    <p>I am using Serial port to send sms through a GSM/Modem .My code is working with single sms. The problem arise when I try to send sms in bulk. Then no sms are sent and no exceptions are generated.</p> <pre><code> using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO.Ports; using System.ComponentModel; using System.Windows.Forms; namespace program.cs { public class Class1 { public string[] strarray = new string[10]; SerialPort serialport1 = new SerialPort(); string com = "COM8"; int mybaudrate = 9600; //this.strarray =System.IO.Ports.SerialPort.GetPortNames(); public void getports() { this.strarray = System.IO.Ports.SerialPort.GetPortNames(); } public bool connetport() { bool Isopen; serialport1.Close(); try { if (!this.serialport1.IsOpen) { this.serialport1.PortName = com; this.serialport1.Open(); this.serialport1.BaudRate = mybaudrate; this.serialport1.StopBits = System.IO.Ports.StopBits.One; this.serialport1.Parity = System.IO.Ports.Parity.None; this.serialport1.Handshake = System.IO.Ports.Handshake.None; Isopen= serialport1.IsOpen; } Isopen = true; } catch (Exception ex) { Isopen = false; throw ex; } return Isopen; } public void sendsms() { try { if (this.serialport1.IsOpen) { // to send bulk sms serialport1.BaseStream.Flush(); int loop = 0; int howmany = 0; howmany = 200; while (loop &lt; howmany) { System.Threading.Thread.Sleep(3500); string cb = char.ConvertFromUtf32(26); this.serialport1.Write("AT+CMGF=1\r"); this.serialport1.Write("AT+CSCA=servicecenter\r \n");//Ufone Service Center this.serialport1.Write("AT+CMGS=\"" + "03468916446" + "\"\r\n");// this.serialport1.Write("hello" + cb);//message text message sending System.Threading.Thread.Sleep(3500); loop++; } MessageBox.Show("Message Sent Number" + loop); serialport1.Close(); } } catch (Exception ex) { serialport1.Close(); throw ex; } } } </code></pre> <p>}</p> <p>Class1 above is used to connect and send sms</p> <p><br> Code For Main Program<br></p> <pre><code>public partial class Form1 : Form { public Form1() { InitializeComponent(); } bool check; Class1 obj = new Class1(); private void button1_Click(object sender, EventArgs e) { check = obj.connetport(); MessageBox.Show("Connecton Status" + check); obj.sendsms(); MessageBox.Show("have completed"); } } </code></pre> <p>I have invested a lot of time on solving this problem but without success.

    1. COUnderstand what Thread.Sleep does before you use it. That loop will take 23.3 minutes to complete the way you have it now. Also what errors are you getting. Also don't call serialport1.Close() in the beginning of connectport. Also work on your naming and formatting, like camelCase.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
