Dan,

I may be missing something, here, but if all you want to do is highlight a particular item in the list, then after you create the array and requery() to update the list, set ListItemID to the number of the item you want to select.

WITH thisform.myCombobox
     * Add the array rowsource
     .AddProperty( "aRowSource[ 2 ]" )

     * Populate the array
     .aRowSource[ 1 ] = "Yes"
     .aRowSource[ 2 ] = "No"

     * Populate the list from the array.
     .Requery()

     .ListItemID = 2 --> "No" is highlighted and selected.

ENDWITH

Regards,
