vb.net arrays resize elements
Lets say I want to create an array with 20 elements all set to a default value (let’s say, 0)But later, during runtime, I might want to resize the array. I might make it larger, to support 30 elements. The 10 new elements will have the default value of 0.Or I might want to make my array smaller, to just 5. So I delete the complete the existence of the last 15 elements of the array.Thanks.

c++ pointers set elements stdvector
In the below program a string is added to an empty store. Then the address of this store element is stored in the pointer ‘s1’. Then another string is added and this somehow causes the pointer to the original element to fail.#include <iostream> #include <string> #include <vector>class store2 {public:void add(std::string s) {words.push_back(s); last_added2 = &words.at(words.size() – 1);}std::string* last_added() {return last_added2;}private:std::string* last_added2;std::vect

jquery input selectors elements
I have a form with dynamically created form elements.I need to get the value of each element, and send an ajax request to make sure the data is ok (the easy part). I can get each elements value easy enough, but the problem comes in with radio buttons. For example:<input type = ‘radio’ class = ‘form_element’ value = ‘1’> <input type = ‘radio’ class = ‘form_element’ value = ‘1’> <input type = ‘radio’ class = ‘form_element’ value = ‘1’>if i do something like…$(‘.form_element’).e

javascript arrays elements extra
In PHP, if you do this$var = array(); $var[5000] = 1; echo count($var);It prints 1. In JS it makes the “missing” elements. <script type=”text/javascript”>var fred = [];fred[10] = 1;alert(fred.length); </script>Alerts “11”.Can I prevent this? Is it good for anything? I’m a PHP coder trying to adapt to Javascript.EDIT:I’m working on an app that uses Google Maps v2 and markerManager. The code has been working for ages, but a problem has suddenly arisen in Chrome (17.0.963.56 m) where m

design-patterns dom backbone.js reference elements
I’m currently building a large backbone app, and here is my question. How to cope with DOM elements refernces the best way? Now I simply find all elements which will be accessed in a future (forms and things like that) in my view’s initialize function, and bind them to the view itself. This way I don’t have to search for these elements every time I need to interact with them. But number of this references is growing quite quickly actually. Is it good approach or can I do better?

I’m sure it’s something obvious about root level elements …Many thanks in advance, Gav
