  • Binding functions of derived class with luabind

    - by Anamon
    I am currently developing a plugin-based system in C++ which provides a Lua scripting interface, for which I chose to use luabind. I'm using Lua 5 and luabind 0.9, both statically linked and compiled with MSVC++ 8. I am now having trouble binding functions with luabind when they are defined in a derived class, but not its parent class. More specifically, I have an abstract base class called 'IPlugin' from which all plugin classes inherit. When the plugin manager initialises, it registers that class and its functions like this: luabind::open(L); luabind::module(L) [ luabind::class_("IPlugin") .def("start", (void(IPlugin::*)())&IPlugin::start) ]; As it is only known at runtime what effective plugin classes are available, I had to solve loading plugins in a kind of roundabout way. The plugin manager exposes a factory function to Lua, which takes the name of a plugin class and a desired object name. The factory then creates the object, registers the plugin's class as inheriting from the 'IPlugin' base class, and immediately calls a function on the created object that registers itself as a global with the Lua state, like this: void PluginExample::registerLuaObject(lua_State *L, string a_name) { luabind::globals(L)[a_name] = (PluginExample*)this; } I initially did this because I had problems with Lua determining the most derived class of the object, as if I register it from the StreamManager it is only known as a subtype of 'IPlugin' and not the specific subtype. I'm not sure anymore if this is even necessary though, but it works and the created object is subsequently accessible from Lua under 'a_name'. The problem I have, though, is that functions defined in the derived class, which were not declared at all in the parent class, cannot be used. Virtual functions defined in the base class, such as 'start' above, work fine, and calling them from Lua on the new object runs the respective redefined code from the 'PluginExample' class. But if I add a new function to 'PluginExample', here for example a function taking no arguments and returning void, and register it like this: luabind::module(L) [ luabind::class_("PluginExample") .def(luabind::constructor()) .def("func", &PluginExample::func) ]; calling 'func' on the new object yields the following Lua runtime error: No matching overload found, candidates: void func(PluginExample&) I am correctly using the ':' syntax so the 'self' argument is not needed and it seems suddenly Lua cannot determine the derived type of the object anymore. I am sure I am doing something wrong, probably having to do with the two-step binding required by my system architecture, but I can't figure out where. I'd much appreciate some help =)

    Hi guys, I am new in this area of writing extension for PHP, however I need to create a wrapper class for C++ to PHP. I am currently using PHP 5.2.13. I read this article http://devzone.zend.com/article/4486-Wrapping-C-Classes-in-a-PHP-Extension, a tutorial on how I could proceed to wrap C++ class to communicate with PHP Zend however it is written to for linux system. Do you guys have any article or advice on how I could proceed to write a wrapper class to communicate with PHP?

  • Refactor file copy in Visual Studio?

    - by Sapphire
    Does Visual Studio / Resharper support this? By refactor copy I mean to be able to enter new class name in some dialog, and to have the tool do all the refactoring (renaming) for you. No Copy of ... file names, and no error upon having two classes with same name in the project. Netbeans does this out-of-the-box :(

  • Hyperlinks to download files without stopping the current page load

    - by Evgeny
    I've got an ASP.NET page that takes a long time to download and returns partial results as it's loading (as per my previous question). On the page I have some links to download files, ie. the response headers contain "Content-Disposition: attachment", so that the browser doesn't navigate away from the page. However, if the user clicks one of these links while the page is still loading it stops loading - normal behaviour, but not what I want in this case. I can get around that by adding target=_"blank" to the links, but this momentarily opens a new window and the closes it again (once the browser realises it's an "attachment"). Is there any way to avoid having those links stop the current page load without this new window trick? JavaScript is OK.

  • How to implement service layer in Zend Framework?

    - by takeshin
    I'm looking for some good resources to learn how to implement internal service layer in Zend Framework. This is interesting post, but with no concrete code samples. Where to put service classes (/application/modules/modulename/services/?); How to autoload them (custom autoloader?) Most common services (user, authentication, cart, cache, feed?) Sample implementations (any github repos?) Good practices?

  • Abstract Forms using WinForms

    - by pm_2
    I’m trying to achieve a similar affect in a WinForms application as a master form does with ASP.NET. My initial thoughts on this were to create a base form and declare it as abstract, but the compiler doesn’t seem to let me do this. public abstract partial class Master : Form { public Master() { InitializeComponent(); } } So I have two questions: Why will the compiler not let me do this? Am I using the wrong syntax or is this a genuine restriction. Can anyone suggest a workaround or better way to do this? EDIT: InitializeComponent code: private void InitializeComponent() { this.components = new System.ComponentModel.Container(); this.mainMenu1 = new System.Windows.Forms.MainMenu(); this.Menu = this.mainMenu1; this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi; this.Text = "Master"; this.AutoScroll = true; }

  • Is restricting attributes to class or properties doable?

    - by Will Marcouiller
    I have two custom attributes defined like so: internal class SchemaAttribute : Attribute { internal SchemaAttribute(string schema) { Schema = schema; } internal string Schema { get; private set; } } internal class AttributeAttribute : Attribute { internal AttributeAttribute(string attribute) { Attribute = attribute; } internal string Attribute { get; private set; } } I would like to restrict the SchemaAttribute to classes, and the AttributeAttribute to properties. Is this doable?

  • Android Source Not Compilable?

    - by GuyNoir
    So I've been looking at code from various parts of the Android git, but when I try to load and compile many of them (camera, media player, etc) they reference classes and parts of the SDK that just aren't available even with my SDK version updated to 2.2. (for example the bitmap config option inNativeAlloc) Is there a reason that these are not in the SDK given out to developers?

