Example
CString str;
// Add 1024 items to the list view control.
// Force my virtual list view control to allocate
// enough memory for my 1024 items.
m_myVirtualListCtrl.SetItemCountEx(1024, LVSICF_NOSCROLL|
LVSICF_NOINVALIDATEALL);
for (int i = 0; i < 1024; i+)
{
str.Format(TEXT("item %d"), i);
m_myVirtualListCtrl.InsertItem(i, str);
}
