如何显示鼠标移动

[tyanfeng_00]

:OnLButtonUp
HDC hdc;
hdc= ::GetDC(m_hWnd);
MoveToEx(hdc,m_start.x,m_start.y,NULL);
LineTo(hdc,point.x,point.y);
::ReleaseDC(m_hWnd,hdc);为鼠标弹起的，如何才能让显示出鼠标移动画线

OnMouseMove

[Gloveing]

void CMyView::OnMouseMove(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
CDC* pDC=GetDC();
pDC->MoveTo(point.x,point.y);
pDC->LineTo(point.x,point.y+2);
//大致就能看到鼠标轨迹了
CView::OnMouseMove(nFlags, point);
}

[写不动代码的人]

void CMyView::OnMouseMove(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
CDC* pDC=GetDC();
pDC->SetPixel(point, RGB(255,0,0);
::ReleaseDC(pDC);

CView::OnMouseMove(nFlags, point);
}

可不可是鼠标按下的时候移动显示直线，弹起的时候停止显示鼠标移动！

完全是类似的操作嘛，只是还要再处理WM_LBUTTONDOWN、WM_LBUTTONUP消息
