I use the keypress event for this

   Private Sub txtIPS1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtIPS1.KeyPress

        Try
            Select Case e.KeyChar
                Case "0" To "9", ControlChars.Back
                    'do nothing
                Case Else
                    e.Handled = True
            End Select

        Catch ex As Exception
            MsgBox(Err.Description & " M8")
        End Try

    End Sub
