• IE 8 remove line break between nodes with JavaScript

  - by Tokimon

  Ok i have a list of HTML nodes which should be inline with no spacing between them. The problem is, that the nodes are written from a CMS and therefore will come with all sorts of linebreaks and spaces. Therefore I'm removing the spaces with JS using the method descibed in this question. The problem is, however, that in IE (not 9) the white spaces isn't part of the childrens list of the parent node, rendering the method useless in IE. However IE 7 (or at least IE 9 emulating IE 7) ignores the linebreaks, so that one is in the clear. That leaves IE 8 as the troublemaker. I discovered that the line break is actually a part of the outerHTML and that a simple reset of the outerHTML did the trick - like so: node.outerHTML = node.outerHTML However this will reset the node intirely and therefore removing all events and other settings on the node, which isn't really any good. So my question is now: Is there a way to remove that linebreak from the nodes outerHTML whitout resetting the node? I've tried with zoom: 1, but to no avail. Hope anyone has any experience with this.

• JavaFX MouseEvent continues when I remove the object it happened on

  - by Kyle

  It took me a while to realize what was going on with mouse events going through my blocking dialog boxes when I closed them, but I finally figured out why. I still don't know any good way to fix it. I have a custom dialog box (that blocks the mouse) with a close button. When I click the close button, I remove the dialog box from the scene, but JavaFx is still processing the MouseEvent and now it finds that there is nothing blocking the screen behind where the cancel button was, so that component receives a MouseEvent. How do I make the mouseEvent stop processing when I see that they pressed cancel and remove the dialog box? Or, is there a way to make the removing of the dialog box not happen until after it is done processing the MouseEvent? Example Code for the problem: import javafx.stage.Stage; import javafx.scene.Scene; import javafx.scene.shape.Rectangle; import javafx.scene.input.MouseEvent; import javafx.scene.control.Button; var theScene:Scene; var btn:Button; Stage { title: "Application title" scene: theScene= Scene { width: 500 height: 200 content: [ Rectangle{ width: bind theScene.width height: bind theScene.height onMouseClicked: function(e:MouseEvent):Void{ println("Rectangle");} }, Button{ layoutX: 20 layoutY: 50 blocksMouse: true text: "JustPrint" action:function():Void{ println("JustPrint");} }, btn = Button{ layoutX: 20 layoutY: 20 blocksMouse: true text: "Cancel" action:function():Void{ println("Cancel"); delete btn from theScene.content;} }, ] } } When you press "JustPrint" you get: JustPrint When you press "Cancel" you get: Cancel Rectangle

• java.lang.IllegalArgumentException: View not attached to window manager

  - by alex2k8

  I have an activity that starts AsyncTask and shows progress dialog for the duration of operation. The activity is declared NOT be recreated by rotation or keyboard slide. <activity android:name=".MyActivity" android:label="@string/app_name" android:configChanges="keyboardHidden|orientation" > <intent-filter> </intent-filter> </activity> Once task completed, I dissmiss dialog, but on some phones (framework: 1.5, 1.6) such error is thrown: java.lang.IllegalArgumentException: View not attached to window manager at android.view.WindowManagerImpl.findViewLocked(WindowManagerImpl.java:356) at android.view.WindowManagerImpl.removeView(WindowManagerImpl.java:201) at android.view.Window$LocalWindowManager.removeView(Window.java:400) at android.app.Dialog.dismissDialog(Dialog.java:268) at android.app.Dialog.access$000(Dialog.java:69) at android.app.Dialog$1.run(Dialog.java:103) at android.app.Dialog.dismiss(Dialog.java:252) at xxx.onPostExecute(xxx$1.java:xxx) My code is: final Dialog dialog = new AlertDialog.Builder(context) .setTitle("Processing...") .setCancelable(true) .create(); final AsyncTask<MyParams, Object, MyResult> task = new AsyncTask<MyParams, Object, MyResult>() { @Override protected MyResult doInBackground(MyParams... params) { // Long operation goes here } @Override protected void onPostExecute(MyResult result) { dialog.dismiss(); onCompletion(result); } }; task.execute(...); dialog.setOnCancelListener(new OnCancelListener() { @Override public void onCancel(DialogInterface arg0) { task.cancel(false); } }); dialog.show(); From what I have read (http://bend-ing.blogspot.com/2008/11/properly-handle-progress-dialog-in.html) and seen in Android sources, it looks like the only possible situation to get that exception is when activity was destroyed. But as I have mentioned, I forbid activity recreation for basic events. So any suggestions are very appreciated.

