  • Android: ProgressDialog.show() crashes with getApplicationContext

    - by Felix
    I can't seem to grasp why this is happening. This code: mProgressDialog = ProgressDialog.show(this, "", getString(R.string.loading), true); works just fine. However, this code: mProgressDialog = ProgressDialog.show(getApplicationContext(), "", getString(R.string.loading), true); throws the following exception: W/WindowManager( 569): Attempted to add window with non-application token WindowToken{438bee58 token=null}.

  • Actionscript 3: Force program to wait until event handler is called

    - by Jeremy Swinarton
    I have an AS 3.0 class that loads a JSON file in using a URLRequest. package { import flash.display.MovieClip; import flash.display.Loader; import flash.net.URLRequest; import flash.net.URLLoader; import flash.events.Event; public class Tiles extends MovieClip { private var mapWidth:int,mapHeight:int; private var mapFile:String; private var mapLoaded:Boolean=false; public function Tiles(m:String) { init(m); } private function init(m:String):void { // Initiates the map arrays for later use. mapFile=m; // Load the map file in. var loader:URLLoader = new URLLoader(); loader.addEventListener(Event.COMPLETE, mapHandler); loader.load(new URLRequest("maps/" + mapFile)); } private function mapHandler(e:Event):void { mapLoaded=true; mapWidth=3000; } public function getMapWidth():int { if (mapLoaded) { return (mapWidth); } else { getMapWidth(); return(-1); } } } } When the file is finished loading, the mapHandler event makes changes to the class properties, which in turn are accessed using the getMapWidth function. However, if the getMapwidth function gets called before it finishes loading, the program will fail. How can I make the class wait to accept function calls until after the file is loaded?

  • DDD/NHibernate Use of Aggregate root and impact on web design - ex. Editing children of aggregate ro

    - by pbrophy
    Hopefully, this fictitious example will illustrate my problem: Suppose you are writing a system which tracks complaints for a software product, as well as many other attributes about the product. In this case the SoftwareProduct is our aggregate root and Complaints are entities that only can exist as a child of the product. In other words, if the software product is removed from the system, so shall the complaints. In the system, there is a dashboard like web page which displays many different aspects of a single SoftwareProduct. One section in the dashboard, displays a list of Complaints in a grid like fashion, showing only some very high level information for each complaint. When an admin type user chooses one of these complaints, they are directed to an edit screen which allows them to edit the detail of a single Complaint. The question is: what is the best way for the edit screen to retrieve the single Complaint, so that it can be displayed for editing purposes? Keep in mind we have already established the SoftwareProduct as an aggregate root, therefore direct access to a Complaint should not be allowed. Also, the system is using NHibernate, so eager loading is an option, but my understanding is that even if a single Complaint is eager loaded via the SoftwareProduct, as soon as the Complaints collection is accessed the rest of the collection is loaded. So, how do you get the single Complaint through the SoftwareProduct without incurring the overhead of loading the entire Complaints collection?

  • controller path not found for static images? asp.net mvc routing issue?

    - by rksprst
    I have an image folder stored at ~/Content/Images/ I am loading these images via <img src="/Content/Images/Image.png" /> Recently, the images aren't loading and I am getting the following errors in my error log.

  • Reloading an external element (via jQuery's .load) without impact on same-named host elements on sam

    - by Martin Pescador
    Hello together! [First, I'm an absolute beginner. I tried to express myself as good as I could - please correct me on any issue... Now: I have the following problem:] I am loading a div element, which class always is ".gallery" from a couple of pages (in this example "the page index.php?page=orange") into another page's div (in this case with the ID "orange") using the following code: $("#orange").load("http://example.com/index.php?page=orange .gallery"); Each div.gallery I load in, is a set of a few images. Between them, you can switch (there are "previous"- and "next"-links in ".imgnavi"). $(".imgnavi a").live("click", function(ev) { ev.preventDefault(); ev.stopPropagation(); $(".gallery").load($(this).attr("href")); return false; }) What happens now: Loading the different div.gallery into the new page is no problem, but as soon as I start to navigate inside those divs (each div is a little gallery, where you can switch between images), the div.gallery I am switching in is suddenly loaded into EVERY other div.gallery in the document! How do I prevent that?

