Is your edit box its own class?
If it is you can just trap for WM_KEYUP

If not then I think you can use the edit box's handle and ::KeyUp()

Sorry never done this before so I am not real sure. I am sorry to say MFC programming is kinda a bad word on the this board. I think I am one of a few people, other than yourself, that ask MFC questions and does MFC programming. I have asked a ton of MFC question on

http://codeguru.earthweb.com/bbs/wt/...=list&Board=vc

and gotten a lot of answers. Infact I have stopped asking MFC questions here because they were never answered.
