• CSS selector for the last occurrence of a class on a page

  - by snaken

  Is there a CSS selector for the last occurrence of a class on a page? Say i have this HTML <dd> <span> <a class="required" id="forename">foo</a> </span> </dd> <dd> <span> <a class="required" id="surname">bar</a> </span> </dd> Is there a CSS selector that would return the a tag with the ID of surname. Something like .required:last maybe? Will be using Prototype if that matters?

• Does <httpRedirect> in web.config work in a mono setup? Or is it IIS7 specific?

  - by Crystal

  We had some content restructure recently and I'd like to put in some redirect rules into web.config so bookmarks to the old pages can get routed to their new locations/pages. I tried using this approach: <location path="~/product/productA.aspx"> <system.webServer> <httpRedirect enabled="true" destination="~/product/category/productA.aspx" exactDestination="false" childOnly="true" httpResponseStatus="Permanent" /> </system.webServer> </location> But all I'm getting when I go to "http://www.oursite.com/product/productA.aspx" is our http 404 page. Am I doing something wrong, or is the httpRedirect tag in web.config not supported in mono? worked, but not ideal for what we want to achieve. Thank you :)

• I want to version control my entire slice

  - by Tom

  I'm renting a slice (i.e., a VPS) from Slicehost. I've a spent a day or two filling up /usr with my favorite packages, /etc with configs and init scripts, and so on. Now I want to: save this whole setup somewhere (e.g., to load onto another machine). see what changes I've made to which files revert changes, tag revisions, and all that other good version control stuff Saving a disk image gives me (1), but not (2) and (3). Using Subversion (svn import / svn://someotherhost) might give me all three, but I expect problems if I actually try to check a project out into / and maintain .svn directories in root-owned areas. And to load my setup onto a fresh slice, I'd need to install an svn client on it first. Is there a good way to do what I want to do?

• Cannot select/edit TineMCE-generated table

  - by Rakward

  I'm currently using TinyMCE edit in my drupal-website, problem is that beneath the editor, some of the table is sticking out. If I remove the height set by javascript with firebug, it looks fine, even after resizing. So I want to remove the height with JS, I've put this function at the end of my page: $('table#edit-body_tbl').removeAttr('style'); However nothing happens. I test the function in firebug's console, it works perfectly. Basically, the problem is the JS works, but it wont do anything if I simply load it at the end of the page, even in the document.ready function. The TineMCE script is loaded before my script so I should be able to select/edit/delete elements generated by it no? Does anybody know why or how I can force the page to really load my function in the end(currently it is right in front of the -tag)? Other functions in the script work, except this thing ...

• Why can I not view foreign language characters in my mysql DB?

  - by Chris

  I am inserting the following characters into my DB: ?? / ?? This is the meta tag on the page that is inserting the characters: <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> I have altered all the columns in my table that is holding the characters to be utf8_unicode_ci The foreign characters show up like so in the DB: 汉字 / 漢字 When I use a sql statement to display those foreign characters on a page, they display correctly again as: ?? / ?? I am guessing I have some setting that is not correct in my DB, since it stores it correctly, but does not display it correctly. What can i do to make the foreign language characters to display correctly in my DB?

• What is the equivalent of <composite-element> in Castle ActiveRecord?

  - by Daniel T.

  I have a TrackLog that has a collection of TrackPoints: public class TrackLog { public string Name { get; set; } public ISet<TrackPoint> TrackPoints { get; set; } } public class TrackPoint { public DateTime Timestamp { get; set; } public double Latitude { get; set; } public double Longitude { get; set; } } I'd like to map the track points as a collection of components, as this makes the most sense. According to the book NHibernate in Action, on page 187: Collections of components are mapped similarily to other collections of value type instances. The only difference is the use of <composite-element> in place of the familiar <element> tag. How would I do this using Castle ActiveRecord attributes?

• Flex: Why does setting scaleX/Y in mxml effect the components size but setting it in actionscript do

  - by ChrisInCambo

  Hi, I'm playing around with the scaleX/Y in the canvas tag and have noticed some strange behaviour. When I set scale in in mxml the width and height of the canvas are adjusted accordingly. For example if I have a canvas like this: <mx:Canvas width="1000" height="1000" scaleX="0.1" scaleY="0.1" /> The canvas now appears on screen to have a width and height of 100 and if inside my creationComplete callback I check the width and height property they are indeed 100. But if I do exactly the same thing except I set the scaleX/Y property from actionscript the canvas on screen appears to have a width and height of 100 as expected, but when I check the width and height property of the canvas they are still at the previous values of 1000. Could anyone help me understand what is going on and also tell me if there is any method that will refresh the width and height values so that they are correct? Thanks, Chris

• Custom format document option in visual studio. Formatting CSS tags.

  - by Batu

  Hi, When i work in VS2008, i use the Ctrl+K+D very often as it saves a lot of time. But in CSS files, this command formats the document in a way i don't quite like. For example when i auto format the document, .Foo { width:1px; height:2px; } However, i like to format tags this way, as it is much more easy to read (in my opinion): .Foo { width:1px; height:2px; } So, are there any way that i can implement this ? The "Tag specific options" feature seems to be the thing that i need, but i am not quite sure how to do this. Thanks.

• Rails i18n and routes in javascript

  - by StefanS

  Sometimes it would be really handy to have the Rails localization files available in JavaScript. Same is true for for the routes helpers. I found these two plugins which are exactly doing this: Exposing i18n to JavaScript: http://github.com/fnando/i18n-js Rails Routes in JavaScript: http://tore.darell.no/pages/javascript_routes My questions: Are there any other plugins / gems doing similar things like the two above? What's the right approach in Rails? Meta tag? Additional data- attributes? Thanks for any input!

