  • jQuery won't parse my JSON from AJAX query

    - by littlecharva
    Hi, I'm having difficulty parsing some JSON data returned from my server using jQuery.ajax() To perform the AJAX I'm using: $.ajax({ url: myUrl, cache: false, dataType: "json", success: function(data){ ... }, error: function(e, xhr){ ... } }); And if I return an array of items then it works fine: [ { title: "One", key: "1" }, { title: "Two", key: "2" } ] The success function is called and receives the correct object. However, when I'm trying to return a single object: { title: "One", key: "1" } The error function is called and xhr contains 'parsererror'. I've tried wrapping the JSON in parenthesis on the server before sending it down the wire, but it makes no difference. Yet if I paste the content into a string in Javascript and then use the eval() function, it evaluates it perfectly. Any ideas what I'm doing wrong? Anthony

  • !(ReferenceEquals()) vs != in Entity Framework 4

    - by Eric J.
    Unless a class specifically overrides the behavior defined for Object, ReferenceEquals and == do the same thing... compare references. In property setters, I have commonly used the pattern private MyType myProperty; public MyType MyProperty { set { if (myProperty != value) { myProperty = value; // Do stuff like NotifyPropertyChanged } } } However, in code generated by Entity Framework, the if statement is replaced by if (!ReferenceEquals(myProperty, value)) Using ReferenceEquals is more explicit (as I guess not all C# programmers know that == does the same thing if not overridden). Is there any difference that's escaping me between the two if-variants? Are they perhaps accounting for the possibility that POCO designers may have overridden ==? In short, if I have not overridden ==, am I save using != instead of ReferencEquals()?

  • relational database: how to design this table

    - by donpal
    I'm a database newbie designing a database. I'll use SO to ask my question because it's easier to ask it on something that you can see already, but it's not the same, it will just help me understand the right approach. As you can see, there are many questions here and each can have many answers. How should I store the answers in a table? Should I store all the answers in the SAME table with a unique id (make it the key) and just a new field for the question id? What if there are 100,000 answers like there is here? Do I still store them in 1 table? What keys should I use to minimize search time when I want to search for the answers of a specific question? The database is both read and write if that makes any difference in this case.

  • displaying keyboard raises memory... but it never comes down iPhone

    - by Joshep Freeman
    Hello again. I encountered a weird behavior in memory just by displaying the default keyboard. I've just created a project with an .xib file for testing purposes. This .xib file has an UITextField element in it and it's connected in the .h via: @property(nonatomic, retain) IBOutlet UITextField *sometext; The .m has no changes but: - (void)viewDidAppear:(BOOL)animated { [someText becomeFirstResponder]; } As you see it's very very simple. The problem is that once the keyboard is shown, the memory allocated for it NEVER goes down. I've tested this scenario in another project with the only difference of having two .xib files. Standar pushViewController and popViewController calls are made. Instruments show an increase of 600kb in memory allocations [which are a lot more in the actual iPhone device]. All in all, hehehe. My question is: How do I release the memory allocated for the keyboard?.

  • GTK+ (GTKSharp) poor performance in Windows

    - by nubela
    Hi, In my Mono (C#) project that is meant to be cross-platform, I am using the GTK for the UI. However one thing I noticed is, on my netbook in Archlinux, the performance is really speedy, so events such as mouse hover, and redrawing of widgets, etc, are really fast. Compared to windows (7) on dual core CPUs, the performance is really really weak. Which perplexes me. Am I doing something wrong that is warranting this difference in performance between OSes? What are some ways I can do to optimize GTK on Windows? Its really bad to take around 0.5 secs for a hover event to kick in whereas its almost immediate on a weak(er) netbook with Linux. My code is here for the GUI layer: http://code.google.com/p/subsynct/source/browse/branches/dev/subsync#subsync/GUI Thanks!

  • Rails initializes extremely slow on ruby 1.9.1

    - by Ben Johnson
    I just got my rails 2.3.8 app running on ruby 1.9.1. To get into the console, start the webserver, anything that initializes rails, takes 3 - 4 times longer in ruby 1.9 than in ruby 1.8.7. I'm using ruby version managers so I can easily switch between ruby 1.9 and ruby 1.8.7. The speed difference happens in both production and development. I want to use 1.9 because its must faster once everything is running, but the startup time is so bad the app is timing out on Heroku on the first request. Any ideas why ruby 1.9 would be 3 - 4 times slower? I can't figure it out for the life of me.

  • Find the minimum gap between two numbers in an AVL tree

    - by user1656647
    I have a data structures homework, that in addition to the regular AVL tree functions, I have to add a function that returns the minimum gap between any two numbers in the AVL tree (the nodes in the AVL actually represent numbers.) Lets say we have the numbers (as nodes) 1 5 12 20 23 21 in the AVL tree, the function should return the minimum gap between any two numbers. In this situation it should return "1" which is |20-21| or |21-20|. It should be done in O(1). Tried to think alot about it, and I know there is a trick but just couldn't find it, I have spent hours on this. There was another task which is to find the maximum gap, which is easy, it is the difference between the minimal and maximal number.

