Help on API function

[HazySmoke)345]

I remember seeing this somewhere - there's a Windows API function that converts the coordinates of a point on the window to the coordinates of the same point on the screen. I just can't recall the name of it!! Anyone knows?

I don't know the name of the function but...

Couldn't you just take the coordinates of that point and add it to the location of the form itself? That should give you the coordinates of the same point but relative to the screen.
