VB6 crashes after build

Question

Visual Basic 6 is crashing after a new build of my program. Whenever I Start (F5 or Ctrl-F5) my program after making changes to the code, VB6 crashes with the following message:

An unhandled win32 exception occured in VB6.EXE [XXXX].

I can't make any pattern out of XXXX. It's been 5168, 5012, 1488, etc; it changes every crash.

The JIT debugger then offers to let me debug VB6 in VS2010 (which shows nothing but a bunch of disassembly.) If I say no, VB6 shuts down. I can then open and Start my program immediately, and it runs just fine; my changes from before the crash were saved. Alternatively, I can make changes, save them, exit VB6, restart VB6, then run them without a problem. But it seems like as soon as I make any changes, a "crash" flag is set, and if I try and build it before restarting VB6, it simply dies.

I'm only having this problem with specific projects. Most projects work completely normally. It's just this one, and it's branch, that both act in the same manner.

Does anyone have any clue what's going on? Obviously, saving works. And building works. And running works. They just don't seem to work together.

I reinstalled VB6 to no avail.

Answer 1

Reinstall VB6, delete the workspace files and then create a new project adding in all your current code files. Then go out and get a job where they use a modern SDK :)

Answer 2

Since you're asking for any clues, possible clues may include:

• The surprises VB6 experiences when run on Vista/7. Try running elevated/remove elevation.
• Same, but applied to a third party ActiveX control you're using.
• Not having the Service Pack 6 installed. Install it.
• Subclassing issues. Make sure your subclassing, if any, is actually correct.
• Whatever problems you'll never figure out. Try reinstalling.
