1. Lines
void CGdiplusDemoView::OnDraw(CDC* pDC)
{
Graphics g(pDC->m_hDC);

g.DrawLine(&pen, 50, 50, 500, 50);
g.DrawRectangle(&pen, 50, 100, 200, 100);
g.DrawEllipse(&pen, 300, 100, 200, 100);
g.DrawPie(&pen, 50, 250, 200, 200, 225, 90);
g.DrawArc(&pen, 300, 250, 200, 200, 225, 90);

2. Polygon and curves
void CGdiplusDemoView::OnDraw(CDC* pDC)
{
Graphics g(pDC->m_hDC);
Pen pen(Color(255, 0, 0, 0), 3);
// Set coordinates
Point points[] = {
Point(30, 30), Point(120, 50), Point(170, 10), Point(150, 90), Point(90, 70), Point(50, 130)
};
// Polygon
g.DrawPolygon(&pen, points, 6);
// Closed curve
for ( int i = 0; i < 6; i++ )
points[i].X += 200;
g.DrawClosedCurve(&pen, points, 6, 0.5f);
// Closed curve
for ( int i = 0; i < 6; i++ )
points[i].X += 200;
g.DrawClosedCurve(&pen, points, 6, 1);
// Opened curve
for ( int i = 0; i < 6; i++ ) {
points[i].X -= 400;
points[i].Y += 150;
}
g.DrawCurve(&pen, points, 6, 0);
// Opened curve
for ( int i = 0; i < 6; i++ )
points[i].X += 200;
g.DrawCurve(&pen, points, 6, 0.5);
// Opend curve
for ( int i = 0; i < 6; i++ )
points[i].X += 200;
g.DrawCurve(&pen, points, 6, 1);
