问题解决,改发帖子
程序终于快做完了,现在考虑的是加密问题。请问软件加密中出现的机器码、注册码
是怎样实现的?能提供例子吗或者思路?分不够可以加。另外还有别的好办法吗?

因為程序有問題。
 
不要用定时,还时事件触发吧。
 
我需要监测学生机鼠标、数据等变化情况,如监测对方屏幕变化及教师机对学生机出故障等。只有数组发生变化才传诵数据。平时只传诵几个标志类变量,但是也总出问题。
 
cpu id + 硬盘id = ok
最好加点随机数
 
谢谢!!
cpu id + 硬盘id 又怎么获得。然后在通过计算得到注册码吗?
是存入注册表中校验吗?
 
盘序列号可以得到;

//===================================
调用 SN := GetIdeDiskSerialNumber();
CPU只有Intel的PIII以后系列才有序列号。如果对方的CPU是PII或更老的就不行了,而且还有很多AMD的CPU也没有序列号。
校验吗,我一般是在程序里面!
 
离线数据库里查找一下有很多  ...  找不到我再抄几个来:)  另外 据说加密狗也不错
