  • receive values with XML, AS3

    - by VideoDnd
    My example imports XML and has an object rotating on stage. The rotating object is called enemy corresponds to ENEMY in the XML. How do I set the rotation variable to receive values from XML? REASON It seems more difficult to set up variables using external data. I want to understand it better. rotation.fla //LOAD XML var myXML:XML; var myLoader:URLLoader = new URLLoader(); myLoader.load(new URLRequest("enemy.xml")); myLoader.addEventListener(Event.COMPLETE, processXML); //PARSE XML function processXML(e:Event):void { myXML = new XML(e.target.data); trace(myXML.ROGUE.*); trace(myXML); //TEXT var text:TextField = new TextField(); text.text = myXML.ENEMY.*; addChild(text); } //ROTATION function enterFrameHandler(event:Event):void { //==>CODE I WANT TO CHANGE<== enemy.rotationY += 10; } addEventListener(Event.ENTER_FRAME, enterFrameHandler); enemy.xml ENEMY is set to -100, use what you like <?xml version="1.0" encoding="utf-8"?> <BADGUYS> <ENEMY TITLE="sticky">-100</ENEMY> <ROGUE TITLE="slimy">-1000</ROGUE> </BADGUYS>

  • State Monad, why not a tuple?

    - by thr
    I've just wrapped my head around monads (at least I'd like to think I have) and more specifically the state monad, which some people that are way smarter then me figured out, so I'm probably way of with this question. Anyway, the state monad is usually implemented with a M<'a as something like this (F#): type State<'a, 'state> = State of ('state -> 'a * 'state) Now my question: Is there any reason why you couldn't use a tuple here? Other then the possible ambiguity between MonadA<'a, 'b> and MonadB<'a, 'b> which would both become the equivalent ('a * 'b) tuple. Edit: Added example for clarity type StateMonad() = member m.Return a = (fun s -> a, s) member m.Bind(x, f) = (fun s -> let a, s_ = x s in f a s_) let state = new StateMonad() let getState = (fun s -> s, s) let setState s = (fun _ -> (), s) let execute m s = m s |> fst

  • java RMI connection to server

    - by user85116
    I have a very simple rmi client / server application. I don't use the "rmiregistry" application though, I use this to create the server: server = new RemoteServer(); registry = LocateRegistry.createRegistry(PORT); registry.bind("RemoteServer", server); The client part is: registry = LocateRegistry.getRegistry(IPADDRESS, PORT); remote = (IRemoteServer) registry.lookup("RemoteServer"); Here is the fascinating problem: The application works perfectly when both server and client are running in my (private) local network. As soon as I put the server on a public server, the application hangs for a minute, then gives me the following error: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.ConnectException: Connection refused to host: 192.168.x.y; nested exception is: java.net.ConnectException: Connection timed out: connect at sun.rmi.server.UnicastServerRef.dispatch(Unknown Source) at sun.rmi.transport.Transport$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.Transport.serviceCall(Unknown Source) at sun.rmi.transport.tcp.TCPTransport.handleMessages(Unknown Source) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run0(Unknown Source ... (the rest is truncated) The key I think is that the client (running on my private network) cannot connect to myself (my address is 192.168.x.y where x.y is some other numbers, but the real error message shows my ip address listed there) If I kill the rmi server on the public internet, then I instantly get a "connection refused to host: a.b.c.d") message, so I know that something at the server end is at least working. Any suggestions? EDIT: just to make this a little more clear: 192.168.x.y is the client address, a.b.c.d is the server address. The stacktrace shows the client cannot connect to the client.

