Adding and Removing Calendar Exceptions

Working with Calendar Exceptions

Aspose.Tasks for C++ API helps you manage calendar exceptions. The Exceptions property exposed by the Calendar class that represents a List of CalendarException objects and is used to add or remove the calendar exceptions.

The following code example demonstrates how to add, remove and display exceptions.

System::String dataDir = RunExamples::GetDataDir(System::Reflection::MethodBase::GetCurrentMethod(ASPOSE_CURRENT_FUNCTION)->get_DeclaringType().get_FullName());
    
{
    System::SharedPtr<System::IO::FileStream> fs = System::MakeObject<System::IO::FileStream>(dataDir + u"project_test.mpp", System::IO::FileMode::Open);
    // Clearing resources under 'using' statement
    System::Details::DisposeGuard<1> __dispose_guard_0({ fs});
    // ------------------------------------------
    
    try
    {
        // Create project instance
        System::SharedPtr<Project> prj = System::MakeObject<Project>(fs);
        
        // Remove an exception
        System::SharedPtr<Aspose::Tasks::Calendar> cal = prj->get_Calendars()->ToList()->idx_get(0);
        if (cal->get_Exceptions()->get_Count() > 1)
        {
            System::SharedPtr<CalendarException> exc = cal->get_Exceptions()->ToList()->idx_get(0);
            cal->get_Exceptions()->Remove(exc);
        }
        
        // Add an exception
        System::SharedPtr<CalendarException> calExc = System::MakeObject<CalendarException>();
        calExc->set_FromDate(System::DateTime(2009, 1, 1));
        calExc->set_ToDate(System::DateTime(2009, 1, 3));
        cal->get_Exceptions()->Add(calExc);
        
        // Display exceptions
        
        {
            auto calExc1_enumerator = (cal->get_Exceptions())->GetEnumerator();
            decltype(calExc1_enumerator->get_Current()) calExc1;
            while (calExc1_enumerator->MoveNext() && (calExc1 = calExc1_enumerator->get_Current(), true))
            {
                System::Console::WriteLine(System::String(u"From") + calExc1->get_FromDate().ToShortDateString());
                System::Console::WriteLine(System::String(u"To") + calExc1->get_ToDate().ToShortDateString());
            }
        }
    }
    catch(...)
    {
        __dispose_guard_0.SetCurrentException(std::current_exception());
    }
}
