• Phonegap Android application exiting - but not really - when home button is pressed

  - by Lucas T

  I have created an Phonegap 1.5/Android application. My client reports that, when he leaves the app using the Home button, and then relaunches it using the app icon, the app relaunches from the start instead of resuming. However, when he holds the home button, the app appears in the running apps, and when he accesses the app through this menu, the app resumes in the expected way. I thought this could be linked to the app being automatically closed by the OS due to a lack of memory, but if that was the case the app shouldn't appear in the running apps. I could not reproduce the bug on my Sony Ericsson XPERIA with Android 2.3.4, the client has experienced this behaviour on a Motorola Defy and on another phone (i'll add the reference of the other phone and the OS versions as soon as I get them). The initialization process of the app is declared this way : window.addEventListener('load', function(){ document.addEventListener('deviceready', _onDeviceReady, false); }, false); Could this be fixed by attaching the processes to other events (although I doubt it, the app really seems to be relaunched from the start) ? Is there a declaration to make in the Android Manifest to prevent this behavior ? Is that a known bug in some Android phones/versions ?

• Creating object/array to method in request based on __gettypes in PHP

  - by LochNess

  I'm having trouble with the array or object that should be passed based on the response from __gettypes. The __gettypes response: [0] => struct CDataWrapper { schema;any; } [1] => struct NewMember { MemberDetail MemberDetails;ArrayOfHobby Hobbies; } [2] => struct MemberDetail { string Name; string Age; string Sex; } [3] => struct ArrayOfHobby { Hobby Hobby; } [4] => struct Hobby { string Name; string HoursUsedOnHobbyWeekly;boolean Favourite; } ... etc. The methods are: [0] => ReceiveMemberResponse ReceiveMember(ReceiveMember $parameters) [1] => ReturnMemberResponse ReturnMember(ReturnMember $parameters) So far I have this PHP: $client = new SoapClient('http://domain.com?wsdl'); class MemberDetail { public $Name = ''; public $Age = ''; public $Sex = ''; } $mc = new MemberDetail(); $mc->Name= 'Bob'; $mc->Age= '14'; $mc->Sex= 'Male'; $myParam = array('ReceiveMember'=>$mc); $wcf = $client->ReceiveMember($myParam); $wcfResult = $wcf->ReturnMember; print_r($wcfResult) when i call the page it returns: Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error. I'm not really sure how to create the array or object to pass on as $myParam since im no expert with PHP either.

• @selector and return value

  - by user320926

  The idea it's very easy, i have an http download class, this class must support the http authentication but it's basically a background thread so i would like to avoid to prompt directly to the screen, i would like to use a delegate method to require from outside of the class, like a viewController. But i don't know if is possible or if i have to use a different syntax. This class use this delegate protocol: //Updater.h @protocol Updater <NSObject> -(NSDictionary *)authRequired; @optional -(void)statusUpdate:(NSString *)newStatus; -(void)downloadProgress:(int)percentage; @end @interface Updater : NSThread { ... } This is the call to the delegate method: //Updater.m // This check always fails :( if ([self.delegate respondsToSelector:@selector(authRequired:)]) { auth = [delegate authRequired]; } This is the implementation of the delegate method //rootViewController.m -(NSDictionary *)authRequired; { // TODO: some kind of popup or modal view NSMutableDictionary *ret=[[NSMutableDictionary alloc] init]; [ret setObject:@"utente" forKey:@"user"]; [ret setObject:@"password" forKey:@"pass"]; return ret; }

• Updating UI objects in windows forms

  - by P a u l

  Pre .net I was using MFC, ON_UPDATE_COMMAND_UI, and the CCmdUI class to update the state of my windows UI. From the older MFC/Win32 reference: Typically, menu items and toolbar buttons have more than one state. For example, a menu item is grayed (dimmed) if it is unavailable in the present context. Menu items can also be checked or unchecked. A toolbar button can also be disabled if unavailable, or it can be checked. Who updates the state of these items as program conditions change? Logically, if a menu item generates a command that is handled by, say, a document, it makes sense to have the document update the menu item. The document probably contains the information on which the update is based. If a command has multiple user-interface objects (perhaps a menu item and a toolbar button), both are routed to the same handler function. This encapsulates your user-interface update code for all of the equivalent user-interface objects in a single place. The framework provides a convenient interface for automatically updating user-interface objects. You can choose to do the updating in some other way, but the interface provided is efficient and easy to use. What is the guidance for .net Windows Forms? I am using an Application.Idle handler in the main form but am not sure this is the best way to do this. About the time I put all my UI updates in the Idle event handler my app started to show some performance problems, and I don't have the metrics to track this down yet. Not sure if it's related.

