acdbdatabase* polddb = acdbhostapplicationservices()->workingdatabase();
acdbdatabase* pnewdb = new acdbdatabase();
acdbhostapplicationservices()->setworkingdatabase(pnewdb);
''''''//执行数据写入操作

pnewdb->saveas(_t("routetable.dwg"));
acdbhostapplicationservices()->setworkingdatabase(polddb);
delete pnewdb;
编绎是没问题的,但在加载arx后,执行此段,报错,访问拒绝,,,
我把pnewdb->saveas(_t("routetable.dwg"));注释掉后,运行没反映,但是什么文件也没生成.
你粘贴的啊 ！我在这里写的，没有运行，应该没有问题。
void xb()
{
acdbdatabase *pdb=new acdbdatabase();
acdbblocktable *pblktb;
pdb->getsymboltable(pblktb,acdb::kforread);
acdbblocktablerecord *pblktbrcd;
pblktb->getat(acdb_model_space,pblktbrcd,acdb::kforwrite);
pblktb->close();
acdbcircle *pcircl=new acdbcircle(acgepoint3d(1,1,1),acgevector3d(0,0,1),1.0);
acdbcircle *pcirc2=new acdbcircle(acgepoint3d(4,4,4),acgevector3d(0,0,1),2.0);
pblktbrcd->appendacdbentity(pcircl);
pblktbrcd->appendacdbentity(pcirc2);
pcircl->close();
pcirc2->close();
pblktbrcd->close();
pdb->saveas("tt.dwg");
delete pdb;
}
