Re: How to PostThreadMessages?

PostThreadMessage does not seem to work in my CWinThread inherited class.

Here is what I am doing:

1. Define my message:
#define MY_THREADMSG WM_USER + 1

2. Declare my message handler:
ON_THREAD_MESSAGE(MY_THREADMSG, OnMessage)

3. Create a thread:
g_pSerial = (ZSerialThread*)AfxBeginThread(RUNTIME_CLASS(ZSerialThread),
THREAD_PRIORITY_NORMAL, 0, CREATE_SUSPENDED, NULL);

4. Send messages to my thread:
g_pSerial->PostThreadMessage(MY_THREADMSG, (WPARAM)val1, (LPARAM)val2);

But my OnMessage function never gets called:

void ZSerialThread::OnMessage(WPARAM wParam, LPARAM lParam)
{
  switch (wParam) {
    case NEWCOM:
      if (lParam != NULL)
        ChangeCommPort((LPTSTR)lParam);
      else
        CloseSerialPort();
      break;
    case SCANIT:
      ScanSerialPort();
      break;
    case SETBOOT:
      SetBootModePin((BOOL)lParam);
      break;
    case STARTIT:
      StartSerialPort((LPTSTR)lParam);
      break;
    case TH_DON:
      PostQuitMessage(0);
      AfxEndThread(AfxGetThread()->m_nThreadID, TRUE);
      g_LoopSerial = FALSE;
      break;
  }
}

Could there be something wrong with the way I implimented the InitInstance
(below)?

BOOL ZSerialThread::InitInstance()
{
 // TODO: Add your specialized code here and/or call the base class
  configID = NULL;
  g_hPort = INVALID_HANDLE_VALUE;
  m_connecting = FALSE;
  m_bAutoDelete = TRUE;
  CWinThread::ResumeThread();
 return CWinThread::InitInstance();
}
//---------------------------------------------------------------------------

Yes, I am a little confused about this. I'll take any help I can get!
