I am creating a listview with the following statement
m_pListView->Create( WS_VISIBLE | LVS_SINGLESEL | LVS_NOSORTHEADER | LVS_SHOWSELALWAYS | LVS_REPORT, rect, this, ID_LISTVIEW );
This code comes from an example in a book. The problem is that no explanation is given as to where to declare ID_LISTVIEW and what number to make it. If I just use 120 it works but I would like to be a bit more certain about what is going on. All help will be greatly appreciated.
