  • Java: Interface vs Abstract Class (regarding fields)

    - by lifeR00t
    From what I have gathered, I want to force a class to use particular private fields (and methods) I need an abstract class because an interface only declares public/static/final fields and methods. Correct?? I just started my first big java project and want to make sure I'm not going to hurt myself later :)

  • Swing UI does not have native OS look

    - by Virat Kadaru
    I am building an application in java swing and I am using the following code to give the UI a native OS look try { UIManager.setLookAndFeel( UIManager.getSystemLookAndFeelClassName()); } catch (Exception e) { e.printStackTrace(); } On a OS X, the look is fine, but on windows (XP and 7) the buttons look like this. I have used this exact same code on other projects and it works fine. But in this particular project I get a completely different look. Thanks in advance!

  • Silverlight 4 missing from VS 2010

    - by iheartso
    Hello, When I start a new Visual C# Silverlight project in the official release version (not the beta or the release candidate--the official release version) of Visual Studio 2010, I get only Silverlight 3 as an option in the Silverlight Version dropdown at the New Silverlight Application dialog box. I have installed SL 4, the SL4 tools for VS 2010, to no avail. I am running Windows XP SP3. Any ideas??? Thank you, Jon

  • Export Flash Animation to ActionScript

    - by user107715
    Hi I would like to make an animation using some tool (like e.g. Flash CS) and then export it for ActionScript. I thought this could be done in Flash CS but I just tried it by making an animation, converting it to a symbol and then selecting "Export for ActionScript". The problem: in the project folder there are no ActionScript classes generated. Am I doing it wrong or do I have to use a different tool to do the animation? Many many thanks for your help, Gloria

  • Deploying patches and new versions.

    - by 0plus1
    I'm deveoping a big project, I have the dev folder (connected to a specific subdomain) then the "real" folder, the live one. When I'm ready to push patches or whole new versions I'm currently copying the files individually, is there a program that can help me do this task? Keep in mind that some files (the config one and the htacess) must never change in the live version. Thank you

  • Which JavaScript graphics library has the best performance?

    - by DNS
    I'm doing some research for a JavaScript project where the performance of drawing simple primitives (i.e. lines) is by far the top priority. The answers to this question provide a great list of JS graphics libraries. While I realize that the choice of browser has a greater impact than the library, I'd like to know whether there are any differences between them, before choosing one. Has anyone done a performance comparison between any of these?

  • Projects with browsable source using dependency injection w/ guice?

    - by André
    I often read about dependency injection and I did research on google and I understand in theory what it can do and how it works, but I'd like to see an actual code base using it (Java/guice would be preferred). Can anyone point me to an open source project, where I can see, how it's really used? I think browsing the code and seeing the whole setup shows me more than the ususal snippets in the introduction articles you find around the web. Thanks in advance!

  • How to take handwritten notes as image in android?

    - by krammer
    I am trying to develop an android application that could store whatever the user writes on screen as an image. For example, if the user writes "Co" followed by "ol" and presses OK, the text is stored as "Cool" as an image in a field on the form displayed on the phone. (No handwriting recognition or OCR required) I have seen the Canvas class in Android, but how would you concatenate all the letters/set of characeters and convert them to image ? Is there any open source project that does something similar ?

  • Investment advice data dump analysis

    - by portoalet
    For my year-end pet project, I'd like to analyze investment advices and their correlation to the stock market performance. The problem is, where do I get the dump of investment advice data (free) ? something like stackoverflow.com data dump will be nice. Or maybe it's easier to do distributed crawling and crawl the public finance webpages for investment advices? Investment advice is buy/sell advice for stocks/forex, issued by institution/investment advisor.

  • Is arithmetic overflow/underflow generally checked in .Net framework methods?

    - by YWE
    For example, let's use the Add method of the ArrayList class. If I am using the default compiler settings in Visual Studio C# project in which arithmetic overflow is not checked, would ArrayList.Add() throw an OverflowException if I added too many items? Would surrounding the method call with checked or unchecked make any difference? BTW, I would write a test program to determine the answer to this question if I had Visual Studio available to me right now.

  • In partial view: "The model item passed into the dictionary is of type"

    - by Dave
    I lack understanding of some basic MVC concepts, despite all my searching. I created an MVC project in Visual Studio, which contains the partial view _LogOnPartial.shtml. I just want to access information within the view pertaining to the user, to put in a user dropdown menu. When I try to put this at the top of the partial view cshtml page I get the above error: @model MyProject_MVC.Models.UserRepository When I try this I also get an error: @Html.Partial("_LogOnPartial", MyProject_MVC.Models.UserRepository) 'MyProject_MVC.Models.UserRepository' is a 'type', which is not valid in the given context

  • Scrum backlog sizing is taking forever

    - by zachary
    I work on a huge project. While we program we end up meeting for endless backlog sizing sessions where all the developers sit down with the team and size user stories. Scrum doubters are saying that this process is taking too long and development time is being wasted. My question is how long should it take to size a user story on average? And does anyone have any tips to make these sizing sessions go quicker?
