以前做了一个小东西，通过手机来控制PPT的翻页，最大化和最小化，东西很简单，近期整理电脑发现了拿来和大家分享一下
主要分为两个部分，客户端和服务器
客户端实现
当初考虑到跨平台的特性就选择了qt来写的，代码很简单，主要是通过socket连接运行在电脑上的server，发送不同的指令完成不同的操作。由于Qt的跨平台性可以将其移植到安卓和iOS上，安卓上使用完全没问题，ios也应该是没问题，我不是土豪，没法用苹果手机测试，有兴趣的大家可以试试

}服务器端
服务器端是Python写的，当然用c++也是可以的，考虑到代码的简洁就选择了python，正好当时刚学了几点的python就用了它，代码写的很烂。服务器的作用主要是调用微软提供的PPT接口完成操作。
