    // Create a simple combo box with two entries:
    // The first parameter is the id of the combo box.
    // The third parameter is the width of the combo box in pixels.
    // The fourth parameter is the display label of the combo box.
    // The fifth parameter is the index of the small image of the combo box.
    CMFCRibbonComboBox *pComboSimple = new CMFCRibbonComboBox(-1, FALSE, -1, 0, -1);

    pComboSimple->AddItem(_T("Hi!"));
    pComboSimple->AddItem(_T("Hello!"));
    pComboSimple->SelectItem(0);

    // Add combo button to "Favorites" panel:
    // CMFCRibbonPanel* pPanelFavorites
    pPanelFavorites->Add(pComboSimple);
