  • [Java2D] Is this bad practice? Multiple Graphics2D Objects

    - by m00st
    I've created a JPanel canvas that holds all graphics; namely JLabel. To get animated sprites to work you have to over ride the paintComponent of the extended JLabel class. I've successfully implemented animated sprites this way. Is it bad practice to have a Graphics2D canvas and then have multiple 'images' in their own Graphics2D?

  • COM-Objects containing maps / content error(0)

    - by Florian Berzsenyi
    I'm writing a small wrapper to get familiar with some important topics in C++ (WinAPI, COM, STL,OOP). For now, my class shall be able to create a (child) window. Mainly, this window is connected to a global message loop that distribute messages to a local loop of the right instance (global is static, local is virtual). Obviously, there are surely better ways to do that but I'm using std::maps to store HWND and their instance pointer in pairs (the Global loop looks for the pointer with the HWND-parameter, gets itself the pointer from the map and calls then the local loop). Now, it appears that the map does not accept any values because of a unknown reason. It seems to allocate enough space but something went wrong anyway [ (error) 0 is displayed instead of the entries in visual C++). I've looked that up in google as well and found out that maps cause some trouble when used in classes AND DLLs. May this be the reason and is there any solution?? Protected scope of class: static std::map<HWND,MAP_BASE_OBJECT*> m_LoopBuf Implementation in .cpp-file: std::map<HWND,MAP_BASE_OBJECT*> HWindow::m_LoopBuf;

  • Deleting objects through foreign key relationship with T-SQL query

    - by LaserBeak
    Looking for a way to write the following LinQ to entities query as a T-SQL statement. repository.ProductShells.Where(x => x.ShellMembers.Any(sm => sm.ProductID == pid)).ToList().ForEach(x => repository.ProductShells.Remove(x)); The below is obviously not correct but I need it to delete respective ProductShell object where any ShellMember contains a ProductID equal to the passed in variable pid. I would presume this would involve a join statement to get the relevant ShellMembers. repository.Database.ExecuteSqlCommand("FROM Shellmembers WHERE ProductID={0} DELETE FK_ProductShell", pid); I have cascade delete enabled for the FK_ShellMembers_ProductShells foreign key, so when I delete the ProductShell it will delete all the ShellMembers that are associated with it. I am going to pass this statement to System.Data.Entity Database.ExecuteSqlCommand method.

  • Stop objects from wrapping in Android

    - by jay
    How do I prevent a TextView, or any visual object, from wrapping to the screen and instead being chopped off the sides? Is there some XML attribute or code to do this or is it impossible to have anything overflow from the screen? For example, you have this: But you really want this: Any ideas?

  • Mock Assertions on objects inside Parallel ForEach's???

    - by jacko
    Any idea how we can assert a mock object was called when it is being accessed inside Parallel.ForEach via a closure? I assume that because each invocation is on a different thread that Rhino Mocks loses track of the object? Pseudocode: var someStub = MockRepository.GenerateStub() Parallel.Foreach(collectionOfInts, anInt => someStub.DoSomething(anInt)) someStub.AssertWasCalled(s => s.DoSomething, Repeat.Five.Times) This test will return an expectation violation, expecting the stub to be called 5 times but being actually called 0 times. Any ideas how we can tell the lambdas to keep track of the thread-local stub object?

