My trouble is in C++ Builder but if you tell me something about Delphi Im vey grateful.

Well, I wish associate each item of a ComboBox (Client Name)  with another text (Client Code), I think that i must do it with the method AddObject from Items, its prototipe is AddOboject(AnsiString,TObject), the code is

void __fastcall TForm1::Button1Click(TObject *Sender)
{
    AnsiString SQLText;
    int indice;

    SQLText = "SELECT * FROM CLIENTES WHERE     NOMBRE LIKE '";
    SQLText = SQLText + ComboBox1->Text + "%'";
    Query1->SQL->Text = SQLText;
    Query1->Active = true;
    if (!Query1->Eof)
    {
      while (!Query1->Eof)
        {
        indice =   ComboBox1->Items->AddObject(Query1->FieldByName("N         OMBRE")->AsString
        ,Query1->FieldByName("CODIGO"));
        Query1->Next();
        }
    }
    Query1->Active = false;
}

Both ClientName, as CodeClient are on a database, as you see i associate the clientname(first parameter) with a TField Object, my trouble is that ...indice is ever the same!! ( indice ever has value equal to one, two...) and when i want retrieve from my Form. just stand the last item :((.

Thank you

Of course "indice" always has the same value after the while-loop (at least as long as the database contents is constant).
I really do not understand what the "indice" variable does in your code, unless you want to find the index of the last item in the combobox.
If you want the "object" associated with an item in the combobox, you just do:

var
  MyObject: TObject;
// TObject MyObject;
     ...
  MyObject := Combo1.Items.Objects[ iIndex ];
//  MyObject = Combo1->Items->Objects[ iIndex ];
  if Assigned( MyObject ) then ...
//  if ( MyObject != NULL ) { ...

Probably not the answer for your question, but...
