  • ngModel and component with isolated scope

    - by Artem Andreev
    I am creating simple ui-datetime directive. It splits javascript Date object into _date, _hours and _minutes parts. _date uses jquery ui datepicker, _hours and _minutes - number inputs. See example: http://jsfiddle.net/andreev_artem/nWsZp/3/ On github: https://github.com/andreev-artem/angular_experiments/tree/master/ui-datetime As far as I understand - best practice when you create a new component is to use isolated scope. When I tried to use isolated scope - nothing works. ngModel.$viewValue === undefined. When I tried to use new scope (my example, not so good variant imho) - ngModel uses value on newly created scope. Of course I can create directive with isolated scope and work with ngModel value through "=expression" (example). But I think that working with ngModelController is a better practice. My questions: Can I use ngModelController with isolated scope? If it is not possible which solution is better for creating such component?

  • Facebook: "URL could not be liked because it has been blocked" error in iOS app

    - by Andrew Madsen
    I'm working on an iOS app that allows the user to like a Facebook page within the app. I've implemented this using FacebookLikeView. During the course of testing this functionality, I've liked and unliked the same page multiple times. Unfortunately, this seems to have triggered Facebook's spam detection. Now, when trying to like a page using the like button displayed by FacebookLikeView, the following error is presented: "URL could not be liked because it has been blocked". Based on reports of the same problem found by searching the web, I've filled out this form to request that Facebook remove the block. However, I've received no response from them. I'm not sure how to proceed. Has anyone else run into this issue and successfully solved it?

  • SQL multiple primary keys - localization

    - by Max Malmgren
    I am trying to implement some localization in my database. It looks something like this (prefixes only for clarification) tbl-Categories ID Language Name tbl-Articles ID CategoryID Now, in my tbl-Categories, I want to have primary keys spanning ID and language, so that every combination of ID and language is unique. In tbl-Articles I would like a foreign key to reference ID in categories, but not Language, since I do not want to bind an article to a certain language, only category. Of course, I cannot add a foreign key to part of the primary key. I also cannot have the primary key only on the ID of categories, since then there can only be one language. Having no primary keys disables foreign keys altogether, and that is also not a great solution. Do you have any ideas how I can solve this in an elegant fashion? Thanks.

  • Can I see shader preprocessor output?

    - by GLaddict
    I am using #defines, which I pass runtime to my shader sources based on program state, to optimize my huge shaders to be less complex. I would like to write the optimized shader to a file so that next time I run my program, I do not have to pass the #defines again, but I can straight compile the optimized shaders during program startup because now I know what kind of shaders by program needs. Is there a way to get the result from shader preprocessor? I can of course store the #define values to a file and based on that compile the shaders during program startup but that would not be as elegant.

  • C++ this as thread parameter, variables unavailable

    - by brecht
    I have three classes: class Rtss_Generator { int mv_transfersize; } class Rtss_GenSine : Rtss_Generator class Rtss_GenSineRpm : Rtss_GenSine Rtss_GenSine creates a thread in his constructer, it is started immediatly and the threadfunction is off-course declared static, waiting for an event to start calculating. the problem: all the variables that are accessed through the gen-pointer are 0, but it does not fail. Also, this-address in the constructer and the gen-pointer-address in the thread are the same, so the pointer is ok. this code is created and compile in visual studio 6.0 service pack 2003 ORIGINAL CODE no thread Rtss_GenSine::getNextData() { //[CALCULATION] //mv_transferSize is accessible and has ALWAYS value 1600 which is ok } NEW CODE Rtss_GenSine::Rtss_GenSine() { createThread(NULL, threadFunction, (LPVOID) this,0,0); } Rtss_GenSine::getNextData() { SetEvent(startCalculating); WaitForSingleObject(stoppedCalculaing, INFINITE); } DWORD Rtss_GenSine::threadFunction(LPVOID pParam) { Rtss_GenSine* gen = (Rtss_GenSine*) pParam; while(runThread) { WaitForSingleObject(startCalculating, INFINITE); ResetEvent(startCalculating) //[CALCULATION] //gen->mv_transferSize ---> it does not fail, but is always zero //all variables accessed via the gen-pointer are 0 setEvent(stoppedCalculaing) } }

