create a session like this

session("MySessionName") = me.txtUsername

you can then use this session in other or same page by calling like this

me.txtUsername = session("MySessionName")

have a look here gives a good overview on the session object

Hi,

First you need to have a login table to store user data like userid and username.

In the login page create a

session["userid"].

In this session assign the user name from login table when a user logs in and check this session in every page of your webiste like this

if(Session["username"].TOstring()=="")
response.redirect("login.aspx");

In this way you can redirect user who didnt login to login page.

have a look here
http://www.w3schools.com/ASP/asp_sessions.asp

it shows you how to create and set sessions.

You can set the sessions with the username of the person who logs in.

Use this session in your your page_load events on your pages in the site to check if it exists. if it doesnt, then they have not logged in (the session isnt there and hasnt been created yet) so redirect back to the login page with response.redirect!

hope that helps

ok on my login page i put

Session("UserName") = Request("txtUserName")
            'Session.Timeout = 5
            Response.Redirect("default.aspx")

then on my default page i put

If (Session("UserName") Is Nothing) Then
            Response.Redirect("login.aspx")
        End If

it works..but now the problem is that once login and that the user is directed to the default.aspx page, if login.aspx is typed in the address bar, it bring me to login.aspx page which is wrong...any solution?

at the top of you login page

if Session("UserName") <> ""  Then
 Response.Redirect("default.aspx")
End If
