>>There are many screen capture programs; Aqua Deskperience and Kleptomania to name but two very powerful ones. One partial solution is to test whether these apps are running and take appropiate action but even then it will not stop a determined user, especially if your VFP app itself is not protected and/or the tables where the text may have come from. Your problem is much bigger then stopping the text from being copied off the screen :)

Is your exe protected against products like ReFox and Notepad?
