    Menubar / Toolbar problem

    Hi .. I need to activate and deactivate Menubar and Toolbar time to time.
    I have written code :

    CWnd * pFrame = (CWnd *)AfxGetMainWnd();
    CMenu * menu = pFrame->GetMenu();

    for (int mq = 0;mq < menu->GetMenuItemCount();mq++)
    menu->EnableMenuItem(mq,MF_BYPOSITION|MF_GRAYED);

    pFrame->DrawMenuBar();

    I just change attibute MF_GRAYED to MF_ENABLED as required.

    This works fine with MenuBar but there is a problem with ToolBar .

    Toolbar Enable/Disable doesnot happen properly.

    PL Guide

    Thanking you ...

    There is an ON_UPDATE_COMMAND_UI mechanism in MFC to enable/disable menu items as well as toolbar buttons

    Re: Menubar / Toolbar problem

    Victor Sir , I am using ON_UPDATECOMMAND_UI to Enable/Disable Menu Items .

    Here , I have a Replay Old Files option in my software. While Replaying the old file , I wish to disable the whole MenuBar and ToolBar . Once Replay is over , the user presses Escape and he is back to the routine software.

    So I call DrawMenuBar function with attributes MF_GRAYED and MF_ENABLED.

    Sometimes this works fine.

    Sometimes , the MenuBar is active but Toolbar remains inactive.(Though Toolbar IDS are same as MenuItem ids). Sometimes the MenuBar is disabled but Toolbar remains enabled.

    So I am confused.

    PL guide.Thanking you ...

    How did you that?
    Both CWnd:: DrawMenuBar and :: DrawMenuBar functions take no arguments.

    ovidiucucu sir , I set Menu Item property to either MF_ENABLED or MF_GRAYED , and then call DrawMenuBar ..

    Sometimes It takes proper attributes and sometimes it does not ..

    So I am confused
