I have some really complicated legacy code I've been working on that crashes when collecting big chunks of data. I've been unable to find the exact reason for the crashes and am trying different ways to solve it or at least recover nicely. The last thing I did was enclose the crashing code in a try ... except cleanup(); end; just ...

In Delphi 2009 I'm finding that any time I use TThread.CurrentThread in an application, I'll get an error message like the following when the application closes: Exception EAccessViolation in module ntdll.dll at 0003DBBA. Access violation at address 7799DBBA in module 'ntdll.dll'. Write of address 00000014. Unless it's just my machin...
I know this is a long shot - but is there any way at all to get code folding into Delphi 7? I'm working on some .. "suboptimal" .. code. Sometimes I really need to fold bits away to grok a stupid-long procedure. Currently I'm pasting code into Notepad++, which works, but it would be nice to have it in the IDE. ...
I've been working on a project in Delphi 7 where I wanted to have forms inherit components from other forms. I was able to get this working, but came across the following issues (and I'm going to post the solutions to hopefully help others in the future): In the .pas file of a form, I would change the form to inherit from some other fo...

Now when you get sizeof(string) you get length(String) * sizeof(char) . Sizeof(char) currently being 2. What I am interested in is whether anyone knows of a way which on a character by character basis it ...
I use an activex component in my C# program that was created with Delphi. It works fine a lot of the time, but occasionally (sometimes frequently!) the component crashes with this exception: Exception EOSError (A call to an OS function failed)(0) which leaves the control in a somewhat unusable state until the program is restarted....
I can reset FPU's CTRL registers with this: http://support.microsoft.com/kb/326219 But how can I save current registers, and restore them later? It's from .net code.. What I'm doing, is from Delphi calling an .net dll as an COM module. Checking the CTRL registers in delphi yield one value, checking with controlfp in the .net code giv...

I've had my first go at writing a DLL in Delphi. So far so good. By using a typelib I've been able to pass Widestrings to and from the DLL without difficulty. What's curious at the moment is that I'm using VB6 as the testbed, and every time I run a test within the IDE, the program runs and then the IDE process suddenly disappears from m...
