try this example to Get local computer IP address we will create a new method which will return IP Address

private string GetLocalIP()
 {
 string _IP = null;
 // Resolves a host name or IP address to an IPHostEntry instance.
 // IPHostEntry - Provides a container class for Internet host address information.
 System.Net.IPHostEntry _IPHostEntry = System.Net.Dns.GetHostEntry(System.Net.Dns.GetHostName());
 // IPAddress class contains the address of a computer on an IP network.
 foreach (System.Net.IPAddress _IPAddress in _IPHostEntry.AddressList)
 {
 // InterNetwork indicates that an IP version 4 address is expected
 // when a Socket connects to an endpoint
 if (_IPAddress.AddressFamily.ToString() == "InterNetwork")
 {
 _IP = _IPAddress.ToString();
 }
 }
 return _IP;
 }

Hope this helps

try this example to try many ways to Pass QueryString Parameter with NavigaterUrl in Hyperlink inside a GridView

1-a: Using HyperLinkField of GridView :-

<ASP:GRIDVIEW id=GridView1 runat="server" autogeneratecolumns="False" datakeynames="CustomerID" datasourceid="SqlDataSource1">
 <COLUMNS>
 <ASP:HYPERLINKFIELD text="Detail" datanavigateurlfields="CustomerID" datanavigateurlformatstring="CustomerDetails.aspx?customerId={0}"></ASP:HYPERLINKFIELD>
 <ASP:BOUNDFIELD datafield="CustomerID" headertext="CustomerID" readonly="True" sortexpression="CustomerID"></ASP:BOUNDFIELD>
 <ASP:BOUNDFIELD datafield="CompanyName" headertext="CompanyName" sortexpression="CompanyName"></ASP:BOUNDFIELD>
 <ASP:BOUNDFIELD datafield="ContactName" headertext="ContactName" sortexpression="ContactName"></ASP:BOUNDFIELD>
 </COLUMNS>
</ASP:GRIDVIEW>

<ASP:SQLDATASOURCE id=SqlDataSource1 runat="server" connectionstring="<%$ ConnectionStrings:NORTHWNDConnectionString %>"
selectcommand="SELECT [CustomerID], [CompanyName], [ContactName] FROM [Customers]">
</ASP:SQLDATASOURCE>

1-b: Passing more than one Querystring parameter with HyperLinkField in GridView :-

<asp:hyperlinkfield text="Detail" datanavigateurlfields="CustomerID,CompanyName"
 datanavigateurlformatstring="CustomerDetails.aspx?customerId={0}&amp;companyName={1}" />

2-a: Set NavigateUrl property of HyperLink in TemplateField in Markup :-

<asp:TemplateField>
 <ItemTemplate>
 <asp:HyperLink ID="hlDetails1" Text="Details" runat="server"
 NavigateUrl='<%# "CustomerDetails.aspx?customer=" + Eval("CustomerID") + "&CompanyName=" + Server.UrlEncode(Eval("CompanyName").ToString())%>' />
 </ItemTemplate>
</asp:TemplateField>

2-b: Set NavigateUrl property of HyperLink by Calling method in code-behind:-

<asp:TemplateField>
 <ItemTemplate>
 <asp:HyperLink id="hlDetails2" Text="Details" Runat="server"
 NavigateUrl='<%# GetUrl(Eval("CustomerID"),Eval("CompanyName"))%>' />
 </ItemTemplate>
</asp:TemplateField>

and in code behind add this method

public string GetUrl(object id, object companyname)
 {
 string url = "~/CustomerDetails.aspx?customerid=" + id.ToString() + "&companyname=" +
 Server.UrlEncode(companyname.ToString());
 return url;
 }

2-c: Set NavigateUrl in RowDataBound event :-

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="CustomerID"
DataSourceID="SqlDataSource1" onrowdatabound="GridView1_RowDataBound">
<asp:TemplateField>
 <ItemTemplate>
 <asp:HyperLink id="hlDetails2" Text="Details" Runat="server" />
 </ItemTemplate>
</asp:TemplateField>
</asp:GridView>

and in code behind :-

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
 if (e.Row.RowType == DataControlRowType.DataRow)
 {
 HyperLink hl = (HyperLink)e.Row.FindControl("hlDetails2");
 if (hl != null)
 {
 DataRowView drv = (DataRowView)e.Row.DataItem;
 string id = drv["CustomerID"].ToString();
 string companyname = drv["CompanyName"].ToString();
 hl.NavigateUrl = "~/CustomerDetails.aspx?customerid=" + id.ToString() + "&companyname=" + Server.UrlEncode(companyname.ToString());
 }
 }
}

