The SFDBM module provide the date and calendar analytics functionality to NumXL SDK. The locality subsystem is used internally by NumXL SDK APIs.

confirgurations

To initialize the licensing subsystem, the client applicatin must passes the license key and the activation code to SFLUC_INIT(.) function.

you'd need ato acquire a license key and generate an activation code foryour machine. This can be accomplished using the sflmgr.exe utility

Upon calling the initialization API (i.e., SFLOG_INIT(.)), the calling application passes the configuration parameters as arguments:

• Basename of the log file.
• Filepath for the logfile on your systems (e.g., c:\temp)
• Log file rotation policies: Maximum filesize, compression and maximum number of files

    nRetCode = SFLUC_INIT( szProdKey.c_str(), szLicenseKey.c_str(),szActivationCode.c_str(), &uLUCToken);
    if(nRetCode == NDK_SUCCESS){
      std::wcout << L" SUCCESS - License system is initialized" << std::endl;
 
      ....
 
 
      // Shutdown the license subsystem and release/free resources
      SFLUC_SHUTDOWN(uLUCToken);
    }
 
    // Flush the log file cache to the disk and close the log file.
    SFLOG_SHUTDOWN(uClientToken);
  }
  exit(0);
}

Note

1. The logging system has two initialization API variants:
   • SFLOG_INITA(.) for single-byte ASCII arguments.
   • SFLOG_INITW(.) for wide character (Unicode) arguments.
2. The helper macro (SFLOG_INIT) expands during compilation to eitehr API variant based on your project Unicode settings.
3. The SFLOG implements a size-based rotation for log files, so when the current log file exceed given limit, the logging system closes the file, rename it, and open a new one file for writing.
4. The number of log (current + older) files reached a given limit, the logging system will delete the oldest file when it open a new file.

Requirements

The SFLUC library is a standalone module, with a runtime dependency on SFLOG.dll.

Target Platform	Windows
Header	SFLUC.h (include Windows.h)
Library	SFLUC.lib
DLL	SFLUC.dll, and SFLOG.dll
