hi
i use this code to save my preview report.
frxReport1.PreviewPages.SaveToFile('c:\new.fp3');

but when in preview page i used open (icon in toolbar) to load that report
it only show a white page.
why?

it will depend upon where you make this call.
and the code prior to it.
ie
frxreport1.loadfromfile('myreport.fr3');
frxreport1.preparereport;
frxReport1.PreviewPages.SaveToFile('c:\new.fp3');
