  • Rewriting a simple Pygame 2D drawing function in C++

    - by Dominic Bou-Samra
    I have a 2D list of vectors (say 20x20 / 400 points) and I am drawing these points on a screen like so: for row in grid: for point in row: pygame.draw.circle(window, white, (particle.x, particle.y), 2, 0) pygame.display.flip() #redraw the screen This works perfectly, however it's much slower then I expected. I want to rewrite this in C++ and hopefully learn some stuff (I am doing a unit on C++ atm, so it'll help) on the way. What's the easiest way to approach this? I have looked at Direct X, and have so far followed a bunch of tutorials and have drawn some rudimentary triangles. However I can't find a simple (draw point).

  • How I May Have Taken A Wrong Path in Programming

    - by Ygam
    I am in a major stump right now. I am a BSIT graduate, but I only started actual programming less than a year ago. I observed that I have the following attitude in programming: I tend to be more of a purist, scorning unelegant approaches to solving problems using code I tend to look at anything in a large scale, planning everything before I start coding, either in simple flowcharts or complex UML charts I have a really strong impulse on refactoring my code, even if I miss deadlines or prolong development times I am obsessed with good directory structures, file naming conventions, class, method, and variable naming conventions I tend to always want to study something new, even, as I said, at the cost of missing deadlines I tend to see software development as something to engineer, to architect; that is, seeing how things relate to each other and how blocks of code can interact (I am a huge fan of loose coupling) i.e the OOP thinking I tend to combine OOP and procedural coding whenever I see fit I want my code to execute fast (thus the elegant approaches and refactoring) This bothers me because I see my colleagues doing much better the other way around (aside from the fact that they started programming since our first year in college). By the other way around I mean, they fire up coding, gets the job done much faster because they don't have to really look at how clean their codes are or how elegant their algorithms are, they don't bother with OOP however big their projects are, they mostly use web APIs, piece them together and voila! Working code! CLients are happy, they get paid fast, at the expense of a really unmaintainable or hard-to-read code that lacks structure and conventions, or slow executions of certain actions (which the common reasoning against would be that internet connections are much faster these days, hardware is more powerful). The excuse I often receive is clients don't care about how you write the code, but they do care about how long you deliver it. If it works then all is good. Now, did my "purist" approach to programming may have been the wrong way to start programming? Should I just dump these purist concepts and just code the hell up because I have seen it: clients don't really care how beautifully coded it is?

  • Set asisde space for ADT when reading integers from file

    - by That Guy
    I'm using C to make maze solver. The program should be able read a maze from a text file containing a grid of 1 and 0 representing walls and paths. This file could be of any size as the user selects which maze to use. The program should then show the maze being solved. As the maze is being solved it should show where has been walked and how many steps have been taken. I have made an ADT called Cell containing a bool for wall or path and an integer for steps taken. I now need to populate a 2D array of Cells which means I need to set aside enough space to store a Cell for every integer in the maze file. What would be the best way to do this?

  • How to save the world from your computer?

    - by Francisco Garcia
    Sometimes I miss the "help other people" factor within computer related careers. Sure that out there I could find many great projects improving society, but that is not common. However there are little things that we all can do to make this a better place beyond trying to erradicate annoynig stuff such as Visual Basic. You could join a cloud computing network such as World Community Grid to fight cancer. Write a charityware application such as Vim, improve an office IT infrastructure to support telecommuting and reduce CO2 emissions, use an ebook reader for saving paper... what else would you? which projects do you think can have an impact?

  • Embeddable unit testing framework for mixed Windows app

    - by Andy Dent
    I want to test portions of a very complex app which includes both a major native Windows component and a substantial WPF GUI. Due to complexities I can't detail, it is impossible to run the native portion independently nor can I isolate the areas I want to test (spare me the lectures, we're talking a huge legacy code base and we do have refactoring plans). I'm looking for a unit test kit I can invoke on the native side but must be able to run with the app launched with the managed portion initialised. That seems to rule out the run executable feature of the cfix Windows unit test kit. I really like their philosophy, like WinUnit, of using DLL compilation as a way to add the reflective capabilities missing in C++ and gain a more NUnit-like experience. Ideally, I want something like WinUnit running within the application code and generating an HTML report. I'm trying to introduce more TDD and having things as lean as possible is important.