• MVC2 Json request not actually hitting the controller

  - by SlackerCoder

  I have a JSON request, but it seems that it is not hitting the controller. Here's the jQuery code: $("#ddlAdminLogsSelectLog").change(function() { globalLogSelection = $("#ddlAdminLogsSelectLog").val(); alert(globalLogSelection); $.getJSON("/Administrative/AdminLogsChangeLogSelection", { NewSelection: globalLogSelection }, function(data) { if (data.Message == "Success") { globalCurrentPage = 1; } else if (data.Message == "Error") { //Do Something } }); }); The alert is there to show me if it actually fired the change event, which it does. Heres the method in the controller: public ActionResult AdminLogsChangeLogSelection(String NewSelection) { String sMessage = String.Empty; StringBuilder sbDataReturn = new StringBuilder(); try { if (NewSelection.Equals("Application Log")) { int i = 0; } else if (NewSelection.Equals("Email Log")) { int l = 0; } } catch (Exception e) { //Do Something sMessage = "Error"; } return Json(new { Message = sMessage, DataReturn = sbDataReturn.ToString() }, JsonRequestBehavior.AllowGet); } I have a bunch of Json requests in my application, and it seems to only happen in this area. This is a separate area (I have 6 "areas" in the app, 5 of which work fine with JSON requests). This controller is named "AdministrativeController", if that matters. Does anything jump out anyone as being incorrect or why the request would not pass to the server side?

• Strongly typed dynamic Linq sorting

  - by David

  I'm trying to build some code for dynamically sorting a Linq IQueryable<. The obvious way is here, which sorts a list using a string for the field name http://dvanderboom.wordpress.com/2008/12/19/dynamically-composing-linq-orderby-clauses/ However I want one change - compile time checking of field names, and the ability to use refactoring/Find All References to support later maintenance. That means I want to define the fields as f=f.Name, instead of as strings. For my specific use I want to encapsulate some code that would decide which of a list of named "OrderBy" expressions should be used based on user input, without writing different code every time. Here is the gist of what I've written: var list = from m Movies select m; // Get our list var sorter = list.GetSorter(...); // Pass in some global user settings object sorter.AddSort("NAME", m=m.Name); sorter.AddSort("YEAR", m=m.Year).ThenBy(m=m.Year); list = sorter.GetSortedList(); ... public class Sorter ... public static Sorter GetSorter(this IQueryable source, ...) The GetSortedList function determines which of the named sorts to use, which results in a List object, where each FieldData contains the MethodInfo and Type values of the fields passed in AddSort: public SorterItem AddSort(Func field) { MethodInfo ... = field.Method; Type ... = TypeOf(TKey); // Create item, add item to diction, add fields to item's List // The item has the ThenBy method, which just adds another field to the List } I'm not sure if there is a way to store the entire field object in a way that would allow it be returned later (it would be impossible to cast, since it is a generic type) Is there a way I could adapt the sample code, or come up with entirely new code, in order to sort using strongly typed field names after they have been stored in some container and retrieved (losing any generic type casting)

• WPF or Silverlight Learning Resources for Business Applications

  - by Refracted Paladin

  I am the only developer at a non-profit organization(~200 employees) where we are a M$ shop and 90% of the things I develop are specific to our company and are internal only. I am given a lot of latitude on how I accomplish my goals so using new technologies is in my best interest. So far I have developed all winform & asp.net applications. I would now like to focus on XAML driven development(WPF & Silverlight) and would like your help. I am subscribed to numerous Silverlight blogs and I have went through a few good tutorials however, I would really appreciate a GOOD SOLID book in my hands going forward. I prefer learning books versus reference books and I REALLY would like one from a Business standpoint as well. Shameless, self-promoting is welcomed if you happen to be an author or reviewer for one that meets my criteria. I would, however, prefer that recomendations were based on first-hand experience(no, 'my friend as this awesome book he told me about', please). Though, I don't mind un-released books if say they are an updated version of an existing. disclaimer -- I know there are an insane amount of Book posts here(SO) but none I believe for my specific need. If there is and I missed it I apologize.

