setting and getting cookie

[KnotGoblin]

I am having trouble retreiving a cookie (or setting for that matter).

I am using the following to retreive the cookie on page_load

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    If Not Request.Cookies("pref1") Is Nothing Then
        Trace.Write("cookie value = " & Request.Cookies("pref1").Value)
    Else
        Trace.Write("cookie doesn't exist")
    End If
End Sub

here is the code that sets the cookie.

Private Sub savePref(ByVal pref1 as Integer)
    Dim myCookie As New HttpCookie("pref1")
    myCookie.Value = pref1
    myCookie.Expires = DateTime.MaxValue
    Response.Cookies.Add(myCookie)
End Sub

If i view the cookie in firefox, the cookies has no attributes.
And for IE the cookie never shows up.

Seems you are setting it incorrecly. You set the value with an integer but then try to get it with the name "pref1"

YOu create the name as say "1" with the creation of the cookie then try to get the "pref1" cookie. They are 2 different cookies

i don't know if i agree...when the cookie is declared, it's given the name pref1, the value of the cookie is the integer value of pref1, name should still be pref1, so that may not be the issue...

"...we both know I'm training to become a cagefighter...see what happens if you try 'n hit me..."

Yeah my mistake.. I misread the code..

i am naming the cookie "pref1". (notice the quotes. its a string.)
It just so happens that the variable i am using to assign the the cookie's value is also pref1.

The cookies shows up when i do a trace.

but when i try to put the cookie value in a textbox:

Me.txtPref1.Text = Request.Cookies("pref1").Value

i get:

 [b]Exception Details:[/b] System.NullReferenceException: Object reference not set to an instance of an object.

which i guess is indicating a null value for the cookie.
