  Hi. I'm planning to develop kind of DJ application which loads musics from music library. And of course it'll sell in app store. So question is, does it possible distribute in AppStore? I found it was forbidden at least about 6 month ago... But I hope it is possible now...

• Does android support playlists for video files?

  - by DanJ

  I'm and android beginner, so go easy on me ;-) I'm trying to play a sequence of video files which I'm downloading from a server. The challenge is that I want to have a smooth transition from one file to another. My thought is to have two MediaPlayer instances each preparing and then playing in turn. It is not clear to me if they can both share the same SurfaceView? Or maybe, I should be using different views and swapping between them? Or, the idea is a bad idea all together? When I try to run configure the MediaPlayer instance with a view that isn't visible it seems to crash my emulator.

• Any experiences using SharpDevelop to build an ASP.NET MVC app?

  - by Sosh

  I've always used VS for .NET development, but am just wondering about the alternatives around now. I'm especially interested in use for ASP.NET MVC development. I'm not bothered about any of the visual design aspects of vs, but of course love intellisense and the debugging features. So, for anyone who has tried SharpDevelop when doing ASP.NET MVC: How did you get on? What are the main disadvantages and pain points? Thanks

• Ultimate chat-client API for .NET?

  - by Shimmy

  Does anyone know of a .NET API (source-code is preferrable of course) that I can access all the common chat clients thru it (GT, Yahoo, MSN, AIM, FB, ICQ, SKYPE and more)? I guess I am looking for a .NET library project that performs something like pidjin. I need it because I hate Pidgin's interface and functionality, and I want to have a Google-Talk desktop like UI. Any comments and tips will also be very useful. Thanks.

• How can I test when a feature was added to Perl?

  - by Eric Strom

  Are there any services similar to codepad that will allow you to test Perl constructs on old versions of perl? Ideally, a system where you could enter an expression and it will tell you the oldest version of perl that it will work with. Of course it's possible to use CPANTS for this, but that seems like an abuse of the service (if only for making the BackPan bigger). And it could take several days/weeks to get decent test coverage on old versions.

• iPhone image app not releasing memory as in instruments using imageNamed

  - by Tankista

  hi, im building iPhone app that downloads images (UIImageView) from internet and adding them to UIScrollView. This scroll view could contain 20 or more UIImageViews. Iam adding UIImages to UIImageView like this: UIImageView *newView = [[UIImageView alloc] initWithImage: image]; Then I just scroll these images like in photo app. Problem is, when I put just 3 UIImageViews in UIScrollView everything works fine, but when I put more images, more memory is used, so that app can crash after 15 or more images. I can understand it that more images alloc more memory, but in Instruments i get allocated max 2-3 MB, but in device memory raises until it crashes. When I use simulator for OS 3.0 i can see memory rising like on device. On higher versions I dont see this memory raise, why is that?

• Is there good .sol editor for Flash Player 9 Local Shared Objects? Can we build one?

  - by nerdabilly

  There's plenty of them out there but none of them do what I would like them to do. Most of them crash when opening a file or simply corrupt the data. Many don't run at all. It seems to me that most were written 3-4 years ago for AS2 .sols and no longer work with FP9/AS3 sols. I'd attempt to write my own using AIR but I can't find a new spec of the byte format. There's an explanation of the file format here: http://sourceforge.net/docman/display_doc.php?docid=27026&group_id=131628 and another here: http://sourceforge.net/docman/display_doc.php?docid=27026&group_id=131628 but it looks as though both of these docs are a good 4 years old (pre-FP9) and as I'm not skilled or experienced in file formats, writing a new one, especially without an updated spec, is seeming like less and less of a viable option. Ideally I'd like one that can not only read the .sol, but edit and save new values also. Thanks!

• Using jQuery live() to initialize plugins?

  - by cxfx

  Using jQuery, what's the best way to automatically initialize a plugin on all current and future elements of a specific class? For example, say I want all <input type="text" class="datepicker" /> elements to have the jQuery UI Datepicker plugin, including any I might create at runtime. Essentially, I want to do something like this: $('.datepicker').live('create', function() { $(this).datepicker(); }); But, of course, there isn't a create event I can use.

• simple yet secure encrypt / decrypt asp to asp.net

  - by Michael

  First post here. I have a asp/vb6 web app that logs in a user I want to encrypt the users identity field and pass(querystring) it to a asp.net app and then decrypt it to do a db lookup. I've google'd it of course and found rot13, not secure enough. I've also found some hits on MD5 / RC4 but did not find any good examples of encrypt / decrypt. Thanks, Michael

• Did you feel learning to program with turtle graphics was useful?

  - by minty

  I'm preparing to teach someone to program. When I learned the course material used turtle graphics for the first few exercises. In reading introductory textbooks I have not found one that uses the technique. Did others find this approach helpful. If not what is a better way to learn to program?

• Adding an HTTP Header to the request in a servlet filter

  - by Mason

  I'm integrating with an existing servlet that pulls some properties out of the HTTP header. Basically, I'm implementing an interface that doesn't have access to the actual request, it just has access to a map of k-v for the HTTP headers. I need to pass in a request parameter. The plan is to use a servlet filter to go from parameter to header value but of course the HttpServletRequest object doesn't have an addHeader() method. Any ideas?

