Trabajar con duraciones de tareas
Las tareas llevan tiempo, tienen una duración. Las duraciones de tareas realistas ayudan a dar una fecha de finalización realista del proyecto. Aspose.Tasks for C ++ API permite a los desarrolladores establecer duraciones de tareas en proyectos.
Trabajando con duraciones
Las propiedades de duración y formato de duración expuestas por la clase TSK se utilizan para determinar la duración y formato planificados de la duración de una tarea:
- Duración establece y obtiene la duración planificada de una tarea (PIMPAN).
- DurationFormat establece y obtiene formatos definidos por la enumeración de TimeUnType.
Duración en el proyecto Microsoft
Para ver la duración de una tarea en el proyecto de Microsoft, se puede seleccionar más vistas y luego Entrada de tareas desde el menú View.
Configuración de la duración de la tarea usando Aspose.Tasks
El ejemplo del código que se detalla a continuación demuestra cómo aumentar y disminuir la duración de la tarea a 1 semana y media semana respectivamente.
1// Create a new project and add a new task
2System::SharedPtr<Project> project = System::MakeObject<Project>();
3System::SharedPtr<Task> task = project->get_RootTask()->get_Children()->Add(u"Task");
4
5// Task duration in days (default time unit)
6Duration duration = task->Get<Duration>(Tsk::Duration());
7System::Console::WriteLine(u"Duration equals 1 day: {0}", System::ObjectExt::Box<bool>(System::ObjectExt::Equals(System::ObjectExt::ToString(duration), u"1 day")));
8
9// Convert to hours time unit
10duration = duration.Convert(Aspose::Tasks::TimeUnitType::Hour);
11System::Console::WriteLine(u"Duration equals 8 hrs: {0}", System::ObjectExt::Box<bool>(System::ObjectExt::Equals(System::ObjectExt::ToString(duration), u"8 hrs")));
12
13// Get wrapped TimeSpan instance
14System::Console::WriteLine(u"Duration TimeSpan equals to TimeSpan of 8 hrs: {0}", System::ObjectExt::Box<bool>(System::ObjectExt::Equals(duration.get_TimeSpan(), System::TimeSpan::FromHours(8))));
15
16// Increase task duration to 1 week and display if duration is updated successfully
17task->Set<Duration>(Tsk::Duration(), project->GetDuration(1, Aspose::Tasks::TimeUnitType::Week));
18System::Console::WriteLine(u"Duration equals 1 wk: {0}", System::ObjectExt::Box<bool>(System::ObjectExt::Equals(System::ObjectExt::ToString(task->Get<Duration>(Tsk::Duration())), u"1 wk")));
19
20// Decrease task duration and display if duration is updated successfully
21task->Set<Duration>(Tsk::Duration(), task->Get<Duration>(Tsk::Duration()).Subtract(0.5));
22System::Console::WriteLine(u"Duration equals 0.5 wks: {0}", System::ObjectExt::Box<bool>(System::ObjectExt::Equals(System::ObjectExt::ToString(task->Get<Duration>(Tsk::Duration())), u"0.5 wks")));Calculating Durations
It can be useful to calculate the duration of a task in different units such as minutes, hours, etc.
The Tsk class provides the Duration property for accessing task duration, which returns the Duration class object. The Convert method exposed as part of Duration class can then be used to calculate task durations in different units. This method takes TimeUnitType as the input argument and returns the duration as a double value.
The following code example demonstrates how to use this method to retrieve a task’s duration in different units: minute, day, hour, week and month.
1// Create project instance
2System::String dataDir = RunExamples::GetDataDir(System::Reflection::MethodBase::GetCurrentMethod(ASPOSE_CURRENT_FUNCTION)->get_DeclaringType().get_FullName());
3System::SharedPtr<Project> project1 = System::MakeObject<Project>(dataDir + u"TaskDurations.mpp");
4
5// Get a task to calculate its duration in different formats
6System::SharedPtr<Task> task = project1->get_RootTask()->get_Children()->GetById(1);
7
8// Get the duration in Minutes, Days, Hours, Weeks and Months
9double mins = task->Get<Duration>(Tsk::Duration()).Convert(Aspose::Tasks::TimeUnitType::Minute).ToDouble();
10System::Console::WriteLine(u"Duration in Mins: {0}", System::ObjectExt::Box<double>(mins));
11double days = task->Get<Duration>(Tsk::Duration()).Convert(Aspose::Tasks::TimeUnitType::Day).ToDouble();
12System::Console::WriteLine(u"Duration in Days: {0}", System::ObjectExt::Box<double>(days));
13double hours = task->Get<Duration>(Tsk::Duration()).Convert(Aspose::Tasks::TimeUnitType::Hour).ToDouble();
14System::Console::WriteLine(u"Duration in Hours: {0}", System::ObjectExt::Box<double>(hours));
15double weeks = task->Get<Duration>(Tsk::Duration()).Convert(Aspose::Tasks::TimeUnitType::Week).ToDouble();
16System::Console::WriteLine(u"Duration in Weeks: {0}", System::ObjectExt::Box<double>(weeks));
17double months = task->Get<Duration>(Tsk::Duration()).Convert(Aspose::Tasks::TimeUnitType::Month).ToDouble();
18System::Console::WriteLine(u"Duration in Months: {0}", System::ObjectExt::Box<double>(months));
