Reading color from screen

Using Visual Basic 5, how can I find out what color is on
the screen at a certain coordinate, but not on a form that is part of my program, just at any given coordinate?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You need to know few api calls
GetDestopwindow: gives you the HWND of the desktop which is the screen.
GetDC: gives you the DC(a handle of a canvas) of the given HWND.
GetPixel: returns a colour of a point from the given DC.

If you know the DC of the current screen then you can use GetPixel(DesktopDC, X, Y) = a colour.

I really need to know how to set up these API
calls, because I've never worked with them before.
This would have been a more helpful answer if I
had previous experience in setting up these API
calls, which I don't.