  • Increased kerning on website text

    - by Bradley Herman
    We're developing a site for a client right now and my boss (designer only) is once again making me increase letter-spacing on the text so that it looks 'prettier'. I am of the firm belief that this often causes eye-strain and hinders readability in body copy, but being the boss, she is of course always 'right' until I can provide her with examples showing why she's wrong (generally pretty easy). In this case, however, I can't find any articles talking about eye-strain and kerning, so I figured I'd ask what you guys think about the issue of increased letter-spacing in web text. Take a look at http://sparktoignite.com/allograft/process.php and tell me how you feel about the body copy. We're using font-embedding, so you'll only see the proper font in FF, Safari, and Chrome. Let me know what you guys think about the readability and eye-strain caused by the font. My boss currently thinks it's 100% perfect (she wanted the kerning increased further, but I talked her down luckily).

  • Multi-platform development from one computer

    - by iama
    I am planning to build a new development computer for both Windows & Linux platforms. On Windows, my development would be primarily in .NET/C#/IIS/MSSQL Server. On Linux—preferably Ubuntu—my development would be in Ruby and Python. I am thinking of buying a laptop with Windows 7 pre-installed with 4GB RAM, Intel Core 2 Duo, and 320 GB HD; running 2 VMs for both Windows and Linux development with the host OS as my work station. Of course, I would be running DBs and web servers on the respective platforms. Is this a typical setup? My only concern is running two VMs side by side. Not sure if this configuration would be optimal. Alternative would be to do my Windows development on the host Windows 7 OS. What are your thoughts?

  • How to register a model in django-tagging anywhere not in the applications?

    - by culebrón
    Is it possible to register a model in django-tagging not in tagging app, nor in my app? The standard way is to edit apps/myapp/models.py this way: from apps import tagging tagging.register(MyModel) I want to keep both applications without changes, for example, to be able to pull new versions and just replace them. So I tried putting this into project settings.py, in the end, but of course this fails. from apps.myapp.models import MyModel from apps import tagging tagging.register(MyModel) (This fails when importing MyModel.) Any other way?

  • Recommend an algorithms exercise book?

    - by Parappa
    I have a little book called Problems on Algorithms by Ian Parberry which is chock full of exercises related to the study of algorithms. Can anybody recommend similar books? What I am not looking for are recommendations of good books related to algorithms or the theory of computation. Introduction to Algorithms is a good one, and of course there's the Knuth stuff. Ideally I want to know of any books that are light on instructional material and heavy on sample problems. In a nutshell, exercise books. Preferably dedicated to algorithms rather than general logic or other math problems. By the way, the Parberry book does not seem to be in print, but it is available as a PDF dowload.

  • Continuous Deployment with a C#/ASP.NET website?

    - by Amber Shah
    I have a website in C#/ASP.NET that is currently in development. When we are in production, I would like to do releases frequently over the course of the day, as we fix bugs and add features (like this: http://toni.org/2010/05/19/in-praise-of-continuous-deployment-the-wordpress-com-story/). If you upload a new version of the site or even change a single file, it kicks out the users that are currently logged in and makes them start over any forms and such. Is there a secret to being able to do deployments without interfering with users for .NET sites?

  • UI suggestions on how to display suggested tags for a given text to a user?

    - by Danny
    I am writing a web-app that uses a tagging system to organize the user's submitted reports. Part of it uses ajax to get suggestions for tags to present to the user based on the content of their report. I am looking for suggestions on how to present this information for the user. I'm not quite certain what a friendly way to do this would be. Edit: Well, most of the responses here seem to be focused on the user typing in keywords. The idea I'm trying to define here is more towards presenting the user a set of suggested keywords that they may accept or decline without having to type a tag in manually. (That option is of course still available to them) --------------------------- # say they can checkoff or select tags they like. | o[tag2] x[foo] o[moo] | | x[tag1] o[bar] | ---------------------------

  • C#: How to remove items from the collection of a IDictionary<E, ICollection<T>> with LINQ?

    - by Rosarch
    Here is what I am trying to do: private readonly IDictionary<float, ICollection<IGameObjectController>> layers; foreach (ICollection<IGameObjectController> layerSet in layers.Values) { foreach (IGameObjectController controller in layerSet) { if (controller.Model.DefinedInVariant) { layerSet.Remove(controller); } } } Of course, this doesn't work, because it will cause a concurrent modification exception. (Is there an equivalent of Java's safe removal operation on some iterators?) How can I do this correctly, or with LINQ?

