  • loading javascript file after jquery.ready

    - by Spines
    I want to load a javascript file at the end of jquery.ready so that the code in my ready handler doesn't have to wait to execute until this large javascript file is loaded. My jquery.ready code doesn't rely on this javascript file at all. Would this be a good way to do that? $(function(){ ... ... $('head').append('<script type="text/javascript" src="/largejs.js"></script>'); });

  • Silverlight Isolated Storage and loading big files

    - by Thomas Joulin
    In a Windows Phone 7 application, I would like to query a big XML file (list of cities) stored using Isolated Storage. If I do that this way, will the file be loaded to memory ( 5 mo) ? If so, what other solution do I have? Edit: More details. I want to use AutoCompleteBox (http://www.jeff.wilcox.name/2008/10/introducing-autocompletebox/), but instead of using a web service (this is fixed data, no need to be online), I want to query a file/database/isolated storage... I have a fixed list of cities. I said in the comments it's 40k, but it finally seems closer to 1k rows.

  • Loading contents of TableView Controller after showing Tab

    - by Teo
    Hello, I have a 4 tabbar application. The second tab has a tableviewController. When i select the second tab the tableview is displayed with it's contents and it works fine. The problem is that that data is comming from the network and it talks 2-3 seconds to load. So when i press the second tab it goes there after the contents have been loaded. How can i show an empty tableview (i'll put an activity indicator) and then load and show the contents? Teo

  • How to do jquery code AFTER page loading?

    - by Alex
    If you want an event to work on your page, you should call it inside the $(document).ready() function. Everything inside it will load as soon as the DOM is loaded and before the page contents are loaded. I want to do javascript code only after the page contents are loaded how can I do that?

  • Dynamically loading modules in Python (+ multi processing question)

    - by morpheous
    I am writing a Python package which reads the list of modules (along with ancillary data) from a configuration file. I then want to iterate through each of the dynamically loaded modules and invoke a do_work() function in it which will spawn a new process, so that the code runs ASYNCHRONOUSLY in a separate process. At the moment, I am importing the list of all known modules at the beginning of my main script - this is a nasty hack I feel, and is not very flexible, as well as being a maintenance pain. This is the function that spawns the processes. I will like to modify it to dynamically load the module when it is encountered. The key in the dictionary is the name of the module containing the code: def do_work(work_info): for (worker, dataset) in work_info.items(): #import the module defined by variable worker here... # [Edit] NOT using threads anymore, want to spawn processes asynchronously here... #t = threading.Thread(target=worker.do_work, args=[dataset]) # I'll NOT dameonize since spawned children need to clean up on shutdown # Since the threads will be holding resources #t.daemon = True #t.start() Question 1 When I call the function in my script (as written above), I get the following error: AttributeError: 'str' object has no attribute 'do_work' Which makes sense, since the dictionary key is a string (name of the module to be imported). When I add the statement: import worker before spawning the thread, I get the error: ImportError: No module named worker This is strange, since the variable name rather than the value it holds are being used - when I print the variable, I get the value (as I expect) whats going on? Question 2 As I mentioned in the comments section, I realize that the do_work() function written in the spawned children needs to cleanup after itself. My understanding is to write a clean_up function that is called when do_work() has completed successfully, or an unhandled exception is caught - is there anything more I need to do to ensure resources don't leak or leave the OS in an unstable state? Question 3 If I comment out the t.daemon flag statement, will the code stil run ASYNCHRONOUSLY?. The work carried out by the spawned children are pretty intensive, and I don't want to have to be waiting for one child to finish before spawning another child. BTW, I am aware that threading in Python is in reality, a kind of time sharing/slicing - thats ok Lastly is there a better (more Pythonic) way of doing what I'm trying to do? [Edit] After reading a little more about Pythons GIL and the threading (ahem - hack) in Python, I think its best to use separate processes instead (at least IIUC, the script can take advantage of multiple processes if they are available), so I will be spawning new processes instead of threads. I have some sample code for spawning processes, but it is a bit trivial (using lambad functions). I would like to know how to expand it, so that it can deal with running functions in a loaded module (like I am doing above). This is a snippet of what I have: def do_mp_bench(): q = mp.Queue() # Not only thread safe, but "process safe" p1 = mp.Process(target=lambda: q.put(sum(range(10000000)))) p2 = mp.Process(target=lambda: q.put(sum(range(10000000)))) p1.start() p2.start() r1 = q.get() r2 = q.get() return r1 + r2 How may I modify this to process a dictionary of modules and run a do_work() function in each loaded module in a new process?

