Dear All.

My customer is making a program with security function
and they have to prevent this application's screen
capturing or whole screen capturing from "Print Scrn" key
and other screen capturing programs.

I'm not on this alias. Please e-mail me directly.

How could they do?
Thank you for your help.

Best regards.

There is some feature in Windows through
display hardware that makes it possible to
prevent screen capture of a window. In the
captured screen the windows appears blacked
out. Sorry but I don't exactly remember this. Search
on net, you will definietly find it.

HTH,

you could write a little tool which polls the clipboard and kills every
print-screen like content if it finds some

Hi,

I believe that something like this is possible through DirectX.

I definitely agree with Kirk Ferdmann:
"First of all there is no need to include all those NGs in cross-posting.
Secondly it usually considerd inpolite to ask a question in a NG and request
the answer to be emailed to you - there are other people who can potentially
benefit from reading it."

Regards,
Filip
