pDC->SelectObject(pBrush);

}

If you want to use a different brush, you should create a new one. Here is an example:

void CExoView::OnDraw(CDC* pDC)

{

CExoDoc* pDoc = GetDocument();

ASSERT_VALID(pDoc);

CBrush BrushGreen(RGB(0, 125, 5));

CBrush BrushRed(RGB(255, 2, 5));

CBrush BrushYellow(RGB(250, 255, 5));

CBrush BrushBlue(RGB(0, 2, 255));

CBrush *pBrush;

CPoint Pt[3];

// Top Triangle

Pt[0] = CPoint(125, 10);

Pt[1] = CPoint( 95, 70);

Pt[2] = CPoint(155, 70);

pBrush = pDC->SelectObject(&BrushGreen);

pDC->Polygon(Pt, 3);

// Left Triangle

Pt[0] = CPoint( 80, 80);

Pt[1] = CPoint( 20, 110);

Pt[2] = CPoint( 80, 140);

pBrush = pDC->SelectObject(&BrushRed);

pDC->Polygon(Pt, 3);
