1、CTreeCtrl 树节点排序，节点复选效果描述：该功能可使某义节点下的全部子节点按某种序列重新排列SortChildren 是为该结点下面的所有子节点排序，注意只是子节点，不包括子 节点的子节点。SortChildrenCB 是自定义排序方式。现给出大体例子SortChildrenCB 中的 TVSORTCB 需要用到一个回调函数常常是难点。INT CHvrTree:SortItem(HTREEITEM hItem)BOOL bRet;CHvrTree *ptree = this;TVSORTCB sortpage;g_pLogger-Debug( SortItem():Enter,D_PC
