Hello, I want to implement a timer queuing system using the C++ STL priority_queue container adapter. My problem is that I want to occasionally cancel a timer, however there are no interfaces that enable me to easily delete an item in the priority_queue that is not the top item. Any suggestions?. Thank you for your help. ...
Hi Can anyone tell me if its possible to change the interval of an NSTimer while its firing? Seems like this should be possible but haven't figured out how... Basically I'm trying to create a 'deceleration' effect. ...

So I just want to write this quick and dirty module to a program that takes the current time, echos a string, and then waits x minutes and echos another string. The only thing is, is this little module stops the rest of the program until it's finished. Any way around this? ...
Hi I'm new to working with timers on the iPhone and would need some support. I have a method as below that takes the time and update a label in my user interface. I also have an NSTimer that calls that method once a second (I only show hours and minutes). This works just fine, except for the first second the App is live (as I understa...
How to pass parameters to the function called by ElapsedEventHandler? My code: private static void InitTimer(int Index) { keepAlive[Index] = new Timer(); keepAlive[Index].Interval = 3000; keepAlive[Index].Elapsed += new ElapsedEventHandler(keepAlive_Elapsed[, Index]); keepAlive[Index].Start(); } public static void keep...
I have an application which makes use of System.Timers.Timer objects to do expirations and email notifications and such. Currently the system has a couple hundred timers alive at once, but we are going to be expanding the usage of the app and that number might start scaling into the thousands (probably no higher than 10,000). I can't fi...
From my readings, it seems that ScheduledExecutorService is the right way to start and stop timers in Java. I need to port some code that starts and stops a timer. This is not a periodic timer. This code, stops the timer before starting it. So, effectively every start is really a restart(). I am looking for the right way to do this usin...
I am writing a count down timer, using .postdelayed(), that speaks each second as the timer goes down to zero. I have trouble understanding the consequences of the user hitting the back or home button. The countdown continues when hitting either button. When home is pressed and you reclick the app, it goes back to the same count(this...
Is it possible to skip to the end of a process's allocated time-quantum? I have a program that works in parallel on a piece of shared memory, and then all of the processes need to wait for the others to finish and sync up before the next step. Each process will do a maximum of one iteration more than any other, so any timing difference...
Hi, I know there have been a lot of topics like this but I just have problem to which I couldn't find the answer.

I have a system that needs at least 10 mseconds of accuracy for timers. I went for timerfd as it suits me perfectly, but found that even for times up to 15 milliseconds it is not accurate at all, either that or I don't understand how it works. The times I have measured were up to 21 mseconds on a 10 mseconds timer. I have put together...
On SO, there are quite a few questions about performance profiling, but I don't seem to find the whole picture. There are quite a few issues involved and most Q & A ignore all but a few at a time, or don't justify their proposals. What Im wondering about. If I have two functions that do the same thing, and Im curious about the differenc...
Hello everyone, I just have a one quick question on Timer and TimerEvent (flash.events.TimerEvent & flash.utils.Timer) of Adobe Flex. I am currently working on a project wherein I need to occasionally change speed, stop and play an swf animation (loaded to a loader and instantiated as a ByteArray). Example, I have a moving car (swf ...

Hi all, Thanks for taking time to read this question. I am designing a 3-tier solution written in c# that needs to carry out processing every minute. The processing should be initiated at the same time from different unconnected parts of the program. What's the best way to implement a system-wide timer? Should it be in the business ...
hi First, sorry for my bad english writing. Suppose that we have a win form (C#) that has a timer. The timer interval has been set to 60000 milsec. So its tick event will be fired every 1 milute. Suppose we have written a method that handles tick event called Timer1_Tick. What if the job needs more that 1 minute to complete? ...

I want to set a machine timer resolution to 0.5ms. Sysinternal utility reports that the min clock resolution is 0.5ms so it can be done. P.S. I know how to set it to 1ms. P.P.S. I changed it from C# to more general question (thanks to Hans) System timer resolution ...