  • Batch vs SQL statement

    - by AspOnMyNet
    a) A SQL statement is a single SQL command (for example, SELECT * FROM table1 or SET NOCOUNT ON). A batch on the other hand, is a number of SQL statements sent to the server for execution as a whole unit. The statements in the batch are compiled into a single execution plan. Batches are separated by the GO command So the only difference between SQL statement and a Batch is that each SQL statement is sent to server as a separate unit and thus is compiled separately from other SQL statements, while SQL statements in a Batch are compiled together? b) I assume one of major differences between a stored procedure and a Batch is that stored procedures are precompiled while Batches aren’t? thanx

  • Cannot combine commits using TortoiseGit

    - by JC
    I have two branches with several commits each. On one branch, I can go to the log, select two commits, and TortoiseGit shows "combine to one commit" in the context menu. On the other branch this option does not show in the context menu. Both sequence of commits is very similar; add file then modify it, so there is no difference really between the branches. What factors would cause this "combine to one commit" to not be available? I'm wondering if I should just switch to the command line.

  • How do I fix JavaHL (JNI) Not available after I have changed the logon password on my Mac?

    - by INeedHelp
    I have installed Eclipse 3.5.2 and the plugin Subversion JavaHL Native Library Adapter 1.6.9.2 and this worked without any problems. However, this morning I was forced to change the password to logon to my Mac and since then I get the message that "Subversion native library not available" when I try to save any changes. Can anyone help? I have tried to add this line (-Djava.library.path=/usr/lib/jni) to the eclipse.ini file but this didn´t seem to make any difference. Can anyone help?

  • Tomcat 5.5, Is there a max upload speed per request?

    - by maclema
    I am having an issue when uploading files to tomcat. It seems that tomcat (or something else?) will not handle the upload as fast as I can send it. When uploading multiple files concurrently I can max out my local connection upload speed (2.1MB/s). However, when uploading only one file at a time, no matter how small or large the file, the upload will max out around 400KB/s. I have tried setting the appReadBufSize higher but it makes no difference. Is there something else that would be limiting the upload speed per request? Proxy Server: CentOS 4 Apache 2 SSL Tomcat Server: CentOS 4 Tomcat 5.5.25 (Tomcat Native Library Is Installed) Java 6 Thanks! Matt

  • python: using __import__ to import a module which in turn generates an ImportError

    - by bbb
    Hi there, I have a funny problem I'd like to ask you guys ('n gals) about. I'm importing some module A that is importing some non-existent module B. Of course this will result in an ImportError. This is what A.py looks like import B Now let's import A >>> import A Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/tmp/importtest/A.py", line 1, in <module> import B ImportError: No module named B Alright, on to the problem. How can I know if this ImportError results from importing A or from some corrupt import inside A without looking at the error's string representation. The difference is that either A is not there or does have incorrect import statements. Hope you can help me out... Cheers bb

  • Enumerator Implementation: Use struct or class?

    - by Hosam Aly
    I noticed that List<T> defines its enumerator as a struct, while ArrayList defines its enumerator as a class. What's the difference? If I am to write an enumerator for my class, which one would be preferable? EDIT: My requirements cannot be fulfilled using yield, so I'm implementing an enumerator of my own. That said, I wonder whether it would be better to follow the lines of List<T> and implement it as a struct.

  • Asp.Net application/web service not working on Vista/IIS7: access right problem?

    - by Achim
    I have an .Net 3.5 based web service running at http://localhost/serivce.svc/. Then I have a Asp.Net application running at http://localhost/myApp. In Application_Load my App reads some XML configuration from the web service. That works fine on my machine, but: On Vista with IIS7 the request to the web services fails. The web service can be accessed via the browser without any problem. I configured the app pool of my App to run as admin. I added the admin to the IIS_USRS group, but it still cannot access the web service. impersonate=true/false seems not to make a difference.

  • Weird in my UIImagePickerController with camera

    - by Chun
    Hi everyone: I met a problem on using camera by scratch on iphone. Other people's code just run fine on my 3GS. But my code doesn't. When I implemented a UIViewController controller, and I add the following code in viewdidload: UIImagePickerController *picker = [UIImagePickerController alloc] init]; picker.source = UIImagePickerControllerSourceTypeCamera; picker.delegate = self; //Previously added all the delegate properly [self presentModalViewController:picker animated:YES]; Nothing comes out. I checked in the debugger, it shows that the picker is allocated, but here is the major difference between my and success one. picker._imagepickerflag.visible = 0; //others show 1; picker.UINavigationController._containerView: 0x0 ; // others have value. Can anyone help me on this, is there something wrong? Thank you.

  • emacs: force ido-mode to forget history...

