建立基于CFormView的单文档程序,向COM口以敲入字符的方式发命令,接收到后,如何显示在View中呢?显示时,如何实现换行呢?
BOOL CMy1View::PreTranslateMessage(MSG* pMsg) 
{
    // TODO: Add your specialized code here and/or call the base class
    if(pMsg->message == WM_KEYDOWN) 
    {  i++;
       char *command;
       text+=pMsg->wParam;
              command=text.GetBuffer(10);
       if (!m_com.ComWrite(comnum,command,1)) 
       {
        ::MessageBox(NULL,"Can not write to com!",
            "Error",MB_OK|MB_ICONERROR);
        return FALSE;
       }
             char data[100];  
      if (!m_com.ComRead(comnum,data,1)) 
      {
        ::MessageBox(NULL,"Can not read from com!",
            "Error",MB_OK|MB_ICONERROR);
        return FALSE;
      }
     pMsg->wParam= ?        (如何把读出的字符转变给pMsg->wParam)
      }
    return CFormView::PreTranslateMessage(pMsg);
