>>>If I were to set the Value propert of a textbox to Date() anything else I try to type in evokes a box saying 'Not a Valid Date'. I have found no way to intercept this message, the only thing I can think of is to ensure all data is converted to String before assigning it, but surely there must be a better way?

It sounds like you will need to create a textbox class to allow this behaviour. You would need to use character date type to prevent the date date datatype from complaining about partial dates. When you get this working you should upload it, sounds useful.
