DLL Injection, erro de codigo

[maximoreira]

Ando a testar um codigo em c++ de dll injection com a libraria detours.h, já instalei o detours 3.0 da microsoft e msm assim nao consigo correr o seguinte codigo:

#include <Windows.h> 
#include "detours.h"
#include <tchar.h> 
#include <stdio.h> 
// Function pointer to the original (un-detoured) DrawText API 
static int (WINAPI * TrueGetWindowTextA)(HWND hWnd, LPSTR lpString, int nMaxCount) = GetWindowTextA;
static int (WINAPI * TrueGetWindowTextW)(HWND hWnd, LPWSTR lpString, int nMaxCount) = GetWindowTextW;
 
 
void writeToFile(LPCWSTR text) 
{ 
    FILE *out; 
 
    if (!(out = fopen("C:\\out.txt", "a+"))) { 
        MessageBox (0,  TEXT("ERROR FILE"),  TEXT("ERROR FILE"), MB_ICONINFORMATION); 
        return; 
    } 
    fwprintf(out, text); 
    fclose(out); 
} 
 
int WINAPI MyGetWindowTextA(HWND hWnd, LPSTR lpString, int nMaxCount)
{
 int retVal = TrueGetWindowTextA(hWnd, lpString, nMaxCount);
 if (retVal != 0)
 {
  int charCount = strlen(lpString) + 1;
  LPWSTR pwszUniBuff = new wchar_t[charCount];
  if (0 != MultiByteToWideChar(CP_ACP, 0, lpString, -1, pwszUniBuff, charCount ) )
  {
   //writeToFile(lpString); 
  }
  delete [] pwszUniBuff;
 }
 return retVal;
}
int WINAPI MyGetWindowTextW(HWND hWnd, LPWSTR lpString, int nMaxCount)
{
 int retVal = TrueGetWindowTextW(hWnd, lpString, nMaxCount);
 if (retVal != 0)
 {
  //writeToFile(lpString);
 }
 return retVal;
}

bool InstallDetour(void** originalFunction, void* newFunction)
{
 LONG lError = DetourTransactionBegin();
 if (lError != NO_ERROR)
  return false;
    lError = DetourUpdateThread(GetCurrentThread());
 if (lError != NO_ERROR)
 {
  DetourTransactionAbort();
  return false;
 }
    lError = DetourAttach(originalFunction, newFunction);
 if (lError != NO_ERROR)
 {
  DetourTransactionAbort();
  return false;
 }
    lError = DetourTransactionCommit();
 if (lError != NO_ERROR)
 {
  DetourTransactionAbort();
  return false;
 }
 return true;
}

bool UninstallDetour(void* originalFunction, void* newFunction)
{
    DetourTransactionBegin();
    DetourUpdateThread(GetCurrentThread());
    DetourDetach(&originalFunction, newFunction);
    DetourTransactionCommit();
 return true;
}

 
bool Init()
{
 InstallDetour((void**)&TrueGetWindowTextA, MyGetWindowTextA);
 InstallDetour((void**)&TrueGetWindowTextW, MyGetWindowTextW);

 return true;
}

void Exit()
{
 UninstallDetour(TrueGetWindowTextA, MyGetWindowTextA);
 UninstallDetour(TrueGetWindowTextW, MyGetWindowTextW);
}

Tenho erro nas linhas

InstallDetour((void**)&TrueGetWindowTextA, MyGetWindowTextA);
 InstallDetour((void**)&TrueGetWindowTextW, MyGetWindowTextW);

122 C:\Users\win-7\Desktop\dllInjection\txt\main3.cpp invalid conversion from `int (*)(HWND__*, CHAR*, int)' to `void*'

Algum experts nesta area de dll injection que me seja capaz de explicar o q se passa aqui?

Não sendo nenhum expert em DLL Injection, nem grande utilizador de C++ vou tentar ajudar.
O Erro que estás a obter é porque a função que estás a passar para o detour retorna um valor inteiro.
Ele diz que não consegue fazer o cast de int para void.
