delphi - Connect Excel WorkSheet in OleContainer -

i need connect excel worksheet in olecontainer. can do, saving worksheet in disk:

// worksheet , save disk globals.xls.gethoja().saveas('d:\test.xls',...,emptyparam,emptyparam,emptyparam); // load worksheet disk olecontainer.createobjectfromfile('d:\test.xls',false); 

but, exist way, connect without save worksheet ?. ergo, load inside olecontainer instance of _worksheet returned globals.xls.gethoja().
