How is jQuery so fast?

- by ClarkeyBoy

Hey, I have a rather large application which, on the admin frontend, takes a few seconds to load a page because of all the pageviews that it has to load into objects before displaying anything. Its a bit complex to explain how the system works, but a few of my other questions explains the system in great detail. The main difference between what they say and the current system is that the customer frontend no longer loads all the pageviews into objects when a customer first views the page - it simply adds the pageview to the database and creates an object in an unsynchronised list... to put it simply, when a customer views a page it no longer loads all the pageviews into objects; but the admin frontend still does. I have been working on some admin tools on the customer frontend recently, so if an administrator clicks the description of an item in the catalogue then the right hand column will display statistics and available actions for the selected item. To do this the page which gets loaded (through $('action-container').load(bla bla bla);) into the right hand column has to loop through ALL the pageviews - this ultimately means that ALL the pageviews are loaded into objects if they haven't been already. For some reason this loads really REALLY fast. The difference in speed is only like a second on my dev site, but the live site has thousands of pageviews so the difference is quite big... So my question is: why is it that the admin frontend loads so slowly while using $(bla).load(bla); is so fast? I mean whatever method jQuery uses, can't browsers use this method too and load pages super-fast? Obviously not as someone would've done that by now - but I am interested to know just why the difference is so big... is it just my system or is there a major difference in speed between the browser getting a page and jQuery getting a page? Do other people experience the same kind of differences? Thanks in advance, Regards, Richard

jQuery/Ajax with Zend Framework

- by Nathan

I've been tinkering around with Zend-Framework and Jquery for a month or so, and finally started tinkering with them together using ZendX_JQuery. It seems I've ran into something that at first seemed it should be simple, So maybe I'm just missing something here. I have a view along the lines of: $this->ajaxLink( $this->escape($var->title), $this->baseUrl() . "/another/action", array('update' => '#domain' . $var->id , 'complete' => '$("#domain' . $var->id .'").toggle("slow");')); echo '<div id="domain"' . $var->id . '" style="display:none;" ></div>'; Which works correctly, when the link displayed by the code above is clicked it loads the contents returned from /another/action into the domain"id" div. The problem occurs when the view loaded by the above contains an ajaxLink() the ajax link stops working. This can be fixed by adding an option to the ajaxLink() array "inline" = true but what if I need other JQuery views helpers to work when loaded into the page via ajax i.e. dialogContainer() I guess I could simply be asking how to control where zendx jquery helper puts java script. by default it is trying to put all statments in the <head> section in a single <script> tag. I need away around that for views displayed from an ajax call. Does Dojo try and force all php rendered javascript/ajax into the head also? Thanks.

Django model operating on a queryset

- by jmoz

I'm new to Django and somewhat to Python as well. I'm trying to find the idiomatic way to loop over a queryset and set a variable on each model. Basically my model depends on a value from an api, and a model method must multiply one of it's attribs by this api value to get an up-to-date correct value. At the moment I am doing it in the view and it works, but I'm not sure it's the correct way to achieve what I want. I have to replicate this looping elsewhere. Is there a way I can encapsulate the looping logic into a queryset method so it can be used in multiple places? I have this atm (I am using django-rest-framework): class FooViewSet(viewsets.ModelViewSet): model = Foo serializer_class = FooSerializer bar = # some call to an api def get_queryset(self): # Dynamically set the bar variable on each instance! foos = Foo.objects.filter(baz__pk=1).order_by('date') for item in foos: item.needs_bar = self.bar return items I would think something like so would be better: def get_queryset(self): bar = # some call to an api # Dynamically set the bar variable on each instance! return Foo.objects.filter(baz__pk=1).order_by('date').set_bar(bar) I'm thinking the api hit should be in the controller and then injected to instances of the model, but I'm not sure how you do this. I've been looking around querysets and managers but still can't figure it out nor decided if it's the best method to achieve what I want. Can anyone suggest the correct way to model this with django? Thanks.

