• using arrays to get best memory alignment and cache use, is it necessary?

  - by Alberto Toglia

  I'm all about performance these days cause I'm developing my first game engine. I'm no c++ expert but after some research I discovered the importance of the cache and the memory alignment. Basically what I found is that it is recommended to have memory well aligned specially if you need to access them together, for example in a loop. Now, In my project I'm doing my Game Object Manager, and I was thinking to have an array of GameObjects references. meaning I would have the actual memory of my objects one after the other. static const size_t MaxNumberGameObjects = 20; GameObject mGameObjects[MaxNumberGameObjects]; But, as I will be having a list of components per object -Component based design- (Mesh, RigidBody, Transformation, etc), will I be gaining something with the array at all? Anyway, I have seen some people just using a simple std::map for storing game objects. So what do you guys think? Am I better off using a pure component model?

• Quick to develop web app in Java

  - by Mike Q

  Hi all, I need to develop a basic web app very quickly (1 week) for a demo. My requirements are Java (I need to make use of existing Java libraries to access the relevant data) 2 screens One for static data view, maybe some search parameters Other for basic form entry No fancy AJAX required Ideally easy for a web designer to come in and tart it up as necessary, without having to rewrite everything My first stop was going to be to checkout Wicket as I've heard good things about it. I don't have the time right now to dive into anything heavy, which probably writes off JSF in my mind (I played with JSF1, steep learning curve which I've now slid back down). I'm happy to treat the result as throwaway so if there's a framework which starts of well but then doesn't scale up to bigger projects, that would be ok. Any suggestions appreciated on frameworks/approach.

• how to use a wav file in eclipse

  - by AlphaAndOmega

  I've been trying to add audio to a project I've been doing. I found some code on here for html that is also supposed to work with file but it keeps saying "Exception in thread "main" javax.sound.sampled.UnsupportedAudioFileException: could not get audio input stream from input file at javax.sound.sampled.AudioSystem.getAudioInputStream(Unknown Source) at LoopSound.main(LoopSound.java:15)" the code public class LoopSound { public static void main(String[] args) throws Throwable { File file = new File("c:\\Users\\rabidbun\\Pictures\\10177-m-001.wav"); Clip clip = AudioSystem.getClip(); // getAudioInputStream() also accepts a File or InputStream AudioInputStream wav = AudioSystem.getAudioInputStream( file ); clip.open(wav); // loop continuously clip.loop(-1000); SwingUtilities.invokeLater(new Runnable() { public void run() { // A GUI element to prevent the Clip's daemon Thread // from terminating at the end of the main() JOptionPane.showMessageDialog(null, "Close to exit!"); } }); } } What is wrong with the code?

• LINQ 2 SQL Insert Error

  - by Refracted Paladin

  I have the below LINQ method that I use to create the empty EmploymentPLan. After that I simply UPDATE. For some reason this works perfectly for myself but for my users they are getting the following error -- The target table 'dbo.tblEmploymentPrevocServices' of the DML statement cannot have any enabled triggers if the statement contains an OUTPUT clause without INTO clause. This application is a WinForm app that connects to a local SQL 2005 Express database. public static Guid InsertEmptyEmploymentPlan(int planID, string user) { using (var context = MatrixDataContext.Create()) { var empPlan = new tblEmploymentQuestionnaire { PlanID = planID, InsertDate = DateTime.Now, InsertUser = user, tblEmploymentJobDevelopmetService = new tblEmploymentJobDevelopmetService(), tblEmploymentPrevocService = new tblEmploymentPrevocService() }; context.tblEmploymentQuestionnaires.InsertOnSubmit(empPlan); context.SubmitChanges(); return empPlan.EmploymentQuestionnaireID; } }

• How to avoid the Windows (XP) Security Warning when launching a "DOS" command line within C#?

