  • rhino embedding

    - by neheh
    Anyone understands the rhino javascript Contexts? I cannot find any useful documentation about it. My main problem is the Context.exit() (really should be cx.exit()) which from what I understand exits the context associated with the current thread? Does that mean I need to keep track of what which thread does? main thread: Context cx; cx.evaluateReader( ... ) // load some function start thread 2 thread 2: Object o= scope.get("methodname", scope); ((Function)o).call( ... ) I do not plan on doing multithreading but what if the different setups comes from different threads?

  • How to place text on top of image in ReportViewer

    - by Christoffer
    I feel very silly asking this, since it seems like it just should work, but I cannot make it work and cannot find anything in the documentation about this. The problem: I'm developing an application in Visual Studio 2010 that is utilizing ReportViewer, rendering the report locally. In the report designer, I place a textbox on top of an image. This looks fine in the designer, but when rendering the report, the textbox is rendered below the image. Now, before you suggest it, I have tried placing a textbox on top of a rectangle (or other control) with the BackgroundImage property set. This works. But: I cannot find a way to rescale the background image to fit the control. Setting a different dpi for the background image does nothing. Simply rescaling the image to a different resolution is not an option, since I eventually want to print the report. Does anybody have a solution to this?

  • Any form autofill for 'Developers'?

    - by Majid
    Hi all, I have looked at some autofills for Firefox. But they are not designed with the developers' needs in mind. General internet surfers will need a tool to fill in many different forms with constant values for each form. Developers need exactly the opposite, when you want to test a part of your app you'll need to fill a single (or a couple of) forms many times with different (but valid and sensible) data. So, does such a thing exist? An autofill to fill form inputs based on perhaps a class name (email, password, address, url, ...)? I strongly feel if it doesn't exist someone should roll up their sleeves and make one! I for one will put in my share if some others want to team up. But right now, I am desperately in need of one if it exists

  • What should I name my files with generic class definitions?

    - by Tomas Lycken
    I'm writing a couple of classes that all have generic type arguments, but I need to overload the classes because I need a different number of arguments in different scenarios. Basically, I have public class MyGenericClass<T> { ... } public class MyGenericClass<T, K> { ... } public class MyGenericClass<T, K, L> { ... } // it could go on forever, but it won't... I want them all in the same namespace, but in one source file per class. What should I name the files? Is there a best practice?

  • stuck on sliders with jquery

    - by chris
    I am building a portfolio page of different work that has been done and im using two different jquery sliding techniques, one nested in amongst the other one. The first slider works great but the second one doesnmt work that great for the first few and then doesnt work at all. If you take a look at this page- You can click the clients up and down the left side to slide the main divs, but when you click on the squares in below the images to slide in and out the content, either it doesnt work as smoothly as it should or it doesnt work right at all. http://justni.com/wip/mdd/martin_duggan_portfolio.html anyone wanna take a look at the code and tell me what am doing wrong?

  • What is the best Java numerical method package?

    - by Bob Cross
    I am looking for a Java-based numerical method package that provides functionality including: Solving systems of equations using different numerical analysis algorithms. Matrix methods (e.g., inversion). Spline approximations. Probability distributions and statistical methods. In this case, "best" is defined as a package with a mature and usable API, solid performance and numerical accuracy. Edit: derick van brought up a good point in that cost is a factor. I am heavily biased in favor of free packages but others may have a different emphasis.

  • abstract class MouseAdapter vs. interface

    - by Stefano Borini
    I noted this (it's a java.awt.event class). public abstract class MouseAdapter implements MouseListener, MouseWheelListener, MouseMotionListener { .... } Then you are clearly forced to extend from this adapter public class MouseAdapterImpl extends MouseAdapter {} the class is abstract and implements no methods. Is this a strategy to combine different interfaces into a single "basically interface" ? I assume in java it's not possible to combine different interfaces into a single one without using this approach. In other words, it's not possible to do something like this in java public interface MouseAdapterIface extends MouseListener, MouseWheelListener, MouseMotionListener { } and then eventually public class MouseAdapterImpl implements MouseAdapterIface {} Is my understanding of the point correct ? what about C# ?

