• JQuery: Live <a> tag partially working second time around.

  - by BPotocki

  I have the following jquery code: $("a[id*='Add_']").live('click', function() { //Get parentID to add to. var parentID = $(this).attr('id').substring(4); //Get div. var div = $("#CreateList"); //Ajax call to refresh "CreateList" div with new XML. div.load("/AddUnit?ParentID=" + parentID); }); Basically, contained within the div is a nested unordered list with several "Add_#" links. Clicking the links uses an ajax call to recreate the list with a new node. It clears all the add links, but they are added again by the ajax call. This is why I used the .live method so newly added "Add_#" links still have the binding. This works in most cases. If I click "Add_1", the div refreshes with the new info. If I then click "Add_2", it works again as expected. The problem I'm having happens when I click "Add_1", then the page refreshes (and creates a new "Add_1" link), then I click the re-rendered "Add_1" again. It's the same link, but it was refreshed during the ajax call. When I do that, the javascript function still gets called, but the .load method doesn't work. Any ideas why this might be happening? Thanks.

• Flash - can't access classes in another SWF

  - by Ashley Muller

  Hi, I'm trying to load a local SWF file and use the classes in that SWF (its a code only SWF, nothing in library). Here's the code that loads the library: var AD:ApplicationDomain = ApplicationDomain.currentDomain; var context:LoaderContext = new LoaderContext(false, AD); SA_gamecore_loader = new Loader(); SA_gamecore_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onGameCoreLibraryDataComplete); SA_gamecore_loader.load(new URLRequest("GameCore.swf"), context); Here's the code that tries to instantiate a class from GameCore.swf: var test:Class = GetClassFromDefinition("MenuArt") as Class; var testInstance:Object = new test(); public function GetClassFromDefinition(theStr:String):Object { var theClass:Object; try { theClass = GameCoreLibraryData.applicationDomain.getDefinition(theStr); } catch(e:ReferenceError) { trace(e); return null; } return theClass; } And this is the message that's traced: ReferenceError: Error #1065: Variable MenuArt is not defined. The GameCore.swf is in the same location as the parent swf. I'm using Flash Develop if that helps. Anyone able to point out what I'm doing wrong?

• Rails 2.3.5 table populated by fixtures at end of test run rather than at start

  - by rlandster

  I start with a test database containing the schema but with no data in the tables. I run a test like so cd test/ ruby unit/directive_test.rb I get failures indicating that the code found no data in the data tables. However, I look at the tables after running that test and the data is now in the the table. In fact, if I immediately run the test again I get no failures. So it appears that the fixture is being loaded into the table too late for one of my modules to find it. When are the fixtures loaded? After or before the app/model/*.rb files are executed? If it is after the models are executed is there a way to delay the loading? This issue is also relevant when running rake test:units since that task clears the test data after it finished.

• PHP, MySQL: Security concern; Page loads in a weird way

  - by Devner

  Hi all, I am testing the security of my website. I am using the following URL to load a PHP page in my website, on localhost: http://localhost/domain/user/index.php/apple.php When I do this, the page is not loading normally; Instead the images, icons used in the page simply vanish/disappear from the page. Only text appears. And also on any link I click on this page, it brings me to this same page again without navigating to the required page. So if I have hyperlinks to other pages, such as "SEARCH", which points to search.php, instead of navigating to the search.php page, it refreshes the index.php page and just appends the page name of the destination page to the end of the URL. For example, say I used the link above. It then loads the index.php page minus the images at it's will. When I click on the "Search" link to navigate to the search page, I see the following in the URL: http://localhost/domain/user/index.php/search.php I have a redirection configured to a 404 error page in my .htaccess file, but the page does not redirect to the 404 error page. Notice the search.php towards the end of the URL above. Any other link that I click, reloads the index.php page and just appends the destination page name to the end of the URL like I have shown above. I was expecting to see a 404 Error but that does not happen. The URL should not even be able to load the page because I do NOT have a "index.php" folder in my website. What can I do to solve this? All help is appreciated. Thank you.

