Python ctypes keybd_event模拟ctrl + alt + delete [英] Python ctypes keybd_event simulate ctrl+alt+delete

问题描述

我正在尝试使用keybd_event模拟ctrl + alt + del，但是它什么也没做，像ctrl + esc或alt + tab这样的东西都可以，但是ctrl + alt + del却不起作用.

I'm trying to simulate ctrl+alt+del with keybd_event but it doesn't do anything, stuff like ctrl+esc or alt+tab do work yet ctrl+alt+del won't work.

import ctypes
ctypes.windll.user32.keybd_event(0x11, 0, 0, 0) #CTRL is down
ctypes.windll.user32.keybd_event(0x12, 0, 0, 0) #ALT is down
ctypes.windll.user32.keybd_event(0x2E, 0, 0, 0) #DEL is down
ctypes.windll.user32.keybd_event(0x2E, 0, 0x0002, 0) #DEL is up
ctypes.windll.user32.keybd_event(0x12, 0, 0x0002, 0) #ALT is up
ctypes.windll.user32.keybd_event(0x11, 0, 0x0002, 0) #CTRL is up

推荐答案

CTRL + ALT + DEL 是一个特殊的键序列，已知作为安全注意序列，出于安全原因，不能使用keybd_input或.

CTRL + ALT + DEL is a special key sequence, known as the secure attention sequence that, for security reasons, cannot be faked using keybd_input or SendInput.

您将需要使用 SendSAS API调用以模拟SAS.请仔细阅读文档，并确保遵守此功能的严格要求.
