Database hjælpe (C#)
Hej.Jeg har et problem med database.
Jeg ved det er fejlen ved denne kode.
<add name="Northwind" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Test.mdb;" providerName="System.Data.OleDb" />
( Er i web.config )
Men jeg kan ikke finde den.
Hele min kode ser sådan her ud:
<%@ Page Language="VB" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
Protected Sub DataList1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataListItemEventArgs)
Dim s As SqlDataSource = e.Item.FindControl("OrderDetailsDataSource")
s.SelectParameters("OrderID").DefaultValue = e.Item.DataItem("OrderID")
End Sub
</script>
<html xmlns="http://www.w3.org/1999/xhtml">

<br /><br />
<asp:SqlDataSource ConnectionString="<%$ ConnectionStrings:Northwind %>" ID="OrderDetailsDataSource"
runat="server" SelectCommand="SELECT [Order Details].OrderID, Products.ProductName, [Order Details].UnitPrice, [Order Details].Quantity FROM [Order Details] INNER JOIN Products ON [Order Details].ProductID = Products.ProductID WHERE [Order Details].OrderID = @OrderID">
