i am trying the example in the wiki for creating tasks and i get an error when opening the file
MPXFile file = new MPXFile();
Aspose.Tasks.Task task1 = file.AddTask();
task1.Name = "Summary Task";
Aspose.Tasks.Task task2 = task1.AddTask();
task2.Name = "First Sub Task";
task2.Duration = new Duration(10, TimeUnit.Days);
task2.Start = new System.DateTime(2003, 1, 1);
Aspose.Tasks.Task task3 = task1.AddTask();
task3.Name = "Second Sub Task";
task3.Duration = new Duration(15, TimeUnit.Days);
then i just output the file to a response filestream as test.mpx to open the file and project gives this error
No calculations can be performed now.
There is a circular relationship in task 3 Summary of Task of "test". The successors of this task refer back to this task or its predecessors, causing a circular reference.
when i continue all 3 tasks are seperate
if i include this code
Aspose.Tasks.Relation rel1 = task3.AddPredecessor(task2);
rel1.Type = TaskLinkType.FinishToStart;
i get this error as well as the previous one
An import error occurred.
Check row 1 column 5.
If you want to link the two tasks, outdent the subtask to a summary task, and then link them.
I am using Project 2003.
