WH_JOURNALRECORD hook

I'm writing a control to allow remote monitoring and shadowing of VB apps that uses a WH_JOURNALRECORD hook. All works grand, returning an EVENTMSG structure whenever the user interacts with my app - but I need to convert this to a proprietry message format 'cos the .hwnd on the remote machine is fairly meaningless on the debugging machine...so, I have the following structure:


Type EVENTMSG
message as Long
paramL as Long
paramH as Long
time as Long
hwnd as Long
End Type




From investigation, message is a WM_* message and paramL and paramH vary according to what message it is
(i.e. for all the mouse messages, paramL is the x position and paramH is the y position)
but hwnd is often zero so I have to do an IsWindow around that.

Anyhow - (1) Anyone have any documentation on EVENTMSG that specifies the link between the message and the meaning of the paramH and paramL members or will I have to do all that all by trial and error, and (2) anybody got a better way of getting the control name and index from the .hwnd without iterating the controls collections?

Thanks in advance,
Duncan
