URLReferrer - If blank my code crashes

How do I fix this?

[chris_f]

Hi,

My code simply reads

Dim PageReferrer As String
PageReferrer = Request.UrlReferrer.ToString

This works fine if there is a referrer. However, if there is no referrer I get the following error message.

Object reference not set to an instance of an object.

I have tried several ways of fixing this including:

Dim PageReferrer As String
If Request.UrlReferrer.ToString Is Null Then
PageReferrer = "NULL"
Else
PageReferrer = Request.UrlReferrer.ToString
End If

The problem with this is that 'Is Null' is no longer used. Can someone help me find a way around this please. I am using VB.net to build an ASP.net web application.

Don't you just love me Xoc. I promise this is the last time ;)

Thanks In Advanced
Chris.

Got it working. My If statement should have been

If Not Request.UrlReferrer Is Nothing Then
