I am not familiar with this approach (and I am working on a machine
where I do not have admin privileges), but an alternative is to
download the Windows extensions for Python by Mark Hammond (et. al.) at:<br>
<br>
<a class="moz-txt-link-freetext" href="http://sourceforge.net/projects/pywin32/">http://sourceforge.net/projects/pywin32/</a><br>
<br>
which makes writing a Windows service simple as the following example
illustrates:<br>
<br>
=====================================================<br>
# SmallestService.py<br>
#<br>
# A sample demonstrating the smallest possible service written in
Python.<br>
<br>
import win32serviceutil<br>
import win32service<br>
import win32event<br>
<br>
class SmallestPythonService(win32serviceutil.ServiceFramework):<br>
_svc_name_ = "SmallestPythonService"<br>
_svc_display_name_ = "The smallest possible Python Service"<br>
def __init__(self, args):<br>
win32serviceutil.ServiceFramework.__init__(self, args)<br>
# Create an event which we will use to wait on.<br>
# The "service stop" request will set this event.<br>
self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)<br>
<br>
def SvcStop(self):<br>
# Before we do anything, tell the SCM we are starting the stop
process.<br>
self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)<br>
# And set my event.<br>
win32event.SetEvent(self.hWaitStop)<br>
<br>
def SvcDoRun(self):<br>
# We do nothing other than wait to be stopped!<br>
win32event.WaitForSingleObject(self.hWaitStop,
win32event.INFINITE)<br>
<br>
if __name__=='__main__':<br>
win32serviceutil.HandleCommandLine(SmallestPythonService)<br>
=====================================================<br>
<br>
Just type:<br>
<br>
SmallestService.py -h<br>
<br>
at a shell prompt to see the options for installing/removing etc.<br>
