使用时,要pDC->SelectObject(),如pDC->SelectObject(font);
CPen://draw line
Pen.CreatePen(PS_SOLID, 2, RGB(250, 0, 0));
pDC->MoveTo(x, y);//origin
pDC->LineTo(x, y);//destination
CBrush://draw shapes
Brush.CreateSolidBrush(RGB(50, 250, 0));
pDC->Rectangle(x1, y1, x2,y2);
CFont://draw characters
font.CreateFont(0, 0, 0, 0, 10/*字体颜色深浅*/, 0, 0, 0, OEM_CHARSET, OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY, DEFAULT_PITCH, _T("楷体"));
