  • integrating facebook auth into my web form app

    - by user169692
    Hi, I would like to allow my users to authorise my app with their fb on registration. All of the examples i see redirect users to the fb canvas page after authorisation, but i only want this to be a step in the registration process. Essentially, i want an icon they can click that would open up a new window where they can login to fb and a simple postback to the registration page where i would detect the login and hide the login button. Any ideas on how I can achieve this using the facebook c# sdk? Thanks and Merry Christmas :)

  • UnicodeDecodeError from a GET-parameter in webapp2

    - by Aneon
    I'm getting a UnicodeDecodeError when recieving a GET-parameter from webapp2 that contains unicode characters, and then using it to do a NDB query. I get the same error message when manually running a unicode() on the parameter in the handler, so there either seems to be a problem in webapp2's URL routing or I've missed something. Preferably, all GET-parameters should be converted to unicode before getting passed into the handler so I don't need to do manual conversions in all of my handlers. I actually think it's worked before in an earlier version. The full error message read: UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 1: ordinal not in range(128) The GET-parameter contains the following string: göteborg. It looks fine when I raise an Exception on it, but gives me an error when I (or NDB) use unicode() on it. EDIT: In NDB, it fails on the following code: File "C:\Program Files (x86)\Google\google_appengine\google\appengine\api\datastore_types.py", line 1562, in PackString pbvalue.set_stringvalue(unicode(value).encode('utf-8')) Thanks.

  • Quick to develop web app in Java

    - by Mike Q
    Hi all, I need to develop a basic web app very quickly (1 week) for a demo. My requirements are Java (I need to make use of existing Java libraries to access the relevant data) 2 screens One for static data view, maybe some search parameters Other for basic form entry No fancy AJAX required Ideally easy for a web designer to come in and tart it up as necessary, without having to rewrite everything My first stop was going to be to checkout Wicket as I've heard good things about it. I don't have the time right now to dive into anything heavy, which probably writes off JSF in my mind (I played with JSF1, steep learning curve which I've now slid back down). I'm happy to treat the result as throwaway so if there's a framework which starts of well but then doesn't scale up to bigger projects, that would be ok. Any suggestions appreciated on frameworks/approach.

  • Background audio not working in windows 8 store / metro app

    - by roryok
    I've tried setting background audio through both a mediaElement in XAML <MediaElement x:Name="MyAudio" Source="Assets/Sound.mp3" AudioCategory="BackgroundCapableMedia" AutoPlay="False" /> And programmatically async void setUpAudio() { var package = Windows.ApplicationModel.Package.Current; var installedLocation = package.InstalledLocation; var storageFile = await installedLocation.GetFileAsync("Assets\\Sound.mp3"); if (storageFile != null) { var stream = await storageFile.OpenAsync(Windows.Storage.FileAccessMode.Read); _soundEffect = new MediaElement(); _soundEffect.AudioCategory = AudioCategory.BackgroundCapableMedia; _soundEffect.AutoPlay = false; _soundEffect.SetSource(stream, storageFile.ContentType); } } // and later... _soundEffect.Play(); But neither works for me. As soon as I minimise the app the music fades out

  • Read Core data in Serial Queue for iPhone app

    - by user1277209
    I have an app which uses Core data and the values are fetched from a link on internet. This runs absolutely fine when I am creating a serial queue in AppDelegate and I am not facing any problem with the same. Now, when I am trying to re-create similar scenario in a UITableViewController and executing the same in a serial queue but when the control reaches NSError *error; NSArray *match = [context executeFetchRequest:fetchRequest error:&error]; execution control disappears and then this code remains in the execution till eternity. Can anyone help me with what exactly is wrong here? FYI, I am passing the same ManagedObjectContext to the serial queue.

  • Decoding international chars in AppEngine

    - by Irro
    I'm making a small project in Google AppEngine but I'm having problems with international chars. My program takes data from the user through the url "page.html?data1&data2..." and stores it for displaying later. But when the user are using some international characters like åäö it gets coded as %F4, %F5 and %F6. I assume it is because only the first 128(?) chars in ASCII table are allowed in http-requests. Is there anyone who has a good solution for this? Any simple way to decode the text? And is it better to decode it before I store the data or should I decode it when displaying it to the user.

  • How to use ';' in urls, using Google Appengine

    - by tonfa
    Using the local dev server, I can use ';' in urls, but as soon as I try the live version hosted by Google, it looks like the ';' and everything afterward is stripped (at least according to request.path_qs). (I would prefer not to encode them if possible, it's much less user friendly if the url cannot be constructed by copy-pasting, especially since other characters works fine, e.g. ':').

It displays: This web site needs a different Google Map API key. A new key can be generted at http://code.google.com/apis/maps/. Sorry but I've never used this application before. Do I have to just generate a new code in order to solve the problem? Or there are another problems?

