You should choose Win32 Dynamic Linked Library instead of MFC AppWizard (DLL).

After choosing that, select "A simple DLL project". Overwrite the original DllMain function that VC++ provides with this DllMain function that you have at the end of your codes:

bool APIENTRY DllMain(HMODULE hModule, DWORD dwReason, LPVOID lpvReserved)
{
if(dwReason == DLL_PROCESS_ATTACH)
{
  DisableThreadLibraryCalls(hModule);
  Bypass();
  return true;
}
return true;
}
