CView : creation

I use two class in a none doc\view application. The first one is derive from CMDIChildWnd and the second one is derive from CView. I Create the CMDIChildWnd this way :

HTML Code:

---

pFrame->CreateNewChild( RUNTIME_CLASS(WndGridChild), IDR_INTERFTYPE, m_hMDIMenu, m_hMDIAccel);

---

The CView derived class is create this way :

Code:

---

BOOL WndGridChild::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo)
{
        if (m_GridView->OnCmdMsg(nID, nCode, pExtra, pHandlerInfo))
                return TRUE;
       
        return CMDIChildWnd::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);
}

BOOL WndGridChild::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
        pContext->m_pNewViewClass = RUNTIME_CLASS(CGridView);

        m_GridView = (CGridView*)CreateView(pContext);

        if(NULL == m_GridView)
        {
                return FALSE;
        }
       
        return CMDIChildWnd::OnCreateClient(lpcs, pContext);
}

---

When I create this window I don't why it call 2 times all functions for View creation ( OnInitialUpdate, PreCreateWindow, Constructor etc ).

Evedently I would like it call it one time.

Thank you

This is because you create two views.
Do this:

Code:

---

BOOL WndGridChild::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
        pContext->m_pNewViewClass = RUNTIME_CLASS(CGridView);
       
        m_GridView = (CGridView*)CreateView(pContext); //Cretes view
       
        if(NULL == m_GridView)
        {
                return FALSE;
        }
        return TRUE;
        //return CMDIChildWnd::OnCreateClient(lpcs, pContext); //creates view
}

---

Or this:

Code:

---

        BOOL WndGridChild::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
        {
                pContext->m_pNewViewClass = RUNTIME_CLASS(CGridView);
               
                return CMDIChildWnd::OnCreateClient(lpcs, pContext);
        }

Thank you very much for your reply, it is exactly what I want to know
