  • Facebook Developer Toolkit doesn't redirect after authorization

    - by Mika Kolari
    I have a small facebook test app (iframe) based on sample http://blogs.claritycon.com/blogs/kevin_marshall/archive/2009/10/06/facebook-developer-toolkit-3-0-asp-net-mvc-sample.aspx public class HomeController : Controller { public ActionResult Index() { var api = this.GetApi(); var userId = api.Session.UserId; return View(); } // redirects to Index // which doesn't redirect back here [FacebookAuthorization(IsFbml = false)] public ActionResult About() { var api = this.GetApi(); // goes here without FacebookAuthorization // but userId = 0 var userId = api.Session.UserId; return View(); } } When I try to go to 'About' page, FacebookAuthorizationAttribute redirects to 'Index' for authentication. The problem is, it never redirects back to 'About'. What am I doing wrong here?

  • [jQuery] JSON response is null, but the URL is echoing correctly.

    - by b. e. hollenbeck
    I have a form being AJAX'd in by jQuery on a page with multiple forms. I'm performing the following function, which is a wrapper for the $.ajax function: function do_json_get(uri){ var ret = ''; var url = AJAX_URL + uri; $.ajax({ type: 'GET', url: url, async: false, success: function(data) { ret = data.html; }, dataType: 'json' }); return ret; } When I go to the AJAX server directly (which is rendering the form in PHP), I get the raw JSON response - so I know the server is outputting to the browser, and the AJAX server is doing other things like setting the proper cookies, so I know that the connection is good (I get a 200 response code). Yet the data object is coming back null. What else could I be missing?

  • Can squid forward DNS queries to a DNS server?

    - by pravin
    This might something be completely impossible to achieve, but before I give it a shot thought I might get some advice from a fellow geek. Would squid proxy DNS queries as well? I would like to forward DNS queries to go through squid and use squid's DNS error page, of course by customizing it. I see the DNS queries are hitting my squid box on UDP port 53. I can setup a port forwarding so that all these queries get sent to squid's port 3128. But would squid understand its a DNS query and forward those queries to the dns server set in squid.conf? I hope my question is clear but please shout up and I would be glad to give you some more info if needed. Thanks guys!

  • Using listpreference and getting the key works but no ok button...

    - by Allan
    I'm using listpreference in my android app and getting my key values and all is well and works good (now that you guys have helped me) BUT - when my listpreference menus popup, they only contain a cancel button. Let's say the user is choosing between red, blue, and green. When the listpreference dialog first pops-up, the dialog only shows a cancel button. Because of that, the dialog disappears as soon as the user selects their choice. I would like it so that when the user chooses their setting, they see the radio button get highlighted and then they go ahead and click the ok button...but I don't have an ok button and can't figure out why. Any help would be awesome...al

  • Calculating string sizes on iPhone on a background thread

    - by jbrennan
    I've got some somewhat hefty string size calculations happening in my app (each one takes close to 500ms, and happens when the user scrolls to a new "page" in my app (like the Weather app). The delay only happens once per page, as the calculation only needs to be run once (and can even be cached for subsequent launches with the same data). Anyway, I still like to not block the UI for this type of work, as to me it screams using threads, but I know UIKit is not meant to be used from other threads. (I know NSString is not part of UIKit, but the string sizing methods are part of the UIKitAdditions...) So how should I go about doing this? What's the best way to not block the UI and do so safely?

  • Floating point arithmetic is too reliable.

    - by mcoolbeth
    I understand that floating point arithmetic as performed in modern computer systems is not always consistent with real arithmetic. I am trying to contrive a small C# program to demonstrate this. eg: static void Main(string[] args) { double x = 0, y = 0; x += 20013.8; x += 20012.7; y += 10016.4; y += 30010.1; Console.WriteLine("Result: "+ x + " " + y + " " + (x==y)); Console.Write("Press any key to continue . . . "); Console.ReadKey(true); } However, in this case, x and y are equal in the end. Is it possible for me to demonstrate the inconsistency of floating point arithmetic using a program of similar complexity, and without using any really crazy numbers? I would like, if possible, to avoid mathematically correct values that go more than a few places beyond the decimal point.

