Title: How To Get A Drive Serial Number
Post by: KingSparta on October 06, 2003, 08:35:50 am

this could be used to make sure this is the same user, or maybe if a user submits data and you use this to make sure the user submits data only once.


Private Declare Function GetVolumeInformation Lib _
"kernel32.dll" Alias "GetVolumeInformationA" (ByVal _
lpRootPathName As String, ByVal lpVolumeNameBuffer As _
String, ByVal nVolumeNameSize As Integer, _
lpVolumeSerialNumber As Long, lpMaximumComponentLength _
As Long, lpFileSystemFlags As Long, ByVal _
lpFileSystemNameBuffer As String, ByVal _
nFileSystemNameSize As Long) As Long
Function GetSerialNumber(strDrive As String) As Long
   Dim SerialNum As Long
   Dim Res As Long
   Dim Temp1 As String
   Dim Temp2 As String
   Temp1 = String$(255, Chr$(0))
   Temp2 = String$(255, Chr$(0))
   Res = GetVolumeInformation(strDrive, Temp1, _
   Len(Temp1), SerialNum, 0, 0, Temp2, Len(Temp2))
   DriveSerialNumber.Text = SerialNum
End Function

Private Sub CmdGetSerialNum_Click()

Call GetSerialNumber("C:\")

End Sub
