  • Why is there a constructor method if you can assign the values to variables?

    - by Joel
    I'm just learning PHP, and I'm confused about what the purpose of the __construct() method? If I can do this: class Bear { // define properties public $name = 'Bill'; public $weight = 200; // define methods public function eat($units) { echo $this->name." is eating ".$units." units of food... <br />"; $this->weight += $units; } } Then why do it with a constructor instead? : class Bear { // define properties public $name; public $weight; public function __construct(){ $this->name = 'Bill'; $this->weight = 200; } // define methods public function eat($units) { echo $this->name." is eating ".$units." units of food... <br />"; $this->weight += $units; } }

  • Help with Event-Based Components

    - by Joel in Gö
    I have started to look at Event-Based Components (EBCs), a programming method currently being explored by Ralf Wesphal in Germany, in particular. This is a really interesting and promising way to architect a software solution, and gets close to the age-old idea of being able to stick software components together like Lego :) A good starting point is the Channel 9 video here, and there is a fair bit of discussion in German at the Google Group on EBCs. I am however looking for more concrete examples - while the ideas look great, I am finding it hard to translate them into real code for anything more than a trivial project. Does anyone know of any good code examples (in C# preferably), or any more good sites where EBCs are discussed?

  • Issue with converting PDF pages to images with ImageMagick's convert (and PHP)

    - by Joel L
    I'm trying to create a small web service to convert PDF files to a series of images. When I run convert /full/path/to/source.pdf full/path/to/target.jpg when connected to the (shared hosting, Linux) server via ssh, everything works correctly. When executing the same command through PHP's exec() function, only the first few pages of the PDF file get converted. Sometimes the remaining pages are 0-length jpg files, sometimes they don't appear at all. Also, the bottom area of the first pages is sometimes black, as if convert stopped half-way on the page. What could be causing this problem?

  • Hotkey to toggle checkboxes does opposite

    - by Joel Harris
    In this jsFiddle, I have a table with checkboxes in the first column. The master checkbox in the table header functions as expected toggling the state of all the checkboxes in the table when it is clicked. I have set up a hotkey for "shift-x" to toggle the master checkbox. The desired behavior when using the hotkey is: The master checkbox is toggled The child checkboxes each have their checked state set to match the master But what is actually happening is the opposite... The child checkboxes each have their checked state set to match the master The master checkbox is toggled Here is the relevant code $(".master-select").click(function(){ $(this).closest("table").find("tbody .row-select").prop('checked', this.checked); }); function tickAllCheckboxes() { var master = $(".master-select").click(); } //using jquery.hotkeys.js to assign hotkey $(document).bind('keydown', 'shift+x', tickAllCheckboxes); This results in the child checkboxes having the opposite checked state of the master checkbox. Why is that happening? A fix would be nice, but I'm really after an explanation so I can understand what is happening.

  • How do I write escape characters verbatim (without escaping) in C# using StreamWriter?

    - by Joel
    I'm writing a utility that takes in a .resx file and creates a javascript object containing properties for all the name/value pairs in the .resx file. This is all well and good, until one of the values in the .resx is This dealer accepts electronic orders. /r/nClick to order {0} from this dealer. I'm adding the name/value pairs to the js object like this: streamWriter.Write(string.Format("\n{0} : \"{1}\"", kvp.Key, kvp.Value)); When kvp.Value = "This dealer accepts electronic orders./r/nClick to order {0} from this dealer." This causes StreamWriter.Write() to actually place a newline in between 'orders.' and 'Click', which naturally screws up my javascript output. I've tried different things with @ and without using string.Format, but I've had no luck. Any suggestions?

  • Zend Framework-Do images, mp3s, scripts, etc, just go in public folder?

    - by Joel
    I guess these are all questions that everyone must just know, because I'm not seeing this in the documentation :-D I understand that the public folder is the folder that the world has access to. I know it is the case with the css folder, but in migrating a traditional php website over, will my /images folder, /js folder /mp3s, etc Will those all just also be public folders that will be accessed via the layout or view.phtml pages? Thanks!

  • Distributed version control systems merge easiness details

    - by Idsa
    I have just read Joel's blogpost concerning distributed version control systems and can't understand the main idea. He says that SVN thinks in terms of versions while Mercurial thinks in terms of changes. And, according to Joel, it solves merging problems. I heard this idea several times and still haven't conceived it. As I know, SVN's merging mechanism is based on changes (diffs) too. So what is the difference? I have no experience with distributed version control systems but I actively use SVN branching/merging and had no serious problems with it. Of course there are merging conflicts sometimes (when one piece of code was changed in both branches). But I see no way how this problem can be solved automatically by some kind of control version system.

