  • javascript "this" points to Window object again

    - by terrani
    Hello, I asked a question on http://stackoverflow.com/questions/2719643/javascript-this-points-to-window-object regarding "this" points to Window object. here is source code var archive = function(){} archive.prototype.action = { test: function(callback){ callback(); }, test2: function(){ console.log(this); } } var oArchive = new archive(); oArchive.action.test(oArchive.action.test2); Tim Down wrote "but that function is then called using callback(), which means it is not called as a method and hence this is the global object". What are differences between calling a function by its actual name and callback() as shown on the source code? How does console.log(this) in test2 points to Window when it is inside archive.action???

  • What's missing in ASP.NET MVC?

    - by LukaszW.pl
    Hello stackoverflow, I think there are not many people who don't think that ASP.NET MVC is one of the greatest technologies Microsoft gave us. It gives full control over the rendered HTML, provides separation of concerns and suits to stateless nature of web. Next versions of framework gaves us new features and tools and it's great, but... what solutions should Microsoft include in new versions of framework? What are biggest gaps in comparison with another web frameworks like PHP or Ruby? What could improve developers productivity? What's missing in ASP.NET MVC?

  • As a consultant should I charge my clients for developing specs?

    - by Chris
    I'm trying to transition into some programming consulting work. A friend of my former employer is interested in having me "develop a spec," which I take to mean come up with some technology requirements and time estimates (e.g. milestones). Do developers normally charge for this? I'm imagining it's basically the same kind of workload that creating a bid for a project would take. On one hand, consultants don't get paid for the time they put into the legwork of a bid. On the other hand, this is probably go to be more than a couple hours of work, and my time is valuable. Any advice? Any sites besides SO I could go to get advice with this kind of stuff? (Sorry if this isn't programming-related enough for StackOverflow! I don't know where else to get advice!)

  • The Definitive Guide To Website Authentication (beta)

    - by Michiel de Mare
    Form Based Authentication For Websites Please help us create the definitive resource for this topic. We believe that stackoverflow should not just be a resource for very specific technical questions, but also for general guidelines on how to solve variations on common problems. "Form Based Authentication For Websites" should be a fine topic for such an experiment. It should include topics such as: how to log in how to remain logged in how to store passwords using secret questions forgotten password functionality OpenID "Remember me" checkbox Browser autocompletion of usernames and passwords secret urls (public urls protected by digest) checking password strength email validation and much more It should not include things like: roles and authorization http basic authentication Please help us by Suggesting subtopics Submitting good articles about this subject Editing the official answer (as soon as you have enough karma) UPDATE: See the terrific 7-part series by Jens Roland below.

  • Free (as in beer) Reverse Image Search API/Library/Service

    - by Bauer
    TinEye provides a great way to "reverse" search by image (i.e. upload/transload an image and have multiple possible sources of that image returned as results.) Since screen-scraping is messy and unreliable, I'm looking for a free API/library/web-service that could offer the same (or similar) reverse-image search function. At present, TinEye offers a commercial API, but since I'll only be using the service for small personal projects, it's hard to justify the cost of the service (the lowest being 1,000 searches for $70 USD). Is anyone aware of such a free service? Or is there a simpler way to approach this (programmatic solution; any language)? I understand that this is a tall order, and submitting the question is really only a last resort in the hope that there is some solution. Example image search is 99designs' StackOverflow logo competition entry by wolv

  • How do I get Git's latest stable release version number?

    - by MattDiPasquale
    I'm writing a git-install.sh script: http://gist.github.com/419201 To get Git's latest stable release version number, I do: LSR_NUM=$(curl -silent http://git-scm.com/ | sed -n '/id="ver"/ s/.*v\([0-9].*\)<.*/\1/p') 2 Questions: Refactor my code: Is there a better way programmatically to do this? This works now, but it's brittle: if the web page at http://git-scm.com/ changes, the line above may stop working. PHP has a reliable URL for getting the latest release version: http://stackoverflow.com/questions/288206/is-there-a-site-which-simply-outputs-the-latest-stable-version-numbers-of-php-and Is there something like this for Git? This comes close: http://www.kernel.org/pub/software/scm/git/

  • How to store account-specific information in ASP.NET MVC 2

    - by PR_
    I have an ASP.NET MVC 2 web application. There are two tables like "FIRST_KIND_OF_USERS" and "SECOND_KIND_OF_USERS". Both are mapped to the default aspnet_users table via UserId column. Each of them has it's own integer primary key column like "FirstKindOfUsersId". When a user is trying to add some data to the database, for instance, "Create a new Task" I would like to add a new row in Tasks table with "FirstKindOfUsersId" value. Where should I store or get this value? At the moment I have these possible solutions: Get "FirstKindOfUsersId" value by User.Identity.Name each time; Use SESSION[] for storing these values (Where and when should I save these ones?) Use FormsAuthenticationTicket and create own custom IIdentity class. (http://stackoverflow.com/questions/1064271/asp-net-mvc-set-custom-iidentity-or-iprincipal) Which approach is better? And if I pick the 3rd one, how to save the necessary data property and at which stage?

