Free ASP.NET Hosting - HostForLIFE.eu :: How to Discover if Linked List contains Loops or Cycles in C# ?

April 17, 2015 07:11 by author

In this post i will be able to show you how to discover loop in linked list with ASP.NET C#. We can notice the loop within the coupled list via Floyd’s Cycle-Finding formula, explained here. The method is pretty simple: We have a tendency to begin at the start of the linked list with 2 pointers. The primary pointer is incremented through every node of the list. The second pointer moves twice as quick, and skips each other node. If the coupled list contains a loop, these 2 pointers can eventually meet at the same node, so indicating that the linked list contains a loop.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Algo
{
    public class Node
    {
        public Node Next { get; set; }
        public int Value { get; set; }
        public Node(int value)
        {
            this.Value = value;
        }
    }
    public class LinkedList
    {
    private Node _head;
        public LinkedList()
        {
        }
        public void AppendLast(Node newNode)
        {
            if (_head == null)
            {
                _head = newNode;
            }
            else
            {
                Node current = _head;
                while (current.Next != null)
                {
                    current = current.Next;
                }
                current.Next = newNode;
            }
        }
        public override string ToString()
        {
            Node current = _head;
            StringBuilder builder = new StringBuilder();
            while (current != null)
            {
                builder.Append(current.Value + "->");
                current = current.Next;
            }
            return builder.ToString();
        }
        public bool IsCycle()
        {
            Node slow = _head;
            Node fast = _head;
            while (fast != null && fast.Next != null)
            {
                fast = fast.Next.Next;
               slow = slow.Next;
                if (slow == fast)
                    return true;
            }
            return false;
        }
    }
    class Program
    {
        static void Main(string[] args)
        {
            LinkedList list = new LinkedList();
            list.AppendLast(new Node(10));
            list.AppendLast(new Node(20));
            list.AppendLast(new Node(30));
            Node cycle = new Node(40);
            list.AppendLast(cycle);
            list.AppendLast(new Node(60));
            list.AppendLast(cycle);
             if (list.IsCycle())
            {
                Console.WriteLine("Linked List is cyclic as it contains cycle or loop");
            }
            else
            {
                Console.WriteLine("LinkedList is not cyclic, no loop or cycle found");
            }

FREE ASP.NET Hosting – HostForLIFE.eu :: Displaying SubTotal & Grand Total in ASP.NET 5

April 13, 2015 12:17 by author

Peter

In this tutorial, I will show you how to Displaying SubTotal & Grand Total in ASP.NET 5. First, create new project. The records are isolated into Groups and after that SubTotal is calculated for every Group and then shown utilizing an element Row as a part of GridView. Now , I write the following code to create Products table:

CREATE TABLE [dbo].[Products](
     [ProductID] [int] NULL,
     [ProductName] [varchar](100) NULL,
     [CategoryID] [int] NULL,
     [UnitPrice] [decimal](18, 0) NULL,
     [QuantityPerUnit] [varchar](100) NULL
) ON [PRIMARY]
GO

First create new web apps and open your GridViewSubTotalTotal.aspx and write the following code:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title> Displaying SubTotal & Grand Total in ASP.NET 5</title>
</head>
<body>
    <form id="form1" runat="server">
    <h3 style="color:Green">Display SubTotal and Grand Total in ASP.Net GridView</h3>
    <div>
        <asp:GridView ID="gvData" runat="server" BackColor="White" BorderColor="#CC9966"
            AutoGenerateColumns="false" BorderStyle="Solid" BorderWidth="1px" CellPadding="4"
            Font-Names="Tahoma" Font-Size="Small" Width="475px" OnRowCreated="gvData_RowCreated"
nDataBound="gvData_OnDataBound">
            <Columns>
                <asp:BoundField DataField="ProductID" HeaderText="ProductID" />
                <asp:BoundField DataField="CategoryID" HeaderText="Category ID" />
                <asp:BoundField DataField="ProductName" HeaderText="ProductName" />
                <asp:BoundField DataField="Price" HeaderText="Price" DataFormatString="{0:N2}"/>
            </Columns>
            <FooterStyle BackColor="Tan" />
            <AlternatingRowStyle BackColor="#E6E6E1" />
            <FooterStyle BackColor="#FFFFCC" ForeColor="#330099" />
            <HeaderStyle BackColor="#990000" Font-Bold="True" ForeColor="#FFFFCC" />
        </asp:GridView>
    </div>
    </form>
</body>
</html>

