Programmatically scrolling a ScrollViewer with a timer becomes jerky
CompositionTarget.Rendering will be a better fit for animating things as it fires every time a frame is about to be rendered. Try something like this instead: public void Shift(ScrollViewer target, double speed = 11, double distance = 20) { double startOffset = target.HorizontalOffset; double destinationOffset = target.HorizontalOffset + distance; if (destinationOffset < 0) { destinationOffset = 0; distance = target.HorizontalOffset; } if (destinationOffset > target.ScrollableWidth) { destinationOffset = target.ScrollableWidth; distance = target.ScrollableWidth - target.HorizontalOffset; } double animationTime = distance / speed; DateTime startTi

System.Timers.Timer Elapsed event executing after timer.Stop() is called
This is well known behavior. System.Timers.Timer internally uses ThreadPool for execution. Runtime will queue the Timer in threadpool. It would have already queued before you have called Stop method. It will fire at the elapsed time. To avoid this happening set Timer.AutoReset to false and start the timer back in the elapsed handler if you need one. Setting AutoReset false makes timer to fire only once, so in order to get timer fired on interval manually start timer again. yourTimer.AutoReset = false; private void Timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { try { // add your logic here } finally { yourTimer.Enabled = true;// or yourTimer.Start(); } }

creating a jquery timer: timer won't continue counting after manual edit

How do I tell that timer in " timer.stop(); " inside onBackPressed() is the same local variable I used before?
Thread.stop() is deprecated and you should not use that. A better Splashscreen implementation would be using Handler-Runnable something like the below. private Handler handler = new Handler(); private Runnable runnable = new Runnable() { public void run(){ Intent openHome = new Intent(Splash.this, main.class); startActivity(openHome); finish(); } } public void onCreate(Bundle b) { super.onCreate(b); handler.postDelayed(runnable, 4400); } public void onBackPressed(){ handler.removeCallbacks(runnable); super.onBackPressed(); }

Is Timer accurate enough to not send TimerEvent.TIMER event after delay?
No, it is not exact. Time slicing is a surprisingly complex process. Here's a few resources: http://www.bit-101.com/blog/?p=910 http://www.craftymind.com/tag/elastic-racetrack/ What it all comes down to in a nut shell, is that the AVM tries to juggle between executing system code, user code and frame rendering as fast as possible, but needs to decide on what process gets which priority (and subsequent processing time) and it's these decisions that will influence timer accuracy. I.e sometimes accurate, sometimes not. Basically, the more you throw at it, the less accurate it gets.

passing timer through dependency injection and configuring / starting a timer
If your question is, that you want to dependency inject a timer that you can later bind an event to, it should be simple. Just create your Timer class to follow an ITimer interface and create methods on it to do the actions you want. public class Calendar { public Calendar(ITimer timer) { // timer is the dependency injected timer timer.SetEvent(EventReminder, 3600); } public void EventReminder() { Console.Write("Hey, it's time for your appointment!"); } } public interface ITimer { void SetEvent(Action callbackMethod, int interval); } In this case, you have a calendar application, and you want your application to have a timer. But you don't care how the timer works, or even what kind of timer (maybe you want a timer that works on mi

Timer kills task/job if it runs longer than timer interval
t.Interval = intervalMiliseconds; That's indeed the troublemaker. It is pretty unintuitive behavior, one that the MSDN article for Timer.Interval specifically warns about in a Note: If Enabled and AutoReset are both set to false, and the timer has previously been enabled, setting the Interval property causes the Elapsed event to be raised once, as if the Enabled property had been set to true. To set the interval without raising the event, you can temporarily set the AutoReset property to true. It's a fairly silly hack but does work. Just delaying assigning the value is certainly the better way to do it. Doing it early doesn't buy you anything, other than trouble, the timer isn't going tick anyway since you've got AutoReset = false. System.Threading.Timer is the better time

I dont understand how to make a timer like apple's countdown timer
You need to keep track of what time was on the timer when you hit back and save it somehow. You can save it through NSUserDefaults which would be the easiest, but since you could have multiple timers it might be cleaner to do a simple CoreData app. The logic (if I understand your problem correctly): 1. User pushes to DetailView and timer starts 2. User wants to pop back 2.1 Save the date the timer started to the task record 3. User wants to go back to same task 3.1 Load the NSDate of when the timer started from disk 3.2 Calculate the offset from then until now 3.3 Add that to the clock 3.4 Start the timer with the offset added Hope that helps.

Python, threading.timer object will not run function timer?
Not sure if this is what you're looking for, but if your problem is that the timer thread is ran independently of the main script, you can join that thread like so: t.start() t.join() # will wait until the thread `t` has finished But this kind of defeats the purpose of running your function in a separate thread. So you might want to just time.sleep for some time before or after sending out that e-mail. By the way, make sure that a call to send_email('Tank temperature Overheat',tank_temp) actually returns a function that will be called when the timer thread is started and doesn't send the actual mail.

