  • An EventBus framework for Android

    - by Benju
    Can anybody recommend a good framework for handling events in Android? These would be business logic events like UserUpdatedEvent. I am looking for something similar to the EventBus provided by GWT-EVENT but for a JVM that supports weak-references.

  • C# immutable object usage best practices? Should I be using them as much as possible?

    - by Daniel
    Say I have a simple object such as class Something { public int SomeInt { get; set; } } I have read that using immutable objects are faster and a better means of using business objects? If this is so, should i strive to make all my objects as such: class ImmutableSomething { public int SomeInt { get { return m_someInt; } } private int m_someInt = 0; public void ChangeSomeInt(int newValue) { m_someInt = newvalue; } } What do you reckon?

  • What is your custom exception hierrarchy?

    - by bonefisher
    My question is: how would you create exception hierarchy in your application? Designing the architecture of an application, from my perspective, we could have three types of exceptions: the built-in (e.g.: InvalidOperationException) custom internal system faults (DB transaction failed on commit, DbTransactionFailedException) custom business exceptions (BusinessRuleViolationException) Class hierarchy: Exception MyAppInternalException DbTransactionFailedException MyServerTimeoutException ... MyAppBusinessRuleViolationException UsernameAlreadyExistsException ... where only MyAppInternalException & MyAppBusinessRuleViolationException would be catched.

  • WCF doesn't find client configuration

    - by ultraman69
    Hi ! I have a WCF service on server B. Then on the machine A is the client, which is a Windows service. In a separate dll stands all the business logic for this service. So my proxy for the WCF is on that side. I have 2 app.config (client side only) : 1 for the service and another one in the dll. So I tried (for test purpose) puting the servicemodel config section in both. Both still, it doesn't work, it says that it can't find the endpoint with that name and for that contract... What I'm trying to do here is modify the configuration programatically. Here' the code in the business layer dll : Dim ep As New EndpointAddress(New Uri(ConfigurationManager.AppSettings(nomServeurCible)), _ EndpointIdentity.CreateDnsIdentity(ConfigurationManager.AppSettings("Identity_" & nomServeurCible))) serviceCible = New ServiceProxy.ExecOperClient("wsHttp", ep) And here is a sample of the config file : <add key="TEST1" value="http://TEST1:8000/MySpacePerso/ExecOperService"/> <add key="TEST1_CertificateSerialNumber" value="10 hj 6y 7b 00 01 32 12 01 21"/> <add key="Identity_TEST1" value="TEST1"/> <system.serviceModel> <client> <endpoint address="http://SERV_NAME:8000/CSSTQDA/ExecOperService" binding="wsHttpBinding" behaviorConfiguration="myClientBehavior" bindingConfiguration="MybindingCon" contract="ExecOper.Service.IExecOper" name="wsHttp"> <identity> <dns value="SERV_CERT_NAME"/> </identity> </endpoint> </client> <bindings> <wsHttpBinding> <binding name="MybindingCon"> <security mode="Message"> <message clientCredentialType="UserName" /> </security> </binding> </wsHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="ServiceTraitementBehavior"> <serviceMetadata httpGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="True" /> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="myClientBehavior"> <clientCredentials> <serviceCertificate> <authentication certificateValidationMode="ChainTrust" revocationMode="NoCheck"/> </serviceCertificate> </clientCredentials> </behavior> </endpointBehaviors> </behaviors>

  • Better languages than SQL for stored procedures

    - by Ken Paul
    I'm getting increasingly frustrated with the limitations and verbosity required to actually commit some business logic to stored procedures, using languages such as Transact-SQL or PL/SQL. I would love to convert some current databases to Oracle and take advantage of its support for Java stored procedures, but that option is not available at the moment. What alternatives would you recommend in the way of databases that support stored procedures in other languages?

  • Validating method arguments with Data Annotation attributes

    - by schemer
    The "Silverlight Business Application" template bundled with VS2010 / Silverlight 4 uses DataAnnotations on method arguments in its domain service class, which are invoked automagically: public CreateUserStatus CreateUser(RegistrationData user, [Required(ErrorMessageResourceName = "ValidationErrorRequiredField", ErrorMessageResourceType = typeof(ValidationErrorResources))] [RegularExpression("^.*[^a-zA-Z0-9].*$", ErrorMessageResourceName = "ValidationErrorBadPasswordStrength", ErrorMessageResourceType = typeof(ValidationErrorResources))] [StringLength(50, MinimumLength = 7, ErrorMessageResourceName = "ValidationErrorBadPasswordLength", ErrorMessageResourceType = typeof(ValidationErrorResources))] string password) { /* do something */ } If I need to implement this in my POCO class methods, how do I get the framework to invoke the validations OR how do I invoke the validation on all the arguments imperatively (using Validator or otherwise?).

  • How to handle input and parameter validation between layers?

    - by developr
    If I have a 3 layer web forms application that takes user input, I know I can validate that input using validation controls in the presentation layer. Should I also validate in the business and data layers as well to protect against SQL injection and also issues? What validations should go in each layer? Another example would be passing a ID to return a record. Should the data layer ensure that the id is valid or should that happen in BLL / UI?

  • How to choose programming language for projects?

    - by bdhar
    This is a question I constantly encounter when I attend any technical forums / discussions / interviews. There is a similar article but it focuses on business merits as well. What I am looking for is a guide (not a checklist like this one which is abstract and not so accurate) which helps an architect to choose the programming language to implement a requirement. Is there a book or article available for the same purpose?

  • Easy to use web-based reporting tool

    - by SuperFurryToad
    I'm looking for recommendations for an easy to use reporting/business intelligence tool that can interface with an sql server or access database. It can be web-based or a desktop tool. Ideally it would be freeware or low cost, and easy to use for users who are not that technically savvy (below the level of someone who can generate reports and complicated queries in Access). Any tools I've seen so far (such as Crystal Reports) are either too expensive or too complicated to use for non-power users.

  • N-Tiered application design tool

    - by Ben V
    I'm beginning the design of a medium-sized web application. I usually like to design from the top down, i.e., start at the highest level and design my way down. I am planning to have the following layers: Presentation (PHP/Ajax) Business Logic Data Access Database Now I'd like to start sketching out the major objects in each layer and the interaction between layers. Is there a tool more specific to this purpose than just using a graphics/diagramming tool like Visio?

  • Specification Pattern vs Spec in BDD

    - by cadmium
    I'm trying to explore Behavior Driven Design and Domain Driven Design. I'm getting that written specifications drive the tests in BDD, but also that business logic can be encapsulated using the specification pattern for re-use in domain objects and repositories, etc. Are these basically the same concept just used in different ways, used in conjunction together, or am I completely confusing the concepts? Please shed some light, if possible.

  • Excel VBA Application.OnTime. I think its a bad idea to use this... thoughts either way?

    - by FinancialRadDeveloper
    I have a number of users I support that are asking for things to happen automatically ( well more automagically but that's another point!). One want events to happen every 120 secs ( see my other question ) and also another wants 1 thing to happen say at 5pm each business day. This has to be on the Excel sheet so therefore VBA as addins etc will be a no no, as it needs to be self contained. I have a big dislike of using Application.OnTime I think its dangerous and unreliable, what does everyone else think?
