阅读更多关于 JobScheduler - How to skip first job run of periodic job?

问题 in my app i have set a periodic job that is set to run every 30 minutes. The first job run occurs right when I do schedule that periodic job, which is not wanted in my case. What I want is to skip the first run so that it will run for the first time after 30+ minutes. My two thoughts on how to approach this was to either have it not run at all for the first 30 minutes somehow (some kind of delay), or mark the first job run as done before even having the chance to start. Unfortunately I have

阅读更多关于 How to reset a Task.Delay() after a event fired?

问题 I am trying to let some code fire after my FileSystemWatcher hasn't received any changes for more then 5 minutes. My current approach is to call a await Task.Delay(); after a change, hoping the user is done by then. This obviously is not the way to go. So my question: How to reset a Task.Delay() after a event fired? 回答1: You can't "reset" a Task.Delay , but you can reset a timer which makes it an ideal candidate to solve this problem. Here's an example: private System.Threading.Timer timer;

问题 How can I start 5 different processes, each with their own delay without holding up the other ones while waiting for the delay to finish? I can not use async or await foreach(string process1 in _processList) { // random delay Process.Start(process1); } 回答1: You could start every process from a different thread. foreach (string process1 in _processList) { Thread t = new Thread(() => { Thread.Sleep(/*RANDOM NUMBER*/ 5); Process.Start(process1); }); t.Start(); } That way each process will have a

Delay between Preloader and Stage shown

阅读更多关于 Delay between Preloader and Stage shown

问题 I have a program that uses a simple preloader while the init() method creates the main gui. Everything works fine but after the init() method completes and the preloader disappears, there's a noticeable delay before the main stage shows up. I say noticeable because it can be as much as 7 seconds, enough for a user to get confused. I tried to put as little as possible in the start() method: public void start(Stage stage) { /*Scene*/ scene = new Scene(root, 1200, 700); stage.setScene(scene);

I want to trigger onChange after a delay from last change

阅读更多关于 I want to trigger onChange after a delay from last change

问题 Basically, I have an angular application, and I would like to have (change) only be triggered after a few seconds of nothing happening. Therefore instead of sending requests every time a letter is written in an input field, only after writing a letter and nothing happening for a few seconds, then the request would be sent. 回答1: You may use rxjs debounceTime piped to the valueChanges observable of the reactive FormControl as in the example at https://stackblitz.com/edit/angular-debounce-form