How to set a timer like event handler and stop the timer on a condition
The thing I want to do is that I want to do some things AFTER these elements are loaded. In this situation it sounds like you should pass a callback to the function loading the content, which should be executed after the load. If you do decide you want to follow the logic you've mapped out, this should work: var timer = setInterval(function() { if ($(".elementthatmustappear").is(":visible")) { clearInterval(timer); doSomethingElse() } }, 1000);

Can EJB timer invocations overlap for a specified timer according to specification?
The short answer is that I don't think this is specified. The long answer is that I was sure this was specified until I looked through the EJB 3.2 spec and the javax.ejb API doc, and I couldn't find anything that said definitively. The spec is clear that if a single timeout fails that it must retry at least once (which would create a weird scenario where an "old" timeout is retrying after a "new" timeout has succeeded) and that if the container/application is down when a timer should have fired that it needs to fire at least one "catch up", but I couldn't find anything that talked about overlapping timeout methods. I don't know what JBoss does, but for others that find this answer, I do know that WebSphere Application Server implements timeout callbacks for a single Timer in a "serial"

Waiting until a timer runs out and executing another timer
I would suggset working with Tasks. you set up a task to do something (it can just wait for X seconds, than it is a timer) than you set continueWith to assign a new task to run when the first one is finshed. You can read more about this here: http://msdn.microsoft.com/en-us/library/dd537612.aspx And by the way, you really should not run heavy calculations on the UI thread itself. If you decide to use tasks - that would be fine. Otherwise , you need to create background thread and do the work there. Edit: After some clarification from the OP , I will try to explain the basics or working with UI and background threads: When you run a winforms/WPF application, all of the user interface events are handled in a single thread - the UI thread. it goes over all of the events and processes them

How Multiple keypress in Timer or timer altnernative?
Your current code if (Form.ModifierKeys == System.Windows.Forms.Keys.Control && Form.ModifierKeys == System.Windows.Forms.Keys.Enter) means "if the keys pressed equals the control key AND the keys pressed equals the enter key". This will never happen, because if only the control key is pressed, the enter key is not pressed, and vise versa. I believe you wanted this: if (Form.ModifierKeys.HasFlag(Keys.Control) && Form.ModifierKeys.HasFlag(Keys.Enter)) This means "if the keys pressed includes the control key and the enter key". You shouldn't use timers for this anyways. Look into the Control.KeyPress event and use that instead. You can use the timer to load the text file while using events to handle the key press. I suggest you read more about the KeyPress

How to use a thread timer? ASP.NET
For future reference here is an expanded version of my comment. :) The issue was: the code (Javascript) responsible for playing/stopping the music is executed on the client. RegisterClientScriptBlock runs on the server and only generates the above script, so delaying on the server side the second part of the script would only make the client code generation longer without any effect on the way it works on the client. The solution is to implement the delay inside the client code itself, in Javascript. The standard way to mimic a Sleep is using the setTimeout function, so here is the final code: ScriptManager.RegisterClientScriptBlock(Page, GetType(), "sleepTime", "setTimeout(function() {stopSound();}," + Music.GetMusicDuration[i] * 1000 + ");", true);

Timer with new Date() in js
Use setInterval() or setTimeout() to set a timer. But you should notice a subtle difference between these 2 functions due to single threaded nature of javascript. Let's look at the example: setTimeout(function test() { //your code setTimeout(test, 100); }, 100); setInterval(function() { //your code }, 100); These 2 blocks of code appear to be the same, but that's not the case due to single-threaded nature of javascript. With setInterval(): if your code is busy executing and takes long time to complete. The next intervals may fire while your code is still executing and these intervals will be queued up. In the end, you may end up with some handlers running in succession without any delay With setTimeout(): the next interval is only set to be fired when you're current code h

How can I set a timer to end at 12pm PST every day?
You could get the time from your server and parse it in JavaScript. If you're using PHP you could do something like this: var serverTime = Date.parse('<?= date("r"); ?>'); This will let PHP echo an RFC2822 formatted date and JavaScript will parse it and return a Date object. From here you can continue with the other solutions you have. I haven't tested this but the key is to get the time from your server and parse it in JavaScript (if the server isn't in the correct time zone you can just adjust the time). Update: Handling timezones. To take timezones into account you could use the DateTime object in PHP like this: $datetime = new DateTime(); $datetime->setTimezone('Pacific/Nauru'); and then echo it to your JavaScript like this: var serverTime = Date.parse('<?= $datet

While loops with timer in c++
Condition explanation Change your loop condition too: while ((timeLeft <= cd) && (guessWord.compare(originalWord) != 0)) You will break out if either of the conditions fail. This is because the result of the && is false if either condition fails. So this will continue while a) You have time left and b) you have not guessed the word. Yur use of || will make the loop continue while either is true (thus both have to fail for the loop to exit). Note: I personally think extra braces () are nice hear to make the expression more human readable. For an inexperienced programmer, they will not need to guess(look up) at the order of precedence Time Left Calculation: time_t start = time(0); // Make the start time absolute and outside the loop.
