Timothy,
What you're talking about is what is often called a "Quicken-style" combo after the accounting program that used this type of combobox. If you search under 'Quicken' you should find several in Files.

However I am more concerned with your putting 500 records into a combobox. Combos and Lists get unstable after about 200 records, and will become slow to load and slow to react to user entry. You might consider building a textbox/button/grid combination which handles the data much faster. Let the user enter data into the textbox,using the InterActiveChange() to search for the 'next match'. Then if they want to see a list use the button to pop up a grid (visible = .T.) with the closest record showing.

The problem with 500 records is that later they're 600, then 1000 and you have users screaming about speed.
