DataFactory 物件、Query 方法和 CreateObject 方法範例 (VBScript)

重要

從 Windows 8 和 Windows Server 2012 開始,Windows 作業系統中不再包含 RDS 伺服器元件 (請參閱 Windows 8 和 Windows Server 2012 相容性操作手冊以取得詳細資訊)。 未來的 Windows 版本將移除 RDS 用戶端元件。 請避免在新的開發工作中使用這項功能,並規劃修改目前使用這項功能的應用程式。 使用 RDS 的應用程式應該移轉至 WCF 資料服務

此範例會使用 RDS.DataSpace 物件的 CreateObject 方法建立 RDSServer.DataFactory 物件。 若要測試此範例,請剪下 <Body> 和 </Body> 標記間的程式碼,貼入一般 HTML 文件並命名為 DataFactoryVBS.asp。 ASP 指令碼會識別您的伺服器。
