I'm using an old script engine that's no longer supported by its creators, and having some trouble with memory leaks. It uses a function written in ASM to call from scripts into Delphi functions, and returns the result as an integer then passes that integer as an untyped parameter to another procedure that translates it into the correct...
I'm using Delphi (7-2010) and trying to figure out a good way to handle exceptions while freeing forms of an application. The application has several forms that are owned by the Application object. When the user logs out, I need to free all of the existing forms so no user state is maintained and then show the login dialog for the next...

I used iso-8859-2 encoding in the body, and this encode the subject, and the email addresses to (the sender address is contains name). I though...
I'm trying to create a Gecko 2.0-compatible DLL in Delphi. Previously (pre-Gecko 2.0) the DLL needed to export a NSGetModule() function. This worked flawlessly. Starting with Firefox 4, my DLL is getting loaded (I have verified this though a breakpoint in my initialization section), but my NSGetModule() function does not get called any...
Hi Ray, Did you ever solve the following problem? I am experiencing it. I'm running Windows 7 x64. "I was able to find a Delphi 2007 installer that had the December 2007 update.

Can't seem to find this kind of tool anyway I search - maybe that's because one...

The reason I ask this is widows do not support a good method to communicate between processes. So I want to create a DLL for a communications point between windows processes. A thread is owned by a process and cannot be given to another process. Each thread has a stack of its own. If a DLL is loaded (loadlibray) and a DLL function is ca...
