here is the code:

#testservice.py
import win32serviceutil
import win32service
import win32event
import os
import print_time

class testservice(win32serviceutil.ServiceFramework):
_svc_name_ = "service"
_svc_display_name_ = "Pythonservice"

def __init__(self,args):
self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)

def svcStop(self):

---------------------------------------------------
#setup.py
from distutils.core import setup
import py2exe
import sys
sys.argv.append("py2exe")
setup(console=[{"script":'testservice.py'}])

---------------------------------------------------

i dont know which part i been done it wrong & i had look for many resources, but i cant find the answer..

i'm using win xp + pythonwin 2.3

ps: the "print_time.exe" is just a simple script to print current date & time in a txt file. it have been tested & can run correctlly..
