pToolBar2 = NULL;

2. add in CMainFrame::OnCreate

pToolBar2 = (CXTPToolBar*)pCommandBars->Add(_T("Standard2"), xtpBarTop);

// .... //

3. int CMainFrame::ValidToolBar(void)
{
     if(pToolBar2->IsVisible())
    {
       pToolBar2->SetVisible(FALSE); AfxMessageBox(" hide toolbar2~ ^^ ");
    }
    else
    {
        pToolBar2->SetVisible(TRUE); AfxMessageBox(" show toolbar2~ ^^ ");
    }

return 0;
}

4. button of pane that i make.

void CNavigationView::OnBnClickedOk()

It can happens if you Save State in OnDestroy instead of OnClose.

Show me how you save it.

hello, thanks a lot.

i didn't use OnDestroy and use OnClose.

void CMainFrame::OnClose()
{

// Save the current state for toolbars and menus.
SaveCommandBars(_T("CommandBars"));

    // Save the current state for docking panes.
    CXTPDockingPaneLayout layoutNormal(&m_paneManager);
    m_paneManager.GetLayout(&layoutNormal);
    layoutNormal.Save(_T("NormalLayout"));

CMDIFrameWnd::OnClose();

}

The main points may be summarized as follows.

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    // i use "pToolBar2" instead of "CXTPToolBar* pToolBar2"
    pToolBar2 = (CXTPToolBar*)pCommandBars->Add(_T("Standard2"), xtpBarTop);
    if (!pToolBar2 || !pToolBar2->LoadToolBar(IDR_TOOLBAR2))
    {
        TRACE0("Failed to create toolbar2\n");
        return -1;
    }
}

so, before that,

class CMainFrame : public CXTPMDIFrameWnd
{
protected:
CXTPToolBar* pToolBar2; // declaration.
}
and,

CMainFrame::CMainFrame()
{
pToolBar2 = NULL;
}

used as above.

1. when using commonly "CXTPToolBar* pToolBar2" in OnCreate() and application end , error is not occur.
2. But... when using as above code and application end , error message occured with debbuging window.
