Timer event doesn't get fired

[eljainc]

Hello,

I'm having a problem with a simple application that I've written. I
have a form that loads another form. The second form has a timer
control on it. The timer will not fire for some reason. I have it
enabled and also used the start method. What might the problem be?

I've tried System.Windows. Forms.Timers and System.Timers but no luck.

Any help appreciated

Mike

It's hard to say what's wrong with no code. Could you post a short but
complete program which demonstrates the problem?

See http://pobox.com/~skeet/csharp/complete.html for what I mean by
that.

Re: Timer event doesn't get fired

Is this a windows application? Starts like:

Application.Run (new Form1());

or is this a Console application, if its a console application I don't
think the System.Windows. Forms.Timers will work, I think you will need
the:

System.Timers.T imer

Re: Timer event doesn't get fired

Err... actually never mind.

but I think you may have problems if you run a timer that inherits
from Component on a console application or Windows server.... not
sure... time to do some research!

Re: Timer event doesn't get fired

It seems that when I use the command

Thread.Sleep(xx )

in my code in the units that use the timers, this is when the problems
occur. I will need an alternate
to the Thread.Sleep() method. Is there anything else out there that
is similar?

I don't think you fully know how to use a spawned child thread that runs on
the Thread.Sleep method. I have never ever had a problem with the technology
with the execution of logic on a child thread on a timed basis.

Maybe, you should just drag a Timer control out of the Toolbox used for a
Windows Desktop form solution, place it on the form and use that Timer
control.

That's what I did. I used a designTime Timer control from the
toolbox.

The problem that occurs I found is when I mix the timer component with
the
System.Diagnost ics.Stopwatch control. I would like to have multiple
timers
activated, but some timers I would like to use the .Elapsed property
of Stopwatch
so that I know how much time has passed instead of having an event
fire every xx
seconds or xx milliseconds.

Is there a Stopwatch replacement that will not cause conflicts with
the timer component?

Thanks

I don't know. I have never used the Stopwatch. Maybe, you should just use a
Timer control in the Toolbox for form controls using the Tick event of the
Timer with the Stopwatch. Maybe, that will work for you.

As Jon said, until you post a complete code sample, there's no good way to
answer your question.

That said: I guarantee you that using the Stopwatch class is not causing
your issues. It simply measures passage of time. It doesn't delay
threads or cause other problems.

What _is_ a problem is calling Thread.Sleep() from a GUI thread, and given
that you seem to be using the System.Forms.Ti mer class, you are most
likely calling Thread.Sleep() from a GUI thread. If the GUI thread is
sleeping, the timer can't fire.

Of course, this is all speculation. Since you haven't posted a complete
code sample, there's really no way to know what's wrong with your code.
