  • Rails 3 routes and using GET to create clean URLs?

    - by Hard-Boiled Wonderland
    I am a little confused with the routes in Rails 3 as I am just starting to learn the language. I have a form generated here: <%= form_tag towns_path, :method => "get" do %> <%= label_tag :name, "Search for:" %> <%= text_field_tag :name, params[:name] %> <%= submit_tag "Search" %> <% end %> Then in my routes: get "towns/autocomplete_town_name" get "home/autocomplete_town_name" match 'towns' => 'towns#index' match 'towns/:name' => 'towns#index' resources :towns, :module => "town" resources :businesses, :module => "business" root :to => "home#index" So why when submitting the form do I get the URL: /towns?utf8=?&name=townname&commit=Search So the question is how do I make that url into a clean url like: /towns/townname Thanks, Andrew

  • jQuery colorbox plugin isn't loading inline content

    - by Summer
    Hi, I'm trying to use the jQuery colorbox plugin to show a little warning when a warning icon is clicked. Check out the problem: - Go to http://dev.imagineelection.com/browse/zip/10011 - Click on one of the warning icons (scroll down to see one). See how the colorbox that pops up is empty? I've tried to isolate the problem: - If you click "View Source" -- the div id="address-alert" is in there - If you click "View Generated Source" (for example, with Firefox Web Developer plugin) -- the div id="address-alert" has been taken out, but it has not been replaced inside the new div id="cboxCurrent" that colorbox has put at the top of the page The jQuery call I'm doing is: if (jQuery().colorbox) { $(".warning-class").colorbox({width:"50%", inline:true, href:"#address-alert"}); } What is going on? Why won't the inline content work?

  • How do I split up a long value (32 bits) into four char variables (8bits) using C?

    - by Jordan S
    I have a 32 bit long variable, CurrentPosition, that I want to split up into 4, 8bit characters. How would I do that most efficiently in C? I am working with an 8bit MCU, 8051 architectecture. unsigned long CurrentPosition = 7654321; unsigned char CP1 = 0; unsigned char CP2 = 0; unsigned char CP3 = 0; unsigned char CP4 = 0; // What do I do next? Should I just reference the starting address of CurrentPosition with a pointer and then add 8 two that address four times? It is little Endian. ALSO I want CurrentPosition to remain unchanged.

  • Opinions sought on the best way to organise classes in PHP

    - by jax
    I am pretty much set on using the Java package naming convention of com.website.app.whatever but am unsure about the best way of doing this in PHP. Option 1: Create a directory structure com/ mysite/ myapp/ encryption/ PublicKeyGenerator.class.php Cipher.class.php Xml/ XmlHelper.class.php XmlResponse.class.php Now this is how Java does it, it uses the folders to organize the heirarchy. This is however a little clumsy in PHP because there is no native support for it and when you move things around you break all includes. Option 2 Name classes using a periods for the package, therefore sames are just like in Java but can all be in the same directory making __autoload a breeze. classes/ com.mysite.myapp.encription.PublicKeyGenerator.class.php com.mysite.myapp.encription.Cipher.class.php com.mysite.myapp.xml.XmlHelper.class.php com.mysite.myapp.xml.XmlResponse.class.php The only real disadvantage here is that all the classes are in a single folder which might be confusing for large projects. Opinions sought, which is the best or are there other even better options?

  • How to programmatically deactivate the AirPort?

    - by mystify
    I want to make a small utility to programmatically deactivate the AirPort of my mac. I have networking problems which couldnt be resolved by expensive experts. I need to deactivate and reactivate the mac AirPort once every half hour. So a little utility which does that automatically would be great. I think I wouldn't need an UI for this either. Just the most simple possible kind of application to automatically stop and start the AirPort. Maybe even apple automator code?

  • Can't switch tab and replace value of an input and call a f() same time.

