GetDiskSerial.DLL 是一个标准的Windows动态链接库，它能够让您在你的程序中简单地获取硬盘出厂序列号。理论上讲，硬盘出厂序列号在全球都是唯一的，所以您可以利用此序列号来产生软件的机器码。 GetDiskSerial.DLL 已经成功的应用在各种流行的开发语言，比如Delphi, C++Builder, C#, Visual C++, Visual Basic, Visual Basic.NET, PowerBuilder, Visual Foxpro, Clarion。产品包里已经包含以上开发语言的调用实例。 -GetDiskSerial.DLL is a standard Windows dynamic link library, which allows you to program in your hard drive a simple access to the factory serial number. In theory, the hard disk factory serial number is unique in the world, so you can use this serial number to generate the software machine code. GetDiskSerial.DLL has successfully used in a variety of popular development languages, such as Delphi, C++ Builder, C#, Visual C++, Visual Basic, Visual Basic.NET, PowerBuilder, Visual Foxpro, Clarion. Product package already contains a call to an instance of the above development language.
