When I create subitems for a list control, do I need to dynamically allocate 
memory for text items, then free that memory on item destruction? Or does 
the CListCtrl automatically make a copy of any string I assign to it for 
subitems and automatically free the memory?

For example, would the following be valid? does the ListView_SetItem() make 
a copy of the text assigned to lvi.pszText?

==== sample below ======

LVITEM lvi;
lvi.mask = LVIF_TEXT;

CString strName="Some Name";
CString strStatus="Some Status";

for ( i = 0; i < x; i++ )
{
 m_ctrlPackageList.InsertItem( i, strName );

 lvi.iItem = i;
 lvi.iSubItem = 1;
 lvi.pszText = strStatus;
 lvi.cchTextMax = strStatus.GetLength();

 ListView_SetItem( m_ctrlPackageList, &lvi );
}

You don't need to dynamically allocate memory for text items of a listview 
control, the general convention is to use auto string objects(local 
varibles which created on stack just as your code snippet).The CListCtrl 
will make a copy of the text item's string for its own use and manage it 
automatically.


Thanks!
