Override the OnPaint event handler and do it from there, f.ex:

Protected Overrides Sub OnPaint(e As System.Windows.Forms.PaintEventArgs)
    MyBase.OnPaint(e)

    Dim myPen As New Pen(Color.Red, 3) 'to set width of pen

    e.Graphics.DrawEllipse(myPen, 0, 0, _
                           Me.ClientSize.Width - 1, Me.ClientSize.Height - 1)

    myPen.Dispose()

End Sub
