ExecuteOptions 和 FetchOptions 属性示例 (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。

以下代码演示如何在设计时设置 ExecuteOptions 和 FetchOptions 属性。如果未设置，ExecuteOptions 默认为 adcExecSync。此设置指示调用 RDS.Refresh 方法时，它将在当前调用线程上（即同步）执行。将以下代码剪切并粘贴到记事本或其他文本编辑器中，并将其保存为 ExecuteOptionsDesignVBS.asp。
