Debug not working

aztec,

> ... I can't debug anything

Anything as "anything in my current app" or "any project at all" ?

If your answer is "only my current app" then try this:

1) delete any *.dcu, *.dsm, *.exe file in your project folder

2) Be sure *all* lines in your source files are terminated properly (CR/LF), especially if you copy/pasted some parts of the code from somewhere other then Delphi editor

3) Turn all debugging related options in your Project->Options->Compiler tab on

4) Recompile your app

In addition to Cynna's advice:

If the breakpoint remains valid during execution (the line is still red) then it's possible that execution never reaches the line.
Sometimes it's as simple as this...

Another idea:
Make sure you have 'Integrated debugging' option turned on in Tools\Debugger options dialog.

Hello Cynna..
   I tried another of my apps (a small one) and the debugging worked fine within that on. It is just within this app that it doesn't. And get this: My app uses several different screens or tabs. Debugging will work fine in one tab/screen, but won't in another tab/screen!
  I followed your suggestions above (1) (3) and (4). For (2), I don't know how to check if there's a CR/LF at the end of each line. Just rename my .pas file to .txt and open in up in NotePad perhaps?

TOndrej: Yes, I am sure that execution reaches this point, but it still blows right by my breakpoint. And yes, "Integrated Debugging" was turned on.

Here's something else that's weird that might help you - you know how when you build your project, it puts all the little dots to the left of each line of executable code? OK, it does that all right, but when I do an F12 to show my form, and I go to another tab/screen via the Object Inspector, then double click on a button on that specific form (which takes me to that event handler), then all the dots on the left are gone... all the way down through my app's code!

Something very weird going on here...

I think I have isolated the problem....things debug fine up until a certain line in my code. That line is:

fromfile.Destroy;

I am using a 3rd party component called TGPHugeFile, suggested to me by another expert. The component itself seems to be working ok, but it seems to be messing up the debugging. In the procedure containing this ine, I open up a TGPHugeFile like so:

fromfile:=TGpHugeFileStream.Create(infilestr, accRead);

...then I read from it like so:

ibytesOK:=fromfile.Read(buf, bigchunksize);

then finally I close it up with the fromfile.destroy statement as mentioned above. Everything debugs fine until I hit this Destroy statement.


I can step while in debug, right up to this line, when I try to step OVER it, it will go into code of the GPHugeF unit....and from there on, I lose debugging control over my project.

Hope someone can help!

Thanks
