The main difference between a VBA ComboBox and a ListBox in VBA lies in their appearance and behavior: • ComboBox: A ComboBox is a control that combines a text box with a drop-down list. Users can either select an item from the list or enter a custom value by typing in the text box. It allows for both selection and input. • ListBox: A ListBox, on the other hand, is a control that displays a list of items. Users can select one or more items from the list by clicking on them. It is primarily used for displaying a list of options for selection.
