  • Python: Is there a way to reflectivly list all attributes of a class

    - by hhafez
    Given a class such as def MyClass text = "hello" number = 123 Is there a way in python to inspect MyClass an determine that it has the two attributes text and number. I can not use something like inspect.getSource(object) because the class I am to get it's attributes for are generate using SWIG (so they are hidden in .so :) ). So I am really looking for something equivalant to Java's [Class.getDeclardFields][1] Any help would be appreciated, otherwise I'll have to solve this problem with SWIG + JAVA instead of SWIG + Python.

  • Question regarding common class

    - by Rocky Singh
    I have following two classes: public class A : System.Web.UI.WebControls.Button { public virtual string X { get { object obj = ViewState["X"]; if (obj != null) return (string)obj; return null; } set { ViewState["X"] = value; } } protected override void OnLoad(EventArgs e) { X=2; } } and public class B : System.Web.UI.WebControls.TextBox { public virtual string X { get { object obj = ViewState["X"]; if (obj != null) return (string)obj; return null; } set { ViewState["X"] = value; } } protected override void OnLoad(EventArgs e) { X=2; } } As you must be seeing the class A and B have exactly the same code , my question is how can I make a common class for it and use these two classes.

  • Loading table sections when using headers

    - by Luis Tovar
    I cant seem to wrap my head around this. I have googled, and overstacked for hours now looking for examples that i can relate to. What I have is two arrays. The name of my first NSMutableArray is "showDates". I have 3 objects in here. Object 0: "Today, May 20th" Object 1: "Tomorrow, May 21st" Object 2: "Saturday, May 22nd" Then I have my second NSMutableArray named "showTimes" I have about 15 objects in there with strings in each object. ( i hope that makes sense? ) Each object is structured like this: Object 0: showID @"98022" eventID @"833" showTime @"1:30pm" showDate @"Today, May 20th" auditorium @"9" venue @"2991" Object 1: showID @"98222" eventID @"813" showTime @"2:30pm" showDate @"Tomorrow, May 21st" auditorium @"9" venue @"2991" Etc, etc, .... I have the headers working great in my tableView, but I cant seem to figure out how to add the objects in my "showTimes" array under the correct header. Any help would be greatly appreciated.

  • Question of using static_cast on "this" pointer in a derived object to base class

    - by Johnyy
    Hi, this is an example taken from Effective C++ 3ed, it says that if the static_cast is used this way, the base part of the object is copied, and the call is invoked from that part. I wanted to understand what is happening under the hood, will anyone help? class Window { // base class public: virtual void onResize() { } // base onResize impl }; class SpecialWindow: public Window { // derived class public: virtual void onResize() { // derived onResize impl; static_cast<Window>(*this).onResize(); // cast *this to Window, // then call its onResize; // this doesn't work! // do SpecialWindow- } // specific stuff };

  • Post Loading ads from Google Admanager

    - by Prem
    I have changed code around to basically load an add the bottom of the page in a hidden div and attached an onload event handler that called document.getElementById(xxx).appendChild() to take the hidden ad and move it into the right spot in my page. This works GREAT.. however when the ad is a text ad it AFTER i move the ad there is nothing in the rendered Iframe. I did tests to see what it looks like before i move it and sure enough the text links load in the IFRAME but the second i do the appendChild call to move the div that contains the ad i seem to loose the contents of the Iframe. Any ideas whats going on <div id="myad" style="display: none;"> GA_googleFillSlot("MyADSlotName"); </div> <script> window.onload = function() { // leader board document.getElementById('adplaceholder').appendChild(document.getElementById('myAd')); document.getElementById('myAd').style.display = ''; </script

  • Problem with IE 6 page loading.

    - by Puneet Dudeja
    I have a website which works fine in all browsers except in IE6. The pages content is inside a div loaded with a background image. The page layout gets very nasty and image does not load when the page is opened for first time, but when the same page is opened for the second time and any subsequent times, then it loads perfectly. This scenario is with every page in the site. Please help.

  • Choosing a design pattern for a class that might change it's internal attributes

    - by the_drow
    I have a class that holds arbitrary state and it's defined like this: class AbstractFoo { }; template <class StatePolicy> class Foo : public StatePolicy, public AbstractFoo { }; The state policy contains only protected attributes that represent the state. The state might be the same for multiple behaviors and they can be replaced at runtime. All Foo objects have the same interface to abstract the state itself and to enable storing Foo objects in containers. I would like to find the least verbose and the most maintainable way to express this.

