我用CFormView创建了四个对话框，然后在框架里显示，但是当我隐藏原先的对话框时就出错，不知为什么。代码如下：
CView* pOldActiveView = NULL;
CView* pNewActiveView = NULL;

switch(m_nCurrentView)
{
case VIEW_FV1 :
{
pOldActiveView = (CView*)&m_pFV1;
break;
}
case VIEW_FV2 :
{
pOldActiveView = (CView*)m_pFV2;
break;
}
case VIEW_FV3 :
{
pOldActiveView = (CView*)m_pFV3;
break;
}
case VIEW_FV4:
{
pOldActiveView = (CView*)m_pFV4;
break;
}
}

switch (nView)
{
case VIEW_FV1 :
{
pNewActiveView = (CView*)&m_pFV1;
break;
}
case VIEW_FV2 :
{

pNewActiveView = (CView*)m_pFV2;
break;
}
case VIEW_FV3 :
{
pNewActiveView = (CView*)m_pFV3;
break;
}
case VIEW_FV4 :
{
pNewActiveView = (CView*)m_pFV4;
break;
}
}

if(pNewActiveView)
{
if (pOldActiveView == pNewActiveView)
return ;

m_nCurrentView = nView;
pNewActiveView->ShowWindow(SW_SHOWMAXIMIZED);
pNewActiveView->SetDlgCtrlID(AFX_IDW_PANE_FIRST);
pOldActiveView->ShowWindow(SW_HIDE);//出错位置！！！
pOldActiveView->SetDlgCtrlID(m_nCurrentView);

RecalcLayout();
}
}

case VIEW_FV1 :
{
pOldActiveView = (CView*)&m_pFV1;//看这里
break;
}

m_pFV1已经是指针了吧？
不再需要“&”了


and:

case VIEW_FV1 :
{
pNewActiveView = (CView*)&m_pFV1;
break;
}
