[RESOLVED] Replace characters in RichTextBox?

[tgf-47]

I'm using something like this:

Dim tmp As String = RichTextBox.Text
        tmp = tmp.Replace("[", "{")
        tmp = tmp.Replace(Space(1), "_")

How do I find all the "Enters" and replace them with a "^"?

I have tried vbcrlf and chr(13), but nothing
