            string content = comboBox1.Text + "\r\n" + textBox_server_port.Text;
            Http_Class.WriteConfigFile(content);
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            textBox_server_port.LostFocus += new EventHandler(save_ip_port);
            comboBox1.LostFocus += new EventHandler(save_ip_port);