  • Is Alpha Five Version 10 really all that its reported to be?

    - by Gary B2312321321
    I came across this RDMS via the advert on stackoverflow. Seems to be in the vein of MS Access / Filemaker / Apex database devlopment tools but focused on web based applications. It quotes rave reviews from EWeek and a favourable mention from Dr Dobbs regarding its ability to create AJAX web applications without coding. The Eweek review, apparently written by an ASP.NET programmer, goes on to proclaim the ease at which apps can be extended using the inbuilt XBasic language and how custom javascript can easily be added without wading through code. Has anyone here built a web app with Alpha 5? Does anyone have comments on the development process, the speed of it or limitations they encountered along the way? To me it seems Oracle APEX comes closest to the feature set, has anyone programmed in both and have any comments?

  • GWT on Python App Engine

    - by Koran
    Hi, I have a python app engine code (matured backend) - and we are now planning to have a front end for that code. I was wondering whether it is possible to implement GWT as the front end. Even though Alex Martelli in this post [1] mentions it is not possible, a comment to that post suggests that it is indeed possible using rpc over json for GWT. I was unable to understand how this is possible. In app.yaml file, we have to specify the language to be python, right? In that case, how can it compile GWT based on JAVA? Are there any examples on anyone doing that? Can someone help me out? It would be extremely helpful.

  • Immutability of big objects

    - by Malax
    Hi StackOverflow! I have some big (more than 3 fields) Objects which can and should be immutable. Every time I run into that case i tend to create constructor abominations with long parameter lists. It doesn't feel right, is hard to use and readability suffers. It is even worse if the fields are some sort of collection type like lists. A simple addSibling(S s) would ease the object creation so much but renders the object mutable. What do you guys use in such cases? I'm on Scala and Java, but i think the problem is language agnostic as long as the language is object oriented. Solutions I can think of: "Constructor abominations with long parameter lists" The Builder Pattern Thanks for your input!

  • IE Cannot open the internet site (no JS on the page)

    - by Nic Hubbard
    I know that there are many posts about this on Stackoverflow, but this one is different. All of the other fixes to this have to do with javascript, but I don't even have javascript on my page. None. And I am still getting this error. Was there any other reasons why this error was being caused? Also, it only happens when I visit my top navigation links, rather than the page directly from the url. Take a look at: http://www.mayandivers.com/see EDIT: This is happening in IE6/7.

  • Java threadpool functionality

    - by cpf
    Hi stackoverflow, I need to make a program with a limited amount of threads (currently using newFixedThreadPool) but I have the problem that all threads get created from start, filling up memory at alarming rate. I wish to prevent this. Threads should only be created shortly before they are executed. e.g.: I call the program and instruct it to use 2 threads in the pool. The program should create & launch the first 2 Threads immediately (obviously), create the next 2 to wait for the previous 2, and at that point wait until one or both of the first 2 ended executing. I thought about extending executor or FixedThreadPool or such. However I have no clue on how to start there and doubt it is the best solution. Easiest would have my main Thread sleeping on intervals, which is not really good either... Thanks in advance!

  • Find folder name based on string value with batch

    - by MaQleod
    I need to return a full directory name from inside a specified directory that contains .default in the folder name. Basically I'm adding a line in a backup script to backup firefox bookmarks, but the profile name is going to be different on every machine and I need a way to find the folder the bookmarks.html file resides without knowing the firefox profile name I've looked at FIND and FINDSTR but neither seem to be what I need. I also looked at this post: http://stackoverflow.com/questions/2252785/windows-batch-file-get-folders-path-and-store-them-in-variable It was closer to what I'm looking for, but I just need a folder name, and to use something like regexp to find it Any suggestions on commands to look at or strategies to use?