  • jsf datatable lazy load filter and sorting

    - by darko petreski
    Hi, I have worked on several projects with a lot of data tables. The tables had sorting, filtering and paging of course on server side and with help of the db (all databases has implemented sording, filtering -where and limit the returned results). When workig on real application there are a thousands of even a millions rows. But I have seen several JSF dagatable components. They implement pagination, sorting and filtering on client side!! According to me this is very silly. This technology is called enterprise and they sort the data on the client side with java script! I have not seen any good JSF data grid that has build in features for sorting, filtering and lazy loading on the server side. Why is that? Am I looking in wrong direction or really there in no build support for this. Lately I am testing primefaces and lazy loading datatable. It really works fine, but the table i can only lazy load. If you add sort and filter then the problems begin. Conclusion: Is there any datatable JSF component than can perform lazy load pagination, and filtering and sorting on server side. If I need to implement my own solution thanks to the teams that made client side sorting and filtering, they are useless. Regards

  • Spoofing UserAgent in Opera

    - by PoweRoy
    I'm trying to spoof Opera (under linux) to be an other browser, in this case iPad for some testing purposes. Now I know sites can check which browser is accessing the using for example in PHP $useragent = $_SERVER['HTTP_USER_AGENT']; and in javascript navigator.userAgent (or navigator.platform). In firefox you can use an addon to easily switch your useragent and other relevant information, but in Opera it seems it bit hard to do. First in opera.ini you can do: [User Agent] Spoof UserAgent ID=1 But this is limited to a predefined list of UserAgents. No room for custom ones. Also in opera.ini [ISP] Id=iPad This will add iPad to the User Agent of Opera. It's a start and works most of the time on the sites. In opera.ini you can set a 'User JavaScript file' to load a custom JavaScript file before loading a website: [User Prefs] User JavaScript File=/opera_dir/userjs/load.js In load.js you can do: navigator.userAgent = "Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.10" Because this file gets executed before loading the website I can modify the UserAgent, but this won't work when a site is checking the UserAgent via PHP, but it works for sites checking with Javascript) So here's my question: is there another way of spoofing a complete custom UserAgent?

  • Custom UITableViewCell won't redraw on setNeedsDisplay

    - by Andrew Portner
    I created a custom UITableViewCell class with a UIButton, a UIImage, and two UILabels. The button and the image are overlayed on top of each other, and only one is displayed at a time. The expected behavior is you touch on the button, the button disappears, and it displays the image. The UITableViewCells are set to be reused. Here's my code: Constructor: - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier { if (self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]) { unheartButton = [[UIButton buttonWithType:UIButtonTypeCustom] retain]; unheartButton.backgroundColor = [UIColor clearColor]; unheartButton.frame = CGRectMake(10, 13, 20, 18); [unheartButton addTarget:self action:@selector(onButtonClick:) forControlEvents:UIControlEventTouchUpInside]; [unheartButton setBackgroundImage:[UIImage imageNamed:@"redheart.png"] forState:UIControlStateNormal]; imageView = [[UIImageView alloc] init]; imageView.frame = CGRectMake(12, 13, 16, 16); NSMutableArray *array = [[NSMutableArray alloc] init]; for (int ndx = 1; ndx < 13; ndx++) { [array addObject:[UIImage imageNamed:[NSString stringWithFormat:@"icon-loading-%d (dragged).tiff", ndx]]]; } imageView.animationImages = array; imageView.animationDuration = 1; imageView.hidden = YES; [array release]; [self.contentView addSubview:imageView]; [self.contentView addSubview:unheartButton]; return self; } } Button click: - (IBAction) onButtonClick: (id) sender { unheartButton.hidden = YES; imageView.hidden = NO; [imageView startAnimating]; [self setNeedsDisplay]; [self.contentView setNeedsDisplay]; [self.unheartButton setNeedsDisplay]; [self.imageView setNeedsDisplay]; } I'm calling setNeedsDisplay on everything, but nothing seems to happen. If I scroll off the screen and back up, the button is hidden and now the loading icon is shown, but this only happens after a scroll. I'm not sure what I need to do to get the cell to repaint.

