Bonjour,
On me demande de développer un service, qui vise à logguer l'extinction d'un ordinateur.
Mon problème provient de cette action "sous win2000, quand l'utilisateur appuie sur le bouton power (marche\arret) du pc, celui ci s'éteint dessuite.
Or je n'arrive pas à logguer cette action.
Voici mon code :
[Code]
unit Unit1;
interface
uses
Windows
, Messages
, SysUtils
, Classes
, Controls
, SvcMgr // TService
;
type
TSrvUpTime = class(TService)
procedure ServiceCreate(Sender: TObject);
procedure ServiceDestroy(Sender: TObject);
procedure ServiceShutdown(Sender: TService);
procedure ServiceStart(Sender: TService; var Started: Boolean);
procedure ServiceStop(Sender: TService; var Stopped: Boolean);
procedure ServiceContinue(Sender: TService; var Continued: Boolean);
private
{ Déclarations privées }
LogHandle : THandle;
Procedure WMEndSession(var Msg : TWMEndSession); message WM_ENDSESSION;
procedure WMPowerBroadcast(var Msg: TMessage); message WM_POWERBROADCAST;
public
function GetServiceController: TServiceController; override;
{ Déclarations publiques }
end;

Si quelqu'un a une idée, ou des suggestions, ce serait sympa.
Merci d'avance
