• C# Events between threads executed in their own thread (How to) ?

  - by Guillaume

  Hello, I'd like to have two Threads. Let's call them : Thread A Thread B Thread A fires an event and thread B listen to this event. When the Thread B Event Listener is executed, it's executed with the Thread A's thread ID, so i guess it is executed within the Thread A. What I'd like to do is be able to fire event to Thread B saying something like: "hey, a data is ready for you, you can deal with it now". This event must be executed in its own Thread because it uses things that only him can access (like UI controls). How can I do that ? Thank you for you help.

• how to deal with async calls in Ajax 4.0(using jquery?)

  - by dexter

  in my code i have done something like this. $.get('/Home/Module/Submit', { moduleName: ModName, moduleParameters: moduleParameters }, function(result) { $("#" + target).html(result); }); when i put alert in the function(result) {..} it shows html perfectly(both in alert and at the 'target'-on the .aspx page) BUT when i remove the alert.. on the page the 'html' don't appear or appear randomly (this method is called multiple times) i think that the 'result' comes to function asynchronously thats why it is not bind with the respective 'div' however in the last iteration it gets bind every time. can we make process stop until data gets bind? or is there any functionality (like alert) which can make data bind.. without disturbing UI (unlike alert)?

• link_to_remote and jquery accordion

  - by badnaam

  I have a standard jquery ui accordion and I load content into it using a link_to_remote tag (in the accordion header). All this works fine. The problem is, once the content is loaded, I dont want a ajax call, I just want the accordion to fold, like it should normally do. I tried doing this using the following jquery but clicking the header hence the link still makes a request. #lbs_list is the div inside the accordion. $j('#lnk_show_benefit').bind('click', function(e) { if ($j('#lbs_list').is(':visible')) { e.preventDefault(); return false; } else { return true; } });

• Usage scenario for svn branches

  - by Paul Knopf

  I have a product that I distribute to my clients. Each client needs some UI customization. I want each client to be able to get updated with new version easily. Can I create a project in svn that serves as a "base project", and then create branches for each client? With that said, will I then be able to commit changes in a branch to the branch, with the option of pushing that change to the core? Can I also perform and "update" command in a branch that will only update changes to the core?

• BlackBerry - Multiple Screens or Single Screen with Content Manager?

  - by Max Gontar

  Hi! I've seen projects which use many screens each one for different layout and functionality. I've seen projects with only one screen (like wizard workflow) where content is changed on user interaction (and this seems to be logical to use single screen in wizards). But also I've seen projects (apps like game or messenger or phone settings utility) which use single screen for different functionalities. I can see such advantages of having single screen in app: keep same decoration design and menu or toolbar (which may be also achieved with inheritance) keep single screen in ui stack (which may be achieved by pop/push screen) easy to handle data over application Can you tell other advantages/disadvantages of single screen app? When its better to use this approach? Thank you!

• Calculating similarites between sentences

  - by codecreator

  I have datbase with thousands of rows of error logs and their description.This error log is for an application that running 24/7. I want to create a dashboard/UI to view the current common errors happening for prodcution support. The problem I am having is that even though there are lot of common errors, the error description differs by the transcation ID or user ID or things that are unique for that sigle prcoess. e.g Error trasaction XYz failed for user 233 e.g 2. Error trasaction XYz failed for user 567 I consider these two erros to be same. So I want to a program that will go through the new error logs and classify them into groups. I am trying to use "edit distance" but its very slow.Since I alraedy have old error logs, i am trying to think of solutions using that information too. Any thoughts?

• How can I delete a row in the view only if the AJAX call & db deletion was successful?

  - by user1760663

  I have a table where each row has a button for deletion. Actually I delete the row everytime without checking if the ajax call was successfull. How can I achieve that, so that the row will only be deleted if the ajax call was ok. Here is my clickhandler on each row $("body").on('click', ".ui-icon-trash" ,function(){ var $closestTr = $(this).closest('tr'); // This will give the closest tr // If the class element is the child of tr deleteRowFromDB(oTable, closestTr); $closestTr.remove() ; // Will delete that }); And here my ajax call function deleteRowFromDB(oTable, sendallproperty){ var deleteEntryRoute = #{jsRoute @Application.deleteConfigurationEntry() /} console.log("route is: " + deleteEntryRoute.url) $.ajax({ url: deleteEntryRoute.url({id: sendallproperty}), type: deleteEntryRoute.method, data: 'id=' + sendallproperty });

