Today, in this article let's play around with one of the interesting and most useful concepts in SharePoint 2010.

Question: What is Full crawl schedule?

In simple terms "This type of crawl performs crawling for any specific content in the content source at some specified time".

Step 1: Open SharePoint 2010 Central Administration and navigate to a specific site.

Step 2: Open up Visual Studio 2012 and try to "SharePoint Visual Web Part" project, as in:

Step 3: Select "Deploy as a farm solution" as in the following and click the "Finish" button.

Step 4: The complete code of visualwebpart1usercontrol.ascx looks like this:

<%@ Assembly Name="$SharePoint.Project.AssemblyFullName$" %>

Step 5: The complete code of visualwebpart1usercontrol.ascx.cs looks like this:

using Microsoft.Office.Server.Search.Administration;

using Microsoft.SharePoint;

using System;

using System.ComponentModel;

using System.Web.UI.WebControls.WebParts;namespace FullCrawlScheduleApp.VisualWebPart1

{

[ToolboxItemAttribute(false)]

public partial class VisualWebPart1 : WebPart{

// Uncomment the following SecurityPermission attribute only when doing Performance Profiling using

// the Instrumentation method, and then remove the SecurityPermission attribute when the code is ready

// for production. Because the SecurityPermission attribute bypasses the security check for callers of

// your constructor, it's not recommended for production purposes.

// [System.Security.Permissions.SecurityPermission(System.Security.Permissions.SecurityAction.Assert, UnmanagedCode = true)]

public VisualWebPart1()

{

}

protected override void OnInit(EventArgs e)

{

base.OnInit(e);InitializeControl();

}

protected void Page_Load(object sender, EventArgs e)

{

TextBox1.Focus();

}

protected void Button1_Click(object sender, EventArgs e)

{

if (string.IsNullOrEmpty(TextBox1.Text) || string.IsNullOrEmpty(TextBox2.Text) || string.IsNullOrEmpty(TextBox3.Text) ||string.IsNullOrEmpty(TextBox4.Text) || string.IsNullOrEmpty(TextBox5.Text) || string.IsNullOrEmpty(TextBox6.Text) ||string.IsNullOrEmpty(TextBox7.Text))

{

Label4.Text = "Please Enter Some Values";

Label4.ForeColor = System.Drawing.Color.Red;

}

else

{

SPSite site = new SPSite("http://win-5c3g1lanj3k:49003/");

SearchContext objSearch = SearchContext.GetContext(site);

DailySchedule objSchedule = new DailySchedule(objSearch);

objSchedule.BeginDay = int.Parse(TextBox3.Text);

objSchedule.BeginMonth = int.Parse(TextBox2.Text);

objSchedule.BeginYear = int.Parse(TextBox4.Text);

objSchedule.StartHour = int.Parse(TextBox5.Text);

objSchedule.StartMinute = int.Parse(TextBox6.Text);

objSchedule.DaysInterval = int.Parse(TextBox7.Text);

Content objContent = new Content(objSearch);

ContentSourceCollection objCollection = objContent.ContentSources;

if (objCollection.Exists(TextBox1.Text))

{

ContentSource objContentSource = objCollection[TextBox1.Text];

objContentSource.FullCrawlSchedule = objSchedule;

objContentSource.Update();

Label4.Text = "Full Crawl Schedule Successfully Configured";

Label4.ForeColor = System.Drawing.Color.Green;

TextBox1.Text = string.Empty;

TextBox2.Text = string.Empty;

TextBox3.Text = string.Empty;

TextBox4.Text = string.Empty;

TextBox5.Text = string.Empty;

TextBox6.Text = string.Empty;

TextBox7.Text = string.Empty;

}

else

{

Label4.Text = "Content Source is not available";

Label4.ForeColor = System.Drawing.Color.Red;

TextBox1.Text = string.Empty;

TextBox2.Text = string.Empty;

TextBox3.Text = string.Empty;

TextBox4.Text = string.Empty;

TextBox5.Text = string.Empty;

TextBox6.Text = string.Empty;

TextBox7.Text = string.Empty;

}

Step 6: Deploy the solution file and add the new webpart to a SharePoint site.

Step 7: The output of the application looks like this:

Step 8: Data entering output of the application looks like this:

Step 9: Full Crawl schedule created output of the application looks like this:
