// In a dialog-based MFC application, it appears that one cannot pop
// up a message box after displaying one or more dialog boxes
// (see also MFC KBase article #Q138681):

BOOL CMyWinApp::InitInstance()
{
        m_pMainWnd = NULL;      // needed to prevent WM_QUIT

        CMyDialog1 dlg1;
        dlg1.DoModal();         // succeeds

        CMyDialog2 dlg2;
        dlg2.DoModal();         // succeeds

        if ( ::MessageBox(NULL, "View results ?", "App",
                                        MB_ICONINFORMATION | MB_YESNO) == IDYES )
        {
                // the message box fails to display;
                // it flashes briefly and disappears
                // without accepting user input
                // the following code always executes:
                int x;
                x = 0;  // whatever
        }

// How can I force the message box to display?
