dOPCAE.TdOPCEventServer.OnEvent

OnEvent is generated when the server receives a new event notification.

Delphi

property OnEvent: TOndOPCEvent;

C++

__property TOndOPCEvent OnEvent;

Remarks

This event is only meant for logging affairs or if you don't want to use the Events collection. It is recommended to use the OnEndUpdate event to show received event notifications.

Copy Code

procedure TForm1.dOPCEventServer1Event(Sender: TObject; Event: TdOPCEvent); begin Memo1.Lines.Insert(0,(format('%s %s (%s)', [DateTimetoStr(Event.Time),Event.Msg,Event.Source]))); end;
