware that this code will not work on pre-Windows XP
installations,
and will only work with Windows XP if you have installed the Microsoft
Internationalized
Domain Names (IDN) Mitigation APIs 1.1.
http://www.embarcadero.com/images/dm/technical-papers/delphi-unicode-migration.pdf
Elsewhere he implies that Delphi can handle normalised strings for
comparisons if one is careful, as in
var
s1, s2: String;
begin
ListBox1.Items.Clear;
s1 := 'Hell'#$006F + #$0308' W'#$006F + #$0308'rld';//make using
surrogate pairs
s2 := 'Hellö Wörld';
ListBox1.Items.Add(s1);
ListBox1.Items.Add(s2);
ListBox1.Items.Add(BoolToStr(s1 = s2, True));
ListBox1.Items.Add(BoolToStr(AnsiCompareStr(s1, s2) = 0, True));
The contents of ListBox1 are shown in the following figure.
Hellö Wörld
Hellö Wörld
False
True
Now I am not sure if the above example will show properly in email - because
email text is generally limited to the ASCII characters and lists like this
usually also restrict to text and not HTML emails. So as a related
exercise I am curious whether the above example prints OK on the
list..the words hello and world should have umlaut (..) over each o in
case it doesn't arrive like that on the list.

Re: [DUG] Upgrading to XE - Unicode strings questions
Thanks for the references, so I can answer most of the questions now. Here is what I understand so far, if anyone has anything to add this will be useful! Extra question: It looks like code like for i:=1 to length(string1) do begin DoSomethingWithOneChar(string1[i]); end; cannot be used reliably. The problems are that length(string1) looks like it cannot be safely used - as unicode characters may include 2 codepoints and length(string1) highlights that there is a difference between the number of unicode characters in a string and the number of codepoints. Still figuring out what is the best practice here, as I have quite a lot of string routines. Should be be OK as long as the unicode text actually is ASCII. Q2 – With XE do the .pas and .dfm files become unicode text and hence cannot be read by earlier Delphi, eg D2007 any more? Answer - Is a project option from what I have read?, yes not portable if unicode. Q3 – I do a lot of reading ascii data files, and writing back. Using mainly TFilestream and stringlists. Does this in general mean I will need to use file variables declared as Ansichar and AnsiString instead of Char and String? (I would prefer to use the standard VCL where possible) If I have variables as1:Ansistring; s2:string; Q4 – if I do s2:=as1 does this convert ansistrings to unicode? Answer - yes, there are performance issues to watch out for if conversion happens a lot. Q5 – if I do as1:=s2 does this convert a unicode string to ansistring? (otherwise how do I do this?) Answer - yes, there are performance issues to watch out for if conversion happens a lot. Q6 – I understand any code like char1:=string1[i]; if char1 in [‘a’..’z’] then begin message:=string[i]+’ - character is lowercase’; end will break, as ansi characters are ordinal (less than 256 or 512) and set comparisons ['a'..'z'] or ['a','b','c']can be used, this set code cannot be used for unicode characters. What is the replacement? Answer - There is CharInSet call and numerous extra housekeeping functions added in TCharacter. Q7 – do literals like #13#10 still mean carriage return and linefeed? #9 means tab? if I have code like (logline string1 string2 are string) logline:=FormatDateTime(‘dd-mmm- hh:nn:ss’,now) + string1 + #13#10+#9 + string2; ShowMessage(logline); Button1.hint:=logline; writeln(f,logline); these work D5-D2007 - ie a 2 line messagebox text, 2 line hint, and 2 lines written to a log file. is this still going to work? do carriage returns/tabs/other control characters have to be defined differently, eg as constants? Answer - not figured out yet - anyone else know? Q8 – stringlist1.loadfromfile(‘Test1.txt’); what happens if this file is ascii text being read into a stringlist which is unicode strings. Answer - Default is Ascii text for loadfromfile and savetofile, use overloaded routines for Unicode Q9 - stringlist1.savetofile(‘Test1.txt’) presumably this is no longer ascii text. How do I save and read a stringlist to/from a file if it is to be Ansi text? Q10 – If there are complexities in Q8 and Q9 is there a TAnsiStringlist type (for ansistrings) as well as a unicode TStringlist type? (I use stringlists a lot) Answer - unicodestring lists can save to ascii or unicode files, so TAnsiStringlist not needed. Q11 – do inifiles become unicode too? Answer - looks like no? Not clear? Anyone else know? Q12 – does Windows Notepad open unicode text files correctly? or can it only be used on Ansi text files? Anyone know this? Q13 - It looks like most programmers editors read and write ascii and unicode encoding.the one I use seems to distinguish between UTF-8 and unicode as well – what is the difference? Anyone know this?

