How do I get a date from a user, via a form, and then validate their entry,
please?

I currently have textboxes and labels as follows:

........... / ........... / ................
tbDay Lb tbMonth Lb tbYear

where "16/05/2005" would be validated, but
"30/02/2005" (for example) should not be validated........
don't remember 30 days in February anytime recently.

Surely there is an easier way than having to write all the validating code?

Regards.
