  • How to do a comet long pulling with ActionScript3?

    - by Victor Lin
    I want to load data from my web server, I want it be the AJAX/Comet way, my web-server long holds the request, response it until something happened. Thus, I wrote some as3 code like this: private function load(): void { var request:URLRequest = new URLRequest(url); var variables:URLVariables = new URLVariables(); variables.tick = this.tick; request.data = variables; urlLoader = new URLLoader(request); urlLoader.addEventListener(Event.COMPLETE, onComplete); urlLoader.addEventListener(IOErrorEvent.IO_ERROR , onIOError); log.info("Loading info from {0}", request.url); } It works, if the waiting time is short, but however, it failed with IOError 2032, seems the waiting time is out. Here is the problem, how can I do a long-polling with as3 and avoid the timeout error? Thanks.

  • whats faster, more efficient, loading a js file with arrays or populating arrays from tables

    - by Leigh
    I am rebuilding an ecom site where the product data is stored in a multidimensional JS array that gets loaded on page load. This data is constantly being accessed with JS due to the nature of the site, to update prices based on user selections. There are many options that affect final price. From a programming standpoint, a DB table is much easier to maintain and update than are JS arrays, and since I am porting the site over to PHP and MYSQL, I have been considering moving these arrays into tables. So, would it be better to populate an array from the DB on load so that the pricing data is always available to the JS, or stay with hard coded JS files? I considered getting data via ajax as needed, but since this site has to constantly update pricing with user interaction, I have pretty much ruled that out. How would you handle it?

  • jquery document ready with Google

    - by cf_PhillipSenn
    This is how I load jQuery: <script src="http://www.google.com/jsapi"></script> <script type="text/javascript"> function OnLoad() { insert jQuery goodness here }; google.load("jquery", "1"); google.setOnLoadCallback(OnLoad); </script> But instead of function OnLoad() {, I'd like to use $(document).ready(function() {} so that it's like every example in every book and documentation snippet. How can I define: $ = jQuery?

  • How to cancel a web service call if it's not responding

    - by drizzle
    Hi, I have a web page (.aspx) that calls a third party web service to get some data. It usually takes couple of seconds to get the response back, and then the rest of the page will load. Occasionally the call gets stuck either due to the web service is down, or internet connection, etc., the page just hang there and will not load. My questions is: 1) Is there a way to abort/cancel the web service call after a set amount of time? 2) Is it even possible to verify the status of the web service before calling it? Thanks.

  • With Choice Comes Complexity

    - by BuckWoody
    "Complex" may be defined as "Having many steps, details or parts." Many of Microsoft's products, including SQL Server, can be complex. I'm stating what most data professionals already know - there's usually multiple ways to do things in SQL Server. For instance, to import some data into a table you can use graphical tools, SQLCMD, bcp, SQL Server Integration Services, BULK INSERT, even PowerShell, just to name a few tools at your disposal. That's really not the issue, though. The bigger issue is that there are normally multiple thought-processes, or methods, that you have available for a task. That's both a strength and a weakness. If things were more simple, you would have fewer choices. Sometimes that's a good thing. Just tell me what I need to do and I'll do it. However, your particular situation may not fit that tool or process, so having more options increases your ability to get your job done the way you need to do it. On the other hand, that's more for you to learn, which is harder. There's another side of this benefit/difficulty that you need to be aware of. Even if you're quite good at what you do, keep in mind that the way you know how to do something may not be the only way to do it. Keep your mind open to new possibilities, and most importantly - to new knowledge. SQL Server professionals teach me something new every day. So embrace the complexity - on balance, it's a good thing! Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Which programming language to choose? (for a specific problem/domain, details inside)

