• different for lusses java

  - by Ayrton

  Hi I'm having some difficulties with the following problem: I'm making a little game where you're at a specific spot and each spot has each some possible directions. The available directions are N(ord),E(ast),S,W . I use the function getPosDirections to get the possible directions of that spot. The function returns the directions into an ArrayList e.g. for spot J3: [E,W] Now the game goes like this: 2 dices will be rolled so you get a number between 2 and 12, this number represents the number of steps you can make. What I want is an ArrayList of all the possible routes e.g.: I throw 3 and I'm currently at spot J3: [[E,N,E],[E,N,S],[E,S,E],[E,S,S],[W,N,E],[W,N,S],[W,S,E],[W,S,S]] How would obtain the last mentioned Array(list) Thanks in advance

• Form Arrays support across browsers

  - by Stomped

  I'm not even sure if form arrays is the proper term, but it looks a bit like this: <input name='element[]' type='text' /> <input name='element[]' type='text' /> Which is then retrieved in PHP as an array stored in $_POST['element'] -- in this case with 2 values. I've tested it in the browsers I have available to me, but I've never seen this before and I'm wondering is this supported pretty much in all browsers? Or is this something very old that I've just not run into? Thanks!

• Sending images using Http Post

  - by primal

  I want to send an image from the android client to the Django server using Http Post. The image is chosen from the gallery. At present, I am using list value name Pairs to send the necessary data to the server and receiving responses from Django in JSON. Can the same approach be used for images (with urls for images embedded in JSON responses)? Also which of, accesssing images remotely without downloading them from the server or downloading and storing them in a Bitmap array and using them locally is a better method? The images are few in number (<10) and small in size (50*50 dip). Any tutorial to tackle these problems would be much appreciated.

• Polymorphic behavior not being implemented

  - by Garrett A. Hughes

  The last two lines of this code illustrate the problem: the compiler works when I use the reference to the object, but not when I assign the reference to an array element. The rest of the code is in the same package in separate files. BioStudent and ChemStudent are separate classes, as well as Student. package pkgPoly; public class Poly { public static void main(String[] arg) { Student[] stud = new Student[3]; // create a biology student BioStudent s1 = new BioStudent("Tom"); // create a chemistry student ChemStudent s2 = new ChemStudent("Dick"); // fill the student body with studs stud[0] = s0; stud[1] = s1; // compiler complains that it can't find symbol getMajor on next line System.out.println("major: " + stud[0].getMajor() ); // doesn't compile; System.out.println("major: " + s0.getMajor() ); // works: compiles and runs correctly } }

• need a code snippet to find all *.html under a folder in nodejs

  - by Nicolas S.Xu

  I'd like to find all *.html files in src folder and all its sub folders using nodejs. What is the best way to do it? var folder = '/project1/src'; var extension = 'html'; var cb = function(err, results) { // results is an array of the files with path relative to the folder console.log(results); } // This function is what I am looking for. It has to recursively traverse all sub folders. findFiles(folder, extension, cb); I think a lot developers should have great and tested solution and it is better to use it than writing one myself.

• Android ListView Item Visibility

  - by user1478754

  I'm trying to create a screen that displays multiples items. For this, I've created a listview but I'm not sure how to approach how to add/remove items from it. Since I'm using custom listview items, I've created my own listadapter but now I need a way to add items on a button click. Is there a way to create listview that can take an indefinite amount of items (instead of passing it in an fixed length array of View objects)? Also what's the best way to remove items from listviews? setVisibility?

• returning values from function or method multiple times by only calling the class once

  - by Sokhrat Sikar

  I have a members.php file that shows my websites members. I echo members name by using foreach method. A method of Members class returns an array, then I use foreach loop in the members.php file to echo the members. I am trying to aovid writing php code in my members.php file. Is there a way to avoid using foreach inside members.php file? For example, is it possible to return value from a method couple of times? (by only calling the object once). Just like how we normally call the functions? This question doesn't make sense, but I am just trying to see if there is a away around this issue?

• what is the underlying data structure of a set c++?

  - by zebraman

  I would like to know how a set is implemented in C++. If I were to implement my own set container without using the STL provided container, what would be the best way to go about this task? I understand STL sets are based on the abstract data structure of a binary search tree. So what is the underlying data structure? An array? Also, how does insert() work for a set? How does the set check whether an element already exists in it? I read on wikipedia that another way to implement a set is with a hash table. How would this work?

  - by JasonS

  I have solved this problem, I just need to know what to do. I get the above error because I just realised that the class is being run as class::function($values) instead of class-function($values). Does anyone know how to convert this function to instantiate the class then run the function with values? private function _load($values=null) { define('LOADED_CONTROLLER', $this->controller); define('LOADED_FUNCTION', $this->function); $function = $this->function; $controller = new $this->controller; ($values == null) ? $controller->$function() : call_user_func_array(array($this->controller, $function), $values); }

• Can I extends a sub class of Proxy class?

  - by KCBérenger

  I want to create a complete (and real) 2-dimensional array. In order to use a maximum of Adobe code, I want to use ListCollectionView which can manage sort and filters. But to use a second dimension, I need to override getProperty method, like following code. package { import flash.utils.flash_proxy; import mx.collections.ListCollectionView; public class SubClass extends ListCollectionView /* extends Proxy */ { override flash_proxy function getProperty(name : *) : * { ... } override flash_proxy function setProperty(name : *, value : *) : void { ... } } } This code doesn't work. Flash Builder 4 said to me: 1004 Namespace was not found or is not a compile-time constant. If anyone has a solution or a clue...

• Can I use MFC objects in STL containers?

  - by Jesse Stimpson

  The following code doesn't compile for me in MSVC2005: std::vector<CMenu> vec(10); CMenu is an MFC menu object (such as a context menu). Through some testing I learned that CMenu does not have a public copy constructor. To do what I wanted to do, I needed to use a dynamic array. CMenu* menus = new CMenu[10]; // ... delete [] menus; Of course, now I've lost all the benefits of using an STL container. Do I have any other options?

• PHP Extract Values From One String Based on a Pattern Defined in Another

  - by ironkeith

  I have two strings: $first = '/this/is/a/string'; $second = '/this/:param1/a/:param2'; And I'm trying to get this: $params = array('param1' => 'is', 'param2' => 'string'); But getting from point a to b is proving more than my tired brain can handle at the moment. Anything starting with a ':' in the second string defines a variable name/position. There can be any number of variables in $second which need to be extracted from $first. Segments are separated by a '/'. Thanks.
