  • Class with proprties that haven't been set

    - by koumides
    Hello there, I am creating a class in C# which eventually will be part of a library that other uses can use. A user of this class has to set some properties and then use a public method to retrieve the results. What shall I do when a user calls the method without setting all the properties? Throw exception and expect the user to catch it? Thanks

  • Problem displaying contents of a class in Java

    - by LuckySlevin
    My problem is i have a class and in it there is a list of elements of another class. public class Branch { private ArrayList<Player> players = new ArrayList<Player>(); String brName; public Branch() {} public void setBr(String brName){this.brName = brName;} public String getBr(){return brName;} public ArrayList<Player> getPlayers() { return players; } public void setPlayers(ArrayList<Player> players) { this.players =new ArrayList<Player>(players); } } public class Player { private String name; private String pos; private Integer salary; private Integer number; public Player(String name, String pos, Integer salary, Integer number) { this.name = name; this.pos = pos; this.salary = salary; this.number = number; } public Player(){} public String getName() { return name; } public String getPos() { return pos; } public Integer getSalary() { return salary; } public Integer getNumber() { return number; } public void setName(String name) { this.name = name; } public void setPos(String pos) { this.pos = pos; } public void setSalary(Integer salary) { this.salary = salary; } public void setNumber(Integer number) { this.number = number; } } My problem is to print the players of a Branch with their name,pos,salary,number. For this i tried this simply : String p1,p2; int a1,a2; p1 = input.readLine(); p2 = input.readLine(); a1 = Integer.parseInt(input.readLine()); a2 = Integer.parseInt(input.readLine()); players[0].setName(p1); players[0].setPos(p2); players[0].setSalary(a1); players[0].setNumber(a2); ptmp.add(players[0]); myBranch[0].setPlayers(ptmp); System.out.println(myBranch[0].brName + " " + myBranch[0].getPlayers()); I wrote this just to try how to display. I created an array of Players, and Branches so they already defined. The problem is getPlayers() doesn't give me any result. What is the way to do this?

  • Does binding temporary to a reference require a copy constructor in C++?

    - by vitaut
    Consider the following code: class A { A(const A&); public: A() {} }; int main() { const A &a = A(); } This code compiles fine with GCC, but fails to compile with Visual C++ with the following error: test.cc(8) : error C2248: 'A::A' : cannot access private member declared in class 'A' test.cc(2) : see declaration of 'A::A' test.cc(1) : see declaration of 'A' So is it necessary to have a copy constructor accessible when binding a temporary to a reference?

  • PHP coding - A class for each view or one class to rule them all?

    - by Kyle
    I am starting my first "programming" project in PHP making some sort of web application that give the linux program, Motion, a decent web interface. Anyways, I was curious as to how when real applications are programmed, do y'all go for a class for each view or one single class for the application altogether? I know this is more of a preference thing, I was just curious as to how it happens in real software.

  • Winform/Program and how to write class 1, class 2, class 3, class 4 in array to linklabels?!!?

    - by JB
    So my program works like this: using winforms, user enters ID number, using an array, based on the right id number, that student information and class schedule outputs in a message box! My question is how to take the 4 classes in the message box/array and write them to the linklabel text in form 2???? My Getschedule class contains the array and is listed below: namespace Eagle_Eye_Class_Finder { public class GetSchedule { IDnumber[] IDnumbers = new IDnumber[3]; public string GetDataFromNumber(string ID) { foreach (IDnumber IDCandidateMatch in IDnumbers) { if (IDCandidateMatch.ID == ID) { StringBuilder myData = new StringBuilder(); myData.AppendLine(IDCandidateMatch.Name); myData.AppendLine(": "); myData.AppendLine(IDCandidateMatch.ID); myData.AppendLine(IDCandidateMatch.year); myData.AppendLine(IDCandidateMatch.class1); myData.AppendLine(IDCandidateMatch.class2); myData.AppendLine(IDCandidateMatch.class3); myData.AppendLine(IDCandidateMatch.class4); //return myData; return myData.ToString(); } } return ""; } public GetSchedule() { IDnumbers[0] = new IDnumber() { Name = "Joshua Banks", ID = "900456317", year = "Senior", class1 = "TEET 4090", class2 = "TEET 3020", class3 = "TEET 3090", class4 = "TEET 4290" };

} public class IDnumber { public string Name { get; set; } public string ID { get; set; } public string year { get; set; } public string class1 { get; set; } public string class2 { get; set; } public string class3 { get; set; } public string class4 { get; set; } public static void ProcessNumber(IDnumber myNum) { StringBuilder myData = new StringBuilder(); myData.AppendLine(myNum.Name); myData.AppendLine(": "); myData.AppendLine(myNum.ID);

