Convertion issue on embedded vc++ 4.0

Convertion issue on embedded vc++ 4.0

  You'd need to use MultiByteToWideChar() to convert whatever encoding you're using in your text file to Unicode.

  This is the code that has worked finally! Thanks!

  CString CUtils::GetSerialNumber()
  {

  #ifdef UNICOUSUARIO
  return L"EMULATOR";
  #else
  #ifdef _DEBUG
  return L"EMULATOR";
  #else

  CString m_strCompaqIpaqId, m_strErrorMessage;
  // Start CreateAssetFile.exe
  PROCESS_INFORMATION pi;
  if (!::CreateProcess(TEXT("\\windows\\DeviceID2003.exe"),
  NULL, NULL, NULL, FALSE, 0, NULL, NULL, NULL, &pi)) // DeviceID.exe esta hecho en .NET y deja un archivo DeviceID.TXT con el DeviceID de la PocketPC en el mismo directorio donde se ejecuta.
  {
  /*
  LPVOID lpMsgBuf;
  FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM |
  FORMAT_MESSAGE_IGNORE_INSERTS,NULL,GetLastError(),0, // Default language
  (LPTSTR) &lpMsgBuf,0,NULL);

  // Process any inserts in lpMsgBuf.
  // ...
  // Display the string.
  MessageBox(NULL, (LPCTSTR)"Ahora viene el error", 0, MB_OK | MB_ICONINFORMATION );
  MessageBox(NULL, (LPCTSTR)lpMsgBuf, 0, MB_OK | MB_ICONINFORMATION );
  // Free the buffer.
  LocalFree( lpMsgBuf );
  */
  m_strCompaqIpaqId = _T("");
  m_strErrorMessage += _T("Cannot run \\windows\\DeviceID2003.exe file.");
  return TEXT("CreateProcess");
  }

  // Wait until DeviceID2003.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\\Device_ID.txt"), 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\\Device_ID.txt file.");
  return TEXT("CreateFile");
  }

  // Se lee el Device ID de un archivo txt y luego se traduce entre UNICODE y ANSI
  //get file length
  int dwFileSize = GetFileSize( hInFile, NULL );
  //allocate a buffer for the script file
  char* pszFileBuff = (char*)LocalAlloc( LPTR, dwFileSize );
  if( !pszFileBuff )
  AfxMessageBox( TEXT( "Couldn't Allocate Memory"));

  ReadFile( hInFile,(LPVOID)pszFileBuff,dwFileSize, &dwBytesRead, NULL);
  TCHAR* pszUnicodeBuff = (TCHAR*)LocalAlloc( LPTR,sizeof(TCHAR)*( dwFileSize + 1 ));
  mbstowcs( pszUnicodeBuff, (const char *)pszFileBuff,(size_t)strlen(pszFileBuff) );

  CloseHandle(hInFile);
  
  // CHAR * pszDest = (CHAR*)malloc(256 * sizeof(TCHAR));
  // ConvertTToC(pszDest, pszUnicodeBuff);

  return pszUnicodeBuff;

  #endif // _DEBUG
  #endif // UNICOUSUARIO

  }

  I have resolved it with this

  void CUtils::ConvertTToC(CHAR* pszDest, const TCHAR* pszSrc)
  {
  for(int i = 0; i < _tcslen(pszSrc); i++)
  pszDest = (CHAR) pszSrc;
  }
  
  and the call is this

  CHAR * pszDest = (CHAR*)malloc(256 * sizeof(TCHAR));
  ConvertTToC(pszDest, strSN);

  Now i see characters, not boxes, but i see one character yes and one no, i think it’s because odf the unicode problem. I didn’t find how to use the function you’ve said correctly, do you know what my problem is If it’s again that i need to use that function can you give a quick example of how to use it

  Thanks in advance. Guillermo.
