• In few words, what can be said about Func<>

  - by Richard77

  Hello, I've been seing Func< for sometime now, and I've manage to avoid it (for now). But, now it looks like I can't dodge it forever. For instance, I tried Dynamic Linq, but almost everything was in terms of Func<. I've tried one of my book (C# 2008/Deitel&Deitel) and also MSDN but I'm not getting it yet. They all jump straight in the subject. What can be said (in few words) about Func< Can I get some links on the web that can get me started on that matter? Thanks for helping

• Absolute URL Generation with Subdirectory in Rails

  - by Hulihan Applications

  Hey Guys - I'm trying to find an easy way(without having to write any plugins or overrides to Rails) to generate an absolute url to a rails application being in a subdirectory. This url is going to be generated for theme images, not links, so I can't url link_to or url_for. Here's an example of what I want to do: <%= theme_image("delete_icon.png", :theme => "my_theme") %> If my app is running at http://localhost, This would return: <img src="/themes/my_theme/images/delete_icon.png"> but If my app is running at http://localhost/myapp, This would return: <img src="/myapp/themes/my_theme/images/delete_icon.png"> Can anyone point me in the right direction to generate a dynamic, absolute url to a non-routed resource?

• JavaScript - Is it possible to get height from div in separate page?

  - by Kenny Bones

  Hi, I'm wondering, is it possible to collect the height of a specific div container from a separate page with JavaScript? I'm using jQuery btw and I'm in need of comparing heights of div containers. Edit: To clarify a bit more, I load content from a specific div in a separate page using jQuery. This content is faded into a different container with dynamic height. But in the small fraction of time before the content arrives, it shrinks down to it's min-height. What I've done so far is collecting the height of the container before and after the load. But it only works after I've loaded content once. Because I don't have the height before it's been loaded the first time.

• How do I fix this warning in my mx:request tag?

  - by invertedSpear

  I'm running an HTTPService with the following request: <mx:request xmlns=""> <view>{myViewStack.selectedChild.name}</view> </mx:request> The idea being to pass which child is selected on the viewstack to the php page, and then get that back so I can run some logic based on which child of the viewstack was selected at the time. Everything seems to work, but I get the following warning: Data binding will not be able to detect assignments to "name". This doesn't seem to be causing any trouble, but I know warnings usually mean that I am not following the best practice. How can I fix this? I don't really need this item to be bound, because the name will never change at runtime, but I don't know how else to include it in the request.

• Resizing Ubuntu x64 Server Partition with VirtualBox not reflected in OS

  - by daleyjem

  I've already resized my virtual disk with VirtualBox, but now need to extend the partition of my Ubuntu VM itself. I thought I was on my way with GParted live CD, but after I resize the "extended" filesystem partition, and then the child "lvm2 pv" filesystem partition to fill the unallocated space, df -h still shows the original disk size after I reboot into the VM. Any tips on this? I've scoured the webs tirelessly. Should I be resizing the boot (/dev/sda1) partition instead? Should I try to convert my lvm2 to ext4 or something? I'm lost on this. Note: VirtualBox hard disk is "dynamic". Specs: VBox 4.2.18 Ubuntu 12.04.2 amd64 Gparted 0.16.2-1b-i486

• Is it possible to have a .NET route that maps to the same place as a directory?

  - by Austin

  I'm building a CMS using WebForms on .NET 4.0 and have the following route that allows URLs like www.mysite.com/about to be mapped to the Page.aspx page, which looks up the dynamic content. routes.MapPageRoute("page", "{name}", "~/Page.aspx"); The problem is that I have a couple of folders in my project that are interfering with possible URLs. For example, I have a folder called "blog" where I store pages related to handling blog functionality, but if someone creates a page for their site called "blog" then navigating to www.mysite.com/blog gets the following error: 403 - Forbidden: Access is denied. You do not have permission to view this directory or page using the credentials that you supplied. Other similar URLs route correctly, but I think because .NET is identifying /blog as a physical location on the server it is denying directory access. Is there a way to tell IIS / .NET to only look for physical files instead of files and folders?

• Delphi 2010 - Why can't I declare an abstract method with a generic type parameter?

  - by James

  I am trying to do the following in Delphi 2010: TDataConverter = class abstract public function Convert<T>(const AData: T): string; virtual; abstract; end; However, I keep getting the following compiler error: E2533 Virtual, dynamic and message methods cannot have type parameters I don't quite understand the reason why I can't do this. I can do this in C# e.g. public abstract class DataConverter { public abstract string Convert<T>(T data); } Anyone know the reasoning behind this?

• refactor this javascript code

  - by nathanvda

  I have two click-events, that are nearly similar, but not quite. I am wondering how to refactor them best: $('.remove_fields.dynamic').live('click', function(e) { var $this = $(this); var after_removal_trigger_node = $this.closest(".nested-fields").parent(); trigger_removal_callback($this); e.preventDefault(); $this.closest(".nested-fields").remove(); trigger_after_removal_callback(after_removal_trigger_node); }); $('.remove_fields.existing').live('click', function(e) { var $this = $(this); var after_removal_trigger_node = $this.closest(".nested-fields").parent(); trigger_removal_callback($this); e.preventDefault(); $this.prev("input[type=hidden]").val("1"); $this.closest(".nested-fields").hide(); trigger_after_removal_callback(after_removal_trigger_node); }); As you can tell there is a fair bit of overlap. I am wondering what the best/nicest way would be to refactor this code.