Re: [DUG] Upgrading to XE - Unicode strings questions
My main remaining question is the best way to handle code that up to now looked like: for i:=1 to length(string1) do begin DoSomethingWithOneChar(string1[i]); end; If I got the gist correctly, string1[i] is one unicode character, but length(string1) is the number of codepoints in the string and not the number of characters. This is gonna be confusing! Other comments: Comment 1 - I saw quite a few commentators say that they in general approved of the way that the unicode had been implemented - everything that was ansi string before is now unicode consistently throughout the whole language and IDE, and in the main the only code that needs altering is where Delphi is communicating outside the standard language: ie -DLL calls -SavetoFile and LoadFromFile and other file access - even here smart defaults have been put in to retain expected behaviour. -Sending strings to COM/TCP etc you might need to convert to get the kind expected -Database fields - usually handled by making sure the right encoding is sent. Comment 2 - The worst inconveniences are for those who have already tried to do some unicode type processing using WideChar, and the functions that were used for these.Undoing these changes is usually the best way to cater for unicode.Also some of the routines introduced then have horribly confusing names, like AnsiPos which is for searching widechars and is still what should be used for searching.It seems to me that some identical routines should be introduced - eg called UnicodePos(.) just so that those who are new to Unicode can use at least a consistently named set of tools.I would probably make routines named like this which I use just to be clear. Comment 3 - I see a few people arguing that there should have been a compiler switch to allow compiling to ansistring or unicode string depending on the compiler switch, to ease converting people to D2009/XE. There are merits either way on this - in the long term if everyone is going to have to live in a unicode world then its probably better to bite the bullet and be made to convert code as eventually you cannot escape it. In such a case a simpler compiler and VCL is a big advantage. This is sort of related to being able to cross compile to 64 bit, iPhone, Android - whatever way makes it easy to have these forward looking options.The quite stark reality is that in 5 years it looks like much but not all commercial software will be running on Windows, its likely to be a mix of Web/iPhone/Android/GoogleOS/MacOS so the forwards portability of compiling Delphi for different environments is way more important than whether it should be able to do Strings as AnsiString. Comment 4 - Has anyone at Embarcadero considered 2 ways to make cross platform?option A is to go for a native compiler for different OS's - best if can be done. option B is the Java route - compile to intermediate code for a Delphi Virtual Machine which can run interpreted with a runtime on many OS's. Could be called the Delphi Virtual VCL Machine. The reason why this might be a good way to go is that Delphi was originally designed as a teaching language - ie formally very strongly typed and formally well structured language- it could be about the best candidate around for generalised compiling and a simple cross platform runtime. Also with Java now owned by Oracle there is questions over if it has such a bright future and there is room for another similar approach. DotNet is a similar idea too, but will only ever really be Windows. A Delphi Virtual Machine might not matter too much if its slower if its portable. [But I digress - The last point is way off topic for Unicode however] Comment and question 5 - What is the status of Free Pascal/Lazarus wrt to unicode?Does Delphi XE code port or not to Free Pascal?Its an issue to consider as well. ___ NZ Borland Developers Group - Delphi mailing list Post: delphi@delphi.org.nz Admin: http://delphi.org.nz/mailman/listinfo/delphi Unsubscribe: send an email to delphi-requ...@delphi.org.nz with Subject: unsubscribe
Re: [DUG] Upgrading to XE - Unicode strings questions
?As I understand it iterating over a string with Chars does get around the problem of surrogate pairs, as any character you are currently on might be either 1,2 or more bytes if it contains surrogate pairs, but just one unicode character. So if one is after iterating over the characters in the string your code should be perfect. My question is if you are not using for C in String1 do and want to use for i:=1 to length(string1) do what do you use instead of length to get the number of characters in the string in general? length is not the number of characters, its the umber of code-points (including surrogate pairs counted separately) if I understand correctly. Separate issue - I understand that if one wants to iterate over the bytes of a string then one uses byte rather than char, and then one does have to investigate each byte to see if it is part of a surrogate pair. There look to be routines for this – however I am guessing most won’t be needing to do this. Fortunately! Also – I think getting what we used to call the ASCII value of a character, or creating a character still works the same- in fact for english alphabet the codes are the same I understand? Can someone confirm. (ie the character might use 2 bytes if encoded as unicode string, but the value stored for ‘A’ is still 41 hex or 65 decimal. Which means I think that one can do code1,code2:integer; char1:ansichar; char2:char; char1:=’A’; char2:=’A’;//unicode char 2 bytes code1:=ord(char1); code2:=ord(char2); in this case I think code1=code2 ?? anyone confirm this. Of course once one goes away from English/latin 8859 characters this is no longer going to be true. John Doh! Thanks Jolyon for clearing that misunderstanding on my part. I was aware of the surrogate pair issue but I wrongly assumed that this might have been taken care by the iterator implementation. I guess not. Thanks again! Cheers, Colin On 23 November 2010 13:06, Jolyon Smith jsm...@deltics.co.nz wrote: Colin, the for C in loop and the for i := 1 to Length() loops are functionally identical! The only difference is that the “for in” version incurs the slight overhead of the enumerator framework invoked by the compiler and runtime magic to support that syntax. But in neither case will the loop itself help detect/respond to surrogate pairs (a single “WideChar” is potentially only ½ the data required to form a complete “character”). The only way to reduce an iterator over a string to a simple char-wise loop, whether explicit or using enumerators, is to first convert to UTF32, the facilities for which in the Delphi RTL are cough rudimentary, to put it politely. Non-existent may be nearer the mark. The precise mechanics of the loop construct used is not material to that problem. However, just as before Unicode when most people didn’t care and just wrote code that assumed ANSI==ASCII, these days people won’t care and will write code that assumes that Unicode==BMP (Basic Multilingual Plane), ignoring surrogate pairs just as they used to ignore extended ASCII and ANSI characters. And for most people, that will probably actually work.

