Android实现远程控制PC(Android[客户端]+Qt[服务器端])

由于本人没有无线路由器，因此用Win7自带的虚拟wifi让手机上网：Win7虚拟wifi

但是，电脑不在我的房间，因此每天晚上在床上玩完手机还要下床去关电脑，让很懒很懒的本人很不爽，因此自己尝试着做了一个远程控制。

软件客户端运行在Android设备上（我的手机是Android的），服务器端运行在我的Win7本本上。客户端用的是Android平台应用编程，服务器端用的是Qt编写的。

首先设置好默认端口，然后设置控制方法，为了方便起见，这里直接利用标准C中的system接口（调用shell，Win7下就是cmd命令提示符了）。客户端发送命令给服务器，服务器直接执行命令，并将标准输出返回给客户端。

下面看一些代码，具体代码可以到这里下载：工程源代码

服务器端：

转动心中的期待，血在澎湃，吃苦流汗算什么。
