Found answers myself!
The easiest way to do this is to activate the window and to send an
Alt-PrtScr keypress event. After that you can simply read the captured image
from the clipboard. How to send a printscreen or alt-printscreen is explained
by me in this thread on EE on using SendKeys.

To capture the screenshot of the whole screen or a particular are, this will
help

Once you obtain the handle to the application, find its location and
dimensions and capture the image of that area.

How can I capture (an image) of the contents of Application #A window ....
from Application #B. Let's say there are two, totally separate, independent
applications running, #A & #B. From Application #B, I want to locate
Application #A, then locate #A's currently active desktop window and capture
an image of whatever's being shown.
Application #A - I have no idea what programming method/tools were used to
create this app, but is runs in XP.
Application #B (the imager capturer) - will be written using the .NET CLR
and either C# or VB.NET in a Winforms Applications.
Any pointers or help appreciated.
