• Is there any Android XML documentation?

  - by Eddified

  Is there any sort of xml reference? I found this which turned out to be invaluable for me http://groups.google.com/group/android-developers/msg/d334017d72909c79 but I can't figure out how I was supposed to know how to do that, had I not found that post. I know that the api reference has xml attributes listed for many of the classes... but what about xml tags? Where is it documented that I could build a shape using , , tags? I'd really like to know where I can find such documentation.

• Simplest way to extend doctrine for MVC Models

  - by RobertPitt

  Im developing my own framework that uses namespaces. Doctrine is already integrated into my auto loading system and im now at the stage where ill be creating the model system for my application Usually i would create a simple model like so: namespace Application\Models; class Users extends \Framework\Models\Database{} which would inherit all the default database model methods, But with Doctrine im still learning how it all works, as its not just a simple DBAL. I need to understand whats the part of doctrine my classes would extend where i can do the following: namespace Application\Models; class Users Extends Doctrine\Something\Table { public $__table_name = "users"; } And thus within the controller i would be able to do the following: public function Display($uid) { $User = $this->Model->Users->findOne(array("id" => (int)$id)); } Anyone help me get my head around this ?

• Confused about "override" vs. "new" in C#

  - by iTayb

  I'm having the following classes: class Base { public virtual void Print() { Console.WriteLine("Base"); } } class Der1 : Base { public new virtual void Print() { Console.WriteLine("Der1"); } } class Der2 : Der1 { public override void Print() { Console.WriteLine("Der2"); } } This is my main method: Base b = new Der2(); Der1 d1 = new Der2(); Der2 d2 = new Der2(); b.Print(); d1.Print(); d2.Print(); The output is Base, Der2, Der2. As far as I know, Override won't let previous method to run, even if the pointer is pointing to them. So the first line should output Der2 as well. However Base came out. How is it possible? How the override didn't work there?

• Managing Data Prefetching and Dependencies with .NET Typed Datasets

  - by Derek Morrison

  I'm using .NET typed datasets on a project, and I often get into situations where I prefetch data from several tables into a dataset and then pass that dataset to several methods for processing. It seems cleaner to let each method decide exactly which data it needs and then load the data itself. However, several of the methods work with the same data, and I want the performance benefit of loading data in the beginning only once. My problem is that I don't know of a good way or pattern to use for managing dependencies (I want to be sure I load all the data that I'm going to need for each class/method that will use the dataset). Currently, I just end up looking through the code for the various classes that will use the dataset to make sure I'm loading everything appropriately. What are good approaches or patterns to use in this situation? Am I doing something fundamentally wrong? Although I'm using typed datasets, this seems like it would be a common situation where prefetching data is used. Thanks!

• Include a Class in another model / class / lib

  - by jaycode

  I need to use function "image_path" in my lib class. I tried this (and couple of other variations): class CustomHelpers::Base include ActionView::Helpers::AssetTagHelper def self.image_url(source) abs_path = image_path(source) unless abs_path =~ /^http/ abs_path = "#{request.protocol}#{request.host_with_port}#{abs_path}" end abs_path end end But it didn't work. Am I doing it right? Another question is, how do I find the right class to include? For example if I look at this module: http://api.rubyonrails.org/classes/ActionView/Helpers/AssetTagHelper.html is there a rule of thumb how to include that module in a model / library / class / anything else ?

• Is it weird or strange to make multiple WCF Calls to build a ViewModel before presenting it?

  - by Nate Bross

  Am I doing something wrong if I need code like this in a Controller? Should I be doing something differently? public ActionResult Details(int id) { var svc = new ServiceClient(); var model = new MyViewModel(); model.ObjectA = svc.GetObjectA(id); model.ObjectB = svc.GetObjectB(id); model.ObjectC = svc.GetObjectC(id); return View(model); } The reason I ask, is because I've got Linq-To-Sql on the back end and a WCF Service which exposes functionality through a set of DTOs which are NOT the Linq-To-Sql generated classes and thus do not have the parent/child properties; but in the detail view, I would like to see some of the parent/child data.

• Problem in serializing

  - by Harun

  Hello Guyz, Presently I need to serialize one of my object which contains more my own classes object. But the problem is I dont want to save it in a file and then retrieve it into memory stream. Is there any way to directly serialize my object into stream. I used BinaryFormatter for seializing. First I used a MemoryStream directly to take serialize output but it is giving error at time of deserialization. But later when I serialize it with a file then close it and again reopen it , it works perfectly. But I want to take it direct into stream because in my program I need to do it frequently to pass it into network client. And using file repeatedly might slow down my software. Hope I clear my problem. Any Sugetion ?

• How can I persist a large Perl object for re-use between runs?

