System.Timers.T imer

Hi there,

I have three methods these need to execute at every interval time. I
would like to know which option is better?

Option A)
Three System.Timers.T imer objects these execute each method.

timer1.Elapsed += new
System.Timers.E lapsedEventHand ler(Method1_Ela psed);
timer2.Elapsed += new
System.Timers.E lapsedEventHand ler(Method2_Ela psed);
timer3.Elapsed += new
System.Timers.E lapsedEventHand ler(Method3_Ela psed);

Option B)
One System.Timers.T imer object that execute all methods.
timer1.Elapsed += new
System.Timers.E lapsedEventHand ler(Method1_Ela psed);
timer1.Elapsed += new
System.Timers.E lapsedEventHand ler(Method2_Ela psed);
timer1.Elapsed += new
System.Timers.E lapsedEventHand ler(Method3_Ela psed);

Do you want the methods to execute in parallel, or in series? If you
don't mind them executing in series, I'd use the second version.

How come the eventhandler for the timer's elapsed time event is called over and over again, even though the AutoReset property is set to false, if you assign a new value to the timer objects interval property inside the event handler? Example follows: Constructor: mTimer = new System.Timers.Timer(20000); mTimer.AutoReset = false;

Hi, I've seen several articles about using System Timers in ASP.NET solutions, specifically setting them up in Global.asax' Application_OnStart event. I'm thinking about the scenario where I might need to carry out some back-end processing without pausing the individual users' Session while that process runs. E.g. I might provide the ability for a user to upload a text file of job

Help! I am new to Visual Basic .Net (version 2002) and I am trying to get a System.Timers.Timer to work for me to display a splash screen for about two seconds and then load the main form. I have two forms (frmSplash and frmMain) and a code Module setup as my startup object. Here is the code that I have, when I try to run this part of the splash screen form shows and then program terminates. What am I doing wrong? Thanks,

Hi all, I set up a System.Timers.Time in my app. The code basically just updates the screen, but since the processing performed is so CPU-intensive, I wanted to make sure it gets updated regularly; like every 1.5 secs. or so. I only ran into one issue - the MyTimer_Elapsed event handler was not updating the screen correctly all the time, often leaving large chunks of the screen un-painted for several seconds. On a whim I decided to...

Hi, I'm have a datagrid, and I'm trying to have a tooltip pop up if a cell has been hovered on for 2 seconds. I was thinking of using DataGrid.Hover, but then decided to try this instead: static System.Windows.Forms.Timer timer = new System.Windows.Forms.Timer(); private void dg_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e) { System.Timers.Timer timer = new System.Timers.Timer();

All, I have a Windows Service and it has one System.Timers.Timer that fires every 500 milliseconds. Now I have noticed that there's a bug in System.Timers.Timer when it's being used combined with Windows Service. That is, the Timer won't fire again once it's stopped (Timer.Stop() or Timer.Enabled = False) (http://support.microsoft.com/kb/842793/en-us). Instead of using Threading.Timer, can I just have the code to run inside the...

I have a windows application written using VB .NET that encompasses a countdown timer modal dialog. The timer is a System.Timers.Timer with an interval of 1 second. AutoReset is not set so accepts the default of True. The Elapsed event handler updates the dialog box with how long before it will close, acting as a timer itself. The dialog has a time to close property which is checked every time the Elapsed event fires. The problem I have...

I have a class that instantiates two Timer objects that fire at different intervals. My class can be instantiated within a Windows Form or from a Windows Service. Actions performed by one of the event handlers may take longer than the interval for either of the timers, so it's possible for multiple events to fire "simultaneously" and for events to queue up. I'm attempting to get the timers to sync on some reference type object, or use...

I'll greatly appreciate any help on this. Actually 2 questions: 1. I believe I need to use the Windows timer System.Timers.Timer . The examples I find on the web all access that timer by 'import System' . (That's System with a capital S.) I have pywin32 installed and 'import System' doesn't find System so I gather it's not in that package. Where does one get the package with Windows' System class? 2. The reason I've been...

I'm looking into a production issue related to a windows service and System.Timers.Timer. The background is the windows service uses a System.Timers.Timer to periodically poll a directory location on a network for files and then copies these files to another location (on the network) AND then updates a record in the database. The file copying is performed before the database update because the file system is not transactional. The code...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