• Inserting clobs into oracle with ODBC

  - by Carra

  I'm trying to insert a clob into Oracle. If I try this with an OdbcConnection it does not insert the data into the database. It returns 1 row affected and no errors but nothing is inserted into the database. It does work with an OracleConnection. However, using the Microsoft OracleClient makes our webservices often crash with an AccessViolationException (Attempted to read or write protected memory. This is often an indication that other memory is corrupt.). This happens a lot when we use OracleDataAdapter.Fill(dataset). So using this doesn't seem like an option. Is there any way to insert/update clobs with more then 4.000 characters from .Net with an OdbcConnection?

• Code review tool for Vault

  - by Miki Watts

  We're using Vault from SourceGear as our source control repository. Does anyone know if there's a code review tool that can work with Vault, or something that can work with local files ? I've checked the related questions, but I didn't see something that works with local files (of course I may have just missed it).

• Dealing with UIImagePickerController to minimize memory useage

  - by Gordon Fontenot

  So, I have read the SO post on UIImagePickerController, UIImage, Memory and More, and I read the post on Memory Leak Problems with UIImagePickerController in iPhone. I have VASTLY increased my memory efficiency between these 2 posts, and I thank the OPs and the people that provided the answers. I just had a question on the answer provided in the Memory Leak question, which was (essentially): only have one instance of the controller throughout the programs runtime What would be the best way to go about this without causing memory leaks? Right now I am initiating it and releasing it on every use from within the view, and I am seeing exactly what the answer describes (Memory warnings and a crash after about 20 uses). Should I initiate the UIImagePickerController when I need it, but use a seperate class unrelated to the view to control it? How should I deal with releasing the controller if I do it this way?

• Detecting a Lightweight Core Data Migration

  - by hadronzoo

  I'm using Core Data's automatic lightweight migration successfully. However, when a particular entity gets created during a migration, I'd like to populate it with some data. Of course I could check if the entity is empty every time the application starts, but this seems inefficient when Core Data has a migration framework. Is it possible to detect when a lightweight migration occurs (possibly using KVO or notifications), or does this require implementing standard migrations? I've tried using the NSPersistentStoreCoordinatorStoresDidChangeNotification, but it doesn't fire when migrations occur.

• Crashing the OS X Pasteboard

  - by Ben Packard

  I have an application that reads in text by emulating CMD-C copy commands and reading the pasteboard - unfortunately this the only way to achieve what I need. Occasionally, something goes wrong in execution (not sure yet if it's related to the copy command or not) and the app crashes. Once in a while, this has a knock on effect on the system-wide pasteboard - any other application that is running will crash if I attempt a copy, cut, or paste. Is there a robust way to handle this - something I should be doing with the NSPasteboard before exiting? Any information on what might be happening is appreciated. For completeness, here are the only snippets of code that access the pasteboard: Reading from the pasteboard: NSString *pBoardText = [[NSPasteboard generalPasteboard]stringForType:NSStringPboardType]; Initially clearing the pasteboard (I run this only once, at launch): [[NSPasteboard generalPasteboard] declareTypes: [NSArray arrayWithObject:NSStringPboardType] owner: self]; [[NSPasteboard generalPasteboard] setString: @"" forType: NSStringPboardType];

• Sanitizing input for display in view when using simple_format

  - by Eric

  Hi, I'm trying to figure out the right way to display comments such that newlines and links are displayed. I know that usually, you should display user-inputs only when escaping html with h(). That of course won't display newlines or links, so I found the simple_format and auto_link methods. What I am now doing is: simple_format(santize(auto_link(comment.text))) Is this the right way to do this, and is it still safe from XSS attacks? Thanks! Eric

• Identify cause of hundreds of AJP threads in Tomcat

  - by Rich

  We have two Tomcat 6.0.20 servers fronted by Apache, with communication between the two using AJP. Tomcat in turn consumes web services on a JBoss cluster. This morning, one of the Tomcat machines was using 100% of CPU on 6 of the 8 cores on our machine. We took a heap dump using JConsole, and then tried to connect JVisualVM to get a profile to see what was taking all the CPU, but this caused Tomcat to crash. At least we had the heap dump! I have loaded the heap dump into Eclipse MAT, where I have found that we have 565 instances of java.lang.Thread. Some of these, obviously, are entirely legitimate, but the vast majority are named "ajp-6009-XXX" where XXX is a number. I know my way around Eclipse MAT pretty well, but haven't been able to find an explanation for it. If anyone has some pointers as to why Tomcat may be doing this, or some hints on finding out why using Eclipse MAT, that'd be appreciated!

• Disable themed Window Border

  - by Jimmie Lin

  In Windows XP's CMD, the Luna border isn't applied to it. Is it possible to do it in a similar way in Visual C# Winforms, for an application? I just wonder how it's done, of course I am not going to force any of my applications to not use the beautiful XP/Aero theme :P Thanks.