• JPanel not listening to key event when there is a child component with JButton on it

  - by Yifu

  I'm working on a map editor for my college project. And I had a problem that the map panel is not listening key event while it should. This happens when I add a ToolBarPane (which extends JPanel) with JComponent such as JButton, JComboBox that implements ActionListener on it AND the map panel (which extends the JPanel) together on to the Frame (I used BorderLayout). I have System.out.println statement to test if the key press is received, and it's not printing, if I remove the ToolBar, the key listener works again, so is the mouseListenner is disabled just like the keyListener, which means I can't handle press events etc, but the mouseListener works fine and I can still handle mouse move event. Here is a screen shot how it works without the ToolBarPane http://img684.imageshack.us/img684/3232/sampleku.png note that you can use the mouse to put images on the map, you can also select images using the mouse just like a laser tool, and by pressing number key you can switch between different images, this works fine until I add the ToolBarPane which shows like this: img291.imageshack.us/img291/8020/failve.png (please add http before that, i can only post one hyperlink) (I can't post images here cuz im a new user) With the ToolBarPane on I was no longer able to handle the key event. I guess it might by that the focus as been transfered to that panel somehow, but not sure at all. Does and body know this and can help me out? Thanks very much

• Is there a reason why SSIS significantly slows down after a few minutes?

  - by Mark

  I'm running a fairly substantial SSIS package against SQL 2008 - and I'm getting the same results both in my dev environment (Win7-x64 + SQL-x64-Developer) and the production environment (Server 2008 x64 + SQL Std x64). The symptom is that initial data loading screams at between 50K - 500K records per second, but after a few minutes the speed drops off dramatically and eventually crawls embarrasingly slowly. The database is in Simple recovery model, the target tables are empty, and all of the prerequisites for minimally logged bulk inserts are being met. The data flow is a simple load from a RAW input file to a schema-matched table (i.e. no complex transforms of data, no sorting, no lookups, no SCDs, etc.) The problem has the following qualities and resiliences: Problem persists no matter what the target table is. RAM usage is lowish (45%) - there's plenty of spare RAM available for SSIS buffers or SQL Server to use. Perfmon shows buffers are not spooling, disk response times are normal, disk availability is high. CPU usage is low (hovers around 25% shared between sqlserver.exe and DtsDebugHost.exe) Disk activity primarily on TempDB.mdf, but I/O is very low (< 600 Kb/s) OLE DB destination and SQL Server Destination both exhibit this problem. To sum it up, I expect either disk, CPU or RAM to be exhausted before the package slows down, but instead its as if the SSIS package is taking an afternoon nap. SQL server remains responsive to other queries, and I can't find any performance counters or logged events that betray the cause of the problem. I'll gratefully reward any reasonable answers / suggestions.

• Can I delay the keyup event for jquery?

