  • Problem with dojo tree

    - by Ewout
    Hello, I'm trying to get the dojo tree widget working. It works with a small json object, but when i try it with a large json object it goes wrong. There is no error, just the root node. Is this a normal behavior? Is there a maximum of objects you can load? My json object contains around 800 entries. Thanks, Ewout

  • dlopen and global variables in C/C++

    - by mjn12
    Due to some restrictions I am being forced to load a library written in C at runtime. A third party provides two library to me as static archives which we turn into shared objects. The application I'm working with loads one of the libraries at runtime based on some hardware parameters. Unfortunately one of the libraries is configured largely with global variables. I am already using dlsym to load function references but can I used dlsym to load references to these global variables as well?

  • Using Predicate of a class to Search Generic list - Faster than looping?

    - by Srikanth
    Lets say we have a generic list of Class1, typically having ~100 objects for a given session. I would like to see if the list has a particular object. ASP.NET 2.0 allows me to do this: Dim objResult as Class1 = objList.Find(objSearch) How does this approach rate when compared to a traditional For loop, looking at a performance perspective? How would this vary with increase or decrease in length of the list?

  • Adding object to child collection causes entire collection to load in Fluent NHibernate.

    - by Mike C.
    Hello, I have my Parent object, which contains an ICollection of Children objects. The Children are lazy loaded and I do not need them in the context of my scenario. However, when I try to add a new child object to my Children collection, it kicks off the lazy load and loads all 7000 child records. I assume I am making a newbie mistake. Anybody out there know how I can fix this? Thanks!

  • Are there java libraries to do a word-based diff?

    - by Mycol
    I have two pieces of text. I would like to make a word-based diff between them (like whe unix utility wdiff does) but with more information in the output (I mean, the character's posizion where the added/delited word starts). I need to do this in Java, so a simple output of the differences (like wdiff) doesn't suite for me: I would like to manipulate objects representing differences.

  • How to integrate camera image into physics engine?

    - by Pedro
    I recently came across this and would like to implement something similar. The basic approach is clear: I have to threshold the image and check if a virtual object collides with the remaining foreground. Instead of implementing the physics myself, I'd like use an engine like Box2D. But how do I integrate the thresholded image into the physics engine so it is possible to interact with virtual objects?

  • What library should I use for financial product pricing?

    - by watkins
    I work in software division of a large bank and we are considering writing our own financial library. However, before we embark in such a project, I want to check that there is no such library on the market. We would need to have the following feature: Pricing of derivative products (options, futures, swaps, etc) Different financial models Hedging / risk management Open source would be great if it's stable. Otherwise, we would purchase the source code. We are looking for C#/.NET.

  • Why does obj.getBounds().height give a larger height than obj.height?

    - by TC
    I'm new to Flash and ActionScript, but managing quite nicely. One thing that is continuously getting in my way are the width and height properties of DisplayObject(Container)s. I'm finally starting to get my head around them and learned that the width and height of a Sprite are determined solely by their contents for example. I do not understand the following though: I've got a Sprite that I add a bunch of Buttons to. The buttons all have a height of 30 and an y of 0. As such, I'd expect the height of the containing Sprite to be 30. Surprisingly, the height is 100. The Adobe documentation of the height property of a DisplayObject states: Indicates the height of the display object, in pixels. The height is calculated based on the bounds of the content of the display object. Apparently, the 'bounds' of the object are important. So I went ahead and wrote this little test in the Sprite that contains the Buttons: for (var i:int = 0; i < numChildren; ++i) { trace("Y: " + getChildAt(i).y + " H: " + getChildAt(i).height); trace("BOUNDS H: " + getChildAt(i).getBounds(this).height); } trace("SCALEY: " + scaleY + " TOTAL HEIGHT: " + height); This code iterates through all the objects that are added to its display list and shows their y, height and getBounds().height values. Surprisingly, the output is: Y: 0 H: 30 BOUNDS H: 100 ... (5x) SCALEY: 1 TOTAL HEIGHT: 100 This shows that the bounds of the buttons are actually larger than their height (and the height that they appear to be, visually). I have no clue why this is the case however. So my questions are: Why are the bounds of my buttons larger than their height? How can I set the bounds of my buttons so that my Sprite isn't larger than I'd expect it to be based on the position and size of the objects it contains? By the way, the buttons are created as follows: var control:Button = new Button(); control.setSize(90, 30); addChild(control);

  • What is the efficient way to find some pattern in a big text?

    - by salman
    I want to extract email addresses from a large text file. what is the best way to do it? My idea is to find '@' in the text and use "Regex" to find email address into substring at (for example) 256 chars before this position and length of 512. P.S.: Straightforwardly I want to know the best and most efficient way to find some pattern (like email addresses) in a huge text.

  • Quicktime logo! Can it be hidden / disabled?

    - by decbrad
    Hi there, just wondering if it is possible to hide/disable the quicktime logo when displaying .MOV video on my site? Because the size of the video is large (3MB), I have included a rotating loading animation, however once the video player loads, the Quicktime logo hides the animation, which makes the user less likely in my opinion to wait for the movie to load? Any advice would be great! Cheers! Decbrad

  • How can I avoid huge communication classes in WCF?

    - by mafutrct
    My understanding is that all contract-implementing code has to be in a single class, that can become very large, obviously. How do I avoid this? I really prefer to have a few small classes doing one part of the communication with clients than a single behemoth class. The only idea I could think of is using multiple interfaces implemented by a single class split up by partial, but I don't this this is really solving the issue.

  • Best Java thread-safe locking mechanism for collections?

    - by Simon
    What would be the least-slow thread-safe mechanism for controlling multiple accesses to a collection in Java? I am adding objects to the top of a collection and i am very unsure what would be the best performing collection. Would it be a vector or a queue? I originally thought an ArrayList would be fast but i ran some experiments and it was very slow. EDIT: In my insertion testing a Vector delared using volatile seems to be the fastest?

  • Counting number of values between interval

    - by calccrypto
    Is there any efficient way in python to count the times an array of numbers is between certain intervals? the number of intervals i will be using may get quite large like: mylist = [4,4,1,18,2,15,6,14,2,16,2,17,12,3,12,4,15,5,17] some function(mylist, startpoints): # startpoints = [0,10,20] count values in range [0,9] count values in range [10-19] output = [9,10]

  • What are the standard practices for throwing JavasScript Exceptions?

    - by T.R.
    w3schools says that exceptions can be strings, integers, booleans, or objects, but the example given doesn't strike me as good practice, since exception type checking is done through string comparison. Is this the preferred method of exception handling in JavaScript? Are there built-in exception types (like NullPointerException)? (if so, what are they, what kind of inheritance do they use, and are they preferred over other options?)

  • What's -mutableSetValueForKey: returning, actually? Is that something special?

    - by dontWatchMyProfile
    From the docs: You usually access to-many relationships using mutableSetValueForKey:, which returns a proxy object that both mutates the relationship and sends appropriate key-value observing notifications for you. So this returns an "intelligent" NSMutableSet which automatically lets the context delete objects when they get deleted from the set, and reverse? Is that a proxy object?