  • Binding data to the custom DataGridView

    - by Jatin Chaturvedi
    All, I have a customized DataGridView where I have implemented extra functionality and bounded datasource in the same custom DataGridView (Using C# and .NET). Now, I could able to use it properly by placing it on a panel control. I have added label as button on panel control to display data from datasource on to datagrid and create a binding source. Another Label which act as a button is used to update data from grid to databse. Issue: I pressed show label to display data in a dsatagridview. Modified the grid cell value and immediately pressed update label which is on same panel control. I observed that, the cursor is still in the grid cell when I press Save button. While saving, the cell value is null even though I have entered something in the presentation layer. My expected behaviour is to get the modified value while saving. Special Case: After typing something in the grid cell, if I click on somewhere else like the row below where I entered something, before I click on Save button, it is working fine. (Here, mainly I tried to remove the focus from the currently modified cell) Is there any way to bind sources before I click on save button? Please suggest me. Please feel free to ask me if you need any information. I have also seen same kind of problem on this forum, but unfortunately the author got the answer and didnt post it back. here is that URL: http://social.msdn.microsoft.com/Forums/en/winformsdesigner/thread/54dcc87a-adc2-4965-b306-9aa9e79c2946 Please help me.

  • Foreach is crashing script, but no errors reported.

    - by ILMV
    So I've created this smarty function to get images from my flickr photostream using SimplePie... simple really, or so it should be. The problem I'm having is the foreach will crash the script, this doesn't happen if I put an exit after the closing foreach, of course because of this the rest of my script doesn't execute. The problem also completely subsides if I remove the foreach, I've tested it and it's not the contents of the foreach, but the loop itself. Error reporting is turned on but I don't get any, I also tried messing with the memory_limit, with no luck. Anyone know why this foreach is killing my script? Thanks! function smarty_function_flickr ($params, &$smarty) { require_once('system/library/SimplePie/simplepie.inc'); require_once('system/library/SimplePie/idn/idna_convert.class.php'); $flickr=new flickr(); /** * Set up SimplePie with all default values using shorthand syntax. */ $feed = new SimplePie($params['feed'], 'system/library/SimplePie/cache', '600'); $feed->handle_content_type(); /** * What sizes should we use? * Choices: square, thumb, small, medium, large. */ $thumb = 'square'; $full = 'medium'; $output = array(); $counter=0; // If I comment this foreach out the problem subsides, I know it is not the code within the foreach foreach ($feed->get_items() as $item) { $url = $flickr->image_from_description($item->get_description()); $output[$counter]['title'] = $item->get_title(); $output[$counter]['image'] = $flickr->select_image($url, $full); $output[$counter]['thumb'] = $flickr->select_image($url, $thumb); $counter++; } // Set template variables and template $smarty->assign('flickr',$output); $smarty->display('forms/'.$params['template'].'.tpl'); }

  • How to test the expectation on the eventSpy

    - by Lorraine Bernard
    I am trying to test a backbone.model when saving. Here's my piece of code. As you can see from the comment there is a problem with toHaveBeenCalledOnce method. P.S.: I am using jasmine 1.2.0 and Sinon.JS 1.3.4 describe('when saving', function () { beforeEach(function () { this.server = sinon.fakeServer.create(); this.responseBody = '{"id":3,"title":"Hello","tags":["garden","weekend"]}'; this.server.respondWith( 'POST', Routing.generate(this.apiName), [ 200, {'Content-Type': 'application/json'}, this.responseBody ] ); this.eventSpy = sinon.spy(); }); afterEach(function() { this.server.restore(); }); it('should not save when title is empty', function() { this.model.bind('error', this.eventSpy); this.model.save({'title': ''}); expect(this.eventSpy).toHaveBeenCalledOnce(); // TypeError: Object [object Object] has no method 'toHaveBeenCalledOnce' expect(this.eventSpy).toHaveBeenCalledWith(this.model, 'cannot have an empty title'); }); }); console.log(expect(this.eventSpy));

  • Java: Cipher package (encrypt and decrypt). invalid key error

    - by noinflection
    Hello folks, i am doing a class with static methods to encrypt and decrypt a message using javax.crypto. I have 2 static methods that use ecipher and dcipher in order to do what they are supossed to do i need to initialize some variables (which are static also).

