How to create a job scheduler in application?

Before 6 months I was working on one web portal, there was requirement to auto send mail to trial register users and that site was hosted on shared server and we are using sql server 2005 express edition. So there was only one option to create a scheduler in application.

At first time I faced so much problems, at finally I did like this

Note: Here I have tested the concept with database.

Srep1: Create a “Global.asax”.

Step2: Create one Class i.e DoSomeWork and write the code for insert in database like this and create a table in database with field Id,msg, and sentDate to check this concept

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data;
using System.Data.SqlClient;

/// <summary>
/// Summary description for DoSomeWork
/// </summary>
public class DoSomeWork

public void DoSomeWorkWithDB()

//code for storing in database
// You can also write code for sending mail to some one on some condition

using (SqlConnection con = new SqlConnection("Data Source=.\\sqlexpress;Initial Catalog=Test;Integrated Security=True"))
using (SqlCommand cmd = new SqlCommand("Insert into tblMsg(msg) values(@msg)", con))
cmd.Parameters.AddWithValue("@msg", "This is the test message");



Step3: In “Application_Start “ method of Global.asax file, use the timer concept and assign the time interval to run that block of code like this.

<%@ 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)

DoSomeWork obj1 = new DoSomeWork();

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)



Step3: Now run the application. It will insert data in database in every 10 second.

Note: You have some better idea to do this task then feel free to share with me. You are always welcome.

    Wouldn’t this be quite waist-full running a timer all the time?

    • Chandra Dev Says:

      Yes. This one is not acceptable in big project.There generally we used to create window job scheduler.
      I have written one approach for doing that task.

  3. vijay Says:

    If you use this type of will not affect that server response..bcz its keep on running on every 10 seconds…..For better choice go for window

    • Chandra Dev Says:

      Thank you for sending your suggestion. I agree with you.But if somebody is working for small client and client has not their own server then we cannot use window job scheduler.

      In my sample, I m running the timer every 10 sec.we can also set the timer to run only one time in whole day by increasing time interval.
