  • Enabling Service Broker in SQL Server 2008

    - by Truegilly
    Hello, I am integrating SqlCacheDependency to use in my LinqToSQL datacontext. I am using an extension class for Linq querys found here - http://code.msdn.microsoft.com/linqtosqlcache I have wired up the code and when I open the page I get this exception - "The SQL Server Service Broker for the current database is not enabled, and as a result query notifications are not supported. Please enable the Service Broker for this database if you wish to use notifications." its coming from this event in the global.asax protected void Application_Start() { RegisterRoutes(RouteTable.Routes); //In Application Start Event System.Data.SqlClient.SqlDependency.Start(new dataContextDataContext().Connection.ConnectionString); } my question is... how do i enable Service Broker in my SQL server 2008 database? I have tried to run this query.. ALTER DATABASE tablename SET ENABLE_BROKER but it never ends and runs for ever, I have to manually stop it. once I have this set in SQL server 2008, will it filter down to my DataContext, or do I need to configure something there too ? thanks for any help Truegilly

  • Auth problem on Facebook using Ruby/sinatra/frankie/facebooker

    - by user84584
    Hello guys, I'm using sinatra/frankie/facebooker to prototype something simple to test the facebook api, i'm using mmangino-facebooker the more recent version from github and I cloned the most recent version of frankie. I'm using sinatra 0.9.6. My main code is as simple as possible: before do ensure_application_is_installed_by_facebook_user @user = session[:facebook_session].user @photos = session[:facebook_session].get_photos(nil,@user.uid,nil) end get "/" do erb :index end get "/:uid/:image" do |uid,image| @photo_selected = session[:facebook_session].get_photos([image.to_i],nil,nil) erb :selected end The index page just renders a link to the other one (identified by regex "/:uid/:image") however I always get an error when it's trying to render the one identified by regex "/:uid/:image" Facebooker::Session::MissingOrInvalidParameter: Invalid parameter /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/parser.rb:610:in `process' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/parser.rb:30:in `parse' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/service.rb:67:in `post' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/session.rb:600:in `post_without_logging' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/session.rb:611:in `post' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/logging.rb:20:in `log_fb_api' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/benchmark.rb:308:in `realtime' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/logging.rb:20:in `log_fb_api' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/session.rb:610:in `post' /Library/Ruby/Gems/1.8/gems/mmangino-facebooker-1.0.50/lib/facebooker/session.rb:198:in `secure!' ./config/frankie/lib/frankie.rb:66:in `secure_with_token!' ./config/frankie/lib/frankie.rb:44:in `set_facebook_session' ./config/frankie/lib/frankie.rb:164:in `ensure_authenticated_to_facebook' ./config/frankie/lib/frankie.rb:169:in `ensure_application_is_installed_by_facebook_user' I've no idea why, it seems to be related with the auth token I guess..

Cheers and tks, Ze Maria

  • Using ContentProviderOperation to update and insert contacts

    - by Bogus
    Hello, I faced the problem updating/insertng contacts on Android 2.0+. There is no problem to insert a new contact when phone book is empty but when I did it 2nd time some fileds like TEL, EMAIL are doubled and tripped etc. but N, FN, ORG are ok (one copy). After getting and advice of other member this forum I updated a contact first and then ContentProviderResult[] returned uri's with null then I do an insert action and it went ok but after that I made an update and all contacts are aggregated into one - i got 1 contact insted 3 which existed in phone book. This one was damaged, the contact fields are randomly built. I set Google account. Code: ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>(); ops.add(ContentProviderOperation.newUpdate(ContactsContract.RawContacts.CONTENT_URI) .withValue(RawContacts.AGGREGATION_MODE, RawContacts.AGGREGATION_MODE_DISABLED) .withValue(ContactsContract.RawContacts.ACCOUNT_TYPE, accountType) .withValue(ContactsContract.RawContacts.ACCOUNT_NAME, accountName) .build()); // add name ContentProviderOperation.Builder builder = ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI); builder.withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0); builder.withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE); builder.withValue(ContactsContract.CommonDataKinds.StructuredName.PHONETIC_FAMILY_NAME, name); // phones ContentProviderOperation.Builder builder = ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI); builder.withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0); builder.withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE); builder.withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, phoneValue); builder.withValue(ContactsContract.CommonDataKinds.Phone.TYPE, phoneType); builder.withValue(ContactsContract.CommonDataKinds.Phone.LABEL, phoneLabel); ops.add(builder.build()); // emails ... // orgs ... try { ContentProviderResult[] result = mContentResolver.applyBatch(ContactsContract.AUTHORITY, ops); } } catch (Exception e) { Log.e(LOG_TAG, "Exception while contact updating: " + e.getMessage()); } What is wrong in this solution ? How does work aggregation engine ? I will be glad for help. Bogus

