If I have a regexvalidator in a webform with a validation expression of
^[+]?[0-9]\d* and I put the text 2d in a text box being validated by this
validator, the validator fires.
This regex is a simple one that only allows the user to enter integer
values.
However, if I do this on the server side like this
Regex rx = new Regex(@"^[+]?[0-9]\d*");
Match mt = rx.Match("2d");
I get success!!!! why?? is there an option I should be setting?
5  1081 
I think the regularexpressi onvalidator automatically puts ^ at the start and
$ at the end...2d DOES match ^[+]?[0-9]\d* but it DOES NOT match
^[+]?[0-9]\d*$ (note the extra $ at the end). That's the difference
between the two.
Also, [0-9]\d* can be rewritten as \d+

George,
Glad you got it working. (Good eyes Karl!)
Just a note: You could also use a CompareValidato r instead of the
RegularExpressi onValidator. If you leave the CompareValidato r's
ControlToCompar e property blank and set it's Operator property to
DataTypeCheck you may then set it's Type property to check if a value
entered is a String, Integer, Double, Date, or Currency.
While I love that I can do almost anything with the regular expression
validator I find simple data type checks much easier to set up with the
CompareValidato r.

That is a great tip!!! Thank you much! The regularexpressi onvalidators do
seem like a little overkill for simple type checks

Hi,
I am replaceing a big string using different regular expressions (see
some example at the end of the message). The problem is whenever I
apply a "replace" it makes a new copy of string and I want to avoid
that. My question here is if there is a way to pass either a memory
stream or array of "find", "replace" expressions or any other way to
avoid multiple copies of a string.
Any help will be highly appreciated

I have a regular expression (^(.+)(?=\s*).*\1 ) that results in
matches. I would like to get what the actual regular expression is.
In other words, when I apply ^(.+)(?=\s*).*\1 to " HEART (CONDUCTION
DEFECT) 37.33/2 HEART (CONDUCTION DEFECT) WITH
CATHETER 37.34/2 " the expression is "HEART (CONDUCTION DEFECT)". How
do I gain access to the expression (not the matches) at runtime?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