  • MVC - Loading DLL programmactically

    - by mikechats
    I'm trying to implement a plugable architecture in asp.net MVC. I have based my modules on the following article - http://www.wynia.org/wordpress/2008/12/aspnet-mvc-plugins. I have a DLL that contains a simple controller, and a view. The view is an embedded resource within the DLL. The problem I'm having is, if I drop the DLL in the bin directory of my MVC application manually, then everything works perfectly i.e. the assembly loads correctly. But when I copy the DLL from a file upload input box (via a web form) into the bin directoy, I get an error (The module was expected to contain an assembly manifest.) when trying to load the assembly. I use the same DLL, what could the problem be?

  • Greasemonkey - jQuery not loading

    - by Sid
    Hi, I tried to load a copy of jQuery 1.3.2 from jquery.com (because it seems 1.4.0+ aren't treated too well by GM) using @require. Even after I uninstall and reinstall the script, GM does not copy jquery-1.3.2.js to my gm_scripts folder like it should. Tried this almost 10 times today. Also, when I click on "Manage Scripts", it shows my script as running on * even though I've added @include for http://www.catholicon.in/* I'm using the latest updates on both FF 3.6 and GM 0.8 Thanks

  • Loading specific icon size into TIcon from stream (Delphi XE)

    - by moodforaday
    My application downloads and displays favicons for specific websites. I followed Bing's solution for detecting image format from stream, but have hit another snag. Assuming an actual icon image, the code goes like this: var icon : TIcon; begin icon := TIcon.Create; try icon.LoadFromStream( faviconStream ); spFavicon.Glyph.Assign( icon ); finally icon.Free; end; end; (spFavicon is TRzGlyphStatus from Raize Components. Its Glyph property is a TBitmap) Now, this works, but sometimes the downloaded icon contains multiple images in different sizes, e.g. 32x32 in addition to the expected 16x16. For some reason the control's Glyph property picks the larger size. How can I load only the 16x16 size into TIcon, or from TIcon into TBitmap? Test favicon: http://www.kpfa.org/favicon.ico On edit: If at all possible, I'd rather avoid saving the icon to a file first.

  • jQuery Address Plugin - Not allowing loading ajax?

    - by Nic Hubbard
    I am trying to test the jQuery Address Plugin and it seems to not allow ajax to work in the change function. I am using: $.address.change(function(event) { $('#content').load(event.value+' #content'); $.address.title(event.value); }); $('a').click(function() { $.address.value($(this).attr('href')); }); While I can use event.value for other things, it just does not seem to let the .load() function work. Even trying a static URL in .load() does nothing. Is something in the plugin preventing this? I thought this was the point of the plugin!

  • Loading and managing reference data in Rails

    - by jonnii
    Most of the apps I've worked on have had some kind of reference data stored in the database, for example categories, zipcodes, area codes etc... this is information that's going to change very infrequently. Most of the time you want to load some kind of display name, and that's it. Currently this isn't causing me too many headaches, it's easy to :include the models I need when doing my queries, but going forward it causes a lot of query noise. Ideally I'd like to load the reference data when the app starts and when referencing it in queries it'll load from the cache instead of going to the database. What's the best way to manage this?

  • preventing jCarousel form returning to begining position after loading page

    - by Crippletoe
    Hi all, i am using jCarousel as a menu in my website. there is a list of links there which is longer than its containing elements and jCarousel is used as a scroll bar to view that list. my problem is that whenever a link is clicked and a new page is loaded, jCarousel resets to its begining position thus sometimes an active link is no longer visible after the page reloads. any idea how i can make jCarousel focus on the specific active link? you can see an example of what i mean here: http://174.133.190.8/~goldarch/index.php?option=com_content&view=article&id=50&Itemid=57 (check out the menu on top) thank you all.

