[Visual Studio文章] 纯VB代码取得硬盘的物理序列号

本站需要登陆后才能查看

      网上有很多获取硬盘序列号的代码,但大部分都只能取得逻辑分区的序列号,而不能取得硬盘的物理序列号。我们知道,逻辑分区的序列号是FORMAT时产生的,重新FORMAT将会改变。这对于要求唯一识别码的程式来说是致命的。这段代码利用API可以取得物理硬盘的很多特性,包括硬盘出厂时的唯一编号。这段代码我是从CSDN论坛获得,原作者不详。我将其稍做修改和增添,独立出两个常用的函数:GetDiskVolume 、GetHardDiskInfo  ......

'============================================
'模块功能:取得硬盘的信息

'调用方法:
'   GetDiskVolume() 取得逻辑盘的序列号
