using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;

{
Hashtable schedule = new Hashtable();
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
string[] data = (string[])Application["msg"];
int i = 0;
for (i = data.Length - 1; i > 0; i--)
{
if (data[i] == "")
break;
data[i] = data[i - 1];
}
data[i] = "<strong> Welcome " + TextBox1.Text + " :</strong> ";
Session["name"] = "<strong> "+
TextBox1.Text + "</strong> ";
Server.Transfer("Default2.aspx");
}

{
// Code that runs when an unhandled error occurs
}
void Session_Start(object sender, EventArgs e)
{
string name = "";
}
void Session_End(object sender, EventArgs e)
{
// Code that runs when a session ends.
// Note: The Session_End event is raised only when the sessionstate mode
// is set to InProc in the Web.config file. If session mode is set to StateServer
// or SQLServer, the event is not raised.
