• penalty for "inlined" classes

  - by 2di

  Hi All Visual studio allow you to create "inlined" classes (if I am not mistaken with the name). So class header and implementation all in one file. H. file contain definitions and declarations of the class and functions, there is no .cpp file at all. So I was wondering if there is any penalty for doing it that way? any disadvantages ? Thanks a lot

• Catch requests to non-existent classes (not autoload)

  - by Spot

  Is there a manner in which to catch requests to a class which does not exist. I'm looking for something exactly like __call() and __static(), but for classes as opposed to methods in a class. I am not talking about autoloading. I need to be able to interrupt the request and reroute it. Ideas?

• Is there any online web application for daily activity logs [closed]

  - by user25

  I am looking for daily calendar-like apps, but ones that have some text editor attached for every day. All I want to do is that when I open that page, it should open the text editor for that day and I could enter some data of what I have accomplished, then save it. The next day I'd like it so when I open the application, then I can go to new page, but I have all of the previous day's data to have a look at what I have done. Something like Google calendar, but I need an associated text editor to paste some notes, stuff, etc. on a daily basis with logs.

• online backup plan for a home office with servers

  - by TiernanO

  So, i am in the process of tweaking my spending and i need to change my backup plan... I am currently using a mix of JungleDisk and ZManda ZCB to backup files on my MacBook Pro, Main Windows Server Wrokstation, a dedicated Windows Server in a datacenter, and various other machines and file sources. The problem is the cost: this month, it has cost me about $90 to backup a little over 500Gb... This amount of data will increese over time too, since i am backing up Photos (24Mb RAW images + 4-8MB JPEGs), Videos (various cameras shooting 720p and 1080p), Music, Movies, TV shows and Apps from iTunes (though with iTunes cloud, this might not need to be backed up again) and source code... I have looked at the likes of Mozy, CrashPlan+ and Pro, Backblaze and Carbonite, but each have their problems: Mozy seems overly expenvice per gig at 50C Crashplan wont sell to me since i am outside the US (they hide it on their site... hidden in the FAQ section!) Backblaze dont support Windows Server Carbonite business pricing is $600 up front for 500Gb of storage... Fro $229, they will not backup Windows Servers. So, other than those, Jungle Disk (at 15c per Gig) or ZManda (also at 15c per Gig) what other options are there? what are other people using?

• How to deal with static utility classes when designing for testability

  - by Benedikt

  We are trying to design our system to be testable and in most parts developed using TDD. Currently we are trying to solve the following problem: In various places it is necessary for us to use static helper methods like ImageIO and URLEncoder (both standard Java API) and various other libraries that consist mostly of static methods (like the Apache Commons libraries). But it is extremely difficult to test those methods that use such static helper classes. I have several ideas for solving this problem: Use a mock framework that can mock static classes (like PowerMock). This may be the simplest solution but somehow feels like giving up. Create instantiable wrapper classes around all those static utilities so they can be injected into the classes that use them. This sounds like a relatively clean solution but I fear we'll end up creating an awful lot of those wrapper classes. Extract every call to these static helper classes into a function that can be overridden and test a subclass of the class I actually want to test. But I keep thinking that this just has to be a problem that many people have to face when doing TDD - so there must already be solutions for this problem. What is the best strategy to keep classes that use these static helpers testable?

• Best way to go for simple online multi-player games?

  - by Mr_CryptoPrime

  I want to create a trivia game for my website. The graphic design does not have to be too fancy, probably no more advanced than a typical flash game. It needs to be secure because I want users to be able to play for real money. It also needs to run fast so users don't spend their time frustrated with game freezing. Compatibility, as with almost all online products, is key because of the large target market. I am most acquainted with Java programming, but I don't want to do it in Java if there is something much better. I am assuming I will have to utilize a variety of different languages in order for everything to come together. If someone could point out the main structure of everything so I could get a good start that would be great! 1) Language choice for simple secure online multiplayer games? 2) Perhaps use a database like MySQL, stored on a secure server for the trivia questions? 3) Free educational resources and even simpler projects to practice? Any ideas or suggestions would be helpful...Thanks!

