Решение
Попробуйте этот код в VB
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
Private Sub Form_Load()
Dim Serial As Long
'Get the volume information
GetVolumeInformation "d:\", vbNullString, 255, Serial, 0, 0, vbNullString, 255
MsgBox Hex(Serial)
End Sub
.
Это должно служить доказательством концепции для вас.Вы можете адаптировать это на ваш язык выбора.

var
Dummy1, Dummy2 : DWord;
begin
