Read Task Timephased Data

In Microsoft Project, timephased data is displayed on the right side of the Task Usage and Resource Usage views. You can write this data manually and programmatically it can be written with Aspose.Tasks for C++ API or get it from a project into your application.

Working with Timephased Data

Aspose.Tasks for C++ API supports reading a task’s time-phased data from Microsoft Project (MPP) files. The time-phased data is retrieved using the Task object’s GetTimephasedData method.

• To retrieve the task work’s time-phased data, the GetTimephasedData method takes the project’s start and finish dates as input parameters.
• To retrieve the task cost’s time-phased data, it takes an additional input parameter that specifies the type of time phase data as TaskCost.

The following piece of code shows how to read a task’s timephased data.

// Create project instance
System::String dataDir = RunExamples::GetDataDir(System::Reflection::MethodBase::GetCurrentMethod(ASPOSE_CURRENT_FUNCTION)->get_DeclaringType().get_FullName());
System::SharedPtr<Project> project1 = System::MakeObject<Project>(dataDir + u"ReadWriteTimephasedData.mpp");
    
// Set project properties
project1->Set(Prj::StartDate(), System::DateTime(2013, 10, 30, 9, 0, 0));
project1->Set<NullableBool>(Prj::NewTasksAreManual(), NullableBool::to_NullableBool(false));
    
// Add task and resources
System::SharedPtr<Task> task = project1->get_RootTask()->get_Children()->Add(u"Task");
System::SharedPtr<Resource> rsc = project1->get_Resources()->Add(u"Rsc");
    
// Set resource rates and task duration
rsc->Set<System::Decimal>(Rsc::StandardRate(), static_cast<System::Decimal>(10));
rsc->Set<System::Decimal>(Rsc::OvertimeRate(), static_cast<System::Decimal>(15));
task->Set<Duration>(Tsk::Duration(), project1->GetDuration(6));
    
// Create resource assignment
System::SharedPtr<ResourceAssignment> assn = project1->get_ResourceAssignments()->Add(task, rsc);
assn->Set(Asn::Stop(), System::DateTime::MinValue);
assn->Set(Asn::Resume(), System::DateTime::MinValue);
    
// Set Backloaded contour, it increases task duration from 6 to 10 days
assn->Set<WorkContourType>(Asn::WorkContour(), Aspose::Tasks::WorkContourType::BackLoaded);
    
project1->SetBaseline(Aspose::Tasks::BaselineType::Baseline);
task->Set<int32_t>(Tsk::PercentComplete(), 50);
    
// Read timephased data
System::SharedPtr<System::Collections::Generic::List<System::SharedPtr<TimephasedData>>> td = assn->GetTimephasedData(assn->Get<System::DateTime>(Asn::Start()), assn->Get<System::DateTime>(Asn::Finish()), Aspose::Tasks::TimephasedDataType::AssignmentRemainingWork)->ToList();
System::Console::WriteLine(td->get_Count());
    
{
    auto timePhasedValue_enumerator = (td)->GetEnumerator();
    decltype(timePhasedValue_enumerator->get_Current()) timePhasedValue;
    while (timePhasedValue_enumerator->MoveNext() && (timePhasedValue = timePhasedValue_enumerator->get_Current(), true))
    {
        System::Console::WriteLine(timePhasedValue->get_Value());
    }
}
