Get occurrences

The following example shows you how to get all occurrences of a recurring calendar event within a date range.

C++ example

#include <iostream>
#include <vector>
#include <string>
#include <chrono>

#include "independentsoft/graph/graph_client.hpp"
#include "independentsoft/graph/graph_exception.hpp"
#include "independentsoft/graph/util.hpp"
#include "independentsoft/graph/calendars/event.hpp"

using namespace independentsoft::graph;
using namespace independentsoft::graph::calendars;

int main()
{
    try
    {
        GraphClient client;

        client.client_id = "63333333-209e-454e-b7bd-55a4d201270f";
        client.tenant = "independentsoft.onmicrosoft.com";
        client.client_secret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

        std::chrono::system_clock::time_point start = std::chrono::system_clock::now();
        std::chrono::system_clock::time_point end = start + std::chrono::months(3);

        std::vector<Event> occurrences = sync_wait(client.get_occurrences("recurring-event-id-123", start, end));

        for (std::size_t i = 0; i < occurrences.size(); i++)
        {
            std::cout << "Subject = " << occurrences[i].subject << std::endl;
            std::cout << "Start = " << (occurrences[i].start ? Util::to_universal_time(occurrences[i].start->time) : std::string()) << std::endl;
            std::cout << "" << std::endl;
        }
    }
    catch (const GraphException& ex)
    {
        std::cout << "Error: " << ex.code << std::endl;
        std::cout << "Message: " << ex.message << std::endl;
    }

    return 0;
}
