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) & ":\"     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陈述式宣告一个API函数（GetVolumeInformation），可取得磁碟机的两项资料。
