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
