我们在编程的时候有时会需要得到系统中逻辑磁盘的一些信息，如磁盘卷标、磁盘序列号、空间大小、剩余空间等，这些信息直接使用VB提供的函数显然是无法得到的。但是，借助于VB对WINDOWS API函数的支持，使用GetVolumeInformation和 GetDiskFreeSpace这两个API函数，我们就可以很容易的得到磁盘的相关信息。-When we programmed the system sometimes needs to be some logical disk information, such as the disk label, disk serial number, space, free space, and so on, the information provided directly a function of VB is obviously impossible to obtain. However, the help of VB to the WINDOWS API function support, the use GetDiskFreeSpace GetVolumeInformation and two API functions, we can easily obtain information on the disk.
