自动关机程序
前几天在网上看到一个自动关机的程序，不过是一个共享的，需要花钱，于是我自己就想写一个尝试一下，练练手吧。
说一下前提知识吧：
Windows XP的关机是由Shutdown.exe程序来控制的，位于Windows\System32文件夹中。如
果想让Windows 2000也实现同样的效果，可以把Shutdown.exe复制到系统目录下。
Shutdown.exe的参数，每个都具有特定的用途，执行每一个都会产生不同的效果，比如
“-s”就表示关闭本地计算机，“-a”表示取消关机操作，下面列出了更多参数，大家
可以在Shutdown.exe中按需使用。
-f：强行关闭应用程序
-m \\计算机名：控制远程计算机
-i：显示图形用户界面，但必须是Shutdown的第一个选项
-l：注销当前用户
-r：关机并重启
-t 时间：设置关机倒计时
-c "消息内容"：输入关机对话框中的消息内容（不能超127个字符）
这就是前提知识，其实关机也可以用API（ExitWindowsEx ）函数来实现，但是没有是么心意，也不好玩。我是用SDK编程实现的，所以代码有些“乱”，大家将就着看吧！！！

这个程序其实还有很多的问题，比如时间设计，功能上加强，界面的美观等等，但是也算是有个框架了，大家自己去加把，我就不再弄了。
