Andrue,
thanks for your quick response.

what I want to do is to get unique id for a specific computer, to protect my
application.

actually I have downloaded some source code to get the disk serial number
but it seems not working.
the code uses two main APIs: CreateFile and DeviceIoControl, and the second
one always return 0 which means error.

the lines below are extract from the codes.

#define IOCTL_STORAGE_QUERY_PROPERTY   CTL_CODE(IOCTL_STORAGE_BASE, 0x0500,
METHOD_BUFFERED, FILE_ANY_ACCESS)

unsigned long GetDiskSerialNumber()
{
      HANDLE hPhysicalDriveIOCTL = 0;

         //  Try to get a handle to PhysicalDrive IOCTL, report failure
         //  and exit if can't.
        char * driveName = "\\\\.\\PhysicalDrive0";

         //  Windows NT, Windows 2000, Windows XP - admin rights not
required
      hPhysicalDriveIOCTL = CreateFile (driveName, 0,
                               FILE_SHARE_READ | FILE_SHARE_WRITE, NULL,
                               OPEN_EXISTING, 0, NULL);

      if (hPhysicalDriveIOCTL != INVALID_HANDLE_VALUE)
      {
         STORAGE_PROPERTY_QUERY query;
         DWORD cbBytesReturned = 0;
         char buffer [10000];

         memset ((void *) & query, 0, sizeof (query));
         query.PropertyId = StorageDeviceProperty;
         query.QueryType = PropertyStandardQuery;

         memset (buffer, 0, sizeof (buffer));

         if ( DeviceIoControl (hPhysicalDriveIOCTL,
IOCTL_STORAGE_QUERY_PROPERTY,
                   & query,
                   sizeof (query),
                   & buffer,
                   sizeof (buffer),
                   & cbBytesReturned, NULL) )
         {
                 STORAGE_DEVICE_DESCRIPTOR * descrip =
(STORAGE_DEVICE_DESCRIPTOR *) & buffer;
                 char serialNumber [1000];

                 strcpy (serialNumber,
                      flipAndCodeBytes ( & buffer [descrip ->
SerialNumberOffset]));
                if (0 == HardDriveSerialNumber [0] &&
                  //  serial number must be alphanumeric
                   //  (but there can be leading spaces on IBM drives)
               (isalnum (serialNumber [0]) || isalnum (serialNumber [19])))
                strcpy (HardDriveSerialNumber, serialNumber);
         }
         else
          {
                DWORD err = GetLastError ();
          }

         memset (buffer, 0, sizeof (buffer));

         CloseHandle (hPhysicalDriveIOCTL);
      }

      ..........
}

any hints are appreciated.
