paint a circle on top of any component

Hi.
I want to paint a filled-in circle on the form that will appear over top of anything else. So, if I paint a circle at 300,300 with radius of 100, it will appear as a whole circle, regardless of what components are also located at that point on the screen. Also, how can I fill in that circle?


I guess twoways:
1) some sort of desktop window paintcircle technique
2) a pre-drawn circle bitmap that is bitblt copied to the form

I don't know which is right or how to do either.

Does anybody else here?
Thanks

Using GetDC(GetDesktopWindow), you can use a Circle API call to draw directly onto the screen.
