Dim a_point As Integer = TextBox1.SelectionStart

Dim bs As String = Regex.Replace(TextBox1.Text, "[^ \d]", "")

If TextBox1.TextLength bs.Length Then

TextBox1.Text = bs

TextBox1.SelectionStart = a_point

End If

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim gs() As String = (From mt As Match In Regex.Matches(TextBox1.Text, "\d*[13579]\b") Select mt.Value).ToArray

TextBox2.Lines = gs

TextBox3.Text = ((From mt As String In gs Select CInt(mt)).ToArray).Sum

End Sub

End Class