  • Ruby on Rails: strange voting increment behavior

    - by Justin Meltzer
    So I have an up and a downvote button that inserts a vote with a value of 1 or -1 into the database. This works correctly. Then, I display the total vote count for that element by summing up its votes' values. However, this isn't working correctly, because the vote sum display is acting really strange: The first vote on a video doesn't seem to increment it at all. Then the second vote does. If I go from an upvote to a downvote, it increments up once, and then the next downvote is down. This is difficult to explain, but maybe you can figure out what is wrong with my code. I have this function in my Video model (the element that is voted on, it has_many video_votes): def vote_sum read_attribute(:vote_sum) || video_votes.sum(:value) end I also have this in my VideoVote model: after_create :update_vote_sum private def update_vote_sum video.update_attributes(:vote_sum => video.vote_sum + value) end What am I doing wrong?

  • Integrate Zend translator into my app

    - by clinisbut
    Hello. I wish to use the Translator classes of Zend framework in my app, but I don't want to include the whole framework. I grabbed the: Locale folder Translate folder Exception.php Loader.php Locale.php Registry.php Translate.php and copied into a custom folder named zend.translator. Obviously I had to edit all them to adjust the includes to the new path... Is this the way to go? I'm worried to have to edit all those files every time a new version is released.

  • Silverlight isolated storage: what identifies an "application"?

    - by Joe White
    The docs for Silverlight's IsolatedStorageFile.GetUserStoreForApplication just say that the isolated storage is specific to the "application", and that each different application will have its own storage independent of all other "applications" (but with one quota for the entire domain). That's great, but I haven't found anything yet that explains just what "application" is supposed to mean (either in the Silverlight docs or the regular .NET Framework docs). What information does Silverlight, in particular, use to decide that "this is application A" and "this is application B"? Does it just go off the URI to the .xap file, or what?

  • Simple example of popup authentication with Facebook Graph API

    - by ensnare
    Trying to get Facebook to authenticate my users via a javascript popup. Right now, I have: <input type="button" value="Connect with Facebook" onclick="window.open('https://graph.facebook.com/oauth/authorize?client_id=XXXXXXXXXXX&redirect_uri=http://example.com/step2&display=popup')" /> But when the user logs in via Facebook, the popup just displays the Facebook.com homepage. I'd like for the popup to authenticate the user and go away so that I can start retrieving user data from the graph api. Is there a better / easier way to do this? Simple examples are appreciated. Thank you.

  • Mobile development decision - Future wise (Iphone,android,symbian)

    - by Idan
    Hi, I would like to learn mobile development, but I'm not sure which category would be the most cost effective one. I know it's kind of a prophecy question, but anyhow, suggestions would be welcomed. So, as i'm pretty familiar with C++ development , I though about learning QT. I understand that using QT, I can develop once and then deploy to symbian,Mee-go, and of course to windows, linux and more. (does that mean I won't have to lean each OS internal calls, and just learn the QT library ? ) Learning development for android , mean I will have to learn Java, which is not my preferred way of action right now. Another option is to learn Objective-C, but as it only apply to Iphone development, I think it's a pretty narrow zone for me. I want to learn a library, which would be a wise decision career wise. Any recommendations ?

  • Graph databases and Php

    - by stagas
    I want to use a graph database using php. Can you point out some resources on where to get started? Is there any example code / tutorial out there? Or are there any other methods of storing data that relate to each other in totally random/abstract situations? Very abstract example of the relations needed: John relates to Mary, both relate to School, John is Tall, Mary is Short, John has Blue Eyes, Mary has Green Eyes, query I want is which people are related to 'Short people that have Green Eyes and go to School' - answer John It is possible in MySQL but it would require a fixed set of attributes/columns for each item and a complex non-flexible query, instead I need every attribute to be an item by itself and instead of 'belonging' to something, to be 'related' to something.

