  • Code jumps out of a jar and runs? What is causing this?

    - by Mike
    I am trying to get a sample program working with JUNG, a graphing tool in Java. I downloaded and referenced all the .jar files in eclipse so my project hierarchy looks like this: In Test.java I have the following code: public class Test { static public void main() { System.out.print("Hello"); }} For some reason though when I try to run it as a Java Application by right clicking on Jung test in the project hierarchy I am presented with a bunch of classes. My Test.java isn't on the list so if I just leave it as ** and press ok it starts running a program that is dynamically adding nodes and vertexes to a graph. I can't seem to figure out what code its actually executing. I know java but stuff like this with the jar files seems to be getting lost on me. Any ideas? Thanks

  • Scala model-view-presenter, traits

    - by Ralph
    I am a fan of Martin Fowler's (deprecated) model-view-presenter pattern. I am writing a Scala view class containing several button classes. I would like to include methods to set the action properties of the buttons, to be called by the presenter. A typical code fragment looks like this: private val aButton = new JButton def setAButtonAction(action: Action): Unit = { aButton.setAction(action) } This code is repeated for each button. If Java/Scala had the C preprocessor, I would create a macro to generate this code, given the button name (no lectures on the evils of the C preprocessor, please). This code is obviously very verbose and repetitive. Is there any better way way to do this in Scala, perhaps using traits? Please hold the lectures about scala.swing. I looking for a general pattern here.

  • Cleanly handling events

    - by nkr1pt
    I have code similar to this in all my observer classes that handle events fired by an event bus class. As you can see there are a lot of instanceof checks to choose the path of action needed to appropriately handle events, and I was wondering if this could be done more cleanly, eliminating the instanceof tests? @Override public void handleEvent(Event event) { if (event instanceof DownloadStartedEvent) { DownloadStartedEvent dsEvent = (DownloadStartedEvent)event; dsEvent.getDownloadCandidateItem().setState(new BusyDownloadingState()); } else if (event instanceof DownloadCompletedEvent) { DownloadCompletedEvent dcEvent = (DownloadCompletedEvent)event; dcEvent.getDownloadCandidateItem().setState(new FinishedDownloadingState()); DownloadCandidate downloadCandidate = dcEvent.getDownloadCandidateItem(). getDownloadCandidate(); if (downloadCandidate.isComplete()) { // start extracting } } else if (event instanceof DownloadFailedEvent) { DownloadFailedEvent dfEvent = (DownloadFailedEvent)event; dfEvent.getDownloadCandidateItem().setState(new FailedDownloadingState()); } }

  • C# Class Instantiation Overflow

    - by Goober
    Scenario I have a C# Win Forms App, where the Main Form contains a loop that creates 3000 Instances of another form (Form B). Inside Form B there are a large number of properties and fields and a bunch of methods that do a fair amount of processing. Question Will the creation of 3000 of these classes give me problems? I'm thinking along the lines of memory exceptions? I've had 1 or 2 already, and I've also had an exception that says something along the lines of "Something went bang and this is usually a sign of corrupt memory somewhere else". Setup I'm using a DevExpress Ribbon Form and I haven't implemented Dispose on anything....Do I need to? Help greatly appreciated.

  • Programatically prevent ASP .NET AJAX scripts from rendering

    - by cbp
    Does anyone know of a way that I can stop all the .NET AJAX scripts from rendering, even if a ScriptManager exists on the page? The ScriptManager's Visible property has been overridden and disabled so that you receive a NotImplementedException if you try to set the Visible property. The reason I would like to do this is that I don't want these large chunks of javascript all over my pages when they are not required. The ScriptManager needs to be included on the master page to ensure that only one ScriptManager is added, but it would be stupid to to have to have two versions of the same master page - one ajax enabled and one not. Edit: I am actually using Telerik's RadScriptManager with RadAjax, in case anyone knows a method using these classes instead.

  • Maximizing the number of threads to fully utilize all available resources without hindering overall

    - by Matt
    Let's say I have to generate a bunch of result files, and I want to make it as fast as possible. Each result file is generated independently of any other result file; in fact, one could say that each result file is agnostic to every other result file. The resources used to generate each result file is also unique to each. How can I dynamically decide the optimal number of threads to run simultaneously in order to minimize the overall run time? Is my only option to write my own thread manager that watches performance counters and adjust accordingly or does there exists some solid classes that already accomplish this?

  • Getting Prepared/Planning

    - by The.Anti.9
    For the first time, I am trying to create a rather large .NET project. I think the largest one I have made so far was about 6 classes, but this one is already at 14. For the section I'm starting to work on, I'm having some trouble putting everything together in my head, which is what I normally do. I think it's just a little too complex for that. I want to plan it out, and I want some way to visualize it and be able to play with it and manipulate the structure easily. Is there any sort of (free) program I can use to do this?

