How to get a list of Local Ip Address

I noticed that when i use the Indy Component IdTCPServer, when i click bindings, there is a combo box with a list of local Ip Addresses.  How would I go about getting that list?

If you still use tIdTCPServer it's simple....

Just add IDSTack to the uses clause and us the GStack.LocalAddresses list

A little sample:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs,  StdCtrls, IdBaseComponent, IdComponent, IdTCPServer,idstack;

type
  TForm1 = class(TForm)
    Button1: TButton;
    ComboBox1: TComboBox;
    IdTCPServer1: TIdTCPServer;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
combobox1.Items := GStack.LocalAddresses;
combobox1.Items.Insert(0,'127.0.0.1');
end;

end.

Thanks, that should help other people on EE with the same question.  (Funny I didn't find a question like it on EE).  I was looking for the INDY approach, but its good to know there is more then 1 answer.

Glad to have helped you :)

BTW a suggestion for your next Indy needs: in program files\borland\delphiX\source\indy there are the indy source files...
sometimes seems to be hard to find Indy solutions even by googling or surfing the Indy project Web site too, so the best way is to find solutions looking directly the source code....
