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

Question

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);
}

Answer 1

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

Answer 2

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();

Answer 3

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。

Answer 4

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。

Answer 5

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();
