块引用explode的问题

SBW8

ads_name en;
ads_point pt;
AcDbObjectId eId,pId;
AcDbVoidPtrArray aryId;
AcDbEntity *pIte;
AcDbBlockTable *pTb;
AcDbBlockTableRecord *pBlockTableRecord;
if(RTNORM==ads_entsel("\nSelect a object:",en,pt));
{
if (Acad::eOk==acdbGetObjectId(eId,en))
{
AcDbEntity *pEnt;
AcDbObjectId id;
if (Acad::eOk == acdbOpenObject(pEnt,eId,AcDb::kForWrite))
{
ads_printf("\nExplodeName= %s",pEnt->isA()->name());
if (Acad::eOk==pEnt->explode(aryId))
{
pEnt->erase();
for(int i=0;i<aryId.length();i++)
{
pIte=(AcDbEntity*)aryId.at(i);
ads_printf("\nExplodeName= %s",pIte->isA()->name());
acdbCurDwg()->getBlockTable(pTb,AcDb::kForRead);
pTb->getAt(ACDB_MODEL_SPACE, pBlockTableRecord,AcDb::kForWrite);
pTb->close();
pBlockTableRecord->appendAcDbEntity(pId,pIte);
pBlockTableRecord->close();
pIte->close();
}
}else
{
ads_printf("\nExplode failed!");
}
}
pEnt->close();
}
} 代码对AcDbBlockReference的实体无效，总是返回failed，请问explode方法对块引用无效吗？

炸开只是虚的而已；实炸有个函数可调用的，到帮助文件里找找了；我只看过，没用过。不知道好不好用

explode函数对与定制实体需要重载，但是对于autocad本身的实体类型是不需要的。它返回explode后的实体的集合，你只要把他们加入数据库，然后删除原来的实体就可以了。但是对与AcDbBlockReference的对象就是不行。。。


还有人解答吗？
