synchronous

问题 I started Windows Phone programming with this example from Microsoft: http://code.msdn.microsoft.com/wpapps/Hybrid-Web-App-75b7ef74/view/SourceCode The app only displays the browser and load a URL. Now I want to load an other URL directly from a .txt file. For example: http://www.test.de/appurl.txt and then I want to load the URL in the Windows Phone App. --> For example: http://anotherserver.de/index.html?mobileApp My problem is, that the URL have to load synchronous and not asynchronous. I

问题 What I am trying to do is append a loading image to a div (so the user knows something is loading) and then I call a jquery ajax function, which is set to "async: false". Here is my code: $jQuery("#playersListDiv").html(loadingImage); $jQuery.ajax({ type: "POST", /* this goesn't work with GET */ url: urlValue, /*ex: "NBAgetGamesList.php" */ data: parameters, /*ex: "param1=hello" */ cache: false, async: false, success: function(data){ } }); The problem is that the browser locks and does not

问题 I am writing a Visual C# program that executes a continuous loop of operations on a secondary thread. Occasionally when that thread finishes a task I want it to trigger an eventhandler. My program does that but the when the event handler is triggered, the secondary thread waits until the event handler is finished before continuing the thread. How do I make it continue? Here is the way I currently have it structured... class TestClass { private Thread SecondaryThread; public event EventHandler

问题 I know this question has been asked countless times, but I cant figure out for the life of me how to make this answer work in my case: wait for async javascript function to return I'm looping through some "tv channels" in the outerloop and then looping through dates in the week in the innerloop. In the inner loop I make a ajax request to a server to fetch the data and I then store/cache it for later use like so var dates = []; //<-- Contains a list of dates for the coming week var baseUrl =

问题 The use and effects of the O_SYNC and O_DIRECT flags is very confusing and appears to vary somewhat among platforms. From the Linux man page (see an example here), O_DIRECT provides synchronous I/O, minimizes cache effects and requires you to handle block size alignment yourself. O_SYNC just guarantees synchronous I/O. Although both guarantee that data is written into the hard disk's cache, I believe that direct I/O operations are supposed to be faster than plain synchronous I/O since they

问题 I am still new to nodejs and developing my own asynchronous functions. According to the stack trace, I am looking at, I am being told that the following code is getting called back twice. Specifically the catch callback. Is there a better way to structure this so if more than one of the variables in the try blows up it only calls back once? As near as I can tell, since all of the buffer reads are done asynchronously if more than one error out they would all call the catch pretty much at the

问题 I search on the web, but what I found is not what I expect. I have a function with a block inside, and this function return before doing the treatment into the block. So my function return nil... NSString* returnTheFolder() { NSUserDefaults* userDefaults = [NSUserDefaults standardUserDefaults]; GTLServiceDrive *service; __block NSMutableDictionary* titlesAndIdentifiers; __block __strong NSString* rootFolder; __block NSArray* allIdentifiers; NSString* userDefaultValue = [userDefaults

问题 I developed a game in web technology that store the data in LocalStorage. The LocalStorage works as synchronous.To set and get the values from localstorage as // set the value in localstorage localStorage.setItem('Key', "value"); // get the value from localstorage var localValue = localStorage.getItem('Key'); There is 5MB limit in localstorage. After play the some level, localstorage filled completely. I need a large area for storage at client side. My first question is that “What is the best

问题 My list in my activity called AllStores contains only null. I need this list, because I want to populate my ListView later on. The problem is caused because my callback is getting executed as last. To clarify I have made a screenshot below: Link: http://i.imgur.com/bIkWjld.png The screenshot also tells what I actually want. To achieve that I had tried it with a AsyncTask . However it didn't worked out as you can see in the screenshot. Here is the code: EDIT 2.0 I have changed my getSubprise()

问题 I am looping over an array to update its values using returned value from called function which internally calls an asynchronous function . I need to handle asynchronous function in synchronous way which is not being directly called. This is replication of scenario . function condition(){ // Code of this function is not accessible to me. return new Promise(function(resolve, reject){ setTimeout(function(){ if(parseInt(Math.random() * 100) % 2){ resolve(true); } else{ reject(false) } }, 1000) }