Hope this helps

try this example to Use WebService with Javascript to Get Auto DateTime

1) open vs2008 and create a new web site and add new WebService name it “WebService.asmx” and add this code :-

using System;
using System.Collections;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Xml.Linq;

/// <summary>
/// Summary description for WebService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
 [System.Web.Script.Services.ScriptService]
public class WebService : System.Web.Services.WebService {

public WebService () {

//Uncomment the following line if using designed components
 //InitializeComponent();
 }

[WebMethod]
 public string GetTime()
 {
 return DateTime.Now.ToString("dd/MM/yyyy hh:mm:ss");
 }

}

2) Add new Web Page and in ASPX Design add this :-

<head runat="server">
 <title>Untitled Page</title>
 <script type="text/javascript" language="javascript">
 var interval = 0;
 function pageLoad() {
 callWebService();
 interval = window.setInterval("callWebService()", 3000);
 }

function callWebService() {
 WebService.GetTime(successCallback, failCallback);
 }

function successCallback(result) {
 var divOutput = document.getElementById("divOutput");
 divOutput.innerHTML = result;
 }

function failCallback(error) {
 alert('Error: ' + error.get_exceptionType());
 }

 </script>
</head>
<body>
 <form id="form1" runat="server">
 <asp:ScriptManager runat="server" ID="scriptManager1">
 <Services>
 <asp:ServiceReference Path="~/WebService.asmx" />
 </Services>
 </asp:ScriptManager>
 <div id="divOutput">
 </div>
 </form>
</body>

then run your page you will find time change every 3 sec this is because i call the result from webservice

Hope this helps

try this example to user Google Weather with ASP.Net

Now we will Create a Method to get Weather for Location

public static void GoogleWeather(string location)
 {
 HttpWebRequest GoogleRequest;
 HttpWebResponse GoogleResponse = null;
 XmlDocument GoogleXMLdoc = null;
 try
 {
 GoogleRequest = (HttpWebRequest)WebRequest.Create("http://www.google.com/ig/api?weather=" + string.Format(location));
 GoogleResponse = (HttpWebResponse)GoogleRequest.GetResponse();
 GoogleXMLdoc = new XmlDocument();
 GoogleXMLdoc.Load(GoogleResponse.GetResponseStream());
 XmlNode root = GoogleXMLdoc.DocumentElement;
 XmlNodeList nodeList1 = root.SelectNodes("weather/forecast_information");
 HttpContext.Current.Response.Write("<B>City : " + nodeList1.Item(0).SelectSingleNode("city").Attributes["data"].InnerText + "</B>");
 XmlNodeList nodeList = root.SelectNodes("weather/current_conditions");
 HttpContext.Current.Response.Write("<TABLE cellPadding=5><TBODY><TR>");
 HttpContext.Current.Response.Write("<TD><B><BIG><NOBR>" + nodeList.Item(0).SelectSingleNode("temp_c").Attributes["data"].InnerText + " °C | " + nodeList.Item(0).SelectSingleNode("temp_f").Attributes["data"].InnerText + " °F</NOBR></BIG></B>");
 HttpContext.Current.Response.Write("<B>Current:</B> " + nodeList.Item(0).SelectSingleNode("condition").Attributes["data"].InnerText + "");
 HttpContext.Current.Response.Write("" + nodeList.Item(0).SelectSingleNode("wind_condition").Attributes["data"].InnerText + "");
 HttpContext.Current.Response.Write(nodeList.Item(0).SelectSingleNode("humidity").Attributes["data"].InnerText);
 nodeList = root.SelectNodes("descendant::weather/forecast_conditions");
 foreach (XmlNode nod in nodeList)
 {
 HttpContext.Current.Response.Write("</TD><TD align=middle>" + nod.SelectSingleNode("day_of_week").Attributes["data"].InnerText + "");
 HttpContext.Current.Response.Write("<IMG alt='" + nod.SelectSingleNode("condition").Attributes["data"].InnerText + "' src='http://www.google.com" + nod.SelectSingleNode("icon").Attributes["data"].InnerText + "'>");
 HttpContext.Current.Response.Write(nod.SelectSingleNode("low").Attributes["data"].InnerText + "°F | ");
 HttpContext.Current.Response.Write(nod.SelectSingleNode("high").Attributes["data"].InnerText + "°F");
 }
 HttpContext.Current.Response.Write("</TD></TR></TBODY></TABLE>");
 }
 catch (System.Exception ex)
 {
 HttpContext.Current.Response.Write(ex.Message);
 }
 finally
 {
 GoogleResponse.Close();
 }
 }

