Collision Detection help!

As I've said before, I'm really REALLY new at this, so I have a quiestion or sixteen to ask. :D

1) What the !@$!@$! is a DC? Where can i learn to use it?
2) Okay, so I learned how to do KeyDown, KeyUp and KeyPress today. Using two images I put on a form (imgIMageToMove and imgBullseye) how do I do collision detection to tell when they slam into each other?
3) BitBlt: What is it and how do I use it?
4) Who thinks that small, fluffy sheep should be shot out of cannons? ;-)

Thanks for the help, guys and gals.

That which does not kill me, has made it's last mistake!

1) Device Context (handle = hDC), it's like a handle to the graphical representation of something (such as hWnd is a window handle).

2) Use the Intersect Rect API, give it the top, left, top + height and left + width of a picturebox to a rect structure, and the same for another picturebox. Will return 0 if they don't touch.

4) YES! Someone finally agrees with me :D