    - by marharépa
    Hi! I feel sorry of askin all my little thingys here, but i can't find the answer via google. :( I'd like to switch tabs, replace an input value and call a function by one click. THE JS: function ApplyTableId(id) { var $tabs = $('#tabs').tabs(); $('a.stat').click(function() { $tabs.tabs('select', 2); // switch to third tab }); $('tableId').val('ga:'+id); // replace the input with id=tableId's val getAccountFeed(); // call an other function } The another JS, which will be called by the first script: function getAccountFeed() { var myFeedUri = 'https://www.google.com/analytics/feeds/accounts/default?max-results=50'; myService.getAccountFeed(myFeedUri, handleAccountFeed, handleError); } This is what i want to call, and here is the HTML: TAB1: <a class="stat" onClick="return ApplyTableId(this.getAttribute('id'));" id="7777777" />asd</a> TAB3: <input type="text" value="asd" id="tableId"/> Please tell me, what i did wrong :(

  • How can I change my code in Excel 2003 to allow me to paste to multiple cells?

    - by PikeCoAL
    Ran in to a little problem. If I try to paste to multiple cells that are in the range in the code below, I get a run time error 13, type mismatch. The cells in the range may have data other than X but I only want the hyperlink to appear if the cell contains X. It works fine if I just type an X in the cell or if I paste to one cell at a time. I will have times when I want to paste other text to mutiple cells in this range. Thanks to Remnant for his help on the original code. This one last hurdle will put me in the clear. Thx. Private Sub Worksheet_Change(ByVal Target As Range) Dim rangeLimit As Range Set rangeLimit = Range ("B9:B37,C9:C37,D9:D37,E9:E37,F9:F37,G9:G37,H9:H37,I9:I37,J9:J37,K9:K37,L9:L37,M9:M37") If Not Intersect(rangeLimit, Target) Is Nothing Then If Target = "x" Or Target = "X" Then Target.Hyperlinks.Add Anchor:=Target, Address:="", SubAddress:="Exceptions!A1", TextToDisplay:=Target.Value End If End If End Sub

  • wxPython TreeCtrl without showing root while still showing arrows

    - by None
    I am making a python tree visualizer using wxPython. It would be used like so: show_tree([ 'A node with no children', ('A node with children', 'A child node', ('A child node with children', 'Another child')) ]) It worked fine but it shows a root with a value of "Tree". I made it so that it would create multiple roots but then learned that I wasn't allowed to do that. I reverted to the original code but used changed it from this: self.tree = wx.TreeCtrl(self) to this: self.tree = wx.TreeCtrl(self, style=wx.TR_HIDE_ROOT). It worked but it didn't show the little arrows on the side so you wouldn't know which nodes had children. Is there any way to hide the root node but keep the arrows. Note: I am on a Mac using Python version 2.5 and wxPython version 2.8.4.0.

  • Image gallery with a Lightbox in jQuery

    - by Alex
    Hi. I'd like to create a jQuery image gallery of showcased products. It will show one product image at a time, with Next/Previous arrows, and a brief name and price as overlay on the image. If users click it, it will go to the order page. It will have an icon to show a larger, modal version (Lightbox style) of the image with full description, price, and a link to a page to order it. In other words, it's an inline gallery, about 250px X 150px, with next/previous option, but also with a little icon to fire it up in a lightbox type modal window that can have links. Here's an example which doesn't have the inline gallery effect. Here's another, also missing the inline gallery. Is there such a beast as what I'm looking for? Thanks.

  • Question about C# properties

    - by Impz0r
    Hey there, i bumped the other day into a little problem regarding C#'s properties. Let's say i do have this setup: public class Point { public float X; public float Y; } public class Control { protected Point m_Position = new Point(); public Position { get { return m_Position; } set { m_Position = value; } // reorganize internal structure.. reorganize(); } protected reorganize() { // do some stuff } } This is all fine, but when it comes to usage, i could write something like: Control myControl = new Control(); myControl.Position.X = 1.0f; The thing is, my Control class wont recognize that the Position has been changed because set hasn't been called. So i guess my question is, is there a way to make Control aware of any Position changes? Thanks in advance! Mfg Imp

  • (Re)Enabling JavaScript debugger in IE7 with Visual Studio 2008

    - by masterik
    Visual Studio 2008 comes with nice javascript debugging features. But I have played a little with NetBeans debugger wich has installed an ugly Script Debugger from Microsoft to my IE... Normally IE should ask what do I want to use for debugging, but now I can't start debugging with Visual Studio, the Script Debugger is started automatically... After uninstalling the Script Debugger I can't debug in IE at all. Even attaching to iexplore.exe process doesn't helps... Has installed the Script Debugger again... :((((( How can I get back my Visual Studio debugging working in IE again?

