取得磁碟机之Volumn及SerialNumberaccess教程
(发布时间:2007-6-8 16:25:00 来自:模考网)

适用ACCESS97、2000

 这两项磁碟机资料须使用API函数方可取得,代码如下:
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) & :\
