Thanks

hello ,

I have same problem.

any one can help me ???

I am having the same problem sam, can you please email me on grant.thomson@savante.co.uk

I have been writing a windows application using forms; have tried both system.timers.timer and forms.timer and both seem to fail.  

Do you think going to threading.timer is the silver bullet here?

i have created a project and  web service to it.... the service which is i created it use the exe file of the project. but service is not running..

Could some please explain how to switch from a system.windows.form.timer  to a System.Threading.Timer

Sorry for posting again. I have been trawling the internet trying to find a meaningful example of System.Threading.Timer in plain english.

I am beginning to think that it doesn't.

I am trying to do something easy (so I thought). I want a service to write to a text file every  minute in VB.net 2005, it doesn't appear possible.

If you could provide something simple to do this, I would be very grateful.

Nice one! Thanks a lot, this helped me out BIGTIME!

The funny thing is System.Timers.Timer uses System.Threading.Timer internally ( can be found through Reflector). So its a wrapper around Threading.Timer  and microsoft tried to do some fancy things around the wrapper having some bugs in it. So its advised to use Threading.Timer.

There seems to be a similar problem with System.Windows.Forms.Timer not firing. I found if I called Stop() and Start() to frequently it would stop firing at all. Using System.Threading.Timer fixed the problem even though it is a forms based application

Hello all

I am using system.timer bt it is not working properly

So i have decided to switch to system.threading.timers

Please someone tell me how to switch from system.timer to system.threading.timer

By the way, I just wanted to point out that I was able to reproduce the dead timer issue on a VM server 2003 w/ SP1 which had .NET 2.0 Framework--it appears this issue is not isolated to JUST the 1.1 Framework

DDJames - To switch from system.timer to system.threading.timer; go into the Designer file and manually modify all instances of the times. So if the file that has the time is Service.vb, go to the Service.Designer.vb file and modify it. Hope that helps.

I am trying the examples posted on vbcity.com/.../topic.asp

private System.Timers.Timer MyTimer;

        protected override void OnStart(string[] args)

       {

           // Interval in milliseconds

           double interval = Properties.Settings.Default.TimeDelay * 60000;

           // Create timer object

           myTimer = new System.Timers.Timer(interval);

           // Set to run more than once

           timer.AutoReset = true;

           // Delegate to handle the timer event

           timer.Elapsed += new ElapsedEventHandler(timer_Elapsed);

           // Start the timer

           timer.Start();

           // Prevents garbage collection from occuring in long running methods

           GC.KeepAlive(timer);

       }

       private void timer_Elapsed(object sender, ElapsedEventArgs e)

       {

             try

             {

                     myTimer.Stop();

                      // Place call here to execute code

              }

              finally

             {

                     myTimer.Start();

              }

        }

He states that the timer stops running due to garbage collection and that every time the timer is stopped it is subjet to garbage collection. I don't know if this is the final solution but this is where I am with the process

This explains the issue

The URLs at the start of the post all appear to be dead. Please update them if possible.

Here's a great article that will help you understand Timers in Windows:

Does the same effect for Visual Studio 2008 as well?

I am able to reproduce this in VS 2008 as well.

Can someone help me with system.threading.. The above links are broken.. Any sample code?