• Classes as a compilation unit

  - by Yannbane

  If "compilation unit" is unclear, please refer to this. However, what I mean by it will be clear from the context. Edit: my language allows for multiple inheritance, unlike Java. I've started designing+developing my own programming language for educational, recreational, and potentially useful purposes. At first, I've decided to base it off Java. This implied that I would have all the code be written inside classes, and that code compiles to classes, which are loaded by the VM. However, I've excluded features such as interfaces and abstract classes, because I found no need for them. They seemed to be enforcing a paradigm, and I'd like my language not to do that. I wanted to keep the classes as the compilation unit though, because it seemed convenient to implement, familiar, and I just liked the idea. Then I noticed that I'm basically left with a glorified module system, where classes could be used either as "namespaces", providing constants and functions using the static directive, or as templates for objects that need to be instantiated ("actual" purpose of classes in other languages). Now I'm left wondering: what are the benefits of having classes as compilation units? (Also, any general commentary on my design would be much appreciated.)

• Python class design - Splitting up big classes into multiple ones to group functionality

  - by Ivo Wetzel

  OK I've got 2 really big classes 1k lines each that I currently have split up into multiple ones. They then get recombined using multiple inheritance. Now I'm wondering, if there is any cleaner/better more pythonic way of doing this. Completely factoring them out would result in endless amounts of self.otherself.do_something calls, which I don't think is the way it should be done. To make things clear here's what it currently looks like: from gui_events import GUIEvents # event handlers from gui_helpers import GUIHelpers # helper methods that don't directly modify the GUI # GUI.py class GUI(gtk.Window, GUIEvents, GUIHelpers): # general stuff here stuff here One problem that is result of this is Pylint complaining giving me trillions of "init not called" / "undefined attribute" / "attribute accessed before definition" warnings.

• How to import classes into other classes within the same file in Python

  - by Chris

  I have the file below and it is part of a django project called projectmanager, this file is projectmanager/projects/models.py . Whenever I use the python interpreter to import a Project just to test the functionality i get a name error for line 8 that FileRepo() cannot be found. How Can I import these classes correctly? Ideally what I am looking for is each Project to contain multiple FileRepos which each contain and unknown number of files. Thanks for any assistance in advance. #imports from django.db import models from django.contrib import admin #Project is responsible for ensuring that each project contains all of the folders and file storage #mechanisms a project needs, as well as a unique CCL# class Project(models.Model): ccl = models.CharField(max_length=30) Techpacks = FileRepo() COAS = FileRepo() Shippingdocs = FileRepo() POchemspecs = FileRepo() Internalpos = FileRepo() Finalreports = FileRepo() Batchrecords = FileRepo() RFPS = FileRepo() Businessdev = FileRepo() QA = FileRepo() Updates = FileRepo() def __unicode__(self): return self.ccl #ProjectFile is the file object used by each FileRepo component class ProjectFile(models.Model): file = models.FileField(uploadto='ProjectFiles') def __unicode__(self): return self.file #FileRepo is the model for the "folders" to be used in a Project class FileRepo(models.Model): typeOf = models.CharField(max_length=30) files = models.ManyToManyField(ProjectFile) def __unicode__(self): return self.typeOf

• Why does forward declaration not work with classes?

  - by eSKay

  int main() { B bb; //does not compile (neither does class B bb;) C cc; //does not compile struct t tt; //compiles class B {}; struct s { struct t * pt; }; //compiles struct t { struct s * ps; }; return 0; } class C {}; I just modified the example given here. Why is that the struct forward declarations work but not the class forward declarations? Does it have something to do with the namespaces - tag namespace and typedef namespace? I know that the structure definitions without typedefs go to tag namespace. Structures are just classes with all public members. So, I expect them to behave similarly.

