• Jar extraction and verification in BlackBerry

  - by Basilio

  Hi All, The application I am currently working on requires me to extract contents from and verify the authenticity of the signed jar that is stored on the SD Card. In Java [and Android], we have the java.util.jar and java.util.zip classes, that allow to extract jar. However, J2ME or BlackBerry® does not provide support for these packages. I have, however, successfully extracted these using the third party ZipMe library. Can anyone let me know, how to get the signature block from the .DSA/.RSA file to authenticate the jar? I have the certificate that was used to sign the jar as well. This is easily done in Java using the getCertificates() method available in java.util.jar.JarFile. Is there any 3rd party API available that emulates the JarFile for BlackBerry®? Any help in this regard will be deeply appreciated. Thanks & Regards Basilio John Vincent D'souza

• Returning more than one result

  - by Hairr

  I'm using the following code: def recentchanges(bot=False,rclimit=20): """ @description: Gets the last 20 pages edited on the recent changes and who the user who edited it """ recent_changes_data = { 'action':'query', 'list':'recentchanges', 'rcprop':'user|title', 'rclimit':rclimit, 'format':'json' } if bot is False: recent_changes_data['rcshow'] = '!bot' else: pass data = urllib.urlencode(recent_changes_data) response = opener.open('http://runescape.wikia.com/api.php',data) content = json.load(response) pages = tuple(content['query']['recentchanges']) for title in pages: return title['title'] When I do recentchanges() I only get one result. If I print it though, all the pages are printed. Am I just misunderstanding or is this something relating to python? Also, opener is: cj = CookieJar() opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))

• Long polling with NSURLConnection

  - by pix0r

  I'm working on an iPhone application which will use long-polling to send event notifications from the server to the client over HTTP. After opening a connection on the server I'm sending small bits of JSON that represent events, as they occur. I am finding that -[NSURLConnectionDelegate connection:didReceiveData] is not being called until after I close the connection, regardless of the cache settings I use when creating the NSURLRequest. I've verified that the server end is working as expected - the first JSON event will be sent immediately, and subsequent events will be sent over the wire as they occur. Is there a way to use NSURLConnection to receive these events as they occur, or will I need to instead drop down to the CFSocket API? I'm starting to work on integrating CocoaAsyncSocket, but would prefer to continue using NSURLConnection if possible as it fits much better with the rest of my REST/JSON-based web service structure.

• How to Delete a Row with DataTables Plugin?

  - by chobo2

  Hi I am trying to delete a row using the DataTables plugin. First I don't get the example at all. What I have this is a user checks the row they want to delete. I do this then var row = $('#id :checked').parents('tr'); So I get the row of the checked checkbox. Lets assume they only check one box( if multiple where choose it might be different - might need a jquery each loop). I then try to do this var position = GlobalVariable.fnGetPosition(row); GlobalVariable.fnDeleteRow(position); position is always null and So I have no clue how to do this. http://datatables.net/api

• Calculated property with JPA / Hibernate

  - by Francois

  My Java bean has a childCount property. This property is not mapped to a database column. Instead, it should be calculated by the database with a COUNT() function operating on the join of my Java bean and its children. It would be even better if this property could be calculated on demand / "lazily", but this is not mandatory. In the worst case scenario, I can set this bean's property with HQL or the Criteria API, but I would prefer not to. The Hibernate @Formula annotation may help, but I could barely find any documentation. Any help greatly appreciated. Thanks.

• List of private iPhone APIs?

  - by diego nunes

  . . Hi there, everybody. . . I need to do an app to be distributed ad hoc (it doesn't need to go to the store) but I need to get the information about the "data usage" (gprs/3g traffic). It is available on the system, but there is no official API call to get that info. One app made it through Apple testing (it's called "Download Meter"), though, and I emailed the guys to see if they would share the call, but they were not in that mood. . . Is there any list of private APIs or anything like that? Does anyone have any ideas of how could I get that info? Again: the app doesn't need to go to the store, but I need to install it on stock iPhone (ad hoc will do). . Thanks.

• DWR and other possible tools for build java application level Ajax framework

  - by Fazal

  I would assume that this question would have been asked in different ways already, but I could not find one so posting it. Sorry if its a repetition The basic idea which I am trying to explore is to design a common Ajax framework/API for our application. The main requirement is to have a common framework in the product which every module in the application can call whenever it needs to provide Ajax behavior. We basically have a page based application and not everything would be Ajax for sure. Mostly it will be smaller pieces of work which Ajax will handle. We have used GWT and it works great. But we have some constraints because of which certain areas in the application need to build standard jsp and html pages only I know little bit about dwr and it looks very promising (as even answered by some people). I wanted to know what are the other possible frameworks like dwr which I can evaluate too, before making the decision

• Authlogic: Create records on other users' behalf

  - by Friðrik

  Hi Using Authlogic, what is the best way to create a record in rails on other users' behalf? Description: I have a c++ server which handles Tcp connections from many c++ clients, and I want the c++ server to create a new record in the rails database using its REST api. However, the c++ server needs to be authenticated before creating that record. What I want is to attach the original user ID (from the c++ client) to the record (but not the servers) so I know from which user the record came from. One way is for the c++ client to send its persistence token over to the c++ server which sends that token as a parameter to the create action, does that make sense? or are there maybe some better ways to do this? I have a rails app which uses authlogic for authentication. I also have another c++ client which is logs in and provides I have a c++ server which uses

• How might I escape Unicode characters in a JSON string using JavaScript?

