The code is following:

LRESULT CEventBrowserView::OnDockingPaneNotify(WPARAM wParam, LPARAM lParam)
{
if (wParam == XTP_DPN_SHOWWINDOW)
{
  CXTPDockingPane* pPane = (CXTPDockingPane*)lParam;
  if((!pPane->IsValid()) && (pPane->GetID() == ID_DOCK))
  {
   if(!m_pOptionView)
    m_pOptionView = DYNAMIC_DOWNCAST(CEventBrowserOptionView,
     pPane->AttachView(this, RUNTIME_CLASS(CEventBrowserOptionView)));
   if(m_pOptionView->GetSafeHwnd())
   {
    pPane->SetTitle(_T("事件列表查询选项"));
    pPane->SetMaxTrackSize(CSize(0,60));
   }
  }
}
return TRUE;
}

the CEventBrowserOptionView is inherited from CView,while i run it in degbug mode everything is ok,but while i'm using release mode,there'll be an error happened when i close the CEventBrowserView.

Is there any special requirements for the CEventBrowserOptionView?

HELP!!!! please

Hi;

Have you tried to overload CView::PostNcDestroy(). The default implementation calls delete this;
Perhaps the view object will be deleted twice, because panes are derived from CCmdTarget and InternalRelease() will be called -> CCmdTarget::OnFinalRelease() also calls delete this!
