睡眠命令后唤醒Windows系统的命令 [英] command to wake up the windows system after sleep command

问题描述

从C＃程序中，我想调用Windows命令提示符，并使系统进入睡眠状态，几秒钟后，我应该唤醒系统。我已成功使系统进入睡眠状态，但几秒钟后无法唤醒它。我试图使其进入睡眠和唤醒状态的命令是 powrprof.dll，SetSuspendState 0,1,0&&超时10&& echo Hello World。

From C# program I want to call windows command prompt and make the system to sleep and after few seconds I should wake the system. I am successful in making the system sleep but I can't wake it up after few seconds. The command that I tried for making it sleep and wake up is "powrprof.dll,SetSuspendState 0,1,0 && timeout 10 && echo "Hello World" ".

链接 http：//www.groovypost。 com / howto / schedule-wake-sleep-windows-automatically / 表示回声将唤醒系统，但无法正常工作。

The link http://www.groovypost.com/howto/schedule-wake-sleep-windows-automatically/ says echo will wake the system but its not working.

推荐答案

可以使用win32 CreateWaitableTimer API。

It is possible using the win32 CreateWaitableTimer API.

• 调用系统睡眠时，创建WaitableTimer的过程必须处于活动状态。


• 示例使用pywin32 api。


• 允许计时器在Windows电源配置中将系统从睡眠状态唤醒。

    from win32event import CreateWaitableTimer
    from win32event import SetWaitableTimer
    from win32event import WaitForSingleObject
    import sys

    def main(minutes):
        minutes = int(minutes)
        handle = CreateWaitableTimer(None, True, 'Wake up')
        dt = -10000000 * minutes * 60 # Convert to seconds.
        SetWaitableTimer(handle, dt, 0, None, None, True)
        rc = WaitForSingleObject(handle, 1000 * (minutes + 1) * 60) # 11 s.
        print ("Done")

    if __name__ == '__main__':
        minutes = sys.argv[1]
        main(minutes)

要从控制台运行上述脚本，请调用wakeupWindows.py，例如：

For running the above script call wakeupWindows.py from console like:

python wakeupWindows.py 2

从现在开始将唤醒定时器设置为2分钟。
脚本将等待2 +1 = 3分钟。
从另一个控制台使用以下命令使系统进入睡眠状态：

Will set the wake up timer to 2 minutes from now. The script will wait for 2 + 1 = 3 minutes. From another console put the system off to sleep using:

shutdown /h

2分钟后，系统将从睡眠中唤醒。

After 2 minutes, the system will wake up from sleep.

类似的实现可以使用C＃或使用pyinstaller将该脚本转换为exe，如这里。

Similar implementations are possible using C# or this script can be converted to an exe using pyinstaller as explained here.
