Catching driver messages

Hello,

I want to see if the driver of my capture card sends messages when it
recieves video input.

In order to do this, I built a Windows Service, which contains a message
loop.

How can I see if the message comes from the driver ?

The MSG structure provides me with a HWND, and the OpenDriver windows
function provides me with a HDRVR, but I don't know how to relate those two.

Thanks for any ideas.

Michiel.

This doesn't seem like a good idea to me. As a rule services should not run
on the interactive desktop. That means that they can exchange messages only
with other applications on the same invisible desktop.

I think you will want to post again in a group dedicated to video/video
driver issues.

Regards,
Will
