  • Close application on error

    - by poke
    I’m currently writing an application for the Android platform that requires a mounted SD card (or ExternalStorage). I know that it might not be the best way to require something like that, but the application will work with quite a lot of data, and I don’t even want to think about storing that on the device’s storage. Anyway, to ensure that the application won’t run without the external storage, I do a quick check in the activity’s onCreate method. If the card is not mounted, I want to display an error message and then quit the application. My current approach looks like this: public void onCreate ( Bundle savedInstanceState ) { super.onCreate( savedInstanceState ); setContentView( R.layout.main ); try { // initialize data storage // will raise an exception if it fails, or the SD card is not mounted // ... } catch ( Exception e ) { AlertDialog.Builder builder = new AlertDialog.Builder( this ); builder .setMessage( "There was an error: " + e.getMessage() ) .setCancelable( false ) .setNeutralButton( "Ok.", new DialogInterface.OnClickListener() { public void onClick ( DialogInterface dialog, int which ) { MyApplication.this.finish(); } } ); AlertDialog error = builder.create(); error.show(); return; } // continue ... } When I run the application, and the exception gets raised (I raise it manually to check if everything works), the error message is displayed correctly. However when I press the button, the application closes and I get an Android error, that the application was closed unexpectedly (and I should force exit). I read some topics before on closing an application, and I know that it maybe shouldn’t happen like that. But how should I instead prevent the application from continuing to run? How do you close the application correctly when an error occurs?

  • Calling a method on an unitialized object (null pointer)

    - by Florin
    What is the normal behavior in Objective-C if you call a method on an object (pointer) that is nil (maybe because someone forgot to initialize it)? Shouldn't it generate some kind of an error (segmentation fault, null pointer exception...)? If this is normal behavior, is there a way of changing this behavior (by configuring the compiler) so that the program raises some kind of error / exception at runtime? To make it more clear what I am talking about, here's an example. Having this class: @interface Person : NSObject { NSString *name; } @property (nonatomic, retain) NSString *name; - (void)sayHi; @end with this implementation: @implementation Person @synthesize name; - (void)dealloc { [name release]; [super dealloc]; } - (void)sayHi { NSLog(@"Hello"); NSLog(@"My name is %@.", name); } @end Somewhere in the program I do this: Person *person = nil; //person = [[Person alloc] init]; // let's say I comment this line person.name = @"Mike"; // shouldn't I get an error here? [person sayHi]; // and here [person release]; // and here

  • jquery pagination plugin problem

    - by John the horn
    I am using a pagination plugin called "pagination". Here is the script that is initialized : function pageselectCallback(page_index, jq){ var new_content = jQuery('#hiddenresult div.result:eq('+page_index+')').clone(); $('#Searchresult').empty().append(new_content); return false; } /** * Initialisation function for pagination */ function initPagination() { // count entries inside the hidden content var num_entries = jQuery('#hiddenresult div.result').length; // Create content inside pagination element $("#Pagination").pagination(num_entries, { callback: pageselectCallback, items_per_page:1 // Show only one item per page }); } // When document is ready, initialize pagination $(document).ready(function(){ initPagination(); }); and I am using this script for accordation on the page : <script type="text/javascript"> $(document).ready(function(){ $('#content').show(); $('#content1').hide(); $('#content2').hide(); $('#content3').hide(); $('#content4').hide(); $('#content5').hide(); $('a.bucatarii_serie').click(function(){ $("div[id^='content']").hide(); $('#content').toggle('slow'); }); $('a.livinguri_serie').click(function(){ $("div[id^='content']").hide(); $('#content1').toggle('slow'); }); $('a.dormitoare_serie').click(function(){ $("div[id^='content']").hide(); $('#content2').toggle('slow'); }); $('a.tratamente').click(function(){ $("div[id^='content']").hide(); $('#content3').toggle('slow'); }); $('a.chirurgie').click(function(){ $("div[id^='content']").hide(); $('#content4').toggle('slow'); }); $('a.frizerie').click(function(){ $("div[id^='content']").hide(); $('#content5').toggle('slow'); }); }); </script> My problem is that I don't know how to implement multiple paginations on the same page in diferent containers but in a bigger container.

