Yes. I could find a good code for copying an area from the screen into a bitmap . Still the second part of my question. How Can I within my wpf application go to any window (not necessary in my project) and <br />
select a rectanglar area &nbsp;and retrieve the the four coordinations of this area in order to copy the image <br />
inside it. &nbsp;<br />
Thanks!

I would like my Wpf c# application to be able to capture any rectanglar area on the screen as an image. the selection could be performed via a rectangle that the user can draw with the mouse.<br />
The &nbsp;capturing of this area should be done while my application is transparent so I can have a visual access to other windows...<br />
Please help!