  • Continuing JavaScript "classes" - enums within

    - by espais
    From a previous question, I have the following: So I have implemented a resource class, now I'd like to continue extending it and add all my constants and enums (or as far as JS will allow...). This is what I currently have: var resources = { // images player : new c_resource("res/player.png"), enemies : new c_resource("res/enemies.png"), tilemap : new c_resource("res/tilemap.png") }; And this is what I would like to continue to extend it to: var resources = { // images player : new c_resource("res/player.png"), enemies : new c_resource("res/enemies.png"), tilemap : new c_resource("res/tilemap.png"), // enums directions : {up:0, right:1, down:2, left:3}, speeds : {slow: 1, medium: 3, fast: 5} }; ... function enemies() { this.dir = resources.directions.down; // initialize to down } When I attempt to access resources.directions.up, my JS script goes down in a flaming pile of burning code. Are enums allowed in this context, and if not, how can I properly insert them to be used outside of a normal function? I have also tried defining them as global to a similar effect. edits: fixed the comma...that was just an error in transcribing it. When I run it in Firefox and watch the console, I get an error that says resources is undefined. The resources 'class' is defined at the top of my script, and function enemies() directly follows...so from what I understand it should still be in scope...

  • Is the Google Webmaster Tools verification temporary?

    - by Senseful
    When you add a site to Google Webmaster Tools, it asks you to verify it (e.g. via a <meta> tag). I verified a site a while ago, but when I logged in, I noticed that it isn't verified anymore. The history shows that it was verified 58 days ago, but then 30 days ago it tried and failed saying that "revierification failed". I'm not sure if this is a result of some setting I changed which required a reverification, or if Google Webmaster Tools periodically tries to verify the site. I was under the impression that the verification only happens once when you add the site, and then you can delete the <meta> tag. If this is not how it works, and it does reverify periodically, will it require a different <meta> tag value or can I keep the original one I used and never have to worry about it again?

  • Intermittent temporary GUI freeze in Ubuntu 11.10

    - by Oscar
    I've been using Ubuntu 11.10 for a month or so. In the last week it's started freezing randomly (every few hours or minutes). I can still move the mouse and switch to other terminals with ctrl+alt. I thought this was purely a gui issue as I could continue entering commands (mouse clicks and keys) which seem to be processed once the system resumes (generally 30 seconds to a few minutes). I'm using gnome and metacity. I can't identify anything in particular that triggers the freezes. Saving a file in LibreOffice causes the system to hang. I tried disabling most of the services I've installed (dropbox, autokey, etc.) but doesn't help. Switching to another terminal and running top, the CPU column is shared equally among all of my processes (i.e. non-root). I have no idea what that signifies. My PC is unusable in this state.

  • Temporary website redirect: 3xx or php/meta?

    - by Damien Pirsy
    Hi, I run a (small) news website which has also a forum in a subfolder of the root. I'm planning to give the site a facelift and a code restructuration, so I wanted to put some redirect on the home page that will point directly to forum's index (www.mysite.com -- www.mysite.com/forum) while I tinker with it. And that, given the little free time I have, will take no less than a couple of month. Being a news site I'm pretty sure that would affect it's overall ranking, but I need to do it, so: which is the best way to redirect? I pondered and read here and there about the different means, but I couldn't figure out which is worst for SEO. Do I use a 302 redirect or use "Location:newurl" in page headers using php? Or I just put a meta tag in the html page (or a javascript, what's better). Sorry but I'm not really into these things, I may have said something silly, I know... Thanks

  • Temporary dimming of desktop in 12.04

    - by deshmukh
    I am running Ubuntu 12.04 (almost default install regularly updated) Unity interface on ASUS X53U (AMD Brazos Dual Core C60 with 2GB RAM). On launching Thunderbird and Firefox, the application dims and the cursor changes to wait mode. In case of Thunderbird, this is most pronounced with the wait time of up to a minute. Memory status checked with free indicates around 500MB of free memory on such occasions. The OS is stable and I can switch to a different work-space, etc. What could this be? Is this something normal?

  • chrome download interrupted leaving ".crdownload" temporary file

    - by Tim
    I am using Google Chrome 15.0.874.121 in Ubuntu 10.10. It was fine until recently. Whenever download a file, it always reports "Interrupted", but it actually finishes the downloading, leaving an intermediate file with extension ".crdownload". If removed the extension, the file will be perfect. Note that downloading in Firefox works fine at the same time. So I wonder if it is a bug or how I can fix it? Thanks and regards!

