通过序列号识别CD-ROM

Question

我对CD识别感兴趣。

我的问题：

是否有可以通过编程方式检索的序列号？

Answer 1

在VB中尝试此代码

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 

这应该作为您的概念证明。您可以根据自己选择的语言进行调整。

从这里采取：VB Forums

Windows.GetVolumeInformation语法

  GetVolumeInformation(
    lpRootPathName: PChar; {the path to the root directory}
    lpVolumeNameBuffer: PChar; {the buffer receiving the volume name}
    nVolumeNameSize: DWORD; {the maximum size of the buffer}
    lpVolumeSerialNumber: PDWORD; {a pointer to the volume serial number}
    var lpMaximumComponentLength: DWORD; {maximum file component name}
    var lpFileSystemFlags: DWORD; {file system flags}
    lpFileSystemNameBuffer: PChar; {the buffer receiving the file system name}
    nFileSystemNameSize: DWORD {the maximum size of the file system name}
  ): BOOL; {returns TRUE or FALSE}

Delphi端口（稍微改编自Andrei G的帖子）

GetCDROMSerial片段：

  function GetCDROMSerial(AVolName: Char ) : DWord;
  var
   Dummy1, Dummy2 : DWord;
  begin
   GetVolumeInformation(
     PChar( AVolName+':' ),
     nil,
     0,
     @Result,
     Dummy1,
     Dummy2,
     nil,
     0
     );
  end;

使用示例：

  ShowMessage(Format('%X', [GetCDROMSerial('F')]));
