If it's a generic object then copy it's storage under the destination storage unchanged. If it's one of the special things that have an analogue in the destination format save it to a temporary storage in another format and copy that into the destination format instead. //export to temporary stream "pStream" ::uno::Reference < io::XOutputStream > xOut = new ::utl::OOutputStreamWrapper( *pStream ); aSeq[0].Value <<= xOut; xStor->storeToURL( ::rtl::OUString( RTL_CONSTASCII_USTRINGPARAM( "private:stream" )), aSeq ); //copy result to destination ole2 storage SotStorageRef xOLEStor = new SotStorage( pStream, sal_True ); xOLEStor->CopyTo( &rDestStg ); > I already have a pointer to SmModel and SmDocShell (I can get it the same way > the .doc code does) and just need to call their method, passing the XML > serializer object as an argument, that's it. Probably matters what the destination format is like ? Is it a standalone thing and/or exists in a substorage/folder of the parent format where it doesn't care about what it is inside ? i.e. I'd sort of expect to basically just add another export filter to starmath for whatever that format is, add it to SmDocShell::ConvertTo and call that directly/indirectly. And have a save as... entry for the format if it makes sense to have it standalone ? That's not going to work if the destination format needs hooks back into its surrounding container. Is that the problem ? C. _______________________________________________ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
