Declare a Custom Validator;

<asp:CustomValidator runat="server" ID="cvBody" SetFocusOnError="true" Display="dynamic" Text="The Body is required" ClientValidationFunction="ValidateContentText"></asp:CustomValidator>

Add this Javascript function to your page

function ValidateContentText(source,args)
{
var fckBody= FCKeditorAPI.GetInstance('<%=FCKeditor1.ClientID %>');
args.IsValid = fckBody.GetXHTML(true) != "";
}

That means, the administrator of a web application can determine, what all controls are to be displayed in the user-side. Very useful article to begin with.

Creating a Dynamic Data-Driven User Interface

I would recommend all of those who are working on ASP.Net application to read this:

Before importing, you should create a table to receive the data that the SqlBulkCopy class process. Here in this example we will use a table “DummyEmails” to receive the data. The XML file which we use to import is “Email.xml”.

try
{
DataSet xmlDS = new DataSet();
xmlDS.ReadXml(Server.MapPath("Email.xml")); //Name of the XML file

//Create the connection object
SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings[ "LMSConnectionString"].ToString());


//Creating the SqlBulkCopy object
SqlBulkCopy sqlBC = new SqlBulkCopy(connection);


//Specify the destination database table name
sqlBC.DestinationTableName = "DummyEmails";

//If the destination database table's column names doesn't match with the XML element names,
//then we have to relate the XML elements and the table column name.
//For that you can use the below code;
//sqlBC.ColumnMappings.Add("EmailId", "Email_id");
//sqlBC.ColumnMappings.Add("EmailAddress", "Email_Address");
//1st Parameter:Source Column, 2nd Parameter:Destination Column
//You may use the Column index too

connection.Open();
sqlBC.WriteToServer(xmlDS.Tables[0]);

connection.Close();
}
catch { }

The SqlBulkCopy class can be used to write data only to SQL Server tables. However, the data source is not limited to XML file; any data source can be used, as long as the data can be loaded to a DataTable instance or read with a IDataReader instance.

In this example, I had populated a dropdownlist with the tables in a database. Then I choose a table from the list, which needs to be generated as a XML file.

Listing all the tables in the Database

We will generate the XML file in the ‘SelectedIndexChanged’ event of the DropDownList.

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
try
{
DataSet ds = new DataSet();
//Create the connection object
SqlConnection sqlConn = new SqlConnection(ConfigurationManager.ConnectionStrings[ "LMSConnectionString"].ToString());


string strQuery = "Select * from " + DropDownList1.SelectedItem.Text;


SqlCommand sqlCmd = new SqlCommand(strQuery, sqlConn);
SqlDataAdapter sqlAdptr = new SqlDataAdapter(sqlCmd);
sqlAdptr.Fill(ds);


XmlDataDocument doc = new XmlDataDocument(ds);


doc.Save(MapPath(DropDownList1.SelectedItem.Text+".xml")); //The name of the XML file to be generated
}
catch{ }
}

The above code will generate an XML file with the same name of the database table selected, in the root directory.

Easy as 1-2-3

1. Select type of indicator, background color and foreground color.
2. Generate the image.
3. Download the generated image.

The homepage is crisp and clear and the image will change daily. The Bing interface is refreshingly clean and results are displayed by helpful categories. For example, I type books and results are grouped by History, Electronic, Best Sellers, Publishing and Writing. “Simple Organized System, thats Bing”

The Indian version currently doesn’t have the full functionality.

The Indian version doesn’t Have Search History And The Image On The Bing Home Page Here Is Not Interactive As In The Us Version To Explore The Full Version Of Bing. You can change the Indian version to the US version by clicking on the ‘India’ link at the top right of the page and selecting the United States from the country list.

Some of the interesting features that you will notice at first glance:

When you hover on a search result, you will see the orange icon – which gives you a quick preview of the site (text preview). Very useful, if you are still not sure of clicking.

Just search for any video on Bing Videos and hover the mouse over any of the video thumbnail to watch a short clip.(WOW!)

Bing is such a decision engine. It provides an easy way to make more informed choices. It organizes popular results by category to help you get the answers you’re looking for without having to guess at the right way to formulate your query.

In the aspx page;

<body>
    <form id="form1" runat="server">
    <div>
        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="true">
        </asp:GridView>
    </div>
    </form>
</body>

In the aspx.cs page;

using System.Data.OleDb;

    protected void Page_Load(object sender, EventArgs e)
    {
        string strConn = "Provider=Microsoft.ACE.OLEDB.12.0;data source=E:/DummyProject/Excel/Contacts.xlsx;Extended Properties=Excel 12.0;";
        OleDbConnection objConn = new OleDbConnection(strConn);
        //You must use the $ after the object you refer in the spreadsheet
        string strSql = "Select * From [Sheet1$]";
        OleDbCommand objCmd = new OleDbCommand(strSql, objConn);
        try
        {
            objConn.Open();
            GridView1.DataSource = objCmd.ExecuteReader();
            GridView1.DataBind();
        }
        catch (Exception exc)
        {
            Response.Write(exc.ToString());
        }
        finally
        {
            objConn.Dispose();
        }
    }

As you see in the connection string ‘Microsoft.ACE.OLEDB.12.0′ is the new Access database engine OLE DB driver and is also capable of reading Excel 2003. For older versions of excel files, you can use the connection string ‘Provider=Microsoft.Jet.OLEDB.4.0;Data Source=E:/DummyProject/Excel/Contacts.xls;Extended Properties=Excel 8.0′

After some googling I found the reason: ‘With IIS 6.0, Microsoft changed the way streaming media is handled. Previous versions of IIS did not require any modification to stream Flash Video. Microsoft IIS 6.0, the default web server that ships with Windows 2003, requires a MIME type to recognize that FLV files are streamed media.’
To overcome the above difficulties just follow the blow steps;

1. On the Windows 2003 server, open the Internet Information Services Manager.
2. Expand the Local Computer Server.
3. Right-click the local computer server and select Properties.
4. Select the MIME Types tab.
5. Click New and enter the following information:
    o Associated Extension box: .FLV
    o MIME Type box:flv-application/octet-stream
6. Click OK.
7. Restart the World Wide Web Publishing service.

Note: These files work correctly if tested on other operating systems. The issue affects all FLV files played via Windows 2003 server, including files made with the Flash Video Kit for Dreamweaver MX 2004.
