Hello everyone,

I have a static address I'd like to code into a trainer, but the address is not something like 12345678, it's more like "game.exe"+0002347C.

My code looks something like this:

Code:

// console trainer, read / write in C++

DWORD pointer = baseAddress;
DWORD pTemp;
DWORD pointerAddr;

for( int c = 0; c < pointerLevel; c++ )
{
   if( c == 0 )
   {
      if( !ReadProcessMemory( hProcHandle, (LPCVOID)pointer, &pTemp, 4, NULL ) )
         cout << "FAILED READ 1" << endl;
   }
   pointerAddr = pTemp + offsets[c];
   if( !ReadProcessMemory( hProcHandle, (LPCVOID)pointerAddr, &pTemp, 4, NULL ) )
      cout << "FAILED READ 2" << endl;
}

if ( !WriteProcessMemory(hProcHandle, (BYTE*)pointerAddr, &value, sizeof(value), NULL) )
   cout << "FAILED WRITE" << endl;
else
   cout << "WORKS" << endl;


How do I get "game.exe"+0002347C to go into the ReadProcessMemory and WriteProcessMemory functions?

Thank you.

Max

Hi Innovation,

Thanks for the link.

I'm having some difficulty with initializing TCHAR using the memory module. When I do:

Code:

baseAddress  = dwGetModuleBaseAddress( processId, "\"game.exe\"+00012345" );


dwGetModuleBaseAddress always returns 0. I set processId like this:

Code:

// Set processId

DWORD processId = NULL;
PROCESSENTRY32 pe32 = {sizeof(PROCESSENTRY32)};
HANDLE hProcSnap;
HANDLE hProcHandle;

while(!processId)
{
   system("CLS");
   cout << "Searching for " << processName <<"..." <<endl;
   hProcSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
   
   if(Process32First(hProcSnap, &pe32))
   {
      do
      {
         if(!strcmp(pe32.szExeFile, processName))
         {
            processId = pe32.th32ProcessID;
            break;
         }
      }
      while(Process32Next(hProcSnap, &pe32));
   }
   Sleep(1000);
}


Which appears to be a valid processId. I'm assuming it's the way I am entering the TCHAR value. What could be wrong?

Thank you.

Max

---------- EDIT -----------

I found a previous post by Innovation that utilizes this function. I tried setting the TCHAR like this:

Code:

DWORD speedMovBaseAddress  = dwGetModuleBaseAddress( processId, _T("game.exe+00012345") );


It still returned 0. Then I tried:

Code:

DWORD speedMovBaseAddress  = dwGetModuleBaseAddress( processId, _T("game.exe") );


And it returned "FAILED READ 2" from the bit of code I included in my first post to this thread. I believe it is because I was not able to account for the +00012345 part of the memory module. Any ideas?

Thanks

Max

---------- EDIT -----------

My updated code looks something like this:

Code:

// console trainer, read / write in C++

DWORD baseAddress = dwGetModuleBaseAddress( processId, _T("game.exe") );
DWORD staticOffset = { 0x12345 };
DWORD offsets = { 0x12, 0x34, 0x56 };

DWORD pointer = baseAddress;
DWORD pTemp;
DWORD pointerAddr;

for( int c = 0; c < 3; c++ )
{
   if( c == 0 )
   {
      if( !ReadProcessMemory( hProcHandle, (LPCVOID)(pointer+staticOffset), &pTemp, sizeof(DWORD), NULL ) )
         cout << "FAILED READ 1" << endl;
   }
   pointerAddr = pTemp + offsets[c];
   if( !ReadProcessMemory( hProcHandle, (LPCVOID)pointerAddr, &pTemp, sizeof(DWORD), NULL ) )
      cout << "FAILED READ 2" << endl;
}

if ( !WriteProcessMemory(hProcHandle, (BYTE*)pointerAddr, &value, sizeof(value), NULL) )
   cout << "FAILED WRITE" << endl;
else
   cout << "WORKS" << endl;


I keep getting "FAILED READ 2". It's difficult to debug this given that I don't know if I'm doing the "game.exe"+00012345 part right. Maybe someone else sees something I don't?

Thanks

Max

---------- EDIT (Still can't reply twice in a row) -----------

It was an offset issue, my offsets were listed backwards. All good now.