    - by Bijan
    I am building a trading portfolio management system that is responsible for production, optimization, and simulation of non-high frequency trading portfolios (dealing with 1min or 3min bars of data, not tick data). I plan on employing Amazon web services to take on the entire load of the application. I have four choices that I am considering as language. a) Java b) C++ c) C# d) Python Here is the scope of the extremes of the project scope. This isn't how it will be, maybe ever, but it's within the scope of the requirements: Weekly simulation of 10,000,000 trading systems. (Each trading system is expected to have its own data mining methods, including feature selection algorithms which are extremely computationally-expensive. Imagine 500-5000 features using wrappers. These are not run often by any means, but it's still a consideration) Real-time production of portfolio w/ 100,000 trading strategies Taking in 1 min or 3 min data from every stock/futures market around the globe (approx 100,000) Portfolio optimization of portfolios with up to 100,000 strategies. (rather intensive algorithm) Speed is a concern, but I believe that Java can handle the load. I just want to make sure that Java CAN handle the above requirements comfortably. I don't want to do the project in C++, but I will if it's required. The reason C# is on there is because I thought it was a good alternative to Java, even though I don't like Windows at all and would prefer Java if all things are the same. Python - I've read somethings on PyPy and pyscho that claim python can be optimized with JIT compiling to run at near C-like speeds.... That's pretty much the only reason it is on this list, besides that fact that Python is a great language and would probably be the most enjoyable language to code in, which is not a factor at all for this project, but a perk. To sum up: - real time production - weekly simulations of a large number of systems - weekly/monthly optimizations of portfolios - large numbers of connections to collect data from There is no dealing with millisecond or even second based trades. The only consideration is if Java can possibly deal with this kind of load when spread out of a necessary amount of EC2 servers. Thank you guys so much for your wisdom.

  • Ninject: Abstract Class

    - by Pickels
    Hello, Do I need to do something different in an abstract class to get dependency injection working with Ninject? I have a base controller with the following code: public abstract class BaseController : Controller { public IAccountRepository AccountRepository { get; set; } } My module looks like this: public class WebDependencyModule : NinjectModule { public override void Load() { Bind<IAccountRepository>().To<AccountRepository>(); } } And this is my Global.asax: protected override void OnApplicationStarted() { Kernel.Load(new WebDependencyModule()); } protected override IKernel CreateKernel() { return new StandardKernel(); } It works when I decorate the IAccountRepository property with the [Inject] attribute. Thanks in advance.

  • Loading tables dynamically with NHibernate

    - by Trevor Goertzen
    I'm working on a project that requires me to load tables based on table names stored in another table. More tables will be added to the DB (and by someone else), so creating NHibernate mapping files for each table isn't an option. Does anyone know if it is possible to load tables dynamically using NHibernate? Edit: I should add that I'm on .NET 2.0, so I can't use Fluent NHibernate. Thanks for the suggestion though guys. I will use that as evidence in convincing my associates to upgrade.

  • javascript simple object creation test: opera leaks?

    - by joe
    Hi, I am trying to figure out certain memory leak conditions in javascript on a few browsers. Currently I'm only testing FF 3.6, Opera 10.10, and Safari 4.0.3. I've started with a fairly simple test, and can confirm no memory leaks in Firefox and Safari. But Opera just takes memory and never gives it back. What gives? Here's the test: <html> <head> <script type="text/javascript"> window.onload = init; //window.onunload = cleanup; var a=[]; function init() { var d = document.createElement('div'); d.innerHTML = "page loading..."; document.body.appendChild(d); for (var i=0; i<400000; i++) { a[i] = new Obj("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"); } d.innerHTML = "PAGE LOADED"; } function cleanup() { for (var i=0; i<400000; i++) { a[i] = null; } } function Obj(msg) { this.msg=msg; } </script> </head> <body> </body> </html> I shouldn't need the cleanup() call on window.unload, but tried that also. No luck. As you can see this is simple JS, no circular DOM links, no closures. I monitor the memory usage using 'top' on Mac 10.4.11. Memory usage spikes up on page load, as expected. In FF and Safari reloading the page does not use any further memory, and all memory is returned when the window (tab) is closed. In Opera, memory spikes on load, and seems to also spike further on each reload (but not always...). But regardless of reload, memory never goes back down below the initial load spike. I had hoped this was a no-brainer test that all browsers would pass, so I could move on to more "interesting" conditions. Am I doing something wrong here? Or is this a known Opera issue? Thanks! -joe