  • Modeling objects with multiple table relationships in Zend Framework

    - by andybaird
    I'm toying with Zend Framework and trying to use the "QuickStart" guide against a website I'm making just to see how the process would work. Forgive me if this answer is obvious, hopefully someone experienced can shed some light on this. I have three database tables: CREATE TABLE `users` ( `id` int(11) NOT NULL auto_increment, `email` varchar(255) NOT NULL, `username` varchar(255) NOT NULL default '', `first` varchar(128) NOT NULL default '', `last` varchar(128) NOT NULL default '', `gender` enum('M','F') default NULL, `birthyear` year(4) default NULL, `postal` varchar(16) default NULL, `auth_method` enum('Default','OpenID','Facebook','Disabled') NOT NULL default 'Default', PRIMARY KEY (`id`), UNIQUE KEY `email` (`email`), UNIQUE KEY `username` (`username`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 CREATE TABLE `user_password` ( `user_id` int(11) NOT NULL, `password` varchar(16) NOT NULL default '', PRIMARY KEY (`user_id`), UNIQUE KEY `user_id` (`user_id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 CREATE TABLE `user_metadata` ( `user_id` int(11) NOT NULL default '0', `signup_date` datetime default NULL, `signup_ip` varchar(15) default NULL, `last_login_date` datetime default NULL, `last_login_ip` varchar(15) default NULL, PRIMARY KEY (`user_id`), UNIQUE KEY `user_id` (`user_id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 I want to create a User model that uses all three tables in certain situations. E.g., the metadata table is accessed if/when the meta data is needed. The user_password table is accessed only if the 'Default' auth_method is set. I'll likely be adding a profile table later on that I would like to be able to access from the user model. What is the best way to do this with ZF and why?

  • Accessing jQuery objects in the module pattern

    - by Stewart
    Hello, Really getting in to javascript and looking around at some patterns. One I have come accross is the module pattern. Its seems like a nice way to think of chucks of functionality so I went ahead and tried to implement it with jQuery. I ran in to a snag though. Consider the following code <!DOCTYPE html> <html> <head> <meta http-equiv="Content-type" content="text/html; charset=utf-8"> <title>index</title> <script type="text/javascript" charset="utf-8" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script> <script type="text/javascript" charset="utf-8"> $(document).ready(function(){ var TestClass2 = (function(){ var someDiv; return { thisTest: function () { someDiv = document.createElement("div"); $(someDiv).append("#index"); $(someDiv).html("hello"); $(someDiv).addClass("test_class"); } } })(); TestClass2.thisTest(); }); </script> </head> <body id="index" onload=""> <div id="name"> this is content </div> </body> </html> The above code alerts the html content of the div and then adds a class. These both use jQuery methods. The problem is that the .html() method works fine however i can not add the class. No errors result and the class does not get added. What is happening here? Why is the class not getting added to the div?

  • Injecting correct object graph using StructureMap in Queue of different Objects

    - by davy
    I have a queuing service that has to inject a different dependency graph depending on the type of object in the queue. I'm using Structure Map. So, if the object in the queue is TypeA the concrete classes for TypeA are used and if it's TypeB, the concrete classes for TypeB are used. I'd like to avoid code in the queue like: if (typeA) { // setup TypeA graph } else if (typeB) { // setup TypeB graph } Within the graph, I also have a generic classes such as an IReader(ISomething, ISpomethingElse) where IReader is generic but needs to inject the correct ISomething and ISomethingElse for the type. ISomething will also have dependencies and so on. Currently I create a TypeA or TypeB object and inject a generic Processor class using StructureMap into it and then pass a factory manually inject a TypeA or TypeB factory into a method like: Processor.Process(new TypeAFactory) // perhaps I should have an abstract factory... However, because the factory then creates the generic IReader mentioned above, I end up manually injecting all the TypeA or TypeB classes fro there on. I hope enough of this makes sense. I am new to StructureMap and was hoping somebody could point me in the right direction here for a flexible and elegant solution. Thanks

  • What happens with unarchived objects?

    - by Dane Man
    After I've unarchived an object with NSKeyedUnarchiver, I am able to use it like usual, but I am unable to re-archive it. When I try, it crashes. [NSKeyedArchiver archiveRootObject:unarchivedObject toFile:fileName]; I tried looking in the developer resources in apple but I haven't seen a thorough explination of proper usage of NSKeyedArchiver. Please Help.

