var
  hi : HTreeItem
  Item: TTVItem;
begin
  hi:=TreeView_GetSelection(Handle); //  the handle of the treeview
  Item.hItem := hi;
  Item.mask := TVIF_PARAM;
  if TreeView_GetItem(Handle, Item) then Result := TTreeNode(Item.lParam)
end;

i produced this example while looking into unit ComCtrls.pas:

function TCustomTreeView.GetSelection: TTreeNode;
and
function TTreeNodes.GetNode(ItemId: HTreeItem): TTreeNode;

and also Commctrl.pas:
function TreeView_GetSelection(hwnd: HWND): HTreeItem;
and
function TreeView_GetItem(hwnd: HWND; var pitem: TTVItem): Bool;


regards,
ewilde.