  • jquery control execution of the callback functions

    - by user253530
    Function socialbookmarksTableData(data) is called by another function to generate the content of a table -- data is a JSON object. Inside the function i call 2 other functions that use getJSON and POST (with json as a return object) to get some data. The problem is: though the functions execute correctly i get undefined value for the 2 variables (bookmarkingSites, bookmarkCategories). Help with a solution please. function socialbookmarksGetBookmarkCategories(bookmarkID) { var toReturn = ''; $.post("php/socialbookmark-get-bookmark-categories.php",{ bookmarkID: bookmarkID },function(data){ $.each(data,function(i,categID){ toReturn += '<option value ="' + data[i].categID + '">' + data[i].categName + '</option>'; }) return toReturn; },"JSON"); } function socialbookmarksGetBookmarkSites() { var bookmarkingSites = ''; $.getJSON("php/socialbookmark-get-bookmarking-sites.php",function(bookmarks){ for(var i = 0; i < bookmarks.length; i++){ //alert( bookmarks[i].id); bookmarkingSites += '<option value = "' + bookmarks[i].id + '">' + bookmarks[i].title + '</option>'; } return bookmarkingSites; }); } function socialbookmarksTableData(data) { var toAppend = ''; var bookmarkingSites = socialbookmarksGetBookmarkSites(); $.each(data.results, function(i, id){ var bookmarkCategories = socialbookmarksGetBookmarkCategories(data.results[i].bookmarkID); //rest of the code is not important }); $("#searchTable tbody").append(toAppend); }

  • Using boost::random as the RNG for std::random_shuffle

    - by Greg Rogers
    I have a program that uses the mt19937 random number generator from boost::random. I need to do a random_shuffle and want the random numbers generated for this to be from this shared state so that they can be deterministic with respect to the mersenne twister's previously generated numbers. I tried something like this: void foo(std::vector<unsigned> &vec, boost::mt19937 &state) { struct bar { boost::mt19937 &_state; unsigned operator()(unsigned i) { boost::uniform_int<> rng(0, i - 1); return rng(_state); } bar(boost::mt19937 &state) : _state(state) {} } rand(state); std::random_shuffle(vec.begin(), vec.end(), rand); } But i get a template error calling random_shuffle with rand. However this works: unsigned bar(unsigned i) { boost::mt19937 no_state; boost::uniform_int<> rng(0, i - 1); return rng(no_state); } void foo(std::vector<unsigned> &vec, boost::mt19937 &state) { std::random_shuffle(vec.begin(), vec.end(), bar); } Probably because it is an actual function call. But obviously this doesn't keep the state from the original mersenne twister. What gives? Is there any way to do what I'm trying to do without global variables?

  • PHP (A few questions) OO, refactoring, eclipse

    - by jax
    I am using PHP in eclipse. It works ok, I can connect to my remote site, there is colour coding of code elements and some code hints. I realise this may be too long to answer all questions, if you have a good answer for one part, answering just that is ok. Firstly General Coding I have found that it is easy to loose track of included files and their variables. For example if there was a database $cursor it is difficult to remember or even know that it was declared in the included file (this becomes much worse the more files you include). How are people dealing with this? How are people documenting their code - in particular the required GET and POST data? Secondly OO Development: Should I be going full OO in my development. Currently I have a functions library which I can include and have separated each "task" into a separate file. It is a bit nasty but it works. If I go OO how do I structure the directories in PHP, java uses packages - what about php? How should I name my files, should I use all lower case with _ for spaces "hello_world.php"? Should I name classes with Uppercase like Java "HelloWorld.php"? Is there a different naming convention for Classes and regular function files? Thirdly Refactoring I must say this is a real pain. If I change the name of a variable in one place I have to go through whole document and each file that included this file and change the name their too. Of course, errors everywhere is what results. How are people dealing with this problem? In Java if you change the name in one place it changes everywhere. Are there any plugins to improve php refactoring? I am using the official PHP version of Eclipse from their website. thanks

