We brought TurboPowers Async Pro, oh, while before they open sourced, so we dont have any support now. But I wondered if anyone else on the list has seen or had this problem. We have an app. that captures data from a comport. It works fine etc., but sometimes we see a "Buffer is Empty" messagebox. The application is still logging in the background, but the message box is a pain. IT only happens every now and then tho. I dont know which buffer its saying is empty. I can only assume it might be the Transmit buffer. We dont transmit any data, so its kinda weired. I have never seen the error during development, as you never do :-) I DID notice that the RTS property is set to TRUE, and I think this should be FALSE as it does not need to know its RTS. Anyone know if its as simple as just this? or is the problem somewhere else? p.s. I have done a GREP search and found that "Buffer is Empty" is part of the Async Pro code BTW ;-) Cheers, Jeremy Coulter All email scanned with Nortons Antivirus 2003

As some of you may remember from late last week I put on a post about some issues that I thought were relasted to dodgy networking cable or a bit of dodgy hardware in out SQL server, and that progressed into Static arrays and all sorts. Ok, well, this has resolved some issues, BUT there is still a bit of dodgy hardware somewhere as sometime we will get lost connections still. SO, the user gets an error "Lost Conection" there something like that, and I have code that is MEANT to reconnect to the DB if it does diconnect, this is in an ADOConnection comp. but the code never seems to fire, and even if I try to trap the error using the ADOConnection comp, it still does not always trigger. BUT I should larify one thing. The forms are all static, and the error happens when the user tries to update or insert the data. The events are, press button, build SQL string, fire the queryits at this point that the user gets notified of the lost connection. I of course get panicy phone calls from users who dont want to loose their data etc. etc. etc. This sometimes only happens once a week, sometimes 2, depending on whats going on.

Re: [DUG]: SQL foolishness
Rohit
in the form without the loj, presumably you want
the result set to be rows from cln matched with
rows from the return of Get_Address where the
Ref_Numbers match.(right?)
So why isn't the query like this:
select count (cln.Ref_Number) from
Client_Main cln
, Get_Address ('PST','C',cln.Ref_Number) adr
where cln.Status = 'A'
and cln.Ref_Number = adr.Ref_Number
order by cln.First_Name
(i'm assuming Get_Address returns a row with a column
for Ref_Number)
I rarely use this method of combining rows (i use joins)
but when i do the where always links them in the same
way a join would.
does this make any sense?

I am really stuck here... PROBLEM The only solution I have is to use a calculated field at run-time. I cant define persistent fields as the query changes depending on user input. The list from the qry gets displayed and the user needs to deselect some rows. If I have a calculated field linked to a checkbox - then when he presses space or dbl- clicks on that column, I can fire a separate qry to record this in an exclusion table and because its a calculated field I can refresh the display to give him immediate feedback. if the exclusion table was joined to the query then I would have to refresh the query which can take several minutes I would not be able to provide immediate feedback. The only other soultion would have been multiple inserts from an sql statement - but that is not supported. Then I could have populated an inclusion table instead.

Re: [DUG]: OffTopic Batch file question
This being Friday, here's an answer to my own question ... if the exe being run by the .BAT file is a 16bit DOS exe then W95 will wait for it to finish before executing the next command in the .BAT file. if the exe being run is a 32 bit Win32 exe then w95 can (and does) start it and then continue executing the .BAT file (without waiting for the 32 bit exe to terminate) so ... if Steve's wait program is an old 16bit dosapp then this will in fact work as advertised. This also means that if you have some way to build your BAT steps as 16bit exe's (like an old Delphi 1 compiler) this problem would go away. (But why bother - you can just use the START command) Also ... Win95 did indeed support the START command (earlier i said i wasn't sure). You may want to test whether /w and /wait options are accepted by all the platforms you need to run this on - ISTR some difference (like /wait is required by some) but can't remember the details.(Suggest testing - help is notoriously wrong about this kind of thing).

