Hi,
What is the best way to detect if a specified printer driver is being
used by the system (Win 2K/XP/2K3)?
This info is required to prompt the user to close the ui/delete the jobs
etc before uninstalling the current version and updating it with a newer
driver.
Any info on this will be very helpful
Thanks
Shalini

mark,
Filesystem filter drivers might do this to, for example, open and scan
a
file for viruses before allowing a user open to succeed.
but then the upper level driver will eventually get control of the
IRP, won’t it?