  - by Paul

  I'm using the rottentomatoes movie API in conjunction with twitter's typeahead plugin using bootstrap 2.0. I've been able to integerate the API but the issue I'm having is that after every keyup event the API gets called. This is all fine and dandy but I would rather make the call after a small pause allowing the user to type in several characters first. Here is my current code that calls the API after a keyup event: var autocomplete = $('#searchinput').typeahead() .on('keyup', function(ev){ ev.stopPropagation(); ev.preventDefault(); //filter out up/down, tab, enter, and escape keys if( $.inArray(ev.keyCode,[40,38,9,13,27]) === -1 ){ var self = $(this); //set typeahead source to empty self.data('typeahead').source = []; //active used so we aren't triggering duplicate keyup events if( !self.data('active') && self.val().length > 0){ self.data('active', true); //Do data request. Insert your own API logic here. $.getJSON("http://api.rottentomatoes.com/api/public/v1.0/movies.json?callback=?&apikey=MY_API_KEY&page_limit=5",{ q: encodeURI($(this).val()) }, function(data) { //set this to true when your callback executes self.data('active',true); //Filter out your own parameters. Populate them into an array, since this is what typeahead's source requires var arr = [], i=0; var movies = data.movies; $.each(movies, function(index, movie) { arr[i] = movie.title i++; }); //set your results into the typehead's source self.data('typeahead').source = arr; //trigger keyup on the typeahead to make it search self.trigger('keyup'); //All done, set to false to prepare for the next remote query. self.data('active', false); }); } } }); Is it possible to set a small delay and avoid calling the API after every keyup?

• What is the best free cross-platform OpenGL GUI library for a video game?

  - by Jim Buck

  It must come with source. I've looked at these which look semi-promising: glgooey, guichan, and cegui. I've come across others that look more Windows-y than game-y, but that's not the direction I am looking to go in. I would like some simple functionality of typical controls (lists, dropdown box, etc.) but with support for graphical widgets that you would normally find in game frontends. Mouse clicking, dragging, dropping, etc. and sound effect hooks would be nice. (These libs often leave hooks for the external system to tell it when/where mouse events are occurring.) It would get rendered on top of what my own 3D engine is rendering for the game, so it must be able to play nicely with rendering code outside of the lib. The best criteria is whether or not a reasonable 2D game could be implemented just with the GUI library and minimal glue code. (By glue code, I mean init code, hooking up the mouse, and game logic.) I am creating a 3D game, but this criteria gives a pretty solid idea of what level of interactivity I would like in the GUI.

• Dynamic editor upload into web page. Need advice

  - by Andrew Florko

  Hello everybody, I am writing intranet site for tracking employees science activities in organization. There lots of editable information on each personal page (science degree, publications & so on) so I upload editor per request (user clicks "edit" and modal dialog with html editor: set of textboxes/comboboxes/autocomplete features & validation logic appears). Editor is html layout that is wrapped with jquery dialog plugin + some logic, written as javascript functions that should be invoked from the callee page (onsubmit, validate, afterLoad editor events). There are also attributes (editor preferrable with and height) that are passed to callee page also. Currently I send these functions & attribute as ... function onsubmit() { }; function validate() { } var width = 640; var height = 800 ... code that is embedded into the request page. Function calls and editor markup wrap with jquery plugin completed in the callee page. It works, but I have some try { call editor event handler } catch { } stuff in callee page (because not every editor provides these functions) and some attributes (editor width & height for instance) that are loaded as variables declared in javascript. Please, suggest, is there a better approach to build & use custom editors for my situation. Thank you in advance!

• How does Backbone.js connect View to Model

  - by William Sham

  I am trying to learn backbone.js through the following example. Then I got stuck at the point ItemView = Backbone.View.extend why you can use this.model.get? I thought this is referring to the instance of ItemView that would be created. Then why would ItemView has a model property at all?!! (function($){ var Item = Backbone.Model.extend({ defaults: { part1: 'hello', part2: 'world' } }); var List = Backbone.Collection.extend({ model: Item }); var ItemView = Backbone.View.extend({ tagName: 'li', initialize: function(){ _.bindAll(this, 'render'); }, render: function(){ $(this.el).html('<span>'+this.model.get('part1')+' '+this.model.get('part2')+'</span>'); return this; } }); var ListView = Backbone.View.extend({ el: $('body'), events: { 'click button#add': 'addItem' }, initialize: function(){ _.bindAll(this, 'render', 'addItem', 'appendItem'); this.collection = new List(); this.collection.bind('add', this.appendItem); this.counter = 0; this.render(); }, render: function(){ $(this.el).append("<button id='add'>Add list item</button>"); $(this.el).append("<ul></ul>"); _(this.collection.models).each(function(item){ appendItem(item); }, this); }, addItem: function(){ this.counter++; var item = new Item(); item.set({ part2: item.get('part2') + this.counter }); this.collection.add(item); }, appendItem: function(item){ var itemView = new ItemView({ model: item }); $('ul', this.el).append(itemView.render().el); } }); var listView = new ListView(); })(jQuery);