  • Where do I put inline script in head with Zend Framework?

    - by Joel
    I'm reading the manual here: http://zendframework.com/manual/en/zend.view.helpers.html but I'm still confused. I have a script in my head that I'm converting to the layout/view for the Zend MVC: <script type="text/javascript"> var embedCode = '<object data="http://example.com" type="application/x-shockwave-flash" height="385" width="475"><param name="src" value="http://example.com" /><param name="allowfullscreen" value="true" /></object>' </script> I first tried to add it is an external file like this (in layout): $this->headScript()->appendFile('js/embeddedVideo.js')->appendScript($onloadScript); <head> <?php echo $this->headScript(); ?> </head> Didn't really work, but anyway, I'm wanting to just add the script and not add it as an external file. How do I do that? Thanks!

  • Where can I find a good book holder for decent sized programming books?

    - by Joel Marcey
    Suppose you have a book on a programming language and are trying to learn the language. You want to write the code that is given in the book in so you can learn by example while you read. But you hate holding the book on your lap and trying to type at the same time. I find that extremely uncomfortable. Someone recommended that I try using a music stand, but I figured the placement of that would be problematic since I would have to turn my head too much. Does anyone know of a good book holder that they can recommend that can sit next to your monitor so you can look at it while you type? Specifically, I am looking for one that can handle about a 600 page paperback book.

  • Can't draw UImage in UIView::drawRect

    - by Joel
    I know this seems like a simple task, which is why I don't understand why I can't get the image to render. When I set up my UIView, I do the following: myUiView.backgroundColor = [UIColor clearColor]; myUiView.opaque = NO; I create and retain the UIImage in the init function of my UIView: image = [[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"test" ofType:@"png"]] retain]; then my drawRect looks like this: - (void) drawRect:(CGRect) rect { [image drawInRect:self.bounds]; } Ultimately I'll be manipulating that UIImage via bitmap context, and then in drawRect create a CGImage out of the context, and render that, but for now I'm just trying to get it rendering a known image. I've been digging through this site, as well as the documentation. I've gone down the CG path and tried drawing it with CGContextDrawImage by following the numerous examples other people have posted, but that didn't work either. So I've come back to what seems to be the most straightforward way to draw an image, but it isn't working. Any help would be greatly appreciated. Thanks in advance.

  • Getting publish_stream extended permission from the user

    - by José Joel.
    I was ussing Facbook connect in my iPhone app, but in december the posts stopped working. After some research I found that i'm supossed to use stream.publish, something like: NSString *att = @"{\"bob\":\"i\'m happy\",\"caption\": \"User rated the internet 5 stars\", \"description\": \"a giant cat\"}"; NSDictionary *attachment = [NSDictionary dictionaryWithObject:att forKey:@"attachment"]; [[FBRequest requestWithDelegate:self] call:@"facebook.stream.publish" params:attachment]; Which i think it's correct, but the posts still don't work. Someone told me that i need to get publish_stream extended permission from the user, but i dont know how to do that.

  • NSTableView won't begin dragging rows if the mouseDown happens within the rect of an NSButtonCell.

    - by Joel Day
    I currently have an odd case where I need to be able to reorder rows in an NSTableView, but the only column happens to be an NSButtonCell. I'm trying to see how I can override NSButtonCell's mouse tracking in order to get it to behave in a way so that the NSTableView will begin dragging the row, but am not having much luck. Additional info that might affect the behavior: With this NSTableView, I am not allowing any rows to be selected, but I have forced mouse tracking to always occur for all cells. This is so that the button can still be clicked even though its row can never be selected. Thanks!

