  • C++ polymorphism, function calls

    - by moai
    Okay, I'm pretty inexperienced as a programmer, let alone in C++, so bear with me here. What I wanted to do was to have a container class hold a parent class pointer and then use polymorphism to store a child class object. The thing is that I want to call one of the child class's functions through the parent class pointer. Here's a sort of example of what I mean in code: class SuperClass { public: int x; } class SubClass : public SuperClass { public: void function1() { x += 1; } } class Container { public: SuperClass * alpha; Container(SuperClass& beta) { alpha = beta; } } int main() { Container cont = new Container(new SubClass); } (I'm not sure that's right, I'm still really shaky on pointers. I hope it gets the point across, at least.) So, I'm not entirely sure whether I can do this or not. I have a sneaking suspicion the answer is no, but I want to be sure. If someone has another way to accomplish this sort of thing, I'd be glad to hear it.

  • Does UIScrollView have a special content view for making the scrolling possible?

    - by mystify
    I wonder if UIScrollView has got an "hidden" subview acting as an container for the content. If I scroll a scroll view, is that content view moved up/down in the scroll view? Or is the scrolling offset applied to the bounds of that UIScrollView instance? Or: Does UIScrollView use an additional view as container, or is all content added directly to the view? The documentation doesn't tell much about wether it has a content container or not.

  • What's the difference between DI and factory patterns?

    - by Anthony Short
    I have a class which depends on 3 classes, all 3 of which have other classes they rely on. Currently, I'm using a container class to build up all the required classes, inject them into one another and return the application. The simplified version of the container looks something like this: class Builder { private $_options; public function __construct($options) { $this->_options = $options; } public function build() { $cache = $this->getCache(); $response = $this->getResponse(); $engine = $this->getEngine(); return new Application($cache,$response,$engine); } public function getResponse() { $encoder = $this->getResponseEncoder(); $cache = $this->getResponseCache(); return new Response($encoder,$cache); } // Methods for building each object } I'm not sure if this would be classified as FactoryMethod or a DI Container. They both seem to solve the same problem in the same way - They build objects and inject dependencies. This container has some more complicated building methods, like loading observers and attaching them to observable objects. Should factories be doing all the building (loading extensions etc) and the DI container should use these factories to inject dependencies? That way the sub-packages, like Cache, Response etc, can each have their own specialised factories.

  • jQuery: select all DIV's nested under specific DIV

    - by Chris
    I have an architecture similar to this: <div id="container"> <div>stuff here</div> <div>stuff here</div> <div>stuff here</div> <div>stuff here</div> </div> I want to, using jQuery, hide the cursor when the mouse enters #container. However as the nested divs appear on top it doesn't quite work that way. How can I hide the mouse cursor when hovering over any of the divs within #container. Below is the cursor hiding code. $('#container').mouseover(function() { $(this).css({cursor: 'none'}); });

  • Help needed to align controls in a webpage

    - by Retrocoder
    I’m not too familiar with webpage design and am having a problem. I have the following datalist which is displayed ok but it is the section near the bottom that I am having with. I want the Hyperlink image to be on the same line as the “Details” text. Unfortunately the text appears below the Hyperlink control. Is there an easy fix to get what I want ? Should I be using the “div” mark-up instead of and ? <asp:DataList ID="dgDownloads" Width="100%" runat="server" EnableViewState="false" > <ItemTemplate> <tr> <td> <h3 class="mast3"><%# DataBinder.Eval (Container.DataItem, "Alias", "Reported by : {0}")%></h3> </td> <td> <h3 class="mast3"><%# DataBinder.Eval(Container.DataItem, "CreationDate", "Reported on : {0:dd/MM/yyyy}")%></h3> </td> </tr> <tr> <td colspan="2"> <h3 class="mast6"><%# ((System.Data.IDataRecord) Container.DataItem)["Heading"] %></h3> </td> </tr> <tr> <td colspan="2"> <asp:HyperLink CssClass="buttonStyle" ImageUrl="../images/bg/download.png" runat="server" NavigateUrl='<%#((System.Data.IDataRecord) Container.DataItem)["FileURL"] %>' /> <%# ((System.Data.IDataRecord) Container.DataItem)["Details"] %><ln/><br/><br/> </td> </tr> </ItemTemplate> </asp:DataList>

