It depends if you really mean all open windows or only those shown in the

But I would guess you need something using EnumWindows and a call-back.

I have a program I am trying to write but I am having some difficutly
figuring out how to get API to do the following...

Show me in multiple message boxes (MSGBOX) what windows are open (what

but can't seem to find anything to works the way I would hope it
would. Any help is much appreciated!

Thank you!