Re: [DUG]: Windows quirks and inexperienced users
if i'm following this correctly, i think the problem is that the "fax sent... " dialog is modal - so it blocks allkeystroke/mouse input sent to the main window of the app. one way to get around this (if it's your app) is to make that dialog modeless - and then enforce the "modal" features that you want (for example not allowing the user to do anything else until they cancel the dialog). If the dialog is modeless - then taskbar clicks and attempts to click into the main application window will work as expected. -nshttp://www.roserox.co.th - Original Message - From: [EMAIL PROTECTED] To: Multiple recipients of list delphi Sent: Friday, March 28, 2003 09:32 Subject: [DUG]: Windows quirks and inexperienced users Hi all I have a mail merge app which has a button for sending off a letter as a fax to the client. It has a dialog which comes back at the end of the process, saying "Fax sent to fax queue". In some instances, inexperienced users (not familiar with Windows) have sidetracked off to e.g. read an email, and then clicked back on the task bar item for the letters program again. When they try to exit the program, and it doesn't respond, they use ctrl-alt-delete! But if they'd looked on the task bar, they would have found another entry, which was the "Fax sent to fax queue" dialog, still waiting for the "OK" to be clicked. How do I help them out? Is there a way to change the behaviour of Windows, so that when clicking on a parent form, if there is a child form / dialog still outstanding (not dealt with), then it re-focuses to this? I'm new to Windows programming, so this may be a silly or easy question. Also, is it easy to trap the ctrl-alt-delete event and give a controlled response to the users desire to kill my app? Any suggestions appreciated. TIA. Dave Jollie Tower NZ IT 09 368 4259

Re: [DUG]: sql help please
i was waiting a bit for a more sage response, but ... could someone help me with my query please? I have the following tables /* snip ... */ Some skills are required in more than one job. If this person has both those jobs and doesnt have that skill, then the query returns the skill for as many times as it is needed. What i really want, is for the skill itsself to be only returned once, with the earliest timeperiod. Is this possible in SQL or do i need to frig with code? (distinct isnt working with all my joins) i think the problem with the DISTINCT might not be "all the joins", but instead thatthat different time periodsmake rows with the same skill different so they both show up. in similar situations i've handled this in 2 different ways. 1) use GROUP BY on all the distinct columns with MIN() on the time period column. 2) write a SP (in IB or Oracle where SPs can return rowsets) or a Function (in MSSQL after 7.0) that does the select with ORDER BY on the time period , fetchs one (the first) row into the return arguments of the SP and then returns. neither very elegant i'm afraid, but maybe you will find it useful -nshttp://www.roserox.co.th

Re: [DUG]: To CASE or not?
if by filetype you mean a 3 byte extension (like .pas or .txt) and you can constrain the character set (say to case-indifferent alpha, digits and a few special characters like '$' and ' ' and '_') then you have about 40^3 (about 65k) possible file types. you could comfortably hold an array of 65k byte codes for include/exclude/whatever and map each 3byte filetype directly to an integer index into this array. BTW you can use a similar trick to quickly generate the index into the table from the 3 byte filetype: construct 3 tables of 256 integers (1 for each possible character in each of the 3 positions 1,2,3 of the filetype) - then sum those integers to create the index into the 65k array. if you have a lot of filetypes this will be faster than doing searching lookups into a table of 65000 codes. -ns http://www.roserox.co.th - Original Message - From: Alistair George [EMAIL PROTECTED] To: Multiple recipients of list delphi [EMAIL PROTECTED] Sent: Tuesday, October 15, 2002 07:02 Subject: [DUG]: To CASE or not?

i don't know much about Topspeed - but if they have anything like a trigger (and you can make a slight modification to the database) you could add an insert trigger to the interesting table and a small insertlog table (keyed on timestamp or something) - and then log interesting inserts to this insertlog your monitor process could read stuff out of this table FIFO and delete the entries after it does whatever you need to do to each record. doing it this way would guarantee you do things in the right order and also avoid needing to scan the whole monster table looking for changes or counting records. -ns http://www.roserox.co.th - Original Message - From: vss [EMAIL PROTECTED] To: Multiple recipients of list delphi [EMAIL PROTECTED] Sent: Friday, October 11, 2002 05:11 Subject: [DUG]: Whats going to be best thing to do?

What we are trying ot do is when some data goes into a specific table, it has to get that record, and do something with it. Whats going to be the best way to do this do you think? My thoughts have been:- (1). do a record count and when the count is diff. go and get the new record.BUT what if 3 entries have been added...how do you know 3 have been added? what about, you go to get the last record, but another 2 have been added since you did the r/countdont think this is an option (2). SOMEHOW monitor the table so that as stuff is added do something. (3). Get the people who wrote the app. to make a mod that writes the data to an identical table (structurally) and then r/count this. if its 0 then it loop the records. #3 seems to me the best...just costly. The other problem IS, that we are trying to makeit as quick as poss. as the data is being posted onto a webpage, and at the moment usething the method we are using not, its about 1-2 mins before the new appears.

