How can I make one with C++? I thought this stuff was all ASM...

Throw these into MSDN. Behold:

FindWindow
GetWindowThreadProcessId
OpenProcess

Write/ReadProcessMemory

I suggest not using FindWindow to get the handle / procid of the process as it's outdated now adays as some games have the window name and/or the class name change constantly to avoid people from using that API to detect the window.

Instead you can use CreateToolhelp32Snapshot to get what you need.

An example in C++:

Code:

DWORD GetProcessId(char * szProcName)
{
   PROCESSENTRY32 pe32 = {0};
   HANDLE hSnapshot = 0;
   DWORD dwProcId = 0;

   if( Process32First( hSnapshot, &pe32 ) )
   {
      do{
         if( strcmp( szProcName, strlwr(pe32.szExeFile) ) == 0 )
         {
            dwProcId = pe32.th32ProcessID;
            break;
         }
      } while( Process32Next( hSnapshot, &pe32 ) );
   }

   if( hSnapshot != INVALID_HANDLE_VALUE )
      CloseHandle( hSnapshot );

   return dwProcId;
}