  • Are concurrency issues possible when using the WCF Service Behavoir attribute set to ConcurrencyMode

    - by Brandon Linton
    We have a WCF service that makes a good deal of transactional NHibernate calls. Occasionally we were seeing SQL timeouts, even though the calls were updating different rows and the tables were set to row level locking. After digging into the logs, it looks like different threads were entering the same point in the code (our transaction using block), and an update was hanging on commit. It didn't make sense, though, because we believed that the following service class attribute was forcing a unique execution thread per service call: [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.PerCall)] We recently changed the concurrency mode to ConcurrencyMode.Single and haven't yet run into any issues, but the bug was very difficult to reproduce (if anyone has any thoughts on flushing a bug like that out, let me know!). Anyway, that all brings me to my question: shouldn't an InstanceContextMode of PerCall enforce thread-safety within the service, even if the ConcurrencyMode is set to multiple? How would it be possible for two calls to be serviced by the same service instance? Thanks!

  • How to successfully implement og:image for the LinkedIn

    - by Sabo
    THE PROBLEM: I am trying, without much success, to implement open graph image on site: http://www.guarenty-group.com/cz/ The homepage is completeply bypassing the og:image tag, where internal pages are reading all images from the site and place og:image as the last option. Other social networks are working fine on both internal pages and homepage. THE CONFIGURATION: I have no share buttons or alike, all I want is to be able to share the link via my profile. The image is well over 300x300px: http://guarenty-group.com/img/gg_seal.png Here is how my head tag looks like: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Guarenty Group : Pojištení pro nájemce a pronajímatelé</title> <meta name="keywords" content="" /> <meta name="description" content="Guarenty Group pojištuje príjem z nájmu pronajímatelum, kauci nájemcum - aby nemuseli platit velkou cástku v hotovostí predem - a dále nájemcum pojištuje príjmy, aby meli na nájem pri nemoci, úrazu ci nezamestnání." /> <meta name="image_src" content="http://guarenty-group.com/img/gg_seal.png" /> <meta name="image_url" content="http://guarenty-group.com/img/gg_seal.png" /> <meta property="og:title" content="Pojištení pro nájemce a pronajímatelé" /> <meta property="og:url" content="http://guarenty-group.com/cz/" /> <meta property="og:image" content="http://guarenty-group.com/img/gg_seal.png" /> <meta property="og:description" content="Guarenty Group pojištuje príjem z nájmu pronajímatelum, kauci nájemcum - aby nemuseli platit velkou cástku v hotovostí predem - a dále nájemcum pojištuje príjmy, aby meli na nájem pri nemoci, úrazu ci nezamestnání [...]" /> ... </head> THE TESTING RESULTS: In order to trick the cache i have tested the site with http://www.guarenty-group.com/cz/?try=N, where I have changed the N every time. The strange thing is that images found for different value of N is different. Sometimes there is no image, sometimes there is 1, 2 or 3 images, but each time there is a different set of images. But, in any case I could not find the image specified in the og:graph! MY QUESTIONS: https://developer.linkedin.com/documents/setting-display-tags-shares is saying one thing, and the personnel on the support forum is saying "over 300" Does anyone know What is the official minimum dimension of the image (both w and h)? Can an image be too large? Should I use the xmlns, should I not use xmlns or it doesn't matter? What are the maximum (and minimum) lengths for og:title and og:description tags? Any other suggestion is of course welcomed :) Thanks in advance, cheers~

  • How do I join two git repos without a common root, where all modified files are the same?

    - by Evan Carroll
    I have a git-cpan-init of a repo which yielded a different root node from another already established git repo I found on github C:A:S:DBI. I've developed quite a bit on my repo, and I'd like to merge or replay my edits on a fork of the more authoritative repository. Does anyone know how to do this? I think it is safe to assume none of the file-contents of the modified files are different -- the code base hasn't been since Nov 08'. For clarity the git hub repo is the authoritative one. My local repo is the one I want to go up to git hub shown as a real git fork.

  • ASCII in Windows XP and Ubuntu Linux

    - by Mikey D
    I've made a program in MVSC++ which outputs memory contents (in ASCII). The ASCII I see in windows console seem to match what I see in various ASCII tables (smiley, diamond, club, right arrow etc). This program needs to compile under Linux (which is does), but the ASCII output looks completely different. A few symbols are the same but the rest are so different. Is there any way to change how terminal displays ASCII code? EDIT: The program executes correctly, it's just the ASCII that is being displayed differently.

