        function evalue(email) {

           // debugger;

            AtPos = email.indexOf("@")

            StopPos = email.lastIndexOf(".")

            Message = ""

            if (AtPos == -1 || StopPos == -1) {

                Message = "Not a valid email address"

            }

            if (StopPos < AtPos) {

                Message = "Not a valid email address"

            }

            if (StopPos - AtPos == 1) {

                Message = "Not a valid email address"

            }

            if (Message == "")

                return true;

            else

                alert(Message);

    }

        </script>

</head>

Create a Datatable and schema , A new approach

 Hi *.*,

In my last company my senior always use DATATABLE for Binding, i never seen he using DATASET.Difference i seen , by using tables u need to spend more time on coding,On Dataset it finished !!!. But table is fast than set....Any way i used both in my career depending upon needs.Last day my friend introduce me a new approach to Datatables, in one word i'm impressed.Here i'm presenting both.
Old way

    public void _pre()
    {
        try
        {
            DataTable dt = new DataTable("TableName");
            dt.Columns.Add("MyId", typeof(int));
            dt.Columns.Add("Name");
            dt.Columns.Add("Address");
            DataRow dr = new DataRow();
            dr[0] = 1;
            dr[1] = "Arun Aravind";
            dr[2] = "Kollam,Kerala,India";
            dt.Rows.Add(dr);
        }
        catch (Exception)
        {
           
            throw;
        }
    }

New Method

 

    public void _new()
    {
        try
       {
            DataTable dt = new DataTable
            {
                Columns ={
                {"Myid",typeof(int)},
                {"Name"},
                {"Address"}
                }
            };
            dt.Rows.Add(1, "Arun Aravind", "Kollam,Kerala,India");
        }
        catch (Exception)
        {
           throw;
        }
    }

 

Now u compare Both new method is so clean and sexy...Isit???

Hope u got it....Stay Tune...

Getting IP address through JQuery

Hi *.*,

In this tips,show how we could get the client IPAddress  with JQuery. Becase we know to get the client PC IPAddress usign ASP.NET

Using Server Side Code

Request.ServerVariables["REMOTE_ADDR"];

Using Jquery
$(function() {
    $('a').click(function()
{
    $.getJSON("http://jsonip.appspot.com?callback=?",function(ipadd){
        alert( "Your IPAddress is : " + ipadd.ip);
    });
     });
});

in above code,i have done a simple query the IPAddress using JSON to another IPaddress provider server. the callback function will return the Your PC IP Address.

Have a nice day... 'N happy Coding :)
