Not calling ExitInstance

[Rob C]

I am using MFC in Visual Studio .NET 2003. When
investigating a memory leak, I discovered that my CWinApp
overridden ExitInstance method was not getting called at
the end of the execution. I know it did at one time and
then only thing significant that I did was move my project
from Visual Studio V6 to VS .NET 2003.

I set a breakpoint in the ExitInstance method and it never
breaks.

This is my definition in my CPP file:

int CCMSDesktopApp::ExitInstance()
{
// Release COM
CoUninitialize();

if (m_pListMgr)
{
delete m_pListMgr;
}

return CWinApp::ExitInstance();

}

In my h file I declare:

// Overrides
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CCMSDesktopApp)
public:
virtual BOOL InitInstance();
virtual int ExitInstance();
//}}AFX_VIRTUAL

Any ideas on what might be happening here?

Thanks,

-Rob

Is the application dialog-based? They always (usually?) exit directly
from InitInstance() and I have a vague recollection that ExitInstance()
isn't called if FALSE is returned from InitInstance().

You are correct that they exit directly from InitInstance. However, if you check
thrdcore.cpp (near line 116 in VS6 version) you will see that ExitInstance is always
called, even when InitInstance returns FALSE.

The app is an SDI app. The strange thing is that when I
build the app in VC V6, it calls ExitInstance. When I
build it in VS .NET, it does not call ExitInstance. It is
the same exact source code for both.

Then perhaps Microsoft changed the behavior. This is, of course, trivial to determine:
just read the MFC source code.

ExitInstance is called in CWinThread::PumpMessage. This is the only point of
normal return from the message loop.
Another call is in CFrameWnd::OnEndSession.
You're not calling exit() anywhere by any chance?