Next step, write the code below: GridViewSubTotalTotal.aspx.cs:
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
using System.Drawing;
public partial class GridViewSubTotalTotal : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
   {
        if (!IsPostBack)
        {
            BindGridData();
        }
    }
    protected void BindGridData()
    {
        SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConString"].ConnectionString);
        string sqlQuery = "SELECT ProductID,ProductName,CategoryID,(UnitPrice*QuantityPerUnit) AS Price FROM Products";
        sqlQuery = sqlQuery + " WHERE CategoryID in(1,2,3) ORDER BY ProductID ASC";
        SqlCommand cmd = new SqlCommand(sqlQuery, con);
        SqlDataAdapter da = new SqlDataAdapter(cmd);
        DataSet ds = new DataSet();
        da.Fill(ds);
        gvData.DataSource = ds;
        gvData.DataBind();
}
    int currentId = 0;
    decimal subTotal = 0;
    decimal total = 0;
    int subTotalRowIndex = 0;
    protected void gvData_RowCreated(object sender, GridViewRowEventArgs e)
    {
        subTotal = 0;
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            DataTable dt = (e.Row.DataItem as DataRowView).DataView.Table;
            int ProductID = Convert.ToInt32(dt.Rows[e.Row.RowIndex]["ProductID"]);
            total += Convert.ToDecimal(dt.Rows[e.Row.RowIndex]["Price"]);
            if (ProductID != currentId)
            {
                if (e.Row.RowIndex > 0)
                {
                    for (int i = subTotalRowIndex; i < e.Row.RowIndex; i++)
                    {
                        subTotal += Convert.ToDecimal(gvData.Rows[i].Cells[3].Text);
                    }
                    this.AddTotalRow("Sub Total", subTotal.ToString("N2"));
                    subTotalRowIndex = e.Row.RowIndex;
                }
                currentId = ProductID;
            }
        }
    }
    private void AddTotalRow(string labelText, string value)
    {
        GridViewRow row = new GridViewRow(0, 0, DataControlRowType.DataRow, DataControlRowState.Normal);
        row.BackColor = ColorTranslator.FromHtml("#FFA500");
        row.Cells.AddRange(new TableCell[4] {new TableCell { Text = labelText, HorizontalAlign = HorizontalAlign.Right},
new TableCell (),
new TableCell(), //Empty Cell,
new TableCell { Text = value, HorizontalAlign = HorizontalAlign.Right }
);
        row.Cells[0].BorderColor = System.Drawing.Color.Orange;
        row.Cells[1].BorderColor = System.Drawing.Color.Orange;
        row.Cells[2].BorderColor = System.Drawing.Color.Orange;
        row.Cells[3].BorderColor = System.Drawing.Color.Orange;
        gvData.Controls[0].Controls.Add(row);
    }
    protected void gvData_OnDataBound(object sender, EventArgs e)
    {
        for (int i = subTotalRowIndex; i < gvData.Rows.Count; i++)
        {
            subTotal += Convert.ToDecimal(gvData.Rows[i].Cells[3].Text);
        }
        this.AddTotalRow("Sub Total", subTotal.ToString("N2"));
        this.AddTotalRow("Total", total.ToString("N2"));
    }
}

I hope this tutorial works for you!

