Timer To Run 30 Minutes After The Hour?

Jul 15, 2010

Is it possible to configure the System.Timer to run say 30 minutes after every hour? I have searched google to figure this out but all it shows is how to set it where it goes off once an hour, if I launched the app at 2:45 then it would go off again at 3:45. I can forsee issues down the line with this approach where if it went off at a specified time it would not have that issue.

Normally i would use Scheduled Task for this however it doesn't give you the option for hourly just daily, perhaps i'm wrong about this.

Windows - Timer - Service To Execute On The Half Hour And Top Of The Hour Marks

May 6, 2009

I wrote a VB.NET Windows Service, which works fine. I have only one issue with it. I want the service to execute on the half hour and top of the hour marks (e.g. 9:00, 9:30, 10:00, 10:30, 11:00, etc etc etc). I am using the following code:

Protected Overrides Sub OnStart(ByVal args() As String)
' Add code here to start your service. This method should set things
' in motion so your service can do its work.

[CODE]...

This code works, however, if the service starts at, say, 10:15, then it executes at 10:15, 10:45, 11:15, 11:45. How do I make it so it always executes on the 30 minute and top of the hour marks?

Trying To Create A 24-hour Timer

Jun 9, 2010

How would I go about creating a Timer that will fire an Event every 24 hours, 2 minutes? I know the Interval in ms is 86,420,000, but of course the Timer Interval will not go that high. Do I have to have a series of Timers to go off every minute until 24 hours is reached???

Console App Timer To Call Web Methods Every X Minutes?

Dec 22, 2010

I am coding in VB.Net, VS 2008. I wrote a console app that consumes 2 web methods from a web site application. I need to enhance this console app so that it launches the web methods continuously, perhaps every x minutes (during business hours), but never before the last invocation has terminated, whose duration may vary, depending on how many accounts there are to process.

Originally, I scheduled the application using Task Scheduler, but I think this doesn't prevent two invocations at the same time.

Although I have seen many posts on using timers, I haven't found exactly what I need.

So far I have:

Dim aTimer As New System.Timers.Timer()
AddHandler aTimer.Elapsed, AddressOf TriggerWebMethods
' Set the Interval to 10 minutes:

[Code]....

When should Timer.Elapsed be used vs. Timer.Tick? What is the difference between Timer.Enabled vs Timer.Start, and should I be selecting just one? I would like the 2nd web method to kick off when the first one is done.

Create A Simple Timer To Count Seconds, Minutes And Hours

Oct 21, 2010

I have three sets of labels, lbl_seconds, lbl_minutes and lbl_hours. These labels have the default value of 00:00 and I want the timer to change that for each label. I have googled this but I cannot seem to find any good info on it. Do I need three separate timers? I have also noticed that the timers have their own tick event handler. I guess it's in this that I need to change the value of the label. But I cannot figure out how to do just that.

SetLastWriteTime Is Off By 1 Hour?

Jan 16, 2009

I've written a console utility to set file date/time stamps to a specified date/time:

For Each FoundFile In My.Computer.FileSystem.GetFiles(FileSpecPath, FileIO.SearchOption.SearchTopLevelOnly, WildCards) FileInfo = My.Computer.FileSystem.GetFileInfo(FoundFile) System.IO.File.SetCreationTime(FileInfo.FullName, NewDate) System.IO.File.SetLastWriteTime(FileInfo.FullName, NewDate) System.IO.File.SetLastAccessTime(FileInfo.FullName, NewDate) Console.Write(FileInfo.Name + " " + NewDate)Next

When I go to a command prompt to check the results, the new date is correct, but the hour is off by 1 hour. Same when I check the times in Windows Explorer -- all three times are displayed to the same time, but exactly 1 hour earlier.The system date/time are correct (Vista) and we are not in DST.The files reside on a local drive (not a network share).The computer is not on a domain.

.net - Accurate Windows Timer - System.Timers.Timer() Is Limited To 15 Msec

Jan 15, 2009

I need an accurate timer to interface a Windows application to a piece of lab equipment.I used System.Timers.Timer() to create a timer that ticks every 10 msec, but this clock runs slow. For example 1000 ticks with an interval of 10 msec should take 10 wall-clock seconds, but it actually takes more like 20 wall-clock sec (on my PC). I am guessing this is because System.Timers.Timer() is an interval timer that is reset every time it elapses. Since it will always take some time between when the timer elapses and when it is reset (to another 10msec) the clock will run slow. This probably fine if the interval is large (seconds or minutes) but unacceptable for very short intervals.Is there a function on Windows that will trigger a procedure every time the system clock crosses a 10 msec (or whatever) boundary?

UPDATE: System.Timers.Timer() is extremely inaccurate for small intervals.I wrote a simple program that counted 10 seconds several ways:

Interval=1, Count=10000, Run time = 160 sec, msec per interval=16
Interval=10, Count=1000, Run time = 16 sec, msec per interval=15
Interval=100, Count=100, Run time = 11 sec, msec per interval=110
Interval=1000, Count=10, Run time = 10 sec, msec per interval=1000

It seems like System.Timers.Timer() cannot tick faster that about 15 msec, regardless of the interval setting.Note that none of these tests seemed to use any measurable CPU time, so the limit is not the CPU, just a .net limitation (bug?)For now I think I can live with an inaccurate timer that triggers a routine every 15 msec or so and the routine gets an accurate system time. Kinda strange, but...I also found a shareware product ZylTimer.NET that claims to be a much more accurate .net timer (resolution of 1-2 msec). This may be what I need. If there is one product there are likely others.

Asp.net - Local Static Variables In Timer.Tick Event (Stopping A Timer)

I have a timer on a page in ASP.NET.

After a certain period of time elapses, I want to disable the timer.

I want to put a static variable in the timers tick event that will track how many seconds have elapsed.

My question is, will this work?

If user X and Y are viewing the page will they both have separate local static variables?

What is the best method of shutting down an ASP.NET timer after a certain elapsed time?

Synchronize The Timer Event So That The Timer Executes From The Background Worker Thread?

Apr 23, 2009

I have a windows application that need to process som quite time consuming jobs. In my first try i did all processing under
the form thread. The result was bad response and update of the form due to the heavy jobs.To get around the problem with bad response from the form i created a new class "processing" where i put all the data processing. Then i instanciated a background worker where i in the "doWork" sub created a new instance of "processing".The "processing" class creates a timer from system.timer, and the timer drives the processing.On the Timer event Elapsed the timer starts a new thread from the thread pool.

My problem is now when i want to asynchronously close the background worker (with the corresponding function call what ever it is called ...) there is still a timer thread out there that causes exceptions for me.

1. How can i close my background worker and at the same time have the timer to be stopped?

2. Is there a way to synchronize the timer event so that the timer executes from the background worker thread?

3. Is there a better approach for me to adapt?
