I am pretty good with perl regular expressions but evidently I am at a loss on why this doesn't work.The code below stores "Person Test" in output variable.
im output As String
Dim userName As String = "Test, Person"
Dim re As New Regex("(w+),s(w+)", RegexOptions.Singleline)
output = re.Replace(userName, "$2 $1")
So why doesn't the following code store "#Test##Person#" in output variable.
Dim output As String
Dim userName As String = "Test, Person"
Dim re As New Regex("(w+),s(w+)")
For Each Match As Match In re.Matches(userName)
output &= "#" & Match.ToString & "#"

In VB.net I've got the following line that removes all non-alphanumeric chars from a string:
return Regex.Replace(build, "[W]", "")
I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:
return Regex.Replace(build, "[W[]_]", "")
However I'm pretty sure that this says
replace non-word or [ or ] or _
how do I negate the tests for the [] and _ chars so that it says
replace non-word and not [ and not ] and not _
Some examples:
"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"
Im trying to work out what the best way to match 2 strings together, but with a difference.
String1 = "dog cat bird chair book table"
String2 = "the dog chassed the cat around the chair"
No I know I can break string1 up by space character and check if each word appears in string 2, I would prefer to not have to do that.If there some sought of regex that would take a group of words and retrun how many of them matched ?
We know that VB string start and end with double quotes " "
So we have to use "" if we want " in VB string.
I wonder if there is a regular expression pattern which will match VB string?.

Basically what I'm trying to achieve is to extract all the words within a piece of string and transfer that from one text box to another text box.
An example piece of the string would be
<laugh:894u8438:4434:words>
However the words within the string will never remain constant and the characters before and after will change. Is there anything that will read the string and take a word from the string without it being pre-programmed. The string it is reading from is uploaded from a text file.
Len gives # of chars in a string in VBScript but I'm trying to find out how to get a # of words, instead.sub fred john_val=window.document.alice.john.value john_len=len(john_val) msgbox "john=" +cstr(john_len) end sub

I was wondering how would i make a search kind of thing, for example if string1 contains all the words in string2 words. like a search(not just if string1 contains string 2).
it should work something like this:

BUT
If string1 is "an apple" and if string2 is "djsjfsfg apple sdfsfssdfs an ashdfjdsgfsdgfj" then string3 would be "djsjfsfg apple sdfsfssdfs an ashdfjdsgfsdgfj"
