  • How to parse JSON to receive a Date object in JavaScript?

    - by Piotr Owsiak
    I have a following piece of JSON: \/Date(1293034567877)\/ which is a result of this .NET code: var obj = DateTime.Now; var serializer = new System.Web.Script.Serialization.JavaScriptSerializer(); serializer.Serialize(obj).Dump(); Now the problem I am facing is how to create a Date object from this in JavaScript. All I could find was incredible regex solution (many containing bugs). It is hard to believe there is no elegant solution as this is all in JavaScrip, I mean JavaScript code trying to read JSON (JavaScript Object Notation) which is supposed to be a JavaScript code and at this moment it turns out it's not cause JavaScript cannot do a good job here. I've also seen some eval solutions which I could not make to work (besides being pointed out as security threat). Is there really no way to do it in an elegant way? Similar question with no real answer: How to parse ASP.NET JSON Date format with GWT

  • How to stop Visual Studio from returning duplicates answers?

    - by Franck Mesirard
    In my team, we put all our projects (only 7 large ones) in the same solution. And since some code is common between project we tend to have the same file included in each project. This is fine and compiles/runs well. But when I do a global search in my solution, VS does a "stupid" search and goes through all the files in each project, without checking if a file has already been searched. This leads to longer searches whose results have duplicates. Do anyone know a fix for this issue?

  • Error in qsort function in Programming Pearls?

    - by Dervin Thunk
    Hello, is it just me or this code in Programming Pearls is wrong (quicksort wants 2 const voids, no?) If so, is my solution right? Apologies, just learning... int wordncmp(char *p, char* q) { int n = k; for ( ; *p == *q; p++, q++) if (*p == 0 && --n == 0) return 0; return *p - *q; } int sortcmp(char **p, char **q) { return wordncmp(*p, *q); } ... qsort(word, nword, sizeof(word[0]), sortcmp); Is this a solution? int sortcmp(const void *p, const void *q) { return wordncmp(* (char * const *) p, * (char * const *) q); }

  • Database for Importing NUnit results?

    - by McWafflestix
    I have a large set of NUnit tests; I need to import the results from a given run into a database, then characterize the set of results and present them to the users (email for test failures, web presentation for examining results). I need to be tracking multiple runs over time, as well (for reporting failure rates over time, etc.). The XML will be the XML generated by nunit-console. I would like to import the XML with a minimum of fuss into some database that can then be used to persist and present results. We will have a number of custom categories that we will need to be able to sort across, as well. Does anyone know of a database schema that can handle importing this type of data that can be customized to our individual needs? This type of problem seems like it should be common, and so a common solution should exist for it, but I can't seem to find one. If anyone has implemented such a solution before, advice would be appreciated as well.

  • Passing parameters into ViewModels (Prism)

    - by vXtreme
    Hi I can't figure out how to pass parameters to my viewmodels from other views or viewmodels. For instance, I have a View called Customers. There is a grid inside, and if you double-click the grid, a new view is supposed to come up and allow you to edit that customer's data. But how will the View(Model) responsible for editing data know which customer it's supposed to open if I can't pass any parameters inside? EventAggregator is out of the question because I obviously can't create hundreds of eventargs, each for one view. And besides, it's a lousy solution. So far I was able to come up with: CustomerDataView custView = new CustomerDataView(customerId, currentContext); manager.Regions[RegionNames.Sidebar].AddAndActivate(custView); What do you think about this particular solution? Is this the way it's normally done? What I don't like about this is the fact that I lose out on automatic dependency injection by Unity.

  • How can I organize many results in a selectbox using php?

    - by zeckdude
    I have a select box that is part of a form. It is currently querying the addresses table and displaying the addresses into the select box. I plan on having up to 100 addresses. I'm looking for a solution where I can show all the states if the user clicks on the select box. Then if the user hovers over a state it will show all the addresses for that specific state. Then if the user clicks on an address, it will show that as the picked option in the select box. This is like a dropdown menu within a select box. Does anyone know where I can find a solution as this?

  • What is recursion? -- In plain english.

    - by Christopher Altman
    I hear this word everyday, but cannot give a meaningful, concise, or plain-english answer to what it is. Recursion is defined by the bastian of knowledge as: Recursion in computer science is a method where the solution to a problem depends on solutions to smaller instances of the same problem.1 The approach can be applied to many types of problems, and is one of the central ideas of computer science.[2] Source Is recursion simply something that repeats itself to get a solution? I am looking for a "Recursion for Dummies" definition, and maybe simple examples. My goal is to be able to understand and explain recursion in my own words. I do not like simply thinking I know the meaning of something because I hear it referenced daily, but have not paused to form my own understanding.