  • Which programming language is easiest to get a junior position in?

    - by markle976
    I do not have a CS degree but I have lots of intermediate experience with many languages (PHP, C#, Objective-C, Java, VBScript, Actionscript, Javascript, Ruby, etc), mostly freelance or pastime. I have a little experience with Linux (Ubuntu), and a decent bit with Windows. When I look at different languages I find that am interested in most (except maybe VB), but I am not sure what to focus on. So what would be the easiest language to get a job in? Java? PHP? Or would it be easier to get a job as a Junior DBA if I learned Oracle or SQL Server in my spare time?

  • Jquery .html and .load

    - by Jack Pilowsky
    I'm trying to teach myself jQuery and I'm a little stomped with the load() method. I'm working on eBay listings. Yes, I know includes are not allowed on ebay. However, there is a workaround that has been around for a few years and ebay doesn't seem to be cracking down on it. var ebayItemID='xxxxxxxxxxxxxx'; // This is eBay code. I cannot edit it. <h1 id="title"> TO BE REPLACED</h1> $(document).ready(function(){ var link = "http://www.ebay.com/itm/" + ebayItemID + "?item=" + ebayItemID + &viewitem=&vxp=mtr"; var newTitle = $('#title').load(link + "#itemTitle"); $('#title').html(newTitle); }); What's the point of this. I want to show the item title on the description, but I want to do so dynamically,

  • Denying main links with .htaccess or anything else

    - by user1640660
    I'm using an encrypted php program with smarty template. I wanted to open links such as index.php?page=login to open with login.php, so I used Rewrite mode in .htaccesss, for example RewriteRule ^/*login.php$ /index.php?page=login [L] in a few pages there should be a query for errors such as RewriteRule ^/*support.php?(.+)$ /index.php?page=support&%{QUERY_STRING} [L] It works but I need to deny the main URLs so when users enters index.php?a=login manually nothing (or the main page) would show up and he should open the link only with /login.php. Is there a way to do this? A little help please...

  • Are protected constructors considered good practice?

    - by Álvaro G. Vicario
    I'm writing some little helper classes to handle trees. Basically, I have a node and a special root node that represents the tree. I want to keep it generic and simple. This is part of the code: <?php class Tree extends TreeNode{ public function addById($node_id, $parent_id, $generic_content){ if( $parent = $this->findNodeById($parent_id) ){ $parent->addChildById($node_id, $generic_content); } } } class TreeNode{ public function __construct($node_id, $parent_id, $generic_content){ // ... } protected function addChildById($node_id, $generic_content){ $this->children[] = new TreeNode($this->node_id, $node_id, $generic_content); } } $Categories = new Tree; $Categories->addById(1, NULL, $foo); $Categories->addById(2, NULL, $bar); $Categories->addById(3, 1, $gee); ?> My questions: Is it sensible to force TreeNode instances to be created through TreeNode::addById()? If it's so, would it be good practise to declare TreeNode::__construct() as private/protected?

  • two android threads and not synchronized data

    - by Sponge
    i have a (perhaps stupid) question: im using 2 threads, one is writing floats and one is reading this floats permanently. my question is, what could happen worse when i dont synchronize them? it would be no problem if some of the values would not be correct because they switch just a little every write operation. im running the application this way at the moment and dont have any problems so i want to know what could happen worse? a read/write conflict would cause a number like 12345 which is written to 54321 and red at the same time appear for example as 54345 ? or could happen something worse? (i dont want to use synchronization to keep the code as fast as possible)

  • can rails send data to browser chunk by chunk?