UIWebViewDelegate returns different error message on iPod Touch 2G and 3G

- by lostInTransit

Hi I have an app developed using SDK 3.0. My view has a UIWebView whose delegate is the viewcontroller. I want to show an error message when the webview does not load (in case the touch goes out of wifi range or wifi is turned off) I override this method to show an alert - (void)webView:(UIWebView *)wbView didFailLoadWithError:(NSError *)error But this caused an issue when some links were clicked on the webview. The page loaded but if some images from the previous page were not loaded, the method call was triggered. Testing on an iPod Touch 3G, the NSError's userInfo has the localized description as no Internet connection if load fails due to no internet connection. But this only seems to be true for an iPod Touch 3G. 2G shows a different message (I got to know from some beta testers. They aren't very technical so can't tell them to get me the logs or anything.) Can anyone with an iPod Touch 2G tell me the values for the NSError userInfo? Or better still, did anyone else face this issue? How did you resolve it? Thanks.

Amazon S3 and swfaddress

- by justinbach

I recently migrated a large AS3 site (lots of swfs, lots of flvs) to Amazon S3. Pretty much everything but HTML and JS files is being stored/served from Amazon, and it's working well. The only problem I'm having is that I built the site using SWFaddress (actually, via the Gaia framework which uses SWFaddress), and for some reason, SWFaddress is no longer updating the address bar correctly as users navigate from page to page. In other words, the URL persistently remains http://www.mysite.com, not http://www.mysite.com/#/section as would be the case were SWFaddress functioning correctly (and as it was functioning prior to the migration). Stranger yet, if I go to (e.g.) http://www.mysite.com/#/section directly, the deeplinking functions as you'd expect--I arrive directly at the correct section. However, navigating away from that section doesn't have any effect on the address bar, despite the fact that it should be dynamically updated. I've got a crossdomain.xml file set up on the site that allows access from all domains, so that's not the issue, and I don't know what else might be. Any ideas would be greatly appreciated! P.S. I integrated S3 by putting pretty much the entire site in an S3 bucket and then just changing the initial swfobject embed to point to the S3 instance of main.swf, passing in the S3 path as the "base" param to the embedded swf so that all dynamically loaded assets and swfs would also be sourced from s3. Dunno if that's related to the troubles I'm having.

Python: Class factory using user input as class names

- by Sano98

Hi everyone, I want to add class atttributes to a superclass dynamically. Furthermore, I want to create classes that inherit from this superclass dynamically, and the name of those subclasses should depend on user input. There is a superclass "Unit", to which I can add attributes at runtime. This already works. def add_attr (cls, name, value): setattr(cls, name, value) class Unit(object): pass class Archer(Unit): pass myArcher = Archer() add_attr(Unit, 'strength', 5) print "Strenght ofmyarcher: " + str(myArcher.strength) Archer.strength = 2 print "Strenght ofmyarcher: " + str(myArcher.strength) This leads to the desired output: Strenght ofmyarcher: 5 Strenght ofmyarcher: 2 But now I don't want to predefine the subclass Archer, but I'd rather let the user decide how to call this subclass. I've tried something like this: class Meta(type, subclassname): def __new__(cls, subclassname, bases, dct): return type.__new__(cls, subclassname, Unit, dct) factory = Meta() factory.__new__("Soldier") but no luck. I guess I haven't really understood what new does here. What I want as a result here is class Soldier(Unit): pass being created by the factory. And if I call the factory with the argument "Knight", I'd like a class Knight, subclass of Unit, to be created. Any ideas? Many thanks in advance! Bye -Sano

How do I 'addChild' an DisplayObject3d from another class? (Papervision3d)

- by Sandor

Hi All Im kind of new in the whole papervision scene. For a school assignment I'm making a panorama version of my own room using a cube with 6 pictures in it. It created the panorama, it works great. But now I want to add clickable objects in it. One of the requirements is that my code is OOP focused. So that's what I am trying right now. Currently I got two classes - Main.as (Here i make the panorama cube as the room) - photoWall.as (Here I want to create my first clickable object) Now my problem is: I want to addChild a clickable object from photoWall.as to my panorama room. But he doesn't show it? I think it has something to do with the scenes. I use a new scene in Main.as and in photoWall.as. No errors or warnings are reported This is the piece in photoWall.as were I want to addChild my object (photoList): private function portret():void { //defining my material for the clickable portret var material : BitmapFileMaterial = new BitmapFileMaterial('images/room.jpg'); var material_list : MaterialsList = new MaterialsList( { front: material, back: material } ); // I don't know if this is nessecary? that's my problem scene = new Scene3D(); material.interactive = true; // make the clickable object as a cube var photoList : DisplayObject3D = new Cube(material_list, 1400, 1400, 1750, 1, 4, 4, 4); // positioning photoList.x = -1400; photoList.y = -280; photoList.z = 5000; //mouse event photoList.addEventListener( InteractiveScene3DEvent.OBJECT_CLICK, onPress); // this is my problem! I cannot see 'photoList' within my scene!!! scene.addChild(photoList); // trace works, so the function must be loaded. trace('function loaded'); } Hope you guys can help me out here. Would really be great! Thanks, Sandor

jquery - radio button not checked on page load, but checked on same function call later

