• Programmaticaly grabbing text from a web page that is dynamically generated.

  - by bstullkid

  There is a website I am trying to pull information from in perl, however the section of the page I need is being generated using javascript so all you see in the source is <div id="results"></div> I need to somehow pull out the contents of that div and save it to a file using perl/proxies/whatever. e.g. the information I want to save would be document.getElementById('results').innerHTML; I am not sure if this is possible or if anyone had any ideas or a way to do this. I was using a lynx source dump for other pages but since I cant straight forward screen scrape this page I came here to ask about it! If anyone is interested, the page is http://downloadcenter.trendmicro.com/index.php?clk=left_nav&clkval=pattern_file&regs=NABU and the info I am trying to get is the row about the ConsumerOPR

• WPF - Binding a variable in an already bound ListBox?

  - by Corey Ogburn

  I really don't know how to title this question, but I need some help with binding to a ListBox. I have an object, that contains (among other information) 2 properties that need to be bound in one ListBox. One of these is an ObservableCollection of objects, called Layers, and the other property holds an enum value of either Point, Line or Polygon, called SpatialType. These are to act as a legend to a map application. I have bound Layers to a ListBox, no problem, but inside the ListBox.ItemTemplate, I need to bind the single variable SpatialType to every Item in the ListBox. The problem I'm running into is that when I try to bind while inside the ListBox, the only variables I have access to are the properties of each Layer and I can't access any properties of the original bound class that holds the Layers (and the needed SpatialType property). What can I do to get that piece of information bound inside the ItemTemplate without messing up a good MVVM architecture?

• jQuery autocomplete works with a local string but not when the same String is called off the server

  - by Ankur

  This is related to the question I asked at http://stackoverflow.com/questions/2802948/how-to-make-an-ajax-call-immediately-on-document-loading My code is: $(document).ready(function(){ $.ajax({ type: "GET", url: "../AutoComplete", success: function(data) { var dataArray = data; alert(dataArray); $("#example").autocomplete(dataArray); } }); }); The value that is printed in the alert is: "Manuscript|Text|Information Object|Basketball|Ball|Sporting Equipment|Tarantula|Spider|Australian Spider|Cricket Player|Medieval Artefact|Person|Sportsperson|Leonardo Da Vinci|Country|Language|Inventor|Priest|Electronics Manufacturer|Object|letter|Artefact|governance model|Organism|Animal".split("|"); If instead I do this: $(document).ready(function(){ $.ajax({ type: "GET", url: "../AutoComplete", success: function(data) { var dataArray = "Manuscript|Text|Information Object|Basketball|Ball|Sporting Equipment|Tarantula|Spider|Australian Spider|Cricket Player|Medieval Artefact|Person|Sportsperson|Leonardo Da Vinci|Country|Language|Inventor|Priest|Electronics Manufacturer|Object|letter|Artefact|governance model|Organism|Animal".split("|"); alert(dataArray); $("#example").autocomplete(dataArray); } }); }); It works fine?

• What Data structure for Reputation Rules in C# (like stackoverflow)

  - by optician

  I am currently building a system which will have entities that will have scores like reputation etc.. I will have a service that will check for certain rules having been triggered, and will perform certain logic if they are triggered. Previously I have used say an Enum for doing this when I have only had to store an id and a description. public enum ShoppingCratCalculation { PartialCalculation = 1, CompleteCalculation =2 } But in this situation I want to carry more information, such as the modification to reputation, all in one place. I'm essentially asking what data structure would be best suited to storing this information, for each rule in the system. 1. Description = string ("User forgot to write a review") 2. DB id = int (23) 3. Rep score modification = int (-5) Maybe a little class (Rule) with these as properties , and then just a list? Does anyone have any best practice suggestions for this kind of struct?

• Eliminating static properties - What patterns do I have at my disposal?

  - by Jamie Dixon

  I currently have a type that I inject into my controllers that's used for getting and setting session data. I use this so that I can obtain relevant session information as _sessionData.Username rather than using Session["username"]. I'd like to use this session information across all of my views and would previously have done this by making the SessionData members static instead of injecting the SessionData class into my controller. I want to avoid using static members as well as having to pass the object to the view in each controller. What patterns best suit this type of scenario? What do you do to solve this same problem?

• Iphone & Web App synch

  - by Jack Welsh

  I am trying to build an Iphone App client for our CRM solution so our sales people would be able to access the information available in our CRM through an Iphone App. I am trying to find out what is the recommended approach to architect the application when it comes to the database. I am not sure where should the data reside, should I save a subset of the data on the iPhone, or should I just rely on webservices and pull the information I need from the database whenever I need it. Also, is there any best practices or frameworks to build such applications on the Iphone.

• How to use rel=canonical with Sitecore aliases?