  • ArgumentException was unhandled Application.run

    - by user369758
    Hi I've been through many sites and can't seem to find an answer. I modified a view that was connected to a Datagridview connected through a tableadapter on a C# Winforms app and in order to "reconnect" I had to delete the tableadapter and reconnect it. This was to get rid of an error regarding Unique contstraints. So I fixed that and now the application launches but when I click on the tab that that grid is on I get: System.ArgumentException was unhandled Message="Cannot bind to the property or column Id on the DataSource.\r\nParameter name: dataMember" Source="System.Windows.Forms" ParamName="dataMember" StackTrace: at System.Windows.Forms.BindToObject.CheckBinding() at System.Windows.Forms.BindToObject.SetBindingManagerBase(BindingManagerBase lManager)......... I can't seem to find an answer to this problem. Can someone help me? Thanks

  • Project Euler #163 understanding

    - by Paul
    I spent quite a long time searching for a solution to this problem. I drew tons of cross-hatched triangles, counted the triangles in simple cases, and searched for some sort of pattern. Unfortunately, I hit the wall. I'm pretty sure my programming/math skills did not meet the prereq for this problem. So I found a solution online in order to gain access to the forums. I didn't understand most of the methods at all, and some just seemed too complicated. Can anyone give me an understanding of this problem? One of the methods, found here: http://www.math.uni-bielefeld.de/~sillke/SEQUENCES/grid-triangles (Problem C) allowed for a single function to be used. How did they come up with that solution? At this point, I'd really just like to understand some of the concepts behind this interesting problem. I know looking up the solution was not part of the Euler spirit, but I'm fairly sure I would not have solved this problem anyhow.

  • Setting focus on top of the page on click of asp.net link button

  • Tkinter mouse event initially triggered

    - by user3714884
    I'm currently learning Tkinter and I cannot find a solution for my problem here nor outside Stackoverflow. In a nutshell, all events that I bind to my widgets are triggered initialy and don't respond to my actions. In this example, the red rectangle appears on the canvas when I run the code, and color=random.choice(['red', 'blue']) revealed that the event binding doesn't work after that: import Tkinter as tk class application(tk.Frame): def __init__(self, master=None): tk.Frame.__init__(self, master) self.can = tk.Canvas(master, width=200, height=200) self.can.bind('<Button-2>', self.draw()) self.can.grid() def draw(self): self.can.create_rectangle(50, 50, 100, 100, fill='red') app = application() app.mainloop() I use a Mac platform, but I haven't got a clue about its role in the problem. Could anyone please point me at the mistake i did here?

  • Will .NET 4.0 apps work on Win 2008 R2 Server Core?

    - by markus
    When Windows Server 2008 R2 was launched, the "server core" edition started to become useful to me, because it lets me deploy .NET background applications isolated on their own virtual machine instance with only a small fraction of all the disk space overhead of a default Windows Server installation, and very few Windows Updates. It comes with a subset of .NET 3.5 SP1 integrated (as an optional feature). Now that .NET 4.0 is released, the redistributables explicitly state that it's not support on Server Core. Any chance that there will be a separate download available for Server Core (e. g. without WPF) any time soon, has anybody heard about it?

  • General approach for posting business logic status messages to UI?

    - by generalt
    Hello all. I have been struggling with this question for awhile now, and I haven't reached a conclusion. I'm not typically a UI programmer, so forgive the noobishness. I'm writing a typical application with a UI layer (WPF) and a business layer. I want to post status messages to the UI from the business layer (perhaps deep within the business layer), but I don't want the business layer to have any knowledge of the UI. Is there a generally accepted pattern for this? I was thinking to have a message queue of some sort to which the business layer posts status messages, and have the view model of the UI subscribe to that queue and intercept messages from the queue and route them to the UI. Is that a good approach? Is there somewhere else I should start? Thank you.

  • Ruby on Rails controller and architecture with cells

    - by dt
    I decided to try to use the cells plugin from rails: http://cells.rubyforge.org/community.html given that I'm new to Ruby and very used to thinking in terms of components. Since I'm developing the app piecemeal and then putting it together piece by piece, it makes sense to think in terms of components. So, I've been able to get cells working properly inside a single view, which calls a partial. Now, what I would like to be able to do (however, maybe my instincts need to be redirected to be more "Rails-y"), is call a single cell controller and use the parameters to render one output vs. another. Basically, if there were a controller like: def index params[:responsetype] end def processListResponse end def processSearchResponse end And I have two different controller methods that I want to respond to based on the params response type, where I have a single template on the front end and want the inner "component" to render differently depending on what type of request is made. That allows me to reuse the same front-end code. I suppose I could do this with an ajax call instead and just have it rerender the component on the front end, but it would be nice to have the option to do it either way and to understand how to architect Rails a bit better in the process. It seems like there should be a "render" option from within the cells framework to render to a certain controller or view, but it's not working like I expect and I don't know if I'm even in the ballpark. Thanks!

  • Books/resources on authentication and authorization in layered applications

    - by Tommy Jakobsen
    I've been trying to find resources and guidelines for implementing authentication and authorization in multiple layered architectures (C#), but haven't found any "best practices" or patterns to use. And I figured, that there must be some patterns for this, as it is a pretty important area? The application that we're developing, is layered traditionally, having data layer (Entity Framework 4) repositories domain layer service layer (can be WCF, with data transfer objects) multiple clients consuming the WCF service (ASP.NET [MVC], Silverlight, WPF) and clients accessing a service layer directly (no WCF) Are there books/articles/blogs that dig deeply into this area? Primarily about authorization such as handling multiple roles and attributes attached to users). It doesn’t have to be specific for the .NET Framework, but it would be preferred.

