  • Pull news from an RDF Feed using Ruby and Nokogiri?

    - by Christian
    I would like to pull the titleand description fields from the newsfeed at http://www.tagesschau.de/newsticker.rdf to feed them to the Mac's Text-to-Speech engine. My search for a nice Ruby Gem to do this has brought me to Nokogiri, but all examples that "pull something out" of a given XML seem to be centered around CSS somehow. Does anyone have any idea how to save the titleand description fields in an array?

    - by Shefy Gur-ary
    I'm pushing a scene to the game I'm working on, after pressing a button in the main menu. This scene is a gameplayScene which should have two layers ad childs: boardLayer and hudLayer. for now I'm testing with the boardLayer, I'm using block to call the gameplayScene to close both itself and the boardLayer, but by the time I get there the retain count of both layer is 3 (seems to be increasing after setting the block to 2, and I'm not sure when it is going up to 3) What cause this, and how should it be handled?

  • In partial view: "The model item passed into the dictionary is of type"

    - by Dave
    I lack understanding of some basic MVC concepts, despite all my searching. I created an MVC project in Visual Studio, which contains the partial view _LogOnPartial.shtml. I just want to access information within the view pertaining to the user, to put in a user dropdown menu. When I try to put this at the top of the partial view cshtml page I get the above error: @model MyProject_MVC.Models.UserRepository When I try this I also get an error: @Html.Partial("_LogOnPartial", MyProject_MVC.Models.UserRepository) 'MyProject_MVC.Models.UserRepository' is a 'type', which is not valid in the given context

    This is how one can set them up: http://www.c-sharpcorner.com/uploadfile/rmcochran/commandpromptinstudiotoolsmenu01152008103357am/commandpromptinstudiotoolsmenu.aspx My problem is that I have got too many of them set up, and I now need a separate sub-menu or two to keep them organized. I could not figure out how to do that. Feel free to ask if something is not clear.

  • easy, straightforward way to package a python program for debian?

    - by Jeremiah Rose
    i'm having trouble navigating the maze of distribution tools for python and debian; cdbs, debhelper, python-support, python-central, blah blah blah .. my application is a fairly straightforward one - a single python package (directory containing modules and a __init__.py), a script for running the program (script.py) and some icons and menu items (.desktop files). is there a simple straightforward way to make a .deb file out of these, or should i brave the nonsensical tools listed above?

  • One-liner javascript to collect values from object graph?

    - by Kevin Pauli
    Given the following object graph: { "children": [ { "child": { "pets": [ { "pet": { "name": "fido" } }, { "pet": { "name": "fluffy" } } ] } }, { "child": { "pets": [ { "pet": { "name": "spike" } } ] } } ] } What would be a nice one-liner (or two) to collect the names of my grandchildren's pets? The result should be ["fido", "fluffy", "spike"] I don't want to write custom methods for this... I'm looking for something like the way jQuery works in selecting dom nodes, where you can just give it a CSS-like path and it collects them up for you. I would expect the expression path to look something like "children child pets pet name"

  • Applying styles to a GridView matching certain criteria

    - by NickK
    Hi everyone. I'm fairly new to ASP.Net so it's probably just me being a bit stupid, but I just can't figure out why this isn't working. Basically, I have a GridView control (GridView1) on a page which is reading from a database. I already have a CSS style applied to the GridView and all I want to do is change the background image applied in the style depending on if a certain cell has data in it or not. The way I'm trying to handle this change is updating the CSS class applied to each row through C#. I have the code below doing this: protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { GridViewRow row = e.Row; string s = row.Cells[7].Text; if (s.Length > 0) { row.CssClass = "newRowBackground"; } else { row.CssClass = "oldRowBackground"; } } In theory, the data from Cell[7] will either be null or be a string (in this case, likely a person's name). The problem is that when the page loads, every row in the GridView has the new style applied to it, whether it's empty or not. However, when I change it to use hard coded examples, it works fine. So for example, the below would work exactly how I want it to: protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { GridViewRow row = e.Row; string s = row.Cells[7].Text; if (s == "Smith") //Matching a name in one of the rows { row.CssClass = "newRowBackground"; } else { row.CssClass = "oldRowBackground"; } } It seems as if the top piece of code is always returning the string with a value greater than 0, but when I check the database the fields are all null (except for my test record of "Smith"). I'm probably doing something very simple that's wrong here, but I can't see what. Like I said, I'm still very new to this. One thing I have tried is changing the argument in the if statement to things like: if (s != null), if (s != "") and if (s == string.empty) all with no luck. Any help is greatly appreciated and don't hesitate to tell me if I'm just being stupid here. :)

  • A Beginners' Guide to Learning JavaScript?

    - by CloseDiamond
    There's a few mentions of Javascript newbies getting starting by checking out some of Douglas Crockford's work (http://stackoverflow.com/questions/11246/best-resources-to-learn-javascript), but none of his resources seem to be for those looking to learn from the ground up. Are there any suggestions for complete beginners regarding how best to learn JavaScript? Personally I have plenty of HTML and CSS experience, and some PHP (which would help learning JS), but for those that don't know any programming language what would you recommend?

  • Httpsession with Spring 3 MVC

    - by vipul12389
    I want to use httpsession in Spring 3 MVC..i have searched all the web and got this solution..at http://forum.springsource.org/showthread.php?98850-Adding-to-stuff-to-the-session-while-using-ResponseBody Basically, My application auto authenticates user by getting winId and authorizes through LDAP..(Its a intranet site) Here is the flow of the application, 1. User enters Aplication url (http://localhost:8082/eIA_Mock_5) it has a welcome page (index.jsp) Index.jsp gets winId through jQuery and hits login.html (through Ajax) and passes windowsId login.html (Controller) authenticates through LDAP and gives back 'Valid' String as a response javascript, upon getting the correct response, redirects/loads welcome page i.e. goes to localhost:8082/eIA_Mock_5/welcome.html Now, i have filter associated with it..which checks for is session valid for each incoming request..Now the problem is even though i set data on to httpsession, yet the filter or any other controller fails to get the data through session as a result it doesnt proceeds further.. here is the code..and could you suggest what is wrong actually ?? Home_Controller.java @Controller public class Home_Controller { public static Log logger = LogFactory.getLog(Home_Controller.class); @RequestMapping(value={"/welcome"}) public ModelAndView loadWelcomePage(HttpServletRequest request,HttpServletResponse response) { ModelAndView mdv = new ModelAndView();

  • How to handle when SSRS does not automatically update fields based on database query?

    - by badpanda
    So I am trying to change the number of fields in my dataset in SSRS and the refresh button is not picking up the added field from the SQL server. The query is definitely returning the correct data, as I have double checked in the server engine itself. Also, I have tried manually adding the field using the SSRS menu, but as soon as I execute it disappears. Any suggestions or similar experiences?
