I'm testing out a CMS I've built in ASP.NET and I'm having issues validating a form textarea with a regular expression.
I've used a ReguarExpressionValidator control to make sure a maximum of 4000 characters are entered but have realised I'm not including line breaks in the regular expression and can't figure out how to include them?

I'm trying to write a validator for an ASP.NET txtbox.
How can I validate so the regular expression will only match if the 6th character is a "C" or a "P"?
Here is the kind of text I want to match via a regular Expression
The id="dgSchedule" is always present in the TAG but its location may differ
The table is span over multiple line/contains white spaces/tabs...
I have the regular expression to match the start and end tag respectively over a single line
[Code]....
Is there any regular expression generator available that can generate me a regular expression based on the text I select and the parameters I specify?
can someone tell me the regex pettern to match a string from [a-zA-Z] where each character in the group cannot occur more than n number of times.

I am using regular expressions for matching only digits, minimum 10 digits, maximum 14. I tried:
^[0-9]
I want a regular expression patterns to match for the following example.
USER@DOMAIN.COMDOMAIN\USERUSER
I need only the USER to be extracted from those.
I have a regular expression
^[a-zA-Z+#-.0-9]{1,5}$
which validates that the word contains alpha-numeric characters and few special characters and length should not be more than 5 characters.
How do I make this regular expression to accept a maximum of five words matching the above regular expression.
I'm trying to use a RegularexpressionValidator to match an IP address (with possible wildcards) for an IP filtering system.I'm using the following Regex:
"([0-9]{1,3}\.|\*\.){3}([0-9]{1,3}|\*){1}"
Which works fine when running it in LINQPad with Regex.Matches, but doesn't seem to work when I'm using the validator.Does anyone have a suggestion as to either a better Regex or why it would work in test but not in situ?

When i run a test and i put in my string it matches but it doesn't appear to work in the browser?

View 3 RepliesI've got a text box control on a page and I want people to add URLs, one on each line and then split those URLs into an array.
So, I'm trying to split them on the newline character. I've tried:
.split(Environment.Newline)
.split('vbcrlf')
.split(vbcrlf)
.split((char)Environment.Newline)
I would like to have an regular expression that does not allow any spaces(before,within,after the word) and alphanumeric characters.
View 3 Repliesi have to check if an input string is valid based on the given regular expression.. this is the regular expression.
(a(bb+aaa+((ab)*bb+(aba)*aa)(a+b)*) + (b(aa+bbb+((ba)*aa+(bab)*bb)(a+b)*)
+ is an OR
* is a LOOP, it is optional, it may be done as many as a user wants.
i've tried many ways to solve the problem that my professor gave me but my knowledge isn't that enough to solve this problem..
I'm trying to use the validator to work on a email form to ensure that they enter a valid from email address. That part works. I also want to add to the expression the text that I pre-populate in the txtbox ("Enter your email address") so on postback, after sending the message, I can clear the fields and repopulate that box.
How do I add that wording to the current expression: w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*