• Bug when adding a sprite to 1 <s:State>

  - by lostincode

  I'm working within a skin for a button that has some <s:State> normal over In the tag, I'm drawing a circle private var theshape:Sprite; private function drawShape():void { theshape = new Sprite(); theshape.graphics.beginFill(0x666666); theshape.graphics.drawCircle(3,5,10); theshape.graphics.endFill(); //i then add it to a Spite Visual Element that's defined in mxml canv.addChild(theshape); } This works fine, until I try to control under which states that canv SpriteVisualElement appears. If I just add an includeIn like this <s:SpriteVisualElement id="canv" includeIn="over" /> I get a run-time error TypeError: Error #1009: Cannot access a property or method of a null object reference. Any ideas what the problem is, or a different way I can accomplish the same thing. What I need is to simply include the circle in the button when it's in the hover state.

• FBML in Rails views using Facebooker

  - by ewakened

  Hi all, I have successfully wired up a Facebook Connect application and everything is working fine. I can sign new users up with Facebook, or I can link existing users with Facebook. No problems there. However, now I am trying to add an Invite page, where a user can see which of their Friends have the application, and then show them a Facebook FMBL Multi Select form to invite friends into it. Here is the documentation for that FBML tag. http://wiki.developers.facebook.com/index.php/Connect/Integrating_an_Invite_Form_into_Your_Website#Creating_a_Full_Multi-friend_Selector_Request_or_Invite However, I cannot get this to work within my Rails view. Do I need to setup something special to use FBML in my Rails views? THIS IS NOT A CANVAS Application, meaning I want people to come to my site and not visit the page through facebook, but I feel like I am missing something. Thank you! Kent

• Storing links to internal content pages in ASP.NET MVC

  - by mare

  I'm using a route like this routes.MapRoute( "PageBySlug", RouteType.Regular, "{slug}", new {controller = "Page", action = "Display", slug = "Default"}, null ); to map request to ~/Some-Page-Slug to ~/Page/Display/Some-Page-Slug. When adding content, user can choose to link to existing pages to create references and I then store those links in this format in the datastore: "/Some-Page-Slug". When I run the app in Cassini and pull the link out from datastore and attach it to A tag it looks like this http://localhost:93229/Some-Page-Slug and this link works. But when running the application in virtual directory under some website in IIS, the attached link generates this URL http://localhost/Some-Page-Slug, when it should be http://localhost/virtualdir/Some-Page-Slug. Of course, this generates 404 error. How can I solve this to be universally useful and working under all circumstances? Should I store it differently in the database or should I transform it into correct form in my Views at runtime and how to do that?

• Jquery UI accordion question - how would you approach this?

  - by E.J. Brennan

  I am using jquery UI accordion control in one of my apps asp.net apps. The data for the accordion comes from a database, and each database record has an ID, a Title Field and a content field. The title is the heading, and the content is the data that shows up when the draw is opened... I'd like to be able to call my page like this: http://www.mywebsite.com/mypage.aspx?ID=123 and have it display all the data (as it does now), but then have the default 'drawer' of the accordion open to the section that corresponds to the ID number passed in on the url...there are about 50 sections on the page. Any suggestions on how to approach this? My questions is specific to the jquery accordion function, the rest I know. So where would be the best place to 'tag' the drawer with the unique ID's, and then what is the snippet of javascript code (I assume) that I would use 'open' that drawer based on the ID passed in?? Thanks!

• Can I make controls defined in my markup public instead of protected

  - by RoboShop

  Say I have a web site with a master page and an aspx page. In my ASPX page, I am pointing to my masterpage with the MasterType tag. <%@ MasterType VirtualPath="~/mymasterpage.master" % Say, I've defined a label in the markup of my master page. If you look at the designer code, this label should be something like this. protected global::System.Web.UI.WebControls.Label label1; Now in my content page, I would like to reference this label. If I type in this "Master.label1", the complier will complain that the control is inaccessible due to the protection level" and rightly so, as label1 is automatically defined as "protected". My question is, if I define controls in my markup page, is it possible to set these controls as public instead of protected? I do not see an attribute for it. thanks in advance.

• Programmatically get screenshot of page

  - by Ender

  I'm writing a specialized crawler and parser for internal use and I require the ability to take a screenshot of a web page in order to check what colours are being used throughout. The program will take in around ten web addresses and will save them as a bitmap image, from there I plan to use LockBits in order to create a list of the five most used colours within the image. To my knowledge it's the easiest way to get the colours used within a web page but if there is an easier way to do it please chime in with your suggestions. Anyway, I was going to use this program until I saw the price tag. I'm also fairly new to C#, having only used it for a few months. Can anyone provide me with a solution to my problem of taking a screenshot of a web page in order to extract the colour scheme?

• Sample the deltas between values using boost::accumulators

  I have a data set with N integers (say, 13, 16, 17, 20) where each next sample is incremented by some value (3, 1, 3 in this case) and I want to use boost::accumulators::accumulator_set to find various statistics of the second sequence. I want to be able to do something like this: accumulator_set< double, features< tag::mean > > acc; ... acc(13); acc(16); acc(17); acc(20); ...BUT sampling the differences instead of the actual values. How can I do that with accumulator_set without keeping track of the last value manually?

• Spring - MVC - Sanitize URL before redisplaying to the user

  - by Raghav

  In my application , a HTTP GET request URL to the application with script tag is getting redisplayed as it is although it fails the authorization. Example: http://www.example.com/welcome<script>alert("hi")</script> The issue is sanitizing external input entered directly into address bar by modifying existing GET URL. Spring redisplays the submitted URL as it is. Though the script does not get executed in the browser(FF), is there anyway to strip the URL of these values before displaying it back to the user Reference: Spring MVC application filtering HTML in URL - Is this a security issue?