  • Find valid assignments of integers in arrays (permutations with given order)

    - by evident
    Hi everybody! I am having a general problem finding a good algorithm for generating each possible assignment for some integers in different arrays. Lets say I have n arrays and m numbers (I can have more arrays than numbers, more numbers than arrays or as much arrays as numbers). As an example I have the numbers 1,2,3 and three arrays: { }, { }, { } Now I would like to find each of these solutions: {1,2,3}, { }, { } { }, {1,2,3}, { } { }, { }, {1,2,3} {1,2}, {3}, { } {1,2}, { }, {3} { }, {1,2}, {3} {1}, {2,3}, { } {1}, { }, {2,3} { }, {1}, {2,3} {1}, {2}, {3} So basically I would like to find each possible combination to assign the numbers to the different arrays with keeping the order. So as in the example the 1 always needs to come before the others and so on... I want to write an algorithm in C++/Qt to find all these valid combinations. Does anybody have an approach for me on how to handle this problem? How would I generate these permutations?

  • Conseqences of assigning self

    - by Vegar
    Hi, Found a piece of code today, that I find a little smelly... TMyObject.LoadFromFile(const filename: String); begin if fileExists(filename) then self := TSomeObjectStreamer.ReadObjectFromFile(filename); end; If this code works, it will atleast leak some memory, but does it work? Is OK to assign to self in this manner? What if the streamed object is of a different subclass then the original self? What if the streamed object is of a different class with no common ancestore to the original self?

  • 'Array of arrays' in matlab?

    - by waitinforatrain
    Hey, having a wee bit of trouble. Trying to assign a variable length 1d array to different values of an array, e.g. a(1) = [1, 0.13,0.52,0.3]; a(2) = [1, 0, .268]; However, I get the error: ??? In an assignment A(I) = B, the number of elements in B and I must be the same. Error in ==> lab2 at 15 a(1) = [1, 0.13,0.52,0.3]; I presume this means that it's expecting a scalar value instead of an array. Does anybody know how to assign the array to this value? I'd rather not define it directly as a 2d array as it is for are doing solutions to different problems in a loop Edit: Got it! a(1,1:4) = [1, 0.13,0.52,0.3]; a(2,1:3) = [1, 0, .268];

  • Asset tracking in "real-time" - how best to display in browser?

    - by mawg
    I am developing an asset tracking system, standard LAMP, and now am wondering how best to present the data to the user in the browser. I expect to track and most a few thousand items, and to refresh them every second or so. I want to draw a floorplan or map of the area and represent the assets the assets symbolically on that (with different symbols for different classes of assets). Additionally, the user should be able to click on an asset to interact with it, and search for a particular asset and centre the screen on it, draw a circle round it, etc http://graphite.wikidot.com/ Looks good - is there any alternative? At its simplest, I suppose I could just generate a JPEG and display it, using CSS to let me know if/where a user clicks ... but what's the "best" way to do it?

  • How should I use color in my application? Single, Theme, or Chaos?

    - by CodeSlave
    How should I be using color in my application? I have over a 100 different forms (windows) in my application, and the default windows grey seems like a bad choice to me. One school of thought says pick one neutral color, and use the same one everywhere. Another school of thought says pick a set of neutral colors, and use them same ones within a group of form (e.g., shipping screens might be light green, receiving screens light orange, user administration screens light blue, etc.). The final school of thought says make every form different. We've got millions of colors, why not use them? What should I do and why?

  • How to do 'git status' on untracked directory?

    - by meowsqueak
    I have 6,000 untracked files in one subdirectory and I'm constructing .gitignore files to filter out the unwanted ones. I'm testing my gitignore filters as I go by running 'git status'. However, I have a larger number of untracked other files in a different subdirectory, so 'git status' shows all of those too, which makes it very hard to see what the .gitignore rules are doing. If the files were tracked, then I could just do 'git status .' and it would restrict the git-status output to only those files in the current directory, but because the current directory and all its contents are untracked, 'git status .' returns "error: pathspec . did not match any file(s) known to git." I'm using git-1.6.6.1 for this, although interestingly my testing shows that git-1.7.1 (on a different system) does actually let you do git-status on an untracked directory. Unfortunately I can't upgrade git on this system. Is there a known workaround for -1.6.6.1?

