Calling MFC methods

MFC dialog

The demo application MfcTutorial contains an example of an MFC dialog, CLanguageDialog. The example code below shows how to call this dialog when the add-in is opened.

BOOL CMfcTutorialApp::OnXllOpenEx()
    // Create an instance of CExcelWnd
    CExcelWnd wndParent;

    // Create a dialog whose parent is Excel's application window
    CLanguageDialog lang(&wndParent);

    // Show the dialog and fail if the user cancels 
    if (lang.DoModal() != IDOK)
        return FALSE;

    // Read the user's input from the dialog
    m_nLanguage = lang.m_nLanguage;
    return TRUE;
