IRP Response

Hi,

I am trying to get a response while reading from the CD and writing
to the CD using IRP_MJ_READ and IRP_MJ_WRITE resp. But I don't get a
response. I have created a simple driver program for
FILE_DEVICE_CD_ROM. and added this driver as a lower filter driver to
the CDROM using devcon.exe. With this program I am trying to get a
message over the Debug View. But it is not going to that piece of
code. Please help me with this,because, I am new to the driver
development.


Thanks,
Aravind