  - by user293006

  JSON String: { "id":31896, "name":"Zickey attitude - McKinley, La Rosi\u00e8re, 21 ao\u00fbt 2006", ... } this causes an unterminated string in JavaScript. My attempt at a solution is: data.replace(/(\S)\1(\1)+/g, ''); or data.replace(/\\u([0-9A-Z])/, ''); any ideas/solution? Example: http://api.jamendo.com/get2/id+name+url+stream+album_name+album_url+album_id+artist_id+artist_name/track/jsonpretty/track_album+album_artist/?n=13&order=ratingmonth_desc&tag_idstr=jazz last node is the problem, fyi.

• How does this If conditional work in Python?

  - by Sergio Boombastic

  from google.appengine.api import users from google.appengine.ext import webapp from google.appengine.ext.webapp.util import run_wsgi_app class MainPage(webapp.RequestHandler): def get(self): user = users.get_current_user() if user: self.response.headers['Content-Type'] = 'text/plain' self.response.out.write('Hello, ' + user.nickname()) else: self.redirect(users.create_login_url(self.request.uri)) application = webapp.WSGIApplication( [('/', MainPage)], debug=True) def main(): run_wsgi_app(application) if __name__ == "__main__": main() I don't understand how this line works: if user: self.response.headers['Content-Type'] = 'text/plain' self.response.out.write('Hello, ' + user.nickname()) else: self.redirect(users.create_login_url(self.request.uri)) I'm guessing the users.get_current_user() return a boolean? Then, if that is the case how can it get a .nickname() method? Thanks for the guidance.

• Should I use Drupal or Kohana-type framework for a web "application"

  - by Andres

  The debate is that I need a PHP Framework/Drupal with the flexibility to add custom features to a potentially large application (web and with an api). However, with a framework, like Kohana, I see myself tackling and re-inventing the wheel with the simple stuff like account management and cms stuff. Account management and quick data collection, like fast form creation, are tedious in Kohana but appear incredible simple in Drupal. On the other hand, based on my limited Drupal experience, I doubt building rapid custom "features" and allowing users to create "groups" and to manage their own roles within those groups is something Drupal can easily accomplish. To simplify, is Drupal capable of true Web Applications; where the application is a service and provides custom results to each user? Can it provide a dashboard-like interface for users to change their settings or preferences? Can it aggregate data from particular users to provide better results/info to others? If so, please point me to some knowledge :-)

  - by Chez

  In google analytics, what is 'ga:accountName' for ? it might seem like a straightforward question but I can't find anywhere some documentation which tells me what ga:accountName is supposed to return. if I run the google's code from the java example: private static void getAccountFeed(AnalyticsService analyticsService) throws IOException, MalformedURLException, ServiceException { // Construct query from a string. URL queryUrl = new URL( "https://www.google.com/analytics/feeds/accounts/default?max-results=10"); // Make request to the API. AccountFeed accountFeed = analyticsService.getFeed(queryUrl, AccountFeed.class); // Output the data to the screen. System.out.println("-------- Account Feed Results --------"); for (AccountEntry entry : accountFeed.getEntries()) { System.out.println( "\nAccount Name = " + entry.getProperty("ga:accountName") + "\nProfile Name = " + entry.getTitle().getPlainText() + "\nProfile Id = " + entry.getProperty("ga:profileId") + "\nTable Id = " + entry.getTableId().getValue()); } } it does return my website. can anybody help ? thanks

• Disconnect a bluetooth socket in Android

  - by rejoperejo

  Hi, I'm developing a program in which, from an Android Phone, I have to connect as a client to a Bluetooth medical sensor. I'm using the official Bluetooth API and no problem during connection (SPP profile), but when I end the socket, the sensor is still connected to my phone (although I have close the connection). Are there any way to make a Bluetooth disconnection? I think there is an intent called ACTION_ACL_CONNECTED, which does that. Can anyone explain me how to use this? Thanks in advance.

• How to determine what invokes User Access Control restrictions?

  - by MX4399

  In a Delphi app intended to build an internet software update service for my software, the Windows 7 UAC system requests authorization from the user to run the exe.The following possible contentious/risk areas exist in the code: A named pipe server is created for communications TCP is used for FTP and HTTP SHGetSpecialFolderPath api call is used Before these items where added UAC did not activate, removing each in turn including all unit reference and then ending with the bare bones exe still causes the UAC event - so its not possible say what is causing it. On top of this Delphi 2007 now requires being launced as an administrator to launcg a debugging process for the app. Question 1 : How can I see what is causing this besides starting from scratch in a new exe - IOW is there a log somewhere I can check Question 2 : Will using a signed exe using authenticode still cause the UAC alert to show

• How to manage end user documentation for a project under continuous integration?

