Check if any other window is blocking my window/control

[philpw99 9]

Just had to program to make sure one of my control is visible and not blocked by any other window. Seems quite a useful feature for others.

This script comes with 2 functions: WinIsBlocked($hwnd) and WinControlIsBlocked($hwnd, $controlid). They will return true if another visible window is on top of them, covering even a tiny portion of them.

 

In the above example, when run WinIsBlocked( $hAutoItHelp ), it will return true, because the "AutoIt Window Info" is blocking it.

But when run WinControlIsBlocked( $hAutoItHelp, "Internet Explorer_Server1" ), it will return false, because the "AutoIt Window Info" is not blocking the right panel.

I know my code is pretty rough. Please let me know any suggestions and ways to improve it. Thank you !
