自己主动检測&后台复制光盘内容

原理：利用python的win32模块，注冊服务，让代码在后台执行，检測光盘并复制文件

启动的方法就是直接在cmd下，main.py install ，然后去windows 的服务下就能够看到The smallestpossible Python Service 这个服务，你能够启动，停止。还能够设置成开机自己主动启动。

启动服务后，会自己主动检測光盘并在后台复制文件

class SmallestPythonService(win32serviceutil.ServiceFramework):

    _svc_name_ = "SmallestPythonService"

    _svc_display_name_ = "The smallest possible Python Service"

    def __init__(self, args):

        win32serviceutil.ServiceFramework.__init__(self, args)

        # Create an event which we will use to wait on.

        # The "service stop" request will set this event.

        self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)

    def SvcStop(self):

        # Before we do anything, tell the SCM we are starting the stop process.

        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)

        # And set my event.

        win32event.SetEvent(self.hWaitStop)

    def SvcDoRun(self):

        #实际执行代码#

        CopyDvd2Hard.copydvd2hard()

        win32event.WaitForSingleObject(self.hWaitStop, win32event.INFINITE)
