Re: [DUG] FW: Web development
We have moved some of our stuff to Java, and are quite happy so far. In terms of rapid development (in the Java world), there are things like Spring Roo and Seam Forge, the latter being the newest and least documented... I have had a little look, but nothing serious so can't really comment that much (other than, it looks good, but then so do so many things until you did a bit deeper). In terms of wanting to stay away from HTML, CSS, etc, then there is Vaadin or even GWT (both Java related... we are playing with Vaadin at the moment). The thing with Java is there are so many frameworks and so many options it is easy to go around in circles trying to pick (what you think is) the best one. What we have used in a real project is JSF using Facelets and a little bit of Seam... there is a learning curve, but it is not too bad (we have not delved into Java EE, just using Tomcat). The Java IDE's are also really great, we have settled on Eclipse, but you will find passionate battles about that, as well as for the frameworks. Anyway, just thought I would through that in from left field... Happy hunting. Regards Colin On 3/06/2011, at 11:49 PM, Stefan Mueller wrote: I guess Jolon is still using MSIE, right? .. The developer tools that are built into Google Chrome browser for example are quite good for debugging HTML/CSS(and even JavaScript). Just right click on the elements whose markup you want to see and say inspect and it will show you all the code and css applied to the element with a nice little editor that allows you to play with and modify each property on the fly. Also, developer tools such as MS Visual Studio (I am doing mostly ASP.NET MVC stuff lately) aren't too bad either with features such as autocomplete/autolookups/warnings for non-closed html-tags and invalid markup/attributes, etc that makes writing valid HTML/CSS pretty easy. As for other opinions on this whole website development talk: I definitely would stay away from writing websites in Delphi. It might be ok to use if all you need is a small quick and dirty inhouse webapp or prototype .. but what you gain in familiarity by using Delphi is quickly offset by disadvantages. PHP/.NET/RoR have huge communities of developers - if you have a problem or need some example code/library then just google for it and you will most likely find something - whereas for Delphi it's mostly up to you to figure it out and then there is the thing about maintenance if you leave the company, will they still be able to find a Delphi developer to maintain and lock after the website?). I think it's better to go with more popular web development languages. Personally I am really happy developing with the ASP.NET MVC framework. Never really liked traditional ASP.NET WebForms (viewstate is just such a bloat and if you try to AJAX'ify the website things can quickly become very complicated and badly performing) - The new ASP.NET MVC on the other hand is absolutly fantastic in this regard and a joy to work with - the seperation of Data/GUI/Logic (MVC development pattern) is much better and more modular then the intermingled mess ASP.NET WebForms was. I also heard a lot of good about Ruby on Rails. As far as development goes it sounds easy and fast - but seems to have a bit of scaling problems (if your projects require that, most don't). PHP is probably the most popular web-language, but never really got to like it. I don't like weakly typed script languages that just break during execution ... I like my code to be compiled and raise errors during compilation time if I made some mistake - makes developing/changing existing code/database tables so much easier and less error prone if you have everything strong typed. ASP.NET also has a couple of goodies that I probably would miss a lot in PHP - like, automatic XSS injection prevention, URL-Rewriting, Localisation, Authorization (user login, roles, etc), HttpModules that allow you to plug directly into the web execution pipeline of the IIS webserver, etc. ... I think the ASP.NET framework makes writing secure and high performing websites a lot easier then PHP does.

Re: [DUG] Toolsets (was Re: Company closing)
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 Yes and No, Some people don't like it, some love it, I don't mind it... and that is java SWT based apps... Eclipse itself being a prime example. SWT uses native controls on each supported platform, and (I believe) truly fit well into/with the OS and seem to perform pretty well too. On a day to day basis I use a Mac, use a bit of Ubuntu, and use Delphi in a Windows virtual machine... Eclipse, and a small number of SWT applications I have built, fit pretty well into the native OS... the last little app we wrote sat alongside a Delphi app doing a very similar thing, and the user had no idea one was Delphi and one was SWT/java. In saying that, I don't think there is SWT on phones, toasters and key-fobs (well, actually I think there was a Windows mobile port... not sure how that went). Had a play with Android a while ago since I have an Android phone, not to mention the plugins for eclipse makes it a relatively easy way to develop, and it was not that hard (though I have forgotten it all now :-)) Like others have mentioned, learning the language was easy, learning the frameworks is more time consuming... SWT, Android, and, oh the web frameworks, so many to choose from... server side, client side, GWT, etc, etc, just about to start that process and it looks pretty daunting trying to find the wood through the trees and trees of java based web frameworks. Oh for a one tool fits all in this area too :-) My $0.02 worth.

