关键代码：

//发送数据通知

LRESULT CCommSampleDlg::OnSendMsg(WPARAM dwEvent,LPARAM dwLen)
{
	if(!dwLen)	return 0;
	BYTE* temp = new BYTE[dwLen+1];
	memset(temp, 0x00, dwLen+1);
	memcpy(temp, (const void*)dwEvent, dwLen);
	CString log;
	log.Format("\r\n发送数据=%s", (LPCTSTR)temp);
	
	if (m_editLog)
	{	
		CEdit* editLog=(CEdit*)FromHandle(m_editLog);
		if (editLog->GetWindowTextLength()>50000)		
		{
			editLog->SetSel(0,-1);
			editLog->Clear();
			editLog->SetSel(0,0);
			editLog->ReplaceSel(log);
		}
		else
		{
			editLog->SetSel(editLog->GetWindowTextLength(),editLog->GetWindowTextLength());
			editLog->ReplaceSel(log );
		}
	}	
	return 0;
}

// 接收消息通知
LRESULT CCommSampleDlg::OnRecvMsg(WPARAM dwEvent,LPARAM dwLen)
{
	if(!dwLen)	return 0;
	BYTE* temp = new BYTE[dwLen+1];
	memset(temp, 0x00, dwLen+1);
	memcpy(temp, (const void*)dwEvent, dwLen);
	CString log;
	log.Format("\r\n接收数据=%s", (LPCTSTR)temp);

	if (m_editRecv.GetLength() > 50000)	m_editRecv = "";
	m_editRecv += log;	
	UpdateData(FALSE);
	return 0;
}
