list index out of bounds (-1 )

Hoa

I had the code snip below which was working well in 3.x and 4.09. However after I upgrade to 4.10, it stop working, and cause a crash with error message of [ List Index out of bound (-1) ].


TfrxReportPage *frxPage = new TfrxReportPage ( frxReportX );


if ( frxPage ) {
frxReport2->PrepareReport( true );
frxPreview2->LoadFromFile( filename1 );

frxReportX->PrepareReport( true );
ok = frxReportX->PreviewPages->LoadFromFile( filename2 );

frxReportX->PreviewPages->AddFrom( frxReport2 );
/**************************

frxReportX->PrepareReport( false );
//frxPreview3->Show();
int npgcount = frxReportX->PreviewPages->Count;
frxReportX->PreviewPages->SaveToFile ("c:\\temp\\combined.fp3");
frxPreview2->LoadFromFile( "c:\\temp\\combined.fp3" );
}
delete frxReportX;
}
frxPreview2->Show();
