Updating and Removing Calendar

Replacing a Calendar

Calendars are used to see whether resources are available, and when tasks are scheduled. There are different types of calendars. This article looks at how to replace a base calendar, that is, the calendar used for projects and tasks, with another one.

Base calendars come in different forms:

• Standard: the default calendar has a Monday to Friday work week and a day that runs from 08:00 to 17:00.
• 24-hours: used for around the clock working, or for resources that run around the clock.
• Night shift: similar to the standard calendar, the night-shift calendar has a Monday to Saturday morning work week and a day that runs from 23:00 to 08:00.

Replacing a Calendar with a New Calendar

The list of all calendars can be retrieved as CalendarCollection using the Project class. The CalendarCollection can then be used to Remove or Add a new calendar as shown in the following code sample.

The code example given below demonstrates how to replace an existing calendar with a new standard calendar.

// Create project
System::SharedPtr<Project> project = System::MakeObject<Project>(dataDir + u"Project5.mpp");
        
// Access project calendars
System::SharedPtr<CalendarCollection> calColl = project->get_Calendars();
calColl->Remove(calColl->GetByName(u"TestCalendar"));
        
// Add new calendar
System::SharedPtr<Calendar> newCalendar = calColl->Add(u"TestCalendar");
project->Save(dataDir + u"ReplaceCalendar_out.mpp", Aspose::Tasks::Saving::SaveFileFormat::MPP);

Writing Updated Calendar Data to MPP

With Aspose.Tasks for C++, you can update calendar data in a Microsoft Project MPP file and save it back.

The following code shows how to update the calendar data of a project by adding a new calendar and saving it back to the original MPP file. The steps involved in this activity are:

1. Read the source MPP file.
2. Add the calendar data to the project.
3. Save the updated project data back to the MPP file.

System::String resultFile = u"result_WriteUpdatedCalendarDataToMPP_out.mpp";
System::String newFile = u"project_update_test.mpp";
System::String dataDir = Examples::CPP::RunExamples::GetDataDir(System::Reflection::MethodBase::GetCurrentMethod(ASPOSE_CURRENT_FUNCTION)->get_DeclaringType().get_FullName());
    
try
{
    // Create project instance and access calendar
    System::SharedPtr<Project> project = System::MakeObject<Project>(dataDir + newFile);
    System::SharedPtr<Calendar> cal = project->get_Calendars()->GetByUid(3);
    
    // Update the calendar information
    Calendar::MakeStandardCalendar(cal);
    cal->set_Name(u"Test calendar");
    System::SharedPtr<CalendarException> exc = System::MakeObject<CalendarException>();
    exc->set_FromDate(System::DateTime::get_Now());
    exc->set_ToDate(System::DateTime::get_Now().AddDays(2));
    exc->set_DayWorking(true);
    
    System::SharedPtr<WorkingTime> wt1 = System::MakeObject<WorkingTime>();
    wt1->set_FromTime(System::DateTime(10, 1, 1, 9, 0, 0));
    wt1->set_ToTime(System::DateTime(10, 1, 1, 13, 0, 0));
    
    System::SharedPtr<WorkingTime> wt2 = System::MakeObject<WorkingTime>();
    wt2->set_FromTime(System::DateTime(10, 1, 1, 14, 0, 0));
    wt2->set_ToTime(System::DateTime(10, 1, 1, 19, 0, 0));
    
    System::SharedPtr<WorkingTime> wt3 = System::MakeObject<WorkingTime>();
    wt3->set_FromTime(System::DateTime(10, 1, 1, 20, 0, 0));
    wt3->set_ToTime(System::DateTime(10, 1, 1, 21, 0, 0));
    
    exc->get_WorkingTimes()->Add(wt1);
    exc->get_WorkingTimes()->Add(wt2);
    exc->get_WorkingTimes()->Add(wt3);
    cal->get_Exceptions()->Add(exc);
    
    System::SharedPtr<CalendarException> exc2 = System::MakeObject<CalendarException>();
    exc2->set_FromDate(System::DateTime::get_Now().AddDays(7));
    exc2->set_ToDate(exc2->get_FromDate());
    exc2->set_DayWorking(false);
    cal->get_Exceptions()->Add(exc2);
    
    project->Set<System::SharedPtr<Calendar>>(Prj::Calendar(), cal);
    
    // Save project
    project->Save(dataDir + resultFile, Aspose::Tasks::Saving::SaveFileFormat::MPP);
}
catch (System::Exception& ex)
{
    System::Console::WriteLine(ex->get_Message() + u"\nThis example will only work if you apply a valid Aspose License. You can purchase full license or get 30 day temporary license from http:// Www.aspose.com/purchase/default.aspx.");
