Hi,

I must write an application that reads a database and create a file mpp.

I manage to create the file and insert Task, but I can not create summary tasks.

C#

String Mission = "";
_AppMSProject = new Microsoft.Office.Interop.MSProject.ApplicationClass();
_AppMSProject.FileOpen(path, false, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Microsoft.Office.Interop.MSProject.PjPoolOpen.pjPoolReadWrite, Missing.Value, Missing.Value, true, Missing.Value);

    _AppMSProject.ActiveProject.DisplayProjectSummaryTask = true;
    int cptTask = _AppMSProject.ActiveProject.Tasks.Count + 1;

    MSProject.Task Tache = null;
    foreach (DataSet.myTableRow row in DataSet.myTable)
    {
        if (Mission != row.Mission)
        {
// Here must be SUMMARY Task
            Mission = row.Mission;
            Tache = _AppMSProject.ActiveProject.Tasks.Add(Mission, cptTask);
                        cptTask++;
            Tache.Manual = false;
        }
        Tache = _AppMSProject.ActiveProject.Tasks.Add(row.Code_type_tache, cptTask);
        Tache.Duration = row.Heures;
        Tache.Type = Microsoft.Office.Interop.MSProject.PjTaskFixedType.pjFixedDuration;
        cptTask++;
    }
    _AppMSProject.FileSaveAs(path, MSProject.PjFileFormat.pjMPP, Missing.Value, false, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, true, Missing.Value);
    _AppMSProject.Visible = true;
}

I tried using :
Tache.SetField(Microsoft.Office.Interop.MSProject.PjField.pjTaskSummary, "Yes");

But it generates an error.

How can I do This.

What is error?

guillaume.digeteca 11-Feb-11 9:28am

The error is : "Invalid argument value"

If I use Tache.GetField(Microsoft.Office.Interop.MSProject.PjField.pjTaskSummary) I obtain the value "No"

I tried several values, but nothing works. I find nothing in the documentation

Hi,

You can use the method _AppMSProject.InsertSummaryTask().

Here is an example:

if(_AppMSProject.InsertSummaryTask())
{
//to change the name
_AppMSProject.ActiveCell.Task.Name = "Task Summary name";

}

This is very buggy though and I still don't understand all of it, but I hope it helps.
