Owner-drawn menus
Author
I have a problem with my owner drawn menus. I’ve made the menus myself. I’ve set the owner-draw flags and overridden the WM_MEASUREITEM and WM_DRAWITEM messages.
My problem is I still have left-over padding from the menus. My guess is I’m not calculating the menu size right. I’m calculating the menu size vie character size * string size.
This is my code for WM_MEASUREITEM
See MSDN, about halfway down the page, for detailed info and sample code relating to owner-drawn menus. One error I see is that you're getting a DC in that function but never releasing it. I doubt that's the problem, but it is a memory leak (at least until your program terminates). Put in a call to ReleaseDC(hDC) at the end of the function.
How come you're adding 20 and 4 to the item dimensions? In the sample code at MSDN, they don't do that. That's probably what's giving you extra padding.

Yes, I forgot to release the DC. I was adding those numbers to the item dimensions so that their would be room for the icon.
[EDIT] Removeingthe numbers doesn't do anything except cram things together.
