SendMessageCallback

[Thomas Halsvik]

Anyone familiar with this API?
I think I've found the right parameters of the callback function:

Function MyCallBackFunc(ByVal hwnd As Long, ByVal umsg As Integer, dwData As Long, lresult As Long) As Long


I don't know if this is right, because if I try to access the parameters dwData or lresult I get a visit from Dr. Watson.
Can anyone help me out here?
I need to be able to send some INFO through the dwData parameter to the callback routine.

Found it:

Function MyCBFunc(ByVal hwnd As Long, ByVal umsg As Long, ByVal dwData As Long, ByVal lresult As Long) As Long


Hope this helps for Antonio Begue.
