    Posted: 06 August 2003 at 3:21pm

I am building a asp.net web application in Visual Basic .NET and want to compare data in a cookie with a string. Now, when I do so, I recieve a error (Object reference not set to an instance of an object).

So I tried about everything and it still wouldn't work. Why? Someone please help me.

---- Code (Example) ----

Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

If Request.Cookies("cookie1")("item1") = "12345" Then
    Response.Write("It works!")
Else
    Response.Write("At least no error...")
End If


End Sub

cookies are more a pain in the ass than they were in ASP 3.0, but here's some code that might work... i just turned it out in a few mins without testing, but give it a try:

Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 Dim objCookie As System.Web.HttpCookie
 objCookie = HttpContext.Current.Request.Cookies("cookie1")

 Try
     If objCookie.Item("item1").ToString() = "12345" then
          Response.Write("Cookie valid and equal")

     else
          Response.Write("Cookie valid and NOT equal")
     end if
 Catch
     Response.Write("Cookie doesnt exist")
 End Try
End Sub

If I want to Response to a cookie, do I just need to replace the Request with Response?

are you using Visual Studio NET at all?  you'll get the proper syntax for all this stuff through intellisense.. it even gives you "tooltips" on all the different methods and properties