[DUG] Upgrading to XE - Unicode strings questions
Planning upgrading from D2007 to XE, but want to read up on issues I will need to consider first to do with strings becoming Unicode by default. I recall the release of D2009 came with good white papers explaining ramifications, however I haven’t seen these as I haven’t upgraded. Asked for such also at the XE event but have not been sent anything yet. I have a lot of code which I want to plan to be able to recompile easily, and would like to plan this migration. I would prefer to put anything contentious or varying into a library unit, a ‘wrapper’ so that I don’t have to deal with these version differences in the main code... Anyone can answer any of these quick questions please post here or email me – thanks! Q1 - Anyone got some good references to read up on ansistring to unicode issues ? Comprehensive please! Q2 – With XE do the .pas and .dfm files become unicode text and hence cannot be read by earlier Delphi, eg D2007 any more? Q3 – I do a lot of reading ascii data files, and writing back. Using mainly TFilestream and stringlists. Does this in general mean I will need to use file variables declared as Ansichar and AnsiString instead of Char and String? (I would prefer to use the standard VCL where possible) If I have variables as1:Ansistring; s2:string; Q4 – if I do s2:=as1 does this convert ansistrings to unicode? Q5 – if I do as1:=s2 does this convert a unicode string to ansstring? (otherwise how do I do this?) Q6 – I understand any code like char1:=string1[i]; if char1 in [‘a’..’z’] then begin message:=string[i]+’ - character is lowercase’; end will break, as ansi characters are ordinal (less than 256 or 512) and set comparisons ['a'..'z'] or ['a','b','c']can be used, this set code cannot be used for unicode characters. What is the replacement? Q7 – do literals like #13#10 still mean carriage return and linefeed? #9 means tab? if I have code like (logline string1 string2 are string) logline:=FormatDateTime(‘dd-mmm- hh:nn:ss’,now) + string1 + #13#10+#9 + string2; ShowMessage(logline); Button1.hint:=logline; writeln(f,logline); these work D5-D2007 - ie a 2 line messagebox text, 2 line hint, and 2 lines written to a log file. is this still going to work? do carriage returns/tabs/other control characters have to be defined differently, eg as constants? Q8 – stringlist1.loadfromfile(‘Test1.txt’); what happens if this file is ascii text being read into a stringlist which is unicode strings. Q9 - stringlist1.savetofile(‘Test1.txt’) presumably this is no longer ascii text. How do I save and read a stringlist to/from a file if it is to be Ansi text? Q10 – If there are complexities in Q8 and Q9 is there a TAnsiStringlist type (for ansistrings) as well as a unicode TStringlist type? (I use stringlists a lot) Q11 – do inifiles become unicode too? Q12 – does Windows Notepad open unicode text files correctly? or can it only be used on Ansi text files? Q13 - It looks like most programmers editors read and write ascii and unicode encoding.the one I use seems to distinguish between UTF-8 and unicode as well – what is the difference?

