  • Is there a "concise" way to do namespacing in JavaScript?

    - by olliej
    I've frequently encountered sites that put all of their javascript inside a "namespace" structure along the lines of namespaces = { com : { example: { example.com's data} } But setting this up safely with respect to other namespaced frameworks seems to require a relatively hefty amount of code (defined as 2 lines). I was wondering whether anyone knows of a concise way to do this? and whether there's a relatively standard/consistent way to structure it? eg. is the "com" namespace directly attached to the global object, or is it attached through a namespace object? [Edit: whoops, obviously {com = { ... } } wouldn't accomplish anything close to what i intended, thanks to Shog9 for pointing that out. :D]

  • Two part form in Rails

    - by samuel02
    I have some two nested resources, so that a Product can have many Bookings. On one page in a different controller I want to create a new booking and since it's a "general" booking I want a select menu to appear in a modal window where the user is able to pick one of the existing products and then go to the booking page. How can I do this? I have no problem setting up the modal and the "New booking" page is already there. What I need is a form that generates a list of existing products, picks the selected product id and then gets /products/:product_id/bookings/new . Any help appreciated! I realize my title does not describe my problem very good so better suggestions are highly welcome!

  • subversioning ipad app project

    - by MistakesRInevitable
    Hi All, I am currently looking at setting up an Ipad app project into subversion. Ive had a lot of experience with windows based development and .net. With this we have just created a repository in a network folder (by just right clicking - TortiseSVN - create repository) , than all we have done is our developers have checked out from this directory. How do we go about doing this in xcode. I know subversion is integrated with xcode and I am pretty confident of doing everything (from tutorials) except for the creation of the repository. Just wondering how we go about creating a repository in a folder based up on network folder? Thanks in advance

  • How to set credential persistence permanent on Android

    - by doreamon
    My app has save login credential feature, so I store cookies for the next use after succeeding to sign in. However, after a time period, the session will be time out and cannot log in with the cookies any more. On iOS, after setting credential persistence to permanent, the app works nicely even after restarting the phone: [[challenge sender] useCredential:[NSURLCredential credentialWithUser:username password:password persistence:NSURLCredentialPersistencePermanent] forAuthenticationChallenge:challenge]; On Android, I cannot find out such kind of this option. Here is from my HttpHelper class: ((AbstractHttpClient) HttpHelper.client).getAuthSchemes().register("ntlm",new NTLMSchemeFactory()); NTCredentials creds = new NTCredentials(user, pass, "", domain); ((AbstractHttpClient) HttpHelper.client).getCredentialsProvider().setCredentials(AuthScope.ANY, creds); The server is SharePoint so I have to deal with ntlm authentication by following this instruction If you have idea, please let me know. Thank you.

  • Sharing folders with VirtualBox, Win7 Host and Ubuntu 9.10 Guest [closed]

    - by user225890
    I have a development setup from this tutorial: http://www.sitepoint.com/blogs/2009/10/27/build-your-own-dev-server-with-virtualbox/ But what I can't figure out is how to share a folder on my Ubuntu virtualized machine with the host Win7. I want to use a Windows text editor to edit code that's on my Ubuntu server. I've tried using the Shared Folders setting, adding "/var/www" but it says that the path is not absolute. When I click on "other", it only allows me to browse folders on my Win7 host. Both the host and guest are 64-bit OS. Thanks in advance!

  • mysql_query( "CALL... multiple results

    - by bradenkeith
    I am tapping into a service that provides zip codes tax information - there service is a bit shakey, so I want to copy their database over and run the results off my own server while using their service to just update my table. However I'm not sure I'm able to loop through multiple results with this query: mysql_query( "CALL zip2tax.z2t_lookup('" . $strZipCode . "','" . $strUserName . "', '" . $strUserPassword . "')" ) I've tried setting $strZipCode to *. However I get an error from the database. I read on MySQL that mysql_next_result should be the solution, however I'm unsure how to properly implement that.

  • one-liner if statements...

