• how to fetch app data(name, version, etc.) from android market?

  - by liuxingruo

  As we know, the apps in the apple app store has a unique itunes link, and we can fetch app data about the app from app store through the link. I am wondering how can i achieve this in the android market, just like the website http://www.androlib.com/ did? As long as I know, each app in the android market has a ID, which just like "com.gabrouze.magic", and the QR Code can be viewed in "http://chart.apis.google.com/chart?cht=qr&chs=135x135&chl=market://search?q=pname:com.gabrouze.magic". Thanks!

• Lazy loading of ESB in a jruby rails app

  - by brad

  I have a jruby/rails app using: jruby 1.4.0 Rails 2.3.5 ActiveMQ 5.3.0 Mule ESB 2.2.1 Currently in our environment.rb file we start up Mule in the initializer. This becomes a big pain when we go to do normal rake tasks that don't require JMS/Mule such as db:migrate as it takes a long time to startup/shutdown Mule everytime. The code is similar to this: APP_CONTEXT = Java::our.company.package.service_clients.Initializer.getAppContext(MULE_CONFIG_PATH) And we use APP_CONTEXT to fetch the bean to connect to the appropriate service. I'm trying to figure out some mechanism by which APP_CONTEXT could be lazily instantiated (not in initialize) to avoid all of the pains of having to startup Mule on initialize. Currently we have a few ruby client classes that are instantiated as a before_filter in application_controller such as @data_service = DataService.new(APP_CONTEXT) that initialize the proper java client for each request for use in our controllers. I'm open to all suggestions. I'm having a hard time trying to find the right place to put this lazy instantiation.

• Concerns about reading a file in Flash 10

  - by user246114

  Hi, I'd like to read an xml file on a user's machine (which can be kind of large). There's no point in me sending the file to my server as I can do all the work I need on the file right on the client's machine. Not sure if this is a good fit though, was wondering if anyone can answer these questions before I dive in: I see at adobe's website that Flash 10 has like 94% penetration, is this true, I thought it was just released not too long ago? After opening the xml file in flash, is it possible to just throw it to a javascript function on my same page for further processing? I'd like to go into flash world for as short a time as possible. Is it at all common to use flash for file upload stuff? I heard aol/flickr are? I would need to buy flash in order to do this right, they don't have a free ide/compiler yet? Thanks

• How can I enable Pascal casing by default when using Jackson JSON in Spring MVC?

  - by bhilstrom

  I have a project that uses Spring MVC to create and handle multiple REST endpoints. I'm currently working on using Jackson to automatically handle the seralization/deserialization of JSON using the @RequestBody and @ResponseBody annotations. I have gotten Jackson working, so I've got a starting point. My problem is that our old serialization was done manually and used Pascal casing instead of Camel casing ("MyVariable" instead of "myVariable"), and Jackson does Camel casing by default. I know that I can manually change the name for a variable using @JsonProperty. That being said, I do not consider adding "@JsonProperty" to all of my variables to be a viable long-term solution. Is there a way to make Jackson use Pascal casing when serializing and deserializing other than using the @JsonProperty annotation?

• Page Footer not showing in Crystal Report

  - by Mike C.

  Hello, I am using Crystal Reports in Visual Studio 2008. I have about 5 pages worth of static text that needs to appear at the top of my report, so I put it in the report header section. I have a page footer section on the page that shows the page number. This does not show, and I suspect it has something to do with the long report header. How can I make the page footer show with a large report header? Edit: The Page Footer is actually appearing once on the last page. The Report Header takes up 5 pages and there isn't a page footer on any of those pages.

• Why "Algorithms" and "Data Structures" are treated as separate disciplines?

  - by Pavel Shved

  This question was the last straw; and I've been wondering for a long time about it, Why do people think about "Algorithms" and "Data structures" as about something that can be separated from each other? I see a lot of evidence that they're separated in programmers' minds. they request "Data Structures & Algorithms" books they refer to "Data Structures" and "Algorithms" as separate university courses they "know Algorithms", but are "weak in Data Structures" (can't find the link, sorry). etc. In my opinion "Data Structures" are algorithms, since the concept of "Data Structure" is about Algorithms to operate data that go in and out of the structures. But the opinion seems not a mainstream. What do I miss?