  • MATLAB - Delete elements of binary files without loading entire file

    - by Doresoom
    This may be a stupid question, but Google and MATLAB documentation have failed me. I have a rather large binary file (10 GB) that I need to open and delete the last forty million bytes or so. Is there a way to do this without reading the entire file to memory in chunks and printing it out to a new file? It took 6 hours to generate the file, so I'm cringing at the thought of re-reading the whole thing. EDIT: The file is 14,440,000,000 bytes in size. I need to chop it to 14,400,000,000.

  • Loading Modules in Angular

    - by SL Dev
    I'm new to AngularJS. In my efforts to learn, I've relied on the AngularJS tutorials. Now, I'm trying to build an app using the AngularSeed project template. I'm trying to make my project as modular as possible. For that reason, my controllers are broken out into several files. Currently, I have the following: /app index.html login.html home.html javascript app.js loginCtrl.js homeCtrl.js my app.js file has the following: 'use strict'; var app = angular.module('site', ['ngRoute']); app.config(function($routeProvider, $locationProvider) { $locationProvider.html5Mode(true); $routeProvider.when('/login', {templateUrl: 'app/login.html', controller:'loginCtrl'}); $routeProvider.when('/home', {templateUrl: 'app/home.html', controller:'homeCtrl'}); $routeProvider.otherwise({redirectTo: '/login'}); }); my loginCtrl.js file is very basic at the moment. It only has: 'use strict'; app.controller('loginCtrl', function loginCtrl($scope) { } ); My homeCtrl.js is almost the same, except for the name. It looks like the following: 'use strict'; app.controller('homeCtrl', function homeCtrl($scope) { } ); My index.html file is the angularSeed index-async.html file. However, when I load the dependencies, I have the following: // load all of the dependencies asynchronously. $script([ 'http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular.min.js', 'http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular-route.min.js', 'javascript/app.js', 'javascript/loginCtrl.js', 'javascript/homeCtrl.js' ], function() { // when all is done, execute bootstrap angular application angular.bootstrap(document, ['site']); }); My problem is, sometimes my app works and sometimes it doesn't. It's almost like something gets loaded before something else. Occasionally, I receive this error. Other times, I get an error in the console window that says: 'Uncaught ReferenceError: app is not defined' in loginCtrl.js. Sometimes it happens with homeCtrl.js. What am I doing wrong? It feels like I need to have my controllers in a module and pass that module in my app.config in the app.js file. However, a) I'm not sure if that allowed and b) I'm not sure how to do it.

  • Where should I put zoomIn in my MapActivity?

    - by Johny
    I'm writing an Android app, and I'd like to zoomIn as soon as the map has been loaded. I get the following error: java.lang.IllegalArgumentException: width and height must be > 0 This MapActivity - width and height must be > 0 question suggests the problem is the zoomIn() method is in the onCreate() method. But I get same error when I put it in the onResume() method. I've been searching for hours and I can't find anything about it at http://developer.android.com or anywhere else... Also I can't find a way to get the time point the map has been loaded. A "MapLoadedListener" or something like that...

  • Error when loading YAML config files in Rails

    - by ZelluX
    I am configuring Rails with MongoDB, and find a strange problem when paring config/mongo.yml file. config/mongo.yml is generated by executing script/rails generate mongo_mapper:config, and it looks like following: defaults: &defaults host: 127.0.0.1 port: 27017 development: <<: *defaults database: tc_web_development test: <<: *defaults database: tc_web_test From the config file we can see the objects development and test should both have a database field. But when it is parsed and loaded in config/initializers/mongo.db, config = YAML::load(File.read(Rails.root.join('config/mongo.yml'))) puts config.inspect MongoMapper.setup(config, Rails.env) the strange thing comes: the output of puts config.inspect is {"defaults"=>{"host"=>"127.0.0.1", "port"=>27017}, "development"=>{"host"=>"127.0.0.1", "port"=>27017}, "test"=>{"host"=>"127.0.0.1", "port"=>27017}} which does not contain database attribute. But when I execute the same statements in a plain ruby console, instead of using rails console, mongo.yml is parsed in a right way. {"defaults"=>{"host"=>"127.0.0.1", "port"=>27017}, "development"=>{"host"=>"127.0.0.1", "port"=>27017, "database"=>"tc_web_development"}, "test"=>{"host"=>"127.0.0.1", "port"=>27017, "database"=>"tc_web_test"}} I am wondering what may be the cause of this problem. Any ideas? Thanks.

