请问这个程序段哪里出错了？运行的时候会死掉

太长了
在哪里死掉?

[song1014]

好像问题出在HTREEITEM CParserDlg::FindParentNode(HTREEITEM Node)
这个函数里。NODE_ELEMENT ，NODE_TEXT ，NODE_COMMENT ，NODE_CDATA_SECTION 这几个里面的操作都差不多的。void CParserDlg::DisplayChildren(IXMLDOMNodePtr pParent）里是一个递归操作

跟踪一下看看

[alanwang_]

递归操作就是麻烦,不小心就成死循环了!
同意sjzxyg(小小鸟) 的意见

}
}
这个函数肯定是对的，问题出在下面，可是我看不出，麻烦哪位帮忙看一下

我是要把一个xml文档的节点插到一个树型控件中，hParentNode是用来记录接下来要插的那个节点的父节点的

[song1014]

是不是while语句出错了
