  • Learning rails and AJAX. How do I load a div via ajax and then toggle hiding/showing it?

    - by Kevin L.
    I'm doing my first Ruby on Rails project. I am working on a project where the user can add a new message. Then they can add updates to this message like a thread. I've got it all written and now I'm going back and applying some AJAX. I want to show just the main message when the page first loads. Then when I click a link I want an AJAX event to fire that populates a div with all the updates to the message. Then I want this same link to toggle hiding and showing the div. I've made a submit button to fire the ajax and get back the updates using form_remote_tag. I've also created a separate link to toggle the hiding using $(div_id).toggle();. But now I'm stuck on how to combine these two things into one all purpose link. Thanks.

  • How to set utf8 in the auto-generated PHP code of flash builder 4 ?

    - by Mark
    HI, PHP problem here (I think): I've just created a Flex (Flash Builder) project with a datagrid linked to a database - the database is all utf8. When I run the project using the auto-generated code in flex4, the non-English part comes like ????? while the English part comes fine. The auto-generated PHP code uses mysqli. I've tried: $this->connection->set_charset('utf8'); or mysqli_query($this->connection,"SET NAMES utf8"); I also tried writing the code myself (I'm not a PHP guy): mysql_query("set names utf8"); was fine - but that's mysql and not mysqli (that's an "i" after the mysql) and I want to use the auto-generated code... any help is appreciated.

  • Browser based online game question

    - by Emre
    I am developing a small browser based game in asp.net. Think of a game room which has a capaticy of 22 players and players join the room by clicking a button. ( I am saving the number of players in the room in database) I need to call a method when the number of players in the room is 22. The problem is I don't know how to control the number of players in the room.

It's my first web project(school project) and I hope you all can help me.

  • the problem only happens when i try create a release...

    - by ace
    I'm sorry if im not presenting this right, but i trully cannot understand what the problem is. i have a project to hand in, a code of 600 lines defined within a main, .cpp, and header file. if i compile the project with just a debugger and no release, it's fine. when i create it with the release, the following error occurs, for every function!!! 1st error: |36|multiple definition of `countLines(int&, std::vector const&)'| 2nd error: |36|first defined here| if someone will allow me and i can send them the entire code, that would be awesome - i have to have this done within 3 hours.

  • Linkedin: Registering Application for both Web and Mobile

    - by VishwaKumar
    My project deals with both Web app and Mobile app. So before we can use Linkedin API's into our project we need to register our app with Linkedin according to this Quick Start. But for my situation where i use Linkedin API's for both web and mobile, Do i need to register two application with Linkedin. Or is there any other way to register a single application and use the same for both web and mobile? In the registration page i don't see any distinction for Web and Mobile, unlike facebook where a single application registered can be used for both web and mobile app. If anyone could point me to appropriate docs or pointers, it would be really helpful. Please forgive me for posting here as there wasn't any appropriate forum to choose from. Thank you.

  • Using different versions of the same assembly.

    - by AngryHacker
    I have a project where I simultaneously must use reports built in ActiveReports 2 and ActiveReports 6. Overall, it works ok, but some of the helper assemblies use the same name. For instance, to be able to export to PDF, both versions use an assembly called ActiveReports.PdfExport.dll. The corresponding assemblies are different, of course. Note that I don't access the ActiveReports.PdfExport.dll directly - this is handled by the ActiveReports runtime. I can't find a way to include both of them into the project. Is there a way? Is GAC the answer?

  • How to stop C# compile on first error in VS 2010 (VS 2008 macros don't work)!

    - by Ben Robbins
    At work we have a C# solution with over 80 projects. Is it possible in VS 2010 to automatically stop compilation as soon as an error is encountered rather than the default behaviour which is to continue as far as possible and display a list of errors in the error window? I'm happy for it to stop either as soon as an error is encountered (file-level) or as soon as a project fails to build (project-level). I'd also note that in VS 2008 we used macros similar to some of the answers below but they don't work in VS 2010 (at least I couldn't get them to as the environment events don't seem to fire in VS 2010).

  • Universal syntax file format?

    - by Isaiah
    Hey as a project to improve my programing skills I've begun programing a nice code editor in python to teach myself project management, version control, and gui programming. I was wanting to utilize syntax files made for other programs so I could have a large collection already. I was wondering if there was any kind of universal syntax file format much in the same sense as .odt files. I heard of one once in a forum, it had a website, but I can't remember it now. If not I may just try to use gedit syntax files or geany. thanks

  • Using *.html extension in dynamic URL's for SEO

    - by lostaman
    Hi all My situation is. I have a project planned to be built on ASP.NET MVC 2. And one of the major requirements is SEO optimization. A customer wants to use static-like URLs that end up with .html extension for this project that make URLs more SEO friendly. E.g. "mysite.com/about.html " or "mysite.com/items/getitem/5.html" etc. I wonder is there any benefit from SEO perspective to use .html extension in dynamic URLs? Are Google and other search engines rank work better with such URLs?

  • Visual C++ 2008: Finding the cause of slow link times

    - by ckarras
    I have a legacy C++ project that takes an annoyingly long time to build (several minutes, even for small incremental changes), and I found most of the time was spent linking. The project is already using precompiled headers and incremental compilation. I have enabled the "/time" command line parameter in the hope I would get more details about what is slowing the linker, and got the following output: 1>Linking... 1> MD Merge: Total time = 59.938s 1> Generate Transitions: Total time = 0.500s 1> MD Finalize: Total time = 7.328s 1>Pass 1: Interval #1, time = 71.718s 1>Pass 2: Interval #2, time = 8.969s 1>Final: Total time = 80.687s 1>Final: Total time = 80.953s Is there a way to get more details about each of these steps? For example, I would like to find if they are spending most time linking to a specific .lib or .obj file. Also, is there any documentation that explains what each of these steps do?

