[Peter P Stephensen]

Hi all,

Very short version:

    a lot of code...
  
    msgbox "test"
    ' Here it GPF !!!      
exit function

When I run the program it showes the msgbox and then it GPF!
Anybody seen that before?

Hi Peter,

I have experienced something very similar to what you describe.
In the end, I was able to trace the problem to corrupted memory.
I was writing well past the bounds of my arrays, but apparantly
within the memory space alloted to my app. Therefore, I didn't
get any error messages right away. But when I attempted to use
a MSGBOX or in some cases just any string function (like FORMAT$())
I would get a GPF.

It drove me bonkers for a while. Difficult to find the unexpected....

Without more specific source it is hard to say what it is.
It could be that your winamp player is playing the wrong song...

However, seriously speaking, I have had issues with killing objects (OR Not destroying them), in the WM_CLOSE or WM_QUERYENDSESSION and found that if I have to close mutexes or files sometimes it is best to do right after dialog show etc.

Ie,

Winmain:
Dialog Show hDlg Call DialogProc
Close hFile1
Close hTcp
Cosehandle hMutex
KillTimer hTimer etc
'You get the point....
End Function
