Hey Ed! You want to take this one? LOL Sorry Bret, Ed and I have gotten into a number of discussion regarding this.

I have a combobox that uses an array populated from a keyfield in a lookup table. It is a combobox (as opposed to listbox) and it evaluates the entry using a select. If there's a single hit, valid returns .t. If a multiple hit (based on a partial entry) the user is prompted to select from the new result set (i.e. all entries beginning with 's'). Otherwise the user is prompted to add a new record and a form pops up to complete the remaining data in the record.

It works...but....in retrospect, I should have used a SQL statment (cursor) instead of an array. In deference to Ed and some of the others who offered opinions, arrays are a thing of the past where combos are concerned.

If you want to see my code, I'd be happy to email it to you. But using the above scenario with a SQL instead of an array, you'll prob. be able to program something yourself quite nicely. (In either case, the most important properties are Value and DisplayValue and method Refresh)
