Is it possible to call a function in a usermode dll
from a device driver? If possible using explicit linking.

It might be ‘possible’ but it would be the wrong thing to do.

Well, I know it is not the standard but…if I were to
do it how would I go about that?

Fair enough.

Is it possible to start an executible such as an
installshield from a device driver?

Thanks,

Never mind.
ZwCreateFile should suffice.
Thank you,

On Windows 98 APC can be used to call a ring 3 function from vxd. And on
Windows NT you can use Inverted Call mechanism ,but it’s toooo complex to
achive the inverted call ,as I know.