  • QScrollBar Snap to value

    - by j3frea
    Hi all, I'm wanting to implement a scroll bar that snaps to particular values (like windows can snap to the edge of a screen). The idea is that as I drag the scrollbar down it snaps the bar to values as it approaches them. My scenario is displaying 3 chapters of text. I would like to be able to snap to the beginning or end of a chapter. Of course, to go to the start of the first chapter the scrollbar one can just scroll to the top and likewise with the end of the third chapter. So I'd like to draw two lines on the scrollbar to represent the start of the second and third chapters and then have the top and bottom of the scrollbar snap to those lines. So I'm really actually wanting to use this within a QTextBrowser but I can control a QTextBrowser with a "QSnapScrollBar" I just don't really know where to start. Any help would be greatly appreciated.

  • polymorphism pass instantiated base to deriver

    - by Eric
    I was wondering how to do this, consider the following classes public class Fruit { public string Name { get; set; } public Color Color { get; set; } } public class Apple : Fruit { public Apple() { } } How can I instantiate a new fruit but upcast to Apple, is there a way to instantiate a bunch of Fruit and make them apples with the name & color set. Do I need to manually deep copy? Of course this fails Fruit a = new Fruit(); a.Name = "FirstApple"; a.Color = Color.Red; Apple wa = a as Apple; System.Diagnostics.Debug.Print("Apple name: " + wa.Name); Do I need to pass in a Fruit to the AppleCTor and manually set the name and color( or 1-n properties) Is there an better design to do this?

  • Close resources before exiting JFrame and TCP communication in Java

    - by Oz Molaim
    1. I'm writing a chat based application on TCP communication. I'm using NetBeans and I want to add functionality to the default EXIT_ON_CLOSE when exiting JFrame. The reason of course is because I want to clean resources and end threads safely. How can I call a method that clear resources and only then close the JFrame safely and end the process. 2. I need to implement the server side. The server has List/HashMap/Queue of 'Socket' with their chat nick-names. Is there any simple design pattern to do it correctly because I don't want to re-invent the wheel. thanks.

  • Which build tool to teach?

    - by Helper Method
    While similiar questions have been asked, this one's focused on which is best/easiest to teach. I'm giving a weekly tutorial at my university focusing on data structures and algorithms. Fromn time to time I introduce tools which may prove helpful in future projects like JUnit, Mercurial, Eclipse etc.. I plan to show them some kind of build tool but I'm not sure which one to choose. I by myself have very little knowledge about build tools, except a little experience in using make. It's more the concept of a build tool I want to show them, not a special tool per se. Which would be the most easiest/future proof/whatever tool to show them? I've read a little bit about Gradle, which looks nice, but so far I think Ant could be a good choice (it's a Java course I'm giving).

  • Is there any sense in performing binary AND with a number where all bits are set to 1

    - by n535
    Greetings everybody. I have seen examples of such operations for so many times that I begin to think that I am getting something wrong with binary arithmetic. Is there any sense to perform the following: byte value = someAnotherByteValue & 0xFF; I don't really understand this, because it does not change anything anyway. Thanks for help. P.S. I was trying to search for information both elsewhere and here, but unsuccessfully. EDIT: Well, off course i assume that someAnotherByteValue is 8 bits long, the problem is that i don't get why so many people ( i mean professionals ) use such things in their code. For example in Jon Skeet's MiscUtil there is: uint s1 = (uint)(initial & 0xffff); where initial is int.

  • Bulk stop watching tickets on Lighthouse?

    - by T.J. Crowder
    Via the Lighthouse user interface, is there any way to bulk stop watching tickets? I have more than 150 tickets on a project I want to stop watching, and would just as soon not go into each and every one of them. I thought the bulk edit command might work, but there doesn't appear to be a watch keyword in the bulk edit stuff (which is fair enough, I'm not really editing the tickets). When I go to my profile, I can subscribe or unsubscribe to an entire project, but I'm not seeing a way to do this at the (bulk) ticket level. Looking at a list of the tickets I'm watching, I'm not seeing a way to do anything to all of them (other than the bulk edit command of course). Is there something I'm missing?