  • iPhone - UITableViewController not loading table

    - by RyanJM
    I'm pushing a UITableViewController onto a navigationController. The title (set in the viewDidLoad) shows up but not the table. numberOfSectionsInTableView is called. But tableView:numberOfRowsInSection: is not called. I'm passing in 1 so it should be looking for number of rows. - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } I'm setting up the view in the following manner: SelectUserViewController *nextController = [[SelectUserViewController alloc] initWithStyle:UITableViewStyleGrouped]; nextController.managedObjectContext = managedObjectContext; OrangeQCAppDelegate *delegate = [[UIApplication sharedApplication] delegate]; [delegate.navigationController pushViewController:nextController animated:YES]; Again, the viewDidLoad method is called. And my class is set up as follows: @interface SelectUserViewController : UITableViewController <UITableViewDelegate, UITableViewDataSource> {...} What else should I be looking at? When I go through the debugger, after it looks at numberOfSectionsInTableView it just disappears (I think it is in the UITableViewController class) and never comes back.

  • Dynamic loading a class in java with a different package name

    - by C. Ross
    Is it possible to load a class in Java and 'fake' the package name/canonical name of a class? I tried doing this, the obvious way, but I get a "class name doesn't match" message in a ClassDefNotFoundException. The reason I'm doing this is I'm trying to load an API that was written in the default package so that I can use it directly without using reflection. The code will compile against the class in a folder structure representing the package and a package name import. ie: ./com/DefaultPackageClass.class // ... import com.DefaultPackageClass; import java.util.Vector; // ... My current code is as follows: public Class loadClass(String name) throws ClassNotFoundException { if(!CLASS_NAME.equals(name)) return super.loadClass(name); try { URL myUrl = new URL(fileUrl); URLConnection connection = myUrl.openConnection(); InputStream input = connection.getInputStream(); ByteArrayOutputStream buffer = new ByteArrayOutputStream(); int data = input.read(); while(data != -1){ buffer.write(data); data = input.read(); } input.close(); byte[] classData = buffer.toByteArray(); return defineClass(CLASS_NAME, classData, 0, classData.length); } catch (MalformedURLException e) { throw new UndeclaredThrowableException(e); } catch (IOException e) { throw new UndeclaredThrowableException(e); } }

  • Post Loading ads from Google Admanager

    - by Prem
    I have changed code around to basically load an add the bottom of the page in a hidden div and attached an onload event handler that called document.getElementById(xxx).appendChild() to take the hidden ad and move it into the right spot in my page. This works GREAT.. however when the ad is a text ad it AFTER i move the ad there is nothing in the rendered Iframe. I did tests to see what it looks like before i move it and sure enough the text links load in the IFRAME but the second i do the appendChild call to move the div that contains the ad i seem to loose the contents of the Iframe. Any ideas whats going on <div id="myad" style="display: none;"> GA_googleFillSlot("MyADSlotName"); </div> <script> window.onload = function() { // leader board document.getElementById('adplaceholder').appendChild(document.getElementById('myAd')); document.getElementById('myAd').style.display = ''; </script

  • AssemblyResolve event is not firing during compilation of a dynamic assembly for an aspx page.

