I'd suggest posting in microsoft.public.win32.programmer.kernel (as a
starting point - there are also driver-specific newsgroups).

The results of DebugPrint can be viewed with a kernel debugger (e.g. kd,
windbg) or with a debug viewer like DbgView (from SysInternals, now
Microsoft Technet).

Hi Hugo,

this is simple. What you need is a tool like DbgView from Sysinternals.
You can get it from here:
http://technet.microsoft.com/en-us/sysinternals/bb896647.aspx

The Term "Filter Driver" does not say WHAT kind of Filter driver
you want to write(bus-filter,ll-device filter,ll-class filter, ul-filter,
Multimedia?)
because there are lots of Filters you can write, for any purpose. I
recommend
this source (below) for you, though this is a driver and kernel newsgroup. I
would like to write more here, but be sure that someone will tell me, that i
should not answer you!

Anyway, see here:

In future ask your questions regarding DDK and related here:

microsoft.public.development.device.drivers

Kerem