  • Understanding the Silverlight Dispatcher

    - by Matt
    I had a Invalid Cross Thread access issue, but a little research and I managed to fix it by using the Dispatcher. Now in my app I have objects with lazy loading. I'd make an Async call using WCF and as usual I use the Dispatcher to update my objects DataContext, however it didn't work for this scenario. I did however find a solution here. Here's what I don't understand. In my UserControl I have code to call an Toggle method on my object. The call to this method is within a Dispatcher like so. Dispatcher.BeginInvoke( () => _CurrentPin.ToggleInfoPanel() ); As I mentioned before this was not enough to satisfy Silverlight. I had to make another Dispatcher call within my object. My object is NOT a UIElement, but a simple class that handles all its own loading/saving. So the problem was fixed by calling Deployment.Current.Dispatcher.BeginInvoke( () => dataContext.Detail = detail ); within my class. Why did I have to call the Dispatcher twice to achieve this? Shouldn't a high-level call be enough? Is there a difference between the Deployment.Current.Dispatcher and the Dispatcher in a UIElement?

  • AS3 "Loader" progress immediately goes to 100%

    - by Bart van Heukelom
    If you go to http://moederdagontbijtplacemat.nl/ you will see a progress bar. The application is loading a fairly large SWF from the server using the Loader class. Strangely enough, the progress bar immediately goes to 100% (but the loading still takes a while after that). The code is below, but you'll see it's basically too simple to break. It has worked when the application was on a different server, so I though maybe the new server wasn't sending the size of the large SWF in the http headers. Firebug does show a progress bar though, so that is not the case, the information should be available. It also works when I run the loader swf locally and change the URL (new URLRequest("Placemat.swf")) to the absolute URL of Placemat.swf on the server. var l:Loader = new Loader(); addChild(l); l.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, function(e:ProgressEvent) { s.setProgress(e.bytesLoaded/e.bytesTotal); trace(Math.round(100 * e.bytesLoaded/e.bytesTotal), "%"); }); l.contentLoaderInfo.addEventListener(Event.COMPLETE, function() { removeChild(s); }); l.load(new URLRequest("Placemat.swf"));

  • Creating generic list of instances of a class.

    - by Jim Branson
    I have several projects where I build a dictionary from a small class. I'm using C# 2008, Visual studio 2008 and .net 3.5 This is the code: namespace ReportsTest { class Junk { public static Dictionary<string, string> getPlatKeys() { Dictionary<string, string> retPlatKeys = new Dictionary<string, string>(); SqlConnection conn = new SqlConnection("Data Source=JB55LTARL;Initial Catalog=HldiReports;Integrated Security=True"); SqlDataReader Dr = null; conn.Open(); SqlCommand cmnd = new SqlCommand("SELECT Make, Series, RedesignYear, SeriesName FROM CompPlatformKeys", conn); Dr = cmnd.ExecuteReader(); while (Dr.Read()) { utypPlatKeys rec = new utypPlatKeys(Dr); retPlatKeys.Add(rec.Make + rec.Series + rec.RedesignYear, rec.SeriesName); } conn = null; Dr = null; return retPlatKeys; } } public class utypPlatKeys { public string Make { get; set; } public string Series { get; set; } public string RedesignYear { get; set; } public string SeriesName { get; set; } public utypPlatKeys(SqlDataReader dr) { this.Make = dr.GetInt16(dr.GetOrdinal("Make")).ToString("D3"); this.Series = dr.GetInt16(dr.GetOrdinal("Series")).ToString("D3"); this.RedesignYear = dr.GetInt16(dr.GetOrdinal("RedesignYear")).ToString(); this.SeriesName = dr["SeriesName"].ToString(); } } } The immediate window shows all of the entries in retPlatKeys and if you hover over retPlatKeys after loading it indicates the number of elements like this: "retPlatKeys| Count = 923 which is correct. I went to create a new project using this pattern only now the immediate window says retPlatKeys is out of scope and hovering over retPlatKeys after loading I get something like retPlatKeys|0x0000000002578900. Any help is greatly appreciated.