Re: [DUG] D2010 and XE on the same machine
Is this IDEFixPack worth installing for D2007? This rings a bell – I might have tried this or something like it when D2007 first came out, and it made little difference. What really did make a huge difference was doubling my RAM. It was obviously having to swap different parts of the IDE into memory.

Re: [DUG] Solid State Drives
?Sort of similar config, except 32bit Windows 7 with 4GB Ram, and a VMware XP with D2007 and 1GB allocated. I find the performance of the VMWare virtual PC the worst aspect of it - the XP virtual machine is really prone to triggering intense disk writes - which looks like Windows XP starting swapping in the virtual PC, and resuming and suspending the virtual PC gives about 3 minutes of solid disk activity that kills the PC until finished. It almost looks like the virtual hard disk file is getting rewritten, and this triggers some kind of issue in the Windows 7 - the Windows 7 Resource Monitor shows the disk writes look to be to do with the VM hard disk file and the Windows 7 system volume information. Anyone have any tips how this can be tuned better? Most of the time its not Windows 7 running out of memory, as I keep an eye on this. Also have to say that both the VM and Windows 7 have D2007 installed and the performance of D2007 under Windows 7 native is much better - eg in the VM there is often a delay on hitting F9 before any compilation starts happening.

Re: [DUG] Delphi Specials
I agree, something with real limitations but real usefulness. A Turbo version would be great. Possible ideas would be 1 – Executables only run on the PC with the Turbo licence. otherwise full version but cheap 2 – Executables have a built in expiry date of 1 year from when compiled. otherwise full version but cheap 3 – Executables run only for 1 hour after started, or only 1 hour per day. otherwise full version but cheap 4 – Executables have a splash screen or title bar logo that cannot be removed saying “Turbo non commercial version” 5 – Will not compile units with more than 1000 lines of code or projects with more than 20 units. Should prevent any commercial projects 6 – Turbo version for students as E did – cannot install any components. otherwise full version but cheap7 7 – (My favourite). Full Delphi version, totally free, and you pay say $2 or $5/hr to use it, and you can’t get out of the charges – eg you have to buy credit like on a prepaid phone. 8 – They offer some combination of these schemes and you have some choice over which ones apply to you. And you cannot turn all of them off and get around the restrictions. I reckon any of these are not too hard to do, and people wanting a cheap version could do any hobby projects with them. If the restrictions are real and cannot be got around then make it a $40 version again for old times sake (Turbo Pascal type price) (except for option 7). How about these ideas Embarcadero? John Yeah. Both you and Wallace are talking about a non or semi commercial situation. I think for someone in business the pricing isn’t too bad but they don’t cover the non commercial market well at all. I don’t think they know how to provide a version that is useful enough for people to use it yet locked down enough that it doesn’t cannabilise their commercial sales. Their competitors that provide free versions either don’t need the full revenue stream (eg Microsoft) or aren’t commercial projects (eg Eclipse).

Re: [DUG] Delphi Specials
?Maybe a related topic - How to make it easy to upgrade. The main reasons I hear from others for not upgrading are (with my experience in brackets): 1 - locked into 3rd party components with no new versions or expensive new versions [I luckily have steered clear of addon components, except for a couple of simple ones with source that have no issues across versions. As a result typical time from install to adding components to compiling my real packages was last time 40 minutes. Cost was zero] 2 - Using printing (Quick reports etc) that has been replaced by Rave [I was well advised to upgrade before I coded any printing, as the earlier delphi versions of printing were crap, whereas Rave alone was worth the cost. Tend to agree - Rave reports have made printing easy.] 3 - Cost of upgrading [Workable. Bit the bullet and did it] 4 - Time to install a new and get used to a new IDE [40 minutes] I reckon for most people 1 2 and 4 are probably more important than 3. I reckon it might be worth while having a discussion about whether its better to avoid 3rd party components altogether and use just VCL to make it really easy to upgrade. I tend to get a lot out of standard VCL, particularly with stringgrids and DBGrids doing much of what the fancy commercial ones doing with some clever programming. And standard VCL with XP Manifest or Vista and Windows 7 Aero themes look really really nice. Eg the standard Datetime picker on Windows 7 is a stunner! Anyone seen it? it scrolls and zooms and slides really nicely. Free with Delphi (* note - Windows 7 required as separate purchase!) John Ian D I've watched the ongoing discussions re upgrading and costs .. I still use Delphi 5, and it supports the two products I have out there reasonably well. I say reasonably well, in that I'd love to move on to using SQL databases instead of Paradox, and to use the later features that improve my productivity in the conversion. To connect to remote databases means a significant cost, in not only upgrading, but also moving from professional to a more expensive product. I have owned D2007 now for some 2 years, and struggle with the investment of time, on my own, to convert the 3rd party tools and report writer, in that it won't be paid for directly, neither the time or the cost of the new product. So.

