Flex 3: synchronously loading an xml file

会有一股神秘感。 提交于 2019-12-07 15:20:15
问题 My question is very simple: In flex3, is there a way to load an xml file synchronously? I know how to load asynchronously, using a load event. This may be useful, or may not. I just want to read the file, parse it, do what I have to do with it, and continue executing code. I have a component that uses an xml file to store some configuration parameters. I need to read the file when the object is initialized. However, with the event model, I can't control when the file is loaded, so I must

Synchonous SSL certificate handling on iPhone

问题 I was wondering if anyone can help me understand how to add SSL certificate handling to synchronous connections to a https service. I know how to do this with asynchronous connections but not synchronous. NSString *URLpath = @"https://mydomain.com/"; NSURL *myURL = [[NSURL alloc] initWithString:URLpath]; NSMutableURLRequest *myURLRequest = [NSMutableURLRequest requestWithURL:myURL cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60]; [myURL release]; [myURLRequest

Run gulp task after completion of other task

一曲冷凌霜 提交于 2019-12-06 08:24:11
问题 I have two sets of files, let's call them base and mods . The mods files override the base files, so when I run the gulp task related to base , I need to run the mods task directly after. My setup is something like this: gulp.task('base',function(){ return gulp.src('base-glob') .pipe(...) .pipe(gulp.dest('out-glob')) }); gulp.task('mods',function(){ return gulp.src('mods-glob') .pipe(...) .pipe(gulp.dest('out-glob')) }); So I want to run the mods task at the completion of the base task. Note

Getting Initial Value for LiveData Always Returning Null

浪尽此生 提交于 2019-12-06 07:33:40
I am trying to load the loggedInUser from the Local Room Database, when the App starts. I would like to skip prompting user to log-in if the saved Authentication Token of the previously saved user is still valid! So, from the DAO , I want to return a LiveData object containing the previously logged-in user , then observe it for subsequent changes. The challenge I have is that the method to get the currently logged-in user always returns null if I wrap the result inside a LiveData , but it returns the expected user if returned as a POJO . How can I force LiveData to run synchronously just to

Are handlers always called synchronously during jQuery click()?

前提是你 提交于 2019-12-06 04:39:19
问题 Through some brief testing it appears that click() will trigger any applicable handlers synchronously (that is, the handlers are all invoked before click() returns), which is desirable for what I'm developing. However, the jQuery documentation does not seem to guarantee (does not mention one way or the other) that handlers are invoked synchronously. Is a synchronous behavior guaranteed somewhere, or otherwise safe to assume as cross-browser and future-proof? 回答1: Yes, behind the scenes all

Synchronous AJAX call fails on iPad, but not other platforms and browsers

时间秒杀一切 提交于 2019-12-06 04:23:27
问题 Does anyone know why a synchronous ajax call would fail and give the following error on Safari on an iPad, but the same code works fine on all other platforms and browsers I've tested so far? NETWORK_ERR: XMLHttpRequest Exception 101: A network error occurred in synchronous requests. That error suggests that I'm attempting a cross-domain request, but I'm not; the requested URL is on the same host, and in fact it's a relative URL. Even in trivial tests, this fails on the iPad (and works on all

Obtain data synchronously from WebWorker?

假装没事ソ 提交于 2019-12-06 02:05:20
问题 While I understand that JavaScript is inherently single-threaded and generally frowns upon such things, I am wondering if there is any way to get a WebWorker to wait until some data is made available from the main thread without destroying the call stack of the WebWorker. As this is for a fun project, I can use new technologies and things that won't reliably run on older browsers, and I don't mind esoteric hacks as long as they work. Some other solutions that I have thought about:

Can I read from a socket synchronously using Boost.Asio with a timeout on a multithreaded I/O service?

僤鯓⒐⒋嵵緔 提交于 2019-12-05 21:49:49
问题 I have an application that uses Boost.Asio for TCP and UDP socket communications. I understand that the 'A' in "Asio" stands for Asynchronous , so the library is bent toward encouraging you to use asynchronous I/O when possible. I have a few cases where synchronous socket reads are preferable. At the same time, however, I would like to set a timeout on said receive calls, so there's no possibility of the read blocking indefinitely. This appears to be a pretty common problem among Boost.Asio

Synchronous XHR deprecation

随声附和 提交于 2019-12-05 21:43:40
According to xhr specs async: false is deprecated and modern user agents should start to warn about or even to throw exception. Synchronous XMLHttpRequest outside of workers is in the process of being removed from the web platform as it has detrimental effects to the end user's experience. (This is a long process that takes many years.) Developers must not pass false for the async argument when the JavaScript global environment is a document environment. User agents are strongly encouraged to warn about such usage in developer tools and may experiment with throwing an InvalidAccessError
