EQEmulator Forums - Client Hooking with CDetours: Console Logging

Wrote this small bunch of code using the CDetours library. It hooks the EQ Client and outputs the dbg.txt stuff in a console instead of a file. Included here is the dbg.txt logging address for SoD clients, the CDetours library, and the source that logs to a console.

Instructions:

1) DLL is an empty win32 DLL project. Copy + Paste the the source into an empty cpp file.

2) Add CDetours to the windows path like you would with the includes for MySQL/Perl/Zlib.

2a) Compile the DLL

3) Use a DLL injector like InjeX or Injec-TOR to inject the DLL into eqgame.exe

4) Enjoy your console in eqgame.

Code:

#include <windows.h>

#include <stdio.h>

#include <string>

#include <CDetour.h>

#pragma comment( lib, "detours.lib" )



DWORD LogAddr = 0x006B0BB0;



CDetour LogDet;





void LogHook(const char* two, ...)

{ 



char val[256] = "{0}"; 

HANDLE stdoutthing = GetStdHandle(STD_OUTPUT_HANDLE);

const char* sep = "\n";

unsigned long stufftowrite = 0;

va_list va;

va_start(va, two);

_vsnprintf_s(val, 255, two, va); 

WriteConsoleA(stdoutthing,val, strlen(val), &stufftowrite, 0);

va_end(va);

stufftowrite = 0;

WriteConsoleA(stdoutthing,sep, strlen(sep), &stufftowrite, 0);

LogDet.Ret(false);

}



int WINAPI DllMain(HINSTANCE hModule, DWORD dwReason, LPVOID)

{

        if(dwReason == DLL_PROCESS_ATTACH)

        {

                LogDet.Detour((PBYTE)LogAddr, ( PBYTE )LogHook);



                if(!AllocConsole())

                {

                        return 0;

                }

                SetConsoleTitle(TEXT("EQ Console"));

                LogDet.Apply();

        }

        else if(dwReason == DLL_PROCESS_DETACH)

        {

                LogDet.Remove();

        }

        return 1;

}