Re: [DUG] Delphi Specials
Well thats nuts. As a user of both Delphi 5 and D2007, you would have to be nuts to want to work in D5 if you spend any time programming. It works, and quite well, but D2007 and later are so much nicer, and faster to do stuff.If you value your time and are programming for anything returning money then its worth it. Pro upgrades are only around 600-700 at the moment anyway. pro includes pretty much all that was in Enterprise back in D5 days I actually reckon Embarcadero could well put a say a 10 year expiry on the IDE. Lots of commercial software is much more brutal than that – for instance Window 2000 XP (pre SP2) are now out of support, no security updates and as we well know it really cannot be trusted without them. Or some kind of Turbo version. Or a free trial. Or maybe Embarcadero could do a low use version – ie you pay $2 or $5 per hour that you use it. Otherwise a free download. Now there’s a good idea! Languages like Delphi are a sort of cooperative venture. Either you pay with your money for occasional and rare updates or it dies. Otherwise get a free IDE like Eclipse, but these are also cooperative enterprises - make sure you give a good amount of time in enhancing them and improving them, otherwise you are likewise riding off the work of lots of others. Like everything else, it comes down to the simple equation of what works best for the dollars – “bangs for the bucks”. I reckon the bang for the bucks with Delphi has always been pretty good, especially after you can keep using it for over 10 years. Over 10 years I estimate I have purchased probably 8 versions of Windows. And I only have 1 pc at once...

Re: [DUG] Delphi Specials
Aw nuts you are just being a stirrer. I actually use D5 and D2007 both a lot for work. So thats my experience – I greatly prefer D2007. For me a pro upgrade is $600-700 so thats also true. The point about Windows updates are: MS updates Windows still (mind you only XP SP3 onwards now) not because they want to or like to but because the security holes are so big they would look really really bad if they didn’t. What I am saying is do not punish Borland and Embarcadero for making a product that was reliable and well usable for 10+ years. Reward them by spending a small amount of money to keep them in business. And into the bargain enjoy a much better version of Delphi. Another reason for having the latest is to make use of the XP and Aero theme support. In my mind, with that you hardly need 3rd party components because the standard VCL looks so good. I am grumpy about buying 8 versions of Windows mainly because I couldn’t move the licences from PC to PC and until windows 7 the OS was pretty crap anyhow. I have however moved Delphi from PC to PC and been grateful to be able to. I still have my D5 installation, only once I upgraded I never opened it again to compile anything. Not once – the new version worked straight away and I just jumped into it.In my case I jumped from D5 to D2006 with not the slightest hassle. To answer the original question, without customers the eventual future is that it will rather than die it once E gets insufficient revenue from it they will hopefully open source it. Then good people like Jeremy N and others will spend time fixing the bugs for free, and people like you will still keep complaining about unfixed bugs. Hopefully by that stage you will start helping with the coding. I come back to my original point – either you spend some time helping to fix the bugs or you pay for versions where others have done it for you.

You are free to have that view for yourself, but if a version of software works well enough for someone, suggesting that they should pay a not insignificant amount of money and incur the productivity penalty of having to familiarise with a significantly different version of the product is presumptive at best and nonsense at worst. Ø Pro upgrades are only around 600-700 at the moment anyway Nope. The poster is deemed unclean and not worthy of upgrade pricing anymore. New user license required. I believe this is what Embarcadero are currently calling their “Bog Off” promotion – Oh no, wait, that’s “BOGOF - Buy One Get One Free”, not “you haven’t kept upgrading so you can BOG OFF and use Visual Studio instead for all we care”. pro includes pretty much all that was in Enterprise back in D5 days Well, you still can’t connect to remote servers using the proprietary DB API. Doesn’t stop you using ADO of course, which makes the restriction even more ridiculous imho. And let’s think about this for a minute... you are suggesting that a version of the software which contains a bunch of stuff that wasn’t considered necessary for a particular user back when they bought their licenses and suggesting that getting those undesired/unnecessary features is a good reason to pay through the nose to get current now? for instance Window 2000 XP (pre SP2) are now out of support EXCUSE ME? Every version of Delphi goes “out of support”, in those terms, as soon as the next version is released. Windows 2000/XP don’t stop working when their support period ends either, just like Delphi (assuming there is still someone servicing product activation requests, for the more recent versions), but you DO still keep getting updates and fixes for MS products, LONG after their replacement products have been introduced.