• no instance of overloaded function getline c++

  - by Dave

  I'm a bit confused as to what i have incorrect with my script that is causing this error. I have a function which calls a fill for game settings but it doesn't like my getline. Also i should mention these are the files i have included for it: #include <fstream> #include <cctype> #include <map> #include <iostream> #include <string> #include <algorithm> #include <vector> using namespace std;' This is what i have: std::map<string, string> loadSettings(std::string file){ ifstream file(file); string line; std::map<string, string> config; while(std::getline(file, line)) { int pos = line.find('='); if(pos != string::npos) { string key = line.substr(0, pos); string value = line.substr(pos + 1); config[trim(key)] = trim(value); } } return (config); } The function is called like this from my main.cpp //load settings for game std::map<string, string> config = loadSettings("settings.txt"); //load theme for game std::map<string, string> theme = loadSettings("theme.txt"); Where did i go wrong ? Please help! The error: settings.h(61): error C2784: 'std::basic_istream<_Elem,_Traits> &std::getline(std::basic_istream<_Elem,_Traits> &&,std::basic_string<_Elem,_Traits,_Alloc> &)' : could not deduce template argument for 'std::basic_istream<_Elem,_Traits> &&' from 'std::string'

• Have something loaded only when JList item is visibile

  - by elvencode

  Hello, i'm implementing a Jlist populated with a lot of elements. Each element corresponds to a image so i'd like to show a resized preview of them inside each row of the list. I've implemented a custom ImageCellRenderer extending the Jlabel and on getListCellRendererComponent i create the thumbnail if there'snt any for that element. Each row corresponds to a Page class where i store the path of the image and the icon applied to the JLabel. Each Page object is put inside a DefaultListModel to populate the JList. The render code is something like this: public Component getListCellRendererComponent( JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) { Page page = (Page) value; if (page.getImgIcon() == null) { System.out.println(String.format("Creating thumbnail of %s", page.getImgFilename())); ImageIcon icon = new ImageIcon(page.getImgFilename()); int thumb_width = icon.getIconWidth() > icon.getIconHeight() ? 128 : ((icon.getIconWidth() * 128) / icon.getIconHeight()); int thumb_height = icon.getIconHeight() > icon.getIconWidth() ? 128 : ((icon.getIconHeight() * 128) / icon.getIconWidth()); icon.setImage(getScaledImage(icon.getImage(), thumb_width, thumb_height)); page.setImgIcon(icon); } setIcon(page.getImgIcon()); } I was thinking that only a certain item is visibile in the List the cell renderer is called but i'm seeing that all the thumnails are created when i add the Page object to the list model. I've tried to load the items and after set the model in the JList or set the model first and after starting appending the items but the results are the same. Is there any way to load the data only when necessary or do i need to create a custom control like a JScrollPanel with stacked items inside where i check myself the visibility of each elements? Thanks

• Image Upload directly from client to remote server? Spring/Tomcat

  - by Prem

  Just wondering what the common solution is for this. We have two web servers that are load balanced and a separate server that holds our images. Our current process is that a user uploads an image directly to the web server (which ever they are connected to) and we enter a job into our DB. Another process checks for image jobs every few mins and copies the image from the web server up to the image server. The delay from when a user uploads to when its visible is not ideal. We could tighten the loop on how often we check for image jobs but ideally I would like to have user uploaded images to go directly to the image server rather than copying twice. How should this be done? Is there anything in spring to deal with this ? Seems like how most would deal with a CDN i would think? I want to limit the time it takes for an image that a user uploads is available on our site...

• Javascript document.open asynchronous?

  - by Alex Schneider

  So on my site there is a Javascript function that will load a new site from the server via XMLHttpRequest. After that it replaces the current page with the new one: var post = new XMLHttpRequest(); post.open('POST', data); post.onload = function() { var do = document.open("text/html", "replace"); do.write(post.responseText); do.close(); goOn(); } function goOn() { console.log($('img:visible')); } Some could assume that after do.close() the document has changed and is ready. But it is not, e.g. if i load very much/big data/responseText the function goOn() only logs an empty result. Obviously goOn() gets in that case called before the DOM is ready to be read! Unfortunately the is no "ready" event fired after write() finished.... How can i be sure it is finished? /EDIT: goOn() logs this to Chrome Console: [prevObject: p.fn.p.init[1], context: #document, selector: "img:visible"] context: #document length: 0 prevObject: p.fn.p.init[1] selector: "img:visible" __proto__: Object[0] But if i right after that type $('img:visible') into console manually it shows me all images....

