How to get current page number (SDK, C++)

Hi

I'm trying to get current page index / number inside a find text loop. Here's my code

 Utils<ILayoutUtils>()->InvalidateViews(document);
                    InterfacePtr<ILayoutControlData> layoutCData(ac->GetContextView(),UseDefaultIID() );

                    InterfacePtr<IHierarchy> layerHier(layoutCData->QueryActiveLayer());
                    UIDRef layerRef(::GetUIDRef(layerHier));
                    IDataBase* db = layerRef.GetDataBase();
                    UIDRef pageRef = UIDRef(db, layoutCData->GetPage());
                    
                    InterfacePtr<ISpread> cspread(layoutCData->GetSpreadRef(), IID_ISPREAD);
                    int32 pageIndx = cspread->GetPageIndex(pageRef.GetUID());
                    
                    PMString info("pidx: ");
                    info.AppendNumber(pageIndx);
                    CAlert::InformationAlert(info);

I used these too to refresh

sleep_for(10ms);

Utils<ILayoutUtils>()->InvalidateViews(document);

But it just gives me 0 always. Please guide me where im wrong.

thank you
