ActiveX コントロールやサードパーティのアドオンを使用せずに、VB 6 を使用して HDD ボリュームのシリアル番号を読み取るにはどうすればよいですか?

Private Declare Function GetVolumeInformation _

    (ByVal lpRootPathName As String, _
    ByVal pVolumeNameBuffer 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

Public Function GetSerialNumber( _
    ByVal sDrive As String) As Long

    If Len(sDrive) Then
        If InStr(sDrive, "\\") = 1 Then
            ' Make sure we end in backslash for UNC
            If Right$(sDrive, 1) <> "\" Then
                sDrive = sDrive & "\"
            End If
        Else
            ' If not UNC, take first letter as drive
            sDrive = Left$(sDrive, 1) & ":\"
        End If
    Else
        ' Else just use current drive
        sDrive = vbNullString
    End If

    ' Grab S/N -- Most params can be NULL
    Call GetVolumeInformation( _
        sDrive, vbNullString, 0, GetSerialNumber, _
        ByVal 0&, ByVal 0&, vbNullString, 0)
End Function

呼び出すには:

Dim Drive As String
Drive = InputBox("Enter drive for checking SN")
MsgBox Hex$(GetSerialNumber(Drive))

次のサンプルは、EXE があるドライブのシリアルを提供します。

'APi declaration
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

Sub subHDsn()
Dim TempAPi, VolumeSerial As Long
Dim strPATH As String

    On Error Resume Next

    TempAPi = 0
    VolumeSerial = 0
    If App.Path Like "*:*" Then
        'checking whether the drive is local or mapped
        strPATH = Left(App.Path, 3)
    Else
        'if it's a UNC
        strPATH = Left(App.Path, InStr((InStr(3, App.Path, "\") + 1), App.Path, "\"))
    End If
    'call API
    TempAPi = GetVolumeInformation(strPATH, VolumeName, 100, VolumeSerial, 100, FileSystemFlags, FileSystemName, 100)
    If TempAPi = 0 Then
        MsgBox "Error calling API!", 16
        End
    End If
    'convert from HeX
    HDsn = Hex(VolumeSerial)

End Sub