  • getting around circular references in Delphi

    - by Tom
    Is there a way of getting around circular unit references in Delphi? Maybe a newer version of delphi or some magic hack or something? My delphi project has 100 000+ lines of code mostly based on singleton classes. I need to refactor this, but that would mean several months of "circular reference" hell :)

  • Asp.net mvc, entity framework, Poco - Architecture

    - by user1576228
    I have a "small" enterprise application, aspnet mvc 3 + entity framework with POCO entity and repository pattern. I structured the solution in 4 projects: POCO entities Domain model Services web application When the application performs a query on the database, use one of the services provided, the service uses the repository and the small classes, as a result I have some dynamic proxy objects that I would like to convert in my domain entities, before using them in mvc views, but I do not know how. Dovrebber be set as the translator? This approach is reasonable?

  • Why doesn't Apple make private APIs inaccessible?

    - by Howiecamp
    If Apple doesn't want developers using private APIs in the iPhone SDK, why don't they do something like mark the classes and/or methods with whatever the Objective-C equivalent of C#'s "internal" keyword? If the APIs are spread amongst multiple binaries, Apple could refactor them into dedicated private-API-only binaries to make this easier for them.

  • Are you a self taught programmer or did you take a programming course?

    - by workinprogress
    Lots of developers I know were self taught programmers including me. I was wondering how much of the developer community learned programming by taking a course in school or by experimenting, asking questions on forums, reading online articles, and just making it up as you go along? Post whether you were self taught or took classes, what language you program in, and anything else that may be interesting. P.S. Books count as self taught.

  • RESTful membership

    - by FoxDemon
    I am currentlly trying to design a RESTful MembershipsController. The controller action update is used only for promoting, banning, approving,... members. To invoke the update action the URL must contain a Parameter called type with the appropriate value. I am not too sure if that is really RESTful design. Should I rather introduce sepearate actions for promoting,... members? class MembershipsController < ApplicationController def update @membership= Membership.find params[:id] if Membership.aasm_events.keys.include?(params[:type].to_sym) #[:ban, :promote,...] @membership.send("#{params[:type]}!") render :partial => 'update_membership' end end end

  • Best way to set-up an iPhone project?

    - by wgpubs
    Looking for the best way to set-up an iPhone project in XCode ... namely: What is the preferred project template to start with (e.g View-Based or Windows-Based application)? What folder structure should I create in XCode to manage the project? For example, under "Classes" is it a preferred practice to add Models, Views and Controllers sub-folders? Any other best practices, tips, etc... would be appreciated. Thanks

  • Persisting a collection backed by viewstate in a CompositeControl

    - by tomfanning
    Maybe it's been a long day but I'm having trouble persisting a collection backed by the ASP.NET ViewState in a CompositeControl. Here's a simplified version: public class MyControl : CompositeControl { public Collection<MyObject> MyObjectCollection { get { return (Collection<MyObject>)ViewState["coll"] == null ? new Collection<MyObject>() : (Collection<MyObject>)ViewState["coll"]; } set { ViewState["coll"] = value; } } } public partial class TestPage : System.Web.UI.Page { protected void btn_Click(object sender, EventArgs e) { myControl1.MyObjectCollection.Add(new MyObject()); } } When the button is clicked, the event hander btn_Click executes fine, but the setter for MyObjectCollection never gets called, hence the new MyObject() never gets persisted. I think I'm just having a blonde moment. Anyone fancy helping out?

  • Has anyone here tried using the iSeries Python port?

    - by nearly_lunchtime
    I found http://www.iseriespython.com/, which is a version of Python for the iSeries apparently including some system specific data access classes. I am keen to try this out, but will have to get approval at work to do so. My questions are: Does the port work well, or are there limits to what the interpreter can handle compared with standard Python implementations? Does the iSeries database access layer work well, creating usable objects from table definitions?

  • Is ZendX still active (Specifically ZendX_JQuery) ?

    - by Doron
    I need to have an autocomplete functionality using jquery, and I've encountered ZendX_JQuery which has such functionality available. However, I've noticed that the entire ZendX_JQuery classes, are a bit old (the default jquery version is 1.3.2, and jquery ui 1.7.1). (see http://framework.zend.com/svn/framework/extras/branches/release-1.10/library/ZendX/JQuery.php) Should I use that instead of my own written code to include the jquery library and etc., and should I use the ZendX_JQuery_View_Helper_AutoComplete class for such functionality ?

  • rails ajax redirect

    - by badnaam
    Here is my use case I have a search model with two actions search_set and search_show. 1 - A user loads the home page which contains a search_form, rendered via a partial (search_form). 2 - User does a search, and the request goes to search_set, the search is saved and a redirect happens to search_show page which again renders the search_form with the saved search preferences. This search form is different than the one if step1, because it's a remote form being submitted to the same action (search set) 3 - Now the user does another search, and the search form is submitted via ajax to the search_set action. The search is saved and executed and now I need to present the result via rjs templates (corresponding to search_show). I am told that if the request is xhr then I can't redirect to the search_show action? Is that right? If yes, how do I handle this? Here is my controller class http://pastie.org/993460 Thanks

  • How do I replicate the functionality of selecting contacts in messaging app?

    - by Polyomino
    Android's messaging app, located in projects/platform/packages/apps/Mms.git has a class called RecipientsEditor. I would like to be able to create MultiAutoCompleteTextView that will filter contacts the same way, to make contact selection easy in my app. using the mms app is cumbersome since it uses internal apis and has everything split across classes. Has anyone made an easy way to do this?
