newbie: install moufiltr example

NTDEV
1

Hey everyone,

A real newbie question here… I’d like to use the moufiltr example as a “hello world” starting point for playing/learning about windows drivers development. I’ve downloaded the DDK, and built the moufiltr example. I’d now like to install it so I can start mucking with the code to understand what’s going on. Is there a simple few steps I can follow to easily get this out-of-the-box build up and running? Thanks for the help.

Is your end game that you want to know how to write a driver in general or do you have a specific driver you want to write? Moufiltr is actually quite empty. Outside of the boilerplate pnp/power code, there is very little there to learn. There could be better samples out there depending on the results you want.

I would recommend that you download KMDF, http://www.microsoft.com/whdc/driver/wdf/KMDF_pkg.mspx, so that you don’t have to learn all the boilerplate pnp/power code and just focus in on the rest of the driver mdoel.

There are a ton of whitepapers on WHDC, starting at http://www.microsoft.com/whdc/driver/default.mspx, have you looked through them to see if any of them help?

Thanks for the suggestions so far. My requirements are actually pretty basic (I hope). For now, I just need to write a lower filter for the Windows PS/2 mouse driver so I can intercept/modify mouse actions. I was hoping to get the stock moufiltr installed, then just add the functionality I need.

I’ve tried using OSRLOADERwith the built moufiltr.sys. It successfully registered the service, but when I try to start it, I get an Eror of “service cannot be started, either because it is disabled or because it has no enabled devices associated with it.”

Thanks again,
~Dave

You need upper filter and not lower. i8042prt does direct hardware accesses,
so, its lower filter will only see PnP and Power IRPs.