To use this method :-

GoogleWeather("Egypt");

Hope this helps

try this example to use JQuery to Enable and Disable Textbox when CheckBox is Checked with Gridview

1) Open VS2008 and create a new website and add new page and from Toolbox drag Gridview in web page so our page will be like this :-

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
 <Columns>
 <asp:TemplateField HeaderText="Ministry">
 <ItemTemplate>
 <asp:CheckBox ID="CheckBox" runat="server" />
 </ItemTemplate>
 </asp:TemplateField>
 <asp:TemplateField HeaderText="Ministry">
 <ItemTemplate>
 <asp:Label ID="Ministry" runat="server" Text='<%#Eval("Ministry")%>' />
 </ItemTemplate>
 </asp:TemplateField>
 <asp:TemplateField HeaderText="Title">
 <ItemTemplate>
 <asp:Label ID="Title" runat="server" Text='<%#Eval("Title")%>' />
 </ItemTemplate>
 </asp:TemplateField>
 <asp:TemplateField HeaderText="Criteria">
 <ItemTemplate>
 <asp:TextBox ID="Criteria" runat="server" Text='<%#Eval("Criteria")%>' />
 </ItemTemplate>
 </asp:TemplateField>
 </Columns>
 </asp:GridView>

2) Now we need to Bind Grivdview control so in code behind add the following code :-

protected void Page_Load(object sender, EventArgs e)
 {
 string s = Guid.NewGuid().ToString().ToLower();
 var obj = new { Ministry = "Ministry 0", Title = "Title 0", Criteria = "Criteria 0" };
 var objList = (new[] { obj }).ToList();
 objList.Add(new { Ministry = "Minis try 1", Title = "Title 1", Criteria = "Criteria 1" });
 objList.Add(new { Ministry = "Mi nis try sfd 2", Title = "Title 2", Criteria = "Criteria 2" });
 objList.Add(new { Ministry = "Minis try fdsf sdf 3", Title = "Title 3", Criteria = "Criteria 3" });
 objList.Add(new { Ministry = "Mini stryd dd 4", Title = "Title 4", Criteria = "Criteria 4" });
 objList.Add(new { Ministry = "Min is tryf 5", Title = "Title 5", Criteria = "Criteria 5" });
 objList.Add(new { Ministry = "Mini stry 6", Title = "Title 6", Criteria = "Criteria 6" });
 GridView1.DataSource = objList;
 GridView1.DataBind();
 }

3) Now We need to add Jquery function which will enable and disable Textbox in Gridview according to Checkbox state

<script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.5.js" type="text/javascript"></script>
 <script type="text/javascript">
 $(document).ready(function() {
 $("input[type=text][id*=Criteria]").attr("disabled", true);
 $("input[type=checkbox][id*=CheckBox]").click(function() {
 if (this.checked)
 $(this).closest("tr").find("input[type=text][id*=Criteria]").attr("disabled", false);
 else
 $(this).closest("tr").find("input[type=text][id*=Criteria]").attr("disabled", true);
 });
 });

 </script>

Hope this helps

try this example to Encrypt and Decrypt QueryString in Gridview

In this example i will use Northwind Database (Categories and Products tables)

1) Open VS2008 and create new web site

2) Add Web.Config and add the connection string to database

<connectionStrings>
 <add name="NorthwindConnectionString" connectionString="Data Source=.;Initial Catalog=Northwind;Integrated Security=True" providerName="System.Data.SqlClient"/>
 </connectionStrings>

3) Add new Class name it “Encriptor.cs” and add the following code which will Encrypt and Decrypt Querystring :-

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Security.Cryptography;
using System.IO;
using System.Text;

