如何禁用用户在Windows中使用VB.Net更改日期时间？ [英] How can I disable the user to change date time in Windows using VB.Net?

问题描述

我一直在搜索代码以禁用系统中的日期时间更改。但我找不到任何。任何人都可以告诉我它是否可能并告诉我该怎么做？提前谢谢。



我需要将它用于PC管理。用户可能会更改日期和时间，以便他们可以延长使用PC的时间。



我只是想补充说我开发的程序只运行在管理员。那么......该怎么办？



如果用户试图更改日期时间，我如何提出警告？然后保存到数据库？

解决方案

如果您真的想要一个用户无法更改的时钟，请使用时间服务器。 http://en.wikipedia.org/wiki/Time_server [ ^ ]这完全独立于PC时钟，因此不受用户本地操作的影响。

还有更多使用谷歌。

更改系统时间是您无法以任何方式取出的基本用户权利之一，除非您想要使操作系统无法正常运行。如果可以的话，这对用户来说将是严重的犯罪行为。忘了吧。

I have been searching for codes to disable the datetime change in the system. but i cant find any. Can anyone tell me if its possible and tell me how to do it? thanks in advance.

I need to use this for the PC management. The user might change the date and time so that they could extend time in using the PC.

And I just want to add that the program I have developed is running ONLY on admin. so... what to do?

OR HOW CAN I GIVE ALERT IF THE USER HAS TRIED TO CHANGE THE DATE TIME..then save to database ?

解决方案

If you really want a clock that cannot be changed by user then use a time server. http://en.wikipedia.org/wiki/Time_server[^] This is totally independent of PC clock and so is unaffected by anything the user does locally.

Plenty more using google.

Changing time on the system is one of the fundamental user's rights you cannot take out by any means, unless you want to make OS non-functional. If you could, it would be a serious crime against the user. Forget it.

If you want to capture the time change event (why?!), please see: http://www.stevebunting.org/udpd4n6/forensics/timechange.htm[^].
