[Source] C# EndScene hook example

[barthen]

Credits:
Using bobbysing's dll injector. You can use whatever you like.
The C# code is 99.99% Apoc's WhiteMagic sample.


What it is:

Your typical D3D hook but in C# (for those starting with .NET bots). Attached you can find a Visual Studio 2008 solution with two projects:

- A C++ dll that launches the .NET Runtime and loads the C# module

- A C# module that hooks EndScene and calls a Pulse function every frame

Requires Apoc's WhiteMagic to work (dll included, four source please see Apoc's WhiteMagic thread)

Hope you find it useful

1) Don't create threads in DllMain (see DllMain Callback Function (Windows) Warning). Potential deadlock.
2) Your mixing of wchar_t and char astonishes me.
3) You use deprecated CLR hosting functions and will not be able to run .NET Framework 4.0 stuff.

The C# stuff is fine I guess

To add to what caytchen already brought up:
* You're potentially dereferencing an invalid pointer. Notice that you don't initialize 'pClrHost' except in the call to 'CorBindToRuntimeEx'. If that call fails then the statement 'pClrHost->Start()' will explode with an access violation. Bad mojo. Initialize pClrHost to 0 then do null-checking and error checking. Obviously that's not the only place where you're missing error handling, but it's the most dangerous one.
* As a solution to caytchen's first point (don't create threads in DllMain), just use an export and have your loader call it remotely.

P.S. The mixing of wide and narrow strings made me wtf too, lol.
