Microsoft Project MPP File Update

With Aspose.Tasks for C++ 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 2010 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:

1. Create an instance of the project reader.
2. Read the file.
3. Create a task.
4. Add the task to the project.
5. Re-calculate.
6. Save.

The code example given below demonstrates how to update the MPP file.

Code Samples

// The path to the documents directory.
System::String dataDir = RunExamples::GetDataDir(System::Reflection::MethodBase::GetCurrentMethod(ASPOSE_CURRENT_FUNCTION)->get_DeclaringType().get_FullName());
        
// Read an existing project
System::SharedPtr<Project> project = System::MakeObject<Project>(dataDir + u"MPPFileUpdate.mpp");
        
// Create a new task
System::SharedPtr<Task> task = project->get_RootTask()->get_Children()->Add(u"Task1");
        
task->Set(Tsk::Start(), System::DateTime(2012, 8, 1));
task->Set(Tsk::Finish(), System::DateTime(2012, 8, 5));
        
// Save the project as MPP project file
project->Save(dataDir + u"AfterLinking_out.Mpp", Aspose::Tasks::Saving::SaveFileFormat::MPP);
