private void btnReadMessages_Click(object sender, System.EventArgs e)
{
  Cursor.Current = Cursors.WaitCursor;
  string storage = GetMessageStorage();

  try
  {
    // Read all SMS messages from the storage
    DecodedShortMessage[] messages = comm.ReadMessages(PhoneMessageStatus.All, storage);
    foreach(DecodedShortMessage message in messages)
    {
      Output(string.Format("Message status = {0}, Location = {1}/{2}",
                    StatusToString(message.Status), message.Storage, message.Index));
      ShowMessage(message.Data);
      Output("");
    }
    Output(string.Format("{0,9} messages read.", messages.Length.ToString()));
            Output("");