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] What is the future for Delphi programmer?
But Google's phone just begin entering into the market. The 'Google Phone' has been around for quite a while now (I have had one for about a year... has not really been pushed in New Zealand)...

Re: [DUG] A change in upgrade policy coming from Embarcadero
To add to the language debate... We are now doing more Java stuff... Have to say I enjoy the IDE (Eclipse) more than Delphi's (2007), and I just seem to 'like' the language better. Have done a couple of small web related things, and also a couple of small (just to try it out) applications using SWT (this is the framework that Eclipse is built on, it uses native controls on Mac, Windows and Linux, making the applications look more native on each platform... and they do). Definitely a reasonable learning curve (and I have still lots to learn... just getting started really), and the applications are reasonably trivial, but it has worked OK so far. The Java run time environment also seems a fair bit lighter than the .net frameworks... though I have no idea on the provided total functionality of each, and for the applications I am involved with, I don't need to worry about deployment so much anyway.

[DUG]: Timing Resolutions
Hi all, I have just had someone ask me about timing resolution in Delphi. I understand that TDateTime can record milliseconds, but I am not sure to what level... also I have seen the TTimeStamp routing for storing time in more detail. I see that you can set a TTimer in milliseconds, but how low can you go??? I have heard 50 milliseconds, is that correct. I have also had a look at GetTickCount... that seems to go up in 10 millisecond intervals. Any info, or pointers to functions would be great.

What are you trying to do?? Myles. Hi Myles, The application was for controlling a robotic arm... I believe the application used to count pulses (from something) as the arm moved but this was proving unreliable as a pulse or two was getting missed. The application would need to time the movement of the arm... I think they where also looking at a PLC to do the counting and return the counts to the PC, that was another option.

RE: [DUG]: ISAPI and Thread Safeness
That is what I thought also... but it doesn't seem to... (unless the following can be otherwise explained). I found that when converting a CGI app to an ISAPI app I had some unexpected errors... for example, I was setting the name of an HTML file as follows: proPurOrdForm.HTMLFile := Somestuff + proPurOrdForm.HTMLFile; Since proPurOrdForm (a page producer) is on the TWebModule I would have thought it would get created and initialised for each web request... but it definitely doesn't... or at lease the proPurOrdForm.HTMLFile property gets longer and longer each time you visit the related page. I have found similar problems with other controls on the Web Module form (eg SQL statements in TQuery) which lead me to believe that a new instance of the Web Module is NOT created for each web request... I could not explain what was happening any other way... perhaps someone else can??

So the only area that you need to worry about threading is if you have any global objects outside of the TWebModule.

You will still have problems if you havnt locked the list while one thread is reading its contents, and the other thread is updating. Lots of delphi thread code that ive seen fix this by always locking a ThreadList before a read, but this seems ineffecient.

RE: [DUG]: Exception Handling (Delphi 5)
From my experience, the problem occurs if you have used the AppEvent component and then removed it, leaving the AppEvents (or what ever the unit name is for this component) in the uses clause. I also had one occasion where exceptions where still 'disappearing' and I searched hi and low for the AppEvents unit and couldn't find it. Just popping the AppEvents component on the form (and not even using it) fixed both problems... But if you have the unit and not the component, try removing it first.

RE: [DUG]: OK I've heard enough
Last time when Delphi 5 was released, I could not justify going to the Enterprise version... so we went with the Pro version (4 licenses) and purchased the ADO add-on and a few other third party tools... That has worked fine for us... so the main question is do you (or I !!) need the Enterprise version or will the Pro version do. If you look at the product matrix, for sure all (or most) of the 'New' features are in the Enterprise version and not the Pro. Now I don't yet know what all these 'New' things really are... maybe they are definitely needed by the greater majority (in which case they shouldn't be in the 'Enterprise' version), maybe they can be purchased separately, maybe there are cheaper and better third party add-ons that can be used with the Pro version that will do the same thing (but cheaper)... lots of maybes... And a final maybe... maybe we just need to wait for a couple of weeks and see how things settle down, see if more info becomes available as to what really is 'New' and what really is in the Enterprise version and available in no other way... I am sure hoping that we don't need to purchase the Enterprise version... that is one thing I can say! Also, an interesting side note to do with market share or future market share... Down here in little old Hamilton, a friend of mine was keen to go to a Delphi course at Tech... the course ended up been cancelled due to not enough interest/registrations, so they decided to do a Java course instead... that course ended up been jam-packed... It doesn't seem like a good sign if there are hardly any people wanting to learn Delphi, and those that do, can't (well... not at a Tech course in Hamilton anyway...)

