SDI app and CChartCtrl in view

I have an app that I'm porting to use XTP 8.51. This SDI app has a view for a graph. I created a blank SDI app, put in the pane code, etc. but my chart doesn't get drawn to the pane. I've traced through the code some, and it appears that my chart code is being constructed properly, etc. Any ideas why it might not be drawing to the pane?

I used samples\Common\Advanced\HeroesView.h as an example. I have ChartView.h and ChartView.cpp. In CChartView::InitialUpdate(), I construct the chart object, draw some axis and labels, etc. MainFrm.cpp has the docking pane notify message, which gets called.

LRESULT CMainFrame::OnDockingPaneNotify(WPARAM wParam, LPARAM lParam)
{
if (wParam == XTP_DPN_SHOWWINDOW)
{
CXTPDockingPane* pPane = (CXTPDockingPane*)lParam;
       
if (!pPane->IsValid())
{
   switch (pPane->GetID())
   {
    case ID_PANE_CHART:
     if (m_pChartView == 0)
     {
       m_pChartView = new CChartView();
       m_pChartView->C reate(_T("STATIC"), NULL, WS_CHILD, CRect(0, 0, 0, 0), this, 0);
       ((CChartView*) m_pChartView)->OnInitialUpdate();
     }      ;     
     pPane->Attach(m_pChartView) ;
     break;
   }
   return TRUE;
}
return FALSE;
}

Problem solved. The Advanced demo uses CNoFlickerWnd. I had my variables declared of that type. Once I removed it, everything worked.
