问题描述

如何创建软件设置日期然后系统无法正常工作和到期日期系统日期无法更改

解决方案

你不能。

无法阻止系统日期或时间被修改：在操作系统加载之前，可以在PC硬件的BIOS设置中更改它。



如果你想要一个牢不可破的限时演示，那么你必须让你的应用程序获得运行许可从网站翼保持时间和许可证的详细信息。



但是不要在此花费太多时间：计算出你将销售多少份副本，计算出由于盗版而无法获得多少销售，并将这与您实施安全性的时间成本进行比较。与没有任何安全措施的情况相比，通过防止盗版来损失更多钱并不需要太多！如果你的方法惹恼了一个合法的用户足以返回产品，那就是用户因为直接和间接的成本而终生丢失。

不，你不能这样做而且它是这不是软件过期的明智之举。

你应该创建一个在试用期后过期的应用程序

how can create Software set the date then system can not work and expiry date then system date can not change

解决方案

You can't.
There is no way to prevent the system date or time being modified: it can be changed in the BIOS settings of the PC hardware before the operating system is even loaded.

If you want an "unbreakable" time limited demo, them you have to have your app "get permission to run" from a website wing maintains the time and licence details.

But don't spend too much time on this: work out how many copies you will sell, work out how many sales you will not get as a result of piracy, and compare that against you time cost to implement security. It doesn't take much for you to lose more money by preventing piracy than you would have done without any security! And if your methods annoy one legitimate user enough to return the product, that's a user lost for life with the direct and indirect costs that involves.

No, You can not do that and it is not a smart way to so software expiration.
You should Create an application that will expire after a trial period
