  • Accessing html form input type=text using jquery from a windows forms webbrowser-control

    - by simply-tom
    I have two elements on my Windows Forms application: Webbrowser-Control Button Inside of the webbrowser-control I show a very simple html-form with two input type=text. I press the button and get access to both text fields. Last year at the Qt developer conference there was a quite good presentation: http://labs.trolltech.com/blogs/2009/04/17/jquery-and-qwebelement/ void highlightAllLinks() { QString code = "$('a').each( function () { $(this).css('background-color', 'yellow') } )"; view-page()-mainFrame()-evaluateJavaScript(code); } But I have to do this with .net and Windows Forms. Anyone knowing a good tutorial? Best regards,Tom

  • Should I be afraid of Linux server administration?

    - by markle976
    I've been trying to figure out what to focus on. I finally realized that the root of my quandary is that I am unsure about learning Linux server administration. I have been getting pretty good with PHP/MySQL and web development, but I am not very familiar with Linux. Is it hard to learn? What would I need to know in order to manage a LAMP stack? Also, which version is most used in enterprises? I think I have also hesitated to dive in because it seems like it is mostly used in small companies, but I guess that could be a good thing.

  • Powerpoint Add-In: Add a Button to PPT to SyntaxHighlight a Textbox

    - by Tigraine
    Hi Guys, I am trying to write an Add-In to Powerpoint that does basically one thing: Give users a Button somewhere to click, once they click on it the currently selected TextField should get syntax highlighted. The Syntax highlighting part is easy, I'm just having a real hard time finding some good information on how to successfully interact with Powerpoint from code. There are some MSDN articles highlighting how to add controls on document start or AddSlide, but no good information on how to extend the UI. Has anyone had some experience in this field and could point me to some resource that may help? Also, I am running Powerpoint 2007 while my customer may end up running PPT2003. How is the backwards compatibility of the Add-ins? greetings Daniel

  • Design for a machine learning artificial intelligence framework (community wiki)

    - by Lirik
    This is a community wiki which aims to provide a good design for a machine learning/artificial intelligence framework (ML/AI framework). Please contribute to the design of a language-agnostic framework which would allow multiple ML/AI algorithms to be plugged into a single framework which: runs the algorithms with a user-specified data set. facilitates learning, qualification, and classification. allows users to easily plug in new algorithms. can aggregate or create an ensemble of the existing algorithms. can save/load the progress of the algorithm (i.e. save the network and weights of a neural network, save the tree of a decision tree, etc.). What is a good design for this sort of ML/AI framework?

  • Tips on implementing a custom UITextView interface on the iPhone?

    - by Alex
    I am trying to implement a control to edit text that will display the text in multiple colors. None of the solutions I have attempted yet have been good enough. UITextView cannot accomplish this. All of the text must be the same color. Using CoreGraphics to draw the text does not allow the text to be selected. Using a UIWebView, DIV and PRE tags cannot be set to contentEditable on Mobile Safari. Currently playing with using an off-screen TEXTAREA and an on-screen DIV to show the rendered text. This works pretty well, except supporting all of these at the same time seems impossible: click-to-type, click-to-move-cursor, click-and-hold-select/copy/paste. Anyone have any tips on this predicament? I've been trying to find any preexisting library out there that will accomplish this in a good way, to no luck. I'm open to any ideas!

  • filling Bugzilla quip list

    - by Gerhard
    "Walking on water and developing software from a specification are easy if both are frozen." At the top of the Bugzilla page it prints a humorous/insightful quip. I have a list that I have been building up over the years as I encounter good one liners To brighten up my fellow developers days. What source did you use to fill your Bugzilla quip list. Online I have found only one interesting list. So maybe you can share some of the good quips from your bugzilla quiplist or maybe point me towards a interesting source online "I have an infinite capacity to do more work as long as you don't mind that my quality approaches zero - Dilbert."

  • Catching OutOfMemoryError

    - by dotsid
    Documentation for java.lang.Error says: An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch But as java.lang.Error is subclass of java.lang.Throwable I can catch this type of throwable. I understand why this is not good idea to catch this sort of exceptions. As far as I understand, if we decide to caught it, the catch handler should not allocate any memory by itself. Otherwise OutOfMemoryError will be thrown again. So, my question is: is there any real word scenarios when catching java.lang.OutOfMemoryError may be a good idea? if we catching java.lang.OutOfMemoryError how can we sure that catch handler doesn't allocate any memory by itself (any tools or best practicies)? Thanks a lot.

  • VS2010 add-in custom menu item in files of Solution Explorer

    - by NewProgrammer
    Hey guys, I need to create a custom menu item for Visual Studio 2010 Add-in in C#, but I have had no luck in coming with a solution anytime soon. I am aware that there was a similar post: http://stackoverflow.com/questions/2486818/visual-studio-add-in-adding-a-context-menu-item-to-solution-explorer But it did not help, as the blog follows the process through the integration package, and the video is done through VB. I had attempted to convert the VB syntax to the C# syntax, but about half way through the video, the Add-in methods has significantly changed from 2005 to 2010, as some of the methods have removed or changed. Is there any good tutorials on making a custom menu item on the Solution Explorer in the lastest Visual Studio in C#, and is there a good website that could be used as a reference for looking over the VS add-in API? I've used Microsoft's main website, however it is confusing and wordy, which is difficult to understand and find the methods, properties, or commands that I am looking for. Any help would be appreicated, Thanks in advance.

