要这个有什么用？可以生成与硬件相关的注册码。控制软件不重复使用！那么，很多多人认为VB实现不了。自然没有找到方法，一定是实现不了。然而，感谢WWW，我们能在上面找到VC的源码，DELPHI的源码。但是VB的就是见不到。为此，我决定将VC的源码改成VB的，以下即是：

'通常情况下,我们通过=&HEC命令对IDE端口进行监测.获取硬盘信息.
'一般情况下,我们就写个VXD或者DRIVER来完成.但是现在,通过MS的S.M.A.R.T.接口,
'我们可以直接从RING3调用API DeviceIoControl()来获取硬盘信息.下面乃是我的例程:
'另外,也有编译好的版本供大家平时使用.欢迎下载.
