can not get correct data from oddbole2frame!

and what is crectitem ???
crectitem inherit coleclientitem...
crectitem inherits coleclientitem,such as
class crectitem : public coleclientitem
{
......
}.
i'm sure that class crectitem has no problem.because the code as follow is ok.
oddbole2frameptr oleentity =(oddbole2frameptr)pmsent;
{
crectitem *ole =(crectitem *)createole();
cfile file0;
file0.open("c:\\acmilan1.txt",cfile::modereadwrite |cfile::sharedenynone);
file0.flush();
file0.seektobegin();
carchive archive(&file, carchive::load);
archive.m_pdocument = g_ole_doc;
ole->serialize(archive);fff">//every is ok.ole entity can display correctly.
file.close();
}
attention to the difference between acmilan1.txt and acmilan.txt.
i found that only the heads of the two files are different.
how can i get data such as acmilan1.txt ,but not acmilan.txt .
thanks a lot.

hi,
now i see!
replace
oleentity->getcompounddocument(*pfile);
with
oleentity->itemhandler()->save(*pfile);
to get data that you want.
now every is ok.
thanks very much!
