Hi it's me again.
So about my topic, I need some enlightenment about driver things.
I am trying to create a keyboard simulator, which sends keystrokes at a D3D Environment. Most likely for games.

First, PostMessage doesn't work on sending left or right arrow.
Second, SendInputs are blocked by anti-hack softwares which gives me no other choice than to create drivers.
Upon researching, I found this inpout32.
Found the code and tried to compile it.
After that, I copied the dll and use LoadLibrary to work it under my workspace.

I am working on it and In32/out32 loads successfully.
Now when I am trying to use the method outport(0x64, btScanCode), it always gives me an access violation. Now I don't know if it is really working.
Can anyone help me with these things?