  - by Will Marcouiller

  This question is related to this initial question asked a little while ago. Now, that I have chosen the extracting tool, I'm iterating through a given in command line parameter directory and subdirectories to extract the compressed .zip files. private static void ExtractAll(DirectoryInfo _workingFolder) { if(_workingFolder == null) { Console.WriteLine("Répertoire inexistant."); return; } foreach (DirectoryInfo subFolder in _workingFolder.GetDirectories("*", SearchOption.AllDirectories)) foreach(FileInfo zippedFile in subFolder.GetFiles("*.zip", SearchOption.AllDirectories)) { if(zippedFile.Exists) { ProcessStartInfo task = new ProcessStartInfo(@".\Tools\7za.exe", string.Format("x {0}", zippedFile.FullName)); Process.Start(task); } } } But everytime I start a 7za process, the Windows Security Warning prompts. I would like to avoid such annoying behaviour, so here's my question: How to avoid the Windows (XP) Security Warning when launching a "DOS" command line within C#?

• How can I make a recursive version of my iterative method?

  - by user247679

  Greetings. I am trying to write a recursive function in Java that prints the numbers one through n. (n being the parameter that you send the function.) An iterative solution is pretty straightforward: public static void printNumbers(int n){ for(int i = 1; i <= n; i++){ System.out.println(i); i++; } As a novice programmer, I'm having troubles figuring out how a recursive version of this method would work. Any bright ideas? Thanks for reading my problem!

• Understanding c++ block of code

  - by kotoko

  I was given a c++ main and have to code it so it works. I am having some trouble understanding the code as I am a bit new to cpp. Here is the code int main(int argc, char *argv[]) { Class::setAtribute("string"); Class(Class::CONSTANT) << "starting up..."; } Some questions: How can the first line work with no variables? Is it static? The second line is really strange for me, what I can make out is a Constructor that takes in a class constante and then prints it out somehow? If someone could explain me this bit of code it would be great! Thanks in advance.

• Virtual PC (XPMode) - How to access Webserver on guest from host

  - by sannoble

  I have Windows XP running inside Windows 7 via Virtual PC (XPMode) and installed Zend Server CE on the virtual XP guest. The webserver is running and can be accessed on the guest, but I cannot access the webserver from the Win7 host. I configured a static IP address and subnet of 255.255.255.0 on the guest and can ping this IP from the guest but not from the host. The other way it works fine, i.e. I can ping the host from the guest. I can also access the internet from the virtual XP guest. I tried different Network Options in the VirtualPC settings, but nothing helps. Googling the topic I couldn't find anything helpful yet. Any idea, what I could try to access the webserver on the virtual XP guest from the Win7 host?

• Animate a e.Graphics.DrawLine with arrowhead

  - by Fer

  I need to "animate" an arrow. It can go in any direction (up, down, left, right and diagonals) and the arrowhead will be at the end. It needs to appear as if it is growing from orgin to the end. To make matters more complicated it has to be in a user control so it is possible to add to the controls collection in the forms and remove it to delete it from the screen, and its background is really transparent (no color.transparent) so i can't paint the background to "clear" the previous line. I have it static already (drawn from origin to end) but i can't animate it. I tried to add a timer in the user control but I fail to get a correct algorithm to calculate the intermediate ends of the line while it is growing. Any help would be appreciated. Thanks

• View is moved 3 pixels

  - by Jakub

  Hello, In my app I move the table view (in order to make the text fields visible when the keyboard appears). The view is looks following: This is the code I use for resizing the view and moving it up: static const NSUInteger navBarHeight = 44; CGRect appFrame = [[UIScreen mainScreen] applicationFrame]; tableView.frame = CGRectMake(0, navBarHeight, appFrame.size.width, appFrame.size.height-navBarHeight-216); //216 for the keyboard NSIndexPath *indPath = [self getIndexPathForTextField:textField]; //get the field the view should scroll to [tableView scrollToRowAtIndexPath:indPath atScrollPosition:UITableViewScrollPositionMiddle animated:YES]; The problem is that when the view is moved up it also moves 3 pixels into right direction (it is hard to see the difference in the screenshot, but it is visible when the animation is on and I measured the difference with PixelStick tool). Here it is how it looks after the move: My analysis shows that scrolling the table does not influence the move to the right. Any ideas what is wrong in the code above that makes the view move to the right?

