Hi KM,

I am making a "video streamer" and I'd like this device boot as quickly as
possible and always with the same configuration. So HORM is perfect for me !
But when I boot I'd like my "video streamer" streams automatically. The
problem is that my video capture card prevent hibernation so to hibernate I
must first stop the capture process but when my device restarts, my
application cannot stream :(
( There are same kind of problems with network applications with openned TCP
sockets)

So it would be great if windows could notify to the running applications
that he has been restarted.

Is there a way to do this ?

what do you want to say with the word "temporarily" ?

NB. I can do exactly what I want without hibernation but hibernation is very
nice for quick boot :)

thanks
Mike