  • Masonry js won't bunch images vertically

    - by user1449737
    The images are being aligned horizontally correctly but they are all spaced out vertically.. Take a look here http://brstudios.co.uk/testing to see what I mean properly.. My mark up is as followed (simplified): <html> <head> <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript" src="http://masonry.desandro.com/jquery.masonry.min.js"></script> <script type="text/javascript" src="https://raw.github.com/desandro/imagesloaded/master/jquery.imagesloaded.min.js"></script> <script type="text/javascript"> var $container = $('.portfolio-container'); $container.imagesLoaded(function(){ $container.masonry({ itemSelector : '.break', columnWidth : 429 }); }); </script> <style type="text/css"> .break { float: left; width: 429px; margin: 10px 20px; } </style> </head> <body> <div class="portfolio-container"> <?php do { ?> <div class="break"> // Contents taken from MySQL // </div> <?php } while ($row_displayPosts = mysql_fetch_assoc($displayPosts)); ?> </div> </body> </html> I think part of it is working but as you can see by the link provided it isn't moving the elements together vertically. Does anyone have any pointers?

  • Best practice for handling memory leaks in large Java projects?

    - by knorv
    In almost all larger Java projects I've been involved with I've noticed that the quality of service of the application degrades with the uptime of the container. This is most probably due to memory leaks in the code. The correct way to solve this problem is obviously to trace back to the root cause of the problem and fix the leaks in the code. The quick and dirty way of solving the problem is simply restarting Tomcat (or whichever servlet container you're using). These are my three questions: Assume that you choose to solve the problem by tracing the root cause of the problem (the memory leaks), how would you collect data to zoom in on the problem? Assume that you choose the quick and dirty way of speeding things up by simply restarting the container, how would you collect data to choose the optimal restart cycle? Have you been able to deploy and run projects over an extended period of time without ever restarting the servlet container to regain snappiness? Or is an occasional servlet restart something that one has to simply accept?

  • Difference between MVC FilterAttribute and Filter

    - by zaaaaphod
    I'm trying to write my own custom AuthorizationAttribute that uses DI. I'm using the MUNQ IoC provider for it's speed and have decided to use constructor injection on all my classes as opposed to post instatiation property binding (because I prefer it). I'm trying to write a custom IFilterProvider that will use my IoC container to return requests for filters (so that I can map concrete classes using the container). I've come up with the following. public class FilterProvider : IFilterProvider { private readonly IocContainer _container; public FilterProvider(IocContainer container) { _container = container; } public IEnumerable<Filter> GetFilters(ControllerContext controllerContext, ActionDescriptor actionDescriptor) { var x = Enumerable.Union<Object>(_container.ResolveAll<IActionFilter>(), _container.ResolveAll<IAuthorizationFilter>()); foreach (Filter actionFilter in x) yield return new Filter(actionFilter, FilterScope.First, null); } } The above code will fail during the foreach because my objects that implement IAuthorizationFilter are based on FilterAttribute and not Filter My question is, what is the difference between Filter and FilterAttribute? I would have thought that there would have been a common link between them, unless I'm missing something. Another deeper question is, how come there is no IFilterAttributeProvider that would support IEnumerable GetFilters(...) Is there some other way that I should be using to resolve IAuthorizationFilter via my IoC container? Thank you very much for your help. Z

  • How to make a DIV auto height resizable even if the content is absolute?