Delphi is considered in corporates as a weird language - excellent by all reports, but weird. Often too weird to consider unless there is a contract Pro around to do some selling. How many times have I heard IT managers and IS Directors stating that they can deliver real state of the art, object oriented, multi-tier, corporate critical applications with a real Language like Microsoft Access or Microsoft Visual Basic. I have seen entire in-house development structures for corporates based on Microsoft Access - Hell, I've been to a few Microsoft mornings where they talk new buzzwords sprinkled with the words VB or Access and all the corporate people go away glassy eyed. If Borland doesn't want my business, I'm certain Microsoft does. Reality: I'm dreading going back to see a particular client in the morning who I convinced to purchase Delphi 5 for their junior programmer I'm training up. Convincing the guy to part with many thousands to get into Delphi 5 was like pulling teeth, I was there when he heard the price and he took a lot of convincing. If he has heard about the $5.5K to upgrade - something he will want to do as his junior and I support a lot of his web developed apps and Delphi 6 gives a large enhancement to that - If he's heard about the upgrade prices, my name in this town is going to be something not worth repeating. Either Borland has to do something and double quick, or it looses NZ developers in droves. Most will probably be like myself and will still carry on for a few years with their older versions on current developments, but any new work will be done with some other tool. I have already begun the search for that tool - probably Microsoft owned. BTW: This discussion used to be read by Borland Aus. and topical issues like this one were reported back to the States. Is this still the case? otherwise, it's about time one of us sent all these emails to Borland USA.

Hi all, Just have a query about how people generally go about using ISAPI apps (or CGI for that matter) and dealing with a number of database records and showing only a few at a time. For example, say the user queries the DB and has a result set of say 100 records and you only want to show 10 records at a time... Without knowing too much about this stuff, my first thought would be to have a hidden field or a URL parameter that holds the current record or page, and have this passed back to the CGI or ISAPI app when the user clicks forward or back. Now since ISAPI and CGI apps are stateless... do developers actually rerun the previous query and, if looking at the 3rd page say, then go forward 21 recs and start showing the next 10 records from there??? My question is, first, is this how people do it, and secondly, what if a DB user adds or deletes records in the mean time, the records shown from the CGI or ISAPI app could then have duplicates or miss out records etc... Any info appreciated Regards Colin ## Attention: The information in this email and in any attachments is confidential.

[DUG]: Installing Delphi on Win 2000
Hi, One of our guys is trying to get Delphi 5 Pro going on Windows 2000... He can install it successfully as an Admin and that is fine... For his day to day operations however, he logs in under a normal user account. With NT it was just a matter of re-running the install and choosing the registry only setting, this then set up Delphi for the new user name. However... with Win 2000 we have errors coming up about Uninstall shield being in use and setup cannot continue... Anyone have any ideas?? (He could just always log in as an Administrator... but his PC is not really in a secure location... etc etc) Regards Colin ## Attention: The information in this email and in any attachments is confidential.

[DUG]: Basic HTML/Delphi Question
Hi all... We are just starting to play with HTML and Delphi... thanks to those who gave references to tutorial sites!! I have a question... say I have an HTML file and I want to include the output from a Delphi CGI or ISAPI app in the middle of it... Is this possible... I can see 2 approaches. One: Build the whole html file from scratch in Delphi (possibly using the page producer object and replace the HTML tags). Tested this method and it works. Two: Have the output of the Delphi CGI or ISAPI app appear in the middle of the HTML file. This seems more elegant (especially if I want to use the same Delphi app in several different web pages) but I am not quite sure if it is possible or easy... For example, something like the image tag: ... Lots of HTML stuff including top menus etc... img src="file:///SomePictureFile.jpg" !-- and now the output of my Delphi app, eg. a table that could be used in lots of different pages -- html src="MyDelphiApp.dll/Whatever" !-- or some real tag that will allow me to include other html -- ... Lots more HTML stuff at the end of the doc Any info appreciated... ps. I have searched (and searched) for a tag that will allow me to include other HTML files but haven't found one...