    - by Nik
    Hello all, I have a very large dataset (100,000) to be display, but any browser I tried that on including chrome 5 dev, it make them choke for dozens of seconds (win7 64bit, 4gb, 256gb ssd, c2duo 2.4ghertz). I did a little experiment by some_controller.rb def show @data = (1..100000).to_a end show.html.erb <% @data.each do |d| % <%= d.to_s % <% end% as simple as that it chokes the browsers. I know browsers were never built for this, so I thought to let the data come in chunk by chunk, I guess 2000 per chunk is reasonable, but I wouldn't want to make 50 requests each time this view is called, any ideas? It doesn't have to be chunk by chunk if it can be sent all at once. Best,

  • How to change the icon in the title bar in R?

    - by Jared
    I just installed R 2.11.0-x64 onto my Windows 7 Professional machine. With my previous installations of R (2.10.1 32 bit was the most recent) the little icon that appeared in the title bar and in the taskbar at the bottom of windows was the R "R." Now however, the icon almost looks like a small windows Task Manager. I know this isn't a code issue, but it affects me as I flip between windows. Is there a way to put the "R" icon back in there? Would it be an R setting or a Windows setting?

  • designing multi module J2EE application

    - by user728947
    Might be my question is abstract or out of context, but i am asking here since i have little idea how this happens. I am wondering how big application/ platform break down there application in to multiple module and how they able to manage modules dependencies. For example in some E-commerce application they tend to break down it in various modules like pricing,promotions,shipping.import/export and many more. when we develop those application we hardly think about the underlying modules and how they have been designed to provides functionalists. Most of those module are not web-applications but are standalone module and not deployed in the web-app as jar files. can any one help me to understand how they break up things or is there any standard way to do this.any help/resources to get insight will really be helpful

  • Flow Based Programming

    - by Software Monkey
    I have been doing a little reading on Flow Based Programming over the last few days. There is a wiki which provides further detail. And wikipedia has a good overview on it too. My first thought was, "Great another proponent of lego-land pretend programming" - a concept harking back to the late 80's. But, as I read more, I must admit I have become intrigued. Have you used FBP for a real project? What is your opinion of FBP? Does FBP have a future? In some senses, it seems like the holy grail of reuse that our industry has pursued since the advent of procedural languages.

  • Is there a server side API for Team Foundation Server?

    - by Ralph Shillington
    It would seem there is precious little documentation on programming against a TFS 2010 instance. What bits I have found, have next to nothing in the case of documentation beyond barebones listing of client access classes and their members, most likely autogenerated from the code comments. As I'm interested in building a silverlight client against TFS, I will need access to a server side API. Ideally the silverlight app will talk to my server (mainly for work items) and my server will in turn talk to the TFS server for the goods. Where is the doumentation (if any) for this kind of TFS integration?

  • How to access a website's url programmatically from within the page

    - by Jeff
    For work, I am working on a site that has a feature that lets users make custom instances of the site depending on who they want to show it to. So if they want to show their potential employer a little bit about themselves, they can send them a custom url, that has a uid on the end of it that tells the database what to show and what not to when the site is loaded up. Now, I need to be able to take the value that is on the end of the url, this unique uid that corresponds with their preferences in the db, accessable on run time. Meaning that when someone types in this custom url, I need to be able to show the name of the person whose portfolio is being viewed BEFORE password authentication takes place... If I could get the URL, I suppose I could parse through it to find the necessary UID...but how do I get the url? Maybe I am just missing something here, but if anyone has any thoughts or ideas, it would be appreciated!! Thanks

  • Grabbing Data From Controls In Code Behind

    - by MKell43
    Hopefully this is a pretty simple question for someone to answer. I have a drop down list control that I need to pull the value from in the code behind of the page, modify it and redisplay it. The modifying and redisplaying I've got no problem with, it's grabing the value from the drop down control. Examples in C# would be appreciated as this web app I've been handed is already coded that way. I'm pretty new to .Net so be gentle and I already did some searching via Google and a little bit on the site here, but couldn't find anything that stood out as being the direction to go in to do this.
