This seems like a no-brainer but I couldn't find anything on it.

How do I detect if a date variant in Outlook is "empty"? For example TaskItem.DueDate - the duedate is not necessarily filled.

If it's not filled Outlook returns "4501.01.01." - I can test for this value, but this just doesn't seem "elegant" enough.

Thanks!