  • JavaScript Class Patterns &ndash; In CoffeeScript

    - by Liam McLennan
    Recently I wrote about JavaScript class patterns, and in particular, my favourite class pattern that uses closure to provide encapsulation. A class to represent a person, with a name and an age, looks like this: var Person = (function() { // private variables go here var name,age; function constructor(n, a) { name = n; age = a; } constructor.prototype = { toString: function() { return name + " is " + age + " years old."; } }; return constructor; })(); var john = new Person("John Galt", 50); console.log(john.toString()); Today I have been experimenting with coding for node.js in CoffeeScript. One of the first things I wanted to do was to try and implement my class pattern in CoffeeScript and then see how it compared to CoffeeScript’s built-in class keyword. The above Person class, implemented in CoffeeScript, looks like this: # JavaScript style class using closure to provide private methods Person = (() -> [name,age] = [{},{}] constructor = (n, a) -> [name,age] = [n,a] null constructor.prototype = toString: () -> "name is #{name} age is #{age} years old" constructor )() I am satisfied with how this came out, but there are a few nasty bits. To declare the two private variables in javascript is as simple as var name,age; but in CoffeeScript I have to assign a value, hence [name,age] = [{},{}]. The other major issue occurred because of CoffeeScript’s implicit function returns. The last statement in any function is returned, so I had to add null to the end of the constructor to get it to work. The great thing about the technique just presented is that it provides encapsulation ie the name and age variables are not visible outside of the Person class. CoffeeScript classes do not provide encapsulation, but they do provide nicer syntax. The Person class using native CoffeeScript classes is: # CoffeeScript style class using the class keyword class CoffeePerson constructor: (@name, @age) -> toString: () -> "name is #{@name} age is #{@age} years old" felix = new CoffeePerson "Felix Hoenikker", 63 console.log felix.toString() So now I have a trade-off: nice syntax against encapsulation. I think I will experiment with both strategies in my project and see which works out better.

  • A Temporary Disagreement

    Last month, Phil Factor caused a furore amongst some MVPs with an article that dared to suggest that for reasonably small-scale strategic uses, and with a bit of due care and testing, table variables are a "good thing".

  • Extract all related class type aliasing and enum into one file or not

    - by Chen OT
    I have many models in my project, and some other classes just need the class declaration and pointer type aliasing. It does not need to know the class definition, so I don't want to include the model header file. I extract all the model's declaration into one file to let every classes reference one file. model_forward.h class Cat; typedef std::shared_ptr<Cat> CatPointerType; typedef std::shared_ptr<const Cat> CatConstPointerType; class Dog; typedef std::shared_ptr<Dog> DogPointerType; typedef std::shared_ptr<const Dog> DogConstPointerType; class Fish; typedef std::shared_ptr<Fish> FishPointerType; typedef std::shared_ptr<const Fish> FishConstPointerType; enum CatType{RED_CAT, YELLOW_CAT, GREEN_CAT, PURPLE_CAT} enum DogType{HATE_CAT_DOG, HUSKY, GOLDEN_RETRIEVER} enum FishType{SHARK, OCTOPUS, SALMON} Is it acceptable practice? Should I make every unit, which needs a class declaration, depends on one file? Does it cause high coupling? Or I should put these pointer type aliasing and enum definition inside the class back? cat.h class Cat { typedef std::shared_ptr<Cat> PointerType; typedef std::shared_ptr<const Cat> ConstPointerType; enum Type{RED_CAT, YELLOW_CAT, GREEN_CAT, PURPLE_CAT} ... }; dog.h class Dog { typedef std::shared_ptr<Dog> PointerType; typedef std::shared_ptr<const Dog> ConstPointerType; enum Type{HATE_CAT_DOG, HUSKY, GOLDEN_RETRIEVER} ... } fish.h class Fish { ... }; Any suggestion will be helpful.

  • Should package structure closely resemble class hierarchy?

    - by Panzercrisis
    Pretty simple question. Should package structure closely resemble class hierarchy? If so, how closely? Why or why not? For instance, let's say you've got class A and class B, plus class AFactory and class BFactory. You put class A and class B in the package com.something.elements, and you put AFactory and BFactory in com.something.elements.factories. AFactory and BFactory would be further down the hierarchy package-wise, but they'd be further up class-wise. Is this sort of thing a good idea or a bad idea?

