  • Do console apps run faster than GUI apps?

    - by omair iqbal
    I am relatively new to world of programming. I have a few performance questions: Do console apps run faster than apps with a graphical user interface? Are languages like C and Pascal faster than object oriented languages like C++ and Delphi? I know language speed depends more on compiler than on language itself, but do compilers for procedural languages produce faster code than OO ones (including C++ compilers that can produce C code)?

  • How to get the FPS from a JavaFX scene?

    - by valmar
    I am currently writing a small graphical performance test benchmark for JavaFX. Thus, I need to get the current FPS at which the JavaFX scene is being refreshed. So far, I haven't found a solution how to accomplish this. Does anyone know if there is some kind of event that I could use in order to get the FPS?

  • Creating an intro followed by a loop

    - by voodoo555
    Hey everybody, I just recorded some song and cut it into two parts. The first part contains an intro and the second is supposed to loop. What I want to do now, is to have a simple graphical animation (5 keyframes or so) that loops as well, while the music plays along. There's probably a simple solution to it, when you're familiar with AS. Unfortunately this is the first thing I've ever tried to do with Flash. I'm using Flash CS4. Greetings

  • N-tier Repository POCOs - Aggregates?

    - by Sam
    Assume the following simple POCOs, Country and State: public partial class Country { public Country() { States = new List<State>(); } public virtual int CountryId { get; set; } public virtual string Name { get; set; } public virtual string CountryCode { get; set; } public virtual ICollection<State> States { get; set; } } public partial class State { public virtual int StateId { get; set; } public virtual int CountryId { get; set; } public virtual Country Country { get; set; } public virtual string Name { get; set; } public virtual string Abbreviation { get; set; } } Now assume I have a simple respository that looks something like this: public partial class CountryRepository : IDisposable { protected internal IDatabase _db; public CountryRepository() { _db = new Database(System.Configuration.ConfigurationManager.AppSettings["DbConnName"]); } public IEnumerable<Country> GetAll() { return _db.Query<Country>("SELECT * FROM Countries ORDER BY Name", null); } public Country Get(object id) { return _db.SingleById(id); } public void Add(Country c) { _db.Insert(c); } /* ...And So On... */ } Typically in my UI I do not display all of the children (states), but I do display an aggregate count. So my country list view model might look like this: public partial class CountryListVM { [Key] public int CountryId { get; set; } public string Name { get; set; } public string CountryCode { get; set; } public int StateCount { get; set; } } When I'm using the underlying data provider (Entity Framework, NHibernate, PetaPoco, etc) directly in my UI layer, I can easily do something like this: IList<CountryListVM> list = db.Countries .OrderBy(c => c.Name) .Select(c => new CountryListVM() { CountryId = c.CountryId, Name = c.Name, CountryCode = c.CountryCode, StateCount = c.States.Count }) .ToList(); But when I'm using a repository or service pattern, I abstract away direct access to the data layer. It seems as though my options are to: Return the Country with a populated States collection, then map over in the UI layer. The downside to this approach is that I'm returning a lot more data than is actually needed. -or- Put all my view models into my Common dll library (as opposed to having them in the Models directory in my MVC app) and expand my repository to return specific view models instead of just the domain pocos. The downside to this approach is that I'm leaking UI specific stuff (MVC data validation annotations) into my previously clean POCOs. -or- Are there other options? How are you handling these types of things?

  • Auto-Completion in Unix VI editor

    - by IllustratedInsomnia
    Hey guys, after using graphical IDE's like Visual Studio, I'm used to pressing CTRL+Space to auto-complete a variable or function name. Now, I know such a thing isn't completely possible in VI, but I heard there was a list of commands that could be mapped that allowed automatic completion of variables and functions in the current file opened. Does anyone know what this sequence is? Thanks in advance.

  • Weighted Average and Ratings

    - by Danten
    Maths isn't my strong point and I'm at a loss here. Basically, all I need is a simple formula that will give a weighted rating on a scale of 1 to 5. If there are very few votes, they carry less influence and the rating pressess more towards the average (in this case I want it to be 3, not the average of all other ratings). I've tried a few different bayesian implementations but these haven't worked out. I believe the graphical representation I am looking for could be shown as: ___ / ___/ Cheers

  • Using GitNub with Git

    - by Mike Silvis
    I'm trying to use GitNub, a graphical GUI for Git, and for some reason upon installing the software running the command 'nub' in the terminal doesn't seem to launch anything for me. I am running Mac OS X version 10.6.3 Gitnub version 0.9.1 I have copied the GitNub.app to my applications folder and created a new folder under /usr/local/ called "bin" to put the 'nub' executable inside of it.