• Dictionaries with more than one key per value in Python

  - by nickname

  I am attempting to create a nice interface to access a data set where each value has several possible keys. For example, suppose that I have both a number and a name for each value in the data set. I want to be able to access each value using either the number OR the name. I have considered several possible implementations: Using two separate dictionaries, one for the data values organized by number, and one for the data values organized by name. Simply assigning two keys to the same value in a dictionary. Creating dictionaries mapping each name to the corresponding number, and vice versa Attempting to create a hash function that maps each name to a number, etc. (related to the above) Creating an object to encapsulate all three pieces of data, then using one key to map dictionary keys to the objects and simply searching the dictionary to map the other key to the object. None of these seem ideal. The first seems ugly and unmaintainable. The second also seems fragile. The third/fourth seem plausible, but seem to require either much manual specification or an overly complex implementation. Finally, the fifth loses constant-time performance for one of the lookups. In C/C++, I believe that I would use pointers to reference the same piece of data from different keys. I know that the problem is rather similar to a database lookup problem by a non-key column, however, I would like (if possible), to maintain the approximate O(1) performance of Python dictionaries. What is the most Pythonic way to achieve this data structure?

• Can I make an identity field span multiple tables in SQL Server?

  - by johnnycakes

  Can I have an "identity" (unique, non-repeating) column span multiple tables? For example, let's say I have two tables: Books and Authors. Authors AuthorID AuthorName Books BookID BookTitle The BookID column and the AuthorID column are identity columns. I want the identity part to span both columns. So, if there is an AuthorID with a value of 123, then there cannot be a BookID with a value of 123. And vice versa. I hope that makes sense. Is this possible? Thanks. Why do I want to do this? I am writing an APS.NET MVC app. I am creating a comment section. Authors can have comments. Books can have comments. I want to be able to pass an entity ID (a book ID or an author ID) to an action and have the action pull up all the corresponding comments. The action won't care if it's a book or an author or whatever. Sound reasonable?

• Fluently.Configure without explicitly entering types.

  - by user86431

  I'm trying to take my fluent mapping past the basic stuff that I've found here: http://wiki.fluentnhibernate.org/Fluent_configuration Where they explicitly add each type like this: ISessionFactory localFactory = Fluently.Configure() .Database( ObjectFactory.GetInstance<SybaseConfiguration>().GetSybaseDialect( "BLAH" ) ) .Mappings( m => { m.HbmMappings .AddFromAssemblyOf<StudTestEO>(); m.FluentMappings .AddFromAssemblyOf<StudTestEO>() .AddFromAssemblyOf<StudTestEOMap>(); } ) .BuildSessionFactory(); .BuildSessionFactory(); and trying to be able to take the assembly, get a list of it's types and pass that in instead kindf like this string FullEoAssemblyFName = webAccessHdl.GetMapPath(EoAssemblyFName); string FullMapAssemblyFName = webAccessHdl.GetMapPath(MapAssemblyFName); string FullConfigFileName = webAccessHdl.GetMapPath("~/" + NHibernateConfigFileName); if (!File.Exists(FullEoAssemblyFName)) throw new Exception("GetFactoryByConfigFile, EoAssemblyFName does not exist>" + FullEoAssemblyFName + "<"); if (!File.Exists(FullMapAssemblyFName)) throw new Exception("GetFactoryByConfigFile, MapAssemblyFName does not exist>" + FullMapAssemblyFName + "<"); if (!File.Exists(FullConfigFileName)) throw new Exception("GetFactoryByConfigFile, ConfigFile does not exist>" + FullConfigFileName + "<"); Configuration configuration = new Configuration(); Assembly EoAssembly = Assembly.LoadFrom(webAccessHdl.GetMapPath(EoAssemblyFName)); Assembly MapAssembly = Assembly.LoadFrom(webAccessHdl.GetMapPath(MapAssemblyFName)); Type[] EoType = EoAssembly.GetTypes(); Type[] MapType = MapAssembly.GetTypes(); ISessionFactory localFactory = fluent.Mappings( m => { // how do i add all the types from type array here? m.FluentMappings.Add(MapAssembly).AddFromAssembly(EoAssembly); } ) .BuildSessionFactory(); To get it to load the types genericly instead of explicitly.. has anyone done this, or see any good links to articles I should look at? Thanks, E-

• How can I use a compound condition in a join in Linq?

