MFC / C++: What message indicates that the selection of a CListCtrl has changed?

Hello,

I have a ClistCtrl in a dialog that displays data that can be changed with/are reflected by various form widgets, mostly CEdits. I'd like to catch any MFC messages sent by the CListCtrl that indicate that the user's focus has changed (i.e that they have clicked on a different row of the ClistCtrl), so that I can update the form widgets as appropriate.

How can this be done?

You can use LVN_ODSTATECHANGED

BEGIN_MESSAGE_MAP(CBatchAdd, CDialog)
NOTIFY_HANDLER(IDC_LIST_PRODUCTS_ADDED, LVN_ODSTATECHANGED,&CBatchAdd:: OnListSelChanged)
END_MESSAGE_MAP()

This seems to cause all kinds of errors. I guess I got something wrong. What should I do to handle the message?

try this:

NOTIFY_HANDLER(IDC_LIST_PRODUCTS_ADDED, LVN_ODSTATECHANGED, OnListSelChanged)

Curiously, this causes the following error message:

error C3861: 'NOTIFY_HANDLER': identifier not found

Plus a whole bunch of syntax errors arising from that.

Is this an MFC handler or an ATL handler?

It's an ATL handler.

Try the following:

ON_NOTIFY_REFLECT(LVN_ODSTATECHANGED, OnListSelChanged)

void CBatchAdd::OnListSelChanged( NMHDR *pNMHDR, LRESULT *pResult )
{
LPNMLVODSTATECHANGE pNMLV = reinterpret_cast<LPNMLVODSTATECHANGE>( pNMHDR );
...
}