  • Application Interface between a PC and an embedded device

    - by sasayins
    Hi, How can I make an application interface so that a PC application can communicate to an embedded device like a POS terminal? Like for example, an embedded device like POS terminal that has an embedded linux as an OS. Then I want a PC application to communicate in that POS terminal and access its module hardware like for example its magnetic stripe reader. What implementation should I create in the device, should I use CORBA or something related in that technology so that a PC application can communicate in the POS terminal? Many thanks.

  • Is tcerl for Mnesia production ready? Is there any alternatives?

    - by Sanoj
    I would like to create a scalable web service using Mnesia as database. However Mnesia per default isn't scalable for persistent storgage since it is using Dets (which has a 2GB limit) as backend. I have seen discussions about extending Mnesia with MnesiaEx and use tcerl as backend. It sounds good and have showed good performance. However, I have seen in a talk about Tokyo Cabinet and CouchDB with Mnesia that there are some issues: issues with durability issues with memory leaks issues with crashes Is tcerl + Mnesia really production ready? And is there any other alternatives? How doe´s companies overcome these issues if they use Mnesia in bigger systems? Is there a working solution with Mnesia and Tokyo Tyrant that is working better?

  • Flow diagram in html/css

    - by viraptor
    Hi, is there some good way to create a flow / swimline diagram without resorting to scripting or tables? I'm talking about showing different hosts sending packets (so hosts on the X axis, time on the Y and arrows to the destination host). It seems like too much elements for tables (especially the arrows spanning multiple columns either way), but on the other hand, divs would be hard to position in the right place horizontally (they'd have to be basically aligned to a specified "column"). Is there any good way out? Any helper frameworks? (I don't want to do canvas stuff unless really needed)

  • How to call web service with Android

    - by BobbyShaftoe
    I am having a lot of trouble finding good information on how to call a standard SOAP/WSDL web service with Android. All I've been able to find are either very convoluted documents and references to "kSoap2" and then some bit about parsing it all manually with SAX. ... Ok, that's fine but it's 2008 so I figured there should be some good library for calling standard web services. The Web Service is just basically one created in NetBeans. I would like to have IDE support for generating the plumbing classes. I just need the easiest/most-elegant way to contact a WSDL based web service from an Android based phone. Thanks.

  • How to redirect if javaScript is disabled?

    - by Chris
    I have a site which relies heavily on javaScript. I created a mirror site, which has all the JS as well as all the elements that require JS removed. What is a good, easy way to redirect users to the mirror site if they don't have javaScript enabled? I tried this, but it doesn't seem very good: <noscript> <meta http-equiv="refresh" content="0; URL=nojs/index.php"> </noscript> I also tried to putting header-redirect into the meta tag, but that didn't work.

  • Entrepreneur Needs Programmers, Architects, or Engineers?

    - by brand-newbie
    Hi guys (Ladies included). I posted on a related site, but THIS is the place to be. I want to build a specialized website. I am an entrepreneur and refining valuations now for venture capitalsists: i.e., determining how much cash I will need. I need help in understanding what human resources I need (i.e., Software Programmers, Architects, Engineers, etc.)??? Trust me, I have read most--if not all--of the threads here on the subject, and I can tell you I am no closer to the answer than ever. Here's my technology problem: The website will include (2) main components: a search engine (web crawler)...and a very large database. The search engine will not be a competitor to google, obviously; however, it "will" require bots to scour the web. The website will be, basically, a statistical database....where users should be able to pull up any statistic from "numerous" fields. Like any entrepreneur with a web-based vision, I'm "hoping" to get 100+ million registered users eventually. However, practically, we will start as small as feasible. As regards the technology (database architecture, servers, etc.), I do want quality, quality, quality. My priorities are speed, and the capaility to be scalable...so that if I "did" get globally large, we could do it without having to re-engineer anything. In other words, I want the back-end and the "infrastructure" to be scalable and professional....with emphasis on quality. I am not an IT professional. Although I've built several Joomla-based websites, I'm just a rookie who's only used minor javascript coding to modify a few plug-ins and components. The business I'm trying to create requires specialization and experts. I want to define the problem and let a capable team create the final product, and I will stay totally hands off. So who do you guys suggest I hire to run this thing? A software engineer? I was thinking I would need a "database engineer," a "systems security engineer", and maybe 2 or 3 "programmers" for the search engine. Also a web designer...and maybe a part-time graphic designer...everyone working under a single software engineer. What do you guys think? Who should I hire?...I REALLY need help from some people in the industry (YOU guys) on this. Is this project do-able in 6 months? If so, how many people will I need? Who exactly needs to head up this thing?...Senior software engineer, an embedded engineer, a CC++ engineer, a java engineer, a database engineer? And do I build this thing is Ruby or Java?

