Part 1: How to develop custom timer job in sharepoint 2010 using visual 2010

Step 1: Open Visual Studio 2010 | New Project | Empty Sharepoint Project | its name TimerJob2010

Step 2: Choose “Deploy as farm solution”

Step 3: Add new Class, its name TimerJobClass.cs

Step 4: Inherit class from Microsoft.SharePoint.Administration.SPJobDefinition class. And code as

Code here

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using Microsoft.SharePoint.Administration;

using Microsoft.SharePoint;

namespace TimerJob2010

{

    class TimerJobClass : SPJobDefinition

    {

        public TimerJobClass()

            : base()

        {

        }

        public TimerJobClass(string jobName, SPService service, SPServer server, SPJobLockType targetType)

            : base(jobName, service, server, targetType)

        {

        }

        public TimerJobClass(string jobName, SPWebApplication webApplication)

            : base(jobName, webApplication, null, SPJobLockType.ContentDatabase)

        {

            this.Title = "Timer Job 2010";

        }

        public override void Execute(Guid contentDbId)

        {

            // get a reference to the current site collection's content database

            SPWebApplication webApplication = this.Parent as SPWebApplication;

            SPContentDatabase contentDb = webApplication.ContentDatabases[contentDbId];

            // get a reference to the "ListTimerJob" list in the RootWeb of the first site collection in the content database

            SPList Listjob = contentDb.Sites[0].RootWeb.Lists["TimerJob2010"];

            // create a new list Item, set the Title to the current day/time, and update the item

            SPListItem newList = Listjob.Items.Add();

            newList["Title"] = DateTime.Now.ToString();

            newList.Update();

        }

    }

}

Step 5: Right click on Feartures | Add Feature

Step 6: You can rename Feature as

Step 7: Right click on Feartures | Add Event Receiver

Step 8: Code as

Code here

using System;

using System.Runtime.InteropServices;

using System.Security.Permissions;

using Microsoft.SharePoint;

using Microsoft.SharePoint.Security;

using Microsoft.SharePoint.Administration;

namespace TimerJob2010.Features.TimerJobFeature

{

    /// <summary>

    /// This class handles events raised during feature activation, deactivation, installation, uninstallation, and upgrade.

    /// </summary>

    /// <remarks>

    /// The GUID attached to this class may be used during packaging and should not be modified.

    /// </remarks>

    [Guid("3bec3dd0-3cf3-419e-8c12-1adcbf7d2abc")]

    public class TimerJobFeatureEventReceiver : SPFeatureReceiver

    {

        const string ListTimerJob = "ListTimerJob";

        // Uncomment the method below to handle the event raised after a feature has been activated.

        public override void FeatureActivated(SPFeatureReceiverProperties properties)

        {

            SPSite site = properties.Feature.Parent as SPSite;

            // make sure the job isn't already registered

            foreach (SPJobDefinition job in site.WebApplication.JobDefinitions)

            {

                if (job.Name == ListTimerJob)

                    job.Delete();

            }

            // install the job

            TimerJobClass listLoggerJob = new TimerJobClass(ListTimerJob, site.WebApplication);

            SPMinuteSchedule schedule = new SPMinuteSchedule();

            schedule.BeginSecond = 0;

            schedule.EndSecond = 59;

            schedule.Interval = 5;

            listLoggerJob.Schedule = schedule;

            listLoggerJob.Update();

        }

        // Uncomment the method below to handle the event raised before a feature is deactivated.

        public override void FeatureDeactivating(SPFeatureReceiverProperties properties)

        {

            SPSite site = properties.Feature.Parent as SPSite;

            // delete the job

            foreach (SPJobDefinition job in site.WebApplication.JobDefinitions)

            {

                if (job.Name == ListTimerJob)

                    job.Delete();

            }

        }

    }

}

Step 9: Right click Feature | View Designer

Step 10: Change cope from Web to Site

Step 11: If cope incorrect, appear as

Step 12: Build project and Deploy it

Step 13: Go to Central Admin | Check job status

Step 14: You see custom timer job created, click to timer job and configure

Step 15: Configure time execute

Step 16: Open your web application | Open your  list and see item was created
