Are you talking about the

I'm not sure I understand what you want to confirm. when you click on a tree item, you will have a TVN_SELCHANGED notification ( add an handler for that ), in the handler you will receive the HTREEITEM that is selected. something like :
void MyTree::OnTreeSelchanged( NMHDR* pNMHDR, LRESULT* pResult )
{
NM_TREEVIEW* pNMTreeView = (NM_TREEVIEW*)pNMHDR;
HTREEITEM item = pNMTreeView->itemNew.hItem;
}if you want to check for a "hardcoded" string, CTreeCtrl::GetItemText( ... ) might be what you want to check for. otherwise, I'm not certain.

look at this figure: ----------------- 1 --1-------------- 2 ---1。1-------- 3 ---1。2-------- 4 ---1。3-------- 5 --2-------------- 6 ---2。1-------- 7 ---2。2-------- 8 ---2。3-------- 9 you know when i click the item for example item 4 which is"---1。2--------"; the question is how can i know that i clicked the item is item4 not others by code in my function OnSelchangedTree1(NMHDR* pNMHDR, LRESULT* pResult) ? that means how to judge the item clicked is the one i want in code. your hint using GetItemText( ... ) maybe bot work when my item text is put dynamically,for you even not konw the exact text. 路漫漫其修远兮，吾将上下而求索。

NMTREEVIEWstructure, specifically theitemNewmember. try88 wrote: your hint using GetItemText( ... ) maybe bot work when my item text is put dynamically,for you even not konw the exact text. What? How else are you going to add text if not dynamically? Tree controls are not populated at design/compile time. If an item has text, that text can be retrieved viaGetItemText(). Have you looked at the documentation for how this function works?

HTREEITEM item = pNMTreeView->itemNew.hItem;tells you what item you clicked on. if you add things dynamically to the tree, you will need to attach some kind of user data to each item ( or leaves ) of the tree withCTreeCtrl::SetItemDatato identify it. besides, your figure it not clear at all; what is the tree data ? what is the item number ?
