I'm making progress with a video driver for vnc (win 2000)
Status:
-driver can capture bitblt and blitcopy rectangle info direct from the
video card.
-At this point, the driver pass this info as Debug info to the windows
debugger
-winvnc read the debugger info and shows the rectangle info in his

Thanks for the hint, I forgot that the cached bitmaps are also copied
using drvcopybits.

buffer solved the problem of bad updates.

HI,
Finaly i'm getting some good result with the driver. (only W2K)
Winvnc don't need the message hooking anymore (except mouse).
-polling modes are no langer needed to get screen updates.
-scrolling and moving regions are well detected and most of the data can
be passed as copyrects
There is
probs:
some big screen-changes completely missed randomly(Start wordpad: no
update.
Close/reopen: perfect)
some small screen-changes are missed. The flashing cursor of a

it.
Typing into the command-line: only the bottom scanline
First of all, thanks for the input and bugs reports.

HI,
New testversion available to debug.
When you change the size of the application, the vnc client follows. No longer needed
to kill
the client for preventing desktop acces.
tested: win98 with winamp and wordpad.