This is what you want. The following is some asp script to show all the
server/browser variables. The item you need is HTTP_USER_AGENT
And you will get something back like this -
Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; T312461)
Which tells you I am running MS Internet explorer 5.5.

Re: [DUG]: Column Names
Title: Message Neven (not Nevan :) ) I still see it as a design limitation of TDataSet (or more precisely TField) since FieldNamedoesn't I don't think this has anything to do with TDataset The issue is what the result set column names are when columns in two joined tables have the same name. For example the following query in Interbase: select p.pat_id,a.pat_id from patient p join patient_alias a on (p.pat_id = a.pat_id) results in 2 columns "PAT_ID" and "PAT_ID1" There's no ambiguity here, but if you want more mnemonic names for the result columns you need to alias them in your select The "name" of the "field" (column) comes from the underlying DBMS not from TDataSet (I think this was Kyley's original point) Maybe I am missing YOUR original point g -nshttp://www.roserox.co.th a/ include a Table Qualifier or b/ defer to Origin for Uniqueness (my prefered solution) in fact the whole naming of TField betrays its origin as SQL Tables do not have fields Neven (not Nevan) - Original Message - From: Kyley Harris To: Multiple recipients of list delphi Sent: Wednesday, October 02, 2002 9:23 AM Subject: RE: [DUG]: Column Names Nevan, I wasn't implying that your SQL wasn't normal or correct.

Re: [DUG]: There's probably a simple explanation, but ...
What I do is keep all modules under sub-folders in a folder called v1_0 then when I generate v1_1 I copy whole folder and rename it - but project config still sets open files to old folder. Is there a better way to do this? i think a better way is to keep all modules under subfolders in a folder called (say) v_next and then when you release a version copy the whole folder to a new folder v1_1 (or whatever the version number is). This way the project and desktops alwaya refer to files in the v_next folders. You can also set the access to all the files in the copied folders to readonly so that if you open them (to compare old with new or whatever) you don't get your hands crossed and start modifying the wrong copy. -ns http://www.roserox.co.th --- New Zealand Delphi Users group - Delphi List - [EMAIL PROTECTED] Website: http://www.delphi.org.nz To UnSub, send email to: [EMAIL PROTECTED] with body of unsubscribe delphi Web Archive at: http://www.mail-archive.com/delphi%40delphi.org.nz/

I've noticed that there are two versions (overloaded) in sysUtils:

representation. }
function IntToStr(Value: Integer): string; overload;
function IntToStr(Value: Int64): string; overload;

Am I missing something here?, they seem to be identical.

Re: [DUG]: LockWindowUpdate
i've tried using LockWindowUpdate in situations where i had a few mutually dependent windows and was getting race-condition repainting when something changed in one of them. What i thought should work was LockWindowUpdate( True ); // make whatever change // let all the cascading side-effect events fire LockWindowUpdate( False); // force a refresh But (as you described) LockWindowUpdate has these wierd global effects on all the desktop windows not just yours. In my case it made the whole screen momentarily flash - really annoying. In both cases i've tried this i've ultimately fixed the problem some other way - like using control flags in Paint functions to suspend redrawing while things are unstable.

Re: [DUG]: Palladium - a concern for developers?
Take the current registration process as an example. My prediction is that once enough firms have registered for the next 2 years, Microsoft will indeed come out with a new office version that will read older versions but not write to that format. This means that if you stuck with an older version of say, Word, then you will be unable to read all those word documents that people keep sending you and wanting you to read. This makes it a requirement to upgrade at any cost. Especially if Microsoft makes it slightly annoying to load and read older versions even if they do have the latest, as it will cause peer pressure for smaller players to pay whatever is required to upgrade - and I suspect at that stage it will require a full purchase. I am no defender of microsoft. but how is this any different than a company that starts making audio CD players that don't play vinyl LP discs? Or a company that stops making VCR players and replaces them with DVD players?. Are you under peer pressure to replace your old VCR so you can look at the latest DVDs? Would you expect companies to manufacture DVD players that continue to play VCR tapes forever? As I say - i hate to get into the MS corner on this, but MS has a pretty good record of actually going the extra mile to keep things compatible 2 or 3 versions back (16 bit code for example, MS Office formats) and usually gives plenty of warning about deprecated features, and clear (well sort of clear) directions for developers. I agree some cautious attention is warranted - but really palladium is just an extension of the idea of signed applettes and downloaded executable code. The important thing is that they give transparent control the the system administrator and not bury it in some obscure rat's nest of registry keys so the whole system locks up if something goes wrong. fwiw -ns http://www.roserox.co.th --- New Zealand Delphi Users group - Delphi List - [EMAIL PROTECTED] Website: http://www.delphi.org.nz To UnSub, send email to: [EMAIL PROTECTED] with body of unsubscribe delphi Web Archive at: http://www.mail-archive.com/delphi%40delphi.org.nz/
Re: [DUG]: Palladium - a concern for developers?
But the point I was trying to make is that everytime you change your deisgn or release a new version of your electronic device you have to re-apply for the ISO standard and pay fees again to get the certification. ah - yes i see your point - fees. Yes this is just like that. Every time you change something you have to reapply (and pay). and yes that is a killer for us small developers. I wonder what this means for custom software? If we develop an application for a single customer and they want to run it on a palladium secure box do we have to recertify every time we fix a bug? (Sounds like a good argument for breaking things into servlettes). Can the components be certified separately? (Time for me to RTFM on this i see). this is where the level of control the sysadmin will have really matters.