- by Bill Zimmerman

Hi, I'm having a strange problem with jquery. When my page loads, I dynamically create some simple radio buttons in a special i've created. However, the default radio button is not checked. It is checked however when the change() event is triggered later, but is never checked the first time. Can someone help? I am certain that the change() event is triggered on the page load, because the rest of the HTML is added dynamically and I can see it. The basic idea is when the page loads, I bind an event handler, and then immediately call it to make sure that the default options are loaded. $(document).ready(function() { $(".options select[name=App]").change(onAppChange); //trigger the change function in the dropdown to populate default options $(".options select[name=App]").change() } Here is the simple onAppChange() function: function onAppChange() { var val = $(this).val(); var app_options = $(this).closest(".options").find(".app_options"); //clear the app_options app_options.empty(); var newOptions = ''; switch(val) { case 'testapp': newOptions='\ <fieldset>\ <legend>TestApp</legend>\ Option 1:\ <label>\ <input type="radio" name="option1" value="value1" checked>\ Value1\ </label>\ \ <label>\ <input type="radio" name="option1" value="value2">\ value2\ </label>\ \ </fieldset>'; break; case 'todo': //for testing newOptions='FOO'; break; } app_options.append(newOptions); } Yes, I am aware that I could use javascript to automatically select a radio button again, but I asked this question because I wanted to understand why this is happening. When using and , there doesn't seem to be any problem. Only with radio buttons. Why does the behavior differ when the same change() event is triggered? What is going on behind the scenes?

Gems install fine but don't show as installed under rake gems

I'll show you my output here: rake gems (in /Users/jp/Sites/central/trunk) - [F] authlogic - [R] activesupport - [F] builder - [F] formtastic - [R] activesupport >= 2.3.0 - [R] actionpack >= 2.3.0 - [ ] fastercsv I = Installed F = Frozen R = Framework (loaded before rails starts) Making sure fastercsv is installed: gem which fastercsv /usr/local/lib/ruby/gems/1.8/gems/fastercsv-1.5.3/lib/fastercsv.rb After installing through a variety of methods but only one is shown here: sudo rake gems:install (in /Users/jp/central/trunk) gem install fastercsv Successfully installed fastercsv-1.5.3 1 gem installed Installing ri documentation for fastercsv-1.5.3... Installing RDoc documentation for fastercsv-1.5.3...

Another thing is that I really tried to figure this out. There's a bunch of people saying clean up local gems in your user account, always install with sudo, etc. But I've tried all that. What would you guys do to fix this? Thanks many times over, Josh

iPhone Landscape FAQ and Solutions

- by Johannes Rudolph

There has been a lot of confusion and a set of corresponding set of questions here on SO how iPhone applications with proper handling for Landscape/Portrait mode autorotation can be implemented. It is especially difficult to implement such an application when starting in landscape mode is desired. The most common observed effect are scrambled layouts and areas of the screen where touches are no longer recognized. A simple search for questions tagged iphone and landscape reveals these issues, which occur under certain scenarios: Landscape only iPhone app with multiple nibs: App started in Landscape mode, view from first nib is rendered fine, everything view loaded from a different nib is not displayed correctly. Iphone Landscape mode switching to Portraite mode on loading new controller: Self explanatory iPhone: In landscape-only, after first addSubview, UITableViewController doesn’t rotate properly: Same issue as above. iPhone Landscape-Only Utility-Template Application: Layout errors, controller does not seem to recognize the view should be rotated but displays a clipped portrait view in landscape mode, causing half of the screen to stay blank. presentModalViewController in landscape after portrait viewController: Modal views are not correctly rendered either. A set of different solutions have been presented, some of them including completely custom animation via CoreGraphics, while others build on the observation that the first view controller loaded from the main nib is always displayed correct. I have spent a significant amount of time investigating this issue and finally found a solution that is not only a partial solution but should work under all these circumstances. It is my intend with this CW post to provide sort of a FAQ for others having issues with UIViewControllers in Landscape mode. Please provide feedback and help improve the quality of this Post by incorporating any related observations. Feel free to edit and post other/better answers if you know of any.

