How to get selected items from window desktop?

I need to obtain selected items located in a window desktop (files and
folders) in current moment. I know how to obtain selected items in window
explorer using shell32 object and how to get just all desktop items. But
how to find out which of them are selected in current moment I don't know.
I find code snippet in question Get selected items of folder with WinAPI.
It probably allows to get selected items in desktop but I think that this
is hack style code and it can deliver problems on other versions of OS
language: C#
