backgroundworker

I'm writing a game server in node.js, and some operations involve heavy computation on part of the server. I don't want to stop accepting connections while I run those computations -- how can I run them in the background when node.js doesn't support threads? I can't vouch for either of these, personally, but if you're hell-bent on doing the work in-process, there have been a couple of independent implementations of the WebWorkers API for node, as listed on the node modules page: http://github.com/cramforce/node-worker http://github.com/pgriess/node-webworker At first glance, the second looks

I get this error if I click a button that starts the backgroundworker twice. This BackgroundWorker is currently busy and cannot run multiple tasks concurrently How can I avoid this? Simple: Don't start the BackgroundWorker twice. You can check if it is already running by using the IsBusy property, so just change this code: worker.RunWorkerAsync(); to this: if( !worker.IsBusy ) worker.RunWorkerAsync(); else MessageBox.Show("Can't run the worker twice!"); Update: If you do actually need to launch multiple background tasks at the same time, you can simply create multiple BackgroundWorker objects

I want to create a background worker for a WinForm that triggers code whenever midnight rolls by. I have an idea of how to do it, but I'm pretty sure it's not the best way to do it. while(1==1) { //if Datetime.Now == midnight, execute code //sleep(1second) } Use a System.Timers.Timer and at application start up just calculate the difference between DateTime.Now and DateTime.Today.AddDays(0) . Then set the interval for that amount. I actually did something just like this recently: public static class DayChangedNotifier { private static Timer timer; static DayChangedNotifier() { timer = new

I need to create queue and use it with BackgroundWorker. So I can add operations and when one is done next is starting in background. I found this code by google: public class QueuedBackgroundWorker<T> { public void QueueWorkItem( Queue queue, T inputArgument, Func<T> doWork, Action workerCompleted) { if (queue == null) throw new ArgumentNullException("queue"); BackgroundWorker bw = new BackgroundWorker(); bw.WorkerReportsProgress = false; bw.WorkerSupportsCancellation = false; bw.DoWork += (sender, args) => { if (doWork != null) { args.Result = doWork(new DoWorkArgument<T>((T)args.Argument));

I was unable to find an answer to this question anywhere... What happens with the exceptions thrown in the callback method for System.Threading.Timer, (or in the event handler for System.Timers.Timer). Is the exception propagated to the thread on which the timer was created or is the exception lost? What are the side-effects of throwing an exception within the timer's callback functions? What would be the right way to signalize to the timer's creation thread that the exception in the worker thread (callback method) has been thrown? Thanks for your time. The exception is not passed back to the