  • Technique for ensuring HTML- and URL-encoding

    - by JW
    Has anyone implemented a good template system for ensuring that output is properly HTML-encoded where it makes sense? Maybe even something that recognizes when output should be URL-encoded or JSON-encoded instead? The lazy approach — just encoding all inputs — causes problems when you want to send those inputs to a database, or to a block of JavaScript code. So something a little smarter is needed. The tedious approach — putting the proper encoding function around each piece of data on the template — works, but it's easy for developers to forget to do it. Is there a good approach that makes it easy for developers, and ensures that the right encoding is done? I was listening to one of the SO podcasts, and Joel tossed out an idea about using typed data to enforce a difference between HTML-encoded strings and non-encoded strings. Maybe that could be a starting point. I'm looking more for a strategy than for an implementation in a particular language (although I'd be happy to hear about implementations that already exist and work).

  • Simple comet example using php and jquery

    - by Ray
    I have searched on google for hours without finding a good and simple example of the comet technique using PHP. I just need an example that uses a persistent HTTP connection or something similar. I dont want to use a polling technique because I have something like that set up and not only is it difficult to work with and manage its a big hog of resources. Also I am using IIS7 not Apache. A good example would be really helpful so I can move on from this ugly polling technique. ,Thanks

  • Star Rating widget for jQuery UI

    - by Roger
    I was introduced to the Star Rating widget for jQuery UI: http://orkans-tmp.22web.net/star_rating/ I was originally using this one: http://www.fyneworks.com/jquery/star-rating/ Is there any difference between using the two? Well trying to use the jquery UI one, I can't get the input buttons to show up as stars. I have these js and css files included: <script src="jquery-1.3.2.min.js" type="text/javascript"></script> <script src="jquery-ui-1.7.2.custom.min.js" type="text/javascript"></script> <script src="ui.stars.js" type="text/javascript"></script> <link href="ui.stars.css" type="text/css" rel="stylesheet" /> And for my code, simply: <form> Rating: <span id="stars-cap"></span> <div id="stars-wrapper1"> <input type="radio" name="newrate" value="1" title="Very poor" /> <input type="radio" name="newrate" value="2" title="Poor" /> <input type="radio" name="newrate" value="3" title="Not that bad" /> <input type="radio" name="newrate" value="4" title="Fair" /> <input type="radio" name="newrate" value="5" title="Average" checked="checked" /> <input type="radio" name="newrate" value="6" title="Almost good" /> <input type="radio" name="newrate" value="7" title="Good" /> <input type="radio" name="newrate" value="8" title="Very good" /> <input type="radio" name="newrate" value="9" title="Excellent" /> <input type="radio" name="newrate" value="10" title="Perfect" /> </div> </form> All the files and images are in the same folder. I've never used jquery UI before, so I'm not sure if all I need is that file. I'm not sure if it needs it either, the other star rating plugin I was using didn't require it. Anyone know what I'm missing anything?

  • Best practice to handle Parent Form Child Form relation using Presentation Model

    - by Rajarshi
    According to Presentation Model notes by Martin Fowler and also on MSDN documentation about Presentation Model, it is explained that the Presentation Model Class should be unaware of the UI class and similarly Business Model Class should be unaware of the Presentation Model class. The UI should databind extensively to the Presentation Model, the Presentation Model in turn will co-ordinate with one or more Domain/Business Model objects to get the job done. The Presentation Model basically presents the Domain Model data in a way to facilitate maximum data binding in UI, allowing the UI take as less decisions as possible and thus increase testability of Presentation behaviours. This also makes the presentation model class generic, i.e. agnostic of any particular UI technology. Now, consider there is a List form (say CustomerList) and there is another Root form (say Customer) and there is a Use Case of allowing to Edit a Customer from the CustomerList form on a button click. For simplicity of discussion, consider that some actions took place when Customer List is opened from menu (i.e. Customer menu clicked) and the Customer List has been shown from the Menu click event. Now as per the above Use Case, I need to open the Customer Root UI (single Customer) from the Customer List. How do I do that? Build necessary objects (BusinessModel, PresentationModel, UI) in click event of Edit button and call CustomerEdit UI from there? Build the CustomerEdit UI from Presentation Model Class and show UI from presentation model? this can be done in any of the two ways below - a. Create objects in the following sequence DomainModel-PresentationModel-UIForm b. Use Unity.Resolve(); Either ways, Presentation Model is violated as the P model now has to the refer the concrete UI assembly, where CustomerEdit is located. Also the P Model has to refer and use a WinForm directly making it less UI technology agnostic. Even though the violations are in theory and can be ignored, I would still seek the community's opinion about whether I am going wrong direction. Please suggest if there's a better way to call the Child Form from the List (Parent) Form. Rajarshi

  • Agile Development - Developer Qualification required, and Disadvantages of

    - by Everyone
    We have been using Agile on a project for 3 years now. Albeit I was new to scrum, it came to me easily enough. However we found it quite difficult to break any freshers into the scrumming process. One reason may have been that estimation for the future requires domain and technology depth that freshers lack. What, if any is the necessary qualification for a developer be part of an Agile team? What, in your experience, are drawbacks to Agile?
