bool isfind=false;
oddbblocktableptr pblocks =
getdocument()->m_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();

// pblock->getname().c_str();
// get an entity iterator
oddbobjectiteratorptr pentiter = pblock->newiterator();
// for each entity in the block
for (; !pentiter->done(); pentiter->step())
{
oddbattributedefinitionptr pent = oddbattributedefinition::cast(pentiter->objectid().openobject(oddb::kforwrite));
if (!pent.isnull())
{
if (pent->tag()==odstring(aduititem))
{
pent->settextstring(odstring(aduitinfo));
isfind=true;
// break;
}
if (pent->tag()==odstring(aduititem+"日期"))
{
ctime t = ctime::getcurrenttime();

pent->settextstring(odstring(t.format("%y 年 %d 月 %b")));
isfind=true;
// break;
}
}
// dumpentity(pentiter->objectid(), os);
getdocument()->onsavedocument(openingfile);
}
}
return isfind;
from developer's guide (faq)
oddbdatabase::writefile() is throwing an ewasopenforwrite exception when i try to save out a dwg/dxf drawing.
this error generally occurs when an object in the database was modified, and was not closed by the user (for example, if the client code retains a smart pointer to the modified object). closing the object (releasing the smart pointer) prior to calling oddbdatabase::writefile(), should fix the problem.
