I have an IDR_MAINFRAME main menu in an SDI application. Is there any
way to disable a whole top level selection (and subordinates) based on a
condition?

Like, disable the Edit menu and all items under it if a document isn't
loaded?

I have done that with sub items using CView::OnUpdate() but there is no
ID number for the top level menu item, and I can't get Class Wiz to
create an OnUpdate method for it.

Or do I have to do it separately for each sub item underneath?

Thanks.

You use EnableMenuItem and reference menu bar items by _position_.

e.g.

CMenu * pMenu = GetMenu ();
if (pMenu)
  pMenu->EnableMenuItem (0, MF_GRAYED|MF_BYPOSITION);
DrawMenubar();

Will gray out the leftmost item on your window's menubar.