• Objective-C : Trouble with file download

  - by Holli

  I ran in a bit of trouble downloading files with Objective-C. I use the download decideDestinationWithSuggestedFilename from Apples documentation page. http://developer.apple.com/mac/library/documentation/cocoa/conceptual/URLLoadingSystem/Tasks/UsingNSURLDownload.html As long as I want to download just one file it works fine but I want to download an array for files one by one. The problem starts with the second file. Right now my code will trigger the next download itself from the downloadDidFinish Method. Then I will get an unrecognized selector sent to instance error. For me it looks like the NSURLDownload that just finished the download is still in use somehow. Release is called but the must be a problem. If I just put an NSBeep in the downloadDidFinished Method and trigger the next file download manually it works fine. Looks like I have to wait a while till I can start the next download. I know this question is a bit vague but maybe someone got an idea.

• Best Practices - Stored Procedure Logging

  - by hgulyan

  If you have a long running SP, do you log somehow it's actions or just wait for this message? "Command(s) completed successfully." I assume, that there can be plenty solutions on this subject, but is there any best practice - a simple solution that is frequently used? EDIT I've found an interesting link on this subject http://weblogs.sqlteam.com/brettk/archive/2006/09/21/12391.aspx Article describes using a log table, but there's an issue The logging procedure must be executed outside of any transaction I can't call that insert outside, because of cursor that I use and insert a line to that table on every row. Any ideas?

• Efficiently check string for one of several hundred possible suffixes

  - by Ghostrider

  I need to write a C/C++ function that would quickly check if string ends with one of ~1000 predefined suffixes. Specifically the string is a hostname and I need to check if it belongs to one of several hundred predefined second-level domains. This function will be called a lot so it needs to be written as efficiently as possible. Bitwise hacks etc anything goes as long as it turns out fast. Set of suffixes is predetermined at compile-time and doesn't change. I am thinking of either implementing a variation of Rabin-Karp or write a tool that would generate a function with nested ifs and switches that would be custom tailored to specific set of suffixes. Since the application in question is 64-bit to speed up comparisons I could store suffixes of up to 8 bytes in length as const sorted array and do binary search within it. Are there any other reasonable options?

• JPA @TableGenerator shared between multiple entities

  - by Mauricio

  Hi Guys, I have a 'dog' Entitiy with an @Id and a @TableGenerator ... @TableGenerator(table = "seq", name = "dog_gen", pkColumnName = "seq_name", valueColumnName="seq_val") @Id @GeneratedValue(strategy = GenerationType.TABLE, generator = "dog_gen") private Long id; ... Is there a way to reuse the same table generator (dog_gen) in other entity? I want to keep the same id sequence in two independent Entities, say dog=1, dog=2, dog=3, cat=4, cat=5, dog=6 and so on... Both entities don't share a common superclass to implement some kind of inheritance with the id property. If I add the @GeneratedValue( generator="dog_gen") on my cat entity, omitting the @TableGenerator declaration throws an Exception saying it can't find the generator when starting the context. Caused by: org.hibernate.AnnotationException: Unknown Id.generator: dog_gen at org.hibernate.cfg.BinderHelper.makeIdGenerator(BinderHelper.java:413) at org.hibernate.cfg.AnnotationBinder.bindId(AnnotationBinder.java:1795) at org.hibernate.cfg.AnnotationBinder.processElementAnnotations(AnnotationBinder.java:1229) at org.hibernate.cfg.AnnotationBinder.bindClass(AnnotationBinder.java:733) at org.hibernate.cfg.AnnotationConfiguration.processArtifactsOfType(AnnotationConfiguration.java:498) at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:277)

• Question about function returning array data

  - by Doug

  var grossBrackets = new Array( '300', '400', '500', '600', '700', '800', '900', '1000' ); function bracketSort( itemToSort ) { for( index = 0 ; index < grossBrackets.length ; index++ ) { if ( itemToSort < grossBrackets[index] ) { bracketData[index]++; } else if ( itemToSort > grossBrackets[7] ) { grossBrackets[7]++; } } return bracketData; } This is my current code, and I basically want to sort the data into their proper brackets. My source code is really long, but when I input these numbers into the function: 200.18 200.27 200.36 200.45 200.54 bracketData prints 5,5,5,5,5,5,5,5 or is there a better way to do this? Brackets: <300, <400, <500, <600, <700, <800, <900, <1000, greater than 1000

• How to capture any key in X?

  - by cz-david

  Hi, I am building an application for which I need to periodically get information about users keyboard. It is going to be user idle detection application. I have a fairly simple solution to periodically check if the mouse has been moved. But I can't figure any reasonable non root way to detect if the keyboard has been pressed. I was thinking about registering a hook every timer timeout and on any key press to unregister it. So if there is no key press for a long time then my program will know if the user is idle. Anyway, I couldn't find any global hooks for any key, including modifiers. Is there an easy way to do this? Or would someone have a better way to detect keyboard idleness? Thanks, David Polák

• Cufon delay in WordPress, Mac/Safari/FF...

