Does anyone know of a program that enumerates all the running Window classes in a Tree View format? I'm pretty sure that I could make one but I would like to see one already available.
Filemon from sysinternals.com.
Doh, wrong product. What i meant to say was Microsoft Spy++, available as part of the PlatformSDK.
Thanks, sluggy. Spy++ is exactly what I was looking for and it was on my PC all the time.
