我想遍历打开文件中的实体，程序如下：es =pBlockTableRecord4->newIterator(pIter); 运行到这句就报错，unhandled exception 之类的，这段代码我原来在2002上用没问题的。大家有遇到这种问题吗？我的编程环境：vs2005+2007+objectarx2007.而且我把代码中的遍历类型换成层遍历，又可以正常运行，挺奇怪的。
AcDbDatabase *pCurDb = NULL;
Acad::ErrorStatus es;
int i;
AcDbBlockTable *pBlockTable4;
acDocManager->lockDocument( acDocManager->curDocument(), AcAp::kWrite, NULL, NULL,true) ;
pCurDb = acdbHostApplicationServices()->workingDatabase();
es =pCurDb->getSymbolTable(pBlockTable4, AcDb::kForRead);//
if (es != Acad::eOk) {
acutPrintf(_T("\ngetSymbolTable!"));
}
acutPrintf(_T("\n2!"));
AcDbBlockTableRecord *pBlockTableRecord4;
es =pBlockTable4->getAt(ACDB_MODEL_SPACE, pBlockTableRecord4,AcDb::kForWrite);
if (es != Acad::eOk) {
acutPrintf(_T("\ngetAt!"));
}
acutPrintf(_T("\n3!"));
AcDbBlockTableRecordIterator *pIter;
//AcDbBlockTableRecordPointer pBTR(ACDB_MODEL_SPACE,acdbHostApplicationServices()->workingDatabase(),AcDb::kForRead);
es =pBlockTableRecord4->newIterator(pIter); //获得遍历指针,true,true
acutPrintf(_T("\n5!"));
if (es != Acad::eOk) {
acutPrintf(_T("\ngetAt!"));
}