  • Declare 2 types inside using statement gives compile error?

    - by citronas
    I want to use this line of code: using (ADataContext _dc = new ADataContext(ConnectionString), BDataContext _dc2 = new BrDataContext(ConnectionString)){ // ...} This gives a compile error: Cannot use more than one type in a for, using, fixed or declartion statement. I thought this was possible? MSDN says it is: http://msdn.microsoft.com/en-us/library/yh598w02%28VS.80%29.aspx In the MSDN sample code Font is used, which is class and thereby a reference type as well as my two DataContext classes. What went wrong here? How does my attempt differ from the MSDN sample?

  • iPhone: Chained views

    - by Michael
    I want to have dynamically created views and be able to scroll(change views like in camera roll) either from my program or user should also be able to do that. The views should contain only a simple text. Each view has to replace other, so they are like chained. The other example is the screenshots of applications in app store application details. I don't know which classes to check/start so if anyone can give me an idea of how this could be designed I would appreciate it.

  • Sparx Enterprise Architect conversion (from source to UML)

    - by user228938
    I need to make a UML class diagram for a project. I used Sparx Enterprise Architect in the past to generate source code from a diagram so I'm using that. The project is complete so all of the code is done and I don't really want to write all the classes / functions manually, so I was trying to generate the diagram from the source code but can't seem to find a way to do it. I searched online and on their website but nothing. Any help appreciated. Thanks in advance.

  • What are the pros/cons to these 2 ways of defining parameters for a web service method

    - by Antony Scott
    I have an existing web service I need to expand, but it has not gone into production yet. So, I am free to change the contracts as I see fit. But I am not sure of the best way to define the methods. I am leaning towards Method 2 for no other reason than I cannot think of good names to give the parameters classes! Are there any major disadvantages to using Method 2 over Method 1? Method 1 [DataContract(Namespace = Constants.ServiceNamespace)] public class MyParameters { [DataMember(Order = 1, IsRequired = true)] public int CompanyID { get; set; } [DataMember(Order = 2, IsRequired = true)] public string Filter { get; set; } } [ServiceContract(Namespace = Constants.ServiceNamespace)] public interface IMyService { [OperationContract, FaultContract(MyServiceFault)] MyResult MyMethod(MyParameters params); } Method 2 public interface IMyService { [OperationContract, FaultContract(MyServiceFault)] MyResult MyMethod(int companyID, string filter); }

  • Problems with listening for an event in child object in Actionscript

    - by Raigomaru
    I have two classes. The first one (the starting class): package { import flash.display.Sprite; import flash.events.KeyboardEvent; import tetris.*; public class TetrisGame extends Sprite { private var _gameWell:Well; public function TetrisGame() { _gameWell = new Well(); addChild(_gameWell); } } } The second: package tetris { import flash.display.Sprite; import flash.events.KeyboardEvent; public class Well extends Sprite { public function Well() { super(); addEventListener(KeyboardEvent.KEY_DOWN, onKeyboard); } private function onKeyboard(event:KeyboardEvent):void { //some code is here } } } But when I press any buttons on my keyboard, the child class Well doesn't have any reaction. What's the problem?

  • SQLAlchemy declarative syntax with autoload in Pylons

    - by Juliusz Gonera
    I would like to use autoload to use an existings database. I know how to do it without declarative syntax (model/_init_.py): def init_model(engine): """Call me before using any of the tables or classes in the model""" t_events = Table('events', Base.metadata, schema='events', autoload=True, autoload_with=engine) orm.mapper(Event, t_events) Session.configure(bind=engine) class Event(object): pass This works fine, but I would like to use declarative syntax: class Event(Base): __tablename__ = 'events' __table_args__ = {'schema': 'events', 'autoload': True} Unfortunately, this way I get: sqlalchemy.exc.UnboundExecutionError: No engine is bound to this Table's MetaData. Pass an engine to the Table via autoload_with=<someengine>, or associate the MetaData with an engine via metadata.bind=<someengine> The problem here is that I don't know where to get the engine from (to use it in autoload_with) at the stage of importing the model (it's available in init_model()). I tried adding meta.Base.metadata.bind(engine) to environment.py but it doesn't work. Anyone has found some elegant solution?

  • Best way to model map values in Grails?

