Detailed explanation of the steps to add an opening method in the right-click menu of an application using Python

Recently, a small tool developed by the project team wanted to add an opening method in the right-click menu. Taking Youdao Cloud Notes as an example, the requirements were disassembled and the code was written

1. Requirements dismantling :

How to manually add a right-click menu to open:

Step1: Open the registry editor, Win +R->Enter "regedit"

##Step2: In HKEY_CLASS ES_ROOT/*/shell (or HKEY_LOCAL_MACHINE/SOFTWARE/Classes/*/shell, the two directories are the same) Add a key: YNote, then create a new item command in this item, and then edit String , add the path of the application, and finally add a space and "%1" after the path and name, and then right-click to find the way to open YNote

2. Code implementation

Method1: implemented through _winreg module:

import _winreg
from _winreg import KEY_ALL_ACCESS 

with _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, r"SOFTWARE\Classes\*\shell") as key:
    print key

    newKey = _winreg.CreateKeyEx(key,"YNote",0,KEY_ALL_ACCESS)
    
    sub_key = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE,r"SOFTWARE\Classes\*\shell\YNote")
    newsubKey = _winreg.CreateKey(sub_key,"command")
    
    _winreg.SetValue(newsubKey,"(Default)",1,"\"C:\Program Files (x86)\Youdao\YoudaoNote\YoudaoNote.exe\" \"%1\"")

Method2: passed win32api and win32con module implementation

import win32api
import win32con

key = win32api.RegOpenKey(win32con.HKEY_LOCAL_MACHINE,r"SOFTWARE\Classes\*\shell")
    
newKey = win32api.RegCreateKey(key,"YNote")
    
sub_key = win32api.RegOpenKey(win32con.HKEY_LOCAL_MACHINE,r"SOFTWARE\Classes\*\shell\YNote")

newsubKey = win32api.RegCreateKey(sub_key,"command")
    
win32api.RegSetValue(newsubKey,"(Default)", win32con.REG_SZ,"\"C:\Program Files (x86)\Youdao\YoudaoNote\YoudaoNote.exe\" \"%1\"")
