save dwg file problem!
i want edit the attribute in block,but save the dwg file problem,please help me!
the code run in odamfcapp is right,but in my app error!
the code is:
code:
bool cdwgviewer::writeaduitinfo(cstring aduititem,cstring aduitinfo)
{
// open the block table
bool isfind=false;
oddbobjectptr pobject;
oddbobjectid id;
oddbdatabase* pdb = getdocument()->m_pdb;
oddbblocktableptr pblocks =
pdb->getblocktableid().safeopenobject();

// get an iterator for the block table
oddbsymboltableiteratorptr pblkiter = pblocks->newiterator();

// for each block in the block table
for (pblkiter->start(); ! pblkiter->done(); pblkiter->step())
{
// open the block
oddbblocktablerecordptr pblock =
pblkiter->getrecordid().safeopenobject(oddb::kforwrite);

// get an entity iterator
oddbobjectiteratorptr pentiter = pblock->newiterator();

// for each entity in the block
for (; !pentiter->done(); pentiter->step())
{
id=pentiter->objectid();
oddbentityptr pent = id.safeopenobject(oddb::kforwrite);
//messagebox(pent->layer(),_t("test"),mb_ok);
oddbblockreferenceptr pblock=oddbblockreference::cast(pent);
if (!pblock.isnull())
{
oddbblocktablerecordptr precord = pblock->blocktablerecord().safeopenobject(oddb::kforwrite);
oddbobjectiteratorptr piter = pblock->attributeiterator();
for (int i=0; !piter->done(); i++, piter->step())
{
oddbattributeptr pattr = oddbattribute::cast(piter->objectid().openobject(oddb::kforwrite));
if (!pattr.isnull())
{
if (pattr->tag()==odstring(aduititem))
{
pattr->settextstring(odstring(aduitinfo));
isfind=true;
// break;
}
}
}
}
}
}
cstring newname = "d:/3.dwg";
pdb->writefile(odstring(newname),oddb::kdwg,oddb::vac18,true);
// getdocument()->onsavedocument(newname);
return isfind;
}
