Retrieves the Menu or MenuBar object which has the specified handle.
Menu := MenuFromHandle(Handle)
Type: Integer
A value of Menu.Handle.
If the handle is not the Handle of a menu of this script, the function returns an empty string.
In AutoHotkey, Handle is a Win32 menu handle (HMENU). In Keysharp, menus have no Win32 menu, so a native menu handle, such as one received with the WM_INITMENUPOPUP message, is never recognized. See Win32 Menus.
