I have a problem with our application, which has a state in full screen mode. If user press the alt key (for alt tab for example), the menu appears on the top of the screen. The FullScreenState sample has the same problem. How can I prevent this ?

The menu bar window does not know if its parent frame window is in the full screen mode or not. It acts exactly the same in both modes. If you want to make the menu bar ignoring the ALT key in the full screen mode, then you should use the following menu bar class:

class CYourMenuBar : public CExtMenuControlBar
      virtual BOOL TranslateMainFrameMessage(MSG* pMsg)
            if(         CExtPopupMenuWnd::g_bFullScreenMode
                  &&    WM_KEYFIRST <= pMsg->message && pMsg->message <= WM_KEYLAST
                  &&    pMsg->wParam == VK_MENU
                  return FALSE;
            return CExtMenuControlBar::TranslateMainFrameMessage(MSG* pMsg);
Please note menu commands in menus displayed by the menu bar’s buttons are typically contain all the commands available in application. So, it’s recommended to make the menu bar available any time.
