how i can use visual studio.net 2003 wizard to create that code for me.Thank

If Visual Studio .Net could do all the work, do you think they would need programmers?

To access a Query Variable...

eg http://MyWebserver/MyApp/WebForm1.aspx?Msg=Hello+world

The bold section of that url is called the Query String

you can have multiple variables in here eg.

http://MyWebserver/MyApp/WebForm1.aspx?Var1=Val1&Var2=Val2

This url has two parameters, Var1 and Var2

To get these values you would put this in your code behind....

VB Code:

Option Strict On
Option Explicit On 
 
 
Public Class WebForm1
    Inherits System.Web.UI.Page
 
#Region " Web Form Designer Generated Code "
 
    'This call is required by the Web Form Designer.
    <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
 
    End Sub
 
    'NOTE: The following placeholder declaration is required by the Web Form Designer.
    'Do not delete or move it.
    Private designerPlaceholderDeclaration As System.Object
 
    Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
        'CODEGEN: This method call is required by the Web Form Designer
        'Do not modify it using the code editor.
        InitializeComponent()
    End Sub
 
#End Region
 
    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Put user code to initialize the page here
 
        Dim Var1 As String = Request.QueryString.Item("Var1")
        Dim Var2 As String = Request.QueryString.Item("Var2")
 
        'Check to make sure the variables were set
        If IsNothing(Var1) Then
            'Var1 was not Set
            Var1 = "This Value was Not set!"
        End If
 
        If IsNothing(Var2) Then
            'Var2 was not set
            Var2 = "This Value was Not set!"
        End If
 
        'Display the Variables
 
        Response.Write("The Value of Var1 is: " & Var1 & " <br />") ' <br /> denotes a new line
        Response.Write("The Value of Var2 is: " & Var2 & " <br />")
 
    End Sub
 
End Class
