SMWinservice

by Davide Mastromatteo

Base class to create winservice in Python

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

Instructions:

1. Just create a new class that inherits from this base class

2. Define into the new class the variables

_svc_name_ = "nameOfWinservice"

_svc_display_name_ = "name of the Winservice that will be displayed in scm"

_svc_description_ = "description of the Winservice that will be displayed in scm"

3. Override the three main methods:

def start(self) : if you need to do something at the service initialization.

A good idea is to put here the inizialization of the running condition

def stop(self) : if you need to do something just before the service is stopped.

A good idea is to put here the invalidation of the running condition

def main(self) : your actual run loop. Just create a loop based on your running condition

4. Define the entry point of your module calling the method "parse_command_line" of the new class

5. Enjoy

常见问题

a. 检查Python执行路径是否在PATH变量中。可以在命令行窗口，输入python来确认。

b. 确认 C:\Program Files\Python36\Lib\site-packages\win32\pywintypes36.dll 存在(注意： “36” 是指python安装版本)。如果这个文件不存在，从C:\Program Files\Python36\Lib\site-packages\pywin32_system32\pywintypes36.dll 拷贝到上述目录下。

c. 仍旧存在问题，输入下列命令调试。

python PythonCornerExample.py debug
