（5）鼠标弹起函数

void  CRectGraph::RectLButtonUp(UINT nFlags, CPoint point)

{

    RectCoordinateReversal();

    DrawXorRect(0,0,RGB(255,0,0));

    m_bIsDraw = FALSE;

    m_pView->Invalidate(); 

}

（6）鼠标移动函数

void  CRectGraph::RectMouseMove(UINT nFlags, CPoint point)

{

    RectAddCurResourse(point);

    if(!m_bIsDraw) return;

    DrawXorRect(0,0,RGB(255,0,0));

    SetCurRect(point);

    DrawXorRect(0,0,RGB(255,0,0));

    m_pntPrev = point;

}

4.2 辅助功能函数

（1）判断点的位置是在矩形框的什么位置函数

long CRectGraph::JudgePositionInRect (CPoint point)

{

    long lRslt = SUBWIN_OUT;//在右下

    CRect inRect,upRect,downRect,leftRect,rightRect;

    CRect leftupRect,rightupRect,leftdownRect,rightdownRect;

    inRect.left = m_Rect.left+8;                   inRect.top = m_Rect.top+8;
