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：中.国.站长站

以下为引用的内容：

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 IfEnd Function Www@@com

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 IfEnd Function 中国站.长站

站.长.站

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。