  • How to build a JSON response by combining @foo.to_json(options) and @bars.to_json(options) in Rails

    - by smotchkkiss
    First, the desired result I have User and Item models. I'd like to build a JSON response that looks like this: { "user": {"username":"Bob!","foo":"whatever","bar":"hello!"}, "items": [ {"id":1, "name":"one", "zim":"planet", "gir":"earth"}, {"id":2, "name":"two", "zim":"planet", "gir":"mars"} ] } However, my User and Item model have more attributes than just those. I found a way to get this to work, but beware, it's not pretty... Please help... My hacks home_controller.rb class HomeController < ApplicationController def observe respond_to do |format| format.js { render :json => Observation.new(current_user, @items).to_json } end end end observation.rb # NOTE: this is not a subclass of ActiveRecord::Base # this class just serves as a container to aggregate all "observable" objects class Observation attr_accessor :user, :items def initialize(user, items) self.user = user self.items = items end # The JSON needs to be decoded before it's sent to the `to_json` method in the home_controller otherwise the JSON will be escaped... # What a mess! def to_json { :user => ActiveSupport::JSON.decode(user.to_json(:only => :username, :methods => [:foo, :bar])), :items => ActiveSupport::JSON.decode(auctions.to_json(:only => [:id, :name], :methods => [:zim, :gir])) } end end

  • log4js ConsoleAppender initialization

    - by perrierism
    I'm wondering if anyone happens to have some experience using Log4js? It seems its normal ConsoleAppender isn't always ready to use immediately after it's added to a logger object... If I have two sequential script tags in a document like: //Initialize logger <script type="text/javascript"> var logger = new Log4js.getLogger("JSLOG"); logger.addAppender(new Log4js.ConsoleAppender(logger, false)); logger.setLevel(Log4js.Level.INFO); </script> //Use logger <script type="text/javascript"> logger.info('Test test'); </script> ... It causes the console pop-up (pop-up window) to appear with an error message on page load: 12:58:23 PM WARN Log4js - Could not run the listener function () { return fn.apply(object, arguments); }. TypeError: this.outputElement is null The console is still initialised, it's there afterward, but for just that first logger call it doesn't seem to be there fully. If I make the first logger call setTimeout("logger.info('test test')", 1000), it doesn't have the error. So it's like it's not ready immediately. Anyone see this before or know what a workaround might be? Cheers

  • Copy vector of values to vector of pairs in one line

    - by Kirill V. Lyadvinsky
    I have the following types: struct X { int x; X( int val ) : x(val) {} }; struct X2 { int x2; X2() : x2() {} }; typedef std::pair<X, X2> pair_t; typedef std::vector<pair_t> pairs_vec_t; typedef std::vector<X> X_vec_t; I need to initialize instance of pairs_vec_t with values from X_vec_t. I use the following code and it works as expected: int main() { pairs_vec_t ps; X_vec_t xs; // this is not empty in the production code ps.reserve( xs.size() ); { // I want to change this block to one line code. struct get_pair { pair_t operator()( const X& value ) { return std::make_pair( value, X2() ); } }; std::transform( xs.begin(), xs.end(), back_inserter(ps), get_pair() ); } return 0; } What I'm trying to do is to reduce my copying block to one line with using boost::bind. This code is not working: for_each( xs.begin(), xs.end(), boost::bind( &pairs_vec_t::push_back, ps, boost::bind( &std::make_pair, _1, X2() ) ) ); I know why it is not working, but I want to know how to make it working without declaring extra functions and structs?

  • Origin null is not allowed by Access-Control-Allow-Origin

    - by JIGGABITS
    I'm currently working with the SoundCloud API and would like to have a track embed when a button is clicked. I get two errors: XMLHttpRequest cannot load http://soundcloud.com/oembed.json?url=http%3A%2F%2Fapi.soundcloud.com%2Ftracks%2F48419073. Origin null is not allowed by Access-Control-Allow-Origin. AND Uncaught TypeError: Cannot read property 'html' of null Here is my code: <button onclick="getPopular()">+1</button> <div id="track"></div> <script src="http://connect.soundcloud.com/sdk.js" type="text/JavaScript"></script> <script type="text/JavaScript"> SC.initialize({ client_id: "**************", }); var getPopular = function() { SC.get("/tracks", {limit: 1}, function(tracks) { var track = tracks[0]; alert("Latest track: " + track.title); SC.oEmbed(track.uri, document.getElementById("track")); }); }; </script> I use an alert in my code to let me know that it is actually taking information from the SoundCloud API. I'm just not sure what else is preventing it from embedding. Thanks, ahead of time, or looking at my question. jiggabits