• Problem using in GWT project classes from other project/source folders

  - by voipsecuritydigest.com

  My project contains 2 source folder, one is generic J2EE application another is smartCleintGWT, I want to use some already existing DTO classes from first source folder (src) Note that class used on client side and on server side of GWT project! When I do that I getting error [ERROR] Errors in 'file:/C:/..Projects/Admin/DMX/src_console/com/ho/nod/client/AdminRPC.java' [ERROR] Line 7: No source code is available for type com.dmx.synch.server.descriptors.DMXLicense; did you forget to inherit a required module? Source is available obviously; is there any way to import all that into GWT? PS In the future 2 source folder will be separated into 2 projects...I hope it wont be that complicated as well.

• Free downloadable products in Magento

  - by Aaron Newton

  Hello Magento boffins. I am using Magento to build an eBooks site. For the release, we plan to have a number of free downloadable books. We were hoping that it would be possible to use the normal Magento 'catalog' functionality to add categories with products underneath. However, since these are free downloadable products, it doesn't really make sense to send users through the checkout when they try to download. Does anyone know of a way to create a free downloadable product which bypasses the checkout altogether? I have noticed that there is a 'free sample' option for downloadable products, but I would prefer not to use this if I can as I plan to use this field for its intended purpose when I add paid products.

• Best Online Programming Degree? (Masters Level)

  - by Jason

  I am less then a year from graduating with my bachelors in web development, however I would like to continue on with a masters in programming. As far as I can tell, what I want is a masters in software engineering. Sadly my current college only offers more management oriented masters level degrees, and I want something that is programming, not business. Ultimately my goal is to teach online and work freelance on the side. Here's the problem - I am visually impaired, so I do not drive and I prefer to take my classes entirely online. I have heard enough to avoid university of phoenix... and I have heard some good about walden, regis, and penn state's online MSSE programs. I am wondering if anyone here knows of any other good ones, or ones I should avoid. I have heard mixed reviews of Colorado Tech.

• Can you select an element with two classes in jQuery

  - by Petras

  I have an element that has two classes but can't seem to select it with jQuery. Is it possible. Here's the code: <html> <head runat="server"> <script type="text/javascript" src="abc/scripts/jquery-1.4.2.min.js"></script> <script type="text/javascript"> $(document).ready(function() { alert($(".x.y").html()); //shows null, I want it to show "456" }); </script> </head> <body> <div class="x" class"y">456</div> </body> </html>

• C++ Template Classes Circular Dependency Problem

  - by TomWij

  We have two classes: template<typename T, typename Size, typename Stack, typename Sparse> class Matrix and template<typename T, typename Size> class Iterator Matrix should be able to return begin and end iterators and Iterator will keep a referrence to the Matrix to access the elements via it's interface. We don't want Iterator to depend on the internal storage of the Matrix to prevent coupling. How can we solve this cyclic dependency problem? (The internal Storage class has the same template parameters as the Matrix class and the same access procedures as the Matrix itself)

• Declare two classes from eachother.

  - by tumba25

  I'm writing a app in NetBeans. I have two classes MyApp_View and MyApp_Functions. The MyApp_View class starts like this public class MyApp_View extends FrameView { MyApp_Functions My_functions = new MyApp_Functions(); public MyApp_View(SingleFrameApplication app) { super(app); In MyApp_Functions I have MyApp_View my_view = new MyApp_View(null); I want to access the public variables in MyApp_View from MyApp_Functions and the public methods in functions from view, but have no success with this. Is this doable? And how?

• Beginner having a problem with classes

  - by David

  I'm working through O'Reilly's "Learning Python" and having a problem with classes. I think I understand the concept, but in practice have stumbled upon this problem. Fron page 88-89: >>> class Worker: def __innit__(self, name, pay): self.name=name self.pay=pay def lastName(self): return self.name.split()[-1] def giveRaise(self, percent): self.pay*=(1.0+percent) Then the book says "Calling the class like a function generates instances of a new type ...etc" and gives this example. bob = Worker('Bob Smith', 50000) This gives me this error: TypeError: this constructor takes no arguments. And then I start muttering profanities. So what am I doing wrong here? Thanks for the help.

