  • convert int into string with certain length of char

    - by Tommy
    If the title wasn't clear, ill try to explain it well here. I have a bunch of integers, ranging from 1 to 999, and i need to convert these into strings, but when i do that, i need them to be 3 characters long. so for instance, if i had: int i1 = 45; then when i turned that into a string, i'd need this: "045" or similarly, if i had an int of 8 then that would have to turn into "008", and if anything had 3 places, such as 143, then it would just be outputted as 143. is this easily possible? Thanks for responses in advance. :)

  • Passing arguments and conditions to model in codeigniter

    - by stormdrain
    I'm adding some models to a project, and was wondering if there is a "best practice" kind of approach to creating models: Does it make sense to create a function for each specific query? I was starting to do this, then had the idea of creating a generic function that I could pass parameters to. e.g: Instead of function getClients(){ return $this->db->query('SELECT client_id,last FROM Names ORDER BY id DESC'); } function getClientNames($clid){ return $this->db->query('SELECT * FROM Names WHERE client_id = '.$clid); } function getClientName($nameID){ return $this->db->query('SELECT * FROM Names WHERE id ='.$nameID); } } Something like function getNameData($args,$cond){ if($cond==''){ $q=$this->db->query('SELECT '.$args.' FROM Names'); return $q; }else{ $q=$this->db->query('SELECT '.$args.' FROM Names WHERE '.$cond); return $q; } } where I can pass the fields and conditions (if applicable) to the model. Is there a reason the latter example would be a bad idea? Thanks!

  • Pass Arguments to Included Module in Ruby?

    - by viatropos
    I'm hoping to implement something like all of the great plugins out there for ruby, so that you can do this: acts_as_commentable has_attached_file :avatar But I have one constraint: That helper method can only include a module; it can't define any variables or methods. The reason for this is because, I want the options hash to define something like type, and that could be converted into one of say 20 different 'workhorse' modules, all of which I could sum up in a line like this: def dynamic_method(options = {}) include ("My::Helpers::#{options[:type].to_s.camelize}").constantize(options) end Then those 'workhorses' would handle the options, doing things like: has_many "#{options[:something]}" Here's what the structure looks like, and I'm wondering if you know the missing piece in the puzzle: # 1 - The workhorse, encapsuling all dynamic variables module My::Module def self.included(base) base.extend ClassMethods base.class_eval do include InstanceMethods end end module InstanceMethods self.instance_eval %Q? def #{options[:my_method]} "world!" end ? end module ClassMethods end end # 2 - all this does is define that helper method module HelperModule def self.included(base) base.extend(ClassMethods) end module ClassMethods def dynamic_method(options = {}) # don't know how to get options through! include My::Module(options) end end end # 3 - send it to active_record ActiveRecord::Base.send(:include, HelperModule) # 4 - what it looks like class TestClass < ActiveRecord::Base dynamic_method :my_method => "hello" end puts TestClass.new.hello #=> "world!" That %Q? I'm not totally sure how to use, but I'm basically just wanting to somehow be able to pass the options hash from that helper method into the workhorse module. Is that possible? That way, the workhorse module could define all sorts of functionality, but I could name the variables whatever I wanted at runtime.

  • Setting Environment Variable for Tomcat 6 Servlet

    - by amaevis
    I'm using Ubuntu's default installation of Tomcat 6. I'm deploying a ROOT.war, and trying to set an environment variable specific to it, i.e. accessible from System.getenv() in the Servlet.init(config). According to the docs (http://tomcat.apache.org/tomcat-6.0-doc/config/context.html), I can specify this in a Context element in conf/Catalina/localhost/ROOT.xml. I've created that with these contents: <Context> <Environment name="FOO" value="bar" type="java.lang.String" override="false"/> </Context> And I've deployed the webapp as usual, i.e. to webapps/ROOT.war. Server.getenv("FOO") in the Servlet.init(config) still returns null. What am I missing?

  • How to free static member variable in C++?

    - by user299831
    Can anybody explain how to free memory of a static member Variable? In my understanding it can only be freed if all the instances of the class are destroyed. I am a little bit helpless at this point... Some Code to explain it: class ball { private: static SDL_Surface *ball_image; }; //FIXME: how to free static Variable? SDL_Surface* ball::ball_image = SDL_LoadBMP("ball.bmp");

  • Given an array of arguments, how do I send those arguments to a particular function in Ruby?

    - by Steven Xu
    Forgive the beginner question, but say I have an array: a = [1,2,3] And a function somewhere; let's say it's an instance function: class Ilike def turtles(*args) puts args.inspect end end How do I invoke Ilike.turtles with a as if I were calling (Ilike.new).turtles(1,2,3). I'm familiar with send, but this doesn't seem to translate an array into an argument list. A parallel of what I'm looking for is the Javascript apply, which is equivalent to call but converts the array into an argument list.

  • Troubles with a PHP session variable after form submission

    - by Psyche
    Hello, I'm setting a PHP session variable with a success message for a HTML form that I'm submitting. If there are no form errors, I redirect to the same page (using header()) and display the message from the session variable. Everything is fine until here, but if I access that page again after submission, the message is still there. Is it possible to make it appear only when I redirect after a successful submit? Thank you.

  • Determine an object's class returned by a factory method (Error: function does not take 1 arguments

    - by tzippy
    I have a factorymethod that either returns an object of baseclass or one that is of derivedclass (a derived class of baseclass). The derived class has a method virtual void foo(int x) that takes one argument. baseclass however has virtual void foo() without an argument. In my code, a factory method returns a pointer of type bar that definetly points to an object of class derivedclass. However since this is only known at runtime I get a compiler error saying that foo() does not take an argument. Can I cast this pointer to a pointer of type derivedclass? std::auto_ptr<baseclass> bar = classfactory::CreateBar(); //returns object of class derivedclass bar->foo(5); class baseclass { public: virtual void foo(); } class derivedclass : public baseclass { public: virtual void foo(int x); }

  • Putting a variable name = value format in Ruby

    - by Calm Storm
    Hi, I would like to add some debugs for my simple ruby functions and I wrote a function as below, def debug(&block) varname = block.call.to_s puts "#{varname} = #{eval(varname,block)}" end debug {:x} #prints x = 5 debug {:y} #prints y = 5 I understand that eval is evil. So I have two questions. Is there any way to write that debug method without using eval? If NO is there a preferred way to do this? Is there any way to pass a list of arguments to this method? I would ideally prefer debug {:x, :y. :anynumOfvariables}. I could not quite figure out how to factor that into the debug method (i.e, to take a list of arguments)

  • typedef fixed length array

    - by Rajorshi
    Hi, I have to define a 24-bit data type.I am using char[3] to represent the type. Can I typedef char[3] to type24? I tried it in a code sample. I put typedef char[3] type42; in my header file. The compiler did not complain about it. But when I defined a function void foo(type24 val) {} in my C file, it did complain. I would like to be able to define functions like type24_to_int32(type24 val) instead of type24_to_int32(char value[3]).
