Estimated and Milestone Tasks

In Microsoft Project, milestones are used to monitor a project’s progress. Milestones are crucial points in the project. Typically, a milestone’s a task with no duration but any task can be marked as a milestone. Aspose.Tasks for C++ API helps you manage milestones.

Working with Milestones

The Tsk class exposes the IsEstimated and IsMilestone properties to manage estimated and milestone tasks:

• IsEstimated: set and get whether a task is estimated (bool value).
• IsMilestone: set and get whether a task is a milestone (bool value).

Viewing Estimated and Milestone Tasks in Microsoft Project

To see whether a task is estimates of marked as a milestone in Microsoft Project one can double-click a task in the Task Entry form:

Finding out Whether a Task is Estimated or a Milestone

The following code example demonstrates how to find out whether a task is estimated or a milestone using Aspose.Tasks.

// Read project from file stream
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"EstimatedMilestoneTasks.mpp", System::IO::FileMode::Open);
System::SharedPtr<Project> prj = System::MakeObject<Project>(fs);
fs->Close();
    
// Create a ChildTasksCollector instance
System::SharedPtr<ChildTasksCollector> collector = System::MakeObject<ChildTasksCollector>();
    
// Collect all the tasks from RootTask using TaskUtils
TaskUtils::Apply(prj->get_RootTask(), collector, 0);
    
// Parse through all the collected tasks
    
{
    auto tsk1_enumerator = (collector->get_Tasks())->GetEnumerator();
    decltype(tsk1_enumerator->get_Current()) tsk1;
    while (tsk1_enumerator->MoveNext() && (tsk1 = tsk1_enumerator->get_Current(), true))
    {
        System::String strEst = tsk1->Get<NullableBool>(Tsk::IsEstimated()).get_Value() ? System::String(u"Estimated") : System::String(u"Non-Estimated");
        System::String strMileStone = tsk1->Get<NullableBool>(Tsk::IsMilestone()).get_Value() ? System::String(u"Milestone") : System::String(u"Non-Milestone");
        System::Console::WriteLine(tsk1->Get(Tsk::Name()) + u" : " + strEst);
        System::Console::WriteLine(tsk1->Get(Tsk::Name()) + u" : " + strMileStone);
    }
}
