Dienst starten mit Delphi

[krac]

Hallo zusammen,

ich hätte eine frage zu diesem code :

Delphi-Quellcode:

function ServiceStart(Machine, ServiceName: string): Boolean; 
// Machine is UNC path or local machine if empty 
var 
  h_manager, h_svc: SC_Handle; 
  ServiceStatus: TServiceStatus; 
  dwCheckPoint: DWORD; 
  ServiceArgVectors: PChar; 
begin 
  h_manager := OpenSCManager(PChar(Machine), nil, SC_MANAGER_CONNECT); 
  if h_manager > 0 then 
  begin 
    h_svc := OpenService(h_manager, PChar(ServiceName), 
      SERVICE_START or SERVICE_QUERY_STATUS or SC_MANAGER_ALL_ACCESS); 
    if h_svc > 0 then  //ab hier bricht er ab und beendet alles 
    begin 
      if (StartService(h_svc, 0, ServiceArgVectors)) then { succeeded } 
      begin 
        if (QueryServiceStatus(h_svc, ServiceStatus)) then 
        begin 
          while (SERVICE_RUNNING <> ServiceStatus.dwCurrentState) do 
          begin 
            dwCheckPoint := ServiceStatus.dwCheckPoint; 
            Sleep(ServiceStatus.dwWaitHint); 
            if (not QueryServiceStatus(h_svc, ServiceStatus)) then 
              // couldn't check status 
              break; 
            if (ServiceStatus.dwCheckPoint < dwCheckPoint) then 
              break; 
          end; 
        end; 
      end; 
      CloseServiceHandle(h_svc); 
    end; 
    CloseServiceHandle(h_manager); 
  end; 

  Result := (SERVICE_RUNNING = ServiceStatus.dwCurrentState); 
end;

und zwar wenn ich dies ausführe, komme ich nie in die ab kommentar rein

könnt ihr mir lösungvorschläge geben

danke im vorraus
