how to capture part of form in a bitmap

[dawn]

Hi,

I'm trying to capture a part of an active form into a bitmap. So the
coordinates for the part that needs to be captured should be relative to the
window, because the window might move on the desktop.
Secondly I'd like to compare this to an image I have already stored on my
computer.
Is there any way I could do this in c#. A piece of source code would be
greatly appreciated.

Thanks.

There is an article in the GDI+ FAQ that explains how to do this.