  • stoping doGet/dopost in java servlets ?

    - by bosso
    Hello everyone, I've been playing with Java Servlets and Ajax a bit, and I've got a situation on which I would really appreciate advice. Let's say I have HTML page with a start and stop buttons, and as a result of clicking start button, overridden doGet (or doPost) method on a servlet is invoked which computes something that takes a long time to complete. (e.g. a giant loop, or even Infinite loop, doesn't matter, I'm interested in concepts here). So, I'm asking you: 1.What would be my options to kill / shut down / halt / exit doGet method whan I hit stop button on a web page? Do I use threading here, or there is simpler way? I take it that using System exit is not a very good idea, right? ;) 2.So, let's say I implement code for stopping doGet method. What would happen If I hit start on one browser(e.g.IE), and while this long computation takes place open new tab or other browser(e.g.Firefox) and open same url and hit stop? Would that stop my original computation? Is there any easy way to avoid this? I know that questions are a bit off, as I'm just starting with server-side of things. :) Any suggestions would be greatly appreciated!

  • PHP: Detect encoding and make everything UTF-8

    - by marco92w
    Hello! I'm reading out lots of texts from various RSS feeds and inserting them into my database. Of course, there are several different character encodings used in the feeds, e.g. UTF-8 and ISO-8859-1. Unfortunately, there are sometimes problems with the encodings of the texts. Example: 1) The "ß" in "Fußball" should look like this in my database: "Ÿ". If it is a "Ÿ", it is displayed correctly. 2) Sometimes, the "ß" in "Fußball" looks like this in my database: "ß". Then it is displayed wrongly, of course. 3) In other cases, the "ß" is saved as a "ß" - so without any change. Then it is also displayed wrongly. What can I do to avoid the cases 2 and 3? How can I make everything the same encoding, preferably UTF-8? When must I use utf8_encode(), when must I use utf8_decode() (it's clear what the effect is but when must I use the functions?) and when must I do nothing with the input? Can you help me and tell me how to make everything the same encoding? Perhaps with the function mb-detect-encoding()? Can I write a function for this? So my problems are: 1) How to find out what encoding the text uses 2) How to convert it to UTF-8 - whatever the old encoding is Thanks in advance! EDIT: Would a function like this work? function correct_encoding($text) { $current_encoding = mb_detect_encoding($text, 'auto'); $text = iconv($current_encoding, 'UTF-8', $text); return $text; } I've tested it but it doesn't work. What's wrong with it?

  • Extjs to call a RESTful webservice

    - by VSC
    Hello, I am trying to make a RESTful webservice call using Extjs. Below is the code i am using: Ext.Ajax.request({ url: incomingURL , method: 'POST', params: {param1:p1, param2:p2}, success: function(responseObject){ var obj = Ext.decode(responseObject.responseText); alert(obj); }, failure: function(responseObject){ var obj = Ext.decode(responseObject.responseText); alert(obj); } }); but it does not work, the request is sent using OPTIONS method instead of POST. I also tried to do the same thing using below code but result is the same: var conn = new Ext.data.Connection(); conn.request({ url: incomingURL, method: 'POST', params: {param1:p1, param2:p2}, success: function(responseObject) { Ext.Msg.alert('Status', 'success'); }, failure: function(responseObject) { Ext.Msg.alert('Status', 'Failure'); } }); But when i tried to do the same thing using basic ajax call ( using the browser objects directly i.e. XMLHttpRequest() or ActiveXObject("Microsoft.XMLHTTP")) it works fine and i get the response as expected. Can anyone please help me, as i am not able to understand what i am doing wrong with extjs ajax call?

