Hi
Is it possible to change the appearance/color of certain items inside a
listbox? To indicate if some items are active.

Example

Listbox:
Item1
Item2
Item3
item4 --- This are all the possible values

When compared this values with a query, let's say that item3 is
missing, So item3 is showed in the listbox, but can't be selected.

Regards,
LCK