• stop android emulator call

  - by Shahzad Younis

  I am working on an Android application, having functionality like voicemail. I am using BroadcastReceiver to get dialing events. I have to get the event "WHEN CALL IS UNANSWERED (not picked after few rings) FROM RECEIVER". I will do some actions on caller end against this event. I am using AVD emulator, and I do call from one instance to another instance and it calls perfectly, but the problem is: It continuously calls until I reject or accept the call. This way I cannot detect that "CALL IS UNANSWERED AFTER A NUMBER OF RINGS". So I want the Caller emulator to drop the call after a number of rings (if unanswered) like a normal phone. I can do it (drop the call after some time) by writing some code, but I need the natural functionality of phone in the emulator. Can anyone please guide me? Is there any settings in the emulator? Or something else? The code is shown below in case it helps: public class MyPhoneReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Bundle extras = intent.getExtras(); if (extras != null) { String state = "my call state = " + extras.getString(TelephonyManager.EXTRA_STATE); Log.w("DEBUG", state); } }

• What Getters and Setters should and shouldn't do.

  - by cyclotis04

  I've run into a lot of differing opinions on Getters and Setters lately, so I figured I should make it into it's own question. A previous question of mine received an immediate comment (later deleted) that stated setters shouldn't have any side effects, and a SetProperty method would be a better choice. Indeed, this seems to be Microsoft's opinion as well. However, their properties often raise events, such as Resized when a form's Width or Height property is set. OwenP also states "you shouldn't let a property throw exceptions, properties shouldn't have side effects, order shouldn't matter, and properties should return relatively quickly." Yet Michael Stum states that exceptions should be thrown while validating data within a setter. If your setter doesn't throw an exception, how could you effectively validate data, as so many of the answers to this question suggest? What about when you need to raise an event, like nearly all of Microsoft's Control's do? Aren't you then at the mercy of whomever subscribed to your event? If their handler performs a massive amount of information, or throws an error itself, what happens to your setter? Finally, what about lazy loading within the getter? This too could violate the previous guidelines. What is acceptable to place in a getter or setter, and what should be kept in only accessor methods?

• iPhone toolbar shared by multiple views

  - by codemonkey

  Another iPhone noob question. The app I'm building needs to show a shared custom UIToolbar for multiple views (and their subviews) within a UITabBarController framework. The contents of the custom toolbar are the same across all the views. I'd like to be able to design the custom toolbar as a xib and handle UI events from its own controller class (I'm assuming I can subclass UIToolbar to do so?). That way I could define IBOutlet & IBAction items, etc. Then I could associate this custom toolbar with eachs of the UITabBarController views (and their subviews). But I'm having trouble finding out whether that's possible - and if so, how to do it. In particular, I want to be able to push new views onto UINavigationControllers that are each associated with parent UITabBarController tabs. So, to summarize, I want a: custom toolbar shared by multiple views which are managed by multiple navigation controllers and the navigation controllers are associated with different tabs of a parent tab bar controller The tab bar controller itself is launched modally, though I don't believe that's relevant. Anyway, the tab bar controller is working, as are its child navigation controllers. I'm just having a little trouble figuring out how to persist the shared toolbar to the various subviews. I'd settle for a good clean way of implementing programmatically... though I'd prefer the flexibility of keeping the toolbar's visual design in a xib. Anyone have any suggestions?

