Timer in Console application

[Aart Nicolai]

Hi all,

I have developed a vb.net console application which will run some code
every [x] seconds. To get this working I used a timer "System.Timers" .
When I start my console application it exits within a second. So I
added the line: "Console.Read() ". Everything seemes to run fine but
after a few days the application stopped. Without an error.
I think it has something to do with the lifetime of the
"Console.Read() ". Is this right?

Is there another trick to solve this timer problem?

Thanks,

Aart

Re: Timer in Console application

I forgot to add the code.
<cut>
Dim TimerInterval As Integer = m_Settings.GetV alue("TimerInte rval",
GetType(String) )
AddHandler aTimer.Elapsed, AddressOf OnTimedEvent
aTimer.Interval = TimerInterval
aTimer.Enabled = True
aTimer.AutoRese t = True
Console.WriteLi ne("Wacht op aflopen timer [" &
m_Settings.GetV alue("TimerInte rval", GetType(Integer )) / 1000 & "
sec.]")
Console.Read()
</cut>

Re: Timer in Console application

why not just replace with an infinite loop with a sleep in?

Re: Timer in Console application

or better still, using the threading class'es timer within your loop

ie
do
threading.threa ding.sleep(5000 ) ' sleep for 5 seconds

' Do your stuff here

loop until false ' I think you can use this for an infinite loop

Re: Timer in Console application

Aart,
Rather then use a Console application, have you considered a Windows Service
application?

As a Windows Service are designed to run "forever", plus they can be started
when the machine starts, rather then require someone to log in.

If your app "needs" to be a Console application, as the others suggests, you
need to prevent your Main from exiting. I would probably use a Mutex,
AutoResetEvent, or ManualResetEven t (favoring the reset events over the
mutex) to keep it from exiting. This way the timer thread can have the main
thread exit if the timer thread decides its "done". By timer thread I mean
the thread where the System.Timers.T imer Elapsed event is raised...

Post if you want help with the reset events or the windows service.

Re: Timer in Console application

Thanks, I think I will transform it into a windows service..
