Re: AfxMessageBox returns immediately without displaying the box

Hi,

This is a pseudo code from InitInstance() of my dialog based app:

 if (cmdInfo.m_strAppName.IsEmpty()) {
   AfxMessageBox(IDS_SYNTAX, MB_OK | MB_ICONSTOP); // <= works fine!
   return FALSE;
 }

 try {
   /* ... */
   CMyDlg dlg;
   m_pMainWnd = &dlg;
   INT_PTR nResponse = dlg.DoModal();
   if (nResponse == IDOK) {

       /* ... */ // might throw CMyException

       } else if (nResponse == IDCANCEL) {
           // TODO: Place code here to handle when the dialog is
           // dismissed with Cancel
       }
   } catch (CMyException& e) {
       // Neither of the calls below will display the box
       //nResponse = AfxMessageBox(e.GetErrorMessage(), MB_OK |
MB_ICONSTOP);
       nResponse = ::MessageBox(NULL, L"Text", L"Caption", MB_OK |
MB_ICONSTOP);
   }

The problem is that whenever exception is thrown I could hear a beep but
the message box is not displayed. Both Afx.. and Win API functions return
immediately with ret code set to 1 (IDOK).

Could someone please give me some idea what might be causing that
behaviour?

Thanks,
Bogdan
