Create An Array Of Timer - Raise The Tick Event For A Particular Timer?
Jan 11, 2011I want to create an array of timer in vb.net. My problem is that how will i raise the tick event for a particular timer, say mytimer(x).tick and inside the tick event there is also a button, say mybutton(x) which changes location every interval. for example:
public class blah
dim mybuttons(20) as button
dim mytimer(20) as timer
private sub form_load(....) handles me.load
for x as integer = 0 to 20
[Code]...
i dont know what to do next, all i want is to pass the button mybuttons(x) to mytimer(x) tick event, in which their index number are the same. i want to create one timer per button. how to do that? please help me and post example codes. i've researched the net but i cant understand passing variables, addhandlers, etc. i'm just new to programming object oriented.

View 4 RepliesCreate A 15 Warning Before Timer Even?
Oct 6, 2010I have an app with a timer control, and the interval is set to 60000ms (1 min). so every min i have some event happen. thats pretty simple. however, i want to have a 15 second warning that the event is going to happen. so basically 45 seconds after my timer starts, i want a message such as "15 seconds left until event x happens".
would i have to use 2 timers? i guess im lost on the logic. i know how to use the timer control, but i have been googling all night trying to figure this one out. i have tried using 1 timer set to 45 seconds (for the warning) and another timer at 60 seconds(for the event) but they go out of synch after 1 iteration and will not consistently stay 15 seconds ahead of the other. i dont want to post any code i have, because it is all trash and i want to start over from scratch.

Trying To Create A 24-hour Timer
Jun 9, 2010How 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???
View 6 RepliesUsing A Timer To Create A Delay?
Oct 15, 2009I'm using Visual Basic 2008 Express Edition.I'm working on a class. At various points, I want to insert a delay between executions of the code. Nothing terribly large. Around 50-200 miliseconds. It doesn't seem like much, but it makes the program run better. I'll probably randomize the length of the delay later between those two marks. So basically the code would go...SomeFunction()timer delaySomeFuntion()I have the timer declared as
Private tmrTimer As TimerAnd each place I want to use it, I simply redeclare it. Or I might add it to the constructor of the class. Either way. Just thinking adding it to the class constructor would probably be a better idea.

End SubUnfortunately, I get the error "Handles clause requires a WithEvents variable defined in the containing type or one of its base types"Now remember, this is all contained in a class, so theoretically speaking I can simply move the class file from project to project and reuse it, without ever having to worry about how the class works. Reading through the Timer specifications, I probably need to do some cleanup on the timer after I use it. Am I correct in this?

May 16, 2012I want to create a timer while the application is running. For example, the form has TextBox1 and Button1. When Button1 is clicked, the timer will be enabled and will print the current system time in TextBox1 every 10 seconds. The timer will be disabled when the Button1 is clicked again. How do I implement the timer and its events? An example with both Windows Forms and Silverlight would be great.
View 7 RepliesCreate A Timer That Will Activate A Tick Event?
Jul 11, 2011I am attempting to create a timer that will activate a tick event every 1 second until stopped by an "If" statement. The tick event should then drive a clock measuring time in units of hours, minutes and seconds. The if statements handle the time readout, timer stop and activate another form after a set number of hours have elapsed. I have tried several different methods and while my application is running, it does not add increments to the integers representing the time units, refresh the displayed time units, or perform any of the timer related functions. I assume the cause is that I just don't know as much as I think I do (which isn't much)
Here is the applicable code:

Create A Timer To Execute On A Separate Thread?
Jan 23, 2012Currently I'm creating a task that runs a hardware i/o loop for the duration of my program.i.e. it's a task that's created at the program's start and runs a loop that is only broken at the programs termination. Each loop cycle communicates via ethernet to hardware.depending on time outs each cycle takes 30-300 msec)I've noticed that if the loop runs with out any break that the program really slows down... to counter act that I placed a thread.sleep(x) in the loop

Oct 21, 2010I 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.

View 6 Replies.net - Accurate Windows Timer - System.Timers.Timer() Is Limited To 15 Msec
Jan 15, 2009I 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)
Jul 9, 2009I 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, 2009I 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?
