    Drawing in a dialog box with MFC

    Hello there

    I want to draw in a dialog box, so I do the following:
    Code:
    void CNewPointDialog::OnPaint() 
    {
    	CPaintDC dc(this); // device context for painting
    	// TODO: Add your message handler code here
    	COLORREF col=0x00ffffff;
    	//CPen pen(
    	CBrush brush(col), *old_brush;
    	CPen pen(PS_SOLID,1,col), *old_pen;
    	old_brush=dc.SelectObject(&brush);
    	old_pen=dc.SelectObject(&pen);
    	dc.Rectangle(83,96,100,106);
    	dc.SelectObject(old_brush);
    }
    but it doesn't work.
    Can you tell me where is my mistake?

    Make sure the set of coordinates you want to paint is valid.

    I'm sure that this coordinates are correct. I even tried:
    Code:
    dc.Rectangle(0,0,3,3);
    and it didn't work again

    The code works fine for me.
    Perhaps the problem lies elsewhere.
    Do you know if your code ever executed?
