OnAppExit()

What is the default action for the Application exit? I tried creating a message map for OnAppExit to perform some checking and cleanup. Everything worked except the applicaiton did not exit. So, I added exit(0) to the end of the function. In debug mode, everything works fine but in release mode I get an exception and the program crashes. I disabled the function and message map and the program exists without any problem in release or debug. What should I call to terminate the application when overriding the AppExit()?


Thanks,

The CWinApp default handler does:


void CWinApp::OnAppExit()

{

// same as double-clicking on main window close box

ASSERT(m_pMainWnd != NULL);

m_pMainWnd->SendMessage(WM_CLOSE);

}


Explicitly calling this from your overridden handler should work fine, although I might like to suggest that you do your stuff in an override of CWinApp::ExitInstance() or the even the destructor of your Application object.

Are you calling the base class implementation at the end of your override?


void MyApp::OnAppExit()

{

// do cleanup

...

CWinApp::OnAppExit(); // call base class implementation

}

Do NOT use exit(0) from a Windows application