• In Xcode, the main controller is hopelessly misconfigured. What are the steps I can take to fix all

  - by MikeN

  Somehow the main .xib file for my iphone project got deleted. I created a replacement .xib file, but the properties are not setup correctly for the MainWindow to load this one. I don't understand and am hopelessly confused about any of the properties and which ones may or may not be sent. What are the X properties that all need to be set to have this work correctly? I've checked all of these, but there appear to be others: 1) The app delegate for the project is set to the new ControllerUI class. 2) The MainWindow.xib shows the correct .xib file as being loaded from (it has a link in its UI to the .xib file that should be loaded on project run. There appear to be other settings that have to be changed and I can't find them. Is there a way in XCode to recreate the MainWindow.xib file? Should I just create a new project and move all of the other files into it?

• clrear coockies and cache from site

  - by salvadore

  Every time i updat my website system UI\Jquery. Users complain that things are not working for them and that they have bugs. Users are internet\computer dummies so they dont know how to clear the coockies or the cache of the browser, so i need to connect to each one of their computers and do it by myself. I spend lots off hours doing it and they always complain. Some of the useres use Chrome, some Firefox. Googled and found no solution for this, Is there any client code operation that will command the browser to clrear its cache or even pop up browser window wich will ask user to confirm the clear?

• "Refreshing" an XML feed on iPhone/Mac OSX

  - by Steve

  Hi all, I'm curious for those of you who are building iPhone apps based on REST/SOAP/XML-RPC or simply pulling down a dynamic XML feed, what does it mean exactly to you when a user says 'refresh' the feed? The straight forward way is to populate some collection, say an NSMutableArray, with whatever you bring down from the feed. If a widget on the UI is available to refresh, I typically do something like: [myMutableArray removeAllObjects]; // follow steps to repopulate myMutableArray It seems this is the least efficient algorithm for refreshing an XML feed. For instance many folks who are building Twitter clients, are appending changes to their existing feed, versus bringing down the entire feed in its complete form again. What kind of algorithms are you using to "refresh" your models when speaking to a server-side data source? Thanks all.

• Dispatcher.CheckAccess() isn't working from my console application, is there a better way.

  - by zimmer62

  I wrote an application in WPF / VB and separated the business logic and UI into different projects. The business layer uses a serial port which runs on a different thread, Now that I'm trying to write a command line interface for the same business layer, it seems to fail when .Invoke() is called. (no error, just doesn't work) I'm pretty sure the reason I had to add in checkaccess and .invoke was because I have collections that would be changed during processing the serial port data and wanted the NotifyCollectionChanged to be handled by WPF data binding. (The reason I'm not 100% sure is because it was months ago I wrote that part and it all worked great from the GUI, now adding the console app has made me rethink some of this) I would like my business layer to run these processes on the thread they were created, I need this to work from both my GUI version and the command line version. Am I misusing the Dispatcher in my business layer? Is there a better way to handle an event from the serial port, and then return to the main thread to processes the data?

• JavaScript: filter() for Objects

  - by AgileMeansDoAsLittleAsPossible

  ECMAScript 5 has the filter() prototype for Array types, but not Object types, if I understand correctly. How would I implement a filter() for Objects in JavaScript? Let's say I have this object: var foo = { bar: "Yes" }; And I want to write a filter() that works on Objects: Object.prototype.filter = function(predicate) { var result = {}; for (key in this) { if (this.hasOwnProperty(key) && !predicate(this[key])) { result[key] = this[key]; } } return result; }; This works when I use it in jsfiddle (http://jsfiddle.net/MPUnL/4/), but when I add it to my site that uses jQuery 1.5 and jQuery UI 1.8.9, I get JavaScript errors in FireBug.

(This is the jquery ui)

• [Flex] Modify components that is not included in the current state?