  • Fail to load NPAPI plugin in Google Chrome on Mac OS X

    - by Roman
    I have been trying to get Google Chrome (6.0.401.1 dev) on Mac OS X to load an NPAPI plugin without success so far. I have been working around the npsimple example from here: http://git.webvm.net/?p=npsimple. Using gcc on Mac and VC++ 2008 on Windows I managed to get it running on Safari and Firefox on Mac OS X and Firefox and Google Chrome on Windows, but not on Google Chrome on Mac OS X. When trying to debug Google Chrome on Mac OS X it seemed Google Chrome was briefly dyld-loading (and immediately dyld-unloading) the plugin on startup, but without actually looking-up any symbols within the plugin or calling any of the functions. It seemed to be doing that for every plugin, though. Also, when loading a page with the embed-tag for the plugin, Google Chrome did not seem to even dyld-load the plugin and no functions were called (not even NP_GetEntryPoints). Google Chrome also does not output any error message, it just simply does not load the plugin. I am not sure I caught everything with gdb because of Google Chrome using different processes, but I have also tried all the switches like --no-sandbox, --single-process and --plugin-startup-dialog (which incidentally does not seem to work at all on Mac OS X). I also made sure the architecture of the binary matches (i.e. 32-bit for Google Chrome). Has anybody had similar problems before? Is there anything I am missing here, like a gcc switch when compiling or something? Any help would be greatly appreciated.

  • JNI problem when calling a native library that loads another native library

    - by TheEnemyOfQuality
    I've got a bit of an odd problem. I have a project in C++ that's basically a wrapper for a third party DLL like this: MyLibrary --loads DLL_A ----loads DLL_B I load DLL_A with LoadLibrary(), wrap several of its functions and generate my own DLL. I've tested this in a C++ project and a C# project. Both do everything they're supposed to do: load DLL_A, make a couple of function calls, and indirectly load DLL_B. The problem is when I build a DLL for java and make the calls through JNI. Everything runs like it should (no java.lang.UnsatisfiedLinkError), but when it comes time for DLL_A to load DLL_B it doesn't work. From debugging, the loading of DLL_B happens on a function call in DLL_A that takes a callback. When called from Java, this function call seems to fail (the function pointer is fine and the actual call goes off without a hitch), and I get an odd pop-up window saying DLL_B failed to load, and my program is left waiting for a callback that never happens. I can explicitly load DLL_B just fine (both from Java and from C++) and I've checked every possible path, path variable, and tried placing the dlls everywhere to see if it could be looking somewhere funny. I'm pretty sure it's not a path problem. Ultimately I don't know how DLL_A is loading DLL_B and I can't figure out why everything works fine in C++ and C#, but not in Java. I'm absolutely flummoxed. It could still be something specific to my setup (although I've looked as hard as I can look), but I'm throwing this scenario out there to see if anyone has run into a similar problem. -Dave

  • Proper way to cleanup dynamic engines and can they be loaded twice?

    - by Becky
    Hello - I am having problems loading Engine PKCS #11 as a dynamic engine using python and M2Crypto. I am trying to access an Aladdin USB eToken. Here are the important steps from my python code: dynamic = Engine.load_dynamic_engine("pkcs11", "/usr/local/ssl/lib/engines/engine_pkcs11.so") pkcs11 = Engine.Engine("pkcs11") pkcs11.ctrl_cmd_string("MODULE_PATH", "/usr/lib/libeTPkcs11.so") pkcs11.engine_init_custom() # initialize engine with custom M2Crypto patch # next few steps which I deleted pass password and grab key & cert off token Engine.cleanup() This works fine the first time this method gets run. The second time, it fails when loading the dynamic engine (see error below). Traceback (most recent call last): File "", line 1, in ?

  • c# opennetCF background worker stops after 100 iterations

    Hi. I have a background worker that stops after 100 iterations. Like this: BackgroundWorker bgWorker = new BackgroundWorker(); bgWorker.WorkerReportsProgress = true; bgWorker.WorkerSupportsCancellation = true; bgWorker.DoWork += new OpenNETCF.ComponentModel.DoWorkEventHandler(this.bgWorker_DoWork); bgWorker.RunWorkerCompleted += new OpenNETCF.ComponentModel.RunWorkerCompletedEventHandler(this.bgWorker_RunWorkerCompleted); bgWorker.ProgressChanged += new OpenNETCF.ComponentModel.ProgressChangedEventHandler(this.bgWorker_ProgressChanged); private void bgWorker_DoWork(object sender, DoWorkEventArgs e) { for(i=0; i<300; i++) { bgWorker.ReportProgress(i, i); } } private void bgWorker_ProgressChanged(object sender, ProgressChangedEventArgs e) { this.labelProgress.Text = e.UserState.ToString(); } private void bgWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { MessageBox.Show("finished loading..."); } What happens is that the labelProgress' value stops at 100, and the messagebox pops up and says "finished loading...". Anybody have an idea of what is wrong. Why does the thread stop at the 101 iteration? Thanks in advance.

