Compiling

Before compiling NextHooker, You should get CMake, Windows Driver Kit 7.1, and Visual Studio.

Project Architecture

The GUI links to vnrhost.dll (created from the texthook folder) which injects vnrhook.dll (created from the vnrhook folder) and connects to it via 2 pipe files.
vnrhost writes to hostPipe, vnrhook writes to hookPipe (duh?)
vnrhook waits for the pipe to be connected, then injects a few instructions into any text outputting functions (e.g. TextOut, GetGlyphOutline) that cause their input to be sent through the pipe.
Additional information about hooks is shared through a section object that is mapped to a reference to the Hook class.
The text that vnrhost receives through the pipe is then processed a little before being dispatched back to the GUI and displayed.
