• IOC are at the class level, but what about database conflicts?

  - by mrblah

  With IOC I understand you can substitue implementations out by merely editing a configuration file etc. BUT, what happens when the classes are married to particular database tables and sprocs, you can't just swap out an implementation since the classes/entities are tied to particular tables and stored procedures. Am I right here?

• How to create an formatted localized string?

  - by mystify

  I have an localized string which needs to take a few variables. However, in localization it is important that the order of the variables can change from language to language. So this is not a good idea: NSString *text = NSLocalizedString(@"My birthday is at %@ %@ in %@", nil); In some languages some words come before others, while in others it's reverse. I lack of an good example for the moment. How would I provide NAMED variables in an formatted string? Is there any way to do it without some heavy self-made string replacements? Even some numbered variables like {%@1}, {%@2}, and so on would be sufficient... is there a solution?

• naming a method - using set() when *not* setting a property?

  - by user151841

  Is setX() method name appropriate for only for setting class property X? For instance, I have a class where the output is a string of an html table. Before you can you can call getTable, you have to call setTable(), which just looks at a other properties and decides how to construct the table. It doesn't actually directly set any class property -- only causes the property to be set. When it's called, the class will construct strHtmlTable, but you can't specify it. So, calling it setTable breaks the convention of get and set being interfaces for class properties. Is there another naming convention for this kind of method? Edit: in this particular class, there are at least two ( and in total 8 optional ) other methods that must be called before the class knows everything it needs to to construct the table. I chose to have the data set as separate methods rather than clutter up the __construct() with 8 optional parameters which I'll never remember the order of.

• if all my views are passed a strongly typed viewdata, if they have a baseviewdata class, can I set a

  - by Blankman

  I want all my views to inherit from a baseview data so I can set some shared properties that all my views will need. Can I set some properties in OnExecuting so I don't have to do it for all Actions? I want to then display the string value of the property in all my view pages. If yes, how can I do this? I need to hook into the base view data somehow? so i'll have: public MyViewData : ViewData { } And I need one for generics also?

• What's the correct way to instantiate an IRepository class from the Controller?

  - by GenericTypeTea

  I have the following project layout: MVC UI |...CustomerController (ICustomerRepository - how do I instantiate this?) Data Model |...ICustomerRepository DAL (Separate Data access layer, references Data Model to get the IxRepositories) |...CustomerRepository (inherits ICustomerRepository) What's the correct way to say ICustomerRepository repository = new CustomerRepository(); when the Controller has no visibility to the DAL project? Or am I doing this completely wrong?

• C++ header files and variable scope

  - by MrDatabase

  I want to organize my c++ variables and functions in the following way: function prototypes in a header file "stuff.h", function implementation in "stuff.cpp", then say #include "stuff.h" in main.cpp (so I can call functions implemented in stuff.cpp). So far so good. Now I want to declare some variables in stuff.cpp that have global scope (so I can modify the variables in functions implemented in stuff.cpp and main.cpp). This doesn't seem to work. How can I do this?

• VB.NET Abstract Property

  - by ElPresidente

  I have an abstract "GridBase" class with two types of derived classes "DetailGrid" and "HeaderGrid". Respectively, one is comprised of "DetailRow" objects and the other "HeaderRow" objects. Both of those inherit from a "RowBase" abstract class. What I am trying to do is the following: Public MustInherit Class GridBase Private pRows As List(Of RowBase) Public ReadOnly Property Rows As List(Of RowBase) Get Return pRows End Get End Property End Class Public Class DetailGrid Inherits GridBase End Class In this scenario, I want DetailGrid.Rows to return a list of DetailRow. I want HeaderRow.Rows to return a list of HeaderRow. Am I on the right track with this or should the Rows property not be included in the GridBase class?

• Pass the current state of a function into another function in C/C++

  - by sand

  Is there a way to pass the current state of a function into another function in C/C++? I mean all the parameters and local variables by current state. For example: void funcA (int a, int b) { char c; int d, e; // Do something with the variables. // ... funcB(); // Do something more. } void funcB() { // funcB() should be able to access variables a,b,c,d & e // and any change in these variables reflect into funcA(). } The code is in bad shape if there is a need for funcB() kind of functions. But can it be achieved? This can help if someone is starting to re-factor a long method with multiple parameters.

• Property hiding and reflection (C#)

  - by tehMick

  Declaring a property in a derived class that matches the name of a property in the base class "hides" it (unless it overrides it with the override keyword). Both the base and derived class properties will be returned by Type.GetProperties() if their types don't match. However, if their types do match, shockingly only the derived class's property is returned. For instance: class A { protected double p; public int P { get { return (int)p; } set { p = value; } } } class B : A { public new int P { get { return (int)p; } set { p = value; } } } class C : B { public new float P { get { return (float)p; } set { p = value; } } } Calling typeof(C).GetProperties() will only return B.P and C.P. Is it possible to call GetProperties() in a way that returns all three? There is almost certainly a way to do it by traversing the inheritance hierarchy, but is there a cleaner solution?

• Is there a .NET class that represents operator types?

  I would like to do the following: *OperatorType* o = *OperatorType*.GreaterThan; int i = 50; int increment = -1; int l = 0; for(i; i o l; i = i + increment) { //code } this concept can be kludged in javascript using an eval()... but this idea is to have a loop that can go forward or backward based on values set at runtime. is this possible? Thanks

• Are there any open source C# libraries for binding the properties from one class to another?

  I don't remember which blog I was reading, because it seemed academic at the time, but there was a library being discussed where you could take a two concrete classes and bind the properties together if the names matched. Think ASP.NET MVC model binding.

• Is it acceptable to design my GLSurfaceView as a main control class?

  - by Omega

  I'm trying to structure a game I'm making in Android so that I have a sound, flexible design. Right now I'm looking at where I can tie my games rules engine and graphics engine together and what should be in between them. At a glance, I've been eying my implementation of GLSurfaceView, where various screen events are captured. My rationale would be to create an instance of my game engine and graphics engine here and receive events and state changes to trigger updates of either where applicable. Further to this, in the future, the GLSurfaceView implementation could also store stubs for players during a network game and implementations of computer opponents and dispatch them appropriately. Does this seem like a sensible design? Are there any kinds of improvements I can make? Thanks for any input!