  • Excel VBA: Passing a collection from a class to a module issue

    - by Martin
    Hello, I have been trying to return a collection from a property within a class to a routine in a normal module. The issue I am experiencing is that the collection is getting populated correctly within the property in the class (FetchAll) but when I pass the collection back to the module (Test) all the entries are populated with the last item in the list. This is the Test sub-routine in the standard module: Sub Test() Dim QueryType As New QueryType Dim Item Dim QueryTypes As Collection Set QueryTypes = QueryType.FetchAll For Each Item In QueryTypes Debug.Print Item.QueryTypeID, _ Left(Item.Description, 4) Next Item End Sub This is the FetchAll property in the QueryType class: Public Property Get FetchAll() As Collection Dim RS As Variant Dim Row As Long Dim QTypeList As Collection Set QTypeList = New Collection RS = .Run ' populates RS with a record set from a database (as an array), ' some code removed ' goes through the array and sets up objects for each entry For Row = LBound(RS, 2) To UBound(RS, 2) Dim QType As New QueryType With QType .QueryTypeID = RS(0, Row) .Description = RS(1, Row) .Priority = RS(2, Row) .QueryGroupID = RS(3, Row) .ActiveIND = RS(4, Row) End With ' adds new QType to collection QTypeList.Add Item:=QType, Key:=CStr(RS(0, Row)) Debug.Print QTypeList.Item(QTypeList.Count).QueryTypeID, _ Left(QTypeList.Item(QTypeList.Count).Description, 4) Next Row Set FetchAll = QTypeList End Property This is the output I get from the debug in FetchAll: 1 Numb 2 PBM 3 BPM 4 Bran 5 Claw 6 FA C 7 HNW 8 HNW 9 IFA 10 Manu 11 New 12 Non 13 Numb 14 Repo 15 Sell 16 Sms 17 SMS 18 SWPM This is the output I get from the debug in Test: 18 SWPM 18 SWPM 18 SWPM 18 SWPM 18 SWPM 18 SWPM 18 SWPM 18 SWPM 18 SWPM 18 SWPM 18 SWPM 18 SWPM 18 SWPM 18 SWPM 18 SWPM 18 SWPM 18 SWPM 18 SWPM Anyone got any ideas?

  • ActionScript - clicking and determining the sprite's class

    - by TheDarkIn1978
    i'd like to add all or most of my mouse events to stage, but in order to do that i need to be able to tell what is the type of the sprite being clicked. i've added two sprites to the display list, one of which is from a class called Square, the other from a class called Circle. var mySquare:Sprite = new Square(); var myCircle:Sprite = new Circle(); addChild(mySquare); addChild(myCircle); now when i click on these sprites, i'd like to know from which class they are from, or which type of sprite it is. //mousePoint returns mouse coordinates of the stage var myArray:Array = stage.getObjectsUnderPoint(mousePoint()); if (myArray[myArray.length - 1] is Sprite) ... so far i know how to do is determine if it IS a sprite display object, but since i'll only be working with sprites i need something more specific. rather than checking "is Sprite", is there a way i can check "is Square" or "is Circle"? if (myArray[myArray.length - 1] is Square)

  • Flex : providing data with a PHP Class

    - by Tristan
    Hello, i'm a very new user to flex (never use flex, nor flashbuilder, nor action script before), but i want to learn this langage because of the beautiful RIA and chart it can do. I watched the video on adobe : 1 hour to build your first program but i'm stuck : On the video it says that we have to provide a PHP class for accessing data and i used the example that flash builder gave (with zend framework and mysqli). I never used those ones and it makes a lot to learn if i count zen + mysqli. My question is : can i use a PHP class like this one ? What does flash builder except in return ? i hear that was automatic. example it may be wrong, i'm not very familiar with classes when acessing to database : <?php class DBConnection { protected $server = "localhost"; protected $username = "root"; protected $password = "root"; protected $dbname = "something"; protected $connection; function __construct() { $this->connection = mysql_connect($this->server, $this->username, $this->password); mysql_select_db($this->dbname,$this->connection); mysql_query("SET NAMES 'utf8'", $this->connection); } function query($query) { $result = mysql_query($query, $this->connection); if (!$result) { echo 'request error ' . mysql_error($this->connection); exit; } return $result; } function getAll() { $req = "select * from servers"; $result = query($req) return $result } function num_rows() { return mysql_num_rows($result); } function end() { mysql_close($this->connection); } } ?> Thank you,

  • Class design when working with dataset

    - by MC
    If you have to retrieve data from a database and bring this dataset to the client, and then allow the user to manipulate the data in various ways before updating the database again, what is a good class design for this if the data tables will not have a 1:1 relationship with the class objects? Here are some I came up with: Just manipulate the DataSet itself on the client and then send it back to the database as is. This will work though obviously the code will be very dirty and not well-structured. Same as #1, but wrap the dataset code around classes. What I mean is that you may have a class that takes a dataset or a datatable in its constructor, and then provides public methods and properties to simplify the code. Inside these methods and properties it will be reading or manipulating the dataset. To update the database afterwards will be easy because you already have the updated dataset. Get rid of the dataset entirely on the client, convert to objects, then convert back to a dataset when needing to update the database. Is there any good resources where I can find information on this?
