Hi,

I'm a pascal newbie, after spending some time getting a daemon to work, I now have trouble getting a timer to work. I was recommended to use TFPTimer from the fpTimer unit - http://mantis.freepascal.org/view.php?id=14118&nbn=5

I tried the following code but the OnTimer doesn't trigger. There are no errors either. Grateful for any pointers. :)

uses
fpTimer;
...
 TDaemon1 = class(TDaemon)
....
private
.....
public
    procedure FTimerTimer( Sender : TObject );
.....
var
  Daemon1: TDaemon1;
  FTimer : TFPTimer;
.....
procedure TDaemon1.FTimerTimer( Sender : TObject );
var
...
 BEGIN
....
END;
procedure TDaemon1.DataModuleStart(Sender: TCustomDaemon; var OK: boolean);
var
...
begin
 FTimer := TFPTimer.Create(nil);
 FTimer.OnTimer := @FTimerTimer;
 FTimer.Interval := 1000; // in milliseconds
 FTimer.Enabled := True;
 FTimer.StartTimer;

Note: I've also posted here - http://lazarus.freepascal.org/index.php/topic,8615.0.html

The standard driver for fpTimer is not suitable for use in a daemon application, as the timer events are only triggered in the main thread, and each daemon runs in its own thread.

Hi Michael, thanks, is there a work around solution to simulating a trigger in a Lazdaemon?

Rgds,
Joshua

Michael.

the problem is, that a normal thread does not have a message queue. You can create a second thread, which calls some method in a periodic cycle and sleeps in between. But you must take care, that this thread is synchronized to your daemon thread.