  • BULK INSERT with inconsitant number of columns

    - by aceinthehole
    I am trying to load a large amount data in SQL server from a flat file using BULK INSERT. However, my file has varying number of column, for instance the first row contains 14 and the second contains 4. That is OK, I just want to make a table with the max number of columns and load the file into it with nulls for the missing columns. I can play with it from that point. But it seems that SQL Server when reaching the end of the line and having more columns to fill for that same row in the destination table, just moves on to the next line and attempts to put the data on that line to the wrong column of the table. Is there a way to get the behavior that I am looking for? Is there a table hint that I can use the specify this? Has anyone run into this before? Here is the code BULK INSERT #t FROM '<path to file>' WITH ( DATAFILETYPE = 'char', KEEPNULLS, FIELDTERMINATOR = '#' )

  • How Do I Pull Info from String

    - by Russ Bradberry
    I am trying to pull dynamics from a load that I run using bash. I have gotten to a point where I get the string I want, now from this I want to pull certain information that can vary. The string that gets returned is as follows: Records: 2910 Deleted: 0 Skipped: 0 Warnings: 0 Each of the number can and will vary in length, but the overall structure will remain the same. What I want to do is be able to get these numbers and load them into some bash variables ie: RECORDS=?? DELETED=?? SKIPPED=?? WARNING=?? In regex I would do it like this: Records: (\d*?) Deleted: (\d*?) Skipped (\d*?) Warnings (\d*?) and use the 4 groups in my variables.

  • Prototype Ajax.Updater Response OK, but not showing up in FF. working in Safari!

    - by koko
    Hi, I've got a quite strange problem here. I'm calling some simple code via Ajax.Updater: new Ajax.Updater('load','http://myurl.com/demo.pl?key=demokey&param1=xyz&param2=abc',{ method:'get', onComplete:function(transport){ alert(transport.responseText) } }); which gets some code like this: <img id="2009_04_15_1239786246" src='../pv/100/2009_04_15_1239786246-01.jpg' border="1"> <img id="2009_04_15_1239786066" src='../pv/100/2009_04_15_1239786066-01.jpg' border="1"> ... and so on This code shows up in my firebug console as my server response, so everything should be fine. No errors here at all. Works fine in Safari. Firefox, according to Firebug, knows there is a response, but it won't show a thing in my div 'load' and the alert(transport.responseText) is also empty. I have no idea what could be the problem here.

  • Ajax, php, mysql not working mysql limit

    - by Hofmeister Ákos
    I have 3 files. list.php $articles = $mysqli->query("SELECT mainPictureBig, title, writer, writeDate, link FROM articles WHERE category=$this->category ORDER BY writeDate DESC LIMIT 0,10"); while($article = mysqli_fetch_row($articles)) { echo "<a href=\"".$this->url."/".$article[3]."/".$article[4]."\"><div id=\"listElement\"> <div id=\"listElementWallpaper\" style=\"background-image: url('category/img.jpg');\"></div> <div id=\"listElementContent\"><div id=\"listElementTitle\">".$article[1]."</div>".$this->giveWriter($article[2]).", ".$this->giveDate($article[3])."</div> </div></a>"; } $maximumElements=ceil($numberOfContent / 10) * 10; It's working, so there is no problem, it lists the first 10 elements from the sql table, and i got the $numberOfCOntent part also. Than i have a button: echo "<div id=\"listMore\"><div id=\"buttonOne\" onclick=\"listMore($this->category,$maximumElements)\">Load more</div></div>"; There is also no problem, i load the .js file, and it looks like: var from = 10; function listMore(categoryId, maximum) { $( "#listMore" ).slideUp( 200, function() { $( "#listMore" ).html("<center>Loading..</center>"); $( "#listMore" ).slideDown( 500, function() { $.post( "http://localhost/ajax.php", {type: "listMore", id: categoryId, sqlFrom: from} ) .done(function( elements ) { $("#listBody").append( elements ); if(maximum > from+10) { from = from+10; $( "#listMore" ).slideUp(200, function() { $( "#listMore" ).html("<div id=\"buttonOne\" onclick=\"listMore("+categoryId+","+maximum+")\">Load more</div>"); $( "#listMore" ).slideDown(200); }); } else $( "#listMore" ).slideUp(200); }); }); }); } And it's also working, and the problem is in the PHP file. As you can see, i'm sending an integer the "from" variable, the PHP file: $articles = $mysqli->query("SELECT mainPictureBig, title, writer, writeDate, link FROM articles WHERE category=$id ORDER BY writeDate DESC LIMIT $from,10"); It's also working, but not loading the next 10, only the next 9. So it skips the very next row and loads the rows only after the very first, so only 9. I tried to write here only the important part of the code, so i skipped some echo part etc. Any idea?

