How important is vnchooks.dll?

Guest · Post by **Guest** » 2005-10-09 16:19

What if I don't give the client vnchooks.dll ? I seem to control their computer just fine without it. So what do I miss? And is there a way to make WinVNC not even try to call it (in regular screen mode)?

If vnchooks.dll does not exist, it is not used.

What does it:
The hookdll inform vnc about screen changes...
rectangle changed at (x,y,w,h)

Without hookdll, the only method to find changes is to poll the full screen.
(cpu up)
Using the hookdll, you don't have to set full screen polling, keeping a lower cpu.

So without VNCHooks.dll, no matter which option is actually checked - "full screen polling" is used?

OS: 2000, XP, 2003
if you use mirror video driver, winvnc video hook driver
you don't need vnchooks.dll except below:

OS: NT4 95B/98/98SE/ME only support System HookDLL (DDI Hooking)
vnchooks.dll on theses system, the only way for fast screen update on old OS