  • Fetching real time data from excel

    - by Umesh Sharma
    I am seriouly looking for your valuable help first time here. If possible, plese help me. I am developing a VB.NET app in which i read "real time data" from a excel sheet using "Microsoft.Office.Interop.Excel" i.e. excel automation. All cells in excel sheet are fetching stock data from some LOCAL DDE Server like "=XYZ|Bid!GOLD", "=XYZ|Bid!SILVER", "=XYZ|Ask!SILVER" and so on... Some cells also having fixed values like "Symbol", "Bid Rate", "32.90" etc. Values of DDE mapped cells (i.e. =XYZ|xxxx!yyy) are continuously changing. THE PROBLEM is here..."FIXED values" from excel cells are coming quite ok to my app but all DDE mapped cells values are coming "-2146826246" (When datasource local dde server ON) or "-2146826265" (OFF). Although, if i use C#.NET, it's all ok but not with Vb.NET. I want to display range of excel (A1 to J50) into VB.NET ListView which are changing in every 200ms (5 times in every 1 second) ================ Important ====================================================== Is it possible to BIND "listview items/columns values" with "excel cells" or some local memory variables ?? Currently, i am reading excel "cell by cell" and trying to put values in .NET listview but CPU USES are very high as well as it's toooo slow process. If yes, then how please ? I am a VFP developer but new to .NET It's very easy in VFP then why not in .NET ?? Please guide me, if someone has the solution...

  • Problem cube mapping in OpenGL using DDS compressed images

    - by Paul Jones
    Hi All, I am having trouble cube mapping when using a DDS cube map, I'm just getting a black cube which leads me to believe I have missing something simple, here's the code so far: DDS_IMAGE_DATA *pDDSImageData = LoadDDSFile(filename); //compressedTexture = -1; if(pDDSImageData != NULL) { int height = pDDSImageData->height; int width = pDDSImageData->width; int numMipMaps = pDDSImageData->numMipMaps; int blockSize; GLenum cubefaces[6] = { GL_TEXTURE_CUBE_MAP_POSITIVE_X, GL_TEXTURE_CUBE_MAP_NEGATIVE_X, GL_TEXTURE_CUBE_MAP_POSITIVE_Y, GL_TEXTURE_CUBE_MAP_NEGATIVE_Y, GL_TEXTURE_CUBE_MAP_POSITIVE_Z, GL_TEXTURE_CUBE_MAP_NEGATIVE_Z, }; if( pDDSImageData->format == GL_COMPRESSED_RGBA_S3TC_DXT1_EXT ) blockSize = 8; else blockSize = 16; glGenTextures( 1, &textureId ); int nSize; int nOffset = 0; glEnable(GL_TEXTURE_CUBE_MAP); glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_TEXTURE_MIN_FILTER, GL_LINEAR_MIPMAP_LINEAR); glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_TEXTURE_WRAP_R, GL_CLAMP_TO_EDGE); for(int face = 0; face < 6; face++) { for( int i = 0; i < numMipMaps; i++ ) { if( width == 0 ) width = 1; if( height == 0 ) height = 1; glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_GENERATE_MIPMAP, GL_TRUE); nSize = ((width+3)>>2) * ((height+3)>>2) * blockSize; glCompressedTexImage2D(cubefaces[face] , i, pDDSImageData->format, width, height, 0, nSize, pDDSImageData->pixels + nOffset ); nOffset += nSize; // Half the image size for the next mip-map level... width = (width / 2); height = (height / 2); } } } Once this code is called I bind the texture using glBindTexture and draw a cube using GL_QUADS and glTexCoord3f. Thank you for reading and all comments are welcome, sorry if any of the formatting comes out wrong.

