<DIV>Allard<STRONG>/</STRONG>All...Thanks you very much for help.</DIV>
<DIV> </DIV>
<DIV>Can you please explain the second RegEx as how exactly it rejects string with same characters appears more then 3 times consecutively.</DIV>
<DIV>/[^a-z0-9A-Z@._] |([0-9a-zA-Z])\1{3,}/ </DIV>
<DIV> </DIV>
<DIV>Also I am using online RegEx Validator for ease of use. It can be found at </DIV>
<DIV><A href="http://home.tiscali.be/stevevh/tools/testRE.html">http://home.tiscali.be/stevevh/tools/testRE.html</A></DIV>
<DIV>I tested the regEx /[^a-z0-9A-Z@._] |([0-9a-zA-Z])\1{3,}/ using the tool and it somehow doesn't work.</DIV>
<DIV> </DIV>
<DIV>I figured, I need to spend more time on understanding Quantifiers in RegEx esp curly braces. Is there any URL's or easy to understand tutorial for Quantifiers? or we can collectively develop it together with simple exampls.</DIV>
<DIV> </DIV>
<DIV>Thanks,</DIV>

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>let me have a shot at this... (lets see if i can impress the masters :-)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>For the format validation i believe youŽll need 2 regexps</FONT></DIV>
<DIV><FONT face=Arial size=2>you can use for validation 3 and 4 <FONT face="Times New Roman" size=3>something like : </FONT></FONT></DIV>
<DIV><FONT face=Arial size=2><FONT face="Times New Roman" size=3>/[^a-z0-9A-Z@._] |([0-9a-zA-Z])\1{3,}/ (<-donŽt know if this works :-)</FONT></FONT></DIV>
<DIV><FONT face=Arial size=2><FONT face="Times New Roman" size=3>"if not any of these or repeat a char or number 3 or more times...." then error</FONT></FONT></DIV>
<DIV><FONT face=Arial size=2>and for 2 and 3 </FONT></DIV>
<DIV><FONT face=Arial size=2>/(.*[<FONT face="Times New Roman" size=3>a-zA-Z</FONT>].*[0-<FONT face="Times New Roman" size=3>9</FONT>].*)|(.*[0-<FONT face="Times New Roman" size=3>9</FONT>].*[<FONT face="Times New Roman" size=3>a-zA-Z</FONT>].*)/ two groups to have the situations num char and char num....</FONT></DIV>
<DIV><FONT face=Arial size=2>"If any-no-thing char any-no-thing number any-no-thing OR any-no-thing number any-no-thing char any-no-thing then OK</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>for size you can use /^.{8,24}/ (anything , repeated 8 to 24 times)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Hope this is any help...</FONT></DIV>

<DIV><FONT face=Arial size=2></FONT><FONT face=Arial size=2></FONT><FONT face=Arial size=2></FONT><BR></DIV>
<DIV>Hi </DIV>
<DIV>I have been trying to Develop RegEx for a Password authentication with following rules:</DIV>
<DIV>1) Must be between 8 - 24 characters</DIV>
<DIV>2) Should have atleast 1 digit</DIV>
<DIV>3) Should have atleast 1 Alphabatic Character</DIV>
<DIV>3) Valid characters are [a-z0-9A-Z@._]</DIV>
<DIV>4) Any Characters cannot repeat more then thrice e.g. Password is "mynaaaame1" is </DIV>
<DIV> invalid because character 'a' repeated more then thrice consecutively.</DIV>
<DIV> </DIV>
<DIV>Rule # 1 is taken care of in password textbox by limiting textbox sixe with min=8 and max=24.</DIV>
<DIV> </DIV>
<DIV>Rule # 2 & 3: ^[a-z0-9A-Z@._]+$</DIV>
<DIV> </DIV>
<DIV>Rule # 4: How do I apply it to ^[a-z0-9A-Z@._]+$ RegEx?</DIV>
<DIV> </DIV>
<DIV>Any help/Hints/Direction be much appereciated.</DIV>
<DIV> </DIV>
<DIV>Adios,</DIV>