  • Flex 3 Close UrlLoader throws exception

    - by gmoniey
    I am trying to simulate a 'HEAD' method using UrlLoader; essentially, I just want to check for the presence of a file without downloading the entire thing. I figured I would just use HttpStatusEvent, but the following code throws an exception (one that I can't wrap in a try/catch block) when you run in debug mode. <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" initialize="init()"> <mx:Script> <![CDATA[ private static const BIG_FILE:String = "http://www.archive.org/download/gspmovvideotestIMG0021mov/IMG_0021.mov"; private var _loader:URLLoader; private function init():void { _loader = new URLLoader(); _loader.addEventListener(HTTPStatusEvent.HTTP_STATUS, statusHandler); _loader.addEventListener(IOErrorEvent.IO_ERROR, errorHandler); _loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, errorHandler); _loader.load(new URLRequest(BIG_FILE)); } public function unload():void { try { _loader.close(); _loader.removeEventListener(HTTPStatusEvent.HTTP_STATUS, statusHandler); _loader.removeEventListener(IOErrorEvent.IO_ERROR, errorHandler); _loader.removeEventListener(SecurityErrorEvent.SECURITY_ERROR, errorHandler); } catch(error:Error) { status.text = error.message; } } private function errorHandler(event:Event):void { status.text = "error"; unload(); } private function statusHandler(event:HTTPStatusEvent):void { if(event.status.toString().match(/^2/)) { status.text = "success"; unload(); } else { errorHandler(event); } } ]]> </mx:Script> <mx:Label id="status" /> I tried using ProgressEvents instead, but it seems that some 404 pages return content, so the status event will correctly identify if the page exists. Anyone have any ideas?

  • ASP.Net HttpModule List<> content

    - by test
    We have created an http module that loads data on initialize into a list, and uses that list on every endrequest event of application. However we got a null reference exception on the module at endRequest event complaining that the content is null. Yet we are sure that at module initialization we have put non-null objects correctly. How is this possible? Any ideas? Thanks in advance. The place where i fill the data into the list what named as "Pages" : using (SqlDataReader reader = cmd.ExecuteReader()) { while (reader.Read()) { LandingPageDetails details = new LandingPageDetails(); details.DomainId = Convert.ToInt32(reader["DomainId"]); details.PageId = Convert.ToInt32(reader["TrackingPageId"]); details.PageAddress = Convert.ToString(reader["PageAddress"]); if (!string.IsNullOrEmpty(details.PageAddress)) { Pages.Add(details); } } } // Find the related record on EndRequesst event LandingPageDetails result = Pages.Find ( delegate(LandingPageDetails current) { return current.PageAddress.Equals(url, StringComparison.InvariantCultureIgnoreCase); } ); The line what we get the error return current.PageAddress.Equals(url, StringComparison.InvariantCultureIgnoreCase); "current" is the null object P.S : It works properly, but one day later contents become null. Possibly, there is something wrong on IIS. Our server is Windows 2003, IIS 6.0

  • Polymorphic Queue

    - by metdos
    Hello Everyone, I'm trying to implement a Polymorphic Queue. Here is my trial: QQueue <Request *> requests; while(...) { QString line = QString::fromUtf8(client->readLine()).trimmed(); if(...)){ Request *request=new Request(); request->tcpMessage=line.toUtf8(); request->decodeFromTcpMessage(); //this initialize variables in request using tcpMessage if(request->requestType==REQUEST_LOGIN){ LoginRequest loginRequest; request=&loginRequest; request->tcpMessage=line.toUtf8(); request->decodeFromTcpMessage(); requests.enqueue(request); } //Here pointers in "requests" do not point to objects I created above, and I noticed that their destructors are also called. LoginRequest *loginRequest2=dynamic_cast<LoginRequest *>(requests.dequeue()); loginRequest2->decodeFromTcpMessage(); } } Unfortunately, I could not manage to make work Polymorphic Queue with this code because of the reason I mentioned in second comment.I guess, I need to use smart-pointers, but how? I'm open to any improvement of my code or a new implementation of polymorphic queue. Thanks.

