                if (this.progressBar1.Value >= 100)
                {
                    this.progressBar1.Value = 0;
                }
                this.progressBar1.Value++;
                this.labeltitle.Text = "通讯中";            }            else
            {
                this.progressBar1.Value = 0;
                this.labeltitle.Text = "状态";
                timer1.Stop();
                //if(this
                if (dataGridView1.RowCount == 1)
                {