  • pulling an UIImage from a UITextView or UILabel gives white image

    - by user293139
    Hello all, I need to grab an UIImage from a UITextView or UILabel. I've got a method that will pull an image successfully from other types of views ( [UIViewController view], MKMapView, UIButtons) but I am just getting a white rect for my UITextView. I've been banging my head against the wall for a while and suspect something really, really basic. many thanks! @interface TaskAccomplishmentViewController : UIViewController { MKMapView *mapView; UILabel *timeLeftText; UITextView *challengeText; UIButton *successButton; -(void) setChallangeImageToImageFromChallenge { // works // [currChallenge setChallengeImage:[UIImageUtils grabImageFromView:mapView]]; // [currChallenge setChallengeImage:[UIImageUtils grabImageFromView:[self view]]]; // [currChallenge setChallengeImage:[UIImageUtils grabImageFromView:successButton]]; //doesn't work // [currChallenge setChallengeImage:[UIImageUtils grabImageFromView:timeLeftText]]; [currChallenge setChallengeImage:[UIImageUtils grabImageFromView:challengeText]]; } and the grabImage from a UIView code +(UIImage *)grabImageFromView: (UIView *) viewToGrab { UIGraphicsBeginImageContext(viewToGrab.bounds.size); [[viewToGrab layer] renderInContext:UIGraphicsGetCurrentContext()]; UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return viewImage; }

  • Sparse parameter selection using Genetic Algorithm

    - by bgbg
    Hello, I'm facing a parameter selection problem, which I would like to solve using Genetic Algorithm (GA). I'm supposed to select not more than 4 parameters out of 3000 possible ones. Using the binary chromosome representation seems like a natural choice. The evaluation function punishes too many "selected" attributes and if the number of attributes is acceptable, it then evaluates the selection. The problem is that in these sparse conditions the GA can hardly improve the population. Neither the average fitness cost, nor the fitness of the "worst" individual improves over the generations. All I see is slight (even tiny) improvement in the score of the best individual, which, I suppose, is a result of random sampling. Encoding the problem using indices of the parameters doesn't work either. This is most probably, due to the fact that the chromosomes are directional, while the selection problem isn't (i.e. chromosomes [1, 2, 3, 4]; [4, 3, 2, 1]; [3, 2, 4, 1] etc. are identical) What problem representation would you suggest? P.S If this matters, I use PyEvolve.

  • Async.Parallel or Array.Parallel.Map ?

    - by gurteen2
    Hello- I'm trying to implement a pattern I read from Don Syme's blog (http://blogs.msdn.com/dsyme/archive/2010/01/09/async-and-parallel-design-patterns-in-f-parallelizing-cpu-and-i-o-computations.aspx) which suggests that there are opportunities for massive performance improvements from leveraging asynchronous I/O. I am currently trying to take a piece of code that "works" one way, using Array.Parallel.Map, and see if I can somehow achieve the same result using Async.Parallel, but I really don't understand Async.Parallel, and cannot get anything to work. I have a piece of code (simplified below to illustrate the point) that successfully retrieves an array of data for one cusip. (A price series, for example) let getStockData cusip = let D = DataProvider() let arr = D.GetPriceSeries(cusip) return arr let data = Array.Parallel.map (fun x -> getStockData x) stockCusips So this approach contructs an array of arrays, by making a connection over the internet to my data vendor for each stock (which could be as many as 3000) and returns me an array of arrays (1 per stock, with a price series for each one). I admittedly don't understand what goes on underneath Array.Parallel.map, but am wondering if this is a scenario where there are resources wasted under the hood, and it actually could be faster using asynchronous I/O? So to test this out, I have attempted to make this function using asyncs, and I think that the function below follows the pattern in Don Syme's article using the URLs, but it won't compile with "let!". let getStockDataAsync cusip = async { let D = DataProvider() let! arr = D.GetData(cusip) return arr } The error I get is: This expression was expected to have type Async<'a but here has type obj It compiles fine with "let" instead of "let!", but I had thought the whole point was that you need the exclamation point in order for the command to run without blocking a thread. So the first question really is, what's wrong with my syntax above, in getStockDataAsync, and then at a higher level, can anyone offer some additional insight about asychronous I/O and whether the scenario I have presented would benefit from it, making it potentially much, much faster than Array.Parallel.map? Thanks so much.