Re: [DUG]: Graphic in QR
Some things I would try (with only dim hope of success)
1. Setting the report units (i forget what this property is called)
to pixels. I think by default it's mm or twips and this can
result in some rounding anomalies.
2. with autosize false and stretch false try setting the dimensions
slightly larger than the known size (in both dimensions).
There are/were some known problems in QR with big bitmaps
but it doesn't sound like your logo is pushing that envelope.
Does reducing the size (e.g.. by reducing the colour density)
affect the problem?

Hi from a graphics novice
I have a company logo in a BMP file.
When I print this out from Corel PhotoPaint, straight with no
scaling or anything, it prints crisply with a size of about 30mm x
30mm.
I then drop a TQRImage onto a QuickReport band and do
LogoImage.Picture.Bitmap.LoadFromFile('Logo.bmp');
with Autosize set to true
and Stretch set to True
It tries to print it at about 120 x 120 mm
If I then set Autosize to False and set the LogoImage height and
width to 30mm It prints fuzzy - not half as clear as the same file
printed from PhotoPaint.
Does anyone have any experience that will help me with this?
I have tried saving the image in GIF format, with the same results.
TIA

Re: [DUG]: UNC Path Names
Sorry Paul I don't know the answer, but assume that you will probably have to iterate through the drives and look for a match for matching UNC name. right. you use WNetOpenEnum to set up an enum of RESOURCETYPE_DISK resources. then call WNetEnumResource to get them. You get back a NETRESOURCE structure for each resource. NETRESOURCE has the localname and remotename so you can search through these pairs to find one matching your UNC path. Note that it's possible to have more than one drive mapped to the same UNC path so this mapping isn't well defined (the drive letter mapped to \\mybox\myshare needn't be unique. BTW the inverse mapping is much more straightforward - just use WNetGetConnection. WNetGetConnection maps local names (i.e. mapped drive letters) to the UNC name of their corresponding network share. This is unique (the UNC name associated with a mapped drive letter is well defined) so somewhat less trouble. -ns http://www.roserox.co.th The ExtractFileDrive is meant to extract the drive letter from a file name eg.

Re: [DUG]: TNMSMTP
Oh and one more thing ... As a further test of whether this problem is something in the SMTP component or something in the OS settings can you please try a finger or ping command at the NT command line of the failing Win2000 environment?

Re: [DUG]: Event Log interaction with Delphi
The problem I have is then getting the event log to pickup the correct
message form the application. What I have tried is to create a StringTable
in a resource file like below, but currently I have had no success and are
still getting the default message.
STRINGTABLE
{
71006, My custom event message here
}
If anyone can shed some light on how to do this it would be greatly
appreciated
I've never done this in a Delphi App - but have using VC++ and that project
does it (I hope you are sitting down) like this:
as part of the application build, BEFORE the link or compile, it runs
a utility called MC.EXE
MC takes a text .MC file with messages (separated by blank lines) formatted
like this:
MessageID=
SymbolicName=MC_REBOOTSENTRYSTARTED
Language=English
Reboot sentry thread started
.
and produces as output 3 files:
(1) a C++ header file with defines like this:
//
// MessageId: MC_REBOOTSENTRYSTARTED
//
// MessageText:
//
// Reboot sentry thread started
//
#define MC_REBOOTSENTRYSTARTED 0x1009L
(2) a binary .bin file (call it MSG1.bin).
the program includes the .h file so it can reference the
#defined message identifiers in calls to the EventLog API.
(3) and a .rc file to include with the application resource
script .rc file for the app with lines like these:
LANGUAGE 0x9,0x1
1 11 MSG1.bin
When the application .rc script is compiled, it will use
the .bin file to create a type 11 binary resource which
is what the NT message system expects to find when formatting
messages.
It is one of Microsofts more spectacular examples of making
something that could be so simple absurdly complex.
The one problem that i don't see a way around is what you use
to compile the .mc file to create that binary resource.The
MC utility I'm using is part of the Win32 SDK - maybe you can
download it from the MS website - not sure.
BTW - one word of caution - debugging this stuff is a pain
because of DLL caching.
hope this is useful

