I dont have Delphi in front of me but here goes:
Type //where the objects etc are declared in your unit
tRossesObject = Class(TObject)
FieldOne : Integer;
FieldTwo : String
...
end;
So you now have the template for an object.
Now, in the loop you populate your Listbox, or each time you add an item you
want to:
Var
myObject : TRossObject;
Begin
myObject := TRossesObject.Create;
myObject.FieldOne := 1;
myObject.FieldTwo := 'Two';
With ListBox1 do
AddObject('Somestring to display', myObject);
myObject.Free; //the list owns a reference to it now
end;
The flip side is retrieving the object which can be accessed (wish I had the
IDE now) through the ListBoxes Objects collection (ie something like):
myObject := Listbox1.Objects[ListBox1.Listindex];
TextBox1.text = InttoStr(myObject.field1);
Please excuse the liberal and no doubt offensive to some VB 'ness of some of
the above. Hopefully enough to get you going though.
Call me in the weekend if you want a hand.

The Delphi book I have doesn't explain this item object linking very well at
all. I
presume I create an object as needed when a new item is added to the list.
How do I
do that considering I have to give each object a name? A small example
would be
appreciated.
Thanks,
Ross.
