How to prevent PrtScn?
-
This isn't necessarily a C# question. Any ideas how to prevent PrtScn from doing it's thing? I know there's a variety of screen capture programs out there, but let's assume for the moment that the client's environment is sufficiently controlled that a third party screen capture app isn't an issue. But we do want to stop the built-in prtscn from working so that an unscrupulous client can't take screen shots of sensitive information. Marc MyXaml Advanced Unit Testing YAPO

i have an idea and i think it may help you ========================================== you can check all your open ports in your pc and then listen to them all and then refuse the connection request comes from any port this is the idea behind any firewall application i guess so .............. about the designing of this programmer is very easy to preform Thank you my brother....

How about a keyboard hook that gets loaded at system startup and swallows all PrintScreen keypresses? Regards Senthil _____________________________ My Blog | My Articles | WinMacro

i think he meant printscreen, not portscan... either that or im even more confusticated than i thought . :~ on the other hand, listening to open ports to stop a a printscreen sounds like an interesting challenge for masochists :((

I agree with Kumar. A keyboard hook will let you stop the PrintScreen key from ever reaching the system. I wrote up something similar in C++ a few years back to eat the Windows key. I also seem to remember hearing somewhere that if you change the Opacity of the form, even to 99%, PrintScreen won't see your form. Try it, see what happens. But the down side to this is that it might not work like this with all video drivers and versions of Windows, especially future versions. Ack! Forget I mentioned it!

PrintSCreen doesnt work on video overlay windows, maybe you can have a transparent overlay window, over sensitive data. Would make a nice article :) xacc-ide 0.0.15 now with C#, MSIL, C, XML, ASP.NET, Nemerle, MyXaml and HLSL coloring - Screenshots
