CTreeCtrl如何在第一个子节点前插入子节点

[piggygy]

InsertItem函数只提供hInsertAfter参数指明在某个节点后插入。
而我想对已有子节点的父节点插入一个排在第一位的子节点，
望高手指教。

HTREEITEM InsertItem(
   LPTVINSERTSTRUCT lpInsertStruct 
);
HTREEITEM InsertItem(
   UINT nMask,
   LPCTSTR lpszItem,
   int nImage,
   int nSelectedImage,
   UINT nState,
   UINT nStateMask,
   LPARAM lParam,
   HTREEITEM hParent,
   HTREEITEM hInsertAfter 
);
HTREEITEM InsertItem(
   LPCTSTR lpszItem,
   HTREEITEM hParent = TVI_ROOT,
   HTREEITEM hInsertAfter = TVI_LAST 
);
HTREEITEM InsertItem(
   LPCTSTR lpszItem,
   int nImage,
   int nSelectedImage,
   HTREEITEM hParent = TVI_ROOT,
   HTREEITEM hInsertAfter = TVI_LAST
);

默认是TVI_LAST
