RE: [GD-Windows] Hijacking application

[Gareth L. <GL...@cl...>]

Injecting a DLL into the address space of a process is basically running a
DLL as if it was loaded by the program itself. When you run a program in
MSVC you'll see all the DLLs loaded with your process, sometimes you'll be
surprised at what runs there (THere are a few programs that hook every
process as it runs)

SetWindowsHooksEx is the best way to do it.

Here is a nice tutorial about the stuff