  - by Mike G

  I have inherited a Sitecore architecture that is a mess from an SEO duplicate content POV. There are multiple aliases that have been created (and indexed by the search engines) for many of the 2nd tier pages of the site. Due to server issues, I am not able to 301 redirect these duped pages, so I would like to use the rel=canonical tag in an attempt to try and get Google/Bing to recognize the correct pages I would like to appear in the index. I have blocked the most extraneous duped pages with a robots.txt file, however, since Google/Bing have already spidered many of the duped pages, I need to keep them accessible to the spiders, BUT removed from the index. The catch is, since the duped pages are aliases (and don't really physically exist in Sitecore that I can find), I am not sure how to go about using rel=canonical - or if I even can in this situation..?

• What is the current legal status of magnet links?

  - by Moonwalker

  Prelude: I develop a cloud service which could be described as dropbox meets torrents and as side effect it enables distribution of arbitrary content via magnet links. Certain amount of magnet links will be displayed on the main website (I will be able to remove them one-by-one or ban users but no more). I will not be able to avoid magnets without complete rework of overall project architecture and either way it will hurt overall performance badly, probably making service meaningless. So my question is, what should I do, to avoid legal problems if my site in a nutshell is just a collection of magnet links? Privacy achieved via end-user encryption, so there is almost no access restrictions on the website. And anyway will help me any? Will hosting in particular country help me?

• asp.net webservice user management across pages

  - by nakori

  I'm developing a site that will display confidential readonly information, with data fetched from a WCF service. My question: What is the best approach to user management across different information pages. The service returns a collection with customer info after a secure login. My idea is to have a Customer object class that is stored in session. Is it possible to use things like HttpContext.Current.User.Identity.IsAuthenticated followed by HttpContext.Current.Session["UserId"] without using a database with role-based security? Would I be better off with a combination of local database, Linq to SQL or datasets rather than using just class objects for data fetched from service? thanks, nakori

• Most efficient way to save tile data of an isometric game

  - by Harmen

  Hello, I'm working on an isometric game for fast browsers that support <canvas>, which is great fun. To save information of each tile, I use a two-dimensional array which contains numbers representing a tile ID, like: var level = [[1, 1, 1, 2, 1, 0], [0, 1, 1, 2, 0, 1], [0, 1, 1, 2, 1, 1]]; var tiles = [ {name: 'grass', color: 'green'}, {name: 'water', color: 'blue'}, {name: 'forest', color: 'ForestGreen'} ]; So far it works great, but now I want to work with heights and slopes like in this picture: For each tile I need to save it's tile ID, height and information about which corners are turned upward. I came up with a simple idea about a bitwise representation of all four corners, like this: 1011 // top, bottom and left corner turned up My question is: what is the most efficient way to save these three values for each cell? Is it possible to save these three values as one integer?

• Follow the deadlines vs Do it right

  - by QuiteNothing

  I have been given a huge task of migrating few functionalities from jQuery to AngularJS. I have been pretty good at Angular by now. But I want to dive deep and create futuristic, sound architecture. BAs are seating on my neck, wanting to get my tasks as quickly as possible. I prefer doing something once and right vs keeping on patching existing functionalities. And with this attitude, I always keep working more than necessary. Am I missing something? Am I having right approach or am just not convincing enough BAs my point. What's the best approach, in your opinion Thank You :)

• How to design console application with good seperation of UI from Logic

  - by JavaSa

  Is it considered an overkill for console application to be design like MVC , MVP or N tier architecture? If not which is more common and if you can link me to simple example of it. I want to implement a tic tac toe game in console application. I have a solution which hold two projects: TicTacToeBusinessLogic (Class library project) and TicTacToeConsoleApplication (Console application project) to represent the view logic. In the TicTacToeConsoleApplication I've Program.cs class which holds the main entry point (public static void Main). Now I face a problem. I want the game to handle its own game flow so I can: Create new GameManager class (from BL) but this causing the view to directly know the BL part. So I'm a little confused how to write it in an acceptable way. Should I use delegates? Please show me a simple example.

• iOS Facebook Access Token To Get User Wall Feed (status)

  - by Felix

  [DISCLAIMER : None of the access token or ID below here are real] I've done research for three solid days and no result on how to get user wall feed(post). I have used https://graph.facebook.com/oauth/access_token?client_id=YOUR_APP_ID&client_secret=YOUR_APP_SECRET&grant_type=client_credentials and get the access token which is something like this access_token=454345994651138|bAMGfuW-ueNXGCahley7ga125HN and then https://graph.facebook.com/100005939123542/feed?access_token=454345994651138|bAMGfuW-ueNXGCahley7ga125HN It gives me general information such as user's likes, name, id, current city... but NOT user's wall posts. I've learned that there are three types of access token, which is App Token, User Token, and Page Token. In order to get user/feed by using graphAPI, I need to request to get User Token, but there's NO information in the lousy Facebook Doc! (Which frustrated me the most!) In order to generate the user access token, we need to set some permission, generate the access token, and GET the user's wall feed, which is in JSON format. My question is : How do I get the User Access Token in order to get user wall post in iOS Xcode?

