Disabling::Popup Menu

Code:

---

IDR_MYMENU MENU
BEGIN
    POPUP "&File"
    BEGIN
        MENUITEM "E&xit", ID_FILE_EXIT
    END

    POPUP "&Stuff"
    BEGIN
        MENUITEM "&Go", ID_STUFF_GO
        MENUITEM "G&o somewhere else", 0, GRAYED
    END
END

---

I have the menu above. I can disable each item in the popup based on the ID but I can't grayout the the main popup area. In this case the &File.
Is their a way to disable it, without knowing its ID?

Does this help??
Unchecking a popup menu

@shekar: already check that, but not what Im looking for.

Something like:

Code:

---

CMenu* pMenu = AfxGetMainWnd()->GetMenu();
if(pMenu != NULL)
  pMenu->EnableMenuItem(1, MF_BYPOSITION | MF_GRAYED); // disable second (with index '1') menu

---

And please don't miss this point:

When you change a window menu, the menu bar is not immediately updated. To force the update, call DrawMenuBar.

Good point, Igor!
(Although in my small and fast test the menu item was disabled without DrawMenuBar call, it is still required if some of menus/submenus was removed or added or the whole menu bar).
