问题描述

我正在尝试在 Windows 10 上的任务栏按钮上显示进度，但是我在网上找到的两种方法都不起作用.以下示例失败并显示错误 OSError: [WinError -2147312566] Error when loading Typelib/DLL:

I'm trying to show the progress on the taskbar button on Windows 10, but both methods I've found on the Web do not work. The following example fails with the error OSError: [WinError -2147312566] Error when loading Typelib/DLL:

CLSID_TaskbarList = "{56FDF344-FD6D-11d0-958A-006097C9A090}"
IID_ITaskbarList3 = "{EA1AFB91-9E28-4B86-90E9-9E9F8A5EEFAF}"

import comtypes.client as cc

cc.GetModule("TaskbarLib.tlb")

import comtypes.gen.TaskbarLib as tbl
taskbar = cc.CreateObject(CLSID_TaskbarList, interface=tbl.ITaskbarList3)

并且以下示例失败并显示错误 TypeError: 没有注册的接口对象支持此 IID:

and the following example fails with the error TypeError: There is no interface object registered that supports this IID:

import pythoncom

CLSID_TaskbarList = "{56FDF344-FD6D-11d0-958A-006097C9A090}"
IID_ITaskbarList3 = "{EA1AFB91-9E28-4B86-90E9-9E9F8A5EEFAF}"

taskbar = pythoncom.CoCreateInstance(CLSID_TaskbarList, None, pythoncom.CLSCTX_ALL, IID_ITaskbarList3)
print(taskbar)

我做错了什么?
