 #define THRD_MESSAGE WM_USER + 2

DWORD WINAPI test::ThreadWorkItem(LPVOID lpParameter)
{
 MSG msg;
 while (true)
 {
  BOOL MsgReturn = ::PeekMessage(&msg, NULL, 0, 0,PM_REMOVE);//程序会立刻返回

 //BOOL MsgReturn = ::GetMessage(&msg, NULL, 0, 0);//程序阻塞接受消息

  if (MsgReturn)
  {
   switch ( msg.message )
   {
   case THRD_MESSAGE:
    {
     break;
    }
   default:
    cout<<"Error!"<<endl;
    break;
   }
  }
 }
 return 0;
}

int _tmain(int argc, _TCHAR* argv[])
{
 test oTest;
 oTest.Start();

 PostThreadMessage (oTest.m_dwThreadID, THRD_MESSAGE, 0,0);

 Sleep(100);