[DUG] Rave printing
?I have a generalised routine for printing forms using Rave reports D2007.
I struck an interesting problem printing contents of a DBGrid showing
columns from a MSSQL database - I think its because the fields are null or a
type (eg binary) that ClientDataSets cannot display. Printing that column
gives an access violation. I want to have it print nothing of course for a
column with invalid or null or blank data, haven't yet figured out how to
skip them.
Here is the essential code that prints the columns of the grid, (I have
already set tab positions scaled to widths of the columns).
- I think this particular column (column 4 in this case) has nulls.
[here lcds is a TClientDataSet, lDBGrid is a TDBGrid, ThisField is aTField]
for rowptr := 1 to comprowmax do
begin
lcds.RecNo:=rowptr; //have to move around dataset
for colptr := 0 to compcolmax do
begin
ltext:='';
//column may not have a field associated...
if lDBGrid.Columns[colptr].Fieldname '' then
begin
ThisField:=lDBGrid.Columns[colptr].Field;
if not ThisField.IsNull then
lText:=lDBGrid.Fields[colptr].asString;==access violation
end;
printtab(ltext);
end;
println('');
end;
Any ideas how to bullet proof this?

[DUG] integer or int64
Quite a few built in Delphi functions accept either integer or int64 as an argument, I checked into inttostr for instance, in that case its asm code. I have quite a few standard number processing routines, and up to now have done one version for integer, and another for int64. Is it feasible to have an argument/parameter to a function that can be either (like Delphi does)? is it possible to test whether such an argument is either integer or int64? Related - Does anyone know if an int128 is on the cards down the track? (I have some functions that use numbers nearly up to int64 limit - 17 of the 18 digits decimal length) John ___ NZ Borland Developers Group - Delphi mailing list Post: delphi@delphi.org.nz Admin: http://delphi.org.nz/mailman/listinfo/delphi Unsubscribe: send an email to delphi-requ...@delphi.org.nz with Subject: unsubscribe
Re: [DUG] integer or int64
I have a calculator program, beyond certain size numbers it resorts to real
numbers, when sometimes I want exact integers.
eg 17! (17Factorial) is the highest I can get exactly (17*16*15 etc.), 18!
turns to a real number and I don't know if I am losing digits.
Another example of large numbers is time converted to milliseconds:
Thisint64:=strtoint(formatDateTime('mmddhhnnsszzz',now));(I
don't do arithmetic on that but it is 17 digits)
My main guess about int128 is that if it were there it could give real
numbers to a higher number of precision digits (only 15-16 with current
real).
would be cool to store numbers like
pi=3.141592653589793238462643383279502884197169399375105820974944 if my
memory serves me correctly. Delphi cannot provide such accuracy.
Reason I asked is I heard that after Windows 7 one of the supposed versions
of Windows being considered was a 128 bit version. Also 64bit Delphi on the
horizon suggests that larger integers might be coming.

