Hi

In ASP.net 4 I am using the code below to try to insert data into an Access table.
What VB code do I use to execute the Insert SQL statement
Protected Sub oInsert()
        '// define a connection to the database
        Dim cs As String = ConfigurationManager.ConnectionStrings("WhatEverNameYouWant").ConnectionString
        cs = cs.Replace("App_Data\GC.accdb", Server.MapPath("App_Data\GC.accdb"))

        Dim cn As New OleDbConnection(cs)


        Dim sFirstName As String
        sFirstName = "Test1"
        Dim sLastName As String
        sLastName = "Test2"
        Dim sEmail As String
        sEmail = "Test3"

        'If sEmail <> "murbro9@yahoo.com" Then
        'Me.TextBox3.Text = "#INVALID EMAIL#"
        'Exit Sub
        'End If

        Dim sSQL As String
        sSQL = "INSERT INTO Test ( [A], [B], [C] ) SELECT '" & sFirstName & "' AS Expr1, '" & sLastName & "' AS Expr2, '" & sEmail & "' AS Expr3"

        '// define the sql statement to execute
        Dim cmd As New OleDbCommand(sSQL, cn)

        Try


            '// open the connection
            cn.Open()

            '// execute the sql statement
            'Using reader As OleDbDataReader = cmd.ExecuteReader(CommandBehavior.CloseConnection)

            ' While reader.Read()
            '// this loops through all of the returned records
            'Response.Write("blah")
            'End While

            'GridView1.DataSource = reader
            'GridView1.DataBind()



            'End Using

        Catch ex As Exception
            Response.Write(ex.Message)

        Finally
            If cn.State <> ConnectionState.Closed Then
                cn.Close()
            End If
        End Try
    End Sub

Well if we're being picky then pratima_mcs' solution will throw an exception because the connection is never opened.
