ASP.NET/ActiveX/Silverlight Screen Capture

I need a way to capture the screen within a web application in any way possible. Is there such a way without installing other tools like SnagIt? Can I use Win32 DllImports within an ActiveX component and do it that way?

Thanks in advance!

Solution

Here is some code that will take a screen shoot of your silverlight app. and then you can send it or what ever :-)

Just create a silverlight project (with normal mainpage etc. and replace with this.

works in both 3.0 and 4.0 (havent tried 2.0 and lower)

Hope i helps Regards ReLoad