    - by snickered
    Total noob here so be gentle. I've looked everywhere and can't seem to find the answer to this. How do I condense the following? if (expression) { return true; } else { return false; } I can't get it to work since it's returning something vs. setting something. I've already seen things like this: somevar = (expression) ? value1 : value2; Like I said, please be gentle :)

  • Django logging in and out - doesn't work if prepend_www set

    - by ropz
    I'm a Django beginner. My site - let's call it abc.com - works fine, letting users log in and out (having originally registered via Django registratiaon). If it's relevant, my virtuahosts file has ServerName abc.com and ServerAlias www.abc.com directives. I don't want my visitors to sense that both abc.com and www.abc.com exist, and so discovered Django's prepend_www setting, which works as intended. In addition to working as intended, however, there's a side effect that disables logging in and out when visiting the www. variant of my site.

  • Java concurrency - Should block or yield?

    - by teto
    Hi, I have multiple threads each one with its own private concurrent queue and all they do is run an infinite loop retrieving messages from it. It could happen that one of the queues doesn't receive messages for a period of time (maybe a couple seconds), and also they could come in big bursts and fast processing is necessary. I would like to know what would be the most appropriate to do in the first case: use a blocking queue and block the thread until I have more input or do a Thread.yield()? I want to have as much CPU resources available as possible at a given time, as the number of concurrent threads may increase with time, but also I don't want the message processing to fall behind, as there is no guarantee of when the thread will be reescheduled for execution when doing a yield(). I know that hardware, operating system and other factors play an important role here, but setting that aside and looking at it from a Java (JVM?) point of view, what would be the most optimal?

  • Opengl ES and texcoord

    - by viraptor
    Hi, I've got some code which I would like to translate into Opengl ES. I'm not experienced with it however, so here it goes. The original code does a loop like this: glBegin(GL_TRIANGLES); for(i=0; i<num_triangles; i++) { glNormal(...); glTexCoord2f(...); glVerted3fv(...); glTexCoord2f(...); glVerted3fv(...); glTexCoord2f(...); glVerted3fv(...); } glEnd(); So that's ok - I can change the vertex handling for each triangle in the loop, into the standard: glEnableClientState (GL_VERTEX_ARRAY); glVertexPointer (3, GL_SOMETHING, 0, verts); glDrawArrays (GL_TRIANGLES, 0, 3); But how do I add the texcoord setting into this example?

  • maintain formatting entered into an html form?

    - by NickG77
    Im setting up a web form, and I'm trying to have it where visitors can paste their resumes into a text area. Then I want to email the info using php mail(). But the resume info is just stored in the variable as one long string with no formatting. Is there a way I can send the pasted resume text to the client in the resume format? Maintaining all the line breaks and stuff? He wants to avoid having people upload resumes.

  • Fastest method for SQL Server inserts, updates, selects

    - by Ian
    I use SPs and this isn't an SP vs code-behind "Build your SQL command" question. I'm looking for a high-throughput method for a backend app that handles many small transactions. I use SQLDataReader for most of the returns since forward only works in most cases for me. I've seen it done many ways, and used most of them myself. Methods that define and accept the stored procedure parameters as parameters themselves and build using cmd.Parameters.Add (with or without specifying the DB value type and/or length) Assembling your SP params and their values into an array or hashtable, then passing to a more abstract method that parses the collection and then runs cmd.Parameters.Add Classes that represent tables, initializing the class upon need, setting the public properties that represent the table fields, and calling methods like Save, Load, etc I'm sure there are others I've seen but can't think of at the moment as well. I'm open to all suggestions.

  • An explanation of memory usage on Windows server 2003

    - by Rich
    Hi, We've been working on a bit of puzzle at work. We have an application service installed on two machines, both running Windows server 2003. These services do exactly the same thing. However once loaded, one of the services uses 200mb less than the other service. We're at a bit of a loss to what might be causing this discrepancy. I was wondering if there was some kind of server setting that would cause an application to use more memory (heap block size) or anything to explain this. If anyone has any ideas on what may be causing this, or how to find out what is causing this I'd be very grateful. Cheers Rich

  • 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

  • Preventing the "[YourProgramName] has stopped working" dialog on unhandled exceptions.

    - by Serapth
    I have a WinForm application, with some dependencies on an external library that can on occasion cause an exception outside of the running threads context. As it stands now, this is completely OK behavior ( well, except of course the exception ) and we wired up AppDomain.CurrentDomain.UnhandledException to simply restart the program. The only problem is, the [Your Program] has stopped working like the one below, appears: Is there a way to prevent this dialog from appearing at all, be it in the AppDomain unhandled exception handler or in a config setting, as no end users are going to be reading it and it just holds up resources until it is clicked.

