This is an example program how to call the SFDB_WKNDate API More details about this example.

Note

The example here references two functions defined in dbm_init.cpp file:

• dbm_example_init
• dbm_example_shutdown

#include <windows.h>
#include <iostream>
#include <string>
 
#include "SFLOG.h"
#include "SFDBM.h"

 bool dbm_example_init(void);
 void dbm_example_shutdown(void);
 
 
int main(){
  // initialize the  logging, licesne and then the calendar module here ..
  if(!dbm_example_init()){
    std::wcout << L" ERROR - Failed to initialize the sdk. Exit!" << std::endl;      
    return -1;
  }

  long dt = 41030; // Tuesday May 1, 2012
  std::wstring szHolidays;
  WORD wkndNo = 1;    // (Saturday, Sunday) wkncode:  0000011
  WORD wkdOption = 1; // (1 = all (default), 2 = ignore holidays, 3 = only short weekends, 4 = only long weekends). 
  WORD direction = 1; // (1 = next weekend(default), 2 = last weekend).
  long lNextWknd = 0;
 
  // Next weekend
  int nRetCode = SFDB_WKNDate(dt, NULL, NULL, 0, wkndNo, wkdOption, direction, &lNextWknd);   //lNextWknd == 41034 (Saturday)
  if(nRetCode == NDK_SUCCESS){
    std::wcout << L" SUCCESS - SFDB_WKNDate for next weekend: " << lNextWknd << std::endl;
 
    // calculate duration of this weekend
    WORD wDur=0;
    nRetCode = SFDB_WKNDur (lNextWknd, NULL, NULL, 0, wkndNo, &wDur);  // wDur == 2
    if(nRetCode == NDK_SUCCESS){
      std::wcout << L" SUCCESS - the duration SFDB_WKNDur for a given weekend: " << wDur << std::endl;

    }
 
  }
  // Previous weekend

    long lPrevWknd = 0;
  nRetCode = SFDB_WKNDate(dt, NULL, NULL, 0, wkndNo, wkdOption, direction, &lPrevWknd);  // lPrevWknd == 41028 (Sunday)
  if(nRetCode == NDK_SUCCESS){
    std::wcout << L" SUCCESS - SFDB_WKNDate for last weekend: " << lPrevWknd << std::endl;              
  }

  // shutdown the calendar, license and logging module here.