I then have used a useful little application called Resource Hacker, and can confirm that the message table is now within the application. Unfortunately the application is still not logging correctly. On further examination with Resource Hacker on other applications that use the application log (Norton Antivirus and ASP.DLL) I noticed that the messages that I create come in as I specify them (i.e. specify 106 in the MC file, and it ends up as 106 in the application). All other applications seem to have unusual numbers in the application itself eg. 106, Test Message (%1!s!). (taken from my App) 1090453506, \n%1 1090453507, \n%1 (taken from the Norton Antivirus application.) (Norton AV responds to EventID's such as 7,14..etc which are no where to be seen in their message file) What I am wondering is if there is some constant that I need to add to my EventID's or anything else.

Re: [DUG]: Array of labels in QR
function GetMyLabel(Index:Integer): TQRLabel;
property MyLabels[Index: Integer]: TQRLabel read GetMyLabel;
default;
These two under Public Declarations?
i'd make GetMyLabel Protected or Private and property Mylabels Public.
Probably it doesn't much matter because you're not going
to access the property from outside the form anyway.
function GetMyLabel(Index:Integer):TQRLabel;
begin
// in production probably should do some error checking ...
return FindComponent(format('mylabel_%d',[Index]);
end;
This under Implementation
correct
Should it be result := [...]
oops - yes it should. (i've been writing C++ - i knew something
would creep in).
Should it be [...] MyLabels.FindComponent ...etc?
no.FindComponent searches the component list by name.
So you want to call the FindComponent method of the owner of your
QRLabels. This is the TForm.
I get error Undeclared identifier - MyLabels
If I leave MyLabels out I get error Undeclared identifier -
FindComponent.
I can see how FindComponent would work - I'm just tripped up on the
declaration details, I think.
see above.
I regret winging this - it's too confusing.Here is a revised
version of the functions (that DO compile and even work) which
should be a lot clearer.
Also, I've posted the full .pas and .dfm files here
http://roserox.co.th/dugnz/unit2.pas
http://roserox.co.th/dugnz/unit2.dfm
function TForm2.GetMyLabel(Index: Integer): TQRLabel;
var ret:TQRLabel;
begin
// in production probably should do some error checking ...
result:= FindComponent(format('qrlabel_%d',[Index])) as TQRLabel;
end;
procedure TForm2.Button1Click(Sender: TObject);
var i:integer;
begin
for i:=1 to 2 do mylabels[i].caption:='foo';
end;
The QReport in this demo program has two labels on it - QRLabel_1
and QR_Label_2

Re: [DUG]: Array of labels in QR
I don't see a way to get the Report to recognize
array elements in the report design.
But if your purpose is to be able to manipulate groups
of labels using an index you can use the following
shameless hack.
Adopt some naming scheme to identify the indexed labels
- say for example that the _n suffix will denote the
labels[n].
So now - at design time you put labels on your report
with names like mylabel_0 mylabel_1 etc
Then create a readonly property to the form that hosts
the report
function GetMyLabel(Index:Integer): TQRLabel;
property MyLabels[Index: Integer]: TQRLabel read GetMyLabel; default;
function GetMyLabel(Index:Integer):TQRLabel;
begin
// in production probably should do some error checking ...
return FindComponent(format('mylabel_%d',[Index]);
end;
Now you can do stuff like
for i:=0 until 9 do mylabels[i].caption:='foo';
i'm making this up as i write this so caveat emptor - it
may not even compile, and i certainly haven't tested it.