  • Dottrace Dead vs. Garbage

    - by Moshe
    After reading the dottrace documentation I realized that: Dead objects are objects deleted before the end point of the snapshot. Garbage objects are objects allocated after the starting point and deleted before the end point - in other words, "Garbage objects" is a subset of "Dead objects". But after doing some profiling sessions, I could see that sometimes the number of "Garbage objects" is by far greater than the number of "Dead objects" of the same class (for example System.String). How should I interpret this phenomenon?

  • Add custom Model Binders for derived objects and their base

    - by mare
    My class diagram: BaseContentClass Page inherits BaseContentClass Tab inherits BaseContentClass ... If I do this ModelBinders.Binders.Add(typeof(BaseContentObject), new BaseContentObjectCommonPropertiesBinder()); then when in controller action parameter of type Tab appears, custom model binder is not fired. It gets fired if I do this: ModelBinders.Binders.Add(typeof(Tab), new BaseContentObjectCommonPropertiesBinder()); But I don't want to go writing "n" number of Add statements in my global.asax.cs to associate all the derived classes with my custom model binder, do I? I don't know if I have any other option.

  • Setting property of objects in datacontext

    - by ryudice
    Hi, all my entities have a common property which specifies the company they belong to, I would like to set this property in a method in my datacontext but I do not want to use the partial methods for each of the entity types that the datacontext provides, is there a method that receives any entity that is inserted throught the datacontext so that I can hook to it or override it and set the property using reflection? thanks.

  • Objects do not retain the frame that I give then when using CGAffineTransforms with Core Animation

    - by user170030
    Hi, I'm making a game where when a card is touched, it grows so that it is focused, and when you 'let go', it goes back to its original size and place. This seems pretty standard, however, when I add cards and move the hand around to accommodate different numbers of cards, touching the card makes it go to its original place, and not to the new place. This has been stumping me for a while now Any hints would be much appreciated. Thanks !

  • Mapping child objects in fluent nhibernate to a read-only view

    - by grenade
    Given that I am implementing a read-only UI, how do I create a ClassMap for Shop: public class Shop { public int Id { get; set; } public City City { get; set; } } public class City { public string Name { get; set; } public string CountryCode { get; set; } } The DB interface for Shops is a View containing 3 columns (ShopId, CityName, CountryCode). I was hoping to do something like this: public sealed class ShopMap : ClassMap<Shop> { public ShopMap() { Table("Shop"); Id(x => x.Id, "ShopId"); Map(x => x.City.Name, "CityName"); Map(x => x.City.CountryCode, "CountryCode"); } } Will fluent auto-instantiate Shop.City?

  • How to create tests for poco objects

    - by Simon G
    Hi, I'm new to mocking/testing and wanting to know what level should you go to when testing. For example in my code I have the following object: public class RuleViolation { public string ErrorMessage { get; private set; } public string PropertyName { get; private set; } public RuleViolation( string errorMessage ) { ErrorMessage = errorMessage; } public RuleViolation( string errorMessage, string propertyName ) { ErrorMessage = errorMessage; PropertyName = propertyName; } } This is a relatively simple object. So my question is: Does it need a unit test? If it does what do I test and how? Thanks

  • Hos to group the complex list objects by using Linq

    - by Daoming Yang
    I want to select and group the products, and rank them by the number of times they occur. For example, I have an OrderList each of order object has a OrderProductVariantList(OrderLineList), and each of OrderProductVariant object has ProductVariant, and then the ProductVariant object will have a Product object which contains product information. A friend helped me with the following code. It could be compiled, but it did not return any value/result. I used the watch window for the query and it gave me "The name 'query' does not exist in the current context". Can anyone help me? Many thanks. var query = orderList.SelectMany( o => o.OrderLineList ) // results in IEnumerable<OrderProductVariant> .Select( opv => opv.ProductVariant ) .Select( pv => p.Product ) .GroupBy( p => p ) .Select( g => new { Product = g.Key, Count = g.Count() });
