从一个数组中生成一棵树的问题，帮我看看代码哪儿有问题？

[cdpcsc]

typedef list<void*> PtrList
参数lst里大概有90来个CDepartmentInfo类型指针，下面的代码在lst里大概还有30多个的时候 貌似it失效了，会异常。

void CBargainDlg::InsertItemByArray(PtrList& lst, unsigned int depid /*= 0*/, HTREEITEM hItem /*= TVI_ROOT*/)
{
	PtrList::iterator it = lst.begin();
	while ( it != lst.end() )
	{
		CDepartmentInfo *p = ( CDepartmentInfo * ) * it;
		if( p->parentid == depid )
		{
			it = lst.erase( it );
			hItem = m_ColleagueTree.InsertItemEx( p->id, p->strName,TVECID, TVEIID,hItem );
			InsertItemByArray( lst, p->id, hItem );
			int a= 5;
		}
		else
			++it;
	}
}

其中CDepartmentInfo的定义为

class CDepartmentInfo: public CObject
{
public:
	unsigned int id;
	unsigned int parentid; //0表示根节点
	CString strName;
};

不过你说说造成的原因，解决的方法撒？所谓前人栽树，后人乘凉......

OK了

void CBargainDlg::InsertItemByArray(PtrList &lst, unsigned int depid /*= 0*/, HTREEITEM hPItem /*= TVI_ROOT*/)
{
	PtrList::iterator it = lst.begin();
	while ( it != lst.end() )
	{
		CDepartmentInfo *p = ( CDepartmentInfo * ) * it;
		if( p->parentid == depid )
		{
			HTREEITEM hItem = m_ColleagueTree.InsertItemEx( p->id, p->strName,TVECID, TVEIID,hPItem );
			InsertItemByArray( lst, p->id, hItem );
			it = lst.erase( it );
		}
		else
			++it;
	}
}

OK了
C/C++ code

void CBargainDlg::InsertItemByArray(PtrList &lst, unsigned int depid /*= 0*/, HTREEITEM hPItem /*= TVI_ROOT*/)
{
PtrList::iterator it = lst.begin();
while ( it != lst.en……

OK了 就jf~