  - by Gary McGill

  Let's say I have a Customer table which has a PrimaryContactId field and a SecondaryContactId field. Both of these are foreign keys that reference the Contact table. For any given customer, either one or two contacts may be stored. In other words, PrimaryContactId can never be NULL, but SecondaryContactId can be NULL. If I drop my Customer and Contact tables onto the "Linq to SQL Classes" design surface, the class builder will spot the two FK relationships from the Customer table to the Contact table, and so the generated Customer class will have a Contact field and a Contact1 field (which I can rename to PrimaryContact and SecondaryContact to avoid confusion). Now suppose that I want to get details of all the contacts for a given set of customers. If there was always exactly one contact then I could write something like: from customer in customers join contact in contacts on customer.PrimaryContactId equals contact.id select ... ...which would be translated into something like: SELECT ... FROM Customer INNER JOIN Contact ON Customer.FirstSalesPersonId = Contact.id But, because I want to join on both the contact fields, I want the SQL to look something like: SELECT ... FROM Customer INNER JOIN Contact ON Customer.FirstSalesPersonId = Contact.id OR Customer.SecondSalesPersonId = Contact.id How can I write a Linq expression to do that?

• Convert SVG to PDF

  - by Adrian Smith

  How would one go about converting a SVG file to a PDF programatically? (I need to alter the SVG in certain respects before generating the PDF so simply pre-converting it using a tool won't be sufficient.) Ideally using Java but Perl or PHP would be fine too. Obviously I am basically considering Apache FOP and Batik with Java. However no matter how long I search I cannot find a simple introduction on how to do it. Things like SVGConverter have descriptions like "Defines the interface for classes that are able to convert part or all of a GraphicContext", but I don't really know what that means. I have this feeling there must be an API to do this quite simply, provided by FOP or Batik, but I'm just not able to find it at the moment (or perhaps it really doesn't exist.) In terms of the supported SVG features I need, the file has some paths which are filled with some linear gradients. Ideally if I could pass the SVG in as a DOM Document that would be ideal; then I would load my template SVG file, change it as specified by the user, and then generate the PDF.

• ASP.Net MVC - how can I easily serialize query results to a database?

  - by Mortanis

  I've been working on a little property search engine while I learn ASP.Net MVC. I've gotten the results from various property database tables and sorted them into a master generic property response. The search form is passed via Model Binding and works great. Now, I'd like to add pagination. I'm returning the chunk of properties for the current page with .Skip() and .Take(), and that's working great. I have a SearchResults model that has the paged result set and various other data like nextPage and prevPage. Except, I no longer have the original form of course to pass to /Results/2. Previously I'd have just hidden a copy of the form and done a POST each time, but it seems inelegant. I'd like to serialize the results to my MS SQL database and return a unique key for that results set - this also helps with a "Send this query to a friend!" link. Killing two birds with one stone. Is there an easy way to take an IQueryable result set that I have, serialize it, stick it into the DB, return a unique key and then reverse the process with said key? I'm using Linq to SQL currently on a MS SQL Express install, though in production it'll be on MS SQL 2008.

• Is this overly clever or unsafe?

  - by Liberalkid

  I was working on some code recently and decided to work on my operator overloading in c++, because I've never really implemented it before. So I overloaded the comparison operators for my matrix class using a compare function that returned 0 if LHS was less than RHS, 1 if LHS was greater than RHS and 2 if they were equal. Then I exploited the properties of logical not in c++ on integers, to get all of my compares in one line: inline bool Matrix::operator<(Matrix &RHS){ return ! (compare(*this,RHS)); } inline bool Matrix::operator>(Matrix &RHS){ return ! (compare((*this),RHS)-1); } inline bool Matrix::operator>=(Matrix &RHS){ return compare((*this),RHS); } inline bool Matrix::operator<=(Matrix &RHS){ return compare((*this),RHS)-1; } inline bool Matrix::operator!=(Matrix &RHS){ return compare((*this),RHS)-2; } inline bool Matrix::operator==(Matrix &RHS){ return !(compare((*this),RHS)-2); } Obviously I should be passing RHS as a const, I'm just probably not going to use this matrix class again and I didn't feel like writing another function that wasn't a reference to get the array index values solely for the comparator operation.