• App is fast on 3GS but slow on 3G

  - by Anthony Chan

  Hi all, I'm new to computer coding and have just finished coding an app and tested it on both 3G and 3GS. On 3GS, it worked as normal as on the simulator. However, when I tried to run it on 3G, the app becomes extremely slow. I'm not sure what's the reason and I hope someone could shed some light on me. Generally, my app has a couple of view controller classes, with one of them being the title page, one being the main page, one is setting, etc. I used a dissolve to transition from the title page to the main page. But even this simple transition shows un-smooth performance on a 3G! My other part of the app involves zooming in to some images by scaling up the images, switching images by push or dissolve upon receiving touch events, saving photos into photo library and storing and retrieving some photos in a folder and some data in a SQlite database, each showing un-smooth actions. Compared with some heavy graphic or heavy maths app, I think mine is pretty simple. I totally have no clue why the app would behave so slow and un-smooth that it is barely useful on a 3G. Any help/ direction would be much appreciated. Thanks for helping out.

• Low Level Console Input

  - by Soulseekah

  I'm trying to send commands to to the input of a cmd.exe application using the low level read/write console functions. I have no trouble reading the text (scraping) using the ReadConsole...() and WriteConsole() functions after having attached to the process console, but I've not figured out how to write for example "dir" and have the console interpret it as a sent command. Here's a bit of my code: CreateProcess(NULL, "cmd.exe", NULL, NULL, FALSE, CREATE_NEW_CONSOLE, NULL, NULL, &si, &pi); AttachConsole(pi.dwProcessId); strcpy(buffer, "dir"); WriteConsole(GetStdHandle(STD_INPUT_HANDLE), buffer, strlen(buffer), &charRead, NULL); STARTUPINFO attributes of the process are all set to zero, except, of course, the .cb attribute. Nothing changes on the screen, however I'm getting an Error 6: Invalid Handle returned from WriteConsole to STD_INPUT_HANDLE. If I write to (STD_OUTPUT_HANDLE) I do get my dir written on the screen, but nothing of course happens. I'm guessing SetConsoleMode() might be of help, but I've tried many mode combinations, nothing helped. I've also created a quick console application that waits for input (scanf()) and echoes back whatever goes in, didn't work. I've also tried typing into the scanf() promp and then peek into the input buffer using PeekConsoleInput(), returns 0, but the INPUT_RECORD array is empty. I'm aware that there is another way around this using WriteConsoleInput() to directly inject INPUT_RECORD structured events into the console, but this would be way too long, I'll have to send each keypress into it. I hope the question is clear. Please let me know if you need any further information. Thanks for your help.

• GWT: creating a text widget for highly customized data entry

  - by Caffeine Coma

  I'm trying to implement a kind of "guided typing" widget for data entry, in which the user's text entry is highly controlled and filtered. When the user types a particular character I need to intercept and filter it before displaying it in the widget. Imagine if you will, a Unix shell embedded as a webapp; that's the kind of thing I'm trying to implement. I've tried two approaches. In the first, I extend a TextArea, and add a KeyPressHandler to filter the characters. This works, but the browser-provided spelling correction is totally inappropriate, and I don't see how to turn it off. I've tried: DOM.setElementProperty(textArea.getElement(), "spellcheck", "false"); But that seems to have no effect- I still get the red underlines over "typos". In the second approach I use a FocusWidget to get KeyPress events, and a separate Label or HTML widget to present the filtered characters back to the user. This avoids the spelling correction issue, but since the FocusWidget is not a TextArea, the browser tends to intercept certain typed characters for internal use; e.g. FireFox will use the "/" character to begin a "Quick Find" on the page, and hitting Backspace will load the previous web page. Is there a better way to accomplish what I'm trying to do?

