Eric,

I don’t believe you can directly call a routine to display a message box
from kernel-land. You can make a thread that sends down an IRP using
the inverted call model and send it back up when you want to display a
message. The thread would note the return of the IRP and display a
message accordingly. If you need to pass text up from the driver, you
could (after receiving the IRP), call a special IOCTL that would let the
driver pass the message text back up to the user-land thread.

If you don’t want to use the inverted call model, you could have your
thread poll the driver at set intervals for a request to display a
message box.

If someone has a better solution to this issue, I’d be interested in
learning. But this method should work fine.

Sincerely,

Isn’t this call specifically for error messages? Or can it be used in
the general sense?