• UIDocumentInteractionController & ARC: [UIPopoverController dealloc] reached while popover is still visible

  - by muffel

  This issue or similar issues have been discussed here before, but I didn't find any working solution for me. I am using the following code to display a UIDocumentInteractionController on an ARC-enabled iOS 7 project: - (void) exportDoc{ // [...] docController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:path]]; docController.delegate = self; [docController presentOpenInMenuFromBarButtonItem:mainMenuButton animated:YES]; } First I didn't want to create a property that holds the controller reference, but as many people said that there are not alternatives to it. It is defined as @property (strong) UIDocumentInteractionController* docController; exportDoc is run in the main thread using NSOperationQueue. Whenever it is executed, I get the following error message: Terminating app due to uncaught exception 'NSGenericException', reason: '-[UIPopoverController dealloc] reached while popover is still visible.'

• Help dealing with data dependency between two registration forms

  - by franko75

  I have a tricky issue here with a registration of both a user and his/her pet. Both the user and the pet are treated as separate entities and both require separate registration forms. However, the user's pet has to be linked to the user via a foreign key in the database. The process is basically that when a new user joins the site, firstly they register their pet, then they register themselves. The reason for this order is to check their pet's eligibility for the site (there are some criteria to be met) first, instead of getting the user to sign up only to then find out their pet is ineligible. It is this ordering of the form submissions which is causing me a bit of a headache, as follows... The site is being developed with an MVC framework, and the User registration process is managed via a method in a User_form controller, while the pet registration process is managed via a method in the Pet_form controller. The pet registration form happens first, and the pet data can be saved without the owner_id at this stage, with the user id possibly being added (e.g by retrieving pet's id from session) following user registration. However, doing it this way could potentially result in redundant data, where pet records would be created in the database, but if the user doesn't actually register themselves too, then the pets will be ownerless records in the DB. Other option is to serialize the new pet's data at the pet registration stage, don't save it to the DB until the user fills out their registration form. Once the user is created, i can pass serialised data AND the owner_id to a method in the Pet Model which can update the DB. However, I also need to set the newly created $pet to $this-pet which I then access for a sequence of other related forms. Should I just set the session variable in the model method? Then in the Pet controller constructor, do a check for pet stored in session, if yes, assign to $this-pet... If this makes any sense to anybody and you have some advice, i'd be grateful to hear it!

• Unpacking varargin to individual variables

  - by Richie Cotton

  I'm writing a wrapper to a function that takes varargin as its inputs. I want to preserve the function signature in the wrapper, but nesting varargin causes all the variable to be lumped together. function inner(varargin) %#ok<VANUS> % An existing function disp(nargin) end function outer(varargin) % My wrapper inner(varargin); end outer('foo', 1:3, {}) % Uh-oh, this is 1 I need a way to unpack varargin in the outer function, so that I have a list of individual variables. There is a really nasty way to do this by constructing a string of the names of the variables to pass the inner, and calling eval. function outer2(varargin) %#ok<VANUS> % My wrapper, second attempt inputstr = ''; for i = 1:nargin inputstr = [inputstr 'varargin{' num2str(i) '}']; %#ok<AGROW> if i < nargin inputstr = [inputstr ', ']; %#ok<AGROW> end end eval(['inner(' inputstr ')']); end outer2('foo', 1:3, {}) % 3, as it should be Can anyone think of a less hideous way of doing things, please?

• How can I prevent double file uploading with Amazon S3?

