Probably some bug in your code somewhere because MFC is quite a "cross-windows" library. The bug is definitely not in the code you shared.

Your problem statment is unclear. Did you build/run it on Windows XP *AND* on Windows 7.0 or did you simply build it on Windows XP and move the binary to Windows 7 and then it doesn't work? If it's the latter, chances are you have some libraries missing from the Windows 7 machine. For example, are your building / moving the DEBUG build or the RELEASE build?

First, when replying to someone, use the "Repky" button on the right side of their message. Since you didn't do that, I didn't get an e-mail saying you replied and you might have waited forever for a reply.

Secondly, did you also run the release build on the XP machine? Where is your development done, XP or Win 7 or BOTH? You need to provide precise answers otherwise we do not know what environments are working / failing.
