As title.
I know how to use Rainlendar_ListAllComponents(), but it can only return all events/tasks or just on a specific day.
If I only want to look no due date tasks, how can I do ?

I can think in getting all components, then filter only those which are task (they begin with "BEGIN:VTODO") and then looking one by one for those which doesn't have "DUE:" in the iCalendar data? (this could be made capturing "DUE:(.-)\n", and if it's null then it doesn't have a due date)
The events in the table can be removed if you need a short table (in stackoverflow.com/questions/12394841/safely-remove-items-from-an-array-table-while-iterating there is a very good way to do this in a O(n) complexity)

Thanks, I will to try.
