I wonder what exactly is the role of GetListCtrl(); generate a instance of ListCtrl? or sth else?

However, what if there are more than one list controls associated with the view.

You mean ONLY one ListCtrl can be associated with one view?

If so, Why there may be more than one ListCtrl in a dialog

for a view derived from a CFormView, how to get the references of ListCtrls associated with it.

CListView::OnInitialUpdate();

void CMyListView::OnInitialUpdate()
{
   CListView::OnInitialUpdate();

   // this code only works for a report-mode list view
   ASSERT(GetStyle() & LVS_REPORT);

   // Gain a reference to the list control itself
   CListCtrl& theCtrl = GetListCtrl();

   // Insert a column. This override is the most convenient.
   theCtrl.InsertColumn(0, _T("Player Name"), LVCFMT_LEFT);

   // The other InsertColumn() override requires an initialized
   // LVCOLUMN structure.
   LVCOLUMN col;
   col.mask = LVCF_FMT | LVCF_TEXT;
   col.pszText = _T("Jersey Number");
   col.fmt = LVCFMT_LEFT;
   theCtrl.InsertColumn(1, &col);

   // Set reasonable widths for our columns
