I have a TThread which receives and sends to a device on a COM port. After I read the data, I want to activate the GUI (not in the same thread) using Synchronize(function name). However, when I call the GUI's form function to perform a button click, I get an access violation. I checked to see if the form's value is null and it is not, si...
I am using a System.Windows.Forms.Timer component on an application's main form which checks every minute for updates on a database. However, there are a number of possible interactions with the user, such as modal dialogs being thrown for certain operations. In general, I don't want this timer to fire when the user is "busy" or while an...
I have a timer in a windows service (.NET C#). I need to be able to change the elapsed value from an external program. If the timer is currently running, I need to be able to shorten the time elapsed value from an external program. I was thinking of having a public method in the service that would change the timer elapsed value and r...
We would like to have some periodic actions executed by our WCF service hosted in IIS. What is the best way to do this...Creating a timer doesn't look as a good solution. Creating a windows service that would behave as some kind of a heart beat looks like a problem solution, but it still doesn't smell good. What approach will be a good s...
My question is when the timer is start ticking. Let's take for example, timer that configured to tick every second and I start my program on hh:mm:ss:ms = 22:40:34.50. The tick will start on round sec? Start on 17:40:35.00 or it's start on the exact time? So the first tick will be on 17:40:35.50 and the next one on 17:40:36.50. What ac...

[Cocoa/Objective-C] I adapted a timer routine (for current time) from this site (and it works great - thanks). It's currently attached to a button. My question is: How do I make it start when my app starts up (and not use a button) (in other languages, I'd simply put the action listener or timer in the Form)...? Thank for any help on...
Im building an automatic refreshing comment section for my website using jQuery .load. So I am using a javascript 'setTimeout' timer to check for new comments.

I tried calling cancel() on a timer but that causes the function passed into async_wait to be called immediately. Whats the correct way working with timers in a async tcp client? ...
Ok, I know an object of System.Timer executed in the thread-pool, rather than in the UI thread. I also know that the System.Timer is thread-safe. Say I have a collection of System.Timer objects. I can have all of them run and (unless i'm mistaken) they'll actually execute in the thread-pool. Say I instead create a collection of thre...
Hi, I've been experiencing memory problems (the app will run for a couple of iterations, then receive low memory warning and finally be terminated) while working with NSInvocationOperation in a method called repeatedly by a NSTimer. The method will be called every 1/4 of a second and I've narrowed down the source of the problem to the ...
