Window on Top?

[WadeD]

Hi, how can I tell if a window is in the foreground (on top) but not the active window? It wouldn't be covered by any other windows but it doesn't take up the entire screen so another window could be the active one. I just need to know if it can be seen.

Thanks for any help.

I've seen an API which returns the visible region of a window, I think Kedamans site had it (Class explorer screenshot)

Thanks guys. Paul, I didn't see the API at the site. Chris, the code you gave works great. Thanks again.