dlopen / dlsym with as little linking as possible

- by johannes

I have an application which can make use of plugins which are loaded at runtime using dlopen. Each of the plugins defines a function toretrieve the plugin information which is defined using a common structure. Something like that: struct plugin { char *name; char *app_version; int app_verion_id; char *plugin_version; int plugin_version_id; /* ... */ }; struct plugin p = { "sample plugin",APP_VERION,APP_VERSION_ID,"1.2.3",10203 }; struct plugin *get_plugin() { return &p; } This works well and plugins can be loaded. Now i want to build a small tool to read these properties without linking the whole application. For doing that I have some code like this: void *handle; struct plugin *plugin; struct plugin *(get_plugin*)(); handle = dlopen(filename, RTLD_LAZY); if (!handle) { /*...return; ...*/ } get_plugin = dlym(handle, "get_plugin"); if (!get_plugin) { /*...return; ...*/ } plugin = get_plugin(); printf("Plugin: %s\n", plugin->name); This works nice for simple plugins. The issue is that many plugins reference further symbols from the application, which are resolved even though RTLD_LAZY was set. (like global variables from the application which are used to initialize plugin-global things) So the dlopen() call fails with an error like fatal: relocation error: file sample_plugin.so: symbol application_some_symbol: referenced symbol not found. As I just want to have access to the single simple structure I was wondering how I can prevent the linker from doing that much of his work.

jQuery eval of ajax inline script not throwing errors

- by Josh

http://stackoverflow.com/questions/606794/debugging-ajax-code-with-firebug This question is quite similar, though old and without real answers. I'm currently putting together an app that has scripts that get loaded in with an ajax request. An example: var main = _main.get(); main.load( someurl ); Where someurl is a page that contains an inline script element: <script type="text/javascript"> $(document).ready( function(){ var activities = new activities(); activities.init(); }); </script> jQuery will do a line by line eval of js that lives in inline script tags. The problem is, I get no errors or any information whatsoever in firebug when something goes awry. Does anyone have a good solution for this? Or a better practice for loading pages which contain javascript functionality? Edit: A little progress... so at the top of the page that is being loaded in via ajax, I have another script that was being included like this: <script type="text/javascript" src="javascript/pages/activities.js"></script> When I moved the inline $(document).ready() code in the page to the end of this included file, instead, syntax errors were now properly getting thrown. As an aside, I threw a console.log() into the inline script tag, and it was being logged just fine. I also tried removing the $(document).ready() altogether, and also switching it out for a $(window).load() event. No difference. May have something to do with the inline scripts dependency on the included activities.js, I guess. :: shakes head :: javascript can be a nightmare.

WPF: How do I get a reference to a styled window control in code behind?

- by Brad

I have a window defined with a style: <Window x:Class="winBorderless" x:Name="winBorderless" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Local="clr-namespace:WindowStyle" Style="{StaticResource Window_Cartesia}" WindowStartupLocation="CenterScreen" BorderThickness="1" BorderBrush="#FF9CAAC1" Margin="5" Title="[Document Title]"> and the style defined in an application level dictionary: <Style x:Key="Window_Cartesia" TargetType="{x:Type Window}"> <Setter Property="WindowStyle" Value="None"/> <Setter Property="AllowsTransparency" Value="True"/> <Setter Property="Background" Value="Transparent"/> <EventSetter Event="Loaded" Handler="Loaded"/> <EventSetter Event="PreviewKeyDown" Handler="Preview_KeyDown"/> <EventSetter Event="MouseMove" Handler="FullScreen_MouseMove"/> <Setter Property="Template"> In code behind I have a reference to the Window instance set: Win = DirectCast(sender, winBorderless) This allows access to the window properties as the EventSetters pass references to the various controls. However, it doesn't provide for access to the controls defined in the style through the window reference as they don't exist there. So, what is the best way to reference a control through code behind that is defined in the style. I'd prefer not to iterate the trees to find them but ya gotta do....

