CClientDC dc(this);
dc.MoveTo(190,209-i);
dc.LineTo(190+a[i],209-i);
如何改变线的颜色啊

[FlyOverSea]

CClientDC dc(this);
CPen m_pen(PS_SOLID,1,RGB(255,0,0));
CPen *p=dc.SelectObject(&m_pen);
dc.MoveTo(0,0);
dc.LineTo(100,100);
dc.SelectObject(p);

SelectObject(yourPen)

[tyjoe]

pen.CreatePen(PS_SOLID , 20, RGB(128,128,128));

printdc.SelectObject(pen);
printdc.SelectStockObject(NULL_BRUSH);//むらしいブラシをセットする
printdc.MoveTo(x,y);
printdc.LineTo(x,y+100);

这样画出来的是一条灰色线~~~~

[allenhai1980]

CClientDC dc(this);
CPen m_pen(笔型，宽度，颜色);
CPen *pOldPen = dc.SelectObject(&m_pen); //necessary
dc.MoveTo(point);
dc.LineTo(point);
dc.SelectObject(pOldPen); //necessary

// 画一条红线如下所示：

COLORREF nColor = RGB(255, 0, 0);
pDC->SetPixelV(m_pntMouseLoc, nColor);
CPen penStroke(PS_SOLID, 1, nColor);
CPen* penPrevious = pDC->SelectObject(&penStroke);
pDC->MoveTo(100, 200);
pDC->LineTo(200, 200);
pDC->SelectObject(penPrevious);