• Java: Non-static nested classes and instance.super()

  - by Kiv

  I'm having a hard time wrapping my head around non-static nested classes in Java. Consider the following example, which prints "Inner" and then "Child". class Outer { class Inner { Inner() { System.out.println("Inner"); } } } public class Child extends Outer.Inner { Child(Outer o) { o.super(); System.out.println("Child"); } public static void main(String args[]) { new Child(new Outer()); } } I understand that instances of Inner always have to be associated with an Outer instance, and that that applies to Child too since it extends Inner. My question is what the o.super() syntax means - why does it call the Inner constructor? I've only seen a plain super(args) used to call the superclass constructor and super.method() to call the superclass version of an overridden method, but never something of the form instance.super().

• AS3 Memory management when instantiating extended classes

  - by araid

  I'm developing an AS3 application which has some memory leaks I can't find, so I'd like to ask some newbie questions about memory management. Imagine I have a class named BaseClass, and some classes that extend this one, such as ClassA, ClassB, etc. I declare a variable: myBaseClass:BaseClass = new ClassA(); After a while, I use it to instantiate a new object: myBaseClass = new ClassB(); some time after myBaseClass = new ClassC(); and the same thing keeps happening every x millis, triggered by a timer. Is there any memory problem here? Are the unused instances correctly deleted by the garbage collector? Thanks!

• Python New-style Classes and the Super Function

  - by sfjedi

  This is not the result I expect to see: class A(dict): def __init__(self, *args, **kwargs): self['args'] = args self['kwargs'] = kwargs class B(A): def __init__(self, *args, **kwargs): super(B, self).__init__(args, kwargs) print 'Instance A:', A('monkey', banana=True) #Instance A: {'args': ('monkey',), 'kwargs': {'banana': True}} print 'Instance B:', B('monkey', banana=True) #Instance B: {'args': (('monkey',), {'banana': True}), 'kwargs': {}} I'm just trying to get classes A and B to have consistent values set. I'm not sure why the kwargs are being inserted into the args, but I'm to presume I am either calling init() wrong from the subclass or I'm trying to do something that you just can't do. Any tips?

• sharepoint online quick launch

  - by Brian

  Hello, we are converting from sharepoint 2003 to sharepoint on line. I am having trouble reproducing a specific behavior in the online version. If a choose a list, I get a "select a view" navigation on the left hand side of the page showing the available views. When a new view is created, it automatically appears on this navigation list. In the online sharepoint, instead there is a view dropdown. I know I can manually setup links on the quick launch but I'm looking for an automatic way to do this. Can the online sharepoint be set up so that when views are added they automatically appear as left-hand links? Or can the "views" dropdown be moved to the left side which would be an acceptable work around? Please note I am unfamiliar with SP designer and I do work with .NET but I dont want to go that route just for this issue - thanks.

• problems with extended classes and overwrite with methods

  - by Marco

  I have a .net website written in C# and will make functionalities that other developers can use. So i will make some default implementation and a developer can overwrite some methods Example: i have a class ShoppingCart and a class Product the class product haves a method getProductPrice the shoppingcart will call the method getProductPrice for calculating the total price of cart The Shoppingcart and Product are in the same project and i will give the developers the .dll so they can't change the source code so we can update the assembly later So they need to make a other project and extend the product class and overwrite the method getProductPrice so they can implement there own logic The problem is that the shoppingcart will not call the extended method but the original If we make already a extended project for the developers and the shoppingcart will call the extended method then we have a circular reference because the extended product needs a reference to product and the shopping cart to the extended product partial classes also don't works because we only can use partials within the same assembly anyone a suggestion ? thanks in advance
