区域重绘

 RECT stRect; 

 pThis->m_ceItemInfo.GetWindowRect(&stRect); 

 pThis->m_ceItemInfo.GetParent()->ScreenToClient(&stRect); 

 pThis->m_ceItemInfo.GetParent()->InvalidateRect(&stRect, true); 

判断圆点

 CPoint point;

  GetCursorPos(&point);

  CRect rect;

  GetDlgItem(IDC_EDIT1)->GetWindowRect(&rect);

  if(rect.PtInRect(point))

   return TRUE;
