title: MFC draw Circle
body: <p>I just started to learn MFC. I need to draw a circle. If I use OnPaint() it works. What should i do that it will draw on background ? Is this the proper function or should I change it?</p>
  
  <pre><code>void Cvaja5Dlg::OnRButtonDown(UINT nFlags, CPoint point)
  {
      CPaintDC dc(this);
      dc.Ellipse(0,0,500,500);
      CDialogEx::OnRButtonDown(nFlags, point);
  }
  </code></pre>
