MFC编辑框接收数据动态更新与刷新方法代码示例-如何让编辑框内容实时更新

关键代码：

//发送数据通知
//from txwtech@163.com
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;
