  • OOP + MVC advice on Member Controller

    - by dan727
    Hi, I am trying to follow good practices as much as possible while I'm learning using OOP in an MVC structure, so i'm turning to you guys for a bit of advice on something which is bothering me a little here. I am writing a site where I will have a number of different forms for members to fill in (mainly data about themselves), so i've decided to set up a Member controller where all of the forms relating to the member are represented as individual methods. This includes login/logout methods, as well as editing profile data etc. In addition to these methods, i also have a method to generate the member's control panel widget, which is a constant on every page on the site while the member is logged in. The only thing is, all of the other methods in this controller all have the same dependencies and form templates, so it would be great to generate all this in the constructor, but as the control_panel method does not have the same dependencies etc, I cannot use the constructor for this purpose, and instead I have to redeclare the dependencies and same template snippets in each method. This obviously isn't ideal and doesn't follow DRY principle, but I'm wondering what I should do with the control_panel method, as it is related to the member and that's why I put it in that controller in the first place. Am I just over-complicating things here and does it make sense to just move the control_panel method into a simple helper class? Here are the basic methods of the controller: class Member_Controller extends Website_Controller { public function __construct() { parent::__construct(); if (request::is_ajax()) { $this->auto_render = FALSE; // disable auto render } } public static function control_panel() { //load control panel view $panel = new View('user/control_panel'); return $panel; } public function login() { } public function register() { } public function profile() { } public function household() { } public function edit_profile() { } public function logout() { } }

  • Sharing class member data between sub components

    - by Tim Gradwell
    I have an aggregate 'main' class which contains some data which I wish to share. The main class also has other class members. I want to share the data with these other class members. What is the correct / neatest way to do this? The specific example I have is as follows. The main class is a .net Form. I have some controls (actually controls within controls) on the main form which need access to the shared data. Main Form - DataX - DataY - Control1 -- Subcontrol1 - Control2 -- SubControl2 SubControls 1 and 2 both wish to access DataX and DataY. The trouble is, I feel like better practice (to reduce coupling), would be that either subcontrols should not know about Main Form, or Main Form should not know about subcontrols - probably the former. For subcontrols not to know about Main Form, would probably mean Main Form passing references to both Controls 1 and 2, which in turn would pass the references on to SubControls 1 and 2. Lots of lines of code which just forward the references. If I later added DataZ and DataW, and Controls 3 and 4 and SubControls 3 and 4, I'd have to add lots more reference forwarding code. It seems simpler to me to give SubControls 1 and 2 member references to Main Form. That way, any sub control could just ask for MainForm.DataX or MainForm.DataY and if I ever added new data, I could just access it directly from the sub controls with no hassle. But it still involves setting the 'MainForm' member references every time I add a new Control or Subcontrol. And it gives me a gut feeling of 'wrong'. As you might be able to tell I'm not happy with either of my solutions. Is there a better way? Thanks

  • SSIS with different table structures

    - by Grace
    I have a flat file source from Excel that has a structure like this: **People** Day1 Day2 Day3 Day4 Person1 someValue ... Person2 Person3 And i would like the package to put this information in a database with standard columns 'Person', 'Day', 'Value'. Does anybody know how to do this - at the moment because the days are going along the top, the package is assuming these are seperate data columns when they are not really and the mapping is not working.

  • "Ambiguous column name" error on one particular server

    - by jazbit
    This simple query throws the "Ambiguous column name TaskID" error on one db-server only. This is ridiculous. We tested this with the same database structure on different servers and different versions of ms sql (2005/2008), and it's only THIS particular client's server that throws the error. I'm actually frustrated. SELECT Tasks.TaskID FROM Tasks INNER JOIN TaskHelpers ON TaskHelpers.TaskID = Tasks.TaskID order by TaskID Yes, I know I can put "Tasks.TaskID" into the order by clause, but for some reasons I can't.

  • Which controls are being used?

