Calculation Mode in Aspose.Tasks

Introduction

Aspose.Tasks for .NET is a powerful API that allows developers to work with Microsoft Project files programmatically in their .NET applications. One crucial aspect of working with project files is managing calculation modes, which dictate how tasks and project schedules are calculated and updated. In this tutorial, we’ll delve into the various calculation modes supported by Aspose.Tasks for .NET and demonstrate how to use them effectively.

Prerequisites

Before you begin, ensure you have the following:

1. Visual Studio: Make sure you have Visual Studio installed on your system.
2. Aspose.Tasks for .NET: Download and install the Aspose.Tasks for .NET library from here.
3. Basic understanding of C# programming: Familiarize yourself with C# programming concepts.

Applying Automatic Calculation Mode

Step 1: Create a new Project instance

Initialize a new Project object and set its CalculationMode property to CalculationMode.Automatic.

var project = new Project
{
   CalculationMode = CalculationMode.Automatic
};

Step 2: Set project start date and add tasks

Define the start date of the project and add tasks to it.

project.Set(Prj.StartDate, new DateTime(2015, 4, 15));
var task1 = project.RootTask.Children.Add("Task 1");
var task2 = project.RootTask.Children.Add("Task 2");

Step 3: Link tasks

Establish dependencies between tasks.

project.TaskLinks.Add(task1, task2, TaskLinkType.FinishToStart);

Step 4: Verify recalculated dates

Check if the dates have been recalculated automatically.

Console.WriteLine("Task1 Start + 1 Equals Task2 Start : {0} ", task1.Get(Tsk.Start).AddDays(1).Equals(task2.Get(Tsk.Start)));
// Add more verifications as needed

Applying Manual Calculation Mode

Step 1: Create a new Project instance

Initialize a new Project object and set its CalculationMode property to CalculationMode.Manual.

var project = new Project
{
   CalculationMode = CalculationMode.Manual
};

Step 2: Set project start date and add tasks

Define the start date of the project and add tasks to it.

project.Set(Prj.StartDate, new DateTime(2015, 4, 15));
var task1 = project.RootTask.Children.Add("Task 1");
var task2 = project.RootTask.Children.Add("Task 2");

Step 3: Verify task properties

Check if task properties are set correctly in manual mode.

Console.WriteLine("Task1.Id Equals 1 : {0} ", task1.Get(Tsk.Id).Equals(1));
// Add more verifications as needed

Step 4: Link tasks and verify dates

Link tasks together and check if their dates are not recalculated.

project.TaskLinks.Add(task1, task2, TaskLinkType.FinishToStart);

Applying None Calculation Mode

Step 1: Create a new Project instance

Initialize a new Project object and set its CalculationMode property to CalculationMode.None.

var project = new Project
{
   CalculationMode = CalculationMode.None
};

Step 2: Add a new task

Add a new task to the project.

var task = project.RootTask.Children.Add("Task");

Step 3: Verify task properties

Check if task properties are not automatically calculated.

Console.WriteLine("Task.Id Equals 0 : {0} ", task.Get(Tsk.Id).Equals(0));
// Add more verifications as needed

Conclusion

In this tutorial, we’ve explored the calculation modes available in Aspose.Tasks for .NET and learned how to apply them in practical scenarios. Whether you need automatic, manual, or no calculation mode, Aspose.Tasks provides the flexibility to suit your project’s requirements.