    - by John
    This one is really pissing me off. Here goes: My goal is to load assemblies at run-time that contain embedded aspx,ascx etc. What I would also like is to not lock the assembly file on disk so I can update it at run-time without having to restart the application (I know this will leave the previous version(s) loaded). To that end I have written a virtual path provider that does the trick. I have subscribed to the CurrentDomain.AssemblyResolve event so as to redirect the framework to my assemblies. The problem is that the when the framework tries to compile the dynamic assembly for the aspx page I get the following: Compiler Error Message: CS0400: The type or namespace name 'Pages' could not be found in the global namespace (are you missing an assembly reference?) Source Error: public class app_resource_pages__version_1_0_0_0__culture_neutral__publickeytoken_null_default_aspx : global::Pages._Default, System.Web.SessionState.IRequiresSessionState, System.Web.IHttpHandle I noticed that if I load the assembly with Assembly.Load(AssemblyName) or Assembly.LoadFrom(filename) I dont get the above error. If I load it with Assembly.Load(byte[]) (so as to not lock it), the exception is thrown but my AssemblyResolve handler, when called is returning the assembly correctly (it is called once). So I am guessing that it is called once when the framework parses the asp markup but not when it tries to create the dynamic assembly for the aspx page.

  • Why is FLD1 loading NaN instead?

The interesting part of the disassembly is 0x080555b9 : neg %eax 0x080555bb : push %eax 0x080555bc : fildl (%esp) 0x080555bf : lea 0x4(%esp),%esp 0x080555c3 : fldl 0xfffffff0(%ebp) 0x080555c6 : fld1 0x080555c8 : faddp %st,%st(1) 0x080555ca : fxch %st(1) 0x080555cc : fstpl 0x8(%esp) 0x080555d0 : fstpl (%esp) 0x080555d3 : call 0x8051ce0 0x080555d8 : fmull 0xfffffff8(%ebp) While single-stepping through this function, gdb says (rate is 0.02, delay is 2; you can see them on the stack): (gdb) si 0x080555c6 30 return value * pow(1.+rate, -delay); (gdb) info float R7: Valid 0x4004a6c28f5c28f5c000 +41.68999999999999773 R6: Valid 0x4004e15c28f5c28f6000 +56.34000000000000341 R5: Valid 0x4004dceb851eb851e800 +55.22999999999999687 R4: Valid 0xc0008000000000000000 -2 =R3: Valid 0x3ff9a3d70a3d70a3d800 +0.02000000000000000042 R2: Valid 0x4004ff147ae147ae1800 +63.77000000000000313 R1: Valid 0x4004e17ae147ae147800 +56.36999999999999744 R0: Valid 0x4004efb851eb851eb800 +59.92999999999999972 Status Word: 0x1861 IE PE SF TOP: 3 Control Word: 0x037f IM DM ZM OM UM PM PC: Extended Precision (64-bits) RC: Round to nearest Tag Word: 0x0000 Instruction Pointer: 0x73:0x080555c3 Operand Pointer: 0x7b:0xbff41d78 Opcode: 0xdd45 And after the fld1: (gdb) si 0x080555c8 30 return value * pow(1.+rate, -delay); (gdb) info float R7: Valid 0x4004a6c28f5c28f5c000 +41.68999999999999773 R6: Valid 0x4004e15c28f5c28f6000 +56.34000000000000341 R5: Valid 0x4004dceb851eb851e800 +55.22999999999999687 R4: Valid 0xc0008000000000000000 -2 R3: Valid 0x3ff9a3d70a3d70a3d800 +0.02000000000000000042 =R2: Special 0xffffc000000000000000 Real Indefinite (QNaN) R1: Valid 0x4004e17ae147ae147800 +56.36999999999999744 R0: Valid 0x4004efb851eb851eb800 +59.92999999999999972 Status Word: 0x1261 IE PE SF C1 TOP: 2 Control Word: 0x037f IM DM ZM OM UM PM PC: Extended Precision (64-bits) RC: Round to nearest Tag Word: 0x0020 Instruction Pointer: 0x73:0x080555c6 Operand Pointer: 0x7b:0xbff41d78 Opcode: 0xd9e8 After this, everything goes to hell. Things get grossly over or undervalued, so even if there were no other bugs in my freeciv AI attempt, it would choose all the wrong strategies. Like sending the whole army to the arctic. (Sigh, if only I were getting that far.) I must be missing something obvious, or getting blinded by something, because I can't believe that fld1 should ever possibly fail. Even less that it should fail only after a handful of passes through this function. On earlier passes the FPU correctly loads 1 into ST(0). The bytes at 0x080555c6 definitely encode fld1 - checked with x/... on the running process. What gives?
