Think ppl dont reply because your post isn't to clear.

I think you wanted to know the following constants:
Code:
Public Const WM_USER = &H400
Public Const WM_COMMAND = &H111
Public Const WM_COPYDATA = &H4A

But then again im not sure if that is what you meant.


BTW I got these constants from the API Viewer(comes with all flavors of VB i think).