[DUG] Pasting components from code
I have a source generation program to speed creating of sets of labels and
edit boxes on a form - which gives output like examples below.
I paste the code that goes in the DFM onto the form, and it creates all the
components - a neat Delphi trick for those who might not know.
My problem is that the OnEnter and OnExit events seem to disappear from
these components and I have to add them back manually, even though the code
was already in the unit when the paste was done. My detective work so far
seems to show that it depends on where the forward (first) declaration of
the event code is placed whether it is recognised or not - seems it has to
be above the {private} and {public} sections for the form
What are the rules for where such event code has to be declared? - I am
vague on this. I have heard others use generated code too, I am wondering
if they have tips or pitfalls like this to avoid.
(Aside - Personally I favour source generation like this a lot. It is cool
to do, ends up as fast as hand written code, and most importantly saves time
and introduces standard code structure that is easy to understand.)
(Further aside - this is code generated by the program for a new part of
itself. Its cool when a program can write its own code).
example of output from the code generation
// Forward declaration
procedure edtSOURCEINPUTEnter(Sender: TObject);
procedure edtSOURCEINPUTExit(Sender: TObject);
//Implementation --- edit enter and exit events for editing this
record
procedure Tform1.edtSOURCEINPUTEnter(Sender: TObject);
begin
(some code here)
end;
procedure Tform1.edtSOURCEINPUTExit(Sender: TObject);
begin
(some code here)
end;
And:
//Paste onto form
object lblSrcInpPath: TLabel
Left = 300
Top = 51
Width = 142
Height = 13
Caption = 'Path'
Font.Charset = DEFAULT_CHARSET
Font.Color = clBlack
Font.Height = -11
Font.Name = 'MS Sans Serif'
Font.Style = []
ParentFont = False
end
object edtSrcInpPath: TEdit
Left = 420
Top = 48
Width = 121
Height = 21
Font.Charset = DEFAULT_CHARSET
Font.Color = clNavy
Font.Height = -11
Font.Name = 'Tahoma'
Font.Style = [fsBold]
ParentFont = False
TabOrder = 1
Text = ''
Enabled = True
OnEnter = edtSOURCEINPUTEnter
OnExit = edtSOURCEINPUTExit
end
object lblSrcInpFileIn: TLabel
Left = 300
Top = 75
Width = 142
Height = 13
Caption = 'Filename without path'
Font.Charset = DEFAULT_CHARSET
Font.Color = clBlack
Font.Height = -11
Font.Name = 'MS Sans Serif'
Font.Style = []
ParentFont = False
end
object edtSrcInpFileIn: TEdit
Left = 420
Top = 72
Width = 121
Height = 21
Font.Charset = DEFAULT_CHARSET
Font.Color = clNavy
Font.Height = -11
Font.Name = 'Tahoma'
Font.Style = [fsBold]
ParentFont = False
TabOrder = 2
Text = ''
Enabled = True
OnEnter = edtSOURCEINPUTEnter
OnExit = edtSOURCEINPUTExit
end
etc

Re: [DUG] Pasting components from code
The correct spot being? (that was my question! - there looks to be rules I did not know about. ) Form inheritance - not applicable so much in this case, as the set of labels and edit boxes vary totally from case to case. I just got tired of the repetitive task of creating large sets of these one by one and aligning them - this program also does alignment. Also I might want to drop this onto an existing form. Label font different from edit font - these are taken from a template, so that is one of the options - color and style also can differ. John Why not form inheritence? Are you declaring the events in the correct spot for the form? BTW, you really want your Label font to be different to the Edit font? ___ NZ Borland Developers Group - Delphi mailing list Post: delphi@delphi.org.nz Admin: http://delphi.org.nz/mailman/listinfo/delphi Unsubscribe: send an email to delphi-requ...@delphi.org.nz with Subject: unsubscribe

Re: [DUG] Sending notification between programs
The property FILE_NOTIFY_CHANGE_LAST_WRITE looks like a possibility, as if structured data has just been written to a file this event should be triggered. The only gotcha seems to be that the better the caching is the less likely the event will fire - according to the help. Tricky. John John, Hi. What you want to use is WinAPI: FindFirstChangeNotification, FindNextChangeNotification and FindCloseChangeNotification in program B. Essentially, A writes to a file, and renames it. This causes the handle returned by FindFirstChangeNotification to be signaled. You can test for this using a loop and WaitForSingleObject / WaitForMulitipleObjects. You can even specify a timeout in the WaitXXX calls so that B wakes periodically, even if there are nothing signaled. When the WaitXXX function returns, you can check for the existence of the file.

Re: [DUG] Sending notification between programs
I had thought of something just like this, having something in the data being what B looks for and acts on, otherwise sleeps. However this makes it disk based, and B has to poll. I was hoping something simple in memory could wake up B rather than referring to the filesystem. The main disadvantage of using one of the approaches mentioned is that there is two things that have to work right for the communication, two things could break. Slight aside: You know there is one really cunning way to get A to signal to B that I have used in the past that involves sending nothing at all: B in a timer monitors the foreground window title bar of A P:array[0..256] of Char; GetWindowText(GetForeGroundWindow,p,256); ATNowNewTitle := p; then searches for certain text in it, if its there its a signal to do something.This assumes A has focus which worked fine in my case.I used it to automatically suspend an automated time logging whenever the reporting program for said logging was in focus, as it was likely to be searching the same data file.It was spooky how well that worked! (Every time the report program lost focus or closed the time logging resumed.)