  • Flex4 Application state in a custom component

    - by itarato
    Hi, I'm porting my Flex3 app to Flex4 (FlashBuilder4). I get the whole new state concept, except one thing. In a custom component (separate mxml file) I'm using the main level Application's state. In Flex3 it was: <mx:State name="only_view_mode"> <mx:RemoveChild target="{myComponent.button1}" /> </mx:State> In Flex4 it should be something like that: <mx:State name="only_view_mode" /> and <mx:LinkButton id="button1" excludeFrom="???" /> My question is: how can I access to an Application state from a component? I checked the official reference (http://www.adobe.com/go/learn_flex4_alldocumentation_en) and Google of course but without any success. Thanks in advance

  • Compiling flex file into dll.

    - by Szpilona
    Hi, I've got a lexer created with flex (cygwin). Normally I compile it to an .exe file. For the newest project I need a lexer to use in a bigger C# program running on Windows XP. Of course I can execute a file using System.Diagnostics.Process. But it is not the best solution for me as I want that program to run on several machines. How can I create a dll under cygwin having the source code of the lexer? Thanks in advance... Szpilona

  • Extending LINQ classes to my own partial classes in different namespaces?

    - by sah302
    I have a .dbml file which of course contains the auto-generated classes based on my tables. I would however, like to extend them to my own classes. Typically I design such that each of my tables get their own namespace in their own folder containing all of their associated dao and service classes. So if I am dealing with a page that only has to do with 'customers' for instance, I can only include the customerNS. But when using LINQ I seem to be unable to do this. I have tried removing a default namespace from the project, I have tried putting the .dbml file into it's own folder with a custom namespace and then adding a 'using' statement, but no nothing works. I also saw the Entity Namespace, Context Namespace, and Custom Tool Namespace properties associated with the .dbml file and tried setting all these to names x and trying 'using x' in my other class to allow me to extend partial classes, but it just doesn't work. Is this possible or do I have to keep all extended partial classes in the same namespace as the .dbml file?

  • Subversion has --record-only for merges, how do I do the same in Git ?

    - by Paul Hammant
    I have a repo where 'master' is going in a certain direction, and a second branch 'foo' is going to be divergent for a couple of commits, then track all subsequent changes to 'master' after that. This is all by choice of course. In Subversion you could do a --record-only merge to mark things as "merge has happened" even though no actual changes were committed. i.e. this change the merge-tracking numbers in properties attached to directories in the target branch. I have had a play with.. git merge --no-commit master .. as something I may be able to tinker with before I do the commit, but it is making a hell of a mess of the target branch for part of the change in question (rename followed by delete). There must be an easier way.. ? Paul

  • CMIS explorer webapp

    - by Nicolas Raoul
    CMIS is a recently approved standard for accessing ECM repositories. My idea is to create a repository explorer using CMIS, under the form of an open source Java/JEE Web Application. The main interest would probably be for integrators, using it as a framework on which to quickly build repository access intranet/extranet applications. Of course, if such an open source project already exists, I would rather contribute to it rather than start a competing effort. So, does such an application/framework already exist? As open source? The only one I have found so far is chemistry-opencmis-test-browser, which is intended for tests and seems really inconvenient to extend for business use (no MVC, no IoC).

  • How to convert a DOM node list to an array in Javascript?

    - by Guss
    I have a Javascript function that accepts a list of HTML nodes, but it expects a Javascript array (it runs some Array methods on that) and I want to feed it the output of Document.getElementsByTagName that returns a DOM node list. Initially I thought of using something simple like: Array.prototype.slice.call(list,0) And that works fine in all browsers, except of course Internet Explorer which returns the error "JScript object expected", as apparently the DOM node list returned by Document.getElement* methods is not a JScript object enough to be the target of a function call. Caveats: I don't mind writing Internet Explorer specific code, but I'm not allowed to use any Javascript libraries such as JQuery because I'm writing a widget to be embedded into 3rd party web site, and I cannot load external libraries that will create conflict for the clients. My last ditch effort is to iterate over the DOM node list and create an array myself, but is there a nicer way to do that?

  • Fastest way to display a full calendar

    - by Aurélien Ribon
    Hello, I need to display a complete calendar (12 months, 31~ days/month) on screen. Currently, I'm using a 12-column grid, with each column filled with a "months" stackpanel. Each "month" stackpanel is filled with 31 (or less) day representations. Each day representation is composed of a DockPanel embedding three controls : a textblock to display the day letter a textblock to display the day number a textblock to display a short message Of course, performances are crushed down when I try to resize the window. Is there a useful trick to allow a fast display of many textblocks ?
