regex question

[Smokey Grindle]

I am writing a messaging app (email like) and want to check if a message has
a RE: or FWD: already and if so put a RE[1]: or FWD[1]: type of prefix on it
that increments automatically on each reply to one that has that message
already in it... so the sequence would be like this

Original Message
RE: Original Message
RE[1]: Original Message
RE[2]: Original Message
...... and so on... is there any easy way to do this with a regex or anyone
that has done this before that knows how to? thanks!

Try the following regex

"^RE(\[(?<value>\d+)\])?:.*"

This will match all of the strings you specified. If the Match object contains
a Group called "value", it will contain the number inside the []'s. Example

Dim match As Match = Regex.Match(lin e, "^RE(\[(?<value>\d+)\])?:.*")
If match.Success Then
' It's a RE: line
if match.Groups.Co ntains("value") Then
' It has a []
Dim value As Integer = CInt(match.Grou ps("value").Val ue)
