HELP! HELP! My apps works fine. I get AV's if recompile and run.

[ocornwall]

I have an app which has been working for months. I recently attempted to install Delphi 5.0 Update Patch #1 (UP1) and I recently tried downloaded CoolTray, PSQRFilter from this site.

I have an old copy of my code which works fine. I run the source code in Delphi 5.0 and It works well. If I make any changes and recompile I get Access Violation whenever the application create any form other than the main form. I have removed all of the recent installs (CoolTray, PsQRFilter and UP1) and I still have the same problem.

Why would I get AV's when any form other then the Main Form is created. I have tried manually creating the forms with the same problem.

Any ideas?

Thanks

I have no idea.
When I have some AV's, I close Delphi, and restarts it. If don't works fine, reboot the computer... Finally, if anything works, uninstall and reinstall Delphi.
Sorry.

I had the same problem after upgrading to Delphi 5.1

I just uninstalled Delphi, and then re-installed 5.0 without applying the 5.1 patch.

==================================================
Possible Problem #1:
==================================================
Are you creating the form instances correctly as in the following format:

var
MyForm : TForm // declair the form variable
Begin
MyForm := TForm.Create(nil); // create the instance
End;

And when destroying the form you are using
MyForm.Close;

Are you destroying the forms when they are no longer needed?
If you dont there will be a memory leak.

==================================================
Possible Problem #2:
==================================================
Sometimes when you install custom components you download
from this site, or others, they include examples with them.
And sometimes the examples are named like delphi default
project names, ie: PROJECT1, Unit1.pas, Unit2.pas etc. If they are names UNIT1.pas or PROJECT1 and you these files exist within the delphi envirment path this can cause a load of problems for delphi and can be hard to track down. Make sure that no project has a file UNIT1.PAS in any of the delphi envirment paths... ie: Lib, or Bin subfolders..

I dont know if any of these will help, but might be worth a try.
