Overview

NextHooker is an open-source x86~~ text hooker for Windows.

Basically, GUI text hooker based on Stomp's ITHVNR.

See my Example Extension project to see how to build an extension.

To use an extension, simply rename the extension dll file to {NUMBER}_{NAME}_nexthooker_extension.dll and copy into the NextHooker folder.

Compiling

Before compiling NextHooker, you should get Visual Studio with CMake and ATL support, as well as Qt version 5.11
Use Visual Studio to compile all the CMake projects, then use Qt Creator to compile/run the GUI.

Project Architecture

The GUI links to vnrhost.dll (created from the texthook folder) which injects vnrhook.dll (created from the vnrhook folder) into the target process 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 file view (a.k.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.
