VB版EnumDisk
[free]EnumDisk是一个枚举计算机所有磁盘(包括移动硬盘和U盘)的信息。不过网上只有C的。
花了好几天的时间把C的改成了VB版的。主要的时间花在了重新定义几个关键的Type,因为好多Type直译过来后出现了“水土不服”。主要的原因是有些C中的数据类型长度与VB中的长度不一致,还有一些是MSDN或是网上搜来的C结构定义和实际在调用时的定义也有不一样的,但问题出在哪我也不敢瞎猜。

这个程序可以列出机器中所有磁盘的主要信息:PID、VID、SN、厂商、版本等信息,包括SCSI硬盘的。

但是在调试中也发现了一点问题:比如说ProductIdOffset、VendorIdOffset等数据在有些机器上返回的数据并不是真正的数据所在的偏移地址(数据确时返回了,但就是偏移地址不对)。这个问题在网上也没有搜到相关的信息,原想通过一定的计算来重定位这一类的偏移,但最后调试中发现,在不同的机器上偏移的误差并不一样,只好作罢。这个问题就留给大家自己去找解决方法吧。

下载说明:把下面的代码保存到文本文件,将文件名后缀改成.FRM就可以了。

呵,只是发帖时偶尔看到了有个售价功能,就试了下。
我估计反正想要这个源码的人并不会太多,反正多数初学者就是看了可能也不会有什么兴趣,想看的也不会在乎回个帖的价格。

难道来这里的都以学生居多吗?

都来问作业??

我个人不反对"抄作业",但是在专业课程上,还是靠自己来得实在,因为这是您日后找工作并在相关单位扎

根的一个很重要的指标,说白一就是饭碗,别跟自己过不去,好好努力,很多问题可以不攻自破.
