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 ;
     BYTE* temp = new BYTE[dwLen+];
     memset(temp, 0x00, dwLen+);
     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()>)

             editLog->SetSel(,-);
             editLog->Clear();
             editLog->SetSel(,);

         }
         else

             editLog->ReplaceSel(log );
         }
     }
     return ;
 }

 // 接收消息通知
 LRESULT CCommSampleDlg::OnRecvMsg(WPARAM dwEvent,LPARAM dwLen)

     if(!dwLen)    return ;
     BYTE* temp = new BYTE[dwLen+];
     memset(temp, 0x00, dwLen+);
     memcpy(temp, (const void*)dwEvent, dwLen);
     CString log;
     log.Format("\r\n接收数据=%s", (LPCTSTR)temp);

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