Reading the Critical Path

VSTO

Following steps are required to accomplish this task:

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

            //Create Application object
            Application projectApplication = new MSProject.Application();

            object missingValue = System.Reflection.Missing.Value;

            //Open an MPP file
            projectApplication.FileOpenEx("Project1.mpp",
                missingValue, missingValue, missingValue, missingValue,
                missingValue, missingValue, missingValue, missingValue,
                missingValue, missingValue, PjPoolOpen.pjPoolReadOnly,
                missingValue, missingValue, missingValue, missingValue,
                missingValue);

            //Create a Project object by assigning active project
            Project project = projectApplication.ActiveProject;

            // Enumerate the tasks
            foreach (Task task in project.Tasks)
            {
                //Get critical tasks
                if (task != null)
                    if ((bool)task.Critical)
                    {
                        Console.WriteLine(task.ID + "  " + task.Name);
                        Console.WriteLine(task.Start);
                        Console.WriteLine(task.Finish + "\n");
                    }
            }

            // Make sure to clean up and close the file
            projectApplication.FileCloseAll(PjSaveType.pjDoNotSave);

###Aspose.Tasks The following steps are required to accomplish this task:

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

            //Open project file
            string fileName = "Project.mpp";
            ProjectReader reader = new ProjectReader();
            Project project = reader.Read(fileName);

            // Get the critical path
            ArrayList criticalPath = new ArrayList(project.GetCriticalPath());

            // Enumerate the tasks in the critical path
            foreach (Aspose.Tasks.Task task in criticalPath)
            {
                Console.WriteLine(task.Id + "  " + task.Name);
                Console.WriteLine(task.Start);
                Console.WriteLine(task.Finish + "\n");
            }
