How in VB.Net can I extract the value from a string using the RegularExpressions class? For example, say I have the string:[Mon Jan 4 2011] Blah Blah2 Other text and I want to return the "Mon Jan 4 2011" portion in to a variable. I thought you would use the "Regex.Replace" method but I can't seem to figure out how to extract the portion of the string I want.

View 1 RepliesI've been hammering at this over the weekend with no joy - been through page after page of RegEx Language documentation too.It's very easy to negate a match on characters. For example:
Dim MatchString As System.String = "<test0><test0><test1></test1></test0></test0><test0></test0>"
Dim NegationPattern As System.String = "([^<>])"
Dim RepStr As System.String = ""

View 1 RepliesBasically I have a webresponse stream:dim lol as string = readstream.tostring there is a lot of information within the string but only one link starting with http: located near the end of the string - however there is no constant character point where I can start... (i.e. 38)
I want to extract the link from the string i.e. dog cat plane car [URL]..that is approximately how it looks above - words and url substituted I want to just extract [URL]..I had an idea of parsing the string from http: to the end Then after that splitting the string up again to remove the }], however it does not return anything
I was wondering if it was possible to colorize syntax of, say HTML, inside of a RichTextBox by comparing each word in the current line of text against the collection of words in System.Web.RegularExpressions.AspCodeRegex? I'd imagine that from this question it would be possible?

"Info,Reply:Timestamp 75ff, SpecificID c07c343aInfo,Reply:Timestamp 76ff, SpecificID

In the above string, i want to get only BOLD string value.
Sometime the data would be "Info,Reply:Timestamp 75ff, SpecificID c07c343a" and
sometimes it would be many repeated value like
"Info,Reply:Timestamp 75ff, SpecificID c07c343aInfo,Reply:Timestamp 76ff, SpecificID
c07c3089Info,Reply:Timestamp 75ff, SpecificID c07c345aInfo,Reply:Timestamp 76ff, SpecificID
c07c3088..."
Some people say I will be able to get them through regex.
But I don't know how to make regular expression for getting this value.