  - by Alnitak

  I've got a large XML file, which takes over 40 seconds to parse with XML::Simple. I'd like to be able to cache the resulting parsed object so that on the next run I can just retrieve the parsed object and not reparse the whole file. I've looked at using Data::Dumper but the documentation is a bit lacking on how to store and retrieve its output from disk files. Other classes I've looked at (e.g. Cache::Cache appear designed for storage of many small objects, not a single large one. Can anyone recommend a module designed for this? EDIT. The XML file is ftp://ftp.rfc-editor.org/in-notes/rfc-index.xml On my Mac Pro benchmark figures for reading the entire file with XML::Simple vs Storable are: s/iter test1 test2 test1 47.8 -- -100% test2 0.148 32185% --

• Class interaction

  - by user1264391

  Ok so I'm doing a simulation about a "Mall" I have many classes in the same "level" which corresponds to each person's personality. For example I have the class: clown, thief, assassin, materialist, etc. in the same level And a father class called Clients. In the Client class I have some methods for eating,walking, etc. and each specific class has a specific method, the thief steals, assassin kills, etc. I was wondering how could I put every "client" in a list and still cast every specific method?

• Guice ThrowingProvider problem

  - by KARASZI István

  According to the ThrowingProvider documentation of Guice I have the following interface: public interface IConfigurableProvider<T> extends ThrowingProvider<T, ConfigException> {} I have multiple classes that implements this interface, let assume I have the following: public class SomethingProvider extends ConfiguredProvider implements IConfigurableProvider<Something> {} Of course this class implements the necessary method: public Something get() throws ConfigException { /* ... */ } In my module, I have the following code in MyModule.java ThrowingProviderBinder.create(binder()) .bind(IConfigurableProvider.class, Something.class) .to(SomethingProvider.class); But when I start my application the following error produced: 6) No implementation for com.package.Something was bound. while locating com.package.Something for parameter 5 at com.package.OtherClass.<init>(OtherClass.java:78) at com.package.MyModule.configure(MyModule.java:106) I don't really know where should I start looking for the bug.

• Problem accessing base member in derived constructor

  - by LeopardSkinPillBoxHat

  Given the following classes: class Foo { struct BarBC { protected: BarBC(uint32_t aKey) : mKey(aKey) mOtherKey(0) public: const uint32_t mKey; const uint32_t mOtherKey; }; struct Bar : public BarBC { Bar(uint32_t aKey, uint32_t aOtherKey) : BarBC(aKey), mOtherKey(aOtherKey) // Compile error here }; }; I am getting a compilation error at the point indicated: error: class `Foo::Bar' does not have any field named `mOtherKey'. Can anyone explain this? I suspect it's a syntactical problem due to my Bar class being defined within the Foo class, but can't seem to find a way around it. This is simple public inheritance, so mOtherKey should be accessible from the Bar constructor. Right? Or is it something to do with the fact that mOtherKey is const and I have already initialised it to 0 in the BarBC constructor?

• Reporting. MS Word templates population required

  - by Andrew Florko

  Application we developed fills MS Word templates with data from Database. Customers require to have ability edit Word templates via MS Word (change style, font, layout e.t.c) with no additional software to be installed and no training. AFAIK, Sql Reporting Services and Crystal Reports can't populate MS Word templates produced in MS Word. So we implemented our custom solution that maps .net classes onto xml-saved MS Word documents. It looks like we declare class MyTemplate { // maps to [age] field declared in ms document straight in the text int Age { get; set; } // maps to table by attributes applied to property (omitted) List<Person> Persons { get; set; } } We also implemented images insertion. Are there any free libraries for this task or may be you use your own MS-word templators in your projects?

• Call AppDelegate Method from Class

  - by golfromeo

  Basically, I need to call a method in my AppDelegate from one of my view controller classes. Currently, I'm doing the following: myAppDelegate *appDelegate = (myAppDelegate *)[[UIApplication sharedApplication] delegate]; [appDelegate doMethod]; And including the myAppDelegate.h at the top of the .m file of the class: #import "myAppDelegate.h" When I run it, everything works... But I get the following warning: warning 'myAppDelegate' may not respond to '-doMethod' Is there another way that I should reference the app delegate? Thanks for any help in advance.

• How do I create a point system in a Rails app that assigns points to users and non-authenticated-use

  - by codyvbrown

  I'm building a question and answer application on top of twitter and I'm hitting some snags because I'm inevitably dealing with two classes of users: authenticated and non-authenticated. The site enable users to give points to other users, who may or may not be authenticated, and I want to create a site-wide point system where the application stores and displays this information on their profile. I want to save this point data to the user because that would be faster and more efficient but non-authenticated users aren't in our system, we only have the twitter handle. So instead we display the points in our system like this: @points = point.all( :select => "tag, count(*) AS count", # Return tag and count :group => 'tag', # Group by the tag :order => "2 desc", :conditions => {:twitter_handle => params[:username]}) Is there a better way to do this? Is there a better way to associate data with non-authenticated users?

