VBScript Regex

Hi,

I am looking to get a regex pattern for VBScript that can validate the following

1. A Minimum string must be at least 1 character
2. Maximum length of 15 characters.
3. Must have at lease one alphabetic character (A-Z)
4. Can also accept any of the following characters (0-9) and a hypen (-).

Thanks,

Ward.

(?=.*[A-Z])[A-Z0-9-]{1,15}

If you want to accept small letters too, use

(?=.*[A-Za-z])[A-Za-z0-9-]{1,15}

HTH,
Dan

i'd assume password validation that requires at least one capital letter

(?=.*[A-Z])[A-Za-z0-9-]{1,15}

Unless it's already implied by VBScript's implementation of regexes, you'll also want to put a start and end of string placeholder on your pattern:
^(?=.*[A-Z])[A-Za-z0-9-]{1,15}$

If you don't, the following illegal (and potentially risky) value would be valid, as the A at the end would match:
!@#$%^&*()</input>';drop table students; '%^$^&&*^*&(A