• Do I have partial view/code behind in Flask?

  - by hbrlovehaku

  I'm migrating from C#.NET to Python/Flask. In .NET I have MasterPage, UserControl, PartialView each has its own code behind. e.g. I can save the check login functions in Login.ascx.cs and render the Login.ascx wherever I'd like to. If logged in, it shows the welcome message, else shows the login form. But in Flask I only found {% include 'login.html' %} which include the static html file. How can I implement this design in Flask?

• Use desktop widget to run corporate web application

  - by jonny

  So the question is simple: is it possible to set windows desktop to corporate application page (anybody remembers that active desktop thing?) and use it instead of browser (sic!). My thoughts: Windows 7: I can create giant full-screen widget that will show my page. Still have no idea if I will be able to navigate inside it though. Windows Vista: ???. I know there is still a side bar gadget that hosts a browser. Windows XP: create static html page with iframe pointing to corporate app home page. Problem: clicking links on page still opens default browser.

• SkinId and Dynamic Control

  - by Alex

  Hi! I have some control that I add dynamically to my page: public partial class _Default : Page { protected override void CreateChildControls() { base.CreateChildControls(); var testControl = new TestControl { SkinID = "TestSkin" }; Controls.Add(testControl); } } I have the following skin file for this control: <cc:TestControl runat="server" SkinID="TestSkin" TestProperty="LALALA" /> But TestProperty is null (if control is static all works): public class TestControl : LinkButton { public string TestProperty { get; set; } protected override void OnPreRender(EventArgs e) { if (String.IsNullOrEmpty(TestProperty)) { throw new ArgumentNullException("TestProperty"); } } } Any ideas about how to fix it?

• Remove successive 0th entries in args[] for a Java command line interface?

  - by Bill IV

  I recall seeing, somewhere, an example that stepped through String args[] by deleting the lowest numbered value(s) public static void main( String args[]) { while (args.length > 0 ) { // do something and obliterate elements from args[] } } Obviously, a variable tracking current position in args and compared to args.length will do it; or an ArrayList made from args[]'s contents, with argsAL.size(). Am I mis-remembering an ArrayList example? I know this is a borderline question, the likely answer is, "No, there isn't and there shouldn't be either!". Maybe I'm over-focused... Bill

• identify the input that is multiple of 11 and odd or even java

  - by Bolor Ch

  i am trying to write code to determine the nature of input using if statement only. The nature of input could be following: a multiple of 11 even or odd. For the code below, when I enter my input, it does not display the result as "input:NOT:ODD". Also how can I check multiple conditions with if statement? (else is not considered) import java.util.Scanner; public class test { public static void main( String args[] ) { Scanner input = new Scanner( System.in ); int x; int EO; int Mult; System.out.print ( "Enter value: " ); x = input.nextInt(); EO = x % 2; Mult = x % 11; if (EO > 0 && Mult > 0) { System.out.printf ("%d:NOT:ODD"); } } }

• How to create custom CSS "on the fly" based on account settings in a Django site?

  - by sdolan

  So I'm writing a Django based website that allows users select a color scheme through an administration interface. I already have middleware/context processors that links the current request (based on domain) to the account. My question is how to dynamically serve the CSS with the account's custom color scheme. I see two options: Add a CSS block to the base template that overrides the styles w/variables passed in through a context processors. Use a custom URL (e.g. "/static/dynamic/css//styles.css") that gets routed to a view that grabs all the necessary values and creates the css file. I'm content with either option, but was wondering if anyone else out there has dealt with similar problems and could give some insight as to "Best Practices".

