自己用vb编写的用软盘给程序加密的小程序

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

Private Sub Form_Load()
   Label1.FontSize = 18
   Label1.Alignment = 2
