A hook dll try to capture window message, to get hints about the
screen changes. ( Like draw button, set text...)


vnchook.dll
schook.dll

schook is used when both exist.

Both does the same, but use a different method.
schook.dll use the accesibility engine,
vnchook is pure hooking.
They behave different on different OS's... just try what's the best for you.

mirror video driver ( hook driver)

mv2 mirror driver: A driver capture at driver level the screen changes,
more accurate then hooking and a lot faster. But a mirror driver switch the real video driver in a non acceleration mode...
