## Project Architecture
2018-05-26 18:38:24 +08:00
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.< br >
2018-05-21 09:21:37 +08:00
vnrhost writes to hostPipe, vnrhook writes to hookPipe (duh?)< br >
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.< br >
2018-06-01 21:56:40 +08:00
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.< br >
2018-05-21 09:21:37 +08:00
The text that vnrhost receives through the pipe is then processed a little before being dispatched back to the GUI and displayed.
