- Prison Code Breaker Diary -

This is the most simple version of DLL Injection

1. VC++ 2k5 (any version is ok), New Project -> Win32 Project
- Empty Project DLL

2. Add new C source file:

#include <windows.h>

BOOL APIENTRY DllMain( HINSTANCE hIns, DWORD reason, LPVOID reserved )
{
  switch( reason )
  {
      case DLL_PROCESS_ATTACH:
          MessageBoxA( NULL, "Process Attach", "MsgBox", 0 );
          break;
      case DLL_PROCESS_DETACH:
          MessageBoxA( NULL, "Process Detach", "MsgBox", 0 );
          break;
      case DLL_THREAD_ATTACH:
          MessageBoxA( NULL, "Thread Attack", "MsgBox", 0 );
          break;
      case DLL_THREAD_DETACH:
          MessageBoxA( NULL, "Thread Detach", "MsgBox", 0 );
          break;
  }

  return TRUE;
}

3. Build project in Release mode.

4. Use a DLL Injector to inject this DLL into any process.
- You can use this Injector: Winject (by mcMike)

[*] I will mention about writing injector later on.

Have fun!@
