Print Screen Question

Subject:Print Screen Question

Does anybody know of an api for the Print Screen (to clipboard) feature?
I know how to emulate this using BitBlt but I want to know exactly how
the Print Screen works.

The reason I ask is that I have a application that's image [window] can
be captured using the Print Screen key but not in code with BitBlt. I've
tried a number of different Delphi capture programs that use BitBlt and
none of them can get an image of the application? The application is a
Apollo program that does an alpha blend of it's main form so it's
non-square with no title bar or border.
