单文档画�|�格�Q?br>其实��是�ȝ��的操作�?br>

    CPen mypen,*pCpen;
    mypen.CreatePen(0,0,RGB(0,0,255));
    pCpen=pDC->SelectObject (&mypen);

for(int j=0;j<cy;j+=cy/10)
{  pDC->MoveTo(0,j);
    pDC->LineTo(cx,j);
}
for(int i=0;i<cx;i+=cx/10)
{  pDC->MoveTo(i,0);
    pDC->LineTo(i,cy);
}
pDC->SelectObject (pCpen);
mypen.DeleteObject ();

上面�ȝ��可有可无�Q�若无，则有�pȝ��默认的画�W��?br>�ȝ��的选入选出讑֤�环境�Q�selectobject函数�Q�最后还要删�?br>cx�Q�cy WM_SIZE响应函数里面赋�?br>

void CDrawlineView::OnSize(UINT nType, int cx, int cy)
{
    CView::OnSize(nType, cx, cy);

    // TODO: Add your message handler code here
    this->cx=cx;
    this->cy=cy;

}
