各位大神，请问有哪位知道获取PC的硬盘序列号，谢谢！

以前写的，供参考
引用定义
Private Declare Function GetVolumeInformation Lib "kernel32.dll" Alias "GetVolumeInformationA" (ByVal _
     lpRootPathName As String, ByVal lpVolumeNameBuffer As String, ByVal nVolumeNameSize As Integer, _
     lpVolumeSerialNumber As Long, lpMaximumComponentLength As Long, lpFileSystemFlags As Long, ByVal _
     lpFileSystemNameBuffer As String, ByVal nFileSystemNameSize As Long) As Long '取得内存磁盘参数调用
函数：
Function GetInfoHard(strDrive As String) As Long
     Dim SerialNum As Long, Res As Long, temp1 As String, Temp2 As String
     temp1 = String$(255, Chr$(0)): Temp2 = String$(255, Chr$(0))
     Res = GetVolumeInformation(strDrive, temp1, Len(temp1), SerialNum, 0, 0, Temp2, Len(Temp2))
     GetInfoHard = SerialNum
End Function

调用格式 GetInfoHard("c:\")

不错，学习了