  • In facebook connect, how can I check if a user is a fan of my facebook page? Is it possible to track

    - by Tony
    I am trying to determine if a user is a facebook fan. I load the facebook JS library and initialize: <script type="text/javascript" src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US"></script> FB_RequireFeatures(["XFBML","Connect","Api"], function() { FB.init("my_api_key","xd_receiver.htm") }); FB.ensureInit(function () { FB.ApiClient.pages_isFan(my_profile_id,"some_UID",callback); }); However when I call the API client with FB.ApiClient.pages_isFan, I get a JS error - FB.ApiClient is undefined I am also using the FBML fan tag to display the "become a fan" button: <fb:fan profile_id="my_profile_id" stream="0" connections="10" logobar="1" width="300"></fb:fan> And would like to be notified when either the "become a fan" button is clicked or a user has successfully become a fan. The business logic is pretty simple - If they become a fan, track it in my database. Then if they try to become a fan again, check with the library if they are a fan and say "You are already a fan" if they are a fan, show the widget if not.

  • jquery ready function: script not detecting a function

    - by deostroll
    There is a web page with place holder (a normal div). Via ajax calls I am loading a <form> and a <script> into the place holder. The script contains necessary javascript to initialize the form (i.e. for e.g. disable the controls so as to make form read-only, etc). Here is a piece of code I have; it works, but the commented part doesn't work. Because the script engine cannot find the object tristate_DisableControl which is a function in one of those scripts I call via ajax. $(document).ready(function() { // $('#site_preferences_content div').each(function() { // if (typeof (window.tristate_DisableControl) == 'undefined') { // if (typeof (window.console) != 'undefnied') // console.log((new Date()).toTimeString() + ' not logable'); // pausecomp(1000); // } // else // tristate_DisableControl(this); // }); //end $('#site_prefrences_content div').each() setTimeout(function() { $('#site_preferences_content div').each(function() { tristate_DisableControl(this); }) }, 1000); }); I thought by the time $(document).ready() executes the DOM will be properly loaded...

  • How to change the view angle and label value of a chart .NET C#

    - by George
    Short Description I am using charts for a specific application where i need to change the view angle of the rendered 3D Pie chart and value of automatic labels from pie label names to corresponding pie values. This how the chart looks: Initialization This is how i initialize it: Dictionary<string, decimal> secondPersonsWithValues = HistoryModel.getSecondPersonWithValues(); decimal[] yValues = new decimal[secondPersonsWithValues.Values.Count]; //VALUES string[] xValues = new string[secondPersonsWithValues.Keys.Count]; //LABELS secondPersonsWithValues.Keys.CopyTo(xValues, 0); secondPersonsWithValues.Values.CopyTo(yValues, 0); incomeExpenseChart.Series["Default"].ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Pie; incomeExpenseChart.Series["Default"].Points.DataBindXY(xValues, yValues); incomeExpenseChart.ChartAreas["Default"].Area3DStyle.Enable3D = true; incomeExpenseChart.Series["Default"].CustomProperties = "PieLabelStyle=Outside"; incomeExpenseChart.Legends["Default"].Enabled = true; incomeExpenseChart.ChartAreas["Default"].Area3DStyle.LightStyle = System.Windows.Forms.DataVisualization.Charting.LightStyle.Realistic; incomeExpenseChart.Series["Default"]["PieDrawingStyle"] = "SoftEdge"; Basically i am querying data from database using the HistoryModel.getSecondPersonWithValues(); to get pairs as Dictionary<string, decimal> where key is the person and value is ammount. Problem #1 What i need is to be able to change the marked labels from person names to the ammounts or add another label of ammounts with the same colors (See Image). Problem #2 Another problem is that i need to change the view angle of 3D Pie chart. Maybe it's very simple and I just don't know the needed property or maybe i need to override some paint event. Either ways any kind of ways would be appriciated. Thanks in advance George.

  • How do I get my code to read the spaces between longs?

    - by WahtsUpWorld
    I apologize for any inconvenience that may occur in answering my question, I'm fairly new to programming and I'm so far only in the last weeks of my community college Java I class. The problem I am facing is in my code of which I cannot seem to get the PrintWriter to address the spaces in between my longs' phone number and social security I.D. The entire code consists of two classes in which one pulls from the other the information needed to parse and present the file writer/print writer. Here is the entire code w/ the second class after it: public class FinalProjectGroup1 { public static void main(String[] args) { } public String name; public long ssid; public double pay; public String address;

Where, as previously mentioned, the long's phone number and social security I.D. don't show the spaces in the text file.

  • Google Maps API V3: How to jump to a specific marker from outside the map?

