Retrieving Embedded Documents from a Task's Notes

Tasks in a project file may contain embedded documents as its part such as text files or Word documents. Though, Aspose.Tasks doesn’t support retrieving such documents from a task’s notes property in totality, it can be used in combination with Aspose.Words to retrieve and save such documents. This article shows how this can be achieved using Aspose.Tasks and Aspose.Words.

You will need Aspose.Words for .NET to retrieve the documents using NotesRTF property of a task.

Retrieving Embedded Documents from Task Notes

Project project = new Project("New Project.mpp");
Task task = project.RootTask.Children.GetById(1);

File.WriteAllText("Notes_out.rtf", task.Get(Tsk.NotesRTF));

Document doc = null;
using (MemoryStream stream = new MemoryStream())
using (StreamWriter streamWriter = new StreamWriter(stream))
{
    streamWriter.Write(task.Get(Tsk.NotesRTF));
    doc = new Document(stream);
}

NodeCollection shapes = doc.GetChildNodes(NodeType.Shape, true);
foreach (Aspose.Words.Drawing.Shape shape in shapes)
{
    if (shape.OleFormat != null)
    {
        if (!shape.OleFormat.IsLink)
        {
            // Extract OLE Word object
            if (shape.OleFormat.ProgId == "Word.Document.12")
            {
                MemoryStream stream = new MemoryStream();
                shape.OleFormat.Save(stream);

                Document newDoc = new Document(stream);
                newDoc.Save("RetrieveTaskEmbeddedDocuments_out.doc");
            }
        }
    }
}