  • Boost singleton and undefined reference

    - by Ockonal
    Hello, I globally use singleton pattern in my project. To make it easier - boost::singleton. Current project uses Ogre3d library for rendering. Here is some class: class GraphicSystem : public singleton<GraphicSystem> { private: Ogre::RenderWindow *mWindow; public: Ogre::RenderWindow *getWindow() const { return mWindow; } }; In GraphicSystem constructor I fill the mWindow value: mWindow = mRoot->createRenderWindow(...); I cheked it, everything makes normally. So, now I have to use handler for the window in input system (to get window handle). Somewhere else in another class: Ogre::RenderWindow *temp = GraphicSystem::get_mutable_instance().getWindow(); GraphicSystem::get_mutable_instance().getWindow()->getCustomAttribute("WINDOW", &mWindowHandle); temp is 0x00, and there is segfault at last line (getting custon attribute). I can't understand, why does singleton returns undefined pointer for the window. All another singleton-based classes work well.

  • Having 'mvn deploy' in Hudson's build goals and the standard approach of releasing

    - by user68759
    I set up Hudson for my project with the build goals mvn clean deploy site:site, run a build every midnight and whenever there are new changes. One thing I have been wondering is whether I should include deploy in the build goals because it could happen that if I had just released version 1.0.0 of my project (I've changed the pom to be version 1.0.0 and committed it) but not yet increased the version number to 1.0.1-SNAPSHOT for several days, I could end up with multiple different 1.0.0 builds being deployed at different times. But I've seen people are using deploy in their Hudson's build goals - I wonder how they deal with this issue. What's the correct way of doing a release with Maven actually? Thanks for any pointers!

  • Metric to measure object-orientedness

    - by Jono
    Is there a metric that can assist in determining the object-orientedness of a system or application? I've seen some pretty neat metrics in the .NET Reflector Add-ins codeplex project, but nothing like this yet. If such a metric doesn't exist, would it even be possible or useful? There are the 3 supposed tenets of object-oriented programming: encapsulation, inheritance, and polymorphism; a tool that ranked programs against these might be able to show areas of a C# (or similar) code base where the whole object-oriented ideal was discarded, and perhaps how many bugs are associated with that area versus the rest of the project.

  • moving EDMX file System.Data.MetadataException: Unable to load the specified metadata resource.

    - by Dani
    I have a ASP.NET MVC 2 project. I've created edmx file on the class library project that holds the model. now I've created another class library called it shared and moved the edmx file over there. resolved some issues, everything compiles, but it can't find the connection string resource at runtime. I've copied the ConnectionString part of the Web.Config to the main file, the old class library app.config file and the new class library app.config file. Still get this error: System.Data.MetadataException: Unable to load the specified metadata resource. Line 75: public myProjdb() : base("name=myProjdb", "MyProjdb") in the MyProj.Designer.cs file. Any Idea how to resolve this issue ? Is there a better way to store connection string data ?

  • How do I disable maven build when using Maven 2.0 integration for eclipse?

    - by Stein G. Strindhaug
    How do I stop the "Maven 2.0 integration" plugin from running maven build, while keeping "build automatically" checked? I'm pretty sure it used to be some check box to disable maven build before, but after upgrading Ubuntu; eclipse seems to have been updated in the process, and now I cannot find any way to turn off the maven build. The maven build takes literally minutes (about 5 minutes or so), while just running java build used to finish in seconds. Is it no longer possible to disable it or have they just hidden it well? If it's not possible, will eclipse be able to compile my maven project without the plugin? (Trying to google for a solution the closes I got to an answer was several archives of this old post where the answer essentially were "You should be able to disable Maven builder in project preferences..." which doesn't really help because I cannot find any on/off settings there)

  • How can I add a .jar to my build path in Eclipse?

    - by Roman
    I try to do it the following way: Right click on the name of the project. Click on Build Path in the drop dawn menu. Click on "Configure Build Path" And then I do not know what to do. Should I select "Source", "Projects", "Libraries", "Order and Export"? In "Libraries" I have "Add JARs..." and "Add External JARs...". What should I select? (I have already a .jar file in the lib folder of my project.) ADDED: If I click on "Add JARs" in the "Libraries" tab, I see the "lib" sub-folder but if I go there I do not see my .jar file there (and I know that it is there).

  • SVN - ignoring files already in repository

    - by Alex
    I have a configuration file in my project which needs to be in the repository (so new developers get it when they checkout the project). Each developer might change some values in the file locally - these changes should not be committed and I don't want them showing in the synchronization menu (I'm using eclipse and subversive if it matters). Note that I can't just set the svn:ignore property since it only works on files that aren't under version control - but I do want to keep a base version of the file in the repository. How can I avoid the file showing in synchronization without deleting it from repository? EDIT: A better description - what I actually need is to be able to set a "read-only" property on the config file, so it can't be changed in the repository as long as the property is on. Do you know anything like this? Thanks

  • How to Embed/Link binary data into a C++ DLL

    - by CrimsonX
    So I have a Visual Studio 2008 project which has a large amount of binary data that it is currently referencing. I would like to package the binary data much like you can do with C# by adding it as a "resource" and compiling it as a DLL. Lets say all my data has an extension of ".data" and is currently being read from the visual studio project. Is there a way that you can compile or link the data into the .dll which it is calling? I've looked at some of the google link for this and so far I haven't come up with anything - the only possible solution I've come up with is to use something like ResGen to create a .resources file and then link it using AssemblyLinker with /Embed or /Link flags. I dont think it'd work properly though because I dont have text files to create the .resources files, but rather binary files themselves. Any advice?