• Custom UITableView headerView disappears after memory warning

  - by psychotik

  I have a UITableViewController. I create a custom headerView for it's tableView in the loadView method like so: (void)loadView { [super loadView]; UIView* containerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, width, height * 2 )]; containerView.tag = 'cont'; containerView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin; UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(padding, height, width, height); ... //configure UIButton and events UIImageView* imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"] highlightedImage:[UIImage imageNamed:@"highlight.png"]]; imageView.frame = CGRectMake(0, 0, width, height ); ... //configure UIImageView [containerView addSubview:button]; [containerView addSubview:imageView]; self.tableView.tableHeaderView = containerView; [imageView release]; [containerView release]; } None of the other methods (viewDidLoad/Unload, etc) are overloaded. This controller is hosted in a tab. When I switch to another tab and simulate a memory warning, and then come back to this tab, my UITableView is missing my custon header. All the rows/section are visible as I would expect. Putting a BP in the loadView code above, I see it being invoked when I switch back to the tab after the memory warning, and yet I can't actually see the header. Any ideas about what I'm missing here? EDIT: This happens on the device and the simulator. On the device, I just let a memory warning occur by opening a bunch of different apps while mine is in the background.

• Syncing two AS3 NetStreams

  - by Lowgain

  I'm writing an app that requires an audio stream to be recording while a backing track is played. I have this working, but there is an inconsistent gap in between playback and record starting. I don't know if I can do anything to make the sync perfect every time, so I've been trying to track what time each stream starts so I can calculate the delay and trim it server-side. This also has proved to be a challenge as no events seem to be sent when a connection starts (as far as I know). I've tried using various properties like the streams' buffer sizes, etc. I'm thinking now that as my recorded audio is only mono, I may be able to put some kind of 'control signal' on the second stereo track which I could use to determine exactly when a sound starts recording (or stick the whole backing track in that channel so I can sync them that way). This leaves me with the new problem of properly injecting this sound into the NetStream. If anyone has any idea whether or not any of these ideas will work, how to execute them, or some alternatives, that would be extremely helpful! Been working on this issue for awhile

• What are major differences between C# and Java?

  - by enba

  I just want to clarify one thing. This is not a question on which one is better, that part I leave to someone else to discuss. I don't care about it. I've been asked this question on my job interview and I thought it might be useful to learn a bit more. These are the ones I could come up with: Java is "platform independent". Well nowadays you could say there is the Mono project so C# could be considered too but I believe it is a bit exaggerating. Why? Well, when a new release of Java is done it is simultaneously available on all platforms it supports, on the other hand how many features of C# 3.0 are still missing in the Mono implementation? Or is it really CLR vs. JRE that we should compare here? Java doesn't support events and delegates. As far as I know. In Java all methods are virtual Development tools: I believe there isn't such a tool yet as Visual Studio. Especially if you've worked with team editions you'll know what I mean. Please add others you think are relevant. Update: Just popped up my mind, Java doesn't have something like custom attributes on classes, methods etc. Or does it?

• Reporting Services "cannot connect to the report server database"

  We have Reporting Services running, and twice in the past 6 months it has been down for 1-3 days, and suddenly it will start working again.

• Field Members vs Method Variables?

  - by Braveyard

  Recently I've been thinking about performance difference between class field members and method variables. What exactly I mean is in the example below : Lets say we have a DataContext object for Linq2SQL class DataLayer { ProductDataContext context = new ProductDataContext(); public IQueryable<Product> GetData() { return context.Where(t=>t.ProductId == 2); } } In the example above, context will be stored in heap and the GetData method variables will be removed from Stack after Method is executed. So lets examine the following example to make a distinction : class DataLayer { public IQueryable<Product> GetData() { ProductDataContext context = new ProductDataContext(); return context.Where(t=>t.ProductId == 2); } } (*1) So okay first thing we know is if we define ProductDataContext instance as a field, we can reach it everywhere in the class which means we don't have to create same object instance all the time. But lets say we are talking about Asp.NET and once the users press submit button the post data is sent to the server and the events are executed and the posted data stored in a database via the method above so it is probable that the same user can send different data after one another.If I know correctly after the page is executed, the finalizers come into play and clear things from memory (from heap) and that means we lose our instance variables from memory as well and after another post, DataContext should be created once again for the new page cycle. So it seems the only benefit of declaring it publicly to the whole class is the just number one text above. Or is there something other? Thanks in advance... (If I told something incorrect please fix me.. )

• Problem with mouse event on a user control (wpf).