• Mixing table per subclass and per hierarchy in hibernate

  - by Xelluloid

  In my database there are two three tables. The first one, table ABSTRACT, holds three columns id, type, someText This table contains all abstract information for the abstract class abstract. Now the two tables CONCRETEONE and CONCRETETWO contain all information for the concrete classes concreteOne and concreteTwo. Now I know I could use the table per subclass strategy from hibernate to create a mapping with inheritance. But as I have a column that marks the type of the concrete implementation could it be possible to create some mixed behaviour like a table per subclass strategy with an discriminator?

• Cherokee rule failover

  - by phretor

  I have a Cherokee virtual host configured as follows: 1st rule: "Directory /" -> HTTP Reverse Proxy 2nd rule: "Directory /" -> uWSGI I know the second rule is useless because it's never triggered. However, the first rule seldom returns a 504 Gateway Timeout error so I was thinking of failing over the second rule, yet I don't know how to achieve this. Is it possible? Unfortunately, I cannot use only one rule with load balanced information sources, because I use two different types of information sources (i.e., pure HTTP and WSGI).

• JSF, How to set a property in a different page/backing bean and then navigate to that page?

  - by kgrad

  I am using JSF 2.0 and attempting to pass values between different pages in my App. The setup is as follows: I have a page called userSelect that has a backing bean userSelectBacking. On this page I display a list of users that can be selected and submit using an h:commandbutton, when the page is submit the navigation goes to a userEdit page. I have a page called userEdit, that has a backing bean userEditBacking which displays the information for a user and allows that user to be edited. I would like to pass the user selected from the userSelect page into the userEdit page. I am currently using f:setPropertyActionListener to set the user in my userEdit backing from the userSelect page, however when I navigate to the userEdit page, it loses the information I set. is there a way that I can pass the values between the two pages/backing beans? thanks

• basic question with a dtd

  - by voodoomsr

  i need an element with the characteristics <!ELEMENT section ((comment*)|definition|(comment*))> but that is ambiguous, i get the next message in visual studio Multiple definition of element 'comment' causes the content model to become ambiguous. A content model must be formed such that during validation of an element information item sequence, the particle contained directly, indirectly or implicitly therein with which to attempt to validate each item in the sequence in turn can be uniquely determined without examining the content or attributes of that item, and without any information about the items in the remainder of the sequence. So how can i write correctly that? the correct structure is one definition surrounded by possibles comments elements.

• Array within Form collecting multiple values with the same name possible?

  - by JM4

  Good afternoon, I will first start with the goal I am trying to accomplish and then give a very basic sample of what I need to do. Goal Instead of collecting several variables and naming them with keys individually, I have decided to give in and use an array structure to handle all inputs of the same type and rules. Once I have the variables, I will validate against them and if 'ok' store them in a MySQL table. The table will hold consumer information and will need to store multiple rows of the same type of information. First Pass I will leave out the validation portion of this question because I feel I need to first understand the basics. <form action="?" method="POST" name="Form"> Member 1 First Name:<input type="text" name="MemberFirstName[]" /><br /> Member 1 Last Name: <input type="text" name="MemberLastName[]" /><br /> Member 1 Email: <input type="text" name="MemberEmail[]" /><br /> Member 2 First Name:<input type="text" name="MemberFirstName[]" /><br /> Member 2 Last Name: <input type="text" name="MemberLastName[]" /><br /> Member 2 Email: <input type="text" name="MemberEmail[]" /><br /> Member 3 First Name:<input type="text" name="MemberFirstName[]" /><br /> Member 3 Last Name: <input type="text" name="MemberLastName[]" /><br /> Member 3 Email: <input type="text" name="MemberEmail[]" /><br /> <input type="submit" name="submit" value="Continue" /> </form> I am hoping that each input given for First Name (a required field) will generate a unique key for that particular entry and not overwrite any data entered. Because I am carrying information from page to page (checkout form), I am turning the POST variables into SESSION variables then storing in a mysql database in the end. My hope is to have: <?php $conn = mysql_connect("localhost", "username", "password"); mysql_select_db("DBname",$conn); $sql = "INSERT INTO tablename VALUES ('$_SESSION[Member1FirstName]', '$_SESSION[Member1LastName]', '$_SESSION[Member1Email]', '$_SESSION[Member2FirstName]', '$_SESSION[Member2LastName]', '$_SESSION[Member2Email]', '$_SESSION[Member1FirstName]', '$_SESSION[Member3LastName]', '$_SESSION[Member3Email]')"; $result = mysql_query($sql, $conn) or die(mysql_error()); Header ("Location: completed.php"); ?> Where Member1, Member2, and Member3 values will appear on their own row within the table. I KNOW my code is wrong but I am giving a first shot at the overall business purpose I am trying to achieve and trying to learn how to code the right way. I am very, very new to programming so any 'baby advice' is greatly appreciated.
