you can require the user to hit enter before closing the program… something like this works. #include <iostream> int main() { std::cout << “Hello, World\n”; std::cin.ignore(); return 0; } The cin reads in user input, and the .ignore() function of cin tells the program to just ignore the input. The program will continue once the … Read more
I think what you are after is Task.Delay. This doesn’t block the thread like Sleep does and it means you can do this using a single thread using the async programming model. async Task PutTaskDelay() { await Task.Delay(5000); } private async void btnTaskDelay_Click(object sender, EventArgs e) { await PutTaskDelay(); MessageBox.Show(“I am back”); }
If you are interested in knowing when a certain task completes, or a certain batch of tasks, you may use ExecutorService.submit(Runnable). Invoking this method returns a Future object which may be placed into a Collection which your main thread will then iterate over calling Future.get() for each one. This will cause your main thread to … Read more
“Invoking wait inside a synchronized method is a simple way to acquire the intrinsic lock” This sentence is false, it is an error in documentation. Thread acquires the intrinsic lock when it enters a synchronized method. Thread inside the synchronized method is set as the owner of the lock and is in RUNNABLE state. Any … Read more
Depending on what you want to do, you can try: browser.waitForAngular(); or btnLoginEl.click().then(function() { // do some stuff }); to solve the promise. It would be better if you can do that in the beforeEach. NB: I noticed that the expect() waits for the promise inside (i.e. getCurrentUrl) to be solved before comparing.
The second test has two nested tasks and you are waiting for the outermost one, to fix this you must use t.Result.Wait(). t.Result gets the inner task. The second method is roughly equivalent of this: public void TestAwait() { var t = Task.Factory.StartNew(() => { Console.WriteLine(“Start”); return Task.Factory.StartNew(() => { Task.Delay(5000).Wait(); Console.WriteLine(“Done”); }); }); t.Wait(); … Read more
I wrote a super simple delay function for an application I developed in Qt. I would advise you to use this code rather than the sleep function as it won’t let your GUI freeze. Here is the code: void delay() { QTime dieTime= QTime::currentTime().addSecs(1); while (QTime::currentTime() < dieTime) QCoreApplication::processEvents(QEventLoop::AllEvents, 100); } To delay an event … Read more
Edit 2018: Please look into Object getters and setters and Proxies. Old answer below: a quick and easy solution goes like this: var something=999; var something_cachedValue=something; function doStuff() { if(something===something_cachedValue) {//we want it to match setTimeout(doStuff, 50);//wait 50 millisecnds then recheck return; } something_cachedValue=something; //real action } doStuff();
var img = new Image(); img.onload = function() { alert(“Height: ” + this.height); } img.src = “http://path/to/image.jpg”; Note that it’s important to do it in the order above: First attach the handler, then set the src. If you do it the other way around, and the image is in cache, you may miss the event. … Read more
Thread sleep always takes a time how long to wait: https://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html#sleep(long) public static void sleep(long millis) throws InterruptedException e.g. Thread.sleep(1_000) // wait for 1 second If you want to wait for some other Thread to wake you, maybe `Object#wait()’ would be better https://docs.oracle.com/javase/7/docs/api/java/lang/Object.html#wait() public final void wait() throws InterruptedException Then another thread has to call … Read more