  - by Tony

  I decided to use Amazon S3 for document storage for an app I am creating. One issue I run into is while I need to upload the files to S3, I need to create a document object in my app so my users can perform CRUD actions. One solution is to allow for a double upload. A user uploads a document to the server my Rails app lives on. I validate and create the object, then pass it on to S3. One issue with this is progress indicators become more complicated. Using most out-of-the-box plugins would show the client that file has finished uploading because it is on my server, but then there would be a decent delay when the file was going from my server to S3. This also introduces unnecessary bandwidth (at least it does not seem necessary) The other solution I am thinking about is to upload the file directly to S3 with one AJAX request, and when that is successful, make a second AJAX request to store the object in my database. One issue here is that I would have to validate the file after it is uploaded which means I have to run some clean up code in S3 if the validation fails. Both seem equally messy. Does anyone have something more elegant working that they would not mind sharing? I would imagine this is a common situation with "cloud storage" being quite popular today. Maybe I am looking at this wrong.

• C#; On casting to the SAME class that came from another assembly

  - by G. Stoynev

  For complete separation/decoupling, I've implemented a DAL in an assebly that is simply being copied over via post-build event to the website BIN folder. The website then on Application Start loads that assembly via System.Reflection.Assembly.LoadFile. Again, using reflection, I construct a couple of instances from classes in that assembly. I then store a reference to these instances in the session (HttpContext.Current.Items) Later, when I try to get the object stored in the session, I am not able to cast them to their own types (was trying interfaces initially, but for debugging tried to cast to THEIR OWN TYPES), getting this error: [A]DAL_QSYSCamper.NHibernateSessionBuilder cannot be cast to [B] DAL_QSYSCamper.NHibernateSessionBuilder. Type A originates from 'DAL_QSYSCamper, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location 'C:\Users\dull.anomal\AppData\Local\Temp\Temporary ASP.NET Files\root\ad6e8bff\70fa2384\assembly\dl3\aaf7a5b0\84f01b09_b10acb01\DAL_QSYSCamper.DLL'. Type B originates from 'DAL_QSYSCamper, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'LoadNeither' at location 'C:\Users\dull.anomal\Documents\Projects\QSYS\Deleteme\UI\MVCClient\bin\DAL_QSYSCa mper.DLL'. This is happening while debugging in VS - VS manages to stop into the source DAL project even though I've loaded from assembly and the project is not refferenced by the website project (they're both in the solution). I do understand the error, but I don't understand how and why the assembly is being used/loaded from two locations - I only load it once from the file and there's no referrence to the project. Should mention that I also use Windsor for DI. The object that tries to extract the object from the session is A) from a class from that DAL assembly; B) is injected into a website class by Windsor. I will work on adding some sample code to this question, but wanted to put it out in case it's obvious what I do wrong.

• SIlverlight Navigate: how does it work? How would you implement in f# w/o VS wizards and helpers?

  After a nights sleep the problem can be stated more accurately as I have a 100% f# / silverlight implementation and am looking to use the built in Navigation components. C# creates page.xaml and page.xaml.cs um - ok; but what is the relationship at a fundamental level? How would I go about doing this in f#? The applcuation is loaded in the default module, and I pull the XAML in and reference it from the application object. Do I need to create instances / references to the pages from within the application object? Or set up some other page management object with the proper name value pairs? When all the Help of VS is stripped away - what are we left with? original post (for those who may be reading replies) I have a 100% silverlight 3.0 / f# 2.0 application I am wrapping my brain around. I have the base application loading correctly - and now I want to add the naigation controls to it. My page is stored as an embedded resource - but the Frame.Navigate takes a URI. I know what I have is wrong but here it is: let nav : Frame = mainGrid ? mainFrame let url = "/page1.xaml" let uri = new System.Uri(url, System.UriKind.Relative) ; nav.Navigate uri Any thoughts?

• QT NOOB: Add action handler for multiple objects of same type.

  - by what

  I have a simple QT application with 10 radio buttons with names radio_1 through radio_10. It is a ui called Selector, and is part of a class called TimeSelector In my header file for this design, i have this: //! [1] class TimeSelector : public QWidget { Q_OBJECT public: TimeSelector(QWidget *parent = 0); private slots: //void on_inputSpinBox1_valueChanged(int value); //void on_inputSpinBox2_valueChanged(int value); private: Ui::Selector ui; }; //! [1] the commented out void_on_inputSpinBox1_valueChanged(int value) is from the tutorial for the simple calculator. I know i can do: void on_radio_1_valueChanged(int value); but I would need 10 functions. I want to be able to make one function that works for everything, and lets me pass in maybe a name of the radio button that called it, or a reference to the radio button so i can work with it and determine who it was. I am very new to QT but this seems like it should be very basic and doable, thanks.