  • DataTable vs. Collection in .Net

    - by B Pete
    I am writing a program that needs to read a set of records that describe the register map of a device I need to communicate with. Each record will have a handfull of fields that describe the properties of each register. I don't really need to edit or modify the data in my VB or C# program, though I would like to be able to display the data on a grid. I would like to store the data in a CSV file, or perhaps an XML file. I need to enable users to edit the data off-line, preferably in excel. I am considering using a DataTable or a Collection of "Register" objects (which I would define). I prototyped a DataTable, and found I can read/write XML easily using the built in methods and I can easily bind to a DataGridView. I was not able to find a way to retreive info on a single register without using a query that returns a collection of rows, even though I defined a unique primaty key column. The syntax to get a value from a column is also complex, though I could be missing something on both counts. I'm tempted to use a collection of "Register" objects that I can access via a unique key. It would be a little more coding up front, but seems like a cleaner solution overall. I should still be able to use LINQ to dataset to query subsets of registers when I need them, but would also be able to grab a single field using a the key value, something like this: Registers(keyValue).fieldName). Which would be a cleaner approach to the problem? Is there a way to read/write XML into a Collection without needing custom code? Could this be accomplished using String for a key?

  • Sql serve Full Text Search with Containstable is very slow when Used in JOIN!

    - by Bob
    Hello, I am using sql 2008 full text search and I am having serious issues with performance depending on how I use Contains or ContainsTable. Here are sample: (table one has about 5000 records and there is a covered index on table1 which has all the fields in the where clause. I tried to simplify the statements so forgive me if there is syntax issues.) Scenario 1: select * from table1 as t1 where t1.field1=90 and t1.field2='something' and Exists(select top 1 * from containstable(table1,*, 'something') as t2 where t2.[key]=t1.id) results: 10 second (very slow) Scenario 2: select * from table1 as t1 join containstable(table1,*, 'something') as t2 on t2.[key] = t1.id where t1.field1=90 and t1.field2='something' results: 10 second (very slow) Scenario 3: Declare @tbl Table(id uniqueidentifier primary key) insert into @tbl select {key] from containstable(table1,*, 'something') select * from table1 as t1 where t1.field1=90 and t1.field2='something' and Exists(select id from @tbl as tbl where id=req1.id) results: fraction of a second (super fast) Bottom line, it seems if I use Containstable in any kind of join or where clause condition of a select statement that also has other conditions, the performance is really bad. In addition if you look at profiler, the number of reads from the database goes to the roof. But if I first do the full text search and put results in a table variable and use that variable everything goes super fast. The number of reads are also much lower. It seems in "bad" scenarios, somehow it gets stuck in a loop which causes it to read many times from teh database but of course I don't understant why. Now the question is first of all whyis that happening? and question two is that how scalable table variables are? what if it results to 10s of thousands of records? is it still going to be fast. Any ideas? Thanks

  • Why do child elements cause 'dropleave' to be called (drag-n-drop file upload)?

    - by tundoopani
    I have a HTML5 drag-n-drop script that allows users to drop files in #droparea. The #droparea div has child elements that are also div elements. <div id="droparea"> <div id="showif_no_dragover">Drag files here!</div> <div id="showif_dragover">Drop the files!</div> </div> The associated javascript/jquery is: var droptarget = "#droparea"; $(droptarget).live('dragenter', dragEnter); $(droptarget).live('dragleave', dragExit); $(droptarget).live('dragover', nothing); $(droptarget).live('drop', dropGo); (Side question: should I use .live(), .on() or .bind() here?) I have created a sample jsFiddle with some additional code here: http://jsfiddle.net/PwFr9/3/ If you look at the console, you will notice that as you drag a file within #droparea, dragenter() and dragleave() are called multiple times, even though the drag is still inside #droparea. If you remove the child elements (#child1 and #child2), the problem is gone because the child elements are gone. How can I keep the child elements and prevent them from messing up the drag events? I have searched Stackoverflow and Google for hours without much help. I found this questions here at Stackoverflow: How to keep child elements from interfering with HTML5 dragover and drop events? I don't know why it works, though. I have tried placing 2 div elements on top of each other (via CSS positioning). The top-most div has the drag events attached whereas the bottom-most div has the child elements. I do not like this approach because it doesn't work with the rest of my page and does not allow mouse-click interaction with the bottom-most div. Any help is appreciated! Thank you in advance. Regards, tundoo

  • javascript - Detect if Google Analytics is loaded yet?

