Problem with accessing cookies?

[lalitha1024]

Hi,
In my Asp.net project when i am login to my site, i'll set th
cookies by using below commands.

Dim IdCookie As New HttpCookie("empid"
ds.Tables(0).Rows(0).Item(0))
Dim FnameCookie As New HttpCookie("empname"
ds.Tables(0).Rows(0).Item(1))
Response.Cookies.Add(IdCookie)
Response.Cookies.Add(FnameCookie)

In each and every page i wrote authorization by using belo
statements.

If Request.Cookies("empid").Value = "" Then
Response.Write("<b> You are not authorised to view thi
page...</b>")
Server.Transfer("employerlogin.aspx")
End If

when i am trying to execute pages separetely in browser i am gettin
below error. i am copying here my total error page.

Where are you setting the following:

Dim IdCookie As New HttpCookie("empid",
ds.Tables(0).Rows(0).Item(0))
Dim FnameCookie As New HttpCookie("empname",
ds.Tables(0).Rows(0).Item(1))
Response.Cookies.Add(IdCookie)
Response.Cookies.Add(FnameCookie)

Is this in Page_Load or is it in Global? It seems on the face of it
you're trying to use a Cookie that doesn't exist. Hence the
NullReference exception. If you could share emphome.aspx.cs that would
be helpful as well.

I was asking you to share the code that sets the cookie. It is likely in
the emphome.aspx.vb file (codebehind). That is where the stack trace
showed the exception.
