MSDE and VDD 2005 conflict?

[Ed Dror]

Hi there,

I'm using VWD 2005 Express and MSDE 2000
after I created a simple guestbook in northwind database with vb code as
follow

Imports System.Data
Imports System.Data.SqlClient
Partial Class Guestbook
Inherits System.Web.UI.Page
Const conString As String =
"Server=myserver;User=myusername;Password=mypassword;Database=Northwind"
Public Function MyInsertMethod() As Integer
Dim con As New SqlConnection(conString)
Dim insertString As String = "INSERT INTO Guests (FirstName,
LastName) VALUES ('" & FirstName.Text & "','" & LastName.Text & " ')"
Dim cmd As New SqlCommand(insertString, con)
con.Open()
cmd.ExecuteNonQuery()
con.Close()
Response.Redirect("Guestslog.aspx")
End Function
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Button1.Click
Call MyInsertMethod()
End Sub

This is the error message that I'm getting (it's work with SQL server 2005
Dev.)

System.Data.SqlClient.SqlException was unhandled by user code