  - by csciguy

  All, I have a user control, defined as follows. <UserControl x:Class="IDOView.AnimatedCharacter" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:local="clr-namespace:IDOView" mc:Ignorable="d" Background="Transparent" > <Image Name="displayImage" Height="Auto" Width="Auto" Stretch="Fill" IsHitTestVisible="True"/> The control is added to a main page twice, as follows. <local:customControl x:Name="A1" Height="259" Width="197" DisplayImage="circle.png" Canvas.Left="-279" Canvas.Top="-56" MouseLeftButtonUp="DoA1"> <local:customControl x:Name="A1" Height="259" Width="197" DisplayImage="square.png" Canvas.Left="-209" Canvas.Top="-56" MouseLeftButtonUp="DoA2"> Essentially, about half of the circle is behind the square. I need the square image in this case to pass through events to the circle behind it. The square has an element cut out of it (transparent). What is happening now is that the circle event only registers if I click on the region that is not covered by the square. Surely there has to be a way to bubble this event, or click-through?

• jQuery: bind generated elements

  - by superUntitled

  Hello, thank you for taking time to look at this. I am trying to code my very first jQuery plugin and have run into my first problem. The plugin is called like this <div id="kneel"></div> <script type="text/javascript"> $("#kneel").zod(1, { }); </script> It takes the first option (integer), and returns html content that is dynamically generated by php. The content that is generated needs to be bound by a variety of functions (such as disabling form buttons and click events that return ajax data. The plugin looks like this (I have included the whole plugin in case that matters)... (function( $ ){ $.fn.zod = function(id, options ) { var settings = { 'next_button_text': 'Next', 'submit_button_text': 'Submit' }; return this.each(function() { if ( options ) { $.extend( settings, options ); } // variables var obj = $(this); /* these functions contain html elements that are generated by the get() function below */ // disable some buttons $('div.bario').children('.button').attr('disabled', true); // once an option is selected, enable the button $('input[type="radio"]').live('click', function(e) { $('div.bario').children('.button').attr('disabled', false); }) // when a button is clicked, return some data $('.button').bind('click', function(e) { e.preventDefault(); $.getJSON('/returnSomeData.php, function(data) { $('.text').html('<p>Hello: ' + data + '</p>'); }); // generate content, this is the content that needs binding... $.get('http://example.com/script.php?id='+id, function(data) { $(obj).html(data); }); }); }; })( jQuery ); The problem I am having is that the functions created to run on generated content are not binding to the generated content. How do I bind the content created by the get() function?

• Async WebRequest Timeout Windows Phone 7

  - by Tyler

  Hi All, I'm wondering what the "right" way of timing out an HttpWebRequest is on Windows Phone7? I've been reading about ThreadPool.RegisterWaitForSingleObject() but this can't be used as WaitHandles throw a Not implemented exception at run time. I've also been looking at ManualReset events but A) Don't understand them properly and B) Don't understand how blocking the calling thread is an acceptable way to implement a time out on an Async request. Here's my existing code sans timeout, can someone please show me how I would add a timeout to this? public static void Get(Uri requestUri, HttpResponseReceived httpResponseReceivedCallback, ICredentials credentials, object userState, bool getResponseAsString = true, bool getResponseAsBytes = false) { var httpWebRequest = (HttpWebRequest)WebRequest.Create(requestUri); httpWebRequest.Method = "GET"; httpWebRequest.Credentials = credentials; var httpClientRequestState = new JsonHttpClientRequestState(null, userState, httpResponseReceivedCallback, httpWebRequest, getResponseAsString, getResponseAsBytes); httpWebRequest.BeginGetResponse(ResponseReceived, httpClientRequestState); } private static void ResponseReceived(IAsyncResult asyncResult) { var httpClientRequestState = asyncResult.AsyncState as JsonHttpClientRequestState; Debug.Assert(httpClientRequestState != null, "httpClientRequestState cannot be null. Fatal error."); try { var webResponse = (HttpWebResponse)httpClientRequestState.HttpWebRequest.EndGetResponse(asyncResult); } }

• What's the correct place to share application logic in CakePHP?