What does stdole.dll do?

- by rc1

We have a large C# (.net 2.0) app which uses our own C++ COM component and a 3rd party fingerprint scanner library also accessed via COM. We ran into an issue where in production some events from the fingerprint library do not get fired into the C# app, although events from our own C++ COM component fired and were received just fine. Using MSINFO32 to compare the loaded modules on a working system to those on a failing system we determined that this was caused by STDOLE.DLL not being in the GAC and hence not loaded into the faulty process. Dragging this file into the GAC caused events to come back fine from the fingerprint COM library. So what does stdole.dll do? It's 16k in size so it can't be much... is it some sort of link to another library like STDOLE32? How come its absence causes such odd behavior? How do we distribute stdole.dll? This is an XCOPY deploy app and we don't use the GAC. Should we package it as a resource and use the System.EnterpriseServices.Internal.Publish.GacInstall to ensure it's in the GAC?

AS3: Array of objects parsed from XML remains with zero length

- by Joel Alejandro

I'm trying to parse an XML file and create an object array from its data. The data is converted to MediaAlbum classes (class of my own). The XML is parsed correctly and the object is loaded, but when I instantiate it, the Albums array is of zero length, even when the data is loaded correctly. I don't really know what the problem could be... any hints? import Nem.Media.*; var mg:MediaGallery = new MediaGallery("test.xml"); trace(mg.Albums.length); MediaGallery class: package Nem.Media { import flash.net.URLRequest; import flash.net.URLLoader; import flash.events.*; public class MediaGallery { private var jsonGalleryData:Object; public var Albums:Array = new Array(); public function MediaGallery(xmlSource:String) { var loader:URLLoader = new URLLoader(); loader.load(new URLRequest(xmlSource)); loader.addEventListener(Event.COMPLETE, loadGalleries); } public function loadGalleries(e:Event):void { var xmlData:XML = new XML(e.target.data); var album; for each (album in xmlData.albums) { Albums.push(new MediaAlbum(album.attribute("name"), album.photos)); } } } } XML test source: <gallery <albums <album name="Fútbol 9" <photos <photo width="600" height="400" filename="foto1.jpg" / <photo width="600" height="400" filename="foto2.jpg" / <photo width="600" height="400" filename="foto3.jpg" / </photos </album <album name="Fútbol 8" <photos <photo width="600" height="400" filename="foto4.jpg" / <photo width="600" height="400" filename="foto5.jpg" / <photo width="600" height="400" filename="foto6.jpg" / </photos </album </albums </gallery

jQuery ajax form submit - multiple post/get requests caused when validation fails

- by kenny99

Hi, I have a problem where if a form submission (set up to submit via AJAX) fails validation, the next time the form is submitted, it doubles the number of post requests - which is definitely not what I want to happen. I'm using the jQuery ValidationEngine plugin to submit forms and bind validation messages to my fields. This is my code below. I think my problem may lie in the fact that I'm retrieving the form action attribute via $('.form_container form').attr('action') - I had to do it this way as using $(this).attr was picking up the very first loaded form's action attr - however, when i was loading new forms into the page it wouldn't pick up the new form's action correctly, until i removed the $(this) selector and referenced it using the class. Can anyone see what I might be doing wrong here? (Note I have 2 similar form handlers which are loaded on domready, that could also be an issue) $('input#eligibility').live("click", function(){ $(".form_container form").validationEngine({ ajaxSubmit: true, ajaxSubmitFile: $('.form_container form').attr('action'), success : function() { var url = $('input.next').attr('rel'); ajaxFormStage(url); }, failure : function() { //unique stuff for this form } }); }); //generic form handler - all form submissions not flagged with the #eligibility id $('input.next:not(#eligibility)').live("click", function(){ $(".form_container form").validationEngine({ ajaxSubmit: true, ajaxSubmitFile: $('.form_container form').attr('action'), success : function() { var url = $('input.next').attr('rel'); ajaxFormStage(url); }, failure : function() { } }); });

