  • jQuery: How to collect values from sliders into simple object with id as keys

    - by Svish
    I have several jQuery UI Sliders and I want to collect their values. Thought it would be a simple task, but when I was going to do it I got stuck and not quite sure what to do anymore :p The object I would like to end up with should look something like this: { a: 80, b: 90, c: 20, ... } I can do it manually like this: var values = { a: $('#a').slider('value'), b: $('#b').slider('value'), c: $('#c').slider('value'), ... }; But that's a bit tedious, especially if I need to add or remove or rename. Was hoping I could do something with the map or each function or something like that, but I can't figure it out. Anyone have some clever ideas?

  • Spring & Hibernate SessionFactory - recovery from a down server

    - by MJB
    So pre spring, we used version of HibernateUtil that cached the SessionFactory instance if a successful raw JDBC connection was made, and threw SQLException otherwise. This allowed us to recover from initial setup of the SessionFactory being "bad" due to authentication or server connection issues. We moved to Spring and wired things in a more or less classic way with the LocalSessionFactoryBean, the C3P0 datasource, and various dao classes which have the SessionFactory injected. Now, if the SQL server appears to not be up when the web app runs, the web app never recovers. All access to the dao methods blow up because a null sessionfactory gets injected. (once the sessionfactory is made properly, the connection pool mostly handles the up/down status of the sql server fine, so recovery is possible) Now, the dao methods are wired by default to be singletons, and we could change them to prototype. I don't think that will fix the matter though - I believe the LocalSessionFactoryBean is now "stuck" and caches the null reference (I haven't tested this yet, though, I'll shamefully admit). This has to be an issue that concerns people.

  • Passing message over network

    - by Sylvestre Equy
    Hi, I'm currently trying to develop a message-oriented networking framework and I'm a bit stuck on the internal mechanism. Here are the problematic interfaces : public interface IMessage { } public class Connection { public void Subscribe<TMessage>(Action<TMessage> messageCallback); public void Send<TMessage>(TMessage message); } The Send method does not seem complicated, though the mechanism behind Subscribe seems a bit more painful. Obviously when receiving a message on one end of the connection, I'll have to invoke the appropriate delegate. Do you have any advice on how to read messages and easily detect their types ? By the way, I'd like to avoid to use MSMQ.

  • What are the key steps a Developer needs to go through to become a good Project Manager?

    - by adpd
    I am a full-time Developer who aspires to be a great technical Project Manager. What are the key steps that you think I need to go through to achieve that aspiration? I am interested in professional qualifications (e.g. PRINCE2, etc.), training courses, personality traits, experiences, tips and techniques that would improve my chances of being the best I can be. I would be interested in hearing if anybody has done this, and whether they are happy with their change from development or if they wished they had stuck to a development (and the reasons behind this decision).

  • LINQ, creating unique collection of a collection

    - by Wish
    I have class Vertex and a class Edge (Edge holds 2 properties - Vertex Source and Vertex Target); Edges and Vertexes are collected into lists Some example: A-->B // edge from vertex A to B B-->C // edge from vertex B to C C-->A // edge from vertex C to A A-->C // edge from vertex A to C -- this is two way edge So I would like to make IDictionary<Edge, bool> which would hold edges (A--B and B--A would be like 1), and bool - if it is two way or no. I need it because when I draw them now, it draws 2 arrows under one another. I would better make 1 arrow. So I'm pretty stuck right here... May anybody help me a bit ?

  • Android ImageButton / Custom-Button?

    - by user568306
    Hi everyone, I am new to android development. So far I could help myself in all matters by reading threads here on stackoverflow. Now I am stuck and need someones help. Unfortunately I am not allowed to post an image of a screenshot because I am a new mamber, so I try to descripe it. I have a Samsung Galasy S and the clock app that ships with it has an button called "+ Create alarm". I want to create a similar button for my app. I've been experimenting with ImageButton. I do know how to get that "+"-Icon onto an ImageButton, but only centered and without text. I guess this is a custom button. Does anyone know how to do this? Can I do it in xml or do I need to extend the view-class and make it my own view?

  • jQuery show/hide for FAQ using the next() function

    - by jon_brockman
    Maybe it's because it's Friday but I'm stuck on a simple problem. I'm building a FAQ page where a user clicks on a question, revealing the answer beneath it. I'm trying to get the next() function to just grab the next instance of an "answer" div but, despite not getting any JS errors, the hidden div isn't showing. Here's the code: .answer { display:none; } $("a.question").click(function(){ $(this).next(".answer").toggle(); }); <a href="#" class="question">Queston 1</a> <div class="answer">Answer 1</div> <a href="#" class="question">Queston 2</a> <div class="answer">Answer 2</div>

  • Assorted list of what's new in Delphi [Language, RTL, VCL]?

    - by utku_karatas
    Hi gents, As someone who's been stuck at the older versions of Delphi and upgraded to D2010 lately, I figure I still use the language, RTL and VCL features from the D5 era and refrain from using these new features as the documents on those are somewhat decentralized around the blogosphere. So I'd like to ask if there was an assorted list like what's new docs of Python's - clear and concise to the point. Btw, please no screencasts. They seem to be quite abundant lately (probably because of CodeRages) but I find them very unintuitive to learn from. Let's leave that docs in video format thing to RoR community, shall we :).

  • C# How to place a comma after each word but the last in the list

    - by user576712
    I totally new to C# and learning as I go. I am stuck on issue which I'm hoping an experienced programmer can help.