  - by user322896

  In Flex 4, is it possible to modify components that is not include in the current state? For example, I have labelA included in stateA, how do I change the label text in stateB? If I directly change the label text in stateB, I'll get an null reference error message. One workaround is to include labelA in all states, and set it to be invisible in states other than stateA. However, if the number of this kind of component goes too large, the work becomes tedious, and also I don't think it's reasonable to include unnecessary UI components in unrelated states. Is there better solution for this situation? Thanks! Regards

• Calculate average in LINQ C# with string representation of property name

  - by Paul

  I need to calculate a whole bunch of averages on an List of Surveys. The surveys have lots of properties that are int and double valued. I am creating a business object to handle all the calculations (there are like 100) and I'd rather not code 100 different methods for finding the average for a particular property. I'd like to be able to have the UI pass a string (representing the property) and have the the business object return an average for that property. So, like... int AverageHeightInInches = MyObject.GetIntAverage("HeightInInches"); . . . Then have linq code to calculate the result. Thanks!

• If I write a framework that gets information from the Internet, should I make a degelate or use blocks?

  - by Time Machine

  Say I'm writing a publicly available framework for the Vimeo API. This framework needs to get information from the Internet. Because this can take some time, I need to use threadin to prevent the UI from hanging. Foundation uses delegates for this, like NSURLConnectionDelegate. However, Game Kit uses blocks as callback functions. What is the recommended way of doing this? I know blocks aren't supported in standard GCC versions, but they require less, much less code for the one that uses my framework. Delegates, on the other hand, are real methods and when protocols are used, I'm sure the methods are implemented. Thanks.

• ActionScript - One Button Limit (Exclusive Touch) For Mobile Devices?

  - by TheDarkIn1978

  two years ago, when i was developing an application for the iPhone, i used the following built-in system method on all of my buttons: [button setExclusiveTouch:YES]; essentially, if you had many buttons on screen, this method insured that the application wouldn't be permitted do crazy things when several button events firing at the same time. problematic: ButtonA and ButtonB are available. each button has a mouse up event which fire a specific reorganization/layout of the UI. if both button's events are fired at the same time, their events will likely conflict, causing a strange new layout, perhaps a runtime error. solution: application buttons cancel any current pending mouse up events when said button enters mouse down. private function mouseDownEventHandler(evt:MouseEvent):void { //if other buttons are currently in a mouse down state ready to fire //a mouse up event, cancel them all here. } of course it's simple to manually handle this if there are only a few buttons on stage, but managing buttons becomes more and more complicated / bug-prone if there are several / many buttons available. is there a convenience method available in AIR specifically for this functionality?

• Why can't I set a layout for a page in a QStackedWidget in designer?

  - by cppguy

  Steps to reproduce in designer for Qt 4.8.0 I create a new dialog form in Qt Designer I add a QStackedWidget to the dialog I set the layout of the dialog to make the stacked layout size with the dialog I add a few controls to page one in the stacked widget I select the first page in the stacked widget in the right hand tree view of controls The icon next to that page (which is a QWidget) shows the page is missing a layout When I click one of the layout buttons above, it doesn't change the layout of the page QWidget, it changes the layout of the dialog even though I had explicitly selected the page. Is this a bug in designer? Am I missing something? I really don't want to add the layouts programatically as that prevents me from being able to layout the pages in designer in the same .ui file

• How to change a label's text after loading a html into a dialog

  - by Salsa

  I am opening a modal dialog by loading a form into it. After loading the form, I want to change it's title and one of it's fields' label. I can change the label's text, but after the function returns, the label's text turns back to it's original one. Is it possible to make this kind of change and if so, how? The HTML: <form action="testing.php" method="POST" id="example-form"> <fieldset> <label for="link" id="link-label"></label> </fieldset> </form> The javascript: $(".bt-example").button().click(function() { $('#example-dialog').load('form.html').dialog('open'); $('.ui-dialog-titlebar').text("THIS WORKS!"); $('#example-form #link-label').text("CHANGES AT FIRST, BUT GOES BLANK LATER"); $('#example-dialog').removeClass('invisible'); });

• What options I have to show a sentence parts with different color?

  - by Pentium10

  I have a longer sentence 200 characters. I need to show on the screen having parts of them in different color, like highlighting search results, each with different color. The text should auto wrap with screen width, and have no break sections between parts. I meant with this that I can put sections on a new line. They will have to continue the previous section, only wrap when the screen is off. The best would be an EditText, as I need to allow editing also, but I am wondering I am able to change the color of various sentence parts, or just as a whole. What do you think, with what UI elements can I achieve this view?