  • Small web-framework like Sinatra, Ramaze etc in .NET

    - by Christian W
    Are there any similar frameworks like Sinatra, Ramaze etc in .NET? I'm in theory after a framework that let's me create an entire webapp with just one classfile (conceptually) like Sinatra. I'm going to use it for something work-internal, where ASP.NET MVC is too "big" (and I get confused by it's usage) and I have WebForms up to my ears right now (doing a big webforms based project, currently hating it ;) ) Any suggestions? Oh, and I need to be able to host it in IIS. I would go for IronRuby with Sinatra, but I can't find a step-by-step tut for setting it up in IIS ;)

  • postgres - ERROR: syntax error at or near "COST"

    - by cino21122
    EDIT Taking COST 100 out made the command go through, however, I'm still unable to run my query because it yields this error: ERROR: function group_concat(character) does not exist HINT: No function matches the given name and argument types. You may need to add explicit type casts. The query I'm running is this: select tpid, group_concat(z) as z, group_concat(cast(r as char(2))) as r, group_concat(to_char(datecreated,'DD-Mon-YYYY HH12:MI am')) as datecreated, group_concat(to_char(datemodified,'DD-Mon-YYYY HH12:MI am')) as datemodified from tpids group by tpid order by tpid, zip This function seems to work fine locally, but moving it online yields this error... Is there something I'm missing?

  • Which Dependency Injection Tool Should I Use? (2)

    - by Mendy
    The original post is: Which Dependency Injection Tool Should I Use? While the original post is good, in this days I see a lot of people using StructureMap as their Dependency Injection tool, and in the original post no one even took it seriously. In addition, this quote: If I had to choose today: I would probably go with StructureMap. It has the best support for C# 3.0 language features, and the most flexibility in initialization. Which Dependency Injection Tool Should I Use? Out of this ones: Unity Framework - Microsoft StructureMap - Jeremy Miller Castle Windsor NInject Spring Framework Autofac Managed Extensibility Framework

  • System.Net.WebProxy in .NET Client

    - by NealWalters
    I don't yet have a good understanding of how the network is set up at my current client, but here is my issue. The vendor has a normal URL, but it might be a leased line. I have a .NET program that calls an external .asmx service. If I go to IE, Connections, LAN Settings, and uncheck "Automatic detect settings" and uncheck "Use Automatic Configuration Sript", then the .NET program runs and access the web service fine. But then, to access internet again from the browser, I have to re-check the two boxes, and so on throughout the day while we are testing and browsing. I'm hoping to put some code like this in the .NET program to avoid us having to constantly change: if (chkUseProxy.Checked) { myclient.Proxy = new System.Net.WebProxy(""); } I tried null and empty string and so far not able to connect without errors. Is this possible, and if so, what might be the correct parms for the constructor? Or are there other objects or properties that would need to be set? Thanks, Neal Walters

  • getting rid of ruby gems that won't die

    - by holden
    I've got a few ruby gems that won't go away. I think it has to do with when I installed them. Occasionally I have forgotten to use "sudo" before doing a gem install, which results in a write error and from what I can gather puts a copy of the gem in my user directory instead of somewhere it can run. But gem uninstall doesn't work. It continually shows up in 'gem list' but can't uninstall it from either gem uninstall, or sudo gem uninstall. I tried directly deleting one gem after finding the path in my 'gem environment', but that still left the gem on the list. Also is it possible just to remove all gems and start from scratch? These are driving me nuts. I'm running OS X. Thanks,

  • How to use Page Object pattern with Cucumber and Webrat / Selenium?

    - by Will Sargent
    I'm looking at a cucumber test suite that is somewhat brittle right now; many small steps, and no knowledge of the page itself. I'd like to factor out the logic involved in the step definitions inside a series of Selenium PageObjects. As seen here. However, because I'm using Webrat and not Selenium, everything has to go through the Webrat model. So I cannot do class MyPage < Selenium::WebPage end because that adds a direct dependency. So I have to route everything through Webrat while still maintaining the Selenium Page object goodness. No documentation on this that I can see: if someone has anything on Webrat + PageModel I'd love to see it.

  • Winforms web browser control not firing document complete with AJAX web site.