    - by Jack
    Are there any tools available that allow you to 'look' at any given application and show you which WinForm controls are being used in that application? I happen to have an app which I like the GUI of, and I want to use a similar structure in my own app. Instead of developing these controls myself, it may be easier to buy them, if only I can spot which are being used... Any suggestions?

  • Writing Logs to an XML File with .NET

    - by JL
    I am storing logs in an xml file... In a traditional straight text format approach, you would typically just have a openFile... then writeLine method... How is it possible to add a new entry into the xml document structure, like you would just with the text file approach?

  • Windows [C++] - Creating new folders if they don't exist for fopen

    - by Gbps
    I have a C++ program that takes user input for fopen in order to initiate a file write. Could someone help me find a function which will return a FILE* and use the Windows specific version of mkdir in order to create the folder structure for fopen to never fail to open a new file in the specified location because one of the folders does not exist. Thanks a bunch!

  • Using .htaccess to change my website URLs

    - by James P
    I have some pages organised like this: http://localhost/index.html http://localhost/download.html http://localhost/contact.html And I need them changed to suit the following URL structure: http://localhost/ http://localhost/download http://localhost/contact Without making sub directories and putting in pages as index.html. As far as I know .htaccess can be used for this, but I have no idea what I need to add to my .htaccess file to make this work. Can anyone provide some help? Thanks.

  • How can I automatically refactor my classes to use the default namespace for the folder they're in?

    - by Daniel Schaffer
    I've been playing around with the structure of my project, and I'd like to reset the namespaces of my classes to what the default would be. That is, the default namespace for the project, plus each of the folders in the hierarchy. It's not as simple as just find + replace, since I've both added and renamed some folders, and files from some namespaces were split into multiple other namespaces. I'm using VS 2010.

  • How do you handle large projects?

    - by cam
    I've just inherited a large project previously coded by about 4-5 people. The documentation consists of comments, and is not very well written. I have to get up to date on this project. How do I start? It consists of many different source files. Do you just dig in? Are there tools that can help visualize the structure/flow?

  • confusing java data structures

    - by London
    Maybe the title is not appropriate but I couldn't think of any other at this moment. My question is what is the difference between LinkedList and ArrayList or HashMap and THashMap . Is there a tree structure already for Java(ex:AVL,Black-white) or balanced or not balanced(linked list). If this kind of question is not appropriate for SO please let me know I will delete it. thank you

  • What Are Collections Implemented As In VB6?

    - by Tom Tresansky
    So a collection in VB6 keeps track of a key for each object, and you can look up the object by its key. Does that mean collections are implemented as some sort of hashtable under the hood? I realize you can have multiple items with the same key in a collection, hence the SOME SORT. Anybody know what type data structure a VB6 collection is supposed to represent?

  • How to determine whether a database has been changed or not ?

    - by Locksfree
    I have a need to determine if a database on a MS SQL Server has changed between two distinct moments. The change can be structural or data-related and the check should be generic (i.e. independant of the structure of the database). Preferably, I'd like the check to be T-SQL based or with SMOs, not file based. I checked on MSDN but I haven't found anything relevant so far.

  • XML in Authorware 7.01

    - by Mikael
    Let me explain the setup that is being used. Right now I have an authorware program which loads an ocx control. This control receives data in the form on an XML string. This part is working properly. However I need parse this XML string in authorware and have not been successful. I have been trying to use the XMLParser Xtra. The documentation listed here shows how to create a new XMLParser object and then shows how to call the object but never explains how to link the Parser to a XML file or XML string. The information I have been using can be found here https://www.adobe.com/livedocs/authorware/7/using_aw_en/wwhelp/wwhimpl/common/html/wwhelp.htm?context=Using_Authorware_7&file=09_va110.htm#224295 I need more information on how to Parse XML with this function or if there is another way to do this in Authorware. As a side note the documentation says it cannot create or append to XML, I will need to do this also inside of Authorware. Is this possible and if so, how?