• Symbols (pdb) for native dll are not loaded due to post build step

  - by sean e

  I have a native release dll that is built with symbols. There is a post build step that modifies the dll. The post build step does some compression and probably appends some data. The pdb file is still valid however neither WinDbg nor Visual Studio 2008 will load the symbols for the dll after the post build step. What bits in either the pdb file or the dll do we need to modify to get either WinDbg or Visual Studio to load the symbols when it loads a dump in which our release dll is referenced? Is it filesize that matters? A checksum or hash? A timestamp? Modify the dump? or modify the pdb? modify the dll before it is shipped? (We know the pdb is valid because we are able to use it to manually get symbol names for addresses in dump callstacks that reference the released dll. It's just a total pain in the *ss do it by hand for every address in a callstack in all the threads.)

• Type of member is not CLS-compliant

  - by John Galt

  Using Visual Studio 2008 and VB.Net: I have a working web app that uses an ASMX web service which is compiled into its separate assembly. I have another class library project compiled as a separate assembly that serves as a proxy to this web service. This all seems to work at runtime but I am getting this warning at compile time which I don't understand and would like to fix: Type of member 'wsZipeee' is not CLS-compliant I have dozens of webforms in the main project that reference the proxy class with no compile time complaints as this snippet shows: Imports System.Data Partial Class frmZipeee Inherits System.Web.UI.Page Public wsZipeee As New ProxyZipeeeService.WSZipeee.Zipeee Dim dsStandardMsg As DataSet Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load And yet I have one webform (also in the root of the main project) which gives me the "not CLS-compliant" message but yet attempts to reference the proxy class just like the other ASPX files. I get the compile time warning on the line annoted by me with 'ERROR here.. Imports System.Data Partial Class frmHome Inherits System.Web.UI.Page Public wsZipeee As New ProxyZipeeeService.WSZipeee.Zipeee ERROR here Dim dsStandardMsg As DataSet Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load This makes no sense to me. The file with the warning is called frmHome.aspx.vb; all others in the project declare things the same way and have no warning. BTW, the webservice itself returns standard datatypes: integer, string, and dataset.

• sql server - framework 4 - IIS 7 weird sort from db to page

  - by ila

  I am experiencing a strange behavior when reading a resultset from database in a calling method. The sort of the rows is different from what the database should return. My farm: - database server: sql server 2008 on a WinServer 2008 64 bit - web server: a couple of load balanced WinServer 2008 64 bit running IIS 7 The application runs on a v4.0 app pool, set to enable 32bit applications Here's a description of the problem: - a stored procedure is called, that returns a resultset sorted on a particular column - I can see thru profiler the call to the SP, if I run the statement I see correct sorting - the calling page gets the results, and before any further elaboration logs the rows immediately after the SP execution - the results are in a completely different order (I cannot even understand if they are sorted in any way) Some details on the Stored Procedure: - it is called by code using a SqlDatAdapter - it has also an output value (a count of the rows) that is read correctly - which sort field is to be used is passed as a parameter - makes use of temp tables to collect data and perform the desired sort Any idea on what I could check? Same code and same database work correctly in a test environment, 32 bit and not load balanced.

• Jquery disable link for 5 seconds

  - by John

  I have this code: $('#page-refresh').click( function() { $.ajax({ url: "/page1.php", cache: false, dataType: "html", success: function(data) { $('#pagelist').html(data); } }); return false; }); In this code is it possible that on the ajax success function it disables the #page-refresh click for 5 seconds then re-enable it? Basically if a person clicks the button and this action happens I dont want them to click and run this action again for another 5 seconds. I looked at delay() to unbind the click for this then bind it again but once it unbinded it never allowed me to click the button anymore.

• Show content with fancybox like a Javascript Alert

  - by Ron Lens

  I try to show the content from a PHP-file in a fancybox but I can't handle it. Now it's the following situation: If a file permission problem occures a <div id="error"> is shown on the website. I'd like to have the content from <div id="error"> in fancybox. Everything I try I get the notice "The requested content cannot be loaded. Please try again later." That means the fancybox, it the file permission error occures, should be shown when the page is loading and not like usual shown when some events like click or mouseover. For example, if the error exists, the following content should be shown in the fancybox: <div style="width:100px; height:100px; background:#f00;"> <p>Failure</p> </div> This snippet is located in a file security_check.php. Now there are two possibilities. The 1st is to load the security_check.php directly into the fancybox or to put in the mentioned above snippet. So: how to load file contents into the fancybox?

