Private Const MAX_FILENAME_LEN = 256 Public Function DriveSerial(ByVal sDrv As String) As Long
Dim RetVal As Long
Dim str As String * MAX_FILENAME_LEN
Dim str2 As String * MAX_FILENAME_LEN
Dim a As Long
Dim b As Long
GetVolumeInformation sDrv & ":\", str, MAX_FILENAME_LEN, RetVal, _
a, b, str2, MAX_FILENAME_LEN
DriveSerial = RetVal
End Function 功能 返回指定磁盘的序列号 语法 DriveSerial ( sDrv ) 参数 sDrv:字符串，代表盘符 返回值 长整数，序列号 样例 Dim ds As Long
ds = DriveSerial("C")
说明 盘符不必带":\"，如C盘不必填上c:\，而直接用C就行 |