  • How can I select a value matching my input from a TypeAhead control using WWW::Mechanize?

    - by kyoob
    So ordinarily the element I want to pick from a list would be populated on a page and I'd just find it and pick it. But I'm dealing with a control that doesn't populate list elements until some input has been stuck into a text box, after which it gives me a list of recommendations. For an example of the kind of list I'm talking about think of Facebook's "People, Places, and Things" search field. I want to plug a string into this text box, select the same string from the list of recommendations, and submit the form. The issue I'm having right now is I can't seem to get Mechanize to even recognize the field is there. I examine a dump of $mech->find_all_inputs and it isn't listed. Is this kind of field just beyond Mechanize's jurisdiction?

  • Run Java Application as a Service

    - by Jason
    I would like to run a Java application as a service. Unfortunately, I am limited in that I can't use something like the Java Service Wrapper (which does appear to be an excellent tool). Is there any way of running an executable JAR, as a service, without relying on external applications? I currently have the service installed, but it fails to start. This is where I am getting stuck and I haven't been able to find anything on Google other than information about the JSW. Thanks.

  • [java] Threading socket handler for two sided communication in tcp port

    - by raven
    I want to make a chat which will be programed in java. one computer will host the server and the other one will initiate the socket [tcp port]. now from what I read there should be a loop that will constantly read the socket which means it will make the code stuck. I have a button that is 'actionperformed' on mouse release, I want to know if it will work along with the loops that constantly reads the socket so that it will also send the infromation I wrote. If I must thread it, I want to know if the run() method must be void because if I thread it it will mean creating a new class, and the whole GUI is one big class which includes a text area, and it's private. also how can I extract the information from the socket directly to the text area? lets say the textarea variable is called "chatOutput". thx :)

  • Get text when enter is pressed in a text box in wxPython

    - by Sam
    I have a (single line) TextCtrl. The user types data into this. When they press enter, the contents of the box need to be extracted so they can be processed. I can't figure out how to catch enter being pressed. According to the docs, with the style wx.TE_PROCESS_ENTER set on my TextCtrl, it should generate a wx.EVT_COMMAND_TEXT_ENTER event when enter is pressed in the box, which I could then catch. However, wx.EVT_COMMAND_TEXT_ENTER seems not to exist (I get "module has no attribute EVT_COMMAND_TEXT_ENTER), so I'm a bit stuck. Googling just gets a couple of hits of people complaining wx.EVT_COMMAND_TEXT_ENTER doesn't work, so I guess I need another way of doing it.

  • Exposing console apps to the web with Ruby

    - by Aaron
    I'm looking to expose an interactive command line program via JSON or another RPC style service using Ruby. I've found a couple tricks to do this, but im missing something when redirecting the output and input. One method at least on linux is to redirect the stdin and stdout to a file then read and write to that file asynchronously with file reads and writes. Another method ive been trying after googling around was to use open4. Here is the code I wrote so far, but its getting stuck after reading a few lines from standard output. require "open4" include Open4 status = popen4("./srcds_run -console -game tf +map ctf_2fort -maxplayers 6") do |pid, stdin, stdout, stderr| puts "PID #{pid}" lines="" while (line=stdout.gets) lines+=line puts line end while (line=stderr.gets) lines+=line puts line end end Any help on this or some insight would be appreciated!

  • Is it possible to open a pipe-based filehandle which prints to a variable in perl?

    - by blackkettle
    Hi, I know I can do this, ------ open(F,"",\$var); print F "something cool"; close(F); print $var; ------ or this, open(F, "| ./prog1 | ./prog2 tmp.file"); print F "something cool"; close(F); but is it possible to combine these? The semantics of what I'd like to do should be clear from the following, open(F,"|./prog1 | ./prog2", \$var); print F "something cool"; close(F); print $var; however the above clearly won't work. A few minutes of experimenting and googling seems to indicate that this is not possible, but I'd like to know if I'm stuck with using the `` to capture the output.

  • How do I set ORDER BY params using prepared PDO statement?

    - by Marlorn
    I'm having problems using params in the ORDER BY section of my SQL. It doesn't issue any warnings, but prints out nothing. $order = 'columnName'; $direction = 'ASC'; $stmt = $db->prepare("SELECT field from table WHERE column = :my_param ORDER BY :order :direction"); $stmt->bindParam(':my_param', $is_live, PDO::PARAM_STR); $stmt->bindParam(':order', $order, PDO::PARAM_STR); $stmt->bindParam(':direction', $direction, PDO::PARAM_STR); $stmt->execute(); The :my_param works, but not :order or :direction. Is it not being internally escaped correctly? Am I stuck inserting it directly in the SQL? Like so: $order = 'columnName'; $direction = 'ASC'; $stmt = $db->prepare("SELECT * from table WHERE is_live = :is_live ORDER BY $order $direction"); Is there a PDO::PARAM_COLUMN_NAME constant or some equivalent? Thanks!

    So i am working on a project and need some advice. I have a MySQL database that stores events, i know how to code this functionality in PHP but im just stuck of a few specifics. As the project that I am creating is a timetable, the most important attributes are the day of the event, starting time and finishing time. Once i have read this data from the MYSQL database using my PHP script, how do i go about inserting these events in to a html timetable? Lets say i have record like below in my events table: Event ID = 01 Event Day = Monday Event Start = 12:00 Event End = 14:00 How would I then put that into a html table, bearing in mind that i may have mutiple events for a day?
