紧急求救！关于dbx中的blocktablrecord的迭代器问题，有代码
acdbdatabase db(adesk::kfalse);
acad::errorstatus err;
err = db.readdwgfile((const char*)szprojdbpath,_sh_denyno,adesk::kfalse);
acdbblocktable *pblocktable = null ;
err = db.getsymboltable(pblocktable, acdb::kforread);
acdbblocktablerecord *pblocktablerecord = null;
err = pblocktable->getat(acdb_model_space, pblocktablerecord,
acdb::kforread);
pblocktable->close();
acdbblocktablerecorditerator* piterator = null;
err = pblocktablerecord->newiterator(piterator,true,false);
为何上述代码在arx工程中执行的不错，而在dbx中就挂了??告诉我是createfailed（最后一句） 请大侠帮个忙拉
