Note. This wont be any sense/fun for beginners.

I'd go with RegisterShellHook DLL Call

That way, your script gets notified ASAP when a window opens or closes. Heres an example script about how to register a "Shell Hook" as well as what the messages your script will receive.

@Conquer

I would like to detect when a window closes. I have an app that needs to refresh a window whenever a child window closes. I would like to send the refresh automatically.

SHELLHOOK will not work for Child Windows and BTW the relevant post is here : How to Hook on to Shell to receive its messages ?
