Does anyone know how to make use of the LVN_ITEMACTIVATE notification?

I've tried several ways: The notification is neither sent to the OnChildNotify() message
handler nor to an explicitely defined message handler like this
ON_NOTIFY(LVN_ITEMACTIVATE, IDC_LISTCTRL, OnItemActivateListCtrl).

Currently I'm catching NM_CLICK and NM_RCLICK notifications. This works ok for
mouse clicks; however I can't handle keyboard inputs since LVN_KEYDOWN messages
are sent to me BEFORE the item changes.

Maybe you have another idea how to catch a change of the currently selected list control item.

I'm a little confused because the LVN_ITEMACTIVATE message is written in the documentation
but seems not to be sent. A little strange, I think...

Thanx for help,
Torsten