  • Application Role and access second database

    - by lszk
    I have written a script to create an audit trails to my database in a second one db. So far I had no problems during tests on my dev machine from SQL Server Management Studio. Problems started to occurs when I first tried to test my triggers from my application by modyfing data in it. Using profiler I found out, that my audit trails db is not visible in sys.databases, so here lies the problem. The application using an Application Role, so as I found on MSDN, that's why I can't get access to other db on the server. I'm not a DBA. I have no experience with properly settings the security stuff, so please guide me, how can I set the setting for guest account (according to MSDN) to get access to this db? I need to have a record for this database in sys.databases and I need to be able to insert data in this database in all tables. No select, update or delete I need.

  • How do I change the background image of my app?

    - by user356387
    Hello I have looked around and found some code which so called chooses an image from an array of image objects, but cant find an explanation. I would like to make my app have a background image and the user can select next and previous buttons to scroll through some full screen images, setting them as the background image as they scroll. I know how to do this in java, but cant seem to do it for this app. How or what code is linked to a next button to grab the next image in the array and reverse for the back button? Then that needs to be displayed obviously. I have used a layered architecture with a MVC style approach but cant seem to put it together with Objective-C. Would the buttons call the appropriate methods of the so called delegates, which the delegates handle fetching and returning the Images? Would the buttons use the returned images and actually handle the redrawing? I would really appreciate the help. Regards Jarryd

  • Hibernate criterion Projection alias not being used

    - by sbzoom
    Do Hibernate Projection aliases even work? I could swear it just doesn't. At least, it doesn't do what I would expect it to do. Here is the java: return sessionFactory.getCurrentSession().createCriteria( PersonProgramActivity.class ).setProjection( Projections.projectionList().add( Projections.alias( Projections.sum( "numberOfPoints" ), "number_of_points" ) ).add( Projections.groupProperty( "person.id" ) ) ).setFirstResult( start ).setFetchSize( size ).addOrder( Order.desc( "numberOfPoints" ) ).list(); Here is the SQL that it generates: select sum(this_.number_of_points) as y0_, this_.person_id as y1_ from PERSON_PROGRAM_ACTIVITY this_ group by this_.person_id order by this_.number_of_points desc It doesn't seem to use the alias at all. I would think setting the alias would mean that "sum(this_.number_of_points)" would be aliased as "number_of_points" and not "y0_". Is there some trick I am missing? Thanks.

    - by atodd
    I'm trying to setup a dual boot system with Windows Vista 64 (already installed) and Ubuntu 10.10. I added a new drive which is identical to the one Vista is installed on. When I boot into the LiveCD I can see and mount the second drive and edit it in Gparted. However, when I use the installer it will only bring up the drive that already has Vista installed. I've tried everything I know. I'm not sure if its a BIOS setting or something else I've missed.

  • Do not want Form to display over other application windows

    I am displaying a Form from one process by passing the Show method a window handle from another process. I only want this new Form to display above the passed Form, like a MessageBox. However, this newly launched Form appears above other application windows, despite: Setting Process.WindowStyle.Hidden to the Form-displaying process Overriding the ShowWithoutActivation and CreateParams properties of the Form. Making sure Form.TopMost is not true I have checked that the window handle is valid from the second process. Focus is not stolen, however. Process A: Pass (Form) window handle to a new Process B via the command line Process B: Display a new Form using Form.Show(anotherProcessWindowHandle)

  • PivotControl item changing behavior in Silverlight Windows Phone 7

    - by Rosarch
    I have an app where the user is sent to a page with a PivotControl. The SelectedIndex is not known until the user navigates to the page. I'm setting the SelectedIndex, but it causes the PivotControl to start on index 0, then flip through to the index I set. This is kind of annoying, and I'd rather just have it go directly to the index I set. Is there some way around this? One hack I thought up was providing the data to pivotControl.ItemsSource in an order such that the item I want the user to start on is index 0 in ItemsSource. But that would be kind of messy, and I'm wondering if there's a more elegant solution.