  • Silverlight app doesn't access web over WCF in IIS

    - by S.Amani
    Hi, My application SilverLight which is hosted in my local host, doesn't access my web app and its database over WCF. I don't know why !!. I've looked over 100 sites and blogs which they have scribed how to configure WCF in IIS, but I can't fix my problem. Note : I debugged it with fiddler in my localhost, everything just worked fine, I saw all my site transaction, except a button which is responsible to access Data over WCF, fiddler didn't log that. Any advice will be helpful. Best Regards SABER.

  • Extend Google AppEngine User in JRuby?

    - by Ryan Montgomery
    I'm working with JRuby and DataMapper running on Google AppEngine. I want to add a property to the AppEngine::User like :active_calendar which is a reference to a Calendar kind. I was able to do something in Python this way using a back reference. Are these possible in JRuby? Is this possible? Do I need to subclass the User? Can I even do that? If so - how? Thanks!

  • Appengine backreferences - need composite index?

    - by davezor
    I have a query that is very recently starting to throw: "The built-in indices are not efficient enough for this query and your data. Please add a composite index for this query." I checked the line on which this exception is being thrown, and the problem query is this one: count = self.vote_set.filter("direction =", 1).count() This is literally a one-filter operation using appengine's built-in backreferences. I have no idea how to optimize this query...anyone have any suggestions? I tried to add this index: - kind: Vote properties: - name: direction direction: desc - kind: Vote properties: - name: direction And I got a message (obviously) saying this was an unnecessary index. Thanks for your help in advance.

  • ASP.NET null reference exception

    - by nanek
    Please help me to figure out what is wrong with this code: I have ASP.NET page with one button visible. When user clicks it - it instances MyClass (its implementation is in AppCode directory) and turns invisible (button2 becomes visible). When I click button2 it raises "Object reference not set to an instance of an object" Exception. What seems to be the problem? { public MyClass noviTest; protected void Page_Load(object sender, EventArgs e) { } protected void Button1_Click(object sender, EventArgs e) { noviTest = new MyClass(TextBox1.Text); Button1.Visible = false; Button2.Visible = true; } protected void Button2_Click(object sender, EventArgs e) { Label1.Text=noviTest.getID; //this is the critical line } } Thank You in advance, Regards

  • Which web solution should I use for my project?

    - by BenIOs
    I'm going to create a fairly large (from my point of view anyway) web project with a friend. We will create a site with roads and other road related info. Our calculations is that we will have around 100k items in our database. Each item will contain some information like location, name etc. (about 30 thing each). We are counting on having a few hundred thousand unique visitors per month. The 100k items and their locations (that will be searchable) will be the main part of the page but we will also have some articles, comments, news and later on some more social functions (accounts, forums, picture uploads etc.). We were going to use Google AppEngine to develop our project since it is really scalable and free (at least for a while). But I'm actually starting to doubt that AppEngine is right for us. It seems to be for webbapps and not sites like ours. Which system (language/framework etc.) would you guys recommend us to use? It doesn't really mater if we know the language since before (we like learning new stuff) but it would be good if it's something that is future proof.

  • Unit testing task queues in AppEngine

    - by Swizec Teller
    For a very long time now I've been using task queues on AppEngine to schedule tasks, just the way I'm supposed to. But what I've always been wondering is how does one write tests for that? Until now I've simply made tests to make sure an error doesn't occur on the API that queues a task and then wrote the more proper tests for the API executing the task. However lately I've started feeling a bit unsatisfied by this and I'm searching for a way to actually test that the correct task has been added to the correct queue. Hopefully this can be done better than simply by deploying the code and hoping for the best. I'm using django-nonrel, if that has any bearing on the answer. To recap: How can a unit test be written to confirm tasks have been queued?

  • ODBC - multiple connections from one app to the same data source

    - by Marcin K
    I vaguely remember reading somewhere (in MSDN ODBC documentation?) that one application cannot make more than one connection to a single data source. It seemed to me that I need one connection that all the threads of the application will have to share. I was trying to look this information up, but I can't seem to find it anymore. Does anyone know/remember how this works? It all might become a problem in our app, since some of its threads will dynamically connect to data sources of their choice. I don't want to see random connection errors if two of them will connect at the same time to one source, so I wanted to double check this info.

  • App disappears from Win7's ALT-TAB list sometimes

    - by Mason Wheeler
    I've been having some trouble with one of my Delphi 2010 projects lately. It seems that sometimes, when I have a form open as a modal dialog, the app stops showing up in the ALT-TAB list until I close the dialog. It's still in the Taskbar, but not in ALT-TAB, which means I can't switch to it without using the mouse. Running under Windows 7, 64-bit. Has anyone seen this before? Any idea what causes it and how to fix it?
