CDC dc;
HBRUSH br;
br.CreateSolidBrush(RGB(255,0,0));
dc.SelectObject(&br);
dc.Rectangle(100,150,200,300);
dc.Ellipse(150,200,300,400);
dc.LineTo(50,100);
dc.MoveTo(100,210);
this->Invalidate();//To call onpaint function

Solution 2

if all you want to do is draw lines and curves, and you have no complex viewing requirements, DirectX is overkill - simply use GDI, or GDI+
 
Create a CPaintDC in your OnPaint method, then use the methods in the base CDC class