    - by Tom
    I have a map with two markers on it. The initial view of the map only shows one marker, and I want to provide a link next to the map that will move the map to the 2nd marker when clicked. Here's a demo of what I want, using v2 of the API: http://arts.brighton.ac.uk/contact-university-of-brighton-faculty-of-arts (note the links below the map) Here's what I have so far: <script type="text/javascript"> function initialize() { var latlng = new google.maps.LatLng(50.823817, -0.135634); var myOptions = { zoom: 13, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP, mapTypeControlOptions: { style: google.maps.MapTypeControlStyle.DROPDOWN_MENU } , scaleControl: false }; var map = new google.maps.Map(document.getElementById("map"), myOptions); // 1st marker var marker1 = new google.maps.Marker({ position: new google.maps.LatLng(50.823817, -0.135634), map: map, title: 'my title' }); var infowindow = new google.maps.InfoWindow({ content: 'my window content' }); google.maps.event.addListener(marker1, 'click', function() { infowindow.open(map, marker1); }); // 2nd marker var marker2 = new google.maps.Marker({ position: new google.maps.LatLng(51.5262405, -0.074549), map: map, title: 'my 2nd title'}); var infowindow2 = new google.maps.InfoWindow({ content: 'content for my 2nd window' }); google.maps.event.addListener(marker2, 'click', function() { infowindow2.open(map, marker2); }); } </script> So what I'd like to add is a link to marker2, to move the map some 50-odd miles up, e.g. <a href="#marker2">Second location</a>. How would I do this?

  • Best Practice With JFrame Constructors?

    - by David Barry
    In both my Java classes, and the books we used in them laying out a GUI with code heavily involved the constructor of the JFrame. The standard technique in the books seems to be to initialize all components and add them to the JFrame in the constructor, and add anonymous event handlers to handle events where needed, and this is what has been advocated in my class. This seems to be pretty easy to understand, and easy to work with when creating a very simple GUI, but seems to quickly get ugly and cumbersome when making anything other than a very simple gui. Here is a small code sample of what I'm describing: public class FooFrame extends JFrame { JLabel inputLabel; JTextField inputField; JButton fooBtn; JPanel fooPanel; public FooFrame() { super("Foo"); fooPanel = new JPanel(); fooPanel.setLayout(new FlowLayout()); inputLabel = new JLabel("Input stuff"); fooPanel.add(inputLabel); inputField = new JTextField(20); fooPanel.add(inputField); fooBtn = new JButton("Do Foo"); fooBtn.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { //handle event } }); fooPanel.add(fooBtn); add(fooPanel, BorderLayout.CENTER); } } Is this type of use of the constructor the best way to code a Swing application in java? If so, what techniques can I use to make sure this type of constructor is organized and maintainable? If not, what is the recommended way to approach putting together a JFrame in java?

  • Is there a good way to QuickCheck Happstack.State methods?

    - by Paul Kuliniewicz
    I have a set of Happstack.State MACID methods that I want to test using QuickCheck, but I'm having trouble figuring out the most elegant way to accomplish that. The problems I'm running into are: The only way to evaluate an Ev monad computation is in the IO monad via query or update. There's no way to create a purely in-memory MACID store; this is by design. Therefore, running things in the IO monad means there are temporary files to clean up after each test. There's no way to initialize a new MACID store except with the initialValue for the state; it can't be generated via Arbitrary unless I expose an access method that replaces the state wholesale. Working around all of the above means writing methods that only use features of MonadReader or MonadState (and running the test inside Reader or State instead of Ev. This means forgoing the use of getRandom or getEventClockTime and the like inside the method definitions. The only options I can see are: Run the methods in a throw-away on-disk MACID store, cleaning up after each test and settling for starting from initialValue each time. Write the methods to have most of the code run in a MonadReader or MonadState (which is more easily testable), and rely on a small amount of non-QuickCheck-able glue around it that calls getRandom or getEventClockTime as necessary. Is there a better solution that I'm overlooking?

