Use a masked text box. Just set the mask and it will do the rest for you.

Try doing this (Formats the phone numbers to ###-###-####):

         Private Sub PhoneTextBox_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PhoneTextBox.TextChanged
            If PhoneTextBox.TextLength = 3 Then
                PhoneTextBox.Text = PhoneTextBox.Text + "-"
                'Put the cursor after the last character
                PhoneTextBox.SelectionStart = Len(PhoneTextBox.Text)
            ElseIf PhoneTextBox.TextLength = 7 Then
                PhoneTextBox.Text = PhoneTextBox.Text + "-"
                PhoneTextBox.SelectionStart = Len(PhoneTextBox.Text)
            End If
        End Sub
