Where are you setting the following:

Dim IdCookie As New HttpCookie("emp id",
ds.Tables(0).Ro ws(0).Item(0))
Dim FnameCookie As New HttpCookie("emp name",
ds.Tables(0).Ro ws(0).Item(1))
Response.Cookie s.Add(IdCookie)
Response.Cookie s.Add(FnameCook ie)

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.