  • Which is the UI technology of the future considering: eye-candy-effect, interactivity (gestures, voc

    - by user193655
    If you had to write a next-gen application, in which on the surface (UI) you need some "futuristic features", by considering the following aspects which is the choice you'd make? 1) eye-candy: cool UI, 3D, Effects, nice graphics, sound transitions... 2) user interaction: not only mouse and keyboard but touch, voice and more.... + user interactivity aspect, which is the technology you'd choose? 3) X-platform: this is to have some X-platform discussion. Of course single platform technologies (as WPF) have may be some more power, anyway in a general discussion considering X-platform as a resource is important 4) available components: of course the coolest technology with no available components is may be an option for a component developer but not for an application developer My question is generic, but anyway * have in mind data-driven apps, not pure multimedia apps, videogames, ....

  • Is there a way to validate the presence of Javadoc and/or inline code comments?

    - by Chris Aldrich
    We are trying to put quality code processes in place for a large project I am working on. Right now a lot of developers are not putting in Javadoc or in-line code comments into their code. Ok right now. But it will severely hurt us in the very near future. We are using Maven 2.0.9 as our build tool, as well as Hudson for Continuous Integration. We are using Subversion as our source versioning tool/code repository, Rational Application Developer and Rational Softare Architect (essentially Eclipse) 7.5.1 as our IDE's, and then Subclipse as our Eclipse plug-in to connect to SVN. Is there a plug-in or a way to validate that a developer put in Javadoc and/or in-line code comments in order to allow a commit to SVN? This isn't intended to be a substitute for good code reviews, but merely a help to make sure that developers are reminded to add this documentation before committing. We are still intending on conducting code reviews that would also review documentation. Has anyone found any plug-ins for something like this? Any links? Any ideas?

  • Switching layouts page jumping (improvement to script)

    - by Ricardo Zea
    Hello, I'm using this script to switch layouts in a page: $("span.switcher").click(function () { $("span.switcher").toggleClass("swap"); /*!*/ $("ol.search-results").fadeOut("fast", function() { $(this).fadeIn("fast").toggleClass("grid"); }); The script works fine, the problem I have is that if the switch view is down the page, the layout changes and then the page jumps back up. If I add 'return false' right where you see the /* ! */ in the second line the script doesn't work. Also, as you can see, I'm using < span instead of < a since I was told that using other element other than < a would stop the page from jumping. Any idea how to fix the jumping of the page? Thanks.

  • UML diagrams that are actually pretty?

    - by Borek
    I'm looking for a diagramming software that would produce good looking output. It doesn't need to support everything (or even much) from UML, is doesn't need to have code engineering functions or anything, it just needs to produce visually interesting output. Here is a couple of samples of products that I consider ugly / not good enough: Visio with default UML stencils (didn't find better looking ones), Enterprise Architect, Dia, ArgoUML and many other "professional" UML tools. A couple of visually compelling tools that I considered (but found issues with): Visual Studio class diagrams - just for .NET classes but the output is miles better than what UML tools typically produce NClass - similar to VS's class diagrams but I could not find the "pretty", blue skin anywhere yuml.me - very nice but lacking some advanced layout options. I have to say that I find their style almost ideal for high-level diagrams - they look sketchy which is good. Balsamiq - I think Joel used this for hginit.com and I liked it. However, it's not suited for creating software diagrams so I can imagine it would be quite a lot of work MS Word has actually quite a good graphics engine but I'd rather leave this as a choice of the last resort I'd be grateful for any good tips.

  • How can I find out how many rows of a matrix satisfy a rather complicated criterion (in R)?

    - by Brani
    As an example, here is a way to get a matrix of all possible outcomes of rolling 4 (fair) dice. z <- as.matrix(expand.grid(c(1:6),c(1:6),c(1:6),c(1:6))) As you may already have understood, I'm trying to work out a question that was closed, though, in my opinion, it's a challenging one. I used counting techniques to solve it (I mean by hand) and I finaly arrived to a number of outcomes, with a sum of subset being 5, equal to 1083 out of 1296. That result is consistent with the answers provided to that question, before it was closed. I was wondering how could that subset of outcomes (say z1, where dim(z1) = [1083,4] ) be generated using R. Do you have any ideas? Thank you.

  • Small, editable table of strings. Which Forms control do I want? (.NET)

    - by I. J. Kennedy
    I have a small array of structs, each struct has three fields, all strings. I want to display these structs in a grid, let the user edit the strings a la Excel, and then retrieve the edited strings of course. Which WinForms control is best for this? Tried a DataGridView but setting the DataSource to the array of structs doesn't seem to work. There are myriad controls with similar names but I can't figure out what does what. All the examples I've found are geared toward using a database as the data source--I just have a simple array.
