（50points, easy for you)如何画出紧密的细点线？就象TreeView前的细线?

[CCsdnCC]

我在做一个类似于TreeView的控件，想用LineTo之类的简单函数画出紧密的点线，(......如CTreeView item前的细点线)。结果发现不太会用CreatePen的参数来画这种线，谁能来教教我？谢谢关照。(offering 50 points for you).

UINT x;
int position=0;
for(x=0;x<16;x++)
{
CPen pen(PS_SOLID,x*2+1,RGB(0,0,255));
CPen* oldPen=pDC->SelectObject(&pen);

position+=x*2+10;
pDC->MoveTo(20,position);
pDC->LineTo(500,position);

pDC->SelectObject(oldPen);
}

Only this way? I can do this also. I wanna a more elegant way.

CPen pen;
pen.CreatePen(PS_SOLID,9,RGB(0,0,0));
CPen* pOldPen=pDC->SelectObject(&pen);
pDC->MoveTo(10,-100);
pDC->LineTo(100,-100);
pDC->SelectObject(pOldPen);
pen.DeleteObject();

是点线，不是实线。

LinePoint(x1, y1, y2)
{
for(int y = y1; y<y2; y++)
{
moveto(x1, y);
lineto(x1, y+1);
y++;
}
}
要自己控制，没有现成的函数。

LinePoint(x1, y1, y2)
{
for(int y = y1; y<y2; y++)
{
moveto(x1, y);
lineto(x1, y+1);
y++;
}
}

不好意思，我自己解决了,请大家参考：(不过画斜线效果似乎不太好)
-----------------------
LOGBRUSH logBrush;
logBrush.lbStyle = BS_SOLID;
logBrush.lbColor = RGB(0,0,0);

DWORD dwStyle[2];
dwStyle[0]=0;
dwStyle[1]=3;
DWORD * pStyle = (dwStyle);

CPen pen(PS_GEOMETRIC|PS_USERSTYLE,x*2+1, &logBrush, 2, pStyle );
CPen* oldPen=pDC->SelectObject(&pen);

pDC->MoveTo(20, 10);
pDC->LineTo(500, 10);
pDC->LineTo(500, 300);

pDC->SelectObject(oldPen);
pen.DeleteObject();
