Ken,

You can also set the ListIndex property if you know what row you want. What is the scope of your a_tmp array? It probably should be either a property of your cbo class or of the form.

>Specifically, a_tmp is a two-dimensional array containing codes and descriptions. It is the RowSource of my combobox. The button.click event code below works fine to display the description for 'COD1' in the combobox. However, when I then try to select by picking from the dropdown list, I get 'feature not available' error.
