我得到数据字典类时,出现异常,不知道为什么,谢谢,下面是代码.

    AcDbDictionary *pNamedobj;
    acdbHostApplicationServices()->workingDatabase()
        ->getNamedObjectsDictionary(pNamedobj, AcDb::kForRead);

    // Get a pointer to the ASDK_DICT dictionary.
    //
    AcDbDictionary *pDict;
    pNamedobj->getAt("SCALE_DICT", (AcDbObject*&)pDict,
        AcDb::kForRead);
    pNamedobj->close();

    // Get an iterator for the ASDK_DICT dictionary.
    //
    if (pDict == NULL) {//pDict不为空
        ASSERT(0);
        return;
    }
    AcDbDictionaryIterator* pDictIter= pDict->newIterator();//在这句后出现异常[/COLOR]
    BSCScaleClass *pMyCl;
   
    for (; !pDictIter->done(); pDictIter->next()) {

        // Get the current record, open it for read, and
        // print its data.
        //
        pDictIter->getObject((AcDbObject*&)pMyCl,
            AcDb::kForRead);
        pMyCl->gethScale(hs);
  pMyCl->getvScale(vs);
        pMyCl->close();
        acutPrintf("\nintval is:  %d", hs);
    }
    delete pDictIter;
    pDict->close();