    - by ajl
    The VB.Net desktop app uses the IE browser control to navigate the web. When a normal page loads the document_complete event fires and I can read the resulting page and go from there. The issue I am having is that the page I am driving is written with AJAX, so the document complete event never fires. Furthermore, when you view the source of the page after it loaded a new portion via AJAX, it hasn't change. How are people handling this? What are my options?

  • UITableView, force to snap to whole UITableViewCell at top of table

    - by Adam Eberbach
    I have a need to make a UITableView only display whole cells at the top of the cell, so when the table is moved or scrolled it should animate to make a whole cell visible at the top of the table if it has happened to stop with a cell partially off the top. This can be easily done using visibleCells and scrollToRowAtIndexPath methods of UITableView, BUT the cell should not always scroll down to move the partial cell into view - if the cell at top is more than 50% gone it should go completely with the next cell (i.e. index 1 in the array returned by visibleCells) moving to the top of the table. I've tried a few things to make this happen but I don't think I am understanding the way frame and bounds work between a UITableView and its UITableViewCells. Any help?

  • Flex/Actionscript: Unable to add archive file

    - by biggusjimmus
    I have an Flex 4 application that I am developing in Flash Builder 4. I'm trying to use a library developed by a coworker, which was delivered as an SWC. I added the library to the Library Path in the project properties. Component set: MX + Spark, Framework linkage: Merged into code. When I attempt to instantiate a component from this library, I get the following error: unable to add archive file: [library].swc$locale\en_US\..\..\resources\images\AcceptButton.png (The system cannot find the path specified) When I unzip [library].swc, the image does exist in .\resources\images\AcceptButton.png as I would expect. Any suggestions to go about resolving this would be much appreciated.

  • Best way to change XIB files based on rotation?

    - by Graeme
    Hi, My app has so far just been a portrait-based application. However, I am adding landscape mode to a new version, but have found that my XIB files look shocking when rotated from portrait to landscape. Apparently I need to make a landscape version of each XIB and use some code to change with XIB launches based on what rotation occurs. Am I right? If so, where do I go from here? Are there any Apple sample apps utilising this code? FYI - My XIB files just have text in them. Thanks.

  • onclick form submit, open jQuery loading image until form submit complete

    - by Jackson
    Hi Team, Can you offer a bit of advice. I am using a hosted SAAS CMS solution that enables you to create basing apps with a web apps system. I have created a form for members to submit a bunch of images and content to their own area. Everything is working great except if the images being submitted via the form are large, it takes ages for the form to submit and go to the thank you page. I am already using jQuery UI to split the form in to 5 steps and using the jQuery facebox plugin for instructional popups. My question is, what would be the best way to display a loading gif (in facebox or in another suggested overlay) while the form is being submitted? Thanks for your help! Jack

  • Visual Web Developer 2005 Express loads very slowly

    - by d03boy
    I admit that I am not a guru of Visual Studio products at all. I am using Visual Web Developer 2005 Express Edition and I'm trying to load someone else's project. This project happens to be a website with many pages. After loading VWD, it asks for a project to open and I select the solution file. It then proceeds to take an extremely long time to load. The status bar indicates that references are being loaded, many of which are in the System.Web.* area it seems. It seems like it's going back and forth between some different packages. The loading time is upwards of 20 to 30 minutes or more. Some others have stated that their projects open fine when they go to File Open Website... and choose the project directory from there. Any ideas what the problem could be and how to fix it? Edit: It finally completed loading after an hour approximately.

  • multiple polls with email submit function

    - by Chris Mousdale
    I want to add a 4 sets of polls that each have around 4 radio buttons each for answers - then i would like to add an 'enter your email address' field below these polls. Finally I would like the submit button after the email field to 'submit' the data from the polls and the email address entered - so only one submit button. Just to make things even better, I would like some form of validation, that will not pass the form unless all 4 polls have a radio button pressed and a valid email. All this is then to go into a MySQL database. I have the email validation bit nailed - so thats fine.. it's the multiple polls bit thats getting me - I cannot get it to work?! Do i have to effectively add 5 forms? Any help would be greatly appreciated.