    - by Geuis
    I'm working on a project here that will store some info in Google Analytics custom variables. The script I'm building out needs to detect if GA has loaded yet before I can push data to it. The project is being designed to work across any kind of site that uses GA. The problem is reliably detecting if GA has finished loading or not and is available. A couple of variabilities here: 1) There's multiple methods of loading GA. Older scripts from the Urchin days up to the latest asynchronous scripts. Some of these are inline, some are asynchronous. Also, some sites do custom methods of loading GA, like at my job. We use YUI getScript to load it. 2) Variable-variable names. In some scripts, the variable name assigned to GA is "pageTracker". In others, its "_gaq". Then there's the infinity of custom variable names that sites could be using for their implementation of GA. So does anyone have any thoughts on what might be a reliable way to check if Google Analytics is being used on the page, and if it's been loaded?

  • ViewModel updates after Model server roundtrip

    - by Pavel Savara
    I have stateless services and anemic domain objects on server side. Model between server and client is POCO DTO. The client should become MVVM. The model could be graph of about 100 instances of 20 different classes. The client editor contains diverse tab-pages all of them live-connected to model/viewmodel. My problem is how to propagate changes after server round-trip nice way. It's quite easy to propagate changes from ViewModel to DTO. For way back it would be possible to throw away old DTO and replace it whole with new one, but it will cause lot of redrawing for lists/DataTemplates. I could gather the server side changes and transmit them to client side. But the names of fields changed would be domain/DTO specific, not ViewModel specific. And the mapping seems nontrivial to me. If I should do it imperative way after round-trip, it would break SOC/modularity of viewModels. I'm thinking about some kind of mapping rule engine, something like automappper or emit mapper. But it solves just very plain use-cases. I don't see how it would map/propagate/convert adding items to list or removal. How to identify instances in collections so it could merge values to existing instances. As well it should propagate validation/error info. Maybe I should implement INotifyPropertyChanged on DTO and try to replay server side events on it ? And then bind ViewModel to it ? Would binding solve the problems with collection merges nice way ? Is EventAgregator from PRISM useful for that ? Is there any event record-replay component ? Is there better client side pattern for architecture with server side logic ?

  • What is the best way to automatically transpose a LilyPond source file into multiple keys?

    - by Michael Steele
    problem I'm using LilyPond to typeset sheet music for a church choir to perform. Depending on who is available on any given week, songs will be played in various keys. We have an amazing pianist who can play anything we throw at her and the guitarists will typically pencil in alternate chords, but I want to make things easier by having beautifully typeset sheet music available in any key we want. So say we're going to sing our ABCs. First I'll take whatever source transcriptions available and enter it into a LilyPond script: melody = \relative c' { c c g g a a g2 f f e e d d c2 } I want the ability to transpose this automatically, so if I want the whole thing in 'G' I wrap the song in a \transpose call like so: melody = \transpose c g \relative c' { c c g g a a g2 f f e e d d c2 } What I really want is to substitute something for the 'g' and generate the output for melody multiple times. Simple LilyPond variables don't seem to work here, and so far I've been unsuccessful in defining a scheme function to do this. What I've resorted to for the moment is taking the above file, call it twinkle.ly and turning it into an M4 script called twinkle.ly.m4, the contents of which look like this: melody = \transpose c _key \relative c' { c c g g a a g2 f f e e d d c2 } I then compile the while thing by executing the following line: > m4 -D _key=g twinkle.ly.m4 > twinkle_g.ly && lilypond twinkle_g.ly I've written a Makefile to do this for me, defining rules for every song I have and every key I'm interested in. question There's got to be a better way of going about this. Given that Lilypond supports embedded scheme, I would prefer to not use a macro preprocessed on it. Has anybody else come up with a solution to this same problem?

