Adding and Removing Calendar Exceptions

Working with Calendar Exceptions

Aspose.Tasks for C++ API helps you manage calendar exceptions. Die Ausnahmen Eigenschaft, die von der Kalenderklasse ausgesetzt ist, die eine Liste von Kalenderception Objekten darstellt und zum Hinzufügen oder Entfernen der Kalenderausnahmen verwendet wird.

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());
    }
}
