Date Validator Regex with format dd-MMM-yyyy, Zero Date

1 New Member
Hi Guys,

This is regular expression for validating dd-MMM-yyyy date format:


It will not allow case like 0-Aug-2007, should be 01-Aug-2007

The date format is dd-MM-yyyy. Maybe if you want to format dates this way you need to include globalization in your validation. HTH.

I'm not sure what the question is but my first reaction was that it would be much easier to parse for human eyes if written as:

^(0?[1-9]|[12][0-9]|3[01])-(jan|feb|mar|ap r|may|jun|jul|a ug|sep|oct|nov| dec)-(19|20)\d\d$

and then made case insensitive by setting RegexOptions.Ig noreCase

(see http://msdn2.microsoft.com/en-us/lib...exoptions.aspx)

Hi all, I am trying to use a regular expression validator to check for the existence of PO Box in an address textbox. The business rule is "No addresses with PO Boxes are allowed." What I want to happen is the Regular Expression Validator to return false only when the string contains PO Box. Currently it is false even when a valid address exists.