  • How to use an OSGi service from a web application?

    - by Jaime Soriano
    I'm trying to develop a web application that is going to be launched from a HTTP OSGi service, this application needs to use other OSGi service (db4o OSGi), for what I need a reference to a BundleContext. I have tried two different approaches to get the OSGi context in the web application: Store the BundleContext of the Activator in an static field of a class that the web service can import and use. Use FrameworkUtil.getBundle(this.getClass()).getBundleContext() (being this an instance of MainPage, a class of the web application). I think that first option is completely wrong, but anyway I'm having problems with the class loaders in both options. In the second one it raises a LinkageError: java.lang.LinkageError: loader constraint violation: loader (instance of org/apache/felix/framework/ModuleImpl$ModuleClassLoader) previously initiated loading for a different type with name "com/db4o/ObjectContainer" Also tried with Equinox and I have a similar error: java.lang.LinkageError: loader constraint violation: loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) previously initiated loading for a different type with name "com/db4o/ObjectContainer" The code that provokes the exception is: ServiceReference reference = context.getServiceReference(Db4oService.class.getName()); Db4oService service = (Db4oService)context.getService(reference); database = service.openFile("foo.db"); The exception is raised in the last line, database class is ObjectContainer, if I change the type of this variable to Object exception is not raised, but It's not useful as an Object :)

  • How to use 3rd party libraries in glassfish?

    - by Hank
    I need to connect to a MongoDB instance from my EJB3 application, running on glassfish 3.0.1. The Mongo project provides a set of drivers, and I'm able to use them in a standalone Java application. How would I use them in a JEE application? Or maybe better phrasing: how would I make a 3rd party library available to my application when it runs in an EJB container? At the moment, I'm getting a java.lang.NoClassDefFoundError when deploying a bean that tries to import from the library: [#|2010-03-24T11:42:15.164+0100|SEVERE|glassfishv3.0|global|_ThreadID=28;_ThreadName=Thread-1;|Class [ com/mongodb/DBObject ] not found.

Do I need to 'register' the library with the container? Reference it via Annotation? Extend the classpath of the container to include the library?

  • Problems with Merb on Snow Leopard

    - by hamhoagie
    I've recently started looking at Merb, for use with some small projects around the office. I'm trying to set up my first project following the docs, and am encountering an exception such as: foo:beta user$ merb Merb root at: /Users/user/code/merb/beta Loading init file from ./config/init.rb Loading ./config/environments/development.rb ~ Connecting to database... ~ Loaded slice 'MerbAuthSlicePassword' ... ~ Parent pid: 39794 ~ Compiling routes... ~ Activating slice 'MerbAuthSlicePassword' ... ~ ~ FATAL: Mongrel is not installed, but you are trying to use it. You need to either install mongrel or a different Ruby web server, like thin. I have installed Mongrel from gem as well as from MacPorts, and am confused by this exception.

Thanks in advance.

  • Making Spring Data JPA work with DataNucleus (GAE) (Spring Boot)

    - by xybrek
    There are several hints that Spring Data works with Google App Engine like: http://tommysiu.blogspot.com/2014/01/spring-data-on-gae-part-1.html http://blog.eisele.net/2009/07/spring-300m3-on-google-appengine-with.html Much of the examples are not "Spring Boot" so I've been trying to retrofit things with it.

The problem is the "wiring" up with the Spring Data JPA, can anybody help?

  • YUI: ensuring DOM elements and scripts are ready

    - by dound
    If I put my inline script after the DOM elements it interacts with, should I still use YUI 3's domready event? I haven't noticed any problems, and it seems like I can count on the browser loading the page sequentially. (I already use YUI().use('node', ... to make sure the YUI functions I need have been loaded since the YUI script is a separate file.) Is there a way to speed up the loading of widgets like YUI 2's calendar? I load the appropriate script in <head> element of my page. I use YUI().use('yui2-calendar', ... to make sure the Calendar widget is available. Unfortunately, this causes a short but noticeable delay when I load my page with the calendar. If I omit the YUI().use('yui2-calendar', ... code then it shows up without a noticeable delay - but I guess this could cause the Calendar to not show up at all if the YUI script doesn't load in time? With regards to #2, is it possible to reduce the visual artifact of the calendar not being present and then showing up? I've made it slightly better by specifying a height and width for the parent div so that at least the space is already allocated = minimal shifting around when it does load.