  - by Pichan

  I guess simple answer to the question would be a component. Although I agree, I feel weird having to write a component for something so specific. For example, let's say I have a table of users. When a user is created, it should form a chain reaction of events, initiating different kinds of data related to the user all around the database. I figured it would be best to avoid directly manipulating the database from different controllers and instead pack all that neatly in a method. However since some logic needs to be accesed separately, I really can't have the whole package in a single method. Instead I thought it would be logical to break it up to smaller pieces(like $userModelOrController->createNew() and $candyStorageModelOrController->createNew()) that only interact with their respective database table. Now, if the logic is put to the model, it works great until I need to use other models. Of course it's possible, but when compared to loading models in a controller, it's not that simple. It's like a Cake developer telling me "Sure, it's possible if you want to do it that way but that's not how I would do it". Then, if the logic is put to the controller, I can access other models really easy through $this->loadModel(), but that brings me back to the previously explained situation since I need to be able to continue the chain reaction indefinitely. Accessing other controllers from a controller is possible, but again there doesn't seem to be any direct way of doing so, so I'm guessing I'm still not doing it right. By using a component this problem could be solved easily, since components are available to every controller I want. But like I wrote at the beginning, it feels awkward to create a component specifically for this one task. To me, components seem more like packages of extra functionality(like the core components) and not something to share controller-specific logic. Since I'm new to this whole MVC thing, I could've completely misunderstood the concept. Once again, I would be thankful if someone pointed me to the right direction :)

• PhotoChooserTask + Navigation.

  - by user562405

  I taken two Images & added event (MouseButtonDown) for them. When first image handles event to open Gallery. Second image handles events for open camera. When user has choosed his image from the gallery, I want to navigate to next page. Its navigates. But before completing navigation process, it displays MainPage & then moves toward next page. I didnt want to display the MainPage once user chooses the image from the gallery. Plz help. Thanks in advance. public partial class MainPage : PhoneApplicationPage { PhotoChooserTask objPhotoChooser; CameraCaptureTask cameraCaptureTask; // Constructor public MainPage() { InitializeComponent(); objPhotoChooser = new PhotoChooserTask(); objPhotoChooser.Completed += new EventHandler<PhotoResult>(objPhotoChooser_Completed); cameraCaptureTask = new CameraCaptureTask(); cameraCaptureTask.Completed += new EventHandler<PhotoResult>(objCameraCapture_Completed); } void objPhotoChooser_Completed(object sender, PhotoResult e) { if (e != null && e.TaskResult == TaskResult.OK) { //Take JPEG stream and decode into a WriteableBitmap object App.CapturedImage = PictureDecoder.DecodeJpeg(e.ChosenPhoto); //Delay navigation until the first navigated event NavigationService.Navigated += new NavigatedEventHandler(navigateCompleted); } } void navigateCompleted(object sender, EventArgs e) { //Do the delayed navigation from the main page this.NavigationService.Navigate(new Uri("/ImageViewer.xaml", UriKind.RelativeOrAbsolute)); NavigationService.Navigated -= new NavigatedEventHandler(navigateCompleted); } void objCameraCapture_Completed(object sender, PhotoResult e) { if (e.TaskResult == TaskResult.OK) { //Take JPEG stream and decode into a WriteableBitmap object App.CapturedImage = PictureDecoder.DecodeJpeg(e.ChosenPhoto); //Delay navigation until the first navigated event NavigationService.Navigated += new NavigatedEventHandler(navigateCompleted); } } protected override void OnBackKeyPress(System.ComponentModel.CancelEventArgs e) { e.Cancel = true; } private void image1_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { objPhotoChooser.Show(); } private void image2_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { cameraCaptureTask.Show(); }