  • Application error with MyFaces 1.2: java.lang.IllegalStateException: No Factories configured for this Application.

    - by IgorB
    For my app I'm using Tomcat 6.0.x and Mojarra 1.2_04 JSF implementation. It works fine, just I would like to switch now to MyFaces 1.2_10 impl of JSF. During the deployment of my app a get the following error: ERROR [org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/myApp]] StandardWrapper.Throwable java.lang.IllegalStateException: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions! If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml. A typical config looks like this; <listener> <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class> </listener> at javax.faces.FactoryFinder.getFactory(FactoryFinder.java:106) at javax.faces.webapp.FacesServlet.init(FacesServlet.java:137) at org.apache.myfaces.webapp.MyFacesServlet.init(MyFacesServlet.java:113) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1172) at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:992) at org.apache.catalina.core.StandardContext.loadOnStartup(StandardContext.java:4058) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4371) ...

  • How to implement a lazy loaded Silverlight data grid without using paging

    - by Marc Wittke
    Using the Business Application template from the brand new released RIA Services, you can see lots of examples using the data grid on top of a DomainDataSource in combination with a DataPager. The properties PageSize and LoadSize can be used to adjust the amount of data to be displayed in one page and the data that is prefetched in the background. Now I'd like to have a data grid with a scrollbar and no pager. The underlying DomainDataSource should load only the data that is diplayed in the grid. It should trigger another load, when the user scrolls down to items that are not yet in the data context. Is there any sample implementation how to do this?

  • best method of turning millions of x,y,z positions of particles into visualisation

    - by Griff
    I'm interested in different algorithms people use to visualise millions of particles in a box. I know you can use Cloud-In-Cell, adaptive mesh, Kernel smoothing, nearest grid point methods etc to reduce the load in memory but there is very little documentation on how to do these things online. i.e. I have array with: x,y,z 1,2,3 4,5,6 6,7,8 xi,yi,zi for i = 100 million for example. I don't want a package like Mayavi/Paraview to do it, I want to code this myself then load the decomposed matrix into Mayavi (rather than on-the-fly rendering) My poor 8Gb Macbook explodes if I try and use the particle positions. Any tutorials would be appreciated.

  • java.lang.UnsatisfiedLinkError, mach-o but wrong architecture on Mac10.6.2

    - by Yinan
    I was trying to run a project in my local machine. I tried to load this jnilib file which I got from a running instance of this project on my Mac 10.6.2, System.load(lib.getAbsolutePath()); then I got this exception thrown: java.lang.UnsatisfiedLinkError, mach-o but wrong architecture I have check the jnilib with file command: libScreenMatchProxy.jnilib: Mach-O dynamically linked shared library i386 I guess this is because the jnilib file is compiled in 32bit but the Java comes with Mac10.6 is 64bit. So I go to Java Preference and set Java to use 32bit first. But it didn't work. As mentioned above, this jnilib file is copied from a running instance of the project on my Mac, so it should work. I don't understand why it working in the installed application but not in my Eclipse.

