这一章节主要讲解了简单的绘图

主要是通过一些小的例子让我们学会了VC++的一些基本操作

void CDrawView::OnLButtonDown(UINT nFlags, CPoint point) {// TODO: Add your message handler code here and/or call defaultm_ptOrigin = point;//MessageBox("hello");CView::OnLButtonDown(nFlags, point);}void CDrawView::OnLButtonUp(UINT nFlags, CPoint point) {// TODO: Add your message handler code here and/or call default/*//获得窗口的设备描述表HDC hdc;hdc = ::GetDC(m_hWnd);//移动到线条起点MoveToEx(hdc,m_ptOrigin.x,m_ptOrigin.y,NULL);//画线LineTo(hdc,point.x,point.y);//释放::ReleaseDC(m_hWnd,hdc);CView::OnLButtonUp(nFlags, point);*//*//获得窗口的设备描述表对象的指针           CDC* pDC = GetDC();pDC->MoveTo(m_ptOrigin);pDC->LineTo(point);ReleaseDC(pDC);CView::OnLButtonUp(nFlags, point);*//*CClientDC dc(this);dc.MoveTo(m_ptOrigin);dc.LineTo(point);CView::OnLButtonUp(nFlags, point);*//*//CWindowDC wDC(this);//CWindowDC wDC(GetParent());CWindowDC wDC(GetDesktopWindow());wDC.MoveTo(m_ptOrigin);wDC.LineTo(point);CView::OnLButtonUp(nFlags, point);*//* CPen pen(PS_SOLID,1,RGB(255,0,0));CClientDC dc(this);CPen* pOldPen = dc.SelectObject(&pen);dc.MoveTo(m_ptOrigin);dc.LineTo(point);dc.SelectObject(pOldPen);CView::OnLButtonUp(nFlags, point);*//*//定义画刷CBrush brush(RGB(255,0,0));//获得窗口的设备描述表对象CClientDC dc(this);//画矩形dc.FillRect(CRect(m_ptOrigin,point),&brush);CView::OnLButtonUp(nFlags, point);*///创建位图CBitmap bitmap;//加载位图资源bitmap.LoadBitmap(IDB_BITMAP1);//画刷CBrush brush(&bitmap);CClientDC dc(this);dc.FillRect(CRect(m_ptOrigin,point),&brush);CView::OnLButtonUp(nFlags, point);}

后面还有几个小例子就没有一一去写了，基本类似，因为个人觉得实用性不大，需要看相关绘图方面的资料时再回头来看