• Sql query builder c# for windows mobile

  - by pdiddy

  I'm building a windows mobile app. And using SqlCe. I'm looking for a good sql query builder. So instead of writing "SELECT COLUMNS FROM TABLE WHERE etc... Is there a good free library that can build this sort of query? EDIT: You know when you write your code with ADO.net something like this SqlCeCommand command = new SqlCeCommand(Connection); command.CommandText = "SELECT * FROM Orders WHERE customerId = @customerId"; Well i'm looking for some library that could build that SELECT statement using classes instead of writing it through string. So something like: SqlCeCommand command = new SqlCeCommand(Connection); SqlQueryBuilder query = new SqlQueryBuilder(); query.Table = "Orders"; query.AddWhere("customerId", myValue) command.CommandText = query.toString(); Something like that .... so a class that will build the query..

• Check for state change in objects using serialization?

  - by sev7n

  I have a form that is bind to an object, and when the user trying to leave the form, I want to warn them if anything on the form has been changed, and prompt them to save. My question is, is there any way to achieve this without implementing IComparar for all my classes in the binded object? I was thinking if there is a way I can serialize my object when loading the form, and do a simple comparison against the change object that also get serialized. Something like a string comparison. Hope that make sense, Thanks

  we tried to give our tables(users,messages) like this in two different abstract classes but it is not working. This is included in a file childconnect1.php ,is there any relation between the file name(childconnect1.php) and the class(Application_Model_childconnect1). class Application_Model_childconnect1 extends Zend_Db_Table_Abstract { protected $_name = 'users'; public function loginvalidation($username,$pwd) { $row = $this->fetchRow('UserName = \'' . $username .

• Changing A Different Class Display on Hover with Jquery

  - by John K

  Ok, here's what I'm trying to do. I have a DIV box with a child element set with DISPLAY: NONE;. I'm trying to use Jquery so that when the mouse enters the parent DIV box, the child element is made visible, and then hides when the mouse leaves the parent DV. There will be multiple divs on the page with these classes. For some reason it's not working. Any ideas? Here's my code: HTML: <div class="parent"> <span class="handle" style="display: none;">My Handle</span> <p>Child Text</p> </div> Javascript: $(document).ready(function () { $('.parent').mouseenter(function(){ $(this).next('.handle').show(); }); $('.parent').mouseleave(function(){ $(this).next('.handle').hide(); }); })

• Summary count for Python logging

  - by Craig McQueen

  At the end of my Python program, I'd like to be able to get a summary of the number of items logged through the standard logging module. I'd specifically like to be able to get a count for each specified name (and possibly its children). E.g. if I have: input_logger = getLogger('input') input_logger.debug("got input1") input_logger.debug("got input2") input_logger.debug("got input3") network_input_logger = getLogger('input.network') network_input_logger.debug("got network input1") network_input_logger.debug("got network input2") getLogger('output') output_logger.debug("sent output1") Then at the end I'd like to get a summary such as: input: 5 input.network: 2 output: 1 Perhaps by calling a getcount() method for a logger or a handler. What would be a good way to achieve this? I imagine it would involve a sub-class of one of the logging classes, but I'm not sure which one would be best.

• Is there a way to reference a certain class/interface/... by enclosing it with its namespace rather than a using directive "using namespace_name" ?!

  - by Ahmed

  Is there a way to reference a certain class/interface/... by enclosing it with its namespace rather than a using directive "using namespace_name" ?! As, I'm working on a website, which uses SAP .NET connector. I already added a reference for connector ddl, and while referencing its namespace "using namespace_name", or set class namespace to another one rather than connector namespace, I got error regarding connector classes with that error message "The type or namespace couldn't be found, are you missing a using directive or an assembly reference?". But while changing namespace name to connector namespace, everything is going well?! // Set namespace to be IDestinationConfiguration interface namespace. namespace SAP.Middleware.Connector { public class ConnectorConfiguration : IDestinationConfiguration { } } So, connector types forced me to set namespace of class to their namespace! Is this possible? If so, how?

• Where is BuildConfig.DEBUG?

  - by Ollie C

  My project doesn't seem to be aware of this new constant that's apparently auto-generated in Android Tools r17 builds: "Added a feature that allows you to run some code only in debug mode. Builds now generate a class called BuildConfig containing a DEBUG constant that is automatically set according to your build type. You can check the (BuildConfig.DEBUG) constant in your code to run debug-only functions such as outputting debug logs." I've confirmed that this class is not being auto-generated anywhere in my project by the new tools. I deleted all project outputs (including all gen folders) and rebuilt, and only R.java classes are being generated. Why are the tools not generating the BuildConfig class? It may be relevant that I'm using IntelliJ.

• Navigation properties not set when using ADO.NET Mocking Context Generator

  - by olenak

  I am using ADO.NET Mocking Context Generator plugin for my Entity Framework model. I have not started on using mocks yet, just trying to fix generated entity and context classes to make application run as before without exceptions. I've already fixed T4 template to support SaveChanges method. Now I've got another problem: when I try to access any navigation property it is set to null. All the primitive fields inherited from DB table are set and correct. So what I am doing is the following using (var context = MyContext()) { var order = context.Orders.Where(p => p.Id == 7); var product = order.Products; } in this case product is set to null. But that was not a case while using default code generator, it used to return real product object. Thanks ahead for any suggestions!
