ASP.NET Session Variables

Asked by crich in Programming for ASP.NET, Microsoft Programming

Tags: ,

Hi there,
 I have the following code on my page to try and retreive the value of a log in session variable:

<script runat="server">
Sub Page_Load (s as object, e as eventargs)
Dim objChkUsername As String
Dim edit As Integer
objChkUsername = Session("chkusername").ToString()
If objChkUsername Is Nothing Then
edit = 0
Else edit = 1
End If
End Sub
</script>

I get the following error though:

[NullReferenceException: Object reference not set to an instance of an object.]

   ASP.index_aspx.Page_Load(Object s, EventArgs e) in D:\inetpub\wwwroot\moorfieldsresearch.org.uk\process\index.aspx:6
   System.Web.UI.Control.OnLoad(EventArgs e) +67
   System.Web.UI.Control.LoadRecursive() +35
   System.Web.UI.Page.ProcessRequestMain() +750

Can anyone suggest where i am going wrong as i am new to asp.net and can't find any simple enough information on the net!

Thanks,
Richard
