Reading the Critical Path in VSTO and Aspose.Tasks

Code Examples

VSTO

Following steps are required to accomplish this task:

Create a new project in Visual Studio.
In the Solution Explorer, right-click and select Add Reference, then select the COM components tab.
Select the Microsoft Project 12.0 Object Library and then click OK.
This imports the Microsoft.Office.Interop.MSProject namespace at the start of the code.Use the code from the following example to read critical tasks.

 1// Create Application object
 2Application projectApplication = new MSProject.Application();
 3object missingValue = System.Reflection.Missing.Value;
 4//Open an MPP file
 5projectApplication.FileOpenEx("Project1.mpp",
 6    missingValue, missingValue, missingValue, missingValue,
 7    missingValue, missingValue, missingValue, missingValue,
 8    missingValue, missingValue, PjPoolOpen.pjPoolReadOnly,
 9    missingValue, missingValue, missingValue, missingValue,
10    missingValue);
11//Create a Project object by assigning active project
12Project project = projectApplication.ActiveProject;
13// Enumerate the tasks
14foreach (Task task in project.Tasks)
15{
16    //Get critical tasks
17    if (task != null)
18        if ((bool)task.Critical)
19        {
20            Console.WriteLine(task.ID + "  " + task.Name);
21            Console.WriteLine(task.Start);
22            Console.WriteLine(task.Finish);
23        }
24}
25// Make sure to clean up and close the file
26projectApplication.FileCloseAll(PjSaveType.pjDoNotSave);

Aspose.Tasks

The following steps are required to accomplish this task:

Create a new project in Visual Studio.
In the Solution Explorer, right-click and select Add Reference, then select the .NET tab.
Select Aspose.Tasks and click OK.
This imports the Aspose.Tasks namespace at the start of the code.
Use the code from the following example to read tasks and resources.

 1string fileName = "Project.mpp";
 2ProjectReader reader = new ProjectReader();
 3Project project = reader.Read(fileName);
 4// Get the critical path
 5ArrayList criticalPath = new ArrayList(project.GetCriticalPath());
 6// Enumerate the tasks in the critical path
 7foreach (Aspose.Tasks.Task task in criticalPath)
 8{
 9  Console.WriteLine(task.Id + "  " + task.Name);
10  Console.WriteLine(task.Start);
11  Console.WriteLine(task.Finish);
12}
