其实网上已经有不少现成的软件，它们可以帮你做到一些共享软件的时间控制，比如试用30天，试用100次等。前些天给台湾人写的软件现在需要要一个试用版，由于是繁体，想用网上已有的软件<<幻影加密系统>>来做，但在繁体下一运行就把机子搞死了，害得我新装了繁体2000。后来想想还是自己写算了。-fact, there has been much off-the-shelf software, they can help you do some of the time-sharing software control, such as the 30-day trial, the trial 100 inferior. A few days ago the people of Taiwan to write software now needs to be a trial version, as is traditional, has been to use the Internet software lt; Lt; Mirage encryption system gt; Gt; To do, but in the next run put traditional loom die for, depriving me of the traditional design of 2000.