/// <summary>
/// Summary description for Encriptor
/// </summary>
public class Encriptor
{
 public Encriptor()
 {
 }

const string DESKey = "AQWSEDRF";
 public static int key = 129;

public static string Encrypt(string strToEncrypt, string strKey)
 {
 try
 {
 TripleDESCryptoServiceProvider objDESCrypto =
 new TripleDESCryptoServiceProvider();
 MD5CryptoServiceProvider objHashMD5 = new MD5CryptoServiceProvider();
 byte[] byteHash, byteBuff;
 string strTempKey = strKey;
 byteHash = objHashMD5.ComputeHash(ASCIIEncoding.ASCII.GetBytes(strTempKey));
 objHashMD5 = null;
 objDESCrypto.Key = byteHash;
 objDESCrypto.Mode = CipherMode.ECB; //CBC, CFB
 byteBuff = ASCIIEncoding.ASCII.GetBytes(strToEncrypt);
 return Convert.ToBase64String(objDESCrypto.CreateEncryptor().
 TransformFinalBlock(byteBuff, 0, byteBuff.Length));
 }
 catch (Exception ex)
 {
 return "Wrong Input. " + ex.Message;
 }
 }

/// <summary>
 /// Decrypt the given string using the specified key.
 /// </summary>
 /// <param name="strEncrypted">The string to be decrypted.</param>
 /// <param name="strKey">The decryption key.</param>
 /// <returns>The decrypted string.</returns>
 public static string Decrypt(string strEncrypted, string strKey)
 {
 try
 {
 TripleDESCryptoServiceProvider objDESCrypto =
 new TripleDESCryptoServiceProvider();
 MD5CryptoServiceProvider objHashMD5 = new MD5CryptoServiceProvider();
 byte[] byteHash, byteBuff;
 string strTempKey = strKey;
 byteHash = objHashMD5.ComputeHash(ASCIIEncoding.ASCII.GetBytes(strTempKey));
 objHashMD5 = null;
 objDESCrypto.Key = byteHash;
 objDESCrypto.Mode = CipherMode.ECB; //CBC, CFB
 byteBuff = Convert.FromBase64String(strEncrypted);
 string strDecrypted = ASCIIEncoding.ASCII.GetString
 (objDESCrypto.CreateDecryptor().TransformFinalBlock
 (byteBuff, 0, byteBuff.Length));
 objDESCrypto = null;
 return strDecrypted;
 }
 catch (Exception ex)
 {
 return "Wrong Input. " + ex.Message;
 }
 }

public static string decryptQueryString(string stringToDecrypt)//Decrypt the content
 {
 byte[] c = Convert.FromBase64String(stringToDecrypt);
 string decryptedConnectionString = System.Text.UTF32Encoding.UTF32.GetString(c);
 decryptedConnectionString = decryptedConnectionString.Replace("_V_", " ");
 return decryptedConnectionString;
 return stringToDecrypt;
 return Decrypt(stringToDecrypt, DESKey);
 }

public static string Reverse(string str)
 {
 int len = str.Length;
 char[] arr = new char[len];
 for (int i = 0; i < len; i++)
 {
 arr[i] = str[len - 1 - i];
 }
 return new string(arr);
 }

public static string ReverseAdvanced(string str, bool isenc)
 {
 string result = Reverse(str);
 if (!(str.Length < 3))
 {
 for (int i = 0; i < str.Length; i++)
 {
 ShiftMiddle(result, isenc);
 }
 }
 return result;
 }
 public static string encryptQueryString(string stringToEncrypt)// Encrypt the content
 {
 stringToEncrypt = stringToEncrypt.Replace(" ", "_V_");
 byte[] b = System.Text.UTF32Encoding.UTF32.GetBytes(stringToEncrypt);
 string encryptedConnectionString = Convert.ToBase64String(b);
 return encryptedConnectionString;
 return stringToEncrypt;
 return Encrypt(stringToEncrypt, DESKey);
 return stringToEncrypt + "x";
 }

static byte[] Convert2ByteArray(string strInput)
 {
 int intCounter; char[] arrChar;
 arrChar = strInput.ToCharArray();
 byte[] arrByte = new byte[arrChar.Length];

for (intCounter = 0; intCounter <= arrByte.Length - 1; intCounter++)
 arrByte[intCounter] = Convert.ToByte(arrChar[intCounter]);
 return arrByte;
 }
}

