Fudging it by inserting a first line with the captions programmatically and forbidding to select them should be achievable with adding items programatically, but if list is long, first line would be srcolled out and therefore invisible - Or use collection or array as rowsource. Depends on the customer if such a half-hearted "caption" is seen as a benefit or distraction ;-)

But if customer is adamant and willing to pay, drop them a direct question.

>>I will check the resources you mentioned. Thank you. I also consider changing the combobo with the look-up control that uses a form with the entries, instead of the drop box. In such form, captions would be easy since I would use a grid control. My concern was that instantiating a form could take time but with the speed of PCs, it probably won't be noticeable.

I don't use VisualExtend and I have done tons of the form-grid-based lookups. So it should not be a problem to make one more.
