"system.nullreferenceexception" error

[mcarten]

I'm getting the dreaded "nullreferenceexception" error with this code.

In an ASP application it works fine.
In VB Express 2005 it does not.

These are my imports ....

Imports System
Imports System.Net
Imports System.Net.IPAddress
Imports System.Net.Dns
Imports System.Net.Sockets
Imports Microsoft.VisualBasic
Imports System.Collections
Imports System.Configuration
Imports System.Data
Imports System.Web
Imports System.Management
Imports System.Web.SessionState

        Dim ipaddr As String
 
        If System.Web.HttpContext.Current.Request.ServerVariables("REMOTE_ADDR") Is DBNull.Value Then
            MsgBox("Null")
        Else
            ipaddr = System.Web.HttpContext.Current.Request.ServerVariables("REMOTE_ADDR")
        End If
 

Please HELP!
