   {
      StreamWriter log;
      if (!File.Exists(temporary + "\\" + "Failed" + "\\" + "logfile.txt"))
      {
         log = new StreamWriter(temporary + "\\" + "Failed" + "\\" + "logfile.txt");
      }
      else
      {
         log = File.AppendText(temporary + "\\" + "Failed" + "\\" + "logfile.txt");
      }

      // Write to the file:
      log.WriteLine("Filename:" + filename);
      log.WriteLine("Data Time:" + DateTime.Now);

      log.WriteLine("Exception Message:" + sExceptionMessage);

      log.WriteLine("Exception:" + sexception);
