>2 and all other GW_... are Windows constants, i.e. you will use 2 to get 'next' window (as described for GW_HWNDNEXT) using VB,VC etc. It's another story that MS used to hide this values (for all WinApi function) in some differnet hard_to_find places. Here, on UT, you can always ask Mr. Tasker, he knows all of them.

Hi Ed,

I beg to differ. I don't know them all, but I know how to find most.:-) Seriously, they're all in the various header files that are provided with VC++ and the Win32 SDK. I do appreciate the compliment, though.
