Unhandled exception when ending a program |
When I try to end my program, which is written in VC++6.0 and runs on WinXP,
I get an error message "Unhandled exception with my.exe (NTDLL.DLL). Access
violation." My code is like this:
case WM_DESTROY:
{
// tell the rendering loop to terminate itself
EnterCriticalSection(&csThreadSafe);
rsRenderData.bTerminate = TRUE;
rsRenderData.bModifyFlag = TRUE;
LeaveCriticalSection(&csThreadSafe);
WaitForSingleObject(hThreadHandle, 5000);
DeleteCriticalSection(&csThreadSafe);
delete pScene;
glDeleteLists(nFontList, 128);
// shut down OpenGL Rendering context
wglMakeCurrent(hDC, 0);
wglDeleteContext(hRC);
ReleaseDC(hWnd, hDC);
PostQuitMessage(0);
}
Can anyone give me some suggestion what might be the problem? Thanks.

No, not nearly enough information. In any case this is a C++ group not a
windows programming group.
I suggest that you try a debugger, if that doesn't help then try removing
code until you eliminate the problem, that should give you a clue as to
which line is causing the problem. If you are still stuck ask in a Windows
programming group such as comp.os.ms-windows.programmer.win32.

The first problem is that you're asking about this in the wrong place.
We only discuss ISO standard C++ here, as indicated in:
http://www.slack.net/~shiva/welcome.txt
The place to ask about Windows programming issues is newsgroup
comp.os.ms-windows.programmer.win32
If it turns out the problem is with the OpenGL stuff, try:
comp.graphics.api.opengl
