private void button1_Click(object sender, EventArgs e)
        {
            EventLog EventLog1 = new EventLog("Security", "OIRC-09");
       </code>   
          
            foreach (System.Diagnostics.EventLogEntry entry in EventLog1.Entries)
            {
                if (entry.Category == "Logon/Logoff")
               ListBox2.Items.Add(entry.Message+"\n");
            }
