  • Why does C++ behave this way?

    - by eSKay
    #include<stdio.h> int b = 0; class A { public: int a;}; class B: public A { int c; int d; public: B(){ b++; a = b; printf("B:%d\n",b); } }; int main() { A* a = new B[10]; B* b = new B[10]; printf("\n%d", a->a); a++; printf("\n%d", a->a); // prints junk value printf("\n\n%d", b->a); b++; printf("\n%d", b->a); return 0; } The second printf prints a junk value. It should figure that it is pointing to an object of type B and increment by the sizof(B). Why does that not happen?

  • Is there a Python module for handling Python object addresses?

    - by cool-RR
    (When I say "object address", I mean the string that you type in Python to access an object. For example 'life.State.step'. Most of the time, all the objects before the last dot will be packages/modules, but in some cases they can be classes or other objects.) In my Python project I often have the need to play around with object addresses. Some tasks that I have to do: Given an object, get its address. Given an address, get the object, importing any needed modules on the way. Shorten an object's address by getting rid of redundant intermediate modules. (For example, 'life.life.State.step' may be the official address of an object, but if 'life.State.step' points at the same object, I'd want to use it instead because it's shorter.) Shorten an object's address by "rooting" a specified module. (For example, 'garlicsim_lib.simpacks.prisoner.prisoner.State.step' may be the official address of an object, but I assume that the user knows where the prisoner package is, so I'd want to use 'prisoner.prisoner.State.step' as the address.) Is there a module/framework that handles things like that? I wrote a few utility modules to do these things, but if someone has already written a more mature module that does this, I'd prefer to use that. One note: Please, don't try to show me a quick implementation of these things. It's more complicated than it seems, there are plenty of gotchas, and any quick-n-dirty code will probably fail for many important cases. These kind of tasks call for battle-tested code. UPDATE: When I say "object", I mostly mean classes, modules, functions, methods, stuff like these. Sorry for not making this clear before.

  • Magento - createBlock() in controller, can I access this in layout.xml?

    - by pspahn
    I have an index controller with a view action that does the following: echo $this->getLayout() ->createBlock('core/template','builder') ->setTemplate('pages/builder/view.phtml') ->setHeaderText($extra->getHeaderText()) ->setFooterText($extra->getFooterText()) ->setProducts($collection) ->toHtml(); Based on this, I am trying to perform layout updates in builder.xml (which is being set in the module's config.xml). However, I am not sure if you can target blocks instantiated in this manner. Based on the above block creation, am I able to perform the following: <layout version="0.1.0"> <builder_index_view> <!-- shouldn't this reference the createBlock() name argument? --> <reference name="builder"> <block type="page/html_header" name="builder.header" as="builder.header" template="pages/builder/header.phtml"/> </reference> </builder_index_view> </layout>

  • Silverlight Grid Layout is pain

    - by brainbox
     I think one of the biggest mistake of Silverlight and WPF is its Grid layout.Imagine you have a data form with 2 columns and 5 rows. You need to place new row after the first one. As a result you need to rewrite Grid.Rows and Grid.Columns in all rows belows. But the worst thing of such approach is that it is static. So you need predefine all your rows and columns. As a result creating of simple dynamic datagrid or dataform become impossible... So the question if why best practices of HTML and Adobe Flex were dropped????If anybody have tried to port Flex Grid layout to silverlight please mail me or drop a comment.

    I'm having trouble with a multi-layout option on a wordpress theme sight http://sight.wpshower.com/ the traffic have the option of a grid or a list layout at the click of a button. at present the list layout is default. I am interested in making the grid layout default . this is some of the php, i tried simply swapping the word grid for list but although this does work to an extent , if done on the loop.php page it removes the a:hover functions on the post boxes in the grid format. also if done on the index.php it switches buttons on the main index page. any ideas?? loop.php <div id="loop" class="<?php if ($_COOKIE['mode'] == 'grid') echo 'grid'; else echo 'list'; ?> clear"> <?php while ( have_posts() ) : the_post(); ?> <div <?php post_class('post clear'); ?> id="post_<?php the_ID(); ?>"> <?php if ( has_post_thumbnail() ) :?> <a href="<?php the_permalink() ?>" class="thumb"><?php the_post_thumbnail('thumbnail', array( 'alt' => trim(strip_tags( $post->post_title )), 'title' => trim(strip_tags( $post->post_title )), )); ?></a> <?php endif; ?> <div class="post-category"><?php the_category(' / '); ?></div> <h2><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2> <!-- <div class="post-meta">by <span class="post-author"><a href="<?php echo get_author_posts_url(get_the_author_meta('ID')); ?>" title="Posts by <?php the_author(); ?>"><?php the_author(); ?></a></span> on <span class="post-date"><?php the_time(__('M j, Y')) ?></span> <em>&bull; </em><?php comments_popup_link(__('No Comments'), __('1 Comment'), __('% Comments'), '', __('Comments Closed')); ?> <?php edit_post_link( __( 'Edit entry'), '<em>&bull; </em>'); ?> </div> --> <?php edit_post_link( __( 'Edit entry'), '<em>&bull; </em>'); ?> <div class="post-content"><?php if (function_exists('smart_excerpt')) smart_excerpt(get_the_excerpt(), 55); ?></div> </div> <?php endwhile; ?> </div> <?php endif; ?> index.php <?php get_header(); ?> <div class="content-title"> Projects <a href="javascript: void(0);" id="mode"<?php if ($_COOKIE['mode'] == 'grid') echo ' class="flip"'; ?>></a> </div> <?php query_posts(array( 'post__not_in' => $exl_posts, 'paged' => $paged, ) ); ?> <?php get_template_part('loop'); ?> <?php wp_reset_query(); ?> <?php get_template_part('pagination'); ?> <?php get_footer(); ?>