  • FluentValidation + s#arp

    - by csetzkorn
    Hi, Did someone implement something like this: http://www.jeremyskinner.co.uk/2010/02/22/using-fluentvalidation-with-an-ioc-container/ in s#arp? Thanks. Christian PS: Hi, I have made a start in using FluentValidation in S#arp. I have implemented a Validator factory: public class ResolveType { private static IWindsorContainer _windsorContainer; public static void Initialize(IWindsorContainer windsorContainer) { _windsorContainer = windsorContainer; } public static object Of(Type type) { return _windsorContainer.Resolve(type); } } public class CastleWindsorValidatorFactory : ValidatorFactoryBase { public override IValidator CreateInstance(Type validatorType) { return ResolveType.Of(validatorType) as IValidator; } } I think I will use services which can be used by the controllers etc.: public class UserValidator : AbstractValidator { private readonly IUserRepository UserRepository; public UserValidator(IUserRepository UserRepository) { Check.Require(UserRepository != null, "UserRepository may not be null"); this.UserRepository = UserRepository; RuleFor(user => user.Email).NotEmpty(); RuleFor(user => user.FirstName).NotEmpty(); RuleFor(user => user.LastName).NotEmpty(); } } public interface IUserService { User CreateUser(User User); } public class UserService : IUserService { private readonly IUserRepository UserRepository; private readonly UserValidator UserValidator; public UserService ( IUserRepository UserRepository ) { Check.Require(UserRepository != null, "UserRepository may not be null"); this.UserRepository = UserRepository; this.UserValidator = new UserValidator(UserRepository); } public User CreateUser(User User) { UserValidator.Validate(User); ... } } Instead of putting concrete validators in the service, I would like to use the above factory somehow. Where do I register it and how in s#arp (Global.asax)? I believe s#arp is geared towards the nhibernator validator. How do I deregister it? Thanks. Best wishes, Christian

  • How to implement "business rules" in Rails?

    - by Zabba
    What is the way to implement "business rules" in Rails? Let us say I have a car and want to sell it: car = Cars.find(24) car.sell car.sell method will check a few things: does current_user own the car? check: car.user_id == current_user.id is the car listed for sale in the sales catalog? check: car.catalogs.ids.include? car.id if all o.k. then car is marked as sold. I was thinking of creating a class called Rules: class Rules def initialize(user,car) @user = user @car = car end def can_sell_car? @car.user_id == @user.id && @car.catalogs.ids.include? @car.id end end And using it like this: def Car def sell if Rules.new(current_user,self).can_sell_car ..sell the car... else @error_message = "Cannot sell this car" nil end end end As for getting the current_user, I was thinking of storing it in a global variable? I think that whenever a controller action is called, it's always a "fresh" call right? If so then storing the current user as a global variable should not introduce any risks..(like some other user being able to access another user's details) Any insights are appreciated! UPDATE So, the global variable route is out! Thanks to PeterWong for pointing out that global variables persist! I've now thinking of using this way: class Rules def self.can_sell_car?(current_user, car) ......checks.... end end And then calling Rules.can_sell_car?(current_user,@car) from the controller action. Any thoughts on this new way?

  • How to set connection string dynamically in NHibernate

    Hi I want assign connection string for NHibernate using following code and getting exception (bold). log4net.Config.DOMConfigurator.Configure(); Configuration config = new Configuration(); IDictionary props = new Hashtable(); props["hibernate.connection.provider"] = "NHibernate.Connection.DriverConnectionProvider"; props["hibernate.dialect"] = "NHibernate.Dialect.MsSql2000Dialect"; props["hibernate.connection.driver_class"] = "NHibernate.Driver.SqlClientDriver"; props["hibernate.connection.connection_string"] = @"Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=Sample;Data Source=HYDHTC92318D\SQLEXPRESS"; props["hibernate.connection.current_session_context_class"] = "web"; props["hibernate.connection.show_sql"] = "true"; props["hibernate.connection.proxyfactoryfactory.factory_class"] = "NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle"; foreach (DictionaryEntry de in props) { config.SetProperty(de.Key.ToString(), de.Value.ToString()); } config.AddAssembly("nhibernator"); factory = config.BuildSessionFactory(); session = factory.OpenSession(); The ProxyFactoryFactory was not configured. Initialize 'proxyfactory.factory_class' property of the session-factory configuration section with one of the available NHibernate.ByteCode providers.

  • Detect NetStream events with AS3 Video Object (not component)

    - by JFOX
    I have created a FLV video player using the AS3 flash.media.Video object (not the FLV playback component) and I am trying to listen for meta events and Cue Points embedded in the FLV video but I am not receiving any when I trace the movie. The cue points are not being created dynamically, they are in the FLV video. Video embed code: // Initialize net stream nc = new NetConnection(); nc.connect (null); // Not using a media server. ns = new NetStream(nc); // Add video to stage vid = new Video(456,675); addChild (vid); // Add callback method for listening on // NetStream meta data client = new Object(); ns.client = client; client.onMetaData = this.nsMetaDataCallback; client.onCuePoint = this.onCuePoint; // Play video vid.attachNetStream ( ns ); ns.play ("flv/00_010.flv"); callback handlers in the same class as the above code: public function onCuePoint(info:Object):void { trace("cuePoint: time = " + info.time + " name = " + info.name + " type = " + info.type); if (ns) ns.pause(); } public function nsMetaDataCallback (mdata:Object):void { trace (mdata.duration); } Is there anything I am missing have wrong to capture events from my net stream?

