task

问题 I had a problem with catching my exception from Task.Run I changed my code and my problem solved. I'm willing to figure out what is the difference between handling exceptions inside Task.Run in these two ways : In Outside function I can't catch the exception but in Inside I can catch it. void Outside() { try { Task.Run(() => { int z = 0; int x = 1 / z; }); } catch (Exception exception) { MessageBox.Show("Outside : " + exception.Message); } } void Inside() { Task.Run(() => { try { int z = 0;

问题 I am trying to properly understand and implement two concurrently running Task objects using Python 3's relatively new asyncio module. In a nutshell, asyncio seems designed to handle asynchronous processes and concurrent Task execution over an event loop. It promotes the use of await (applied in async functions) as a callback-free way to wait for and use a result, without blocking the event loop. (Futures and callbacks are still a viable alternative.) It also provides the asyncio.Task() class

问题 There are many places across the web and Stack Overflow where one is discouraged from changing the priority of a ThreadPool thread or TPL Task . In particular: "You have no control over the state and priority of a thread pool thread." "The runtime manages the thread pool. You have no control over the scheduling of the thread, nor can you change the thread's priority." "You should not change the Culture or Priority or... of a PoolThread. Just like you don't paint or re-decorate a rental car."

问题 I am running selenium tests inside a for loop which takes time. I needed to indicate the progress of those tests using javafx progressbar . So I replaced the code inside for loop with a task. Following is my code The runTests() method returns a String which is displayed as an Alert I cannot return a String from inside Task<Void> as the return type is Void The test code is inside runTest(data) method which returns true or false @FXML private void handleRunTestButton(ActionEvent aEvent) throws

问题 I've made a program for the USACO task and now I just can't figure out why I'm getting the bad answer, I've been thinking why for a long time and still didn't figure it out. What could be wrong? The task is to count the number of times the 13th falls on Saturday, Sunday, Monday, Tuesday, ..., Friday. The year from when to test is 1900 and the last year is given in the txt file. Instead of this answer: 36 33 34 33 35 35 34 I'm getting: 34 33 33 33 36 36 35 Thank you very very very much for you

问题 I am executing a task from an action in Symfony. I wish to capture the output from the task & display it to the (admin) user. Do I extract it from the dispatcher / log or somewhere else? 回答1: This might not be the answer you're looking for, however, in a task you can log to a seperate file like so (within the execute function in the task class): $fileLogger = new sfFileLogger($this->dispatcher, array('file' =>$this->configuration->getRootDir().'/log/foobar.log')); $this->dispatcher->connect(

问题 I have the following question. How can I end a user task in alfresco with method? I am trying to fix a alfresco's bug, which it doesn't allow me to have only a service task in a whole process. So I include a user task, but i want to auto-complete it (end it)... I have tried many things but nothing seem to work. What else can i do?
