Hi all,

Trying to validate a password with a regularexpressionvalidator
But cant get the regex to work correctly
I' look for a Alpha-numeric password of at least 7 in length and no upper
limit in length

Thanks
Robert

I belive that
Regex Passwords = new Regex("\w{7,}");
will do it.
That is:
Any word character (all letters, all numerals)
At least 7 of them.
No upper limit.
Ethan

Haven't tested, but this might start you off :-)

string alphaNum = "[a-zA-Z0-9_]";
string pattern = "";
pattern += alphaNum + alphaNum + alphaNum + alphaNum;
pattern += alphaNum + alphaNum + alphaNum;
pattern += alphaNum + "*";
pattern += "$";

Regards,
Jeroen
