                richTextBoxReceive.Invoke(new MethodInvoker(()=>
                    richTextBoxReceive.AppendText(string.Format("{0}\n\r", msg))));
            }
            else
            {
                richTextBoxReceive.AppendText(string.Format("{0}\n\r", msg));
            }

            {
                richTextBoxReceive.AppendText(string.Format("{0}\n\r", msg));
        }
