CListCtrl::SetItemCountEx

Sets the item count for a virtual list view control.

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);
}