  - by luke

  Using cufon 'manually' not the plugin.... I have a delay on many page loads in Safari and FF on the Cufon enabled headings.... http://www.budewebdesign.com/haf Tried moving Cufon higher up (eg before wp_head() and the plugin code that calls, without any real effect. Some pages no problem but others just a long enough delay to be annoying. I'm not really keen on hiding the headings before the page load completes as is suggested elsewhere. If it loads without delay some of the time, I wonder if it can be made to 'all' of the time :) My connection speed is good. Thanks for any ideas on this.

• How2 display Image from DB in datagrid?

  - by Saverio Tedeschi

  Hope it's not yet been answered, but I've googled for quite a long time, and I've not been able to get it working. In brief, I've a SL4 page with a DataGrid filled accordingly to parameters passed from the previous page, so I fill the context in code, with a "RIA" query (w/parameters as well). So far, so good. I get the XAML declared columns as expected but the Photo templated column, which holds just an image control. I think I can use the LoadingRow event, but can some1 give me some code on how to get my goal (image is in in the context from DB)? Thanks in advance

• Mapview getLatitudeSpan and getLongitudeSpan not working

  - by janfsd

  Hi! Sometimes when trying to get the Latitude span or Longitude span of a mapview with getLatitudeSpan() and getLongitudeSpan() I get 0 and 360*1E6 respectively. This doesn't happen always but it is a problem, has anybody got this problem? Any workarounds? I tried using getProjection() too but I get the same problem. Here is the piece of code: MapView mapView = (MapView) findViewById(R.id.mapview); int lat = mapView.getLatitudeSpan(); // sometimes returns 0 int long = mapView.getLongitudeSpan(); // sometimes returns 360*1E6

• EXC_BAD_ACCESS signal received

  - by Hector Ramos

  When deploying the application to the device, the program will quit after a few cycles with the following error: Program received signal: "EXC_BAD_ACCESS". The program runs without any issue on the iPhone simulator, it will also debug and run as long as I step through the instructions one at a time. As soon as I let it run again, I will hit the EXC_BAD_ACCESS signal. In this particular case, it happened to be an error in the accelerometer code. It would not execute within the simulator, which is why it did not throw any errors. However, it would execute once deployed to the device. Most of the answers to this question deal with the general EXC_BAD_ACCESS error, so I will leave this open as a catch-all for the dreaded Bad Access error. EXC_BAD_ACCESS is typically thrown as the result of an illegal memory access. You can find more information in the answers below. Have you encountered the EXC_BAD_ACCESS signal before, and how did you deal with it?

• Entire website in Silverlight 4. Practical or not?

  - by Sahat

  Similar question: Using Silverlight for an entire website? That question is over 2 years old. Silverlight has gone a long way from Silverlight 1.0 Beta 1 to Silverlight 4.0 Final. Would it be practical to create a full Silverlight web application these days? I plan to deploy the website sometime around Q1 2011. I have thought about going ASP.NET + AJAX way, but it just won't give me the same rich features as Silverlight. A lot of people when they hear ASP.NET or Silverlight instantly think about business or enterprise applications. But all I want to create is a fansite, with rich user interface and a great "WOW" factor.

• How does one change the background color for a loading out-of-browser Silverlight 3 application?

  - by Jacob

  When running our Silverlight 3 application out-of-browser, startup takes a little time, but it's long enough to be noticeable. During this startup, the background of the window hosting the application displays an ugly white background color. When running in-browser, we have a splash screen, but that's loaded via JavaScript of course. How can I get a splash screen working for an out-of-browser Silverlight 3? Or if that's not possible, is there a way I can at least change the background color of the window?

• On iPhone, how do I show a login screen to get username and password before giving access to iPhone

  - by MikeN

  On iPhone, how do I show a login screen to get username and password before giving access to iPhone app? Also, does the iPhone store a cookie to the secure website like a web browser? I was thinking of giving users to my website a long API key to store in the settings of their iPhone instead of asking them to login with a username/password (seems to be the Slicehost iPhone app approach.) Which is the best way to get a user to login securely? I have full control over the design of the iPhone app and website so have a lot of flexibility.

• Problem with Access 2003 linking tables with SQL Server 2008 using ODBC

" 'Pk_dbo.Batch_Claims' is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not to long. " Pk_dbo.Batch_Claims is the key value I see when looking at the table through SSMS. I have used Access for awhile but am somewhat new to SQL Server and connections using ODBC. Any help would be appreciated. Thanks
