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。

以下代码演示如何在设计时设置 RDS.DataControl 参数并将其绑定到数据感知控件。剪切此代码，将此代码粘贴至普通 HTML 文档中的 Body 和 /Body 标记之间，并将其命名为 DataControlDesignVBS.asp<><>。 ASP 脚本将标识服务器。