    - by Tom
    Hi, i have a container div which is position:relative and the squares are position:absolute because i want to play with their positions. Like what you see, the container does not fit the content except if the squares are positioned in Relative, is there a solution for this? I don't want to just set the height for container because the squares are not static so i want something that resizes automatically. Thanks

  • synchronized in java - Proper use

    - by ZoharYosef
    I'm building a simple program to use in multi processes (Threads). My question is more to understand - when I have to use a reserved word synchronized? Do I need to use this word in any method that affects the bone variables? I know I can put it on any method that is not static, but I want to understand more. thank you! here is the code: public class Container { // *** data members *** public static final int INIT_SIZE=10; // the first (init) size of the set. public static final int RESCALE=10; // the re-scale factor of this set. private int _sp=0; public Object[] _data; /************ Constructors ************/ public Container(){ _sp=0; _data = new Object[INIT_SIZE]; } public Container(Container other) { // copy constructor this(); for(int i=0;i<other.size();i++) this.add(other.at(i)); } /** return true is this collection is empty, else return false. */ public synchronized boolean isEmpty() {return _sp==0;} /** add an Object to this set */ public synchronized void add (Object p){ if (_sp==_data.length) rescale(RESCALE); _data[_sp] = p; // shellow copy semantic. _sp++; } /** returns the actual amount of Objects contained in this collection */ public synchronized int size() {return _sp;} /** returns true if this container contains an element which is equals to ob */ public synchronized boolean isMember(Object ob) { return get(ob)!=-1; } /** return the index of the first object which equals ob, if none returns -1 */ public synchronized int get(Object ob) { int ans=-1; for(int i=0;i<size();i=i+1) if(at(i).equals(ob)) return i; return ans; } /** returns the element located at the ind place in this container (null if out of range) */ public synchronized Object at(int p){ if (p>=0 && p<size()) return _data[p]; else return null; }

  • MVC Validator.TryValidateObject does not validate custom atrribute, validateAllProperties = true

    - by nealsu
    When calling Validator.TryValidateObject with validateAllProperties = true my custom validation attribute does not get triggered. The ValidationResult does not contain an entry for my erroneous property value. Below is the model, attribute and code used to test this. //Model public class Model { [AmountGreaterThanZero] public int? Amount { get; set; } } //Attribute public sealed class AmountGreaterThanZero: ValidationAttribute { private const string errorMessage = "Amount should be greater than zero."; public AmountGreaterThanZero() : base(errorMessage) { } public override string FormatErrorMessage(string name) { return errorMessage; } protected override ValidationResult IsValid(object value, ValidationContext validationContext) { if (value != null) { if ((int)value <= 0) { var message = FormatErrorMessage(validationContext.DisplayName); return new ValidationResult(message); } } return null; } } //Validation Code var container = new Container(); container.ModelList = new List<Model>() { new Model() { Amount = -5 } }; var validationContext = new ValidationContext(container, null, null); var validationResults = new List<ValidationResult>(); var modelIsValid = Validator.TryValidateObject(container, validationContext, validationResults, true); Note: That the validation works fine and ValidationResult returns with correct error message if I use the TryValidateProperty method.

  • why we can't initialize a servlet using constructor itself?

    - by Reddy
    Why do we have to override init() method in Servlets while we can do the initialization in the constructor and have web container call the constructor passing ServletConfig reference to servlet while calling constructor? Ofcourse container has to use reflection for this but container has to use reflection anyway to call a simple no-arg constructor

  • Why isn't the inline element inheriting height from its children?

    - by jbarz
    I'm trying to make a rather complicated grid of images and information (almost like Pinterest). Specifically, I'm trying to inline position one set of <ul>s right after another. I have it working but one aspect is causing issues so I'm trying to ask about this small piece to avoid the complication of the whole problem. In order to horizontally align the images and their information we are using inline <li>s with other inline-block level elements inside of them. Everything works correctly for the most part except that the <li>s have almost no height. HTML and CSS is in JSFiddle here if you want to mess with it in addition to below: HTML: <div> <ul class="Container"> <li> <span class="Item"> <a href="#"><img src="http://jsfiddle.net/img/logo.png"/></a> <span class="Info"> <a href="#">Title One</a> <span class="Details">One Point One</span> </span> </span> </li> <li> <span class="Item"> <a href="#"><img src="http://jsfiddle.net/img/logo.png"/></a> <span class="Info"> <a href="#">Title Two</a> <span class="Details">Two Point One</span> </span> </span> </li> </ul> CSS: .Container { list-style-type:none; } .Container li { background-color:grey; display:inline; text-align:center; } .Container li .Item { border:solid 2px #ccc; display:inline-block; min-height:50px; vertical-align:top; width:170px; } .Container li .Item .Info { display:inline-block; } .Container li .Item .Info a { display:inline-block; width:160px; } If you check out the result in the jsfiddle link you can see that the grey background only encompasses a small strip of the whole <li>. I know that changing the <li> to display:inline-block solves this problem but that isn't feasible for other reasons. So first of all, I'm just looking to see if anyone understands why the inline <li> element doesn't have any height. I can't find anything in the spec that explains this. I know I can't add height to an inline element but any explanation as to why this is happening that might enable me to fix would be great. Secondly, if you inspect the elements using IE's Developer Mode you will see that although the background color is in the correct location, the actual location of the <li>'s bounding box is at the bottom of the container according to hovering over the element. I could deal with this problem if it was at the top in every browser but it apparently varies. NOTE: I don't really care about older browsers in this case but I don't use HTML5 or JavaScript positioning. Thanks.

