這兩項磁碟機資料須使用API函數(shù)方可取得，代碼如下：

以下為引用的內(nèi)容：

Private Declare Function GetVolumeInformation Lib "kernel32" Alias "GetVolumeInformationA" (ByVal lpRootPathName As String, ByVal lpVolumeNameBuffer As String, ByVal nVolumeNameSize As Long, lpVolumeSerialNumber As Long, lpMaximumComponentLength As Long, lpFileSystemFlags As Long, ByVal lpFileSystemNameBuffer As String, ByVal nFileSystemNameSize As Long) As Long

Function GetVolumn(X As String) As String
    If Len(X) < 3 Then
        X = Left(X, 1) & ":/"
    Else
        X = Left(X, 3)
    End If
    Dim nRet As Long, VolName As String, VolSN As Long, MaxCompLen As Long
    Dim VolFlags As Long, VolFileSys As String
    VolName = Space$(256)
    VolFileSys = Space$(256)
    nRet = GetVolumeInformation(X, VolName, Len(VolName), _
            VolSN, MaxCompLen, VolFlags, _
            VolFileSys, Len(VolFileSys))
    If nRet = 1 Then
        GetVolumn = VolName
    Else
        GetVolumn = ""
    End If
End Function

Function GetNumber(X As String) As String
    If Len(X) < 3 Then
        X = Left(X, 1) & ":/"
    Else
        X = Left(X, 3)
    End If
    Dim nRet As Long, VolName As String, VolSN As Long, MaxCompLen As Long
    Dim VolFlags As Long, VolFileSys As String
    VolName = Space$(256)
    VolFileSys = Space$(256)
    nRet = GetVolumeInformation(X, VolName, Len(VolName), _
            VolSN, MaxCompLen, VolFlags, _
            VolFileSys, Len(VolFileSys))
    If nRet = 1 Then
        GetNumber = VolSN
    Else
        GetVolumn = ""
    End If
End Function
 

前面的Declare陳述式宣告一個API函數(shù)（GetVolumeInformation），可取得磁碟機的兩項資料。
