Title Body

I've written a service for Windows XP+ in python using the With Extended Service Notifications example code. It works great for detecting user logon/logoff lock screen, and other events. The problem is that it never executes shutdown events and gracefully stops the service upon reboot/shutdown. It stays alive through logon/logoff events as well as starting up again after the reboot. Any help would be appreciated. I don't want to use RegisterServiceCtrlHandlerEx and handle console signals if I can help it--services have this functionality built in, I've just mangled it somehow. Here's the code: from os.path import splitext, abspath from sys import modules import win32serviceutil import win32service import win32event import win32api import win32security import win32ts class Service(win32serviceutil.ServiceFramework): _svc_name_ = '_unNamed' _svc_display_name_ = '_Service Template' def __init__(self, *args): win32serviceutil.ServiceFramework.__init__(self, *args) self.log('Initializing Service') self.stop_event = win32event.CreateEvent(None, 0, 0, None) self.server = None def log(self, msg): import servicemanager servicemanager.LogInfoMsg(str(msg)) def logErr(self, msg): import servicemanager servicemanager.LogErrorMsg(str(msg)) def logWarn(self, msg): import servicemanager servicemanager.LogWarningMsg(str(msg)) def sleep(self, sec): win32api.Sleep(sec*1000, True) def GetAcceptedControls(self): # Accept SESSION_CHANGE control rc = win32serviceutil.ServiceFramework.GetAcceptedControls(self) rc |= win32service.SERVICE_ACCEPT_SESSIONCHANGE rc |= win32service.SERVICE_ACCEPT_SHUTDOWN return rc def GetUserInfo(self, sess_id): sessions = win32security.LsaEnumerateLogonSessions()[:-5] for sn in sessions: sn_info = win32security.LsaGetLog