  • Flash Player scripting + IE8

    - by Joel Alejandro
    I've developed a small control bar for a Flash viewer generated by a third-party software. It has a First, Prev, Next & Last button, and a Zoom command. While Zoom works fine in all browsers, the navigation buttons seem to fail at Internet Explorer 8. I use at least two functions. This one locates the Flash object I want to manipulate: function getFlashMovieObject(movieName) { if (window.document[movieName]) { return window.document[movieName]; } if (navigator.appName.indexOf("Microsoft Internet")==-1) { if (document.embeds && document.embeds[movieName]) return document.embeds[movieName]; } else // if (navigator.appName.indexOf("Microsoft Internet")!=-1) { return document.getElementById(movieName); } } ...and any of these ones handles the frame navigation: var currentFrame = 0; function gotoFirst(id) { getFlashMovieObject(id + "Blueprints").Rewind(); currentFrame = 0; $("currentFrame").innerHTML = currentFrame + 1; $("frameTitle").innerHTML = frameTitles[id][currentFrame]; } function gotoPrev(id) { var movie = getFlashMovieObject(id + "Blueprints"); if (currentFrame 0) { currentFrame--; } movie.GotoFrame(currentFrame); $("currentFrame").innerHTML = currentFrame + 1; $("frameTitle").innerHTML = frameTitles[id][currentFrame]; } function gotoNext(id) { var movie = getFlashMovieObject(id + "Blueprints"); if (currentFrame < movie.TotalFrames() - 1) { currentFrame++; } movie.GotoFrame(currentFrame); $("currentFrame").innerHTML = currentFrame + 1; $("frameTitle").innerHTML = frameTitles[id][currentFrame]; } function gotoLast(id) { var movie = getFlashMovieObject(id + "Blueprints"); currentFrame = movie.TotalFrames() - 1; movie.GotoFrame(currentFrame); $("currentFrame").innerHTML = currentFrame + 1; $("frameTitle").innerHTML = frameTitles[id][currentFrame]; } Btw, that $ is MooTools, not jQuery. Anyway, IE dies on the movie.TotalFrames() call. What can I do to solve this? Keep in mind I need this to be done via JavaScript, as I cannot edit the SWF.

  • Visual Studio 2010 + ReSharper Not Working

    - by Joel
    I've installed ReSharper 5 on two installations of Visual Studio 2010 Professional. In both cases, ReSharper claims it has installed successfully - but Visual Studio doesn't recognize the extension. It doesn't show up in the Extensions Manager, doesn't appear in Help - About - Installed products, and can't be found anywhere else in the environment. I've tried install / uninstall of both Visual Studio and ReSharper, computer restarts, etc. Both machines have Visual Studio 2008 and ReSharper 5 works fine in these IDEs, and both machines are running Windows 7. I've found other people online with this issue, but no solutions. Anyone know how to fix this?

  • Folders without Namespaces C#, .Net, VS 2008

    - by Joel
    I'm working on an ASP.NET webapp using the MVP pattern, and as I'm organizing my files I'm wondering - are there conventions on folders within projects and how they relate to namespaces? I have a bunch of controls and a bunch of pages, and I was going to throw them into Controls and Pages folders with subfolders, but I didn't know if it was bad form to do this if I wasn't also going to seperate them out into namespaces. Thanks.

  • expand div when use clicks in text box?

    - by Joel
    I'd like to have a div expand to show contents when a user clicks their mouse in a text box to enter text. I haven't seen that around anywhere before. I know how to make things expand onClick, but can someone point me to what I'm looking for? Basically, I have an email signup box that I just want to show the input field for the email address, but if the user actually decided to get on the email list, that div will expand to also ask them for their name and zipcode. Thanks! I've got jquery already set for the email form now, so I'd like to expand on that if possible:

  • Comparison of collection datatypes in C#

    - by Joel in Gö
    Does anyone know of a good overview of the different C# collection types? I am looking for something showing which basic operations such as Add, Remove, RemoveLast etc. are supported, and giving the relative performance. It would be particularly interesting for the various generic classes - and even better if it showed eg. if there is a difference in performance between a List<T> where T is a class and one where T is a struct. A start would be a nice cheat-sheet for the abstract data structures, comparing Linked Lists, Hash Tables etc. etc. Thanks!

  • System.Interactive: Difference between Memoize() and MemoizeAll()?

    - by Joel Mueller
    In System.Interactive.dll (v1.0.2521.0) from Reactive Extensions, EnumerableEx has both a Memoize method and a MemoizeAll method. The API documentation is identical for both of them: Creates an enumerable that enumerates the original enumerable only once and caches its results. However, these methods are clearly not identical. If I use Memoize, my enumerable has values the first time I enumerate it, and seems to be empty the second time. If I use MemoizeAll then I get the behavior I would expect from the description of either method - I can enumerate the result as many times as I want and get the same results each time, but the source is only enumerated once. Can anyone tell me what the intended difference between these methods is? What is the use-case for Memoize? It seems like a fairly useless method with really confusing documentation.
