操做硬盘序列号计算硬件注册码。

正正在模块中到场以下声明:
Public 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
'得到某一磁盘分区的疑息,如C:

窗体代码以下:
Option Explicit
Private Regid, Localid As Long

Private Sub CmdLocalID_Click()
  '按照C盘序列号得到本ID
  Dim Driver, VolName, Fsys As String
  Dim volNumber, MCM, FSF As Long
  Driver = "c:\"
  Dim res As Long
  res = GetVolumeInformation(Driver, VolName, 127, volNumber, MCM, FSF, Fsys, 127)
  'volNumber是C盘序列号
  Localid = volNumber / 2 + 123456789
  Text1.Text = Localid
End Sub

Private Sub CmdRegID_Click()
  '按照本ID算出注册ID
  If IsNumeric(Text1.Text) Then
    Regid = CLng(Text1.Text) / 4 * 3 + 987654321
  Else
    'error
  End If
  Text2.Text = Regid
End Sub

Private Sub CmndCheckID_Click()
  '考证注册ID
  Dim Driver, VolName, Fsys As String
  Dim volNumber, MCM, FSF As Long
  Driver = "c:\"
  Dim res As Long
  res = GetVolumeInformation(Driver, VolName, 127, volNumber, MCM, FSF, Fsys, 127)
  Dim Tid As Long
  Tid = volNumber / 2 + 123456789
  If Regid = Tid / 4 * 3 + 987654321 Then
    MsgBox "细确!"
  Else
    MsgBox "缺点!"
  End If
End Sub

为便于演示,我正正在窗体上用了两个文本框三个按钮,请按照状况活络操做,能够正正在用户端算出本ID,支给您,您算出注册ID再支给用户,考证固然是正正在用户端啦。ID算法很俭朴,只做树模。此注册ID只能正正在那一台机器上操做,闭于非下足用户去讲是充分啦。
注:如用户格式化C:盘后需重新得到ID。
