I'm usign following code for IDTag extracting where ID->Edit->Text is Edit
field where i show information

# define SHOWERRORANDQUIT Abort();
void __fastcall TMainForm::Mp3IDClick(TObject *Sender)
{
    HANDLE handle;  //handle to the mp3 file
    SECURITY_ATTRIBUTES security_attributes;  //need it to open a file
    HGLOBAL hFileBuffer;  //memory buffer
    DWORD dwBytesRead;  //bytes read
    ID3 tag;  //the ID3 information

    hFileBuffer = GlobalAlloc(GPTR, // object allocation attributes
                              128  // number of bytes to allocate
                             );

    if(!hFileBuffer)
      SHOWERRORANDQUIT;

    //fill in the security struct
    security_attributes.nLength              = sizeof(SECURITY_ATTRIBUTES);
    security_attributes.lpSecurityDescriptor = NULL;
    security_attributes.bInheritHandle       = FALSE;

    handle = CreateFile(FileListBox1->FileName.c_str(),  //the name
                        GENERIC_READ,  //we want to read
                        FILE_SHARE_READ,  //others can read it at the same
time
                        &security_attributes,  //security
                        OPEN_EXISTING,  //the file exists
                        FILE_ATTRIBUTE_NORMAL,  //normal attributes
                        NULL  //no template
                       );
    if(!handle)
      SHOWERRORANDQUIT;

    if(SetFilePointer(handle,  //handle of file
                      -128,  //number of bytes to move file pointer
                      NULL,  //address of high-order word of distance to
move

                     ) == 0xFFFFFFFF)
      {
        CloseHandle(handle);
        SHOWERRORANDQUIT;
      }

    if(!ReadFile(handle,  //handle of file to read
                 GlobalLock(hFileBuffer), //address of buffer that receives
data
                 128,  //number of bytes to read
                 &dwBytesRead,  //address of number of bytes read
                 NULL  //address of structure for data
                ))
      {
        CloseHandle(handle);
        SHOWERRORANDQUIT;
      }
    CloseHandle(handle);

    //did we read 128 bytes?
    if(dwBytesRead != 128)
