I have posted my code below.
When I use the regex below, along with the text I define in "body", it works when I try it online at http://gskinner.com/RegExr/

VB.net doesnt find any matches though.

can anyone tell me what I need to do so that this regex will work in vb?
Dim body As String = "Customer Information:" & vbNewLine & "Bob Jones" & vbNewLine & "Phone: 442-493-2935"
 
Dim reg3 As New System.Text.RegularExpressions.Regex("(?<=customer information|customer information:)\s*\w*\s\w*", System.Text.RegularExpressions.RegexOptions.IgnoreCase)
        matches = reg.Matches(body)
        If matches.Count > 0 Then
            Dim result As String = matches(0).Value.Trim(" ")
             Return result
        End If

The following returns the matched text. The ^\r at the end will prevent the last carriage return from being picked up. You can use ^\n, but you will get a carriage return character in your match.
(?<=Customer Information:)\s*[^\n]*\n[^\r]*

The above is assuming you have a newline after your phone number in regards to capturing the carriage return.

just wondering if there is any typo:
Dim reg3 As New System.Text.RegularExpressions.Regex("(?<=customer information|customer information:)\s*\w*\s\w*", System.Text.RegularExpressions.RegexOptions.IgnoreCase)
        matches = reg.Matches(body)

You are declaring 'reg3' and then calling 'reg'.Matches
shouldn't that be matches = reg3.Matches(body)
