Hi all,
I want a regular expression process such that,
no characters except for the followings will not be allowed.
0-9 a-z A-Z ~ @ # $ % ( ) _ - + =
[ ] { } < ? >
I create a web site with membership. I have a problem. Some body uses
a username GUEST and someother get's the same username (in fact not the
same, but displays as a same username, because,
second username is GUESTx where x replace with the
code ALT+231
so I want to give a sequence of characters to the user, such
that user cannot use except for this crahcters.
I wrote all the characters above...
best regards...