  • How to detect the language of MS Excel from C#

    If i try to use Excel from C# (interop) i receive error (HRESULT: 0x80028018) when current thread language is different from Excel language: so i need to set thread language, they must be the same. Which is the best method to understand the language of Excel/Office? 1) registry (HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\LanguageResources\UILanguage ?

  • Many to Many DataSet Insert to Database using Stored Procedures

    - by Jonn
    I'm trying to do a many-to-many bulk insert to the database using a list of three different types of models. The only tools I can use are stored procedures and datasets. (But I can't use DataSet fills or DataAdapters, just plain ol' Stored Procedures). Is there an easy way to pass multiple values, let alone, pass three different lists and bulk insert them to a table in the database using stored procedures? (As specified in the title, the three tables are actually two tables and a third table to establish the many-to-many relationship between the two.)

  • What should be the image resolution for Nexus One or Droid?

    - by sunil
    Hi, As Android supports multiple devices from different manufacturers there are different screen resolutions supported. The table that is available at http://developer.android.com/intl/fr/guide/practices/screens_support.... is not very clear to me. It shows WVGA and FWVGA in MDPI for Large Screens and HDPI for Normal screens. So, if the image is kept in drawable-mdpi and its resolution is 320 * 480 then which image will be taken by Large Screens device of MDPI. Moreover, there are two screen resolutions for HDPI i.e. 480 * 800 and 480 * 854. So, with what screen resolution the image should be built. I want to place the background image which looks distorted in WVGA emulator since its resolution is 320 * 480. I have read about nine patchable images but I think they are better for button images and edittext images so that they can stretch according to the data in it. Can someone please guide me in this? Regards Sunil

  • Why Date Format in ASP NET MVC Differs when used inside Html Helper?

    - by Marcio Gabe
    Hi, I just came across a very interesting issue. If I use ViewData to pass a DateTime value to the view and then display it inside a textbox, even though I'm using String.Format in the exact same manner, I get different formatting results when using the Html.TextBox helper. <%= Html.TextBox("datefilter", String.Format("{0:d}", ViewData["datefilter"]))%> <input id="test" name="test" type="text" value="<%: String.Format("{0:d}", ViewData["datefilter"]) %>" /> The above code renders the following html: <input id="datefilter" name="datefilter" type="text" value="2010-06-18" /> <input id="test" name="test" type="text" value="18/06/2010" /> Notice how the fist line that uses the Html helper produces the date format in one way while the second one produces a very different output. Any ideas why? Note: I'm currently in Brazil, so the standard short date format here is dd/MM/yyyy.

  • What is the difference between MVC model 1 and model 2?

    - by Alex Ciminian
    I've recently discovered that MVC is supposed to have two different flavors, model one and model two. I'm supposed to give a presentation on MVC1 and I was instructed that "it's not the web based version, that is refered to as MVC2". As the presentations are about design patterns in general, I doubt that this separation is related to Java (I found some info on Sun's site, but it seemed far off) or ASP. I have a pretty good understanding of what MVC is and I've used several (web) frameworks that enforce it, but this terminology is new to me. How is the web-based version different from other MVC (I'm guessing GUI) implementations? Does it have something to do with the stateless nature of HTTP? Thanks, Alex

  • How to leverage Spring Integration in a real-world JMS distributed architecture?

    - by ngeek
    For the following scenario I am looking for your advices and tips on best practices: In a distributed (mainly Java-based) system with: many (different) client applications (web-app, command-line tools, REST API) a central JMS message broker (currently in favor of using ActiveMQ) multiple stand-alone processing nodes (running on multiple remote machines, computing expensive operations of different types as specified by the JMS message payload) How would one best apply the JMS support provided by the Spring Integration framework to decouple the clients from the worker nodes? When reading through the reference documentation and some very first experiments it looks like the configuration of an JMS inbound adapter inherently require to use a subscriber, which in a decoupled scenario does not exist. Small side note: communication should happen via JMS text messages (using a JSON data structure for future extensibility).
