Since your original post was about Owner Drawn Menus, here's some code regarding such to get you going. Sorry if it isn't the cleanest... just started C++ a couple of days ago... built it from DevC++ so there's the comments in there...
There's a cheap resource file, and a skeleton for the WM_DRAWITEM and WM_MEASUREITEM messages.
The basic idea is this: get the menu. Set the first item as owner-drawn. Then set it to 400 pixels wide. When DrawItem is called, draw a rectangle (green if selected) and then draw some text over top.
If you wanna add image lists or whatever later it's easy enough to do.
