I have a dbcombobox with a items list of authors. If the text the user enters is not an author already in the combobox list I want to be able to add it to the list (without getting multiple entries for the same author).

Hi!
Pls, Say what you really need:
1) The procedure which compares New Author and all other Autors before Post an Author or
2) the same but while the user types smth in the box?

Easiest way (case insensitive):

AlreadyThere := (ComboBox.Items.IndexOf(NewEntry)<>-1);
if not AlreadyThere then begin
  ComboBox.Items.Add(NewEntry)
end;