  • I'm tired of JButtons, how can I make a nicer GUI in java ?

    - by Jules Olléon
    So far I've only build "small" graphical applications, using swing and JComponents as I learned at school. Yet I can't bear ugly JButtons anymore. I've tried to play with the different JButton methods, like changing colors, putting icons etc. but I'm still not satisfied. How do you make a nicer GUI in java ? I'm looking for not-too-heavy alternatives (like, without big frameworks or too complicated libraries).

  • How do I disable system pop-ups in Windows CE 6?

    - by Ben Schoepke
    What do I have to do to disable all system pop-ups in WinCE 6 R2? I read Mike Hall's post about Kiosk mode [1] but that's not going to work for us because we still want the standard graphical Explorer shell. We plan on hiding the taskbar and start menu and clearing icons off the desktop but need an easy way to make sure that no pop-ups of any type will ever show up on top of our app. Thanks, Ben http://blogs.msdn.com/mikehall/archive/2007/06/01/kiosk-mode-for-ce-6-0.aspx

  • The difference between triangulation and mesh

    - by xiao
    I have done some computer graphical programming recently, and I have no experience before. I used the library call CGAL(computer geometry algorithm library). Also, I noticed that there is class for triangulation and also class for mesh. Is mesh just a kind of triangle net? Do they have any differences? Thanks!

  • Static code analysis tools

    - by Anil Namde
    Whether JavaSript, C# or C++ main problem i face while reading the code is which function is called by which function. This problem is big when dealing with BIG code. Is there any static code analysis tool/technique/plugins using which a graphical representation of the code can be generated(something like below) so that reading/analyzing code becomes easy? .... --outerFuntion() ---innerFunction() ----innerFunction2() --outerFunction2() .... Please provide your inputs/opinions on this Thanks all,

  • Making a Game Without Graphics?

    - by cam
    Is it possible or even constructive to make a game without any graphics (but is intended to become graphical) I'm not good with graphics at all, so I'd like to write the skeleton for the game then have a graphics programmer/artist fill in the rest. I could write up all the major classes, and their interactions, and all the major functions/parts of the game. If so, what should I do to make it easier to integrate graphics into the game later on (every drawn object should have a Draw, Rotate, Collide, etc method) ?

  • Developing multiple user interfaces for an application

    - by denizkocak
    I want to develop an application which has a graphical user interface that could be developed by using different widget toolkits. For example I want to use Qt, GTK+ or even ncurses as a building block for my user interface for the same application. Moreover users could choose which GUI implementation will be used during the next startup of the application without recompiling it first. I wonder what are possible design strategies and design patterns used in the implementation of this design?

  • Difference between chart, plot and graph

    - by Pradyumna
    I'm thinking of what would be the right terms to use in the UI of my new program, when referring to graphical data representations - i.e., whether to call them "charts", "plots" or "graphs". I was wondering how these terms are different, and when is it appropriate to use each of them? Thanks, Pradyumna

  • Anyone know of a Java reporting tools which has a web based visual report designer?

    - by kwyjibo
    We're currently evaluating different Java reporting engines, and having a web-based ad-hoc report designer is a requirement. We don't need anything too fancy, but we need users to be able to define a report with columns X, grouped by Y, sorted by Z, etc... We've found that many of the open source tools do have graphical report designers, but the designers are typically not web based. (For example, iReport from JasperReports seems to be an application, not a web tool) Can anyone recommend a reporting tool which meets this web-based requirement?

  • Why enabling transparency can lead to cliping problems ?

    - by Amokrane
    Hi, I'm working on a 3D graphical application in Java using the Java 3D API. I noticed that every time I was dealing with transparency, all I got in return were some clipping problems. Some parts of the scene weren't displayed properly. It might seem obvious that this would happen in a certain way but I'm looking for a logical explanation, why is this happening? Thank you

  • Show or hide elements in PDF via Javascript

    - by Boldewyn
    In PDF files it is quite easy to interact with form fields via the Javascript API. Is it possible to do this (specifically showing/hiding) to arbitrary elements on a page? Say, not just form fields, but text, graphical elements, embedded images... Is there an API to interact with those? If yes, how do I identify an object?