    - by Mulone
    Hi guys, I have to implement map values in my Grails app. I have a class that can contain 0..N OsmTags, and the key is unique. In Java I would model this with a Map in each object, but I don't know how to map classes in Grails. So I defined this class: class OsmTag { /** OSM tag name, e.g. natural */ String key /** OSM tag value, e.g. park */ String value static constraints = { key blank:false, size:2..80,matches:/[\S]+/, unique:false value blank:false, size:1..250,matches:/[\S]+/, unique:false } } That works ok, but it's actually quite ugly because the tag key is not unique. Is there a better way to model this issue? Cheers

  • Cross-platform GUI toolkits with WPF-style composition capabilities

    - by Alexey Romanov
    A huge advantage of WPF over, say, WinForms is its composability. To quote Programming WPF: One level up, WPF provides its “content model,” which allows any control to host any group of other controls. You don’t have to build special BitmapButton or IconComboBox classes; you put as many images, shapes, videos, 3D models, or whatever into a Button (or a ComboBox, ListBox, etc.) as suit your fancy. Are there any cross-platform GUI frameworks (preferably with Java bindings) out there which also let you do this?

  • Creating own LiveWallpaperPreview?

    - by Nick
    Hi, I would like to create my own LiveWallpaperPreview, i.e. to show the user a fullscreen preview of what the selected Live Wallpaper looks like (without the "Set Wallpaper" and "Settings" button that the built-in preview has). Rebuilding the LivePicker-Class from 2.1 (android.git.kernel.org) works fine, so I am able to select a wallpaper to be previewed, but the actual LiveWallpaperPreview-Class tries to import the following private Interfaces/Classes: import android.service.wallpaper.IWallpaperConnection; import android.service.wallpaper.IWallpaperService; import android.service.wallpaper.IWallpaperEngine; import android.service.wallpaper.WallpaperSettingsActivity; Is there any way to display a LiveWallpaper in my app without resorting to using the private APIs (which I obviously don't want to do)? Thanks! Nick

  • Can the get of a property be abstract and the set be virtual?

    - by K. Georgiev
    I have a base class like this: public class Trajectory{ public int Count { get; set; } public double Initial { get; set { Count = 1; } } public double Current { get; set { Count ++ ; } } } So, I have code in the base class, which makes the set-s virtual, but the get-s must stay abstract. So I need something like this: ... public double Initial { abstract get; virtual set { Count = 1; } } ... But this code gives an error. The whole point is to implement the counter functionality in the base class instead in all the derived classes. So, how can I make the get and set of a property with different modifiers?

  • C++ Class Inheritance architecture - preventing casting

    - by Some One
    I have a structure of base class and a couple of inherited classed. Base class should be pure virtual class, it should prevent instantiation. Inherited classes can be instantiated. Code example below: class BaseClass { public: BaseClass(void); virtual ~BaseClass(void) = 0; }; class InheritedClass : public BaseClass { public: InheritedClass1(void); ~InheritedClass1(void); }; class DifferentInheritedClass : public BaseClass { public: DifferentInheritedClass(void); ~DifferentInheritedClass(void); }; I want to prevent the following operations to happen: InheritedClass *inherited1 = new InheritedClass(); DifferentInheritedClass *inherited2 = new DifferentInheritedClass (); BaseClass *base_1 = inherited1; BaseClass *base_2 = inherited2; *base_1 = *base_2;

  • design using a readonly class in c#

    - by edosoft
    Hi Small design question here. I'm trying to develop a calculation app in C#. I have a class, let's call it InputRecord, which holds 100s of fields (multi dimensional arrays) This InputRecordclass will be used in a number of CalculationEngines. Each CalculcationEngine can make changes to a number of fields in the InputRecord. These changes are steps needed for it's calculation. Now I don't want the local changes made to the InputRecord to be used in other CalculcationEngine's classes. The first solution that comes to mind is using a struct: these are value types. However I'd like to use inheritance: each CalculationEngine needs a few fields only relevant to that engine: it's has it's own InputRecord, based on BaseInputRecord. Can anyone point me to a design that will help me accomplish this?

  • Quickly generate/publish RSS feeds from ASP.NET projects?

    - by jdk
    Under a timeline, therefore the salient point is "quickly" and willing to throw some $ at it too (doesn't have to be a free solution). Looking for an RSS feed generator usuable in .NET framework 2.0. Ideally it would be easy to use (inferred quick) but flexible enough to support the multiple standards (shown part way down this page). We have the business classes in .NET and want to publish RSS feeds on the ASP.NET website. Any software that's good? Doesn't have to be free. Must support .NET framework 2.0 Thanks.

  • Overcoming C limitations for large projects

    - by Francisco Garcia
    One aspect where C shows its age is the encapsulation of code. Many modern languages has classes, namespaces, packages... a much more convenient to organize code than just a simple "include". Since C is still the main language for many huge projects. How do you to overcome its limitations? I suppose that one main factor should be lots of discipline. I would like to know what you do to handle large quantity of C code, which authors or books you can recommend.