  • Tail-recursive merge sort in OCaml

    - by CFP
    Hello world! I’m trying to implement a tail-recursive list-sorting function in OCaml, and I’ve come up with the following code: let tailrec_merge_sort l = let split l = let rec _split source left right = match source with | [] -> (left, right) | head :: tail -> _split tail right (head :: left) in _split l [] [] in let merge l1 l2 = let rec _merge l1 l2 result = match l1, l2 with | [], [] -> result | [], h :: t | h :: t, [] -> _merge [] t (h :: result) | h1 :: t1, h2 :: t2 -> if h1 < h2 then _merge t1 l2 (h1 :: result) else _merge l1 t2 (h2 :: result) in List.rev (_merge l1 l2 []) in let rec sort = function | [] -> [] | [a] -> [a] | list -> let left, right = split list in merge (sort left) (sort right) in sort l ;; Yet it seems that it is not actually tail-recursive, since I encounter a "Stack overflow during evaluation (looping recursion?)" error. Could you please help me spot the non tail-recursive call in this code? I've searched quite a lot, without finding it. Cout it be the let binding in the sort function? Thanks a lot, CFP.

  • TRY CATCH with Linked Server in SQL Server 2005 Not Working

    - by Robert Stanley
    Hello, I am trying to catch sql error raised when I execute a stored procedure on a linked server. Both Servers are running SQL Server 2005. To prove the issue I have created a stored procedure on the linked server called Raise error that executes the following code: RAISERROR('An error', 16, 1); If I execute the stored procedure directly on the linked server using the following code I get a result set with 'An error', '16' as expected (ie the code enters the catch block): BEGIN TRY EXEC [dbo].[RaiseError]; END TRY BEGIN CATCH DECLARE @ErrMsg nvarchar(4000), @ErrSeverity int; SELECT @ErrMsg = ERROR_MESSAGE(), @ErrSeverity = ERROR_SEVERITY(); SELECT @ErrMsg, @ErrSeverity; END CATCH If I run the following code on my local server to execute the stored procedure on the linked server then SSMS gives me the message 'Query completed with errors', .Msg 50000, Level 16, State 1, Procedure RaiseError, Line 13 An error' BEGIN TRY EXEC [Server].[Catalog].[dbo].RaiseError END TRY BEGIN CATCH DECLARE @SPErrMsg nvarchar(4000), @SPErrSeverity int; SELECT @SPErrMsg = ERROR_MESSAGE(), @SPErrSeverity = ERROR_SEVERITY(); SELECT @SPErrMsg, @SPErrSeverity; END CATCH My Question is can I catch the error generated when the Linked server stored procedure executes? Thanks in advance!

  • Grails - Development advice - Where do I find Plugin APIs / Troubleshoot errors / Make life easy for

    - by gav
    Hello fellow Grails Developers! I was wondering if you could help me with what must be a very common issue. I have come from a world of Java and eclipse where JavaDocs and APIs are at your fingertips. Grails has some great features and plugins but I find their inner workings completely undescoverable and that makes me sad. Take for example the excellent authentication plugin, I set this up using the brief but accurate doc. Now I'm in eclipse with STS and I'm staring at a method; applicationContext.authenticationService.filterRequest( request, response, "${request.contextPath}/authentication/index" ) Which is throwing an exception; 2010-05-01 01:17:07,292 [http-8080-1] ERROR [/grailsapp].[default] - Servlet.service() for servlet default threw exception java.lang.IllegalStateException at org.apache.catalina.connector.ResponseFacade.sendError(ResponseFacade.java:407) at javax.servlet.http.HttpServletResponseWrapper.sendError(HttpServletResponseWrapper.java:118) at org.codehaus.groovy.grails.web.sitemesh.GrailsPageResponseWrapper.sendError(GrailsPageResponseWrapper.java:91) And I have no idea where to start. I would love to have eclipse link to the source but there must be other manageable alternatives too as I know some people use TextMate or vim for development, they can't all have discovered the APIs for the plugins through trial and error!?! Is there any way of making the core Grails API more accessible / searchable? Autocomplete also doesn't seem to work for me in eclipse so if anyone has this working that would be ideal (It's an extension of the same question really). What's your approach? (Please don't say intelliJ, I can't afford it) I'm sure it's obvious and I'm just missing it, please put me out of my misery! Thanks in advance, Gav

