遍历失败

<p>我想遍历打开文件中的实体，程序如下：es =pBlockTableRecord4-&gt;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+autocad2007+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。</p><p>AcDbDatabase *pCurDb = NULL;<br/>&nbsp; Acad::ErrorStatus es;<br/>int i;<br/>AcDbBlockTable *pBlockTable4;</p><p>acDocManager-&gt;lockDocument( acDocManager-&gt;curDocument(), AcAp::kWrite, NULL, NULL,true) ;</p><p>pCurDb = acdbHostApplicationServices()-&gt;workingDatabase();<br/>&nbsp;&nbsp;&nbsp; es =pCurDb-&gt;getSymbolTable(pBlockTable4, AcDb::kForRead);//<br/>&nbsp;if (es != Acad::eOk) {<br/>acutPrintf(_T("\ngetSymbolTable!"));<br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<br/>acutPrintf(_T("\n2!"));<br/>&nbsp;&nbsp;&nbsp; AcDbBlockTableRecord *pBlockTableRecord4;<br/>&nbsp;&nbsp;&nbsp; es =pBlockTable4-&gt;getAt(ACDB_MODEL_SPACE, pBlockTableRecord4,AcDb::kForWrite);<br/>&nbsp;if (es != Acad::eOk) {<br/>acutPrintf(_T("\ngetAt!"));<br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<br/>acutPrintf(_T("\n3!"));<br/>&nbsp;&nbsp; <br/>AcDbBlockTableRecordIterator *pIter;<br/>&nbsp; //AcDbBlockTableRecordPointer pBTR(ACDB_MODEL_SPACE,acdbHostApplicationServices()-&gt;workingDatabase(),AcDb::kForRead);</p><p>es =pBlockTableRecord4-&gt;newIterator(pIter);&nbsp; //获得遍历指针,true,true<br/>acutPrintf(_T("\n5!"));<br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (es != Acad::eOk) {<br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; acutPrintf(_T("\ngetAt!"));<br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }</p><p></p>

大家都没遇到这种情况？是我装的autocad有问题？