• Catch hibernate exceptions with errorpage handler?

  I'm catching all exceptions within: java.lang.Throwable /page.xhtml java.lang.Error /page.xhtml But what If I get eg a hibernate ex: org.hibernate.exception.ConstraintViolationException Do I have to define error-pages for EVERY maybe occuring exception? Can't I just say "catch every exception"? Update Redirect on a 404 works.

• Sending emails with CodeIgniter in a local XAMPP server

  - by KeyStroke

  Hi, I'm trying to send emails through localhost (XAMPP Windows 1.7.3 installation), but I've been trying for hours with no success. This is the last code I tried: $config = Array( 'protocol' => 'smtp', 'smtp_host' => 'ssl://smtp.gmail.com', 'smtp_port' => 465, 'smtp_user' => '[email protected]', 'smtp_pass' => 'mypassword', ); $this->load->library('email', $config); $this->email->set_newline("\r\n"); $this->email->from('[email protected]', 'My Name'); $this->email->to('[email protected]'); $this->email->subject('Email Test'); $this->email->message('Testing the email class.'); if($this->email->send()) { echo 'Your email was sent.'; } else { show_error($this->email->print_debugger()); } Whenever I tried to load this the page shows that it's loading but nothing happens. Is there anything I need to setup in my server to insure email delivery? I messed with php.ini and sendmail's config a bit with no luck. And openSSL isn't available in case that matters. Any idea what's wrong?

• ReflectionTypeLoadException when I try to run Enable-Migrations with Entity Framework 5.0

  - by Eric Anastas

  I'm trying to use Entity Framework for the first time on one of my projects. I'm using the code first workflow to automatically create my database. Intitaly setting up the database worked fine. Now I'm trying to migrate changes in my classes into the database. The tutorial I'm reading says I need to run "Enable-Migrations" in the package manager console. Yet when I do this I get the following error PM> Enable-Migrations System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. at System.Reflection.RuntimeModule.GetTypes(RuntimeModule module) at System.Reflection.RuntimeModule.GetTypes() at System.Reflection.Assembly.GetTypes() at System.Data.Entity.Migrations.Design.ToolingFacade.BaseRunner.FindType[TBase](String typeName, Func`2 filter, Func`2 noType, Func`3 multipleTypes, Func`3 noTypeWithName, Func`3 multipleTypesWithName) at System.Data.Entity.Migrations.Design.ToolingFacade.GetContextTypeRunner.RunCore() at System.Data.Entity.Migrations.Design.ToolingFacade.BaseRunner.Run() Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. What am I doing wrong? How do I retrieve the loader exceptions property? Also NuGet says I have EF 5.0, but Version property of the EntityFramework item in my project references says 4.4.0.0. I'm not sure if this is related.

• Grails target folder doesn't appear to be on application's classpath

  - by Kobi

  I have a grails project with some additional java source files under src/java folder. When compiling/running the server, the files under that directory get compiled into the project's target folder, together with all other groovy/grails classes. So far so good. However, when I try to load one of the java source files (from src/java) using reflection (Class.forName to be exact), a ClassNotFoundException gets thrown. What is peculiar about the whole thing is that if I copy that same class from project's target/ folder into the following location (on windows): <myuser>\.grails\1.2.2\projects\<MyProjectName>\resources then no exception gets thrown and the corresponding class is loaded fine. This seems to indicate to me that the integrated grails server only looks at classes within the user's dynamically generated project folder, and not the actual project's target folder. Is my understanding correct? Is there a way to force grails to copy certain classfiles from target/ folder into the resources folder within the user dir? Is there a different way to load the classfiles using reflection? I was looking at using the grailsApplication's classloader but that didn't seem to work either. Any tips would be more than welcome. Thanks a lot in advance!