  • Zend Framework command line see errors

    - by sims
    I'm using a method outline by gregor (http://stackoverflow.com/questions/143320/create-cronjob-with-zend-framework) to create command line execution for parts of my application such as cron jobs, admin tasks, and the like. It works, however, no errors get reported when I create a new object that has not been defined (misspelling) and other such mistakes. I would have thought that php would report an error, but it fails silently. What is the reason for this? Is there a better way to achieve my goal? Or how can I implement this so that I can see errors? Many thanks! Here is the code: in public/index.php if(!defined('RUN_APP') || RUN_APP == true) { $application->bootstrap()->run(); } application/cron.php define("RUN_APP",false); require(realpath('/var/www/domain/public/index.php')); $application->bootstrap(); //the rest

  • Network Load Balancing (NLB): is it suitable for "stateful" ASP.NET applications?

    - by micha12
    Hi everybody, I have posted the following question concerning ASP.NET web farms. http://stackoverflow.com/questions/1816756/how-to-create-an-asp-net-web-farm/ Guys recommended using Network Load Balancing (NLB) as a primary way of creating a web farm. However, Wikipedia says that "NLBS is intended for ... stateless applications". Our web application, however, is absolutely "stateful": it is a closed site to which users will have access by login and password, and information for every user will be different: people will see their own trades and operations. Should we still use NLB in this scenario? Thank you.

  • Can't get up with RIA demo: part 2

    - by Budda
    Here is a topic: http://stackoverflow.com/questions/2507734/cant-get-up-with-ria-demo where I've described problem with getting access to DomainContext object on the client. That time problem was resolved himself (without any actions from my side, with Visual Studio restart). At the moment, I had the same problem on another PC (Vista x64, VS2008, Silverlight 3.0, RIA Services Toolkit): ThomasDomainContext class that inherits DomainContext was not visible from the page's codebehind file. Again, it was resolved after VS restart and after that I got another problem: Error 1 'VfmElita.Web.ClientBin.ThomasDomainContext' does not contain a definition for 'employee' and no extension method 'employee' accepting a first argument of type 'VfmElita.Web.ClientBin.ThomasDomainContext' could be found (are you missing a using directive or an assembly reference?) D:\Project\Budda\VFMElita\VfmElitaSilverlightClient\MainPage.xaml.cs for the following lines of code (error is noticed for the 31st line): 30: var context = new ThomasDomainContext(); 31: grid1.ItemsSource = context.employee; 32: context.Load(context.GetEmployeeQuery()); Any help is welcome. P.S. Please note, that source code create on the 1st machine is successfully compilable and launchable

  • How to effectively draw on desktop in C#?

    - by Lazlo
    I want to draw directly on the desktop in C#. From searching a bit, I ended up using a Graphics object from the Desktop HDC (null). Then, I painted normally using this Graphics object. The problem is that my shapes get lost when any part of the screen is redrawn. I tried a While loop, but it actually ends up drawing as fast as the application can, which is not the update rate of the desktop. Normally, I would need to put my drawing code in a "OnPaint" event, but such thing does not exist for the desktop. How would I do it? Example code: http://stackoverflow.com/questions/1536141/how-to-draw-directly-on-the-windows-desktop-c

  • Separating null byte separated UNICODE C string.

    - by Ramblingwood
    First off, this is NOT a duplicate of: http://stackoverflow.com/questions/1911053/turn-a-c-string-with-null-bytes-into-a-char-array , because the given answer doesn't work when the char *'s are Unicode. I think the problem is that because I am trying to use Unicode and thus wchar_t instead of char, the length of each character is different and thus, this doesn't work (it does in non-unicode): char *Buffer; // your null-separated strings char *Current; // Pointer to the current string // [...] for (Current = Buffer; *Current; Current += strlen(Current) + 1) printf("GetOpenFileName returned: %s\n", Current); Does anyone have a similar solution that works on Unicode strings? I have been banging my head on the this for over 4 hours now. C doesn't agree with me.

  • Why does A* path finding sometimes go in straight lines and sometimes diagonals? (Java)

    - by Relequestual
    I'm in the process of developing a simple 2d grid based sim game, and have fully functional path finding. I used the answer found in my previous question as my basis for implementing A* path finding. (http://stackoverflow.com/questions/735523/pathfinding-2d-java-game). To show you really what I'm asking, I need to show you this video screen capture that I made. I was just testing to see how the person would move to a location and back again, and this was the result... http://www.screenjelly.com/watch/Bd7d7pObyFo Different choice of path depending on the direction, an unexpected result. Any ideas?

  • Anyone realize success using Apple Mac OS 10.6 and Parallels 5 for a Visual Studio Dev machine?