    - by Stephen
    Hi, I wonder if I can keep ido from not remembering my history and only show completions for files that are in the current directory when I am searching for a file. I understand that this history feature is useful at times, but I often end up editing the incorrect file because I think I am editing file called 'abc.txt' in the current directory but in fact I am editing the file by the same name in another one that I previously visited (often happens when there is not an 'abc.txt' in the current directory, as I mistakenly assume). From reading the ido.el file I thought to set in my .emacs file (also evaluated these expressions in running emacs instance): (custom-set-variables '(ido-enable-last-directory-history nil) '(ido-record-commands nil) ) and deleted a file called .ido.last in ~/, but still it remembers some previous files I've visited before making these changes. How can I purge my previous history, and I am not entirely sure what the difference between the two variables above are but seems to have done the trick to keep ido from remembering files I visit in the future? Thanks for your help!

  • How can I provide a different rendering target to Direct2D?

    - by fingerprint211b
    I'm using Direct2D in C# to render a small gui framework for my research project. I'm not very used to working on Windows or with DirectX. I'm using a Windows Forms control to create a render target, and msdn warns that since it uses BindDC, a the larger the rendering target, the worse the performance will be (which turned out to be a dramatic difference, when I maximize the window, I get around 15 fps). What would be a better way to create a render target for Direct2D? Is there a way to create a window and render directly to it, instead of rendering to a control's buffer first, and then rendering that? If so, how? Sorry if my English sucks, not my native language.

  • How to detect if a page is an RSS or ATOM feed

    - by Pepper
    Hello, I'm currently building a new online Feed Reader in PHP. One of the features i'm working on is feed auto-discovery. If a user enters a website URL, the script will detect that its not a feed and look for the real feed URL by parsing the HTML for the proper tag. The problem is, the way im currently detecting if the URL is a feed or a website only works part of the time, and I know it can't be the best solution. Right now im taking the CURL response and running it through simplexml_load_string, if it can't parse it I treat it as a website. Here is the code. $xml = @simplexml_load_string( $site_found['content'] ); if( !$xml ) // this is a website, not a feed { // handle website } else { // parse feed } Obviously, this isn't ideal. Also, when it runs into an HTML website that it can parse, it thinks its a feed. Any suggestions on a good way of detecting the difference between a feed or non-feed in PHP? Thanks, Pepper http://feedingo.com

  • How powerful is the <script> tag in ASP.NET ?

    - by MarceloRamires
    I'm new at web development with .NET, and I'm currently studying a page where I have both separated codebehinds (in my case, a .CS file associated to the ASPX file), and codebehind that is inside the ASPX file inside tags like this: <script runat="server"> //code </script> Q1:What is the main difference (besides logical matters like organization, readability and ETC), what could be done in one way that could not be done in another? What is each mode best suited for ? Q2:If I'm going to develop a simple page with database connection, library imports, access to controls (ascx) and image access in other folders.. which method should I choose ?

  • Dealing with HTTP Status Codes in PHPUnit_Extensions_Selenium2TestCase

    - by frosty
    I have a series of tests that I'm running for an Open Source Project, I'd like to get the status code of the curl request that is made to determine the difference of a code change breaking functionality vs a code change breaking the site completely. class ExampleTest extends PHPUnit_Extensions_Selenium2TestCase { public function setUp() { $this->setBrowser('firefox'); $this->setBrowserUrl('http://localhost'); } public function testForError() { $this->url('/'); $this->assertNotEmpty($this->title()); } } That's an example of how I'm going about it now, but I'd like to have some concrete information. Short of getting the information from the CURL request, I'm not really sure how to go about this...

  • How to automatically include generated source files into a C# project in Visual Studio?

    - by Charles Prakash Dasari
    I have a situation where I need to generate a bunch of C# code files in a prebuild step of a project and include the generated files into the current project for compilation. Is there a way to do this cleanly without having to muck with the project file every time the prebuild step is run? My solution should work for both IDE based build and a Team Build based on MSBuild. Since both are MSBuild based, I suspect there won't be much difference; but wanted to call it out. Any help is greatly appreciated, thanks!

  • authlogic auto_register feature using my options

    - by holden
    I have auto registration working with authlogic using gaizka's version of authlogic_openid which I found on Github since pelle's original addition of the feature seemed to cause issues. http://github.com/gaizka/authlogic%5Fopenid http://stackoverflow.com/questions/1476953/using-authlogic-to-auto-create-users-bypassing-explicit-user-registeration This one works fine however when using the auto_register feature it ignores my options for authlogic such as retrieving the email from the openid provider... any ideas what I'm doing wrong? Hhere's the example: http://big-glow-mama.heroku.com/ http://github.com/holden/authlogic_openid_selector_example/tree/with-facebook/ You can see the difference if you register vs. login... #user.rb class User < ActiveRecord::Base acts_as_authentic do |c| c.validate_login_field = false # optional, but if a user registers by openid, he should at least share his email-address with the app c.validate_email_field = false # fetch email by ax c.openid_required_fields = [:email,"http://axschema.org/contact/email"] #c.required_fields = ["http://axschema.org/contact/email"] # fetch email by sreg #c.optional_fields = ["email"] end #private method to deal with emails goes here end #UserSession.rb class UserSession < Authlogic::Session::Base auto_register logout_on_timeout true end