• Passing a Variable into jQuery AJAX

  - by Scott

  I'm stuck in a rut. I hope some one can help. Basically, I am building an AJAX mobile web app with jQuery. I am able to parse a specific XML file just fine, but I want the option to parse other XML files based on the link they were clicked on and load them on the fly into the same DIV or UL. So: click on Link1, loads XML1 click on Link2, loads XML2 I would like to be able to do this all client side, so no PHP (or is that a bad idea?). This the jquery code I've been using: $(document).ready(function() { $("a.load_ajax").click(loadAjax()); function loadAjax() { var fileID = get('?lineID='); var dataID = "xml/" + fileID + ".xml" $.ajax({ type: "GET", url: dataID, dataType: "xml", success: parseXml }); function parseXml(xml) { $(xml).find("train").each(function() { $("ul#ajax-output").append('<li>' + $(this).find("time").text() + '</li>'); }); } } }); Its just not working at all. I have been passing the variable using GET in the url. So the link in the HTML goes to /?lineID=SBD_to_Union and it should load the XML file called SBD_to_Union.xml Making sense to anyone? I'd appreciate some help.

  take this simple example A staff class which references other instances of the staff class public class Staff { public Staff() { Team = new List<Staff>(); } public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual IList<Staff> Team { get; set; } public virtual Staff Manager { get; set; } } The Fluent Mapping public class StaffMap : ClassMap<Staff> { public StaffMap() { Id(x => x.Id); Map(x => x.Name); References(x => x.Manager).Column("ManagerId"); HasMany(x => x.Team).KeyColumn("ManagerId").Inverse(); } } Now I want to run a query, which will load all the Staff and eager load the manager and Team members. This is what I came up with IList<Staff> resutls = session.CreateCriteria<Staff>() .SetFetchMode("Team", FetchMode.Eager) .SetResultTransformer(Transformers.DistinctRootEntity) .List<Staff>(); however the SQL (does what i want) has duplicate columns, 2 team2_.ManagerId and 2 team2_.Id SELECT this_.Id as Id0_1_, this_.Name as Name0_1_, this_.ManagerId as ManagerId0_1_, team2_.ManagerId as ManagerId3_, team2_.Id as Id3_, team2_.Id as Id0_0_, team2_.Name as Name0_0_, team2_.ManagerId as ManagerId0_0_ FROM [SelfRef].[dbo].[Staff] this_ left outer join [SelfRef].[dbo].[Staff] team2_ on this_.Id=team2_.ManagerId The question is, should this be happening? did i do something wrong in the query or map? or is it a feature of the HHib im using (which is Version 2.1.0.4000)? many thanks in advance

• How can I close a SimpleModal dialog when the user clicks the Back button?

  - by Wally Hartshorn

  When a user clicks on a button or link, I use the SimpleModal jQuery plugin to display a dialog to overlay the entire page, preventing the user from clicking another button or link during the delay before the next page loads. (I'd like to avoid this, but that's an issue for another day.) After the next page displays, if the user clicks the Back button, the previous page still has the SimpleModal overlay displayed, preventing them from using the page. This is a problem. How can I cause the SimpleModal dialog to close automatically either when the leaves the page or when the user clicks the Back button to return to the page? I tried this without success: $("body").unload(function() { $.modal.close(); }); Thanks! Wally

• CodeIgniter: Where should a particular functionality go ?

  - by Samnan

  I have an application in codeigniter and a page needs to perform the following tasks 1 - controller decides which model to use based of the url and parameters 2 - controller loads the model and get the data from it 3 - controller formats the data in a particular format, depending on the items in it 4 - controller loads a common view, which will display the data (formatted data contains simple display fields) now there is a search page, which needs to do a text query against all of the possible text fields in database in all tables. It needs to show each type of data in its own formatted output on a single page as a list. The problem: The search controller can do the search, dynamically load model for each record type, and get the data from model. Problem comes when the data needs to be formatted. It looks that ideally the search controller should load another controller which will provide formatted data ... There is where it gets out of control ... My question is: What am I doing wrong? Is there any better way to do this? How would you do the same to solve the problem?

  I am doing a little scripting and i find some more power would be nice. Like the ability to keep trying to delete a file with a 1sec delay AND have it portable since i spent some time today translating a bat script to bash. I know i can use php or python but i VERY MUCH PREFER static/compile time checking. Is there a way to run C# code as a script? I am hoping i dont have to create a custom ext and write a app to dynamically compile and execute the script (i know have source to compile .js somewhere...). Does anyone know of a solution?

