BOOL SetItemCountEx(
   int iCount,
   DWORD dwFlags = LVSICF_NOINVALIDATEALL 
);
Parameters
- iCount 
 Number of items that the control will ultimately contain.
- dwFlags 
 Specifies the behavior of the list view control after resetting the item count. This value can be a combination of the following:
- LVSICF_NOINVALIDATEALL The list view control will not repaint unless affected items are currently in view. This is the default value. 
- LVSICF_NOSCROLL The list view control will not change the scroll position when the item count changes. 
Return Value
Nonzero if successful; otherwise zero.
Remarks
This member function implements the behavior of the Win32 macro, ListView_SetItemCountEx, as described in the Windows SDKand should only be called for virtual list views.
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);
}