I work on systems where some idiot used a decimal(9,0) as a PK and mixed it

same otherwise you force the server to use hash joins (v slow) and secondly use
the smallest key you can (I'm currently using a bigint derived from the server
time) I really can see no reason for using anything larger than a bigint for a
surrogate, you can use a generator (like I do) or identity for a client
high/low, if you are going to cluster the pk you want it to be sequential
MSSql 2008 offers a 'sequential guid' but that is 16 bytes versus 8 for a bigint

Dealing with index/ID field that is set as binary - here is the solution that
worked in case any one else comes across same
Note for MSSQL using such a field in a JOIN SQL statement would be perfectly
fine as normal, as MSSQL has a native binary type. Delphi ADO however does
not, so this is the hoops I had to jump through when its two different datasets
and I needed to get the value in order to open the other with SQL or as a
parameter
example - using a Company_ID from Comp table to open Contacts that belong to
that Company...
Comments from friends who know MSSQL - their opinion is that an ID/index
field that is binary is unusual practice - restricts what kind to indexes can
be made for instance. Anyone here have opinion on this? have others come
across ID/Index that is Binary often?
Step 1:
ADOQueryComp.SQL.Text:='select *, Cast(Company_ID as VARCHAR(10)) as
ACompID, CAST(Company_ID as INT) as DCOMPID from Company '+
'where Company_Name like '+likestr;
Note - Casting binary to string/Varchar does not work, but to integer does.
Go figure!
Step 2:
iCompanyID:=cdsComp.FieldbyName('DCompID').asinteger;
ADOQueryContact.SQL.Text:='select * from Contact '+
'where Company_ID = CAST('+inttostr(iCompanyID)+' AS BINARY(8))';

[DUG] MSSQL ID field binary(8)
Dealing with a MSSQL database where the ID field is defined as Binary ( 8 ) and
using D2007 / ADO. I can open the table and read in data, but I cannot figure
out:
1 - how to get the ID value out of this field - when displayed a grid shows
this column as (BYTES), if I try to get the value as a variant then as a string
I get an empty string
TheCompanyID_I_Want:=TABLE1.FieldByName('COMPANY_ID').asXDataType;
ie what datatype XDataType do I need to use to get the value ??
The best light I could shed on it with Google was a hint that this type might
arrive as an array of Bytes - in which case how to process that?
2 - All I want to do with this value is to put in into a subsequent SQL
statement on another table to do a further select of all records with this
ID
qryTable2.SQL.Text := 'SELECT * FROM TABLE2 WHERE COMPANY_ID =
'+XDataTypeToString(TheCompanyID_I_Want);
Sorry for asking what is probably a dumb question, but its late at night and I
am stuck. And as Einstein said He who asks a question is a fool for a moment
- he who doesn't ask a question is a fool forever

Re: [DUG] faster TreeView
Any good reference tutorials on using this? I looked at it some years ago and was quite baffled where to start. Speaking as someone used to driving the drawcell events on standard stringgrids I would like to explore the stuff it can do. John Is that not also the one that Embarcadero use too in the Delphi IDe now?? I am sure I read/heard that. Jeremy On Sat, Jul 24, 2010 at 7:42 AM, Dennis Chuah dennis_cs_ch...@hotmail.com wrote: Hi.

Re: [DUG] 96DPI and 120DPI
Well as I understand using 120DPI is for the same reason - making app windows larger and easier to read on the screen - or at least the text larger. I have users with oldest to newest screens - from about 800x600 up to 1920x1024 so I have to do something like this for the form to be fairly consistent Mainly I want to figure out how to set my ScaleBy routine so its not thrown by 120DPI - how does it affect windows controls and their sizing - anyone there can shed clear light on this? Specifically are the screen.height screen.width figures still accurate, and does Screen.PixelsPerInch, and form1.pixelsPerInch return the correct values? Mainly I want to figure out there is a different relationship in grids between grid.width grid.defaultrowheight and grid.font.size - or maybe its as simple as doing the Form.ScaleBy before rather than after doing the grid adjustments... The main problem is I don't have a 120DPI screen to test on. If I am testing on a laptop is it feasible to set to 120DPI or will it mess up too much other general windows stuff? Also - does your stuff handle 144DPI? I saw references that that setting is also appearing - looks to be an option in Windows 7. John I've never used ScaleBy so cannot really help. I don't see that being useful in many cases. Operators often use large monitors with high resolutions so they can fit more app windows on the screen at the same time. Forcing the app to take up more space doesn't make sense to me.
