【问题描述】：
我正在尝试使用带有图标和子菜单的 python 添加一些 shell 扩展，但我正在努力比 pywin32 中的演示更进一步。我似乎也无法通过搜索 google 想出任何东西。
我认为我需要注册一个 com 服务器才能根据右键单击的文件/文件夹的位置和文件类型等更改子菜单中的选项。
# A sample context menu handler.
# Adds a 'Hello from Python' menu entry to .py files. When clicked, a
# simple message box is displayed.
#
# To demostrate:
# * Execute this script to register the context menu.
# * Open Windows Explorer, and browse to a directory with a .py file.
# * Right-Click on a .py file - locate and click on 'Hello from Python' on
# the context menu.

您好 GP89。如果您找到解决方案，请返回此处。我正在尝试添加一个仅显示特定文件夹的简单上下文菜单，但我不知道 Win32 编程。
-
嘿，花了很长时间，但我现在差不多了。我在网上找不到任何调试方法或任何示例。我会在接下来的一两天内发布它:)

我把答案放在下面，如果你在注册和取消注册方法中取出文件位，如果你不在你感兴趣的文件夹中，从查询方法中取出
return 0应该能够相当容易地得到你想要的东西