iPhone SDK: loading UITableView from SQLite

- by leon

Hi, I think I got a good handle on UITableViews and on getting/inserting data from/to SQLite db. I am straggling with an architectural question. My application saves 3 values int the database, there can be many/many rows. However would I load them in the table? From all the tutorials I have seen, at one point entire database is loaded in the NSMutableArray or similar object via performing SELECT statement. Then when -(UITableViewCell *) tableView: (UITableView *) tableView cellForRowAtIndexPath: (NSIndexPath *) indexPath called, rows required are dolled out from the previous loaded NSMutableArray (or similar stracture). But what i have have thousands for rows? Why would I pre-load them? Should I just query database each time cellForRowAtIndexPath is called? If so, what would I use as an index? Each row in the table will have an AUTOINCREMENT index, but since some rows may be deleted index will not correspond to rows in the table (in the SQL I may have something like this with row with index 3 missing): 1 Data1 Data1 2 Data2 Data2 4. data3 data3 Thanks

Dojo DataGrid, programmatic creation

- by djna

I'm trying to create a DataGrid dynamically. Declarative creation is working fine: A source of data: <span dojoType="dojo.data.ItemFileReadStore" jsId="theStore" url="dataonly001.json"> </span> a simple layout: <script type="text/javascript" > var layout = [ { field: 'custId', name: 'Id', } // more items elided ... ]; </script> The grid: <body class="tundra" id="mainbody"> <div id="grid" dojoType="dojox.grid.DataGrid" store="theStore" structure="layout" autoWidth="true" ></div> </body> And I get the grid displayed nicely. Instead, I want to create the grid dynamically. For the sake of figuring out what's broken I've tried to use exactly the same layout and store, removing just teh grid declaration and adding this script: <script type="text/javascript" djConfig="parseOnLoad: true, debugAtAllCosts: true"> dojo.addOnLoad(function(){ // initialise and lay out home page console.log("Have a store:" + theStore); console.log("Have a structure:" + layout); var grid = new dojox.grid.DataGrid({ id:"grid", store : theStore, clientSort : "true", structure : layout }); grid.startup(); dojo.place(grid.domNode, dojo.body(), "first"); }); </script> The effect that I get is a completely empty rectangle is displayed. Using FireBug I can see that the DataGrid widget is created but that it has no rows or columns. So my guess is that the datastore or layout are not being passed correctly. However, it does appear that at the point of creation the values of theStore and layout are correct. Suggestions please, or indeed a working example of a programmic grid might solve the problem.

Winforms: How to display a "loading" form?

- by Martijn

I have a grid and when a row is double clicked a form is loaded. However a lot of data must be loaded, so I'd like to display a simple form with the text 'loading, please wait..'. And when all loading is finished, the form must disappear. This is what I have right now, but it doesn't work: Code that invokes the form with lots of data: FormWithLotData form = new FormWithLotData(); form.ShowDialog(this); Constructor of FormWithLotData: // Show load form FormIsLoading frm = new FormIsLoading(); _CloseLoadForm closeForm = new _CloseLoadForm(frm.Close); System.Threading.Thread thread = new System.Threading.Thread(frm.Show); thread.Start(); InitializeComponent(); this.Visible = false; LoadAllData(); this.Visible = true; // Close load form Invoke(closeForm); Hope you can help me out. EDIT: I'd like to show an animated gif on the loading form.

create board for game with events support

- by netmajor

How can I create board for simple game, looks like for chess,but user could dynamically change number of column and rows? In cells I could insert symbol of pawn, like small image or just ellipse or rectangle with fill. This board should have possibility add and remove pawn from cells and move pown from one cell to another. My first idea was Grid. I do it in code behind, but it's hurt to implement events or everything in runtime create board :/ int size = 12; Grid board = new Grid(); board.ShowGridLines = true; for (int i = 0; i < size;i++ ) { board.ColumnDefinitions.Add(new ColumnDefinition()); board.RowDefinitions.Add(new RowDefinition()); } //komputer Rectangle ai = new Rectangle(); ai.Height = 20; ai.Width = 20; ai.AllowDrop = true; ai.Fill = Brushes.Orange; Grid.SetRow(ai, 0); Grid.SetColumn(ai,0); //czlowiek Rectangle hum = new Rectangle(); hum.Height = 20; hum.Width = 20; hum.AllowDrop = true; hum.Fill = Brushes.Green; Grid.SetRow(hum,size); Grid.SetColumn(hum,size); board.Children.Add(ai); board.Children.Add(hum); this.Content = board; It's a way to do this dynamically col and row change in XAML ? It's better way to implement that board create and implement events on move pawn from one cell to another ?

