C# code that automatically gets Endscene (DirectX9) and Present (DirectX 11) offsets

[highvoltz]

The attached source code demonstrates how you can automatically get pointer to EndScene for DirectX9 or Present for DirectX11 depending on which directX version is being used in target Process (automatically detected).

Sample usage.

Dirext3D dx3D = new Dirext3D(wowProc); // wowProc is a System.Diagnostics.Process
InstallHook( dx3D.HookPtr);    // Yes, its this simple. HookPtr points to either Endscene or Present depending on which directX is being used in target process and InstallHook is my function that installs the hook.

Credits:
Apoc: Based off Apoc's source for getting Endscene offset using same technique. I improved on it and added support for directX 11 and automatic directX version detection and more. Also uses his Grey Magic library.

Super, thx, works great!!! +rep

Thanks for the upload. I've been too lazy to update my work for DX11. Now maybe this convinces me to do it lol

Function entry point on Windows 8:

.text:1001F8DF 6A 14                          push    14h
.text:1001F8E1 B8 0C 9A 14 10                 mov     eax, offset loc_10149A0C

you can make your hook work on any version of Windows or DirectX if you use a short jump (2 bytes) to jump up to the function padding and replace the function padding with your long jump.

Unfortunately I'm getting errors like this:

i searched the web, but couldn't find a solution. Anyone an idea?

This was used as an honorbuddy plugin i think, You need to add the Dll imports that it uses.

public static class NativeMethods
    {
        [DllImport("kernel32.dll", CharSet = CharSet.Auto)]
        public static extern IntPtr GetModuleHandle(string lpModuleName);

        [DllImport("kernel32", SetLastError = true, CharSet = CharSet.Unicode)]
        public static extern IntPtr LoadLibrary(string lpFileName);

        [DllImport("kernel32.dll", SetLastError = true)]
        [return: MarshalAs(UnmanagedType.Bool)]
        public static extern bool FreeLibrary(IntPtr hModule);
    }

Ahh okay, did not know that.
Now it compiles.
But it hangs somewhere forever and nothing happens.
Thanks anyway!