  • IE7 ignoring margin in a div following an absolute positioned div

    - by 0al0
    I have two divs inside a container, the first one has absolute positioning. In ie7, the second div apparently ignores the top margin. Padding seems to work fine, but for visual reasons I have to use margin. I know the culprit is the absolute positioned div because if i remove it the following div works fine. This is only happening in ie7 (not even in ie6). Help! Edit: I just found a solution which consists of giving the parent div padding-top just for ie7. So I would just like to know why does this happen, and if there is one, a cleaner solution, but I dont need more dirty hacks..

  • Conditionally embed ASP.NET MVC2 Views as resources during build in Visual Studio 2010

    - by jslatts
    I have a ASP.NET MVC2 project in VS2010 that can be deployed in two modes: standalone or plugin. In standalone mode, the views should live outside the compiled assembly as .aspx files (the default setup). In plugin mode, the views are switched (currently by hand) to embedded resources and the entire assembly is dropped into a host project folder. Currently, this requires the developer to go through each view and switch it from Build Action: "Content" to "Embedded Resource" and vice versa. I would like to create a new solution configuration to automatically grab all .aspx files and build them as resources. This SO post seems like the solution, but I would prefer not to have to edit the .csproj every single time I add a new view to the project. Is there a way to use a wild cards or some other batch/global conditionally statement to change resources from content to embedded?

  • ASP.NET MVC v1 project upgraded to VS 2010 no longer will debug. Why?

    - by Todd Brooks
    I'm getting the message "The breakpoint will not currently be hit. No symbols have been loaded for this document." I have a S#arp Architecture project (ASP.NET MVC v1) that has been opened and upgraded to be used in VS 2010. I can no longer debug the project. I'm running Windows 7 Ultimate x64 and Visual Studio 2010 Ultimate. I have IE set to be my default browser. I have the build set to debug. System.Web.Mvc is referenced in my project's lib dir. I've cleaned the solution. I've recompiled the solution. It's set to use .NET Framework 3.5. PDBs are being created and dropped into the bin directory with the DLLs. Any help will be greatly appreciated.

  • Web Service appears as website instead of developer web server

    - by stocherilac
    I recently reimaged my PC and regrabbed one of our projects from Source Safe. In our solution we have a web service that normally runs on a server, however we can build the webservice on our localhost for debugging as well. However, now whenever I grab the project from source safe it is building the webservice as a website instead of a developer web server. This is causing a variety of issue, specifically I am no longer able to specify which port I would like that webservice to use. As a result I cannot connect to our database through my local webservice. How can I change the project in my solution that controls the webservice from a website to a developer web server? MS Visual Studio 2005. MS Visual Source Safe 2005. MS SQL Server 2000. VB .NET project

  • Programatically determining maximum transfer rate

    - by dauphic
    I have a problem that requires me to calculate the maximum upload and download available, then limit my program's usage to a percentage of it. However, I can't think of a good way to find the maximums. At the moment, the only solution I can come up with is transfering a few megabytes between the client and server, then measuring how ling the transfer took. This solution is very undesirable, however, because with 100,000 clients it could potentially result in too much of an increase to our server's bandwidth usage (which is already too high). Does anyone have any solutions to this problem?

  • Direct comparator in Java out of the box

    - by KARASZI István
    I have a method which needs a Comparator for one of its parameters. I would like to pass a Comparator which does a normal comparison and a reverse comparator which does in reverse. java.util.Collections provides a reverseOrder() this is good for the reverse comparison, but I could not find any normal Comparator. The only solution what came into my mind is Collections.reverseOrder(Collections.reverseOrder()). but I don't like it because the double method calling inside. Of course I could write a NormalComparator like this: public class NormalComparator<T extends Comparable> implements Comparator<T> { public int compare(T o1, T o2) { return o1.compareTo(o2); } } But I'm really surprised that Java doesn't have a solution for this out of the box.