    - by Buffalo
    Greetings my wonderful StackOverflow family :) I grew up using Windows and switched to OSX as a Computer Science major in College. I've recently started my first real software developer job, and have a ThinkPad and Windows XP for developing ASP.NET / MS SQL applications (Visual Studio 2008). Question: Basically, I am wondering if any developers out there have had real success creating ASP.NET applications on a Mac using a VM? I've been fighting with Parallels 5 all week and finally have Windows 7 and VS 2008 running but my hot-keys are all screwed up. Is it worth the work to keep beating this thing into submission? Should I give up? Should I give Mono a try instead? Thanks Folks, I can't wait to see what you all think!

  • Why is floating point byte swapping different from integer byte swapping?

    - by CJ
    I have a binary file of doubles that I need to load using C++. However, my problem is that it was written in big-endian format but the fstream operator will then read the number wrong because my machine is little-endian. It seems like a simple problem to resolve for integers, but for doubles and floats the solutions I have found won't work. How can I (or should I) fix this? I read this as a reference for integer byte swapping: http://stackoverflow.com/questions/105252/how-do-i-convert-between-big-endian-and-little-endian-values-in-c

  • Python - which multi platform GUI framework to use?

    - by Iacopo
    Hi, I've written a Python GUI application and made it run on Linux, Windows and Mac. The framework I'm using is PyGtk. The final result is not really good: the application looks horrible on Mac, and it is not really 'native' neither on Windows. Furthermore on Mac the windows' behavior is sometimes wrong, with modal dialogs appearing below the main windows. I've explored other frameworks and I've found that a porting may be really hard: PyQt it is huge, difficult to install and to distribute under Mac; PyGui is poor: I need tables and tree views at least; wxPython state explicitly that you have to use a custom python build for Mac Tkinter: didn't check it, only have the impression that it is obsolete I know this question may appear similar to http://stackoverflow.com/questions/394039/which-python-gui-framework but in that thread the portability issue is not really taken in account. Windows and Mac are a must, since most of my user have that systems. Can you also suggest some books?

  • Caching issues with TDBadgedCell

    - by Wolfgang Schreurs
    This post is closely related to my previous post: http://stackoverflow.com/questions/2201256/tdbadgedcell-keeps-caching-the-badgenumber The "badge" from TDBadgedCell keeps caching the numbers. A very simple example is shown here: - (UITableViewCell *)tableView:(UITableView *)_tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; TDBadgedCell *cell = (TDBadgedCell *)[_tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[TDBadgedCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; } [cell setBadgeColor:[UIColor blackColor]]; [cell setBadgeNumber:[indexPath row]]; [[cell textLabel] setText:[NSString stringWithFormat:%@"%d", [indexPath row]]]; return cell; } Anyone has any clue why this happens? The textLabel and detailTextLabel don't cache the data. Any additonal info would be welcome as well, as I seem to have a lot of issues with the caching of graphics in UITableViewCells. Any best practices or other useful information would be most welcome.

  • F# Extention Methods on Lists, IEnumberable, etc

    - by flevine100
    I have searched StackOverflow (and other sources) for this answer, but can't seem to find anything. In C#, if I had a widget definition, say: class widget { public string PrettyName() { ... do stuff here } } and I wanted to allow for easy printing of a list of Widgets, I might do this: namespace ExtensionMethods { public static PrintAll( this IEnumerable<Widget> widgets, TextWriter writer ) { foreach(var w in widgets) { writer.WriteLine( w.PrettyName() ) } } } How would I accomplish something similar with a record type and a collection (List or Seq preferrably in F#). I'd love to have a list of Widgest and be able to call a function right on the collection that did something like this. Assume (since it's F#) that the function would not be changing the state of the collection that it's attached to, but returning some new value.

  • Why this doesn't work: [MySQL][ODBC 5.1 Driver]Access denied for user

    - by bvandrunen
    So I know that there is a very similar question to this all over the web as well as stack overflow: http://stackoverflow.com/questions/2539961/error-access-denied-for-user-mysql-server but my question I think is different. So I have set up a linked server and it works...I have the correct permissions set up for my IP's that I am using. However the problem arises when our user "webuser@correctIP" tries to access it. Therefore, any user using window authentication is allowed to access it and works great...but any that are not using windows authentication are blocked. However, I have tried all the common solutions such as setting up a strict password, changing security settings in Microsoft SQL Server etc. Nothing is working. Any help is appreciated. Thanks. FYI: I am using this from Microsoft SQL Server 2008 - mysql (through myphpadmin)