  • How to use jquery .animate() to mock 'text-align:right'

    - by mrwienerdog
    I am building a very simple jquery menu. On hover, I have a menu on the right easing to the left margin of my menu container. This is easy, as the text is left aligned within said container. However, I also have a menu on the left, and because the links (left justified) are of differing length, the best I can do is adjust the padding to ease the text a uniform amount between links. Therefor, long link text goes to the right edge of the container, buy short text only makes it about half way. In reading about this, I have learned that you can not modify the text align property as it is non numeric. Is there any other way to do this? I of course tried to go with: $('#selector').css('text-align':'right') but that made the text jump to the right instead of ease. Is there any way to ensure all links ease to the rightmost margin of the container?

  • How is covariance cooler than polymorphism...and not redundant?

    - by P.Brian.Mackey
    .NET 4 introduces covariance. I guess it is useful. After all, MS went through all the trouble of adding it to the C# language. But, why is Covariance more useful than good old polymorphism? I wrote this example to understand why I should implement Covariance, but I still don't get it. Please enlighten me. using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Sample { class Demo { public delegate void ContraAction<in T>(T a); public interface IContainer<out T> { T GetItem(); void Do(ContraAction<T> action); } public class Container<T> : IContainer<T> { private T item; public Container(T item) { this.item = item; } public T GetItem() { return item; } public void Do(ContraAction<T> action) { action(item); } } public class Shape { public void Draw() { Console.WriteLine("Shape Drawn"); } } public class Circle:Shape { public void DrawCircle() { Console.WriteLine("Circle Drawn"); } } public static void Main() { Circle circle = new Circle(); IContainer<Shape> container = new Container<Circle>(circle); container.Do(s => s.Draw());//calls shape //Old school polymorphism...how is this not the same thing?

  • How to validate if all check boxes are ticked in jQuery?

    - by Jude
    I am a beginner in jQuery and I was wondering how to validate the form before submission specifically for check boxes. I am creating a simple check list form where my user would tick a check box if he finished that step. What I am planning to do is that, the script would prevent the form submission if there is an "unticked" checkbox and highlight it with a color. Here's my code : <!doctype html> <html> <head> <meta charset="utf-8"> <title>checkbox</title> <style> .error { background-color:#F00; } .valid { background-color:#0F0; } </style> <script type="application/javascript" src="http://code.jquery.com/jquery-1.8.2.min.js"> </script> <script type="application/javascript"> function validateAll() { $(".tick").change(function(){ if ($('.tick:checked').length == $('.tick').length) { $('#container').removeClass(); $('#container').addClass('error'); } else { $('#container').removeClass(); $('#container').addClass('valid'); } }); } </script> </head> <body> <div id="container"><input class="tick" id="option1" type="checkbox"></div> <div id="container"><input class="tick" id="option1" type="checkbox"></div> <input id="button" type="button" onClick="validateAll();" value="check"> </body> </html> So what I am trying to do here is when the user clicks the button, the script will highlight all the unchecked check box with red and highlight all checked with green. However, my script is not functioning. What is wrong with my script? Any suggestions on a more efficient way to do this?
