Is there a way to make powershell wait for an install to finish?

由 回眸只為那壹抹淺笑 提交于 2019-12-21 04:52:17
问题 I have a list of Windows packages that I'm installing via powershell using the following command: & mypatch.exe /passive /norestart mypatch.exe is being passed from a list and it doesn't wait for the prior install to finish - it just keeps going. It builds up a huge window of installs that are pending installation. Also, I can't use $LASTEXITCODE to determine if the install succeeded or failed. Is there anyway to make the installs wait before starting the next? 回答1: Start-Process <path to exe

ElasticSearch updates are not immediate, how do you wait for ElasticSearch to finish updating it's index?

由 白昼怎懂夜的黑 提交于 2019-12-20 17:58:07
问题 I'm attempting to improve performance on a suite that tests against ElasticSearch. The tests take a long time because Elasticsearch does not update it's indexes immediately after updating. For instance, the following code runs without raising an assertion error. from elasticsearch import Elasticsearch elasticsearch = Elasticsearch('es.test') # Asumming that this is a clean and empty elasticsearch instance elasticsearch.update( index='blog', doc_type=,'blog' id=1, body={ .... } ) results =

Wait for 5 seconds

问题 I want to wait 5 seconds before starting another public void method. The thread sleep was not working for me. If there is a way of wait() without using Threads I would love to know that. public void check(){ //activity of changing background color of relative layout } I want to wait 3 seconds before changing the relative layout color. 回答1: just add one-liner with lambda (new Handler()).postDelayed(this::yourMethod, 5000); 回答2: See if this works for you. Be sure to import the android.os

Set up a real timeout for loading page in Selenium WebDriver?

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-20 09:37:02
问题 I'm testing a site with lots of proxies, and the problem is some of those proxies are awfully slow. Therefore my code is stuck at loading pages every now and then. from selenium import webdriver browser = webdriver.Firefox() browser.get("http://example.com/example-page.php") element = browser.find_element_by_id("someElement") I've tried lots of stuff like explicit waits or implicit waits and been searching around for quite a while but still not yet found a solution or workaround. Nothing

问题 I want to change my UILabel 's text after 2 seconds. I tried setting my UILabel 's text to "A text" , and use sleep(2) and finally changing the text to "Another text" . But sleep(2) only freezes the app and "Another text" is set without displaying "A text" for 2 seconds. How may I display "A text" for 2 seconds and then show "Another text" ? 回答1: You can use [self performSelector:@selector(changeText:) withObject:text afterDelay:2.0]; or if you want to display it periodically, check the

Can a thread call wait() on two locks at once in Java (6)

由 筅森魡賤 提交于 2019-12-20 07:23:56
问题 I've just been messing around with threads in Java to get my head around them (it seems like the best way to do so) and now understand what's going on with synchronize, wait() and notify(). I'm curious about whether there's a way to wait() on two resources at once. I think the following won't quite do what I'm thinking of ( edit : note that the usual while loops have been left out of this example to focus just on freeing up two resources ): synchronized(token1) { synchronized(token2) { token1

Python: Accept input while waiting [duplicate]

问题 This question already has answers here : How to set time limit on raw_input [duplicate] (6 answers) Closed 4 years ago . I have a small script that I have written to perform tasks every 5 minutes (this does not need to be exact), but as it is written currently the only way it can be cancelled is with Ctrl+Z (linux terminal) and there is no way of changing what set of tasks it performs without restarting the script. As a result, I'd like to change the script to be able to accept user input

Why does Threads in BLOCKED state do not get interrupted?

由 此生再无相见时 提交于 2019-12-20 03:03:10
问题 Off late i am working on multithreading in java. Want to understand if a Thread is in BLOCKED state why it cant be interrupted? And why the thread can be interrupted only if it is in WAIT state? Basically, why do we need two Thread states one which can be interrupted and the other which cant be interrupted? This question might be very basic but, I am trying to understand things rather than just remembering them. 回答1: One assumes that you mean cause the thread to stop its current operation and

C# Make Program Wait For Button To Be Pressed

由 為{幸葍}努か 提交于 2019-12-19 18:29:56
问题 I want to make the program wait for a button to be pressed before it continues, I tried creating a while loop and having it loop until the button is clicked and sets a bool to true for the while loop to end, this made it crash while (!Redpress) { //I'd like the wait here } Redpress = false; It doesn't matter whether or not the while is there, as long as the program waits for the button press before setting "Redpress" to false... Any Ideas? 回答1: Use events - it's what they're designed for. You
