>I want to present a listbox and have the focus(highlighted) on a certain record. However I want that record to appear in the middle of the listbox. For some reason it appears at the bottom of the visible listbox by default.

If it is the very last record, or the very first record, then how it may appear in the middle?
In any case, in your code you may call keyboard with appropriate keystrokes to achieve what you need.
