The following approach worked perfecly for me:
std::stack< int > items;
int nItem = -1;
while ((nItem = myListCtrl.GetNextItem(nItem, LVNI_SELECTED)) != -1)
{
items.push(nItem);
}
bool removed = false;
while (!items.empty())
{
nItem = items.top();
if (myListCtrl.DeleItem(nItem))
removed = true;
items.pop();
}
if (removed)
// update some application state;
Explanation:
When you remove things from the end to the start, you do not have to worry about the validity of positions. As the CListCtrl does not provide a GetPrevItem or any other way to get items in the reverse order, you need to store them in a collection where you can have that reverse order.
The most practical way to do it is to use a stack. Due to the way it works, you will put things in there in the normal order, and when you retrieve things they are automatically in reverse order.