• How to remove empty tables from a MySQL backup file.

  - by user280708

  I have multiple large MySQL backup files all from different DBs and having different schemas. I want to load the backups into our EDW but I don't want to load the empty tables. Right now I'm cutting out the empty tables using AWK on the backup files, but I'm wondering if there's a better way to do this. If anyone is interested, this is my AWK script: EDIT: I noticed today that this script has some problems, please beware if you want to actually try to use it. Your output may be WRONG... I will post my changes as I make them. # File: remove_empty_tables.awk # Copyright (c) Northwestern University, 2010 # http://edw.northwestern.edu /^--$/ { i = 0; line[++i] = $0; getline if ($0 ~ /-- Definition/) { inserts = 0; while ($0 !~ / ALTER TABLE .* ENABLE KEYS /) { # If we already have an insert: if (inserts > 0) print else { # If we found an INSERT statement, the table is NOT empty: if ($0 ~ /^INSERT /) { ++inserts # Dump the lines before the INSERT and then the INSERT: for (j = 1; j <= i; ++j) print line[j] i = 0 print $0 } # Otherwise we may yet find an insert, so save the line: else line[++i] = $0 } getline # go to the next line } line[++i] = $0; getline line[++i] = $0; getline if (inserts > 0) { for (j = 1; j <= i; ++j) print line[j] print $0 } next } else { print "--" } } { print }

• Determining selected state of jQuery Buttons

  - by lloydphillips

  I've got two radio buttons in a .net page which are being transformed to jQuery buttons a la http://jqueryui.com/demos/button/#radio When the page is loaded I have button 2 as checked. When clicking the buttons I'm firing the postback event. Problem is you can click on that button that is selected by default on the initial load i.e. Button 2, the postback is fired but the event handler isn't called in the .net code behind because the radio button is already classed as selected (and in normal circumstances wouldn't allow the postback to fire). To get around this I've added the e.PreventDefault() method BUT this is causing issues when Button 1 is clicked because before the click handler is called the button is set to selected. Therefore, in every case in the following code e.PreventDefault() is called: $(document).ready(function(){ $("[id*='rbPayable']").click(function(e){ if ($("[id*='rbPayable']").attr("checked")) e.preventDefault(); else setTimeout('__doPostBack(\'this.id\',\'\')', 0) }) $("[id*='rbReceivable']").click(function(e){ if ($("[id*='rbReceivable']").attr("checked")) e.preventDefault(); else setTimeout('__doPostBack(\'this.id\',\'\')', 0) }) }); What is the best way for me to load the page and effectively be able to do the following: 'If rbReceivable is checked then don't do anything otherwise do a postback.'

• Animate screen while loading textures

  - by Omega

  My RPG-like game has random battles. When the player enters a random battle, it is necessary for my game to load the textures used within that battle (animated monsters, animations, etc). The textures are quite a lot, and rather big (the battles are very graphical intensive). Such process consumes significant time. And while it is loading, the whole screen freezes. The game's map freezes, and the wait time is significant - I personally find it annoying. I can't afford to preload the textures because, after doing some math, I realized: If I preload all the textures at the beginning of the game, the application will definitely crash. If I preload the textures that are used in a specific map when the player enters the map, the application is very likely to crash as well. I can only afford to load the textures when I need them, and dispose of them as soon as the battle ends. I'd prefer to not use a "loading screen" image because it affects my game's design and concept. I want to avoid this approach. If I could do some kind of animation while loading the textures, it would be great, which leads to my question: is that possible? What kind of animation, you ask? Well, how about... you remember when Final Fantasy used to distort the screen while apparently loading the textures? Something like that. But well, distorting is quite a time-consuming process as well, so maybe just a cool frame-by-frame animation or something. While writing this, I realized that I could make small pauses between textures (there are multiple textures), and during such pauses, I update the screen to represent the animation's state. However, this is very unlikely to happen, because each texture is 2048x2048, so the animation would be refreshed at a rather laggy (and annoying) rate. I'd prefer to avoid this as well.
