I would like to be able to extract a number from within a string formatted as follows:
"<[1085674730]> hello foo1, how are you doing?"
I'm a novice with regular expressions, I only want to be able to extract a number that is enclosed in the greater/less-than and bracket symbols, but I'm not sure how to go about it. I have to match numeric digits only, but I'm not sure what syntax is used for only searching within these symbols.
I was wondering why some of the implementations were not working. In fact, the only one that did work was the one described by Matthew Flaschen. But that captures the symbols around the number as well as the number itself. I would like to only capture the number that is encased in the symbols and filter out the symbols themselves.

I have searched on google and asked friends, but have not figured out a way to add dashes while a user is typing either a phone number or a social security number or something of the like. I am using Visual Studio 2008, VB Windows Form. This is not for homework but I enjoy adding things to certain projects and thought this would be neat to incorporate into one of mine. I am also curious about allowing the user to enter the first three numbers for their area code and then send the focus to the next text box so that the user can type the rest of their number. I was thinking I could do something with the text box text entered event procedure where I would send the focus after three characters entered. Not 100% on the entire idea or if there is an easier way.
View 1 RepliesI trying to display in a label the appropriate number of dashes based on the number of letters in a word that the first player entered.
Basically, when you click play, the first person enters a word, then the second player guesses what it is. That person has 2x #ofletters of incorrect tries. I just need to figure out how to get the dashes to display based on # of letters and not a preset one of 5 dashes. The original program accepts only 5-letter word so that line of code is Me.lblWord.Text = "-----". I have modified it so the user can enter any # of chars. I tried making the above line with a lot of dashes so it but the leftover dashes will stay there and the game won't end. Here is what i have right now for my play button:
Private Sub btnPlay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPlay.Click

I have a mini rich text editor on a web page (very similar to the one I am using to post this question) and I want to make use of a double asterisk to indicate which words/phrases should be wrapped in a strong tag.

It is a little like a search and replace, I want to replace any string that contains any substring in parentheses with the same string but the words in parentheses colored RED: Eg

"The Prime Minister (that idiot from Scotland) made a speech today"

Every other <number> is incorrect.

I want to extract a URL value from an INI File as such:
[DEFAULT]
BASEURL=http://www.stackoverflow.com/
[InternetShortcut]
URL=http://www.stackoverflow.com/
So I can get the URL value as the only Match from the Regular expression - but I don't understand enough about them (yet) to do this. I have seen RegEx examples that will parse any INI file and get the Name, Value Pairs I just want to get the URL value only from a file no matter what else it contains. My aim is to have something like this:
Dim _pattern As New Text.RegularExpressions.Regex("RegEx")
Dim _url As String = _pattern.Match(iniContentString).Value
It seems simple but I cannot seem to create a specific case RegEx where I want everything from "URL=" to the vbCrLf at the End to be my "Match". I have refered to Regular-Expressions.info which has been a help before but still cannot get this simple example to work.
have a regular expression in .NET, which will allow only 24 hr time format in the textbox.

I am trying to validate a csv file of domain names (eg. @google.com, @xyz.co.uk, @xyz.edu etc.) I am using the following Regular Expression:
Regex(@"@(?:[a-zA-Z0-9-]+.)+[a-zA-Z]{2,4}$", RegexOptions.Compiled);
Is there scope for improvement on the above?
Regex(@"@(?:[a-zA-Z0-9-]+.)+[a-zA-Z]{2,4}$", RegexOptions.Compiled);
Using the above, I want to pass only values like @gmail.com, @xyz.edu, @co.uk etc...
But I find that the values like abc@gmail.com (valid email ids) also pass through.
