There are still tools such as SnagIt that can copy anything on the screen as a bitmap, even the online e-Books, and I imagine you could feed them through OCR to get the text.

HI all,
Check out the keyboard hook facility in the Windows API, as you may be able to disable the printscreen button (or any other key combination) while your app has focus.
I've seen it done by the people who have online e-Books, where you can read the book onscreen, but not print or copy it in any way.
cheers
Gary
