Well, I have been assigned the jolly task of writing a device driver for a
piece of hardware that we have.  The fun and interesting part of all this is
that I had planned to simply poll this hardware every 8ms and handle the data
in a big loop.  This way I could write the routines as part of a DLL and that
would be that.

Now if you are quick, you'll notice the problem.  A timer event has a maximum
resolution of 54ms.  There is no way to poll the card quickly enough.  That
means that I must enable the hardware interrupt that the card generates and
trap that.  THIS IS THE PROBLEM!

How does one trap a hardware interrupt in Windows?  I really am in a bind until
I can do this, so any help is appreciated.  If sample source code is available
that would be great...

thanks in advance...
jeff
