I've stripped the error checking from the code below, but it retrieves a
file from an FTP server.

 // Create internet connection.
 HINTERNET h = InternetOpen( _T( "FTPTest" ), INTERNET_OPEN_TYPE_PRECONFIG,
     NULL, NULL, 0 );

 // Connect to FTP server.
 // Set user name and password to NULL to use anonymous login.
 TCHAR *user = _T( "anonymous" );
 TCHAR *password = _T( "none@none.com" );
 HINTERNET c = InternetConnect( h, _T( "172.16.12.1" ),
     INTERNET_DEFAULT_FTP_PORT,
     user, password, INTERNET_SERVICE_FTP, 0, 0 );

 // Remove any existing target file from the file system.
 TCHAR *targetName = _T( "\\nk.bin" );

 if ( !FtpGetFile( c, _T( "nk.bin" ), targetName,
  FALSE, 0, FTP_TRANSFER_TYPE_BINARY, 0 ) )