  - by mcdon

  I have a project under continuous integration and would like to add end user documentation to the project. The end user documentation is a user manual, not API documentation. In our environment we use windows, c#, msbuild, cruisecontrol.net and subversion. We are currently using DocToHelp to create our help file, which is based on an msword document. I'm looking for some guidance on how to manage the end user documentation. What documentation tools should I use? Should any of the documentation tools be part of the build script? Should the output files from the documentation tool be stored in subversion? What type of help files would be best to use?

• Performing complicated XPath queries in Scala

  - by Ken Bloom

  What's the simplest API to use in scala to perform the following XPath queries on a document? //s:Annotation[@type='attitude']/s:Content/s:Parameter[@role='type' and not(text())] //s:Annotation[s:Content/s:Parameter[@role='id' and not(text())]]/@type The only documentation I can find on Scala's XML libraries has no information on performing complicated real XPath queries. I used to like JDOM for this purpose (in Java), but since JDOM doesn't support generics, it will be painful to work with in Scala. (Other XML libraries for Java have tended to be even more painful in Java, but I admit I don't know the landscape real well.)

• In what language was MSDOS originally written?

  - by nebukadnezzar

  In what language was MSDOS originally written in? The Wikipedia Article implies either C, QBasic or Pascal, but: C was invented to write UNIX, so I don't believe it was used to write MSDOS Pascal seems popular to teach programming, but not really popular to write Operating systems in QBasic didn't seem to be very popular for Operating Systems at the time MSDOS was developed (or was *BASIC ever very popular to write Operating Systems in it?) Except these three languages there is also Assembly, but I assume that Microsoft already switched from Assembly to a "higher" level language? Since C was originally invented for UNIX, I still wouldn't think Microsoft is using C... although the Microsoft API is written in C (I find this kind-of oxymoronic, actually). Can anyone enlighten me on this topic?

• How to learn to program C the right way

  - by sfactor

  i have been programming in C/C++ for my academic courses a lot and was under the impression i had a pretty good grasp of it. but lately i had to work in a bluetooth application that had a server and client implementation in a Linux box and an embedded system. i learned bluez bluetooth API, socket/network programming and coded it. however i ran into a lot of problems with memory leaks and segmentation faults and other memory related errors along the way.as the code grew more complex i all but lost control of the pointers and threads and sockets. this got me wondering that i had a lot to learn that they didn't say in the basic C/C++ books. so i wanted to ask for the resources that are available that'll help be code better in a professional way in C/C++ .especially for the Linux/Mac environment (gcc compiler).

• Programatically get own Phone Number in iPhone OS 4.0

  - by sandy

  I am developing an iPhone application for jail broken phones and in this application I would like to fetch user's phone number. I have gone through the entire stackoverflow.com and found some relevant answers but all of them are obsolete and doesn't work with iOS 4.0 anymore. The most famous solution for this problem is NSString *num = [[NSUserDefaults standardUserDefaults] stringForKey:@"SBFormattedPhoneNumber"]; but as I mentioned this solution no more works with iOS 4.0 As my application is intended towards the jail broken phones and not intended the Apple app store so I am not worried about my app rejection, hence any private API will also work for me. Also please let me know if we can fetch IMSI number from SIM using any private APIs of iPhone

• How to use this Color's constructor? Java

  - by MaxMackie

  According to Oracle's site, the class Color has a constructor that accepts a single int value which represents an RGB value. http://download.oracle.com/javase/1.4.2/docs/api/java/awt/Color.html#Color(int) An RGB color is actually three different numbers ranging from 0-255. So combining them together to make one int would look like this: White 255,255,255 White 255255255 Right? So I pass this to the constructor and get a vibrant teal color. What am I doing wrong? What haven't I understood?

• Custom Message Box: Windows' "Move Cursor to Default Button" Feature

  - by Andreas Rejbrand

  In Microsoft Windows, there is a (highly useful) feature that automatically moves the cursor to the default button of a modal dialog box (activated in Win+R, "control mouse"). Now I have created a custom dialog box in Delphi (basically a TForm), see below. But, quite naturally, the cursor does not automatically move to the default button ("Yes" in this case), even though the feature is turned on in "control mouse". How to implement this feature using Windows API? I guess it would be sufficient to obtain the settings as a boolean (true if feature activated, false if not), and then simply move the cursor programmatically using SetCursorPos if true. But how to obtain this setting?

• Using thrift to mix development languages

  - by christopher-mccann

  I am currently developing an application which will require multiple different development languages. I want to use PHP as the final piece of the puzzle - the physical web page construction. This PHP web app will need to contact multiple web services which could be coded in anything from Java to Erlang to Python. Each of these web services will be implemented with an API. My plan is to use Thrift to allow this mix to work. Is this the correct approach or am I mixing up what the whole point of Thrift is?
