State (Cookies, sessions etc.)

Here is the code on the form side (Where you enter the data)with all three different methods


Partial Class Default2
Inherits System.Web.UI.Page

Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
' QueryString()
'SessionMethod()
CookieMethod()
End Sub

Protected Sub QueryString()
Response.Redirect("Default3.aspx?Firstname=" & txtFirstName.Text & "&Lastname=" & txtLastName.Text)
End Sub

Protected Sub SessionMethod()
Session("First") = txtFirstName.Text
Session("Last") = txtLastName.Text
Response.Redirect("Default3.aspx")
End Sub

Protected Sub CookieMethod()
Dim chocolateChip As New HttpCookie("sugar")
chocolateChip("first") = txtFirstName.Text
chocolateChip("last") = txtLastName.Text
chocolateChip.Path = "C:\Sugar.txt"
Response.Cookies.Add(chocolateChip)

Response.Redirect("Default3.aspx")
End Sub
End Class

Here is the code from the receiving side:


Partial Class Default3
Inherits System.Web.UI.Page


Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'GetQueryString()
'GetSession()
ReadCookie()
End Sub

Protected Sub GetQueryString()
lblFirstName.Text = Request.QueryString("FirstName")
lblLastName.Text = Request.QueryString("LastName")
End Sub

Protected Sub GetSession()
If Session("First") <> Nothing Then
lblFirstName.Text = Session("First")
lblLastName.Text = Session("Last")
End If
End Sub

Protected Sub ReadCookie()
Dim cookie As HttpCookie = Request.Cookies("C:\sugar.txt")
lblFirstName.Text = cookie("first")
lblLastName.Text = cookie("last")
End Sub
End Class