ASP.NET 5 Hosting - HostForLIFE.eu :: On Page Connection with ASP.NET 5

April 10, 2015 07:46 by author

Peter

ASP.NET will gives you adaptability by they way you connect with databases. It would be ideal if you include the following code in your aspx page and check how to get connection on .aspx page. And here is the code that I used:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="onpageconnection.aspx.cs" Inherits="onpageconnection" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        try
        {
            System.Data.SqlClient.SqlConnection con;
            sqlconn objconn = new sqlconn();
            con = objconn.getcon();
            con.Open();
            String str = "select * from EmpDemo";
            //SqlCommand cmd = new SqlCommand(str,con);
            //SqlDataReader adp;
            SqlDataAdapter adp = new SqlDataAdapter(str,con);
                        DataSet ds = new DataSet();
            adp.Fill(ds);
            GridView1.DataSource = ds;
            GridView1.DataBind();
            //Response.Write("connection open");
}
        catch (Exception ex)
        {
            Response.Write(ex.Message);

ASP.NET 5 Hosting - HostForLIFE.eu :: Anti Forgery Tokens with AngularJS and ASP.NET 5

March 23, 2015 12:10 by author

Peter

In this post, I will tell you about Anti Forgery Tokens with AngularJS and ASP.NET 5. Single Page Applications utilizing AngularJS with ASP.NET by default leave our Web API methods open to forgery abuse. A couple of straightforward steps will permit you to include hostile to phony security. The primary step will be to make a custom activity channel ascribe to test our answer which you can use to finish web programming interface classes or individual activities.

using System;
using System.Linq;
using System.Net.Http;
using System.Web.Helpers;
using System.Web.Http.Filters;
namespace antiforgery
{
    public sealed class ValidateCustomAntiForgeryTokenAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(System.Web.Http.Controllers.HttpActionContext actionContext)
       {
           if (actionContext == null)
            {
                throw new ArgumentNullException("actionContext");
            }
            var headers = actionContext.Request.Headers;
            var cookie = headers
                .GetCookies()
                .Select(c => c[AntiForgeryConfig.CookieName])
                .FirstOrDefault();
            var tokenFromHeader = headers.GetValues("X-XSRF-Token").FirstOrDefault();
            AntiForgery.Validate(cookie != null ? cookie.Value : null, tokenFromHeader);
            base.OnActionExecuting(actionContext);
        }
    }
}

The web API classes or methods will need decorating appropriately to ensure this code is run, i.e.
[ValidateCustomAntiForgeryTokenAttribute]

The following step is to verify ASP.NET includes its standard forgery token cookie and hidden field in the markup. Include the accompanying line into the markup.
@Html.AntiForgeryToken();

Presently, we have to redesign our AngularJS code to pass anti forgery token back in the header with all our web API calls. The most straightforward approach to do this is to situated a default up in the run system for the AngularJS application module, e.g.
.run(function($http) {
    $http.defaults.headers.common['X-XSRF-Token'] =
angular.element('input[name="__RequestVerificationToken"]').attr('value');
})

ASP.NET 5 Hosting - HostForLIFE.eu :: Custom Config Section in ASP.NET

March 20, 2015 08:18 by author

Peter

In this post, I will tell you how to extend ASP.NET 5 configuration settings with XML configuration elements of your own. To do this, you make a custom configuration section handler. The handler must be a .NET Framework class that inherits from the System.Configuration.ConfigurationSection class. The area handler translates and forms the settings that are characterized in XML design components in a particular area of a Web.config file. You can read and write these settings through the handler's properties.

And now, write the following code:
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Linq;
using System.Web;
namespace CustomConfigSection
{
    public class LoginRedirectByRoleSection : ConfigurationSection
    {
        [ConfigurationProperty("roleRedirects")]
    public RoleRedirectCollection RoleRedirects
        {
    get
            {
    return (RoleRedirectCollection)this["roleRedirects"];
            }
    set
            {
    this["roleRedirects"] = value;
            }
        }
    }
    public class RoleRedirect : ConfigurationElement
   {
       [ConfigurationProperty("role", IsRequired = true)]
    public string Role
        {
    get
            {
    return (string)this["role"];
            }
    set
            {
    this["role"] = value;
            }
        }
        [ConfigurationProperty("url", IsRequired = true)]
    public string Url
        {
    get
            {
    return (string)this["url"];
            }
    set
            {
    this["url"] = value;
            }
        }
    }
    public class RoleRedirectCollection : ConfigurationElementCollection
    {
    public RoleRedirect this[int index]
        {

