Hi,
I am not very familiar with writing regular expressions. What I am
trying to do is limit textbox input to two digits, numeric, and if the
entry is less than 10 that it requires a leading zero.
Can someone please help me with this? Links to regular expression
sources and repositories are also appreciated.
Thank you.
John

Hi,
Use this regular expression : "^\d\d$"
where:
^ = begin of string
\d = any digit number 0 to 9
$ = end of string
This will match when string = "01" "03" "20" "99"...
and will not match when string = "1" "123" "2.3"...
Thanks
Jonathan

Hi Jonathan,
Thank you for responding. How does the expression below know the entry
should be two characters in length?
Thank you,
John

Hi,
Use this regular expression : "^\d\d$"
where:
^ =3D begin of string
\d =3D any digit number 0 to 9
$ =3D end of string
This will match when string =3D "01" "03" "20" "99"...
and will not match when string =3D "1" "123" "2.3"...
Thanks

"^\d\d$" mean Start + Digit + Digit + End : Reapeat the \d 2 times
You can also use this expression "^[\d]{2}$" that mean Start + Digit*2 +
End
If you would like to permit one or two digit use this expression:
"^[\d]{1,2}$", {n1,n2} = n1 = min repeating times and n2 max reapeating
times
Hope this will help you
Thanks
