C#实现PDA电源/背光管理系统在设置了自动关闭时间会调用这个函数开始记时, 这样我们只要在系统尚未达到关闭时间之前调用他就OK, 通过控制面板查看电源管理中的自动关闭设置发现, 最短关闭时间为一分钟.那么就是说只要我们每59秒调用一次SystemIdleTimerReset即可实现电源永不关闭. -C# Achieve PDA Power/backlight management systems set up the closing time will automatically call this function at the beginning of mind, so long as we have not yet reached in the system before the closing time to call him on OK, through the control panel to view the power management settings of the automatic shut down found that the shortest closing time for one minute. Well, that is to say, as long as we call once every 59 seconds can be realized SystemIdleTimerReset never turn off the power.
