  • Empty constructor or no constructor

    - by Ram
    Hi, I think it is not mandatory to have a default constructor in a class (C#). So in that situation shall I have a empty constructor in the class or I can skip it? Is it a best practice to have a default empty constructor? Class test { test() { } ...... } or Class test { ...... }

  • Django: Breaking up views

    - by Brant
    This is really just a "best practices" question... I find that When developing an app, I often end up with a lot of views. Is it common practice to break these views up into several view files? In other words... instead of just having views.py, is it common to have views_1.py, views_2.py, views_3.py (but named more appropriately, perhaps by category)?

  • Can a script called by XHR reference $_COOKIE?

    - by Christian Mann
    Quick yes/no - I'm building an AJAX application and some scripts require authentication. Can I read $_COOKIE['username'] and $_COOKIE['password'] on the server if the PHP script was called via XHR, whether that be $.get() or $.post()? Side question: Can it also set cookies? Is that considered "good practice"?

  • Hyphens or underscores in CSS and HTML identifiers?

    - by Török Gábor
    As both hyphen (-) and underscore (_) are valid characters in CSS and HTML identifiers, what are the advantages and disadvantages using one or the other? I prefer writing CSS class names with hyphens (e.g. field-text) and underscores for IDs (e.g. featured_content). Is there a best practice or it's only the matter of taste?

  • Use of @keyword in C# -- bad idea?

    - by Robert Fraser
    In my naming convention, I use _name for private member variables. I noticed that if I auto-generate a constructor with ReSharper, if the member is a keyword, it will generate an escaped keyword. For example: class IntrinsicFunctionCall { private Parameter[] _params; public IntrinsicFunctionCall(Parameter[] @params) { _params = @params; } } Is this generally considered bad practice or is it OK? It happens quite frequently with @params and @interface.

  • What's the pythonic way of declaring variables?

    - by the_drow
    Usually declaring variables on assignment is considered a best practice in VBScript or JavaScript , for example, although it is allowed. Why does Python force you to create the variable only when you use it? Since Python is case sensitive can't it cause bugs because you misspelled a variable's name? How would you avoid such a situation?

  • Code Analysis - Treat as Error

    - by Brian Schmitt
    Looking to enable the "Enable code Analysis on Build" feature in Visual Studio. Obviously the Rules are a best practice, and I am working with an existing code base that currently fails many of the rules. I am looking for input as to which rules are the most egregious and should be treated as an Error.

  • Objective-C categories in static library

    - by Vladimir
    Can you guide me how to properly link static library to iphone project. I use staic library project added to app project as direct dependency (target - general - direct dependecies) and all works OK, but categories. A category defined in static library is not working in app. So my question is how to add static library with some categories into other project? And in general, what is best practice to use in app project code from other projects?

  • Auto-generating toString Method

    - by Gordon
    Is it good or bad practice auto-generating toString methods for some simple classes? I was thinking of generating something like bellow where it takes the variable names and produces a toString method that prints the name followed by it's value. private String name; private int age; private double height; public String toString(){ Formatter formatter = new Formatter(); return formatter.format("Name: %s, Age: %d, Height %f", name, age, height).toString(); }

  • To log in stored procedures?

    - by hgulyan
    If you have a long running SP, do you log somehow it's actions or just wait for this message? "Command(s) completed successfully." I assume, that there can be plenty solutions on this subject, but is there any best practice - a simple solution that is frequently used?

  • Factory Method and Cyclic Dependancy

    - by metdos
    If I'm not wrong, because of its nature in factory method there is cyclic dependency: Base class needs to know subclasses because it creates them, and subclasses need to know base class. Having cyclic dependency is bad programming practice, is not it? Practically I implemented a factory, I have problem above, even I added #ifndef MYCLASS_H #define MYCLASS_H #endif I'm still getting Compiler Error C2504 'class' : base class undefined And this error disappers when I remove subclass include from base class header.

  • Advice on software / database design to avoid using cursors when updating database

    - by Remnant
    I have a database that logs when an employee has attended a course and when they are next due to attend the course (courses tend to be annual). As an example, the following employee attended course '1' on 1st Jan 2010 and, as the course is annual, is due to attend next on the 1st Jan 2011. As today is 20th May 2010 the course status reads as 'Complete' i.e. they have done the course and do not need to do it again until next year: EmployeeID CourseID AttendanceDate DueDate Status 123456 1 01/01/2010 01/01/2011 Complete In terms of the DueDate I calculate this in SQL when I update the employee's record e.g. DueDate = AttendanceDate + CourseFrequency (I pull course frequency this from a separate table). In my web based app (asp.net mvc) I pull back this data for all employees and display it in a grid like format for HR managers to review. This allows HR to work out who needs to go on courses. The issue I have is as follows. Taking the example above, suppose today is 2nd Jan 2011. In this case, employee 123456 is now overdue for the course and I would like to set the Status to Incomplete so that the HR manager can see that they need to action this i.e. get employee on the course. I could build a trigger in the database to run overnight to update the Status field for all employees based on the current date. From what I have read I would need to use cursors to loop over each row to amend the status and this is considered bad practice / inefficient or at least something to avoid if you can??? Alternatively, I could compute the Status in my C# code after I have pulled back the data from the database and before I display it on screen. The issue with this is that the Status in the database would not necessarily match what is shown on screen which just feels plain wrong to me. Does anybody have any advice on the best practice approach to such an issue? It helps, if I did use a cursor I doubt I would be looping over more than 1000 records at any given time. Maybe this is such small volume that using cursors is okay?

  • Should ActionResult perform other tasks too

    - by Ori
    In Asp.net MVC one is encouraged to derive custom ActionResults, however should these classes handle other tasks unrelated to views, perhaps a EmailActionResult would render a view then send an email. What is best practice for the class ActionResult, is it only view specific? I want to keep things DRY too. Should the sending of the email be factored into a service class? perhaps using a filter would work. what are your thoughts?

  • Using pointers in PHP.

    - by Babiker
    I ask this question because i learned that in programming and designing, you must have a good reason for decisions. I am php learner and i am at a crossroad here, i am using simple incrementation to try to get what im askin across. I am certainly not here to start a debate about the pros/cons of pointers but when it comes to php, which is the better programming practice: function increment(&$param) { $param++; } Or function increment($param){ return $param++; } $param = increment($param);
