  • PHP class data implementation

    - by Bakanyaka
    I'm studying OOP PHP and have watched two tutorials that implement user login\registration system as an example. But implementation varies. Which way will be more correct one to work with data such as this? Load all data retrieved from database as array into a property called something like _data on class creation and further methods operate with this property Create separate properties for each field retrieved from database, on class creation load all data fields into respective properties and operate with that properties separately? Then let's say I want to create a method that returns a list of all users with their data. Which way is better? Method that returns just an array of userdata like this: Array([0]=>array([id] => 1, [username] => 'John', ...), [1]=>array([id] => 2, [username] => 'Jack', ...), ...) Method that creates a new instance of it's class for each user and returns an array of objects

  • Repainting a window with a new scene with winapi (beginner question)

    - by user90760
    I'm following theForger's win32 API tutorial in order to create a GUI for a project. I've successfully made simple, one window applications, but I can't figure out how to repaint an entire window with new information. As an example: I have five buttons corresponding to five colors on the main application window. When a user clicks a color button, the entire window is repainted such that: 1. all five buttons are removed and a new "back" button is replaced, 2. the background is colored the color that was picked. I'm able to change the background color by trapping the button pressed message in my wndproc, but I can't figure out how to change the entire window with a new "scene" (removing the color buttons and adding a back button). This seems like a trivial task, but I can't find a solution in tutorials. Do I need to declare a new windows class with the back button and then have my button trap create a window of this class?

  • Architecture or Pattern for handling properties with custom setter/getter?

    - by Shelby115
    Current Situation: I'm doing a simple MVC site for keeping journals as a personal project. My concern is I'm trying to keep the interaction between the pages and the classes simplistic. Where I run into issues is the password field. My setter encrypts the password, so the getter retrieves the encrypted password. public class JournalBook { private IEncryptor _encryptor { get; set; } private String _password { get; set; } public Int32 id { get; set; } public String name { get; set; } public String description { get; set; } public String password { get { return this._password; } set { this.setPassword(this._password, value, value); } } public List<Journal> journals { get; set; } public DateTime created { get; set; } public DateTime lastModified { get; set; } public Boolean passwordProtected { get { return this.password != null && this.password != String.Empty; } } ... } I'm currently using model-binding to submit changes or create new JournalBooks (like below). The problem arises that in the code below book.password is always null, I'm pretty sure this is because of the custom setter. [HttpPost] public ActionResult Create(JournalBook book) { // Create the JournalBook if not null. if (book != null) this.JournalBooks.Add(book); return RedirectToAction("Index"); } Question(s): Should I be handling this not in the property's getter/setter? Is there a pattern or architecture that allows for model-binding or another simple method when properties need to have custom getters/setters to manipulate the data? To summarize, how can I handle the password storing with encryption such that I have the following, Robust architecture I don't store the password as plaintext. Submitting a new or modified JournalBook is as easy as default model-binding (or close to it).

  • Creating Java EE Projects with Maven

    - by M.C.
    I've been developing Java EE web apps with Eclipse for about a year. My employer doesn't use Maven, but the more I read about it, the more convinced I am that Maven + Hudson will be greatly beneficial for us. First, though, I have to become comfortable with those technologies in my spare time, so that I can create a proof-of-concept. Right now, I'm still a Maven newbie. Is there a set of best practices for creating Java EE web apps with Maven? For example, I could create a project with a basic archetype and then add all of the necessary JARs by putting dependencies in the POM for the servlet container, EJB, EclipseLink, etc... That might work, but it might not be the best way to do it. I'd greatly appreciate any guidance that you could provide on this topic.

  • Need Advice: What to program?

    - by newbie
    Good day! Our professor asked us to create a Web-based program using JSP and JDBC. The problem is I don't have any idea what to program.

Can anyone give me an idea what is suitable project for beginners to start with? (Note: Address Books / ATM Transactions are not allowed). Do you have sample website so I have a reference? Thank you.

  • Letting the user draw a Polygon Body and Image

    - by Siddharth
    In my game, I want to provide the user with a drawing feature. By free hand drawing, the user creates a polygon shape. Then, in my game implementation, I have to create a body for the found vertices and generate an image based on that polygon shape. My problem is how to create an image that matches the user-provided vertices. I've heard that cocos2d has something called Image Masking. I don't understand how I could implement it in AndEngine. Could someone help?

  • Nautilus (File) 3.10.1 how to lock drag and drop bookmarks

    - by Davide Marchi
    From the new Nautilus releases exist the ability to create shortcut/bookmarks simply by drag&drop folder onto the nautilus left panel; However, this behavior can unintentionally create additional bookmarks if you are not very accurate when dragging files to bookmarks, especially by people with little experience in the use of computer. How is possible to disable the drag&drop bookmarks creation? Or ideally should be planning to implement the drag & drop mode only if you are running in conjunction with the press of a key on the keyboard ..

  • Connection make b/w iphone to windows pc-rajay [on hold]

    - by Rajay
    I Need to create connection between ios to windows by using socket programming in ios. I'm trying to to use an application to communicate with Windows via sockets. At the minimum, I'm trying to at least figure out how I can create a connection from the iPhone (maybe using the iPhone to ping the Windows machine?) I'm not really clear on where I need to start. I'm pretty new to iOS development in general, and brand new to socket/network programming. I've tried several tutorials that haven't gotten me far. My goal is: Connect to a server via sockets (the server will be a Windows machine with a service waiting for incoming connections from the iPhone) If possible, I would like to write/build the client piece first, but I have been lost thus far. Hopefully the nice folks in the SO community can lend a hand and point me in the right direction.

  • How to resize(increase) a root+home cloned partition from a smaller hdd?

    - by saulo
    Here is my story: I had a hd failing so I cloned it with dd to larger 500gb hd. It seemed to have worked well, but I have all this unallocated free space at the end of the disk (230gb). I tried to used gparted from a liveUSB to allocate all this space to my root+home partition (other than that I only have a small extended partition with the swap). It won't let me do this. I can only create another partition, or allocate the free space to the extend partition. I can however reduce the size of the root+home partition since I wasn't using all the space Is there a way to put this free space to my root+home partition after all? Or do I have to go with another partition. If so I'd like to separate my home from the root, reduce the root partition and create a ext4 logical home partition. What would be the best safest way to do this? Thanks so much in advance, aloha

  • Separate parts of a game engine [on hold]

    - by user272716
    I'm pretty new in developing videogames. By now I only used SDL with C/C++ to create games. I'm currently learning OpenGL and I realized that to be fluid and easy to maintain the code must be logically separated. Since I want to use OpenGLES on iOS and Android I was wondering how the engine must be imagined in a technical way, some questions came up: Do I have to separate input/update functions from draw functions in different threads? Is there only one proper way to think a game engine/loop? What kind of assets should I use to create a 3D game using openGl ES to get better performance?

  • As a consultant, how can I amaze my clients?

    - by user20326
    I am about to form a small consulting company and with a few friends and I am curious about how/what you do to amaze and create happy long lasting clients? This is of course besides the standard points like delivering on time, charge fair amount, deliver quality, and deliver what they really want. What other techniques do you use to amaze and create long lasting clients? (and to stand out compare to the competition) For example: Gifts? Happening and events? Night out at the pub?