RE: RE: Re: RE: [DUG]: Creating PChars
Funny you should mention that!! I am just looking at DeviceCapabilties now (one of the reasons for asking the PChar question) and I found that for some reason, sometimes the DeviceCapabilties function fails (i.e. returns -1). If you call it again after failing (which should be fine from what I can tell) in Delphi you go straight to the CPU window (it doesn't crash (usually, i.e. sometimes it does), just goes to the CPU window).. I have now found that what I was trying to do has already been done by Report Builder (which we use), so I just use their functions... haven't looked into it... but when returning info about a printer... for the ones that my code returns a -1 for, the Report Builder code works but it just takes a second or 2 longer... interesting...

Obviously you have to watch your step when using it, but if I'd had the number of problems that (I infer) you've had with it, then I'd suspect that that there was a corrupt version of borlandmm.dll being propagated around.

I think you will find IBX faster than via ADO, just due to less software layers being used and also IBX talks directly to the Interbase server, compared to ADO having to use ODBC to talk to the IB server. If using ADO you will need to install the Interbase ODBC driver on the client machines and configure the ODBC setup.

[DUG]: Strings and Win API calls...
Hi all,
I am just wondering exactly how one should go about passing strings in
structures to API calls...
I have been mucking around with MAPI stuff and come across the following
when dealing with attachments:
if Attachments.Count 0 then
GetMem(PtrMapiFileDescs, Attachments.Count * SizeOf(MapiFileDesc));
for i := 0 to Attachments.Count - 1 do
with PtrMapiFileDescs^[i] do begin
ulReserved := 0;
flFlags := 0;
nPosition:= $;
lpszPathName := PChar(Attachments[i]); {Attachments is a TStrings
object}
lpszFileName := nil;
lpFileType := nil;
end;
Now the above works when there is only 1 attachment, but if there are 2 then
the end of the filename of the first one gets screwed up by the writing of
the second. I can't really see why this occurs...
If I explicitly create a PChar and allocate space for it and assign the
attachment string to it, it all works fine...
Just more work involved making sure that you latter free the space assigned
to all the strings for each attachment...
Just wondering why the first method doesn't work for multiple attachments.
Regards
Colin

[DUG]: Delphi 5 Bug...
Yip, I think I found one already... It is to do with the OnContextPopup event which has been newly introduced... In our app we used to look for right clicks and Shift-F10 keyboard combinations to popup context menus for List view items much like explorer... We didn't respond to the new keyboard key yet, so I thought, Ok, not much code changing required to get it to work with all forms of Context Menu generation (as explained in the help file)... Great! The help file says: type TContextPopupEvent = procedure(Sender: TObject; MousePos: TPoint, var Handled: Boolean) of object; Description Sender is the control for which the user requested a popup menu. MousePos indicates the position of the mouse, in client coordinates, when the user clicked the right mouse button. If the user did not use a right click to invoke the popup (for example, if the event occurs in response to keyboard input), MousePos is (-1,-1). In particular, the problem is with the MousePos = (-1, -1) bit... it is not True, so it makes it hard to determine when you are responding to keyboard input and when you are responding to Mouse input (important when you are trying to identify which item the user wants the context menu to pop up for). Also in testing this, I used a ShowMessage(ListItem.Caption) to show which item the context menu was for... This also had another strange behaviour in that hitting Enter to close the MessageBox didn't... It brought up the Move/Close menu for the Message Box!! Sorry to bore you with the details, just thought some might be interested... and as the new Context Menu stuff stops my old code from working I shall have to find a new way of doing things... Sigh...

I must admit I strongly dislike (not quite hate!) using Delphi 3 after using Delphi 4.

The client-server (or Enterprise) upgrade price is steep!! Though, I guess if you are doing Enterprise development it would be worth the price. This time round (for the mean time anyway) we have gone for D5 Prof with the add on products, if we get into WEB development or need any of the other Enterprise stuff we will then look at purchasing the Enterprise addition.
