What are you doing when a user logs on? setting session variables / creating cookies?

You could write a little class (or user control) that checks the session variables / cookies, and if not found, redirect to an 'access denied' page, then just import this into every page.

Shouldn't be too hard

Can u please give me the coding for that access-denied page.... Its urgent for me.. I need to complete my project today... Tell me the correct procedure to redirect to acess denied page...

Tell me the correct procedure to redirect to acess denied page...

Only because I am feeling sorry for ya, and have been in your situation myself.. You can save yourself this stress by managing your time a little better.

When your user logs in successfully, set a session variable called UserOk = True. Then you can either add this sub into each page and call it from the Form_Load i.e
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
CheckUser()
End If
End Sub

Sub CheckUser()
Dim IsUserOk as Object = session("UserOK")
If (IsUserOk is Nothing) OR (IsUserOk = False) Then
Response.Redirect("accessdenied.htm")
End If
End Sub

or a better way is to have this in a class...

good luck
