We have mentioned that the CDC::MoveTo() method is used to set the starting position
of a line. When using LineTo(), the line would start from the MoveTo() point to the
LineTo() end. As long as you do not call MoveTo(), any subsequent call to LineTo()
would draw a line from the previous LineTo() to the new LineTo() point. You can use
this property of the LineTo() method to draw various lines. Here is an example:void CExoView::OnDraw(CDC* pDC)
{
pDC->MoveTo(60, 20);
pDC->LineTo(60, 122);
pDC->LineTo(264, 122);
pDC->LineTo(60, 20);

Access the OnPaint event of your view class and implement it as follows:
