如何编程获得Pocket Pc 2002的机器序列码？

我想获得Pocket Pc 2002机器序列码，因为每台Pocket Pc的序列码都是唯一的，这样就可以控制软件不外流，请问如何用Embedded C++来实现这个需求？我看到有的软件中就有这方面的信息，肯定是可以实现的。

There are two ways to obtain Serial number of a PPC, reading this SN directly from ROM or from data file. Here is the code for reading from file:

CString GetSerialNumber()
{
 // Start CreateAssetFile.exe
 PROCESS_INFORMATION pi;
 if (!::CreateProcess(TEXT("\windows\CreateAssetFile.exe"),
         NULL, NULL, NULL, FALSE, 0, NULL, NULL, NULL, π))
 {
  m_strCompaqIpaqId = _T("");
  m_strErrorMessage += _T("Cannot run \windows\CreateAssetFile.exe file.");
  return TEXT("");
 }
 
 // Wait until CreateAssetFile.exe will be finished
 ::WaitForSingleObject(pi.hProcess, INFINITE);
 
 // Read data from cpqAssetData.dat file
 HANDLE hInFile;
 TCHAR strSN[65];
 DWORD dwBytesRead;  
 hInFile = CreateFile(TEXT("\windows\cpqAssetData.dat"), GENERIC_READ,
           FILE_SHARE_READ, NULL, OPEN_ALWAYS, FILE_ATTRIBUTE_NORMAL, 0);
 
 if (hInFile == INVALID_HANDLE_VALUE) {
  m_strCompaqIpaqId = _T("");
  m_strErrorMessage += _T("Cannot read \windows\cpqAssetData.dat file.");
  return TEXT("");
 }
 
 SetFilePointer(hInFile, 976, NULL, FILE_BEGIN);
 memset(strSN, 0, 64 * sizeof(TCHAR));
 ReadFile(hInFile, &strSN, 64, &dwBytesRead, NULL);
 CloseHandle(hInFile);
 
 return CString(strSN);
}

You can also download iPAQ SDK to read from ROM. Good luck.
