Answer 1

Yes, Just as easy as capturing the full screen. You just use GetWindowDC() on the required window rather than GetDesktopWindow(), then BitBlt() from that to your target DC. You can also get the correct size by using GetWindowRect().

Note that this method also allows you to capture from hidden/covered windows where a full screenshot with a bounding rectangle doesn't.

See this question for some more details.
