I'm looking for some Visual Basic code that will stop users from
taking screen shot of my application.  How is something like that
done?  Thanks for your time.  Have a great one.

The vbVision website provides a public domain Visual Basic project
that claims to prevent the screen image of a VB form from being
captured to the clipboard.  I have not been able to test it myself,
but the code looks like it should work.

The software is described at
http://www.mvps.org/vbvision/Sample_Projects.htm , look for the No
Clipboard Demo about halfway down the page.  The project files are
available at http://www.mvps.org/vbvision/_samples/No_Clipboard_Demo.zip

However, please note that some graphics software (such as Paintshop
Pro) will still be able to capture screen shots even if you have
disabled PrintScreen.

I hope this answers your question.  If not, please request an answer
clarification before you proceed to rate it.

Search term used on Google:
prevent "print screen" OR prtscr clipboard "visual basic" OR vb

You could probably make it difficult for people to make screenshots by
using the PrintScreen (PrtScr) button, but you could never stop
someone from photographing the screen with a camera.  It is also
possible to tap the signal that runs through the video card to get a
perfect digital copy of the screen image.

I's only concerned with printscreen and the like.  Thank you.