  • Escape doube and single backslashes in a string in Ruby

    - by Nick Gorbikoff
    Hello. I'm trying to access a network path in my ruby script on a windows platform in a format like this. \\servername\some windows share\folder 1\folder2\ Now If I try to use this as a path, it won't work. Single backslashes are not properly escaped for this script. path = "\\servername\some windows share\folder 1\folder2\" d = Dir.new(path) I tried everything I could think of to properly escape slashes in the path. However I can't escape that single backslash - because of it's special meaning. I tried single quotes, double quotes, escaping backslash itself, using alternate quotes such as %Q{} or %q{}, using ascii to char conversion. Nothing works in a sense that I'm not doing it right. :-) Right now the temp solution is to Map a network drive N:\ pointing to that path and access it that way, but that not a solution. Does anyone have any idea how to properly escape single backslashes? Thank you

  • Testing a (big) collection retrieved from a db

    - by Bas
    I'm currently doing integration testing on a live database and I have the following sql statement: var date = DateTime.Parse("01-01-2010 20:30:00"); var result = datacontext.Repository<IObject>().Where(r => r.DateTime > date).First(); Assert.IsFalse(result.Finished); I need to test if the results retrieved from the statement, where the given date is less then the date of the object, have Finished set to False. I do not know how many results I get back and currently I'm getting the first object of the list and check if that object has Finished set to false. I know testing only the first item of the list is not valid testing, as a solution for that I could iterate through the list and check all items on Finished, but putting logic in a Test is kinda going against the concept of writing 'good' tests. So my question is: Does anyone have a good solution of how to properly test the results of this list?

  • How to create an application which embeds and runs Python code without local Python installation?

    - by Robert
    Hello fellow software developers. I want to distribute a program which is scriptable by embedding the Python interpreter. What I don't want is that the user has to install Python first. So I'm looking for a solution where I distribute only the following components: my program executable and its libraries the Python library (dll/so) a ZIP-file containing all necessary Python modules and libraries. How can I accomplish this? Do you have a step-by-step recipe for me? The solution should be suitable for both Windows and Linux. Thanks in advance.

  • Extract a regular expression match in R version 2.10

    - by tovare
    Hi, I'm trying to extract a number from a string. And do something like this [0-9]+ on this string "aaaa12xxxx" and get "12". I thought it would be something like: > grep("[0-9]+","aaa12xxx", value=TRUE) [1] "aaa12xxx" And then I figured... > sub("[0-9]+", "\\1", "aaa12xxxx") [1] "aaa12xxx" But I got some form of response doing: > sub("[0-9]+", "ARGH!", "aaa12xxxx") [1] "aaaARGH!xxx" There's a small detail I'm missing Please advice :-) I'm using R version 2.10.1 (2009-12-14) Thanks ! Comments on the solution The best solution is to ignore the standard functions and install Hadley Wickham's stringr package to get something that actually makes sense. Kudos to Marek for figuring out how the standard library worked.

  • IconDownloader, problem with lazy downloading

    - by Junior B.
    My problem is simple to be described but it seems to be hard to solve. The problem is loading icons, with a custom class like IconDownloader.m provided by an official example from Apple, avoiding crashes if I release the view. I've added the IconDownloader class to my app, but it's clear that this approach is good only if the tableview is the root. The big problem is when the view is not the root one. F.e: if I start to scroll my second view (the app now load the icons) and, without leaving it the time to finish the download, I go back to root, the app crash because the view that have to be updated with new icons doesn't exist anymore. One possible solution could be implement an OperationQueue in the view, but with this approach I've to stop the queue when I change the view and restart it when I come back and the idea to have N queues don't make me enthusiastic. Anyone found a good solution for this problem?

  • Cached/offline maps for iPhone?

    - by Konstantin
    I'd like to use use maps in my application, so that there will be as less as possible traffic. Perfect solution would be caching of map slices. I know it's not possible with google maps (license). I took a look on OpenStreetMaps and it seems as good solution. The next: SDK. The only one I've found is from CloudMade. The problem is, I found no related API methods for caching/offline calls. Are there any alternative solutions?

  • Is There a Good Pattern for Creating a Unique Id based on a Type?

    - by Michael Kelley
    I have a template that creates a unique identifier for each type it is instanced. Here's a streamlined version of the template: template <typename T> class arType { static const arType Id; // this will be unique for every instantiation of arType<>. } // Address of Id is used for identification. #define PA_TYPE_TAG(T) (&arType<T >::Id) This works when you have an executable made purely of static libraries. Unfortunately we're moving to an executable made up of dlls. Each dlls could potentially have its own copy of Id for a type. One obvious solution is to explicitly instantiate all instances of arType. Unfortunately this is cumbersome, and I'd like to ask if anyone can propose a better solution?

  • Simply display RSS feed in/on aspx page

    Maybe I am being a n00b here, but for the life of me, I cant find a simple drop in type solution for displaying an rss feed inside an aspx page? I am looking for a simple solution, as when Firefox gets pointed to an rss feed, it just plainly displays it, no thrills, no fuss. I don't want to get into the xml and format it extensively. I just want a basic feed, will style it with font and a:styles. Thats it. Any ideas? EDIT: I am attempting to show a worpress "feed" inside an aspx page...
