   Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
        Try
            Select Case m.Msg
                Case WM_KEYDOWN
                    Exit Sub
                Case WM_KEYUP
                    Exit Sub
            End Select
            MyBase.WndProc(m)

        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
        MyBase.WndProc(m)
    End Sub

Just for clarification if e = nothing or e.handled is used this line

MyBase.KeyPreview = True

needs added to the form load event.
