I can't understand. Do you need to close your application if NT is about shutting down?

(Tu voulez fermer le programme si NT finit le travail?)
(Du willst das eigene Programm zumachen falls NT die Arbeit beendet?)

fein deutsch ...
folgendes ...
sobald du in delphi die elemente benutzt, NMPOP3 Komponente und die Windowsmessages abfängst (ich leite sie einfach weitermit inherited, nur als beispiel)

fährt NT nicht mehr runter wenn du NT einfach ganz normal beenden willst.
d.h. meine application verhindert den shutdown von NT.

erstelle diese Application mal bei dir unter NT ...
starte die EXE-datei und versuche dann NT zu beenden.
NT bricht den shutdown einfach ab...

ich weis nur nicht wieso..
in meiner eigentlichen application fange ich dort das minimize ab ...

ich weiß einfach nicht warum NT den shutdown abbricht

hello,
if windows wil not shutdown then i sugest to handle WMQueryEndSession to listen when windows wants to close and when windows wants to shutdown it will return a "ok then close" to windows

Regards Barry


type
  TForm1 = class(TForm)
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
   procedure WMQueryEndSession(var Msg: TWMQueryEndSession) ; message WM_QUERYENDSESSION ;
  public
    { Public declarations }
  end;

var
  Form1: TForm1;
  ok_to_close : boolean;

implementation

{$R *.DFM}

procedure TForm1.WMQueryEndSession(var Msg: TWMQueryEndSession);
const
  CAN_SHUTDOWN = 0 ;
  DONT_SHUTDOWN = 1 ;
begin
  inherited ;
  if ok_to_close then {ok_to_close is the global boolean}
  Msg.Result := CAN_SHUTDOWN
  else {if ok_to_close has been set to false then we would get here}
    Msg.Result := DONT_SHUTDOWN ;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
ok_to_close := true;
end;

Man muß nicht NMPoP3.Disconnect benutzen falls du die Verbindung zuerst nicht erledigt hast. Falls du die Version NetMasters 5.3 jenes TForm1.onCloseQuery benutzst

Procedure TForm1. FormCloseQuery (Sender: Tobject; var CanClose: Boolean);
begin
   NMPoP31. Abort;
end;

Hi Barry,
there are bug in TNMPop3. I guess that WMQueryEndSession will never called under NT in this case. I tryed it before.

Die Connection hab ich zwar vorher schon gekillt, rechte aber wohl nicht ...