Silently catch windows error popups when calling System.load() in java

- by Marcelo Morales

I have a Java Swing application, which needs to load some native libraries in windows. The problem is that the client could have different versions of those libraries. In one recent version, either the names changed or the order on which the libraries must be loaded changed. To keep up, we iterated over all possible library names but some fail to load (due to it's nonexistence or because another must be loaded previously). This idea works on older Windows but on latter ones it shows a error popup. I saw on question 4058303 (Silently catch windows error popups when calling LoadLibrary) that I need to call SetErrorMode but I am not sure how to call SetErrorMode from jna. I tried to follow the idea from question 11038595 but I am not sure how to proceed. public interface CKernel32 extends Kernel32 { CKernel32 INSTANCE = (CKernel32) Native.loadLibrary("kernel32", CKernel32.class); // TODO: HELP: HOW define the SetErrorMode function } How do I define (from the SetErrorMode documentation): UINT WINAPI SetErrorMode( _In_ UINT uMode ); in the line marked as TODO: HELP:? Thanks in advance

RadAjaxManager problem when showing/hiding control on page loading

- by Lukasz Lysik

I have the webform with dropdown list, label and textbox. Like below: <asp:DropDownList ID="ddlTest" runat="server" AutoPostBack="true"> </asp:DropDownList> <asp:Label ID="lblTest" runat="server" Text="Some text"> </asp:Label> <asp:TextBox ID="edtTest" runat="server"> </asp:TextBox> I want to show/hide label and text box depending on the value selected on dropdown list. So I've added RadAjaxManader: <rad:RadAjaxManager ID="RadAjaxManager1" runat="server"> <AjaxSettings> <rad:AjaxSetting AjaxControlID="ddlTest"> <UpdatedControls> <rad:AjaxUpdatedControl ControlID="lblTest" /> <rad:AjaxUpdatedControl ControlID="edtTest" /> </UpdatedControls> </rad:AjaxSetting> </AjaxSettings> </rad:RadAjaxManager> and procedure "SetupVisibility" which takes value from the dropdown list, does some walidations and desides whether to show or hide the label and the text box. When I use the procedure like this: Protected Sub ddlTest_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlTest.SelectedIndexChanged SetupVisibility() End Sub it works good, but now I want to call SetupVisibility when the page is loaded: Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init SetupVisibility() End Sub The problem occurs in such a scenario: SetupVisibility() hides textbox and label while page is loaded. I change value on ddlTest dropdown list. SetupVisibility() wants to show textbox and label, but then I get the error: Microsoft JScript - runtime error: Cannot update control with ID: ctl00_CPH1_lblTest. The control does not exist. Where is the problem?

Add data to Django form class using modelformset_factory

- by dean

I have a problem where I need to display a lot of forms for detail data for a hierarchical data set. I want to display some relational fields as labels for the forms and I'm struggling with a way to do this in a more robust way. Here is the code... class Category(models.Model): name = models.CharField(max_length=160) class Item(models.Model): category = models.ForeignKey('Category') name = models.CharField(max_length=160) weight = models.IntegerField(default=0) class Meta: ordering = ('category','weight','name') class BudgetValue(models.Model): value = models.IntegerField() plan = models.ForeignKey('Plan') item = models.ForeignKey('Item') I use the modelformset_factory to create a formset of budgetvalue forms for a particular plan. What I'd like is item name and category name for each BudgetValue. When I iterate through the forms each one will be labeled properly. class BudgetValueForm(forms.ModelForm): item = forms.ModelChoiceField(queryset=Item.objects.all(),widget=forms.HiddenInput()) plan = forms.ModelChoiceField(queryset=Plan.objects.all(),widget=forms.HiddenInput()) category = "" < assign dynamically on form creation > item = "" < assign dynamically on form creation > class Meta: model = BudgetValue fields = ('item','plan','value') What I started out with is just creating a dictionary of budgetvalue.item.category.name, budgetvalue.item.name, and the form for each budget value. This gets passed to the template and I render it as I intended. I'm assuming that the ordering of the forms in the formset and the querset used to genererate the formset keep the budgetvalues in the same order and the dictionary is created correctly. That is the budgetvalue.item.name is associated with the correct form. This scares me and I'm thinking there has to be a better way. Any help would be greatly appreciated.
