check the MSDN about the TVN_ITEMEXPANDED windows message.
pNMHDR is actually a pointer to an NM_TREEVIEW structure, in which The itemNew member is a TV_ITEM structure that contains valid information about the parent item in the hItem, state, and lParam members. The action member in NM_TREEVIEW indicates whether the list expanded or collapsed(TVE_COLLAPSE or TVE_EXPAND ).