• Passing object through WCF so that server receives client changes

  - by cvig

  I would like to set up a WCF service so that any changes a client makes to an object I send them are also reflected on the server side. For example, if Assembly A has the following... namespace AssemblyA { public class Person { public string FirstName { get; set; } public string LastName { get; set; } } [ServiceContract] public interface IServer { [OperationContract] Person GetPerson(); } } And Assembly B references Assembly A... using AssemblyA; namespace AssemblyB { class Program { static void Main(string[] args) { <snip> IServer server = factory.CreateChannel(); Person person = server.GetPerson(); person.FirstName = "Kilroy"; person.LastName = "WuzHere"; } } } What is the easiest/best way to make it so that the service's copy of the Person object also reflects the changes that the client makes? Is this even possible?

• Why does GetExportedValues<T>() no longer work after using the .net 4 final version of MEF?

  - by BigJason

  I have been developing a managed extensibility framework application for the last several months using the community preview. I have been using the GetExportedValues() method and the PartCreationPolicy(CreationPolicy.NonShared) to fake a class factory (since only the silverlight version supports a factory). This was working great until I upgraded the project to use .net 4.0. There is no error, it just doesn't work. So why did this code stop working? The code follows: The factory method: public static IEnumerable<DataActionBase> GetActionsFromDirectory(string PluginsFolder) { IEnumerable<DataActionBase> result = null; var catalog = new DirectoryCatalog(PluginsFolder); var container = new CompositionContainer(catalog: catalog); result = container.GetExportedValues<DataActionBase>(); return result; } Example Export Class: [Export(typeof(DataActionBase))] [PartCreationPolicy(CreationPolicy.NonShared)] public class AnAction : DataActionBase { .... }

• C# .NET 2.0 components

  - by Ervin

  How can I check what objects, tools, variables, anything... are used from .NET 2.0 in a C# application. How can I get a C# application run without .NET 2.0 ? UPDATE: sorry, I didn't clarify enought. Here's my situation: I have developed a pretty simple application in C#: embeded browser which displayes static webpages with an option of searching inside of these html pages. I'm using simple textbox, buttons components for this. The application will be distribuited for people wich have very old PCs, even with windows 95. I would like the app to be runable on it, or at least on win 98, without telling the people to install .NET 2.0, as the users don;t really have PC usage skills :) .

• No difference between nullable:true and nullable:false in Grails 1.3.6?

  I have a composite server control that does quiet a number of things; one of which is to display a ModalPopup OnClick of a dynamically generated HtmlAnchor control. I need to create this ModalPopupExtender control dynamically in my server control and trigger it from within. I have been able to create it and trigger it from a button created at design time but not at runtime.

• Which is the future of web development: HTML5 or Silverlight(or other RIA framework)?

  - by Morgan Cheng

  My colleagues have a heated debate on what is the future of web development. One side is supporting HTML5 and the other is supporting Silverlight. There is no conclusion of the debate yet. In my humble opinion as a programmer, HTML5 will not improve programming productivity, while Silverlight will. In my understanding, programmers still need to program in JavaScript to take advantage of HTML5. For Silverlight, we can use C# which is static-type language. A lot of coding defects can be found in compilation time. For HTML5, different browsers might still have different behavior even though there is spec. For Silverlight, generally what works in IE will work the same way in other browsers. Just my thoughts. Any idea on how to choose future direction of web development?

• Could someone explain __declspec(naked) please?

  - by Scott

  I'm looking into porting a script engine written for Windows to Linux; it's for Winamp's visualization platform AVS. I'm not sure if it's even possible at the moment. From what I can tell the code is taking the addresses of the C functions nseel_asm_atan and nseel_asm_atan_end and storing them inside a table that it can reference during code execution. I've looked at MS's documentation, but I'm unsure what __declspec(naked) really does. What is prolog and epilog code mentioned in the documentation? Is that related to Windows calling conventions? Is this portable? Know of any Linux-based examples using similar techniques? static double (*__atan)(double) = &atan; __declspec ( naked ) void nseel_asm_atan(void) { FUNC1_ENTER *__nextBlock = __atan(*parm_a); FUNC_LEAVE } __declspec ( naked ) void nseel_asm_atan_end(void) {}