            }
        }
    public RoleRedirect this[object key]
        {
    get
            {
    return (RoleRedirect)BaseGet(key);
            }
        }
    protected override ConfigurationElement CreateNewElement()
        {
    return new RoleRedirect();
        }
    protected override object GetElementKey(ConfigurationElement element)
        {
    return ((RoleRedirect)element).Role;
        }
    }
}
<configSections>
    <section name="loginRedirectByRole" type="CustomConfigSection.LoginRedirectByRoleSection,CustomConfigSection" allowLocation="true" allowDefinition="Everywhere" />
   </configSections>
    <loginRedirectByRole>
    <roleRedirects>
    <add role="Administrator" url="~/Admin/Default.aspx" />
    <add role="User" url="~/User/Default.aspx" />
    </roleRedirects>
    </loginRedirectByRole>

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;

ASP.NET 5 Hosting UK - HostForLIFE.eu :: How to Capture Screenshot Image of Website in ASP.NET 5?

March 16, 2015 07:42 by author

Peter

In this short article, I will tell you about How to Capture Screenshot Image of Website in ASP.NET 5. To catch the screenshot of page, I am making utilization of WebBrowser control of Windows Forms Application. Since the WebBrowser is a Windows Forms controls, so as to utilize it as a part of ASP.NET Web Projects, we will need to add reference to the accompanying libraries.

And here is the code that I used:

ASP.NET
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title> How to Capture Screenshot in ASP.NET</title>
</head>
<body>
    <form id="form1" runat="server">
    <table>
        <tr>
            <td>
                <b>Enter WebSite Url:</b>
            </td>
            <td>
                <asp:TextBox ID="txtUrl" runat="server" />
            </td>
        </tr>
        <tr>
            <td>
            </td>
            <td>
                <asp:Button ID="btnCapture" Text="Capture" runat="server" OnClick="btnCapture_click" />
            </td>
        </tr>
    </table>
    <br />
    <asp:Image ID="imgScreenshot" runat="server" Visible="false" Height="800" Width="800" />
    </form>
</body>
</html>

Code for C#
using System.IO;
using System.Drawing;
using System.Threading;
using System.Windows.Forms;
public partial class CaptureWebsite : System.Web.UI.Page
{
    protected void btnCapture_click(object sender, EventArgs e)
   {
        string url = txtUrl.Text.Trim();
        Thread thread = new Thread(delegate()
       {
            using (WebBrowser browser = new WebBrowser())
            {
                browser.ScrollBarsEnabled = false;
                browser.AllowNavigation = true;
               browser.Navigate(url);
                browser.Width = 1024;
                browser.Height = 768;
                browser.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webbrowse_DocumentCompleted);
                while (browser.ReadyState != WebBrowserReadyState.Complete)
                {
                    System.Windows.Forms.Application.DoEvents();
                }
            }

ASP.NET 5 Hosting Russia - HostForLIFE.eu :: Submit Form Without Page Refresh in ASP.NET with Ajax and jQuery

March 9, 2015 08:06 by author

Peter

In this short tutorial, I will tell you about submit form without page refresh in ASP.NET with Ajax and jQuery. First step, make a Employee table as shown on the picture below:

Now, make a new WebSite then add a new WebForm name as Index.aspx. Write the following code to the page.

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Index.aspx.cs" Inherits="Index" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script src="Script/jquery-2.1.1.min.js"></script>
    <script src="Script/Myjs.js"></script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <table>
            <tr>
                <td>Name</td>
                <td>
                    <input type="text" id="txtName" />
                </td>
            </tr>
           <tr>
                <td>Age</td>
                <td>
                    <input type="text" id="txtAge" />
                </td>
            </tr>
            <tr>
                <td>Email</td>
                <td>
                    <input type="text" id="txtEmail" />
                </td>
            </tr>
            <tr>
                <td>
                    <input type="button" id="btnSubmit" value="Save" />
                </td>
            </tr>
        </table>
        <label id="lblResult" ></label>
    </div>
    </form>
</body>
</html>

