Adding a New Task in VSTO and Aspose.Tasks

Code Examples

VSTO

To add a task using VSTO:

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

 1//Create an Application object
 2Microsoft.Office.Interop.MSProject.Application projectApplication = new MSProject.Application();
 3object missingValue = System.Reflection.Missing.Value;
 4projectApplication.FileOpenEx("Project2.mpp",
 5    missingValue, missingValue, missingValue, missingValue,
 6    missingValue, missingValue, missingValue, missingValue,
 7    missingValue, missingValue, PjPoolOpen.pjPoolReadOnly,
 8    missingValue, missingValue, missingValue, missingValue,
 9    missingValue);
10Microsoft.Office.Interop.MSProject.Project project = projectApplication.ActiveProject;
11Microsoft.Office.Interop.MSProject.Task task;
12task = project.Tasks.Add("Task1", 1);
13task.Start = "8/23/2012";
14task.Duration = 3 * 8 * 60;
15task.Text1 = "Task1";
16projectApplication.FileCloseAll(Microsoft.Office.Interop.MSProject.PjSaveType.pjSave);

Aspose.Tasks

To add tasks to project files using Aspose.Tasks for .NET:

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

 1ProjectReader reader = new ProjectReader();
 2Project project = reader.Read("Project.mpp");
 3Aspose.Tasks.Task task = new Aspose.Tasks.Task("Task1");
 4task.ActualStart = DateTime.Parse("23-Aug-2012");
 5task.Duration = new TimeSpan(24, 0, 0);
 6task.DurationFormat = TimeUnitType.Day;
 7project.RootTask.Children.Add(task);
 8project.CalcTaskIds();
 9project.CalcTaskUids();
10project.Save("OutputProject.xml", Aspose.Tasks.Saving.SaveFileFormat.XML);