• How to keep a floating div centered on window resize (jQuery/CSS)

  - by Jimbo

  Is there a way (without binding to the window.resize event) to force a floating DIV to re-center itself when the browser window is resized? To help explain, I imagine the pseudocode would look something like: div.left = 50% - (div.width / 2) div.top = 50% - (div.height / 2) UPDATE My query having been answered below, I wanted to post the final outcome of my quest - a jQuery extension method allowing you to center any block element - hope it helps someone else too. jQuery.fn.center = function() { var container = $(window); var top = -this.height() / 2; var left = -this.width() / 2; return this.css('position', 'absolute').css({ 'margin-left': left + 'px', 'margin-top': top + 'px', 'left': '50%', 'top': '50%' }); } Usage: $('#mydiv').center();

• Jquery How to use history plugin?

  - by Martijn

  In my web application I am using ajax and now I'd like the back and forward browser buttons to work. So I went looking for a jquery history plugin and found this one: http://stilbuero.de/jquery/history In my code I use a function to load a page: function loadDocument(id, doc) { $("#DocumentContent").show(); // Clear dynamic menu items $("#DynamicMenuContent").html(""); $("#PageContent").html(""); // Load document in frame $("#iframeDocument").attr("src", 'ViewDoc.aspx?id=' + id + '&doc=' + doc + ''); // Load menu items $("#DynamicMenuContent").load("ShowButtons.aspx"); } As you can see I want my pages to load within an Iframe. Can someone tell me how I can use a history plugin so that the brwoser buttons will work? I don't really care which plugin it is, as long as the browser buttons work. I prefer an easy to use plugin.

• [as3] Movieclip.width returns higher value than Movieclip stage on Width.

  - by Sawrb

  I have a Movieclip on stage with nested movieclips inside. All referenced at 0,0. None of the child movieclips load any dynamic content, animate or have Masked Layers. It does have an input textfield in one of the child MCs. The parent MC shows 280 px width, while it returns 313 px with a .width trace. There is no code that alters the .width value of the parent MC at run-time. And the ParentMC on stage is not scaled (it is at 100% width/height). Any pointers, to what could be the reasons for the discrepancy in .width values on stage and on run-time? Its breaking the scaling code that follows.

• Spring / Hibernate project with Tomcat and JQuery.

  - by Tiago

  Hi, I have a Dynamic Web Project that implements Spring and Hibernate using a Tomcat Server (v6). I'm lauching Tomcat with my Eclipse Galileo and I'm not getting any errors in the console but Tomcat is rendering my webpages randomly. The page just keep loading but without displaying anything, there's nothing on the console either. When I go in debug mode, it goes throught the right steps, everything seems alright. When I display the source code on the web browser (Firefox latest build) it shows me the right code that is needed to display the page I called. What am I not getting here? Plus when I stop Tomcat, it renders a part of the page. I'm wondering if JQuery could be the problem? The thing is that it's a collaborative project and that the others managed to run the web application in the most alright way. Please, share your experience with me.

• Sources from referenced projects are not deployed to Tomcat in Eclipse

  - by Steven De Groote

  Hi, I have setup a dynamic web project in eclipse with JSF in which I trust on code from another project (framework). Therefore, I added the framework project to the build path of the website project. So far so good, Eclipse recognises every class and the project builds without errors. Problem is though that when I do "run on server" to test it on tomcat 6.0.24, the application fails. I get ClassNotFoundException on every class from the framework project. Is this a bug or is some specific configuration necessary for this?

• Wordpress & Vanity User URLs

  - by st4ck0v3rfl0w

  Hi All, Was wondering if anyone had any smart approaches to creating dynamic vanity user urls upon user registration. My site basically uses emails as usernames. I have the regex to strip the text before the "@" symbol (e.g. "[email protected]" becomes "name") I would then like to take the "name" and create a vanity url (e.g. domain.com/name or name.domain.com) Any thoughts on how to accomplish this with Wordpress? I'm a pretty advanced Wordpress user and my first thoughts were to do the following Verify user registration Upon successful user registration create page name with username as the title (this would help me achieve the www.domain.com/username) Apply preset template to that page with the desired view Any and all thoughts are welcome.

• Include a repetitive chunk of HTML

  - by user146780

  I basically have a div on my site that always has the same stuff. However, this div is not present on all pages which is why I won't use the dynamic web template. I was wondering if it was possible for PHP to get the code from a document on the server and put in into the div? Ex: <div id="section... then my text file contains <p>hello</p> Basically I want PHP to put it into the div when the user sees it. If theres a smarter way of acheiving this I'd be open to it as well. Thanks
