Hard Drive Serial number

Does anyone know how can I get the Hard Drive Serial number from a computer?

PLease send me some code examples.
Thanks,
H.

VB Code:

Public Declare Function GetVolumeSerialNumber Lib "kernel32.dll" 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
Public Function VolumeSerialNumber(ByVal RootPath As String) As String
    Dim VolLabel As String
    Dim VolSize As Long
    Dim Serial As Long
    Dim MaxLen As Long
    Dim Flags As Long
    Dim Name As String
    Dim NameSize As Long
    Dim s As String
 
    If GetVolumeSerialNumber(RootPath, VolLabel, VolSize, Serial, MaxLen, Flags, Name, NameSize) Then
        'Create an 8 character string
        s = Format(Hex(Serial), "00000000")
        'Adds the '-' between the first 4 characters and the last 4 characters
        VolumeSerialNumber = Left(s, 4) + "-" + Right(s, 4)
    Else
        'If the call to API function fails the function returns a zero serial number
        VolumeSerialNumber = "0000-0000"
    End If
End Function
 
 
 
To use it do this
GotNum = VolumeSerialNumber("C:\")

I think thats all you need.

Hello: I just thought you may want to know this also.

If I am not mistaken, this will not return a NETWORK drive serial number (Only the local drive).

I think Arc's code is much better, but here is a different way...

Public Function SerialNumber() As Long
Dim fso As Object
Set fso = CreateObject("Scripting.FileSystemObject")
Dim Drive As Object
Set Drive = fso.GetDrive(fso.GetDriveName(fso.GetAbsolutePathName(App.Path)))
SerialNumber = Abs(Drive.SerialNumber)
Set fso = Nothing
Set Drive = Nothing
End Function