  • Background-image won't change using jquery in IE6

    - by slav
    There is a panel on my page with no default background-image css. On load it is set with jquery to an initial image, waits for 10 seconds then loads a random image out of some predetermined images. There are previous and next buttons which allow you to cycle through the images. In ie6 the initial image loads and then a random image also loads after 10 seconds, however pressing prev/next causes the background to become white and the images aren't loaded. With alerts I was able to find that it's still keeping track of the position and url of the image it's supposed to load, but just won't load it. Here is the code below. <script type="text/javascript"> var facts = new Array(); var position; $(document).ready(function() { <xsl:for-each select="$currentPage/ancestor-or-self::node[@level=1]/../node[@nodeName='Fun Fact Folder']/node"> facts[<xsl:value-of select="position()" />] = '<xsl:value-of select="." />'; </xsl:for-each> if(window.location.pathname == "/homepage.aspx" || window.location.pathname == "/") { $(".fun_facts_bg").css("background-image", "url(images/fun_fact_homepage.JPG)"); setTimeout("randomFact()",10000); } else { randomFact(); } }); function randomFact() { $("a.previous_button").css("display", "block"); $("a.next_button").css("display", "block"); position = Math.ceil(Math.random() * (facts.length - 1)); changeFact(0); } function changeFact(increment) { position = checkPosition(position, increment); $(".fun_facts_bg").css("background-image", "url(" + facts[position] + ")"); } <xsl:text disable-output-escaping="yes">&lt;!--//--&gt;&lt;![CDATA[//&gt;&lt;!-- function checkPosition(currentPos, increment) { currentPos = currentPos + increment; if (currentPos &gt; facts.length - 1) { currentPos = 1; } else if (currentPos &lt; 1) { currentPos = facts.length - 1; } return currentPos; } //--&gt;&lt;!]]&gt;</xsl:text> </script> <a class="previous_button" href="javascript:void(0);" onclick="changeFact(-1);"> <a class="next_button" href="javascript:void(0);" onclick="changeFact(1);">

  • Streaming content from (sharepoint) web part

    - by Mikko Rantanen
    How does one stream files, html or custom AJAX responses from web parts? Our current quick-and-very-dirty solution is to make the web part call the current page with certain query parameters, which the web part checks and instead of performing normal load it writes the required things to output and calls response end. This sounds bad since SharePoint might load other web parts and execute their code before reaching our web part. The web part is configured with data source settings which means the streaming context must be specific to the web part so it can acquire the correct data source settings.

  • Why does dojo parsing time depend on css and images availability?

    - by Kniganapolke
    I have been profiling javascript on my page that uses dojo widgets. I don't use explicit parsing - the parser runs on page load. What I noticed is that if I clear browser cache before refreshing the page, dojo parsing takes much more time than if all the files are already cached. Note that we build all the required dojo modules into a layer (a single file), so we don't lazy-load any js files. I wonder if dojo parsing process depends on images and css resources, as far as I know it only instantiates widgets and injects dom nodes. Do you have any ideas why dojo parser runs longer (2-3 times longer in my case) when the cache is cleared?

  • Balancing dependency injection with public API design

    - by kolektiv
    I've been contemplating how to balance testable design using dependency injection with providing simple fixed public API. My dilemma is: people would want to do something like var server = new Server(){ ... } and not have to worry about creating the many dependencies and graph of dependencies that a Server(,,,,,,) may have. While developing, I don't worry too much, as I use an IoC/DI framework to handle all that (I'm not using the lifecycle management aspects of any container, which would complicate things further). Now, the dependencies are unlikely to be re-implemented. Componentisation in this case is almost purely for testability (and decent design!) rather than creating seams for extension, etc. People will 99.999% of the time wish to use a default configuration. So. I could hardcode the dependencies. Don't want to do that, we lose our testing! I could provide a default constructor with hard-coded dependencies and one which takes dependencies. That's... messy, and likely to be confusing, but viable. I could make the dependency receiving constructor internal and make my unit tests a friend assembly (assuming C#), which tidies the public API but leaves a nasty hidden trap lurking for maintenance. Having two constructors which are implicitly connected rather than explicitly would be bad design in general in my book. At the moment that's about the least evil I can think of. Opinions? Wisdom?