  • Having trouble plugging jQuery FullCalendar into Squarespace page

    - by ellenchristine
    When I test the fullcalendar widget locally, it works fine. However, when I try to integrate it with Squarespace, it doesn't show up. Here is what is in my head tag: <link rel='stylesheet' type='text/css' href='storage/scripts/fullcalendar.css' /> <script type='text/javascript' src='storage/scripts/jquery.js'></script> <script type='text/javascript' src='storage/scripts/fullcalendar.js'></script> <script type='text/javascript'> $(document).ready(function() { // page is now ready, initialize the calendar... $('#calendar').fullCalendar({ aspectRatio:2 }) }); </script> I have this in my body tag: <div id="calendar" style="width:500px; height:330px; background-color:#CCCCCC;"></div> The div displays but the calendar doesn't appear at all. I can't figure out why this isn't working! The calendar should definitely fit in the div space (at least it does locally). I've used jQuery with Squarespace before, and I don't see where my error is.

  • Loading 2 Singletons With Dependencies when an app is opened (appDelegate / appDidBecomeActive) iPhone SDK

    - by taber
    I'm trying to load two standard-issue style singletons: http://cocoawithlove.com/2008/11/singletons-appdelegates-and-top-level.html when my iPhone app is loaded. Here's my code: - (void) applicationDidFinishLaunching:(UIApplication *)application { // first, restore user prefs [AppState loadState]; // then, initialize the camera [[CameraModule sharedCameraModule] initCamera]; } My "camera module" has code that checks a property of the AppState singleton. But I think what's happening is a race condition where the camera module singleton is trying to access the AppState property while it's in the middle of being initialized (so the property is nil, and it's re-initializing AppState). I'd really like to keep these separate, instead of just throwing one (or both) into the App Delegate. Has anyone else seen something like this? What kind of workaround did you use, or what would you suggest? Thanks in advance! Here's the loadState method: + (void)loadState { @synchronized([AppState class]) { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *file = [documentsDirectory stringByAppendingPathComponent:@"prefs.archive"]; Boolean saveFileExists = [[NSFileManager defaultManager] fileExistsAtPath:file]; if(saveFileExists) { sharedAppState = [[NSKeyedUnarchiver unarchiveObjectWithFile:file] retain]; } else { [AppState sharedAppState]; } } }

  • Access reading error when using class member variable

    - by bsg
    Hi, I have a class with private member variables declared in a header file. In my constructor, I pass in some filenames and create other objects using those names. This works fine. When I try to add another member variable, however, and initialize it in the constructor, I get an access reading violation. I sent the code to someone else and it works fine on his computer. Any idea what could be wrong? Here is the offending code: The .h file: class QUERYMANAGER { INDEXCACHE *cache; URLTABLE *table; SNIPPET *snip; int* iquery[MAX_QUERY_LENGTH]; int* metapointers[MAX_QUERY_LENGTH]; int blockpointers[MAX_QUERY_LENGTH]; int docpositions[MAX_QUERY_LENGTH]; int numberdocs[MAX_QUERY_LENGTH]; int frequencies[MAX_QUERY_LENGTH]; int docarrays[MAX_QUERY_LENGTH][256]; int qsize; public: QUERYMANAGER(); QUERYMANAGER(char *indexfname, char *btfname, char *urltablefname, char *snippetfname, char *snippetbtfname); ~QUERYMANAGER(); This is the .cpp file: #include "querymanagernew.h" #include "snippet.h" using namespace std; QUERYMANAGER::QUERYMANAGER(char *indexfname, char *btfname, char *urltablefname, char *snippetfname, char *snippetbtfname){ cache = new INDEXCACHE(indexfname, btfname); table = new URLTABLE(urltablefname); snip = new SNIPPET(snippetfname, snippetbtfname); //this is where the error occurs qsize = 0; } I am totally at a loss as to what is causing this - any ideas? Thanks, bsg
