Write a WDM driver

Hi,

I wanted to write a Mouse filter driver which will intercept the mouse
click and trigger the user applications like those in the logitech ,
but not their own.. i wanted to invoke my own applicatoins.
I have tried to write the mouse driver but got stuck..
I am stuck at this point as what approach I should take? If I should
take the HID class help or what ... ?
I have fair understanding of the WDM but not done any fillter
drivers...
I want to the driver on the machines and configure the mouse to open my
application intercepting the mouse clicks..
I would really appreciate if anybody gives me the proper direction on
designing the driver..

thanks.

Just how long have you been looking at the mouse and keyboard filter driver
samples in the DDK? I'd recommend you use KMDF, which has samples also.

Thaks Gary for the quick response.
Actually all I wanted to do is alter the mouse functionality ...
Thats why I wanted to write a WDM Driver..
I am not that much aware of KMDF..
so things are getting little clumsy...
Please let me know the direction..

It is not necessary to dive into kernel mode for this. You can write a
windows hook to catch mouose clicks and do what you want.

Yeah, Thatss true.

But my objective here is to write a driver for it.
I have already started on it and has a skeleton ready for the driver
with basic IRP handling and IOCTLS.
I just need to catch the mouse events generated...
I am looking how can I pass those events designated as IOCTL to my
driver...
Is the driver sitting as a filter able to catch those events?
What IOCTLs it will generate... press this key , pressed that button?
Actully i just wanted to alter the default working by overriding with
my driver.
Is this possible?
Also If I have to write a driver , suppose a startup driver then which
device is recommended
to which I can apply the driver..
I have searched a lot and thought mouse will be better option...
Is there any other simple hardware I can control , then please advise
as well..

thanks.

I have always thought that there was no way to (cleanly) use a Windows
hook to actually *intercept* (i.e. prevent delivery of) mouse clicks and
do something else instead. I've often stated that such a need is the
only reason to write a mouse filter driver.

Do you know something I don't?

Highly doubtful. If you are speaking from hard experience, I defer to you
in this.