  • Jquery cookie plugin - conditional content determined by cookie being set

    - by Dave
    Hello I have a sign up form that is displayed to all new site visitors. If a user fills out the form, the next time they visit the site, I would like to display a "welcome back" message where the form would usually sit. I am trying to do this via the jquery cookie plugin (http://plugins.jquery.com/project/Cookie). My form would look like this: <div id="sign_up_form_wrapper"><form id="sign_up" action="" method="POST" name="form"> <input type="checkbox" name="checkbox" id="checkbox" value="1">&nbsp; I accept the terms and conditions</a> <br /><br /><input type="submit" value="ENTER"> </form></div> And I am setting my cookie here: <script type="text/javascript" language="javascript"> $().ready(function() { $('#sign_upm').submit(function(e) { e.preventDefault(); if ($('#sign_up input[name=checkbox]').is(':checked')) { $.cookie('agreed_to_terms', '1', { path: '/', expires: 999999 }); } }); }); </script> That will set the cookie when a user has checked the box, but now I need to do somehting like this: if the cookie has been set, do this: <div id="sign_up_form_wrapper"> <p>Welcome back, John</p> </div> otherwise do this: <div id="sign_up_form_wrapper"> <!-- full form code here --> </div> Any ideas or pointers would be very appreciated, thanks.

  • Hibernate JPA 2.0 CriteriaQuery, subset listing and counting at once

    - by Jeroen
    Hello, I recently started using the new Hibernate (EntityManager) 3.5.1 with JPA 2.0, and I was wondering if it was possible to both retrieve a (sub-set) of entities and their count from a single CriteriaQuery instance. My current implementation looks as follows: class HibernateResult<T> extends AbstractResult<T> { /** * Construct a new {@link HibernateResult}. * @param criteriaQuery the criteria query * @param selector the selector that determines the entities to return */ HibernateResult(CriteriaQuery<T> criteriaQuery, Selector selector, EntityManager entityManager) { CriteriaBuilder builder = entityManager.getCriteriaBuilder(); // Count the entities CriteriaQuery<Long> countQuery = builder.createQuery(Long.class); Root<T> path = criteriaQuery.from(criteriaQuery.getResultType()); countQuery.select(builder.count(path)); final int count = entityManager.createQuery(countQuery).getSingleResult().intValue(); this.setCount(count); // List the entities according to selector TypedQuery<T> entityQuery = entityManager.createQuery(criteriaQuery); entityQuery.setFirstResult(selector.getFirstResult()); entityQuery.setMaxResults(selector.getMaxRecords()); List<T> entities = entityQuery.getResultList(); this.setEntities(entities); } } The thing is that I want to count all entities that match my criteria query, but the count method from CriteriaBuilder only seems to take Expression as argument. Is there any quick way of converting my criteria query to an expression?

    - by Kenneth B
    Hello guys and gals... I have a LI with some information, including some links. I would like jQuery to make the LI clickable, but also remain the links in the LI. The Clickable part works. I just need the links within to work as well. NOTE: They work if you right click and choose "Open in new tab". HTML <ul id="onskeliste"> <li url="http://www.dr.dk">Some info with links <a href="http://www.imerco.dk" target="_blank">Imerco</a></a> </ul> jQuery $(document).ready(function() { $("#onskeliste li").click( function() { window.location = $(this).attr("url"); return false; }); })(jQuery); I've found a simular question here, but it doesn't seem to solve my problem. http://stackoverflow.com/questions/180211/jquery-div-click-with-anchors Can you help me?? :-) Thank you in advance...