Now, Open file Index.aspx.cs and write the following code:
using System;
using System.Web.Services;
using System.Data.SqlClient;
public partial class Index : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
     }
     [WebMethod]
    public static string SaveRecord(string Name,int Age, string Email)
    {
        string messageResult = string.Empty;
        string strConnection = @"Data Source=(LocalDB)\v11.0;AttachDbFilename=C:\Users\Peter\TestDB.mdf;Integrated Security=True;Connect Timeout=30";
        SqlConnection con = new SqlConnection(strConnection);
        con.Open();
        SqlCommand cmd = new SqlCommand("insert into Employee (Name,Age,Email) values (@name,@age,@email)",con);
        cmd.Parameters.AddWithValue("@name", Name);
        cmd.Parameters.AddWithValue("@age",Age);
        cmd.Parameters.AddWithValue("@email", Email);
        int result = cmd.ExecuteNonQuery();
        con.Close();
        if(result == 1)
        {
            messageResult = "Record Inserted";
        }
        else
        {
            messageResult="Unable to Save Record";
        }
        return messageResult;
    }
}

Above you can see, I have included a attribute [WebMethod]. What is WebMethod ? A WebMethod Attribute Enable a system to be called through the WebServices. Now, include another JS record. Compose the accompanying code in your JS document.
$(document).ready(function () {
    $('#btnSubmit').on('click', function () {
        var getName = $('#txtName').val();
        var getAge = parseInt($('#txtAge').val());
        var getEmail = $('#txtEmail').val();
        $.ajax(
            {
                type: "POST",
                contentType: "application/json; charset=utf-8",
                url: "Index.aspx/SaveRecord",
                data: "{'Name':'" + getName + "','Age':" + getAge + ",'Email':'" + getEmail + "'}",
                dataType: "json",
                success:function(data)
                {
                    $('#lblResult').text(data.d);
                    $('#txtName').val('');
                    $('#txtAge').val('');
                    $('#txtEmail').val('');
                },
                error:function(data)
                {
                    alert(data);
               }
            });

});
});

And here is the output:

ASP.NET 5 Hosting - HostForLIFE.eu :: Create Web API, Run Outside IIS Application

March 6, 2015 06:22 by author

Peter

Today, In this article I will tell you about Create Web API with ASP.NET 5, run outside IIS application. First step, open visual studio and then make a console application as you can see on the picture below:

Create the Web API & OWIN Packages
Go to Tools menu, choose Library Package Manager, then select Package Manager Console. In the Package Manager Console window, enter the following code:
Install-Package Microsoft.AspNet.WebApi.OwinSelfHost

Then, right click the project. Create new class named Startup.cs and add the following code:
public class Startup
   {
        // This code configures Web API. The Startup class is specified as a type
        // parameter in the WebApp.Start method.
        public void Configuration(IAppBuilder appBuilder)
        {
            // Configure Web API for self-host.
           HttpConfiguration config = new HttpConfiguration();
            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );
             appBuilder.UseWebApi(config);
        }
    }

Now create a Web API controller class. In Solution Explorer, right click the project & choose Add / Class to add a new class. I named it: HelloController. Then write the following code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Web.Http;
namespace SelfHostWebApi
{
    public class HelloController : ApiController
    {
        // GET api/values/5
        public string Get(int id)
        {
            return "Hello API";
        }
    }
}

Open Program.cs and add write the code below, inside main method:
using Microsoft.Owin.Hosting;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;
namespace SelfHostWebApi
{
    class Program
    {
        static void Main(string[] args)
        {
            string baseAddress = "http://localhost:9000/";
            // Start OWIN host
            using (WebApp.Start<Startup>(url: baseAddress))
            {
               // Create HttpCient and make a request to api/values
                HttpClient client = new HttpClient();
                var response = client.GetAsync(baseAddress + "api/hello").Result;
                Console.WriteLine(response);
                Console.WriteLine(response.Content.ReadAsStringAsync().Result);
            }
            Console.ReadLine();
        }    }
}

Finally, your self hosted Web API is ready. You will see the output like the picture below when you Run it.
