<%@ Application Language="C#" %>
<%@ Import Namespace="System.Timers" %>

<script runat="server">

    void Application_Start(object sender, EventArgs e) 
    {
        // Code that runs on application startup
        System.Timers.Timer myTimer = new System.Timers.Timer();
        // Set the Interval to 10 seconds (10000 milliseconds).
        myTimer.Interval = 10000;
        myTimer.AutoReset = true;
        myTimer.Elapsed += new ElapsedEventHandler(myTimer_Elapsed);
        myTimer.Enabled = true; 
    }

    public void myTimer_Elapsed(object source, System.Timers.ElapsedEventArgs e)
    {
        clsScheduleMail objScheduleMail = new clsScheduleMail();
        objScheduleMail.SendScheduleMail();   
    }
    
    void Application_End(object sender, EventArgs e) 
    {
        //  Code that runs on application shutdown

    }
        
    void Application_Error(object sender, EventArgs e) 
    { 
        // Code that runs when an unhandled error occurs

    }

    void Session_Start(object sender, EventArgs e) 
    {
        // Code that runs when a new session is started

    }

    void Session_End(object sender, EventArgs e) 
    {
        // Code that runs when a session ends. 
        // Note: The Session_End event is raised only when the sessionstate mode
        // is set to InProc in the Web.config file. If session mode is set to StateServer 
        // or SQLServer, the event is not raised.

    }
       
</script>

  StreamReader reader = new StreamReader(Server.MapPath("~/HTMLPage1.htm"));
                    string readFile = reader.ReadToEnd();
                    string myString = "";
                    myString = readFile;



                    MailAddress fromMail = new MailAddress("ketanitaliya16@gmail.com");

                    Msg.CC.Add(new MailAddress(clientEmail(getClientId(lblclientname.Text))));


                    myString = myString.Replace("$$Client_Name$$", ev.Client_Name);
                    myString = myString.Replace("$$Event_Name$$", ev.Event_Name);

                    Msg.From = fromMail;


                    // Subject of e-mail
                    Msg.Subject = "Send Mail with HTML File";
                    Msg.Body = myString.ToString();
                    Msg.IsBodyHtml = true;

                    var smtp = new System.Net.Mail.SmtpClient();
                    {
                        smtp.Host = "localhost";

                        smtp.EnableSsl = false;
                        smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
                        smtp.Credentials = new NetworkCredential(fromMail.ToString(), "123456789");
                        smtp.Timeout = 20000;

                    }
                    smtp.Send(Msg);
                    reader.Dispose();
