I lost my example from the RPG script I was making (ages ago), but if you want to do it without the class, goto
MSDN and take a look at the"Remarks section".
So create a new menu (different var name obvoiusly), and then append a new item to the main menu, but pass the MF_POPUP param and pass it the handle to the new menu.
If that makes sense lol.
I think you have to finish the popup menu before "attaching" it to the main menu though.
