HRESULT FoldersTree_BlessItem(HWND hwnd, HTREEITEM hItem)
[in] HWND hwnd
[in] HTREEITEM hItem
This function 'blesses' item. Every item, inserted in a FoldersTree
control not by FoldersTree API (but for example by
TreeView_InsertItem
) must be 'blessed' by calling this
function before calling any other FoldersTree API functions on this control.
(So it should be 'blessed' immediately after insertion.)
After calling this function the item is not associated.
Associated items must not be 'blessed' by you.
