I need a regular expression that validates only letters and numbers
note:letters normal and captalized both

\w+([-+.]\w+)*

that should work.

Hi,That was great dparsons.
now how can I add space to this
letters,numbers plus space allowed

\w+([\s+.]\w+|\s+)*

This will match
a
a[space]
a[space]a
a[space]a[space]
etc

great.
and finally
what about unicode support?if sb writes arabic or farsi or german characters he will get error.
is this also possible to allow these?

That gets to be an extensive expression and I don't have time to sit and write it, looks like your going to have to go to google to finish the pattern. Sorry.
