How to get address from all open IE windows

I have a code to get only the first/active IE window url address (from delphi3000): function Get_URL(Servicio: string): String;
var
Cliente_DDE: TDDEClientConv;
tempChar;
begin
Result := '';
Cliente_DDE:= TDDEClientConv.Create( nil );
with Cliente_DDE do
begin
SetLink( Servicio,'WWW_GetWindowInfo');
temp := RequestData('0xFFFFFFFF');
Result := StrPas(temp);
StrDispose(temp);
CloseLink;
end;
Cliente_DDE.Free;
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
Edit1.Text := Get_URL('IExplore');
end;
-----------------------------------------------------
I tried to "play" with the code a bit...
it seems to work if i change temp := RequestData('0xFFFFFFFF') to:
temp := RequestData('1'); //1 window
or
temp := RequestData('2'); //2 window
or
temp := RequestData('3'); //3 window
and so on... until temp returns '' (empty string)
Anyway, try it.
