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 still work to do on the the winvnc server site.
 -James 'Wez' Weatherall notified me to look at the code from Xvnc and
RDP2VNC to reduce update
with copyrects. Winvnc send only the biggest copyrect ,.... need to be
changed
-hookdll should only check mouse events

driver+winvncserver can be downloaded for testing
(winvnc server is build with the source from tridia "more debugs build
in")
file: winvncdrv.zip
http://services.simac.be/vnc/single/source

changes after betadrv
-copyrects are send 1 by 1 and verified with the normal region scan.
-bitblits are copied to the backbuffer, not scanned
-scan and no scan regions are subtract, no double rects anymore
-added back mouse hooking


Please test and send bugs or suggestions back.

Groeten
Rudi
