Regex. Reject space

[shapper]

Hello,

I have the following:
^([a-zA-Z0-9]{8,24})$

It accepts only letters and numbers as expected. But it also accepts
spaces. I don't want that.

What am I doing wrong?

Thanks,
Miguel

That pattern looks fine. Post a working snippet of code that demonstrates
the problem. (Something we could paste into a console application and run to
test ourselves.)

There is a free tool: http://www.radsoftware.com.au/regexdesigner/ that I
use for sorting out regular expressions.

I hope this helps,

Are you using this in an asp.net regexvalidator? That validator ignores
empty fields! If you don't want to allow an empty field, add a
RequiredFieldVa lidator.