  • PHP city-sim castle layout

    - by Gert
    I am currently contemplating the layout system for my php based game but i've run into a couple of worries. So my idea is a 9X9 grid where the center 3X3 are inner castle. The inner castle will be 6X6 if you enter it(click on it). and with the option to expand the inner castle converting one of the 9X9 tiles to a 4X4 inner castle tile. So here is my question: What is the best way to tackle this type of layout? my original idea was a 18X18 grid and saving it in the db as (idCastle, Y, X) where X is a string of 18 numbers long telling me if the tile is an inner/outer tile or a inner/outer building. but i am not really fond of this idea and would like to hear some other ideas on how to tackle this. Thanks in Advance, Gert

  • Splitting Logic, Data, Layout and "Hacks"

    - by fjdumont
    Sure, we all heard of programming patterns such as MVVM, MVC and such. But that isn't really what I'm looking into as Layout, Data and Logic is already pretty much split up (XML-Layout markup, Database, insert your language of choice here). The platform I am developing for is hard to maintain over the updated versions and older OSes. The project significantly grew up over the last few months and dealing with different platform versions really is a pain. For example simply disabling an user interface control for all existing versions took me around 40 lines of code in the logic layer, wrangling around with invocation, delegation, singletons that provide UI handling and so on. Is there a clean way to keep track of those "hacks" by maybe excluding it into separate classes or even packages? Should I overwrite existing framework code in order to handle my requirements correctly? If so, does that concept have a name?

  • Object of type "X" cannot be converted to object of type "X"

    - by Benjol
    (Can't believe this hasn't already been asked, but I can't find a dup) In Visual Studio with lots of projects, when I first open the solution, I sometimes get the warning Object of type "X" cannot be converted to object of type "X". Generally rebuilding seems to make it go away, but does anyone know what this is caused by, and how to avoid it? UPDATE I read somewhere that deleting all your resx files and rebuilding can help. I unthinkingly tried this. Not a good idea...

  • C++ include statement required if defining a map in a headerfile.

    - by Justin
    I was doing a project for computer course on programming concepts. This project was to be completed in C++ using Object Oriented designs we learned throughout the course. Anyhow, I have two files symboltable.h and symboltable.cpp. I want to use a map as the data structure so I define it in the private section of the header file. I #include <map> in the cpp file before I #include "symboltable.h". I get several errors from the compiler (MS VS 2008 Pro) when I go to debug/run the program the first of which is: Error 1 error C2146: syntax error : missing ';' before identifier 'table' c:\users\jsmith\documents\visual studio 2008\projects\project2\project2\symboltable.h 22 Project2 To fix this I had to #include <map> in the header file, which to me seems strange. Here are the relevant code files: // symboltable.h #include <map> class SymbolTable { public: SymbolTable() {} void insert(string variable, double value); double lookUp(string variable); void init(); // Added as part of the spec given in the conference area. private: map<string, double> table; // Our container for variables and their values. }; and // symboltable.cpp #include <map> #include <string> #include <iostream> using namespace std; #include "symboltable.h" void SymbolTable::insert(string variable, double value) { table[variable] = value; // Creates a new map entry, if variable name already exist it overwrites last value. } double SymbolTable::lookUp(string variable) { if(table.find(variable) == table.end()) // Search for the variable, find() returns a position, if thats the end then we didnt find it. throw exception("Error: Uninitialized variable"); else return table[variable]; } void SymbolTable::init() { table.clear(); // Clears the map, removes all elements. }

  • Object oriented design suggestion

    - by pocoa
    Here is my code: class Soldier { public: Soldier(const string &name, const Gun &gun); string getName(); private: Gun gun; string name; }; class Gun { public: void fire(); void load(int bullets); int getBullets(); private: int bullets; } I need to call all the member functiosn of Gun over a Soldier object. Something like: soldier.gun.fire(); or soldier.getGun().load(15); So which one is a better design? Hiding the gun object as a private member and access it with getGun() function. Or making it a public member? Or I can encapsulate all these functions would make the implementation harder: soldier.loadGun(15); // calls Gun.load() soldier.fire(); // calls Gun.fire() So which one do you think is the best?
