I have written a mirror driver for Win2000. It stores the screen data and
rectangles of the updated sections in a shared memory. I retrieve this info
from my application(at the user mode) and it seems to be working fine.

But now I want to write a similar driver for WinNT. I handled additional Drv
functions such as DrvStretchBlt, DrvStrokeAndFillPath etc and built the code
in the WinNT environment. But it does not work.

Can anyone tell me what changes need to be done to enable the Win2k mirror
driver to run on WinNT ? Is there any differnce in initialization done in
DrvEnablePdev()?

Thanks in advance,
S.J

The creation of surface in Windows NT and 2k (and later)
is different. Its documented in DDK. Hope this could help
you.