Re: [DUG]: Failure of OverNight routine
Mark I just wrote a trivial D5 app that has a form and writes 5000 lines to a memo control and then closes the main form (terminating). Not sure if this is a good simulation of what your app does - but if i start this and then lock my workstation - this app continues to run (writing to the display even though i can't see it) and then exits.It doesn't hang until i unlock or anything like that. So - if locking does impede apps that want to interact with the display it seems it impedes their STARTING some way, but doesn't stop them from executing. I don't have norton schedule (unless maybe its in the NAV somewhere) so i can't try that test. -ns - Original Message - From: Mark Howard [EMAIL PROTECTED] To: Multiple recipients of list delphi [EMAIL PROTECTED] Sent: Friday, September 21, 2001 9:36 AM Subject: Re: [DUG]: Failure of OverNight routine Further to this (below) - I get the same problem if (rather than Locking the computer) I just log out. Mark Don't think I have any tool that I could use to run a SQL script from a command line (D5 Pro). I can duplicate the problem on my own system. Put the executable in Norton Scheduler and wait for the designated time - it runs perfectly. Do the same but Lock the computer (the screen is blank apart from an Unlock dialog box). When the designated time arrives the screen does a blip the disk does a blip and nothing. When you Unlock the computer the utility completes the run. It appears to continue from a point at the start of accessing the database, but it's hard to say because the only code before that is writing a couple of lines to the Memo - which would happen pretty quick anyway. I find it hard to believe that Locking the computer would prevent an app getting access to the database (locking appears to be a prevention of access through standard input/output). I could believe that the app is stalling because it cannot display stuff on the (locked) screen. Unless I get any posts saying that this should not be a problem, I'll start rewriting it as a console app. Any comments?

Re: [DUG]: Help with Logic flows

Re: [DUG]: Foreign Language conversion.
A reasonable place to start is the Microsoft MSDN website. You can search it from here http://search.microsoft.com/us/dev/default.asp This kind of translation is known as localization (usually with a 'z') and searching MSDN on this keyword will get you a lot of material. If you are translating a program that has menus and messages (and control captions etc etc) in resources your task is much simplified. But often you will find programs that were not written with localization in mind will have text embedded in the sourcecode and this can be a big problem for you. Sometimes (often) it is worth some careful thought and perhaps some re-writing to add multiple language support into the application in a systematic way. Something else you need to be aware of is that if your target language uses 16-bit wide characters (Chinese does) you need to look carefully at the mechanisms in the program for handling message strings and buffering them because probably they are set up for 8-bit characters. Also - you usually need to worry about more than just translating menus and messages.You may need to be able to accept input in your local language. This means reading wide strings from text controls and saving them into databases.You have to be careful about buffer sizes, string library calls, sorting, comparing and stuff like that because all of these operations will need to be aware they are operating on wide strings. We've run into some of these problems (because we're in Thailand) but Thai script doesn't require wide charactersets so we haven't had to worry about most of the unicode issues. There is a company http://www.lingscape.com/ that makes some Delphi tools for multi language applications that you may want to investigate.I have never used their product - and my impression is that it is a more a tool for developing multi-language applications (rather than converting them). I hope this is enough to get you started.

Re: [DUG]: objectpal/D(anything) conversion
Bevan Thanks for the feedback In my experience it is often better (if not necessary) to rewrite rather than trying to run some sort of conversion. There are too many non-standard or ugly things in Paradox that can be handled much nicer in Delphi/BCB. I had pretty much come to this grim conclusion but wanted to be sure I wasn't missing some clever way out. I'm currently going through this exact same problem with a rather large and cumbersome Paradox project, which started off in version 4 for DOS! It has since progressed through almost every version to Paradox8 (by Corel), which I really despise now. So we've bitten the bullet and are currently converting to BCB and improving dramatically in the process. Hmmm really.I'd be interested in hearing more about this effort if it wouldn't be a lot of trouble. Why BCB instead of Delphi?Especially now that Kylix has arrived - or are you mostly C++ programmers? -ns --- New Zealand Delphi Users group - Delphi List - [EMAIL PROTECTED] Website: http://www.delphi.org.nz To UnSub, send email to: [EMAIL PROTECTED] with body of unsubscribe delphi Web Archive at: http://www.mail-archive.com/delphi%40delphi.org.nz/

Re: [DUG]: DB Grids
1: Can we disable entry in two out of every three rows? we had a situation where a grid displayed prices for products - but sometimes the price could be edited and sometimes not depending on some complicated (irrelevant) tests. You can do this if you monitor movement within the grid. The DataChange event will notify you when the focus shifts to a new row.Your handler can fiddle with the readonly property for each column to set these the way you want them for the current row. 2: Less importantly can we change the colour of the two detail rows? DBGrid.DrawDataCell will let you draw the cells yourself - you can do whatever you want. In the app i mentioned above we used different font colours. [the app i'm referring to has been through several versions of Delphi - so it may be that there are more modern ways to do this.
