> Is there any way I can get the MenuItemID's of the parent MenuID?

Its pretty simple. Just get the count of items, then walk through
grabbing each ID. I just whipped this up in GMail, it might not work
entirely:

global function getMenuItemIDs( atom MenuID )
-- MenuID is the parent menu handle

    integer count
    sequence IDs
    atom ID

    count = c_func( xGetMenuItemCount, {MenuID} )
    if count = -1 then
        return {}
    end if

    IDs = {}

    for i = 0 to count-1 do  -- zero-based index
        IDs &= c_func( xGetMenuItemID, {MenuID, i} )
    end if

    return IDs
end function

> I get mID as a number which fails in xGetMenuItemID with "type_check fail=
ure, mID is 4294967295" error.

That's because its too big to be an integer. You need to declare mID
as an atom. Most Windows "handles" need to be atoms.

BOOL RemoveMenu(
    HMENU  hmenu,=09// handle of menu
    UINT  uItem,=09// menu item identifier or position
    UINT  fuFlags=09// menu item flag
   );

They're Windows API functions, and they don't start with 'x', most of
us use that to separate them from the actual functions used to wrap
them. Download the Windows API documentation here: (link from the
