我想通過使用Python代碼的Windows服務打開/執行另一個程序。當Windows服務啓動時,另一個程序即記事本將被執行。代碼沒有錯誤,但沒有打開程序。代碼如下。通過使用Python的Windows服務打開另一個程序
代碼:
import win32serviceutil
import win32service
import win32event
import win32com.shell.shell as w32shell
import os
import sys
import win32process as process
class SmallestPythonService(win32serviceutil.ServiceFramework):
_svc_name_ = "BSmallestPythonService"
_svc_display_name_ = "BSmallest 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):
win32event.WaitForSingleObject(self.hWaitStop, win32event.INFINITE)
import subprocess
cmd = "notepad.exe"
process = subprocess.Popen(cmd, stdout=subprocess.PIPE, creationflags=0x08000000)
process.wait()
if __name__=='__main__':
win32serviceutil.HandleCommandLine(SmallestPythonService)
在SvcDoRun方法我試過下面的代碼,但沒有成功:
import subprocess
subprocess.Popen('calc.exe', shell=False)
也試過,但沒有成功:
import subprocess
subprocess.call('notepad.exe', shell=False)
也試過但沒有成功:
import win32api
win32api.WinExec('NOTEPAD.exe') # Works seamlessly
我錯過了什麼?或者我以錯誤的方式去做!請幫助