  • Extjs - Loading Grid when call

    - by Oxi
    I have form and grid. the user must enter data in form fields then display related records in the grid. I want to implement a search form, e.g: user will type the name and gender of the student, then will get a grid of all students have the same name and gender. So, I use ajax to send form fields value to PHP and then creat a json_encode wich will be used in grid store. I am really not sure if my idea is good. But I haven't found another way to do that. The problem is when I set autoLoad to true in the store, the grid automatically filled with all data - not just what I asked for - So, I understand that I have to set autoLoad to false, but then the result not shown in the grid even it returned successfully in the firebug! I don't know what to do. My View: { xtype: 'panel', layout: "fit", id: 'searchResult', flex: 7, title: '<div style="text-align:center;"/>SearchResultGrid</div>', items: [ { xtype: 'gridpanel', store: 'advSearchStore', id: 'AdvSearch-grid', columns: [ { xtype: 'gridcolumn', dataIndex: 'name', align: 'right', text: 'name' }, { xtype: 'gridcolumn', dataIndex: 'gender', align: 'right', text: 'gender' } ], viewConfig: { id : 'Arr' ,emptyText: 'noResult' }, requires: ['MyApp.PrintSave_toolbar'], dockedItems: [ { xtype: 'PrintSave_tb', dock: 'bottom', } ] } ] }, My Store and Model: Ext.define('AdvSearchPost', { extend: 'Ext.data.Model', proxy: { type: 'ajax', url: 'AdvSearch.php', reader: { type: 'json', root: 'Arr', totalProperty: 'totalCount' } }, fields: [ { name: 'name'}, { name: 'type_and_cargo'} ] }); Ext.create('Ext.data.Store', { pageSize: 10, autoLoad: false, model: 'AdvSearchPost', storeId: 'AdvSearchPost' });

  • Loading non-RJS javascript via ajax in Rails

    - by David Smith
    I've written a rails module that generates some javascript for a google map. As the user makes changes on the webpage, I use observe_field to call back to the server to regenerate the map's javascript (without updating the whole page). I'm having trouble finding a good way to insert the new javascript into the page. I've tried <div id='my_div_1'>div1</div> <%= update_page_tag do |page| page.replace_html 'my_div_1', "<script>alert('hi');</script>" end %> but it seems that replace_html only works for non-script html. It chokes when the content includes the closing < /script tag. Additional information...here is a page that I think is the root of the problem. http://www.wwco.com/~wls/blog/2007/04/25/using-script-in-a-javascript-literal/

  • Ria Services loading foreign keys with Linq-to-SQL

    - by Stephan
    I have a database that consists of 5 tables : Course, Category, Location, CourseCategories, and CourseLocations. The last 2 tables just contain the two foreign keys. A Course has many-to-many relationships with both category and location. I am trying to load the data into a Silverlight app using Ria Services. My DB model is Linq-to-SQL. I have tried adding the [Include] attribute to the metadata classes and I have added the DataLoadOptions so it should load the all tables when you ask for a Course. However on the client side I am never getting back any entries in the CourseCategories and CourseLocations properties. What else needs to be done to get the foreign key relationships to exist across the serialization.

    Happy new year everybody! Basically, what I try to do is to save a subtitle to an annotation when the application terminates.

  • Dispose a Web Service Proxy class?

    - by Matt
    When you create and use a Web Service proxy class in the ASP.Net framework, the class ultimately inherits from Component, which implements IDisposable. I have never seen one example online where people dispose of a web proxy class, but was wondering if it really needs to be done. When I call only one method, I normally wrap it in a using statement, but if I have a need to call it several times throughout the page, I might end up using the same instance, and just wondered what the ramifications are of not disposing it.

  • executing a class in remote jvm

    - by redzedi
    Hi All, I have a small test class that i want to run on a particular jvm that's already up and running (basically it's an web application running on Tomcat) . The reason i want to do this is i want to execute a small test class (with the main method and all) within that jvm so that i get the same environment (loaded and initialized classes) for my test class. Is it possible to indicate that ,say through a jvm parameter, that it should not initialize a new vm to execute my class but instead go and execute on the remote vm and show me the result here, on my console. So the local jvm acts as a kind of thin proxy ? I am not aware in case there are some tools that should make this possible ... also heard somewhere that java 6 jvm comes with an option like this , is that true ?? Please help me. Thanks,

  • Using member variables inherited from a templated base class (C++)

    - by Aaron Becker
    I'm trying to use member variables of a templated base class in a derived class, as in this example: template <class dtype> struct A { int x; }; template <class dtype> struct B : public A<dtype> { void test() { int id1 = this->x; // always works int id2 = A<dtype>::x; // always works int id3 = B::x; // always works int id4 = x; // fails in gcc & clang, works in icc and xlc } }; gcc and clang are both very picky about using this variable, and require either an explicit scope or the explicit use of "this". With some other compilers (xlc and icc), things work as I would expect. Is this a case of xlc and icc allowing code that's not standard, or a bug in gcc and clang?

  • Incompatible classes when loading SWF

    - by Bart van Heukelom
    I have two ActionScript 3 projects, game(.swf) and minigame(.swf). At runtime the main game loads the minigame via Loader. I also have a shared library (SWC) of event classes, included by both, which minigame will need to dispatch and game will need to listen to. First: Is this possible this way? Second: What will happen if I compile the minigame, then change the event classes so they're incompatible, then compile the main game. Will Flash crash when trying to load the minigame SWF? (I hope so) Third: And what will happen if I change the event classes, but in a way that preserves interface-level compatibility?