  • Using sqlite from vala without dependence on glib

    - by celil
    I need to use the Sqlite vapi without any depedence on GLib. SQlite is non-gobject library, so it should be possible to do that. However, when I try to compile the following file with the --profile posix option, using Sqlite; void main() { stdout.printf("Hello, World!"); } I get am error messages: sqlite3.vapi:357.56-357.59: error: The symbol `GLib' could not be found public int bind_blob (int index, void* value, int n, GLib.DestroyNotify destroy_notify); ^^^^ sqlite3.vapi:362.68-362.71: error: The symbol `GLib' could not be found public int bind_text (int index, owned string value, int n = -1, GLib.DestroyNotify destroy_notify = GLib.g_free); ^^^^ sqlite3.vapi:411.42-411.45: error: The symbol `GLib' could not be found public void result_blob (uint8[] data, GLib.DestroyNotify? destroy_notify = GLib.g_free); ^^^^ sqlite3.vapi:420.59-420.62: error: The symbol `GLib' could not be found public void result_text (string value, int length = -1, GLib.DestroyNotify? destroy_notify = GLib.g_free); ^^^^ Compilation failed: 4 error(s), 0 warning(s) It seems that several of the functions defined in the sqlite vapi make references to the GLib.g_free and GLib.DestroyNotify symbols. Are there any posix alternatives to those?

  • CreateProcess doesn't pass command line arguments

    - by mnh
    Hello I have the following code but it isn't working as expected, can't figure out what the problem is. Basically, I'm executing a process (a .NET process) and passing it command line arguments, it is executed successfully by CreateProcess() but CreateProcess() isn't passing the command line arguments What am I doing wrong here?? int main(int argc, char* argv[]) { PROCESS_INFORMATION ProcessInfo; //This is what we get as an [out] parameter STARTUPINFO StartupInfo; //This is an [in] parameter ZeroMemory(&StartupInfo, sizeof(StartupInfo)); StartupInfo.cb = sizeof StartupInfo ; //Only compulsory field LPTSTR cmdArgs = "[email protected]"; if(CreateProcess("D:\\email\\smtp.exe", cmdArgs, NULL,NULL,FALSE,0,NULL, NULL,&StartupInfo,&ProcessInfo)) { WaitForSingleObject(ProcessInfo.hProcess,INFINITE); CloseHandle(ProcessInfo.hThread); CloseHandle(ProcessInfo.hProcess); printf("Yohoo!"); } else { printf("The process could not be started..."); } return 0; } EDIT: Hey one more thing, if I pass my cmdArgs like this: // a space as the first character LPTSTR cmdArgs = " [email protected]"; Then I get the error, then CreateProcess returns TRUE but my target process isn't executed.

  • Conversion from Iphone Core Surface RGB Frame into ffmepg AVFarme

    - by Sridhar
    Hello, I am trying to convert Core Surface RGB frame buffer(Iphone) to ffmpeg Avfarme to encode into a movie file. But I am not getting the correct video output (video showing colors dazzling not the correct picture) I guess there is something wrong with converting from core surface frame buffer into AVFrame. Here is my code : Surface *surface = [[Surface alloc]initWithCoreSurfaceBuffer:coreSurfaceBuffer]; [surface lock]; unsigned int height = surface.height; unsigned int width = surface.width; unsigned int alignmentedBytesPerRow = (width * 4); if (!readblePixels) { readblePixels = CGBitmapAllocateData(alignmentedBytesPerRow * height); NSLog(@"alloced readablepixels"); } unsigned int bytesPerRow = surface.bytesPerRow; void *pixels = surface.baseAddress; for (unsigned int j = 0; j < height; j++) { memcpy(readblePixels + alignmentedBytesPerRow * j, pixels + bytesPerRow * j, bytesPerRow); } pFrameRGB->data[0] = readblePixels; // I guess here is what I am doing wrong. pFrameRGB->data[1] = NULL; pFrameRGB->data[2] = NULL; pFrameRGB->data[3] = NULL; pFrameRGB->linesize[0] = pCodecCtx->width; pFrameRGB->linesize[1] = 0; pFrameRGB->linesize[2] = 0; pFrameRGB->linesize[3] = 0; sws_scale (img_convert_ctx, pFrameRGB->data, pFrameRGB->linesize, 0, pCodecCtx->height, pFrameYUV->data, pFrameYUV->linesize); Please help me out. Thanks, Raghu

