    Default REGEX For Uppercase Alphanumeric

    Hi All,

    I am in need of regex for alphanumeric (uppercase only) values which will verify string of length 5below

    ABCCD - False
    AB12C - True
    ABC12 - True
    12ABC - True
    12345 - False

    If it contain any lowercase then it should result in false as well.

    My regex ^[A-Z0-9]{5}$ is not working for above type of values.

    Thanks
    Raj

    One way to do this would be to split it up into multiple regular expressions: one to make sure it doesn't contain lowercase letters, one to make sure it contains at least one number, and one to check the length.

    I'm not a regular expression wizard, so there might be a way to roll that all up into one, but it didn't immediately occur to me.

    If you're splitting it up into multiple regular expressions, which one is giving you trouble now?
