I need to validate web data which is by default type string. The fields which are most difficult to validate are DATE type. I have written code over the years to validate such strings but I never felt satisfied that I was thorough. does anyone have any code suggestions for this validation. what I am interested in is strictly a valid date.

9/14/01
09/14/01
09/14/2001
01/14/09
09-14-01
09-14-2001
09.14.01

and on and on

Thanks

Glenn