  • Roadmap to Android development

    - by Matthew
    Hello, I've done a little research, and am interested in developing for Android. I've never programmed before, and have no idea how to go from zero experience to developing for a mobile device. My interest is in eventually making some sort of 2d game. Is there a lesson plan for starting from the ground up? I would think one would need to learn the Java language to start. Looking at the Sun website, it's a bit daunting. Is there a book, specifically, that would wrap up this knowledge in a bit of a directed lesson plan? I'm not sure if opengl-es is what would be required for 2d games. I've done a little research on this, and it's even far more daunting than Java itself. I can't even begin to figure out where to start with even just opengl, sans -es. My best guess would be that I need further knowledge in Java to continue with this, but even still, is it possible to learn concurrently with Java?

  • Detect Autocomplete

    - by Bryan Marble
    Hello, I have some forms that have inlined labels. I have some javascript (jQuery) that detects when focus has changed or when a user is entering text that changes the class so that the inlined label disappears and isn't blocking the user's view of their entered text. The problem I'm having occurs when the browser autocompletes the form. None of the conditions below are triggered so I can't clear out the inlined label. How can I detect the fact that text has been entered via autocomplete so that I can clear the labels? The js I'm using (from http://www.zurb.com/playground/inline-form-labels): $( document ).ready( function() { $( "label.inlined + .input-text" ).each( function( type ) { $( this ).focus( function() { $( this ).prev( "label.inlined" ).addClass( "focus" ); } ); $( this ).keypress( function() { $( this ).prev( "label.inlined" ).addClass( "has-text" ) .removeClass( "focus" ); } ); $( this ).blur( function() { if( $( this ).val() == "" ) { $( this ).prev( "label.inlined" ).removeClass( "has-text" ) .removeClass( "focus" ); } } ); } ); } ); Thanks! Bryan

  • Rails Counter Cache and its implementation

    - by Ishu
    Hello All, I am trying to get hold of rails counter cache feature but not able to grasp it completely. Let's say that We have 3 models A B C A belongs to B or C depending upon a field key_type and key_id. key_type tells whether A belongs to B or C so if key_type="B" then the record belongs to B otherwise it belongs to C. In my model a.rb, I have defined following associations: belongs_to :b, :counter_cache => true, :foreign_key => "key_id" belongs_to :c, :counter_cache => true, :foreign_key => "key_id" and in b and c model files has_many :as , :conditions => {:key_type => "B"} has_many :as , :conditions => {:key_type => "C"} Both B and C Models have a column as as_count The problem is every time an object of a is created count is increased in the both the models b and c. Any help is appreciated. Initially i thought that this may work: belongs_to :b, :counter_cache => true, :foreign_key => "key_id", :conditions => {:key_type => "B"} belongs_to :c, :counter_cache => true, :foreign_key => "key_id", :conditions => {:key_type => "C"} But this does not help. Thanks

  • PGP Encrypt from C# using GnuPG

    - by Kishore
    Hello All, I'm trying to encrypt a incoming document in C#, and I'm using GnuPG with input redirection. I need to use -se(sign and encrypt) in a single step, which requires entering passphrase. But for some reason, input redirection is not working. Appreciate your help. Control is going to else block. I'm not sure if there is deadlock or child process(gpg.exe) waiting for the input. pgpproc = new Process(); pgpproc.StartInfo.FileName = exeFilePath; pgpproc.StartInfo.RedirectStandardOutput = false; pgpproc.StartInfo.RedirectStandardInput = true; pgpproc.StartInfo.UseShellExecute = false; pgpproc.StartInfo.Arguments = "-a -o C:\PGPStaging\output.pgp -se -r recipientID C:\PGPStaging\input.txt"; pgpproc.StartInfo.CreateNoWindow = true; pgpproc.Start(); StreamWriter myStreamWriter = pgpproc.StandardInput; myStreamWriter.Write("*****"); myStreamWriter.Close(); if (pgpproc.WaitForExit(waittime)) { //success } else { //failure pgpproc.Kill(); pgpproc.WaitForExit(); } `
