Get visible part from a control

none

I have two windows. When i move the sencond form... i need to know if it`s hiting the button from the first form.
It`s not big deal... but... how can i know what part from my button it`s hiding behind another form (winamp for example)?

html example:

First window

X

my butt

winamp

second window

X

I know how to do this.... I don`t know how can i know the visible region from my button. If I`m over button... but the button it`s hiding behind other window... nothing will happens....
How can i know what part from my button it`s visible to user (and what part it`s hiding)?

A control's location within a form is expressed in client coordinates; in other words, relative to the top-left corner of the form's client area. You can convert client coordinates to screen coordinates using the Control.PointToScreen Method and then you will have universal location values.

If the button is in a different application then you will need to find the window for the application and then get the button in the window.
