Microsoft Project MPP File Update
With Aspose.Tasks it is possible to update Microsoft Project 2010 MPP files in addition to XML. You can save the updated data to an existing or a new file.
Updating Microsoft Project MPP Files The following examples show how to add a new task to an existing Microsoft Project 2010 file and save it back to the same file. The code goes through the following steps:
- Create an instance of the project reader.
- Read the file.
- Create a task.
- Add the task to the project.
- Re-calculate.
- Save.
The code snippet shows the code first in Java to update the MPP file.
