RegEx: Replace all BUT line breaks

[polishthug]

Dim reg As System.Text.RegularExpressions.Regex
Me.lblAnswer.Text = System.Text.RegularExpressions.Regex.Replace(lblAnswer.Text, ".", "*")

Okay, so the "." is supposed to convert everything BUT line breaks. Well it converts line breaks as well... how to change so it does not replace line breaks with "*"?

How about this?

Dim txt As String = "blahblah" & Environment.NewLine & "blah blah bleh"
Dim exp As String = "[^\r\n]"
Dim newTxt As String = Regex.Replace(txt, exp, "*")
MessageBox.Show(newTxt)
