  • In flex how do I pass data retrieved from a remote object service to a modules interface?

    - by Dan G
    I found at this Adobe tutorial a nice "RemoteService" class that creates a RemoteObject and contains the functions for handling the result and fault events. If I wanted to use this approach, how could I pass the data from the result handler to interfaces that modules from the main application could use? I could put the RemoteService/RemoteObject in the modules, but (in my opinion- and I could be wrong) the best design seems to be using the remote calls in the main app and passing the data along to the modules.

  • Functional programming approach for Java's input/output streams

    - by Elazar Leibovich
    I'm using Java's DataInputStream with scala to parse some simple binary file (which is very bad exprerience due to the lack of unsigned types, even in scala, but that's a different story). However I find myself forced to use mutable data structure, since Java's streams are inherently state preserving entities. What's a good design to wrap Java's streams with nice functional data structure?

  • Image compatibility in iphone and android

    - by damodar
    I developed UI for iphone apps and now want to use the same UI in Android apps. I read that Android use dip for image resolution and i also read that 1 dip=1.5 pixel.I simply multiply the image size by 1.5px. Now the problem is that the image is blur and not as clear as in iphone apps.So will some body suggest me how should i make a design so that it could be used in iphone and android.

  • Disposing the members that implement IDisposable.

    - by Amby
    In my Dispose methods (like the one below), everytime i want to call someObj.Dispose() i also have a check for someObj!=null. Is that because of bad design on my part? Is their a cleaner way to ascertain that Dispose of all the members (implementing IDisposable) being used in an object is called without having a risk of NullReference exception ? protected void Dispose(bool disposing) { if (disposing) { if (_splitTradePopupManager != null) { _splitTradePopupManager.Dispose(); } } } Thanks for your interest.

  • weighted RNG speed problem in C++

    - by supert
    I have a (fast) bit of C++ code that samples cards from a 52 card deck: void sample_allcards(int table[5], int holes[], int players) { int temp[5 + 2 * players]; bool try_again; int c, n, i; for (i = 0; i < 5 + 2 * players; i++) { try_again = true; while (try_again == true) { try_again = false; c = fast_rand52(); // reject collisions for (n = 0; n < i + 1; n++) { try_again = (temp[n] == c) || try_again; } temp[i] = c; } } copy_cards(table, temp, 5); copy_cards(holes, temp + 5, 2 * players); } I am implementing code to sample the hole cards according to a known distribution (stored as a 2d table). My code for this looks like: void sample_allcards_weighted(double weights[][HOLE_CARDS], int table[5], int holes[], int players) { // weights are distribution over hole cards int temp[5 + 2 * players]; int n, i; // table cards for (i = 0; i < 5; i++) { bool try_again = true; while (try_again == true) { try_again = false; int c = fast_rand52(); // reject collisions for (n = 0; n < i + 1; n++) { try_again = (temp[n] == c) || try_again; } temp[i] = c; } } for (int player = 0; player < players; player++) { // hole cards according to distribution i = 5 + 2 * player; bool try_again = true; while (try_again == true) { try_again = false; // weighted-sample c1 and c2 at once double w[1326]; memcpy(w, weights[player], sizeof(w)); // h is a number < 1325 int h = weighted_randi(w, HOLE_CARDS); // i2h uses h and sets temp[i] to the 2 cards implied by h i2h(&temp[i], h); // reject collisions for (n = 0; n < i; n++) { try_again = (temp[n] == temp[i]) || (temp[n] == temp[i+1]) || try_again; } } } copy_cards(table, temp, 5); copy_cards(holes, temp + 5, 2 * players); } My problem? The weighted sampling algorithm is a factor of 10 slower. Speed is very important for my application. Is there a way to improve the speed of my algorithm to something more reasonable? Am I doing something wrong in my implementation? Thanks.

  • SWT: cleaning up before application exit

    - by Alexey Romanov
    What is the best way for an SWT application to clean up resources before application exit? I see two options: 1) Add a DisposeListener to main window (or better, to the Display). Will it get run if an uncaught exception happens? 2) Use a shutdown hook. Any problems to be aware of there which aren't mentioned in Design of the Shutdown Hooks API?

  • Grading your programming ability?

    - by Farstucker
    I understand this is a subjective question and very likely could be closed, and although there is no right or wrong answer I do believe its a legitimate question. At what point do you no longer consider someone a beginner (ie knowledge of loops, encapsulation, instantiation), an intermediate (design patterns, reflection, delegates, interfaces) or an expert (architecture, multi-threadding). My rational for asking such a question is two-fold, first, when do I stop labeling my questions as beginner and during a job interview how should I categorize myself?

  • The use of Javascript - stats?

    - by Luke
    I am looking at redesigning my website and was wondering if I could get some opinions. I know that the rule is usually to design with users without JS first and foremost, but having looked at the stats, it appears 95% of the users online have JS enabled. Would you recommend designing the website using JS and not bothering about people without it?

  • How to prevent arbitrary code execution vulnerability in our programs?

    - by Calmarius
    You always read in changelogs when your system or browser or any program updates that they fixed a bug that made possible that an attacker can execute any code in your computer with a forged website, or attacking your computer with carefully forged packets, etc... Because you read it so often that means any program can have similar vulnerabilites... What causes this? how to design our programs to prevent similar issues?

  • linux/shell: change a file's modify timestamp relatively?

    - by index
    My Canon camera produces files like IMG_1234.JPG and MVI_1234.AVI. It also timestamps those files. Unfortunately during a trip to another timezone several cameras were used, one of which did not have the correct time zone set - meta data mess.. Now I would like to correct this (not EXIF, the file's "modify" timestamp on disk). Proposed algorithm: 1 read file's modify date 2 add delta, i.e. hhmmss (preferred: change timezone) 3 write new timestamp Unless someone knows a tool or a combination of tools that do the trick directly, maybe one could simplify the calculation using epoch time (seconds since ..) and whip up a shell script. Any help appreciated!

  • Designing the iPhone interface in a nib or in code?

    - by Jacob Relkin
    I've been pondering over this question for a long time already. On the one hand, Interface Builder offers a really easy way to design the interface and wire the elements up with objects in code. On the other hand, in larger projects, Interface Builder becomes a hassle to maintain. Any suggestions would be greatly appreciated.

  • Adding a Menu Item for only one Perspective

    I'm trying to add a Menu Item to the Run Menu in Eclipse via a plugin. However, I only want this Item to appear when I'm in the "Report Design" perspective (this is for BIRT).

I'm not having any luck using either of the visibility or visibleWhen elements in the plugin.xml Any hints appreciated, Ro
