循环打开Windows应用程序

Question

我需要一些帮助,以便在最初看起来像一个非常简单的要求.

我必须找到一种在Windows PC上循环打开应用程序的方法,目的是在安装在墙上的大屏幕上一次显示30秒的窗口.通常会有MS Access报告和几个网页.

我最初的想法是,我可以在PC上手动打开这些应用程序,然后运行VBScript来循环它们.但是这有两个问题.

1. 模拟Alt + Tab按键只是切换最近使用的两个应用程序,而不是全部循环使用它们
2. 我无法看到用户能够使用按键逃脱脚本.

任何人都可以建议我如何使用Windows(XP向上)机器上已有的资源实现这一目标？

Answer 1

在WHS中转出VBScript是可行的方法.这似乎有效.
