ctrl + alt + del，ctrl + a，alt + tab [英] ctrl+alt+del, ctrl+a , alt+tab

问题描述

大家好

我创建了一个用于锁定测试环境的浏览器.
我尝试禁用ctrl + a和alt + tab失败.
我不是制作键盘过滤器或将键盘挂在Windows 7中的专家.我确信这是可能的.

当用户尝试使用ctrl + alt + del
时，我试图放置一个消息框(您不允许使用ctrl alt del") 在Windows 7会话下的键盘上(当他在测试环境中使用浏览器时).但我抓不到钥匙.很难.

我关注了这个主题:
按CtrlAltDel；在Win2000/XP的任务列表中隐藏应用程序 [ ^ ]

但似乎在Windows 7下不起作用.

您能帮我创建一个挂钩或键盘过滤器吗?

非常感谢.

hi everyone

I created a browser that locks down an testing environment.
I tried to disable ctrl+a and alt+tab without success.
I m not a specialist for making a keyboard filter or hooking a keyboard in windows 7. I''m sure it''s possible.

I tried to put a messagebox ( "you are not allowed to use ctrl alt del") when a user tried to use the ctrl+alt+del
on the keyboard under a windows 7 session, when he uses the browser with the testing environment. but I can''t catch the keys. it''s hard.

I followed this topic :
Trap CtrlAltDel; Hide Application in Task List on Win2000/XP[^]

but it seems it''s not working under windows 7.

Could you help me to create a hook or a keyboard filter ?

Thanks a lot.

推荐答案

从公认的快速搜索中，似乎唯一的方法是编写自己的msgina.dll版本. >
如果您有更多时间，可能会很幸运地进行搜索，但是我对此表示怀疑.

From an admittedly quick search, it seems that the only way to do that is to write your own version of msgina.dll.

If you have more time you might get lucky with a search, but I doubt it.

很抱歉，如果我收到您不允许使用ctrl + alt + del" ，无论使用哪种软件，这对我永远都不使用该软件都是一个非常令人信服的因素.

严重地，没有功能可能花费那么多.您将使您的用户远离您的产品和公司.帮自己一个忙，一定要避免这种情况，听听我的友好建议.

Sorry to say, if I ever receive "you are not allowed to use ctrl+alt+del", no matter from what piece of software, it will be a very convincing factor for me to never use this software.

Seriously, no feature may cost so much. You will chase your users far away from you product and your company. Do yourself a favor, avoid this thing by all means, listen to my friendly advice.

您无法捕获Ctrl-Alt-Del，并且您当然也无法捕获其从Web浏览器中运行的代码中.

正确的方法是使用组策略并禁用Ctrl-Alt-Del后面的功能.

You cannot trap Ctrl-Alt-Del and you certainly cannot trap it from code running inside a web browser.

The proper way to do this would be to use Group Policy and disable the functions you find behind Ctrl-Alt-Del.