  • jQuery and MooTools Conflict

    - by flipflopmedia
    Okay, so I got jQuery to get along with MooTools with one script, by adding this at the top of the jQuery script: var $j = jQuery.noConflict(); and then replacing every: $( with $j( But how would you get MooTools to like the following script that using jQuery??

  • Sending jQuery.ajax data simultaneous to a form submit

    - by dscher
    I have a bit of a conundrum. I have a form which has numerous fields. There is one field for links where you enter a link, click an add button, and the link(using jQuery) gets added to a link_array. I want this array to be sent via the jQuery.ajax method when the form is submitted. If I send the link_array using $.ajax like this: $.ajax({ type: "POST", url: "add_stock", dataType: "json", data: { "links": link_array } }); when the add link button is selected the data goes no problem to the correct place and gets put in the db correctly. If I bind the above function to the submit form button using $(#stock_form).submit(..... then the rest of the form data is sent but not the link_array. I can obviously pass the link array back into a hidden field in HTML but then I'd have to unpack the array into comma separate values and break the comma-separated string apart in PHP. It just seems 100X easier to unpack the Javascript array in PHP without an other fuss. So, how is it that you can send an array from javascript using $.ajax concurrent to the rest of the $_POST data in HTML? Please note that I'm using Kohana 3.0 framework but really that shouldn't make a difference, what I want to do is add this js array to the $_POST array that is already going. Thanks!

  • How do I use Perl's WWW::Facebook::API to publish to a user's newsfeed?

    - by Russell C.
    We use Facebook Connect on our site in conjunction with the WWW::Facebook::API CPAN module to publish to our users newsfeed when requested by the user. So far we've been able to successfully update the user's status using the following code: use WWW::Facebook::API; my $facebook = WWW::Facebook::API->new( desktop => 0, api_key => $fb_api_key, secret => $fb_secret, session_key => $query->cookie($fb_api_key.'_session_key'), session_expires => $query->cookie($fb_api_key.'_expires'), session_uid => $query->cookie($fb_api_key.'_user') ); my $response = $facebook->stream->publish( message => qq|Test status message|, ); However, when we try to update the code above so we can publish newsfeed stories that include attachments and action links as specified in the Facebook API documentation for Stream.Publish, we have tried about 100 different ways without any success. According to the CPAN documentation all we should have to do is update our code to something like the following and pass the attachments & action links appropriately which doesn't seem to work: my $response = $facebook->stream->publish( message => qq|Test status message|, attachment => $json, action_links => [@links], ); For example, we are passing the above arguments as follows: $json = qq|{ 'name': 'i\'m bursting with joy', 'href': ' http://bit.ly/187gO1', 'caption': '{*actor*} rated the lolcat 5 stars', 'description': 'a funny looking cat', 'properties': { 'category': { 'text': 'humor', 'href': 'http://bit.ly/KYbaN'}, 'ratings': '5 stars' }, 'media': [{ 'type': 'image', 'src': 'http://icanhascheezburger.files.wordpress.com/2009/03/funny-pictures-your-cat-is-bursting-with-joy1.jpg', 'href': 'http://bit.ly/187gO1'}] }|; @links = ["{'text':'Link 1', 'href':'http://www.link1.com'}","{'text':'Link 2', 'href':'http://www.link2.com'}"]; The above, nor any of the other representations we tried seem to work. I'm hoping some other perl developer out there has this working and can explain how to create the attachment and action_links variables appropriately in Perl for posting to the Facebook news feed through WWW::Facebook::API. Thanks in advance for your help!