• Task Queue stopped working

  - by pocoa

  I was playing with Goole App Engine Task Queue API to learn how to use it. But I couldn't make it trigger locally. My application is working like a charm when I upload to Google servers. But it doesn't trigger locally. All I see from the admin is the list of the tasks. But when their ETA comes, they just pass it. It's like they runs but they fails and waiting for the retries. But I can't see these events on command line. When I try to click "Run" on admin panel, it runs successfuly and I can see these requests from the command line. I'm using App Engine SDK 1.3.4 on Linux with google-app-engine-django. I'm trying to find the problem from 3 hours now and I couldn't find it. It's also very hard to debug GAE applications. Because debug messages do not appear on console screen. Thanks.

• How do I get require_login()-like functionality using the new PHP Client Library for Facebook?

  - by cc

  Howdy. I've been tasked with making a Facebook game, but I'm new to Facebook development, so I'm just getting started. Apologies in advance if this is a no-brainer to people. I'm having trouble following all the examples I see on sites, and I keep running into missing pages in the Facebook documentation when I am trying to read up. I think it's because there's a new version of the PHP Client Library for Facebook, and everything I'm finding is referring to the old client. For instance, I see this code in a lot of examples: require 'facebook.php'; $facebook = new Facebook( array( 'appId' => '(id)', 'secret' => '(secret)' ) ); $facebook_account = $facebook->require_login(); ...but there's no "require_login()" in the client library provided in the facebook.php file. From what I can tell, it looks like Facebook has very recently rolled out some new system for development, but I don't see any sample code anywhere to deal with it. The new library comes with an "example.php" file, but it appears to be only for adding "Log in with Facebook" functionality to other sites (what I'm assuming is what they mean by "Facebook Connect" sites), not for just running apps in a Canvas page on Facebook itself. Specifically, what I need to do is let users visit an application page within Facebook, have it bring up the dialog box allowing them to authorize the app, have it show up in their "games" page, and then have it pass me the relevant info about the user so I can start creating the game. But I can't seem to find any tutorials or examples that show how to do this using the new library. Seems like this should be pretty straightforward, but I'm running into roadblocks. Or am I missing something about the PHP client library? Should require_login() be working for me, and there's something broken with my implementation, such as having the wrong client library or something? I downloaded from GitHub yesterday, so I'm pretty sure I have the most recent version of the code I have, but perhaps I'm downloading the wrong "facebook.php" file...?

• Serializability of enum-like class

  - by callisto

  I need to access an enum through a webservice. As a webservice allocates 0 based integers to an enumeration (ignoring preset values in enum definition), I built the following: public class StatusType { public StatusVal Pending { get { return new StatusVal( 1, "Pending"); } } public StatusVal Authorised { get { return new StatusVal(2, "Authorised"); } } public StatusVal Rejected { get { return new StatusVal(3, "Rejected"); } } public StatusVal Sent { get { return new StatusVal(4, "Sent"); } } public StatusVal InActive { get { return new StatusVal(5, "InActive"); } } public List<StatusVal> StatusList() { List<StatusVal> returnVal = new List<StatusVal>(); StatusType sv = new StatusType(); returnVal.Add(sv.Pending); returnVal.Add(sv.Authorised); returnVal.Add(sv.Rejected); returnVal.Add(sv.Sent); returnVal.Add(sv.InActive); return returnVal; } } public class StatusVal { public StatusVal(int a, string b) { this.ID = a; this.Name = b; } public int ID { get; set; } public string Name { get; set; } } I then get the list of StatusVal with the following webmethod: [WebMethod] public List<ATBusiness.StatusVal> GetStatus() { ATBusiness.StatusType a = new ATBusiness.StatusType(); return a.StatusList(); } I cannot however use this webmethod as referring it, I get the error: StatusVal cannot be serialized because it does not have a parameterless constructor. I don't quite understand: should I pass params into the StatusValue type defined as the WebMethod's return Type? I need this to return a list of StatusVals as per the StatusList() method.
