Problem with listening to MdcListEvents in Outlook Form

[Vladimir Chtchetkine]

Somehow no ListBox events are coming to me. I'm pretty sure that I register
for them right (basically it's the same code that I use for other types of
events that ARE coming) but for ListBox I get nothing. Is there anything
special that is need to subscribe to control events (comparing with other
Outlook objects)? Just in case here is source code (sorry for C++ and the
amount, but I exhausted all ideas and really need some help)

Hmmm... What's interesting is that OutlookSpy doesn't even offer (there is
no "Events" tab) to see events on MdcListBox object although it does for
corresponded Control object... Does this mean that there is no such thing as
events from ListBox at all?
