Well. Yes, this is be possible, but it has some minor quirks:
- If the edit is on a small dialog the listbox is also very short.
- A listbox needs all items in advance for its scrollbar. This would  
be pretty slow if the completion box shows thousands of files/words.
- for the highlighting/formatting we need to custom paint.
IMO a custom control is better suited.

Is there any volunteer to program a TCompletionBox?
