So I am trying to add a TListBox to my program. Relevant code is below.

   TfrmFicMake = class(TForm)
     .
     .
     .
     lstVolumeList: TListBox;
     .
     .
     .
   end;
procedure TfrmFicMake.btnAddVolumeClick(Sender: TObject);
var
   index : integer;
begin
   frmCreateVolume.ShowModal;
   lstVolumeList.Clear;
   for index := 0 to (Length (Volumes) - 1) do
       lstVolumeList.AddItem (Volumes [index].VolumeName);
end;

When I try to compile this, I get:

mainform.pas(55,18) Error: identifier idents no member "AddItem"

Now, I am almost certain, based on having perused the documentation, that TListBox contains a method called AddItem. What am I doing wrong?

Further update: TListBox and TCustomListBox do not, in their source code, list any AddItem method. The documentation states that TCustomListBox is the earliest ancestor with the AddItem method.

The AddItem method takes two parameters, a string and an associated TObject. If you only want to use the listbox to store a list of string items use

   lstVolumeList.Items.Add(Volumes[index].VolumeName);

just
ListBox1.Items.Add('myString)');

Thanks for the help. In retrospect, the error I made was obvious. :(
