Tasks and Calendars

It is possible to associate calendars with particular tasks in Microsoft Project. Aspose.Task supports this functionality.

Tasks with Calendars

The Task class exposes the Calendar property, used to set or get the calendar associated with a task. This property accepts or returns an object of com.aspose.tasks.Calendar class.

To create a calendar for a task in Microsoft Project:

1. Open a project in Microsoft Project.
2. On the Project menu, select Change Working Times, then Create New Calendar.
3. To assign the calendar to a task, double-click the task in the Task Entry form.
4. Select the Advanced tab.

Setting Task Calendar

Create a standard calendar and create a task. Assign the Calendar to the task.

// For complete examples and data files, please go to https://github.com/aspose-tasks/Aspose.Tasks-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(TasksAndCalendars.class);

Project project = new Project();
Task tsk = project.getRootTask().getChildren().add("Task1");
// add a standard calendar
Calendar cal = project.getCalendars().add("TaskCal1");

tsk.set(Tsk.CALENDAR, cal);

Getting Task Calendar

Get a task calendar by traversing the tasks in a project.

// For complete examples and data files, please go to https://github.com/aspose-tasks/Aspose.Tasks-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(TasksAndCalendars.class);

// create a project instance
Project prj = new Project(dataDir + "project5.mpp");

// Declare ChildTasksCollector class object
ChildTasksCollector collector = new ChildTasksCollector();

// Use TaskUtils to get all children tasks in RootTask
TaskUtils.apply(prj.getRootTask(), collector, 0);

// Parse all the recursive children
for (Task tsk : collector.getTasks()) {
    Calendar tskCal = tsk.get(Tsk.CALENDAR);
    System.out.println("Task calendar name:" + tskCal.getName());
}
