vs2008和vc6.0

[lionghua]

下面这段代码是从vc6.0转为vs2008后得主要程序。程序的功能很简单，就是孙鑫老师的第十课实现的画图代码

void CDrawView::OnLButtonDown(UINT nFlags, CPoint point) 
{
	// TODO: Add your message handler code here and/or call default
	m_ptOrigin=m_ptOld=point;
	m_bDraw=TRUE;
	CView::OnLButtonDown(nFlags, point);
}

void CDrawView::OnLButtonUp(UINT nFlags, CPoint point) 
{
	// TODO: Add your message handler code here and/or call default
	/*HDC hdc;
	hdc=::GetDC(m_hWnd);
	MoveToEx(hdc,m_ptOrigin.x,m_ptOrigin.y,NULL);
	LineTo(hdc,point.x,point.y);
	::ReleaseDC(m_hWnd,hdc);*/
	/*CDC *pDC=GetDC();
	pDC->MoveTo(m_ptOrigin);
	pDC->LineTo(point);
	ReleaseDC(pDC);*/

	//CClientDC dc(this);
	/*CClientDC dc(GetParent());
	dc.MoveTo(m_ptOrigin);
	dc.LineTo(point);*/

	//CWindowDC dc(this);
	//CWindowDC dc(GetParent());
	/*CWindowDC dc(GetDesktopWindow());
	dc.MoveTo(m_ptOrigin);
	dc.LineTo(point);*/
	/*CPen pen(PS_DOT,1,RGB(0,255,0));
	CClientDC dc(this);
	CPen *pOldPen=dc.SelectObject(&pen);
	dc.MoveTo(m_ptOrigin);
	dc.LineTo(point);
	dc.SelectObject(pOldPen);*/
//	CBrush brush(RGB(255,0,0));

	/*CBitmap bitmap;
	bitmap.LoadBitmap(IDB_BITMAP1);
	CBrush brush(&bitmap);*/
	/*CClientDC dc(this);
	//dc.FillRect(CRect(m_ptOrigin,point),&brush);
	CBrush *pBrush=CBrush::FromHandle((HBRUSH)GetStockObject(NULL_BRUSH));
	CBrush *pOldBrush=dc.SelectObject(pBrush);
	dc.Rectangle(CRect(m_ptOrigin,point));
	dc.SelectObject(pOldBrush);*/
	m_bDraw=FALSE;
	CView::OnLButtonUp(nFlags, point);
}

void CDrawView::OnMouseMove(UINT nFlags, CPoint point) 
{
	// TODO: Add your message handler code here and/or call default
	CClientDC dc(this);
	CPen pen(PS_SOLID,0.5,RGB(125,255,110));
	CPen *pOldPen=dc.SelectObject(&pen);
	if(m_bDraw==TRUE)
	{
		dc.SetROP2(R2_BLACK);
		dc.MoveTo(m_ptOrigin);
		//dc.LineTo(point);
		dc.LineTo(m_ptOld);
		//dc.MoveTo(m_ptOrigin);
		dc.MoveTo(m_ptOld);
		dc.LineTo(point);
		//m_ptOrigin=point;
		m_ptOld=point;
	}
	dc.SelectObject(pOldPen);
	CView::OnMouseMove(nFlags, point);
}

但是我在vs2008新建一个MFC应用程序，主要代码一样时，为何不能运行呢，连OnMouseMove，OnLButtonDown，OnLButtonUp都跟不进去，高手指点

你是怎么生成的,上面几个函数你要按照向导生成,或者你手工添加也行,但要加全了,头文件加上声明,CPP文件里加两个地方:一个就是函数实现,就是上面的代码,另一个是关键,就是加函数映射,这样才能响应鼠标的动作
如果你是把上面的代码考过去,那可能是没加函数映射

[写不动代码的人]

你的鼠标消息是由IDE生成的吗

[lionghua]

鼠标事件是自己添加的，因为VS2008中没有classvisual

解决了，谢谢hdg3707和heksn
