Hi Netters!


Turbo Vision 2 questions:

In TListBox when I want to actualize my List, I make a copy,
for instance PomList, and then add or remove particular
elements of the list and at last execute : MyListBox^.NewList(PomList).
I do it, because TListBox.List is readonly, but I have to have 2 times more
memory needed during this operation. Is there any simpler and less
memory_consuming metod of acualizing List in TListBox.

   And the second question? Is there any trick to display long, very long
lists in ListBox and not keep the whole list in memory. In the case of
approximately 1000 elements of 200B size, it is 200 KB. (and internal
SortedCollection allocations for each element).

Thanks in advance