4) Add new Web Page and from Toolbox drag Gridview control

<div>
 <asp:GridView ID="GV_Category" runat="server" AutoGenerateColumns="False"
 DataKeyNames="CategoryID" CellPadding="4" ForeColor="#333333">
 <RowStyle BackColor="#FFFBD6" ForeColor="#333333" />
 <Columns>
 <asp:BoundField DataField="CategoryID" HeaderText="CategoryID" ReadOnly="true" InsertVisible="False"
 SortExpression="CategoryID" />
 <asp:BoundField DataField="CategoryName" HeaderText="CategoryName" SortExpression="CategoryName" />
 <asp:BoundField DataField="Description" HeaderText="Description" SortExpression="Description" />
 <asp:TemplateField>
 <ItemTemplate>
 <a href="#" onclick="window.open('Product_Detail.aspx?CategoryID=<%# Encriptor.encryptQueryString(DataBinder.Eval(Container.DataItem,"CategoryID").ToString())%>'); return false">Products Detail</a>
 </ItemTemplate>
 </asp:TemplateField>
 </Columns>
 <FooterStyle BackColor="#990000" Font-Bold="True" ForeColor="White" />
 <PagerStyle BackColor="#FFCC66" ForeColor="#333333" HorizontalAlign="Center" />
 <SelectedRowStyle BackColor="#FFCC66" Font-Bold="True" ForeColor="Navy" />
 <HeaderStyle BackColor="#990000" Font-Bold="True" ForeColor="White" />
 <AlternatingRowStyle BackColor="White" />
 </asp:GridView>
 </div>

5)  Now we want to bind that Gridview to Categories table so in code behind we will add the following code :-

protected void Page_Load(object sender, EventArgs e)
 {
 if (!IsPostBack)
 {
 SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString);
 SqlCommand comm = new SqlCommand("Select * from Categories", conn);
 DataSet ds = new DataSet();
 SqlDataAdapter adpter = new SqlDataAdapter(comm);
 adpter.Fill(ds);
 GV_Category.DataSource = ds;
 GV_Category.DataBind();
 }
 }

Don’t forget to use the following Namespace

using System.Data.SqlClient;

6) Add Another Web Page called “Product_Detail.aspx” and from Toolbox drag Gridview control to bind Products for each Category using Querystring

<div>
 <asp:GridView ID="gvProducts" runat="server"
 CssClass="datagrid" AutoGenerateColumns="False"
 DataKeyNames="ProductID" CellPadding="4" ForeColor="#333333">
 <RowStyle BackColor="#FFFBD6" ForeColor="#333333" />
 <Columns>
 <asp:BoundField DataField="ProductID" HeaderText="ProductID" ReadOnly="true"
 InsertVisible="False" SortExpression="ProductID" />
 <asp:BoundField DataField="ProductName" HeaderText="ProductName"
 SortExpression="ProductName" />
 <asp:BoundField DataField="QuantityPerUnit" HeaderText="QuantityPerUnit"
 SortExpression="QuantityPerUnit" />
 <asp:BoundField DataField="UnitPrice" HeaderText="UnitPrice"
 SortExpression="UnitPrice" />
 </Columns>
 <FooterStyle BackColor="#990000" Font-Bold="True" ForeColor="White" />
 <PagerStyle BackColor="#FFCC66" ForeColor="#333333" HorizontalAlign="Center" />
 <SelectedRowStyle BackColor="#FFCC66" Font-Bold="True" ForeColor="Navy" />
 <HeaderStyle BackColor="#990000" Font-Bold="True" ForeColor="White" />
 <AlternatingRowStyle BackColor="White" />
 </asp:GridView>
 </div>

7) In Code behind we will add the following Code :-

protected void Page_Load(object sender, EventArgs e)
 {
 if (!IsPostBack)
 {
 SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString);
 SqlCommand comm = new SqlCommand("Select * from Products where CategoryID = @CategoryID", conn);
 comm.Parameters.Add("@CategoryID", SqlDbType.Int).Value = Encriptor.decryptQueryString(Request.QueryString["CategoryID"]);
 DataSet ds = new DataSet();
 SqlDataAdapter adpter = new SqlDataAdapter(comm);
 adpter.Fill(ds);
 gvProducts.DataSource = ds;
 gvProducts.DataBind();
 }
 }

Hope this helps

Good Luck

try this example to use JQuery and Google to create currency converter with ASP.Net

1) Open VS2008 and create a new web site and add new WebService called “WebService.asmx”

try this example to Get All logged in users using Membership :-

First Add Gridview Control in your page and in code behind add this code which will bind Gridview to Online Users :-

  ArrayList list = new ArrayList();
        MembershipUserCollection allUsers = Membership.GetAllUsers();
        MembershipUserCollection filteredUsers = new MembershipUserCollection(); 
        bool isOnline = true;
        foreach (MembershipUser user in allUsers)
        {
            // if user is currently online, add to gridview list
            if (user.IsOnline == isOnline)
            {
                filteredUsers.Add(user);
                list.Add(user);
            } 
            gvwonlineusers.DataSource = list;
            gvwonlineusers.DataBind();
        }

Hope this helps
