DataFactory 对象、Query 方法和 CreateObject 方法示例 (VBScript)

重要

从 Windows 8 和 Windows Server 2012 开始,Windows 操作系统不再包含 RDS 服务器组件(有关更多详细信息,请参阅 Windows 8 和 Windows Server 2012 兼容性实用手册)。 Windows 的未来版本中将移除 RDS 客户端组件。 请避免在新的开发工作中使用该功能,并着手修改当前还在使用该功能的应用程序。 使用 RDS 的应用程序应迁移到 WCF 数据服务

此示例使用 RDS.DataSpace 对象的 CreateObject 方法创建一个 RDSServer.DataFactory 对象。 若要测试此示例,在普通 HTML 文档中的 <Body> 和 </Body> 标记之间剪切和粘贴此代码,并将其命名为 DataFactoryVBS.asp。 ASP 脚本将标识服务器。
