Hi All:
DrvNotify gives u DN_DRAWING_BEGIN in the itype
member. Notifies the driver that the first drawing
operation is about to occur for this instance of the
PDEV that is associated with the specified surface.
Now in case of Mirror Driver when i attach it to
desktop i receive it only once ( understandable ) but
how can i get furthur notifications of drawing
operations on desktop… I think DrvPaint could have
been useful but 2000 doesnot call it now… It is
replaced by DrvFillPath and DrvStrokePath etc but they
both are not taking me anywhere.
All i need to know is how to get notified by the
GDI when any change in the desktop occurs.
Video Mirroring is active on Mirror drivers but i
cannot afford continuous blitting operation in this
case if all i need is to transport Desktop updates to
a location of my choice…
Hope i am clear enough.
I have posted before regarding Mirror Drivers but no
satisfied answer so far… Any useful resource in
anyones mind is appreciated… OR how to get support
from Microsoft say.

Check the iUniq parameter of the SURFOBJ. It is incremented only if
there is a change in the state of the surface.
-Ameet!
