One of my friend (he is a .NET/C++ developer, as I am) asked me: Dependency injection: do we all need to know that? Why? Could you please tell: Your opinion: do we really need to know that pattern and how to implement it? Good reference (link) that could explain "why?" Thank you a lot. P.S. I am understanding that I am asking ...
I made a .NET Windows form that allows users to view a particular document and sign it. I want to make it re-usable for future applications. The challenges are: The text to be signed requires parameters. Before the user signs it, the text is just a query - not saved anywhere When the user signs it, the text he/she signed must be sto...
As a software developer for 6 years, I've had a range of experiences with different teams, from negative to positive. One of the best experiences I had was in a certain project team at a financial organization. There were a number of factors that made the project successful, but I think the team structure was a key aspect of it. To su...
Here's the situation. We have a 3rd party middleware (using SQLServer as a back-end) which we communicate with using an HTTP service link and XMLRPC-like messaging. The service always returns a dataset as results of any commands that returns something. There is a way to pass an embedded SQL statement to the service. So, we do not have...
I would like to be able to read Rails source code, but I think I can't really do it, because I don't know were to start and how different parts of the code are connected. For example, it's obvious what ActiveModel does and I can read the code, but I don't understand how a Rails app generally gets loaded and when exactly ActiveModel comes...
I have a layer of business-level objects and a layer of contract-level objects in a WCF service application. The business layer objects I'm referring to are just entity or POCO objects that I'm using to hold data. The contract-level objects I'm referring to are the objects that make up the WSDL my clients see (also POCOs). When I return...
Hi All, Scenario: I'm working on a web services project. It supports SOAP and REST. The SOAP request and response are handled by XmlObjects. The REST architectures uses plain POJO's for request and Response. I have a common controller to handle the request from SOAP and REST. This controller understands a common object (Request Object)....
code sample taken from MSDN public class Test { public static void Main() { MyBaseClass myBase = new MyBaseClass(); MyDerivedClass myDerived = new MyDerivedClass(); object o = myDerived; MyBaseClass b = myDerived; Console.WriteLine("mybase: Type is {0}", myBase.GetType()); Console.WriteLine("myDerived: Type is {0}", myDeriv...
My company's web architecture has essentially got an extra layer due to client security requirements, which complicates the process of developing applications a bit. I'd like to get some input and suggestions on the best way to do so. First, an overview: presentation layer - this is mostly PHP, with some flex applications as well. We ...
Possible Duplicate: What PHP-specific questions would you ask in a job interview? I need to interview some experienced php web developers, some of them with zend certification. Just asking them some php/mysql questions is not enough so I need to test at least the following abilities: abstract thinking self initiative applica...
Hi Everyone, I've created a generic 'SocketServer' class in java which takes the following arguments: String address, int port, Class socketProtocol, String encryptionType, int backlogSize Basically, I want other developers to be able to instance this class in their projects and set some simple options for encryption, backlog, address,...
I want to create a small helpdesk ticket control system at work, that would allow users to enter a help request ticket; these tickets would then be assigned to a technician to work on, and the technician would mark it as "FINISHED" after the job is done. The requesting user would then be able to confirm and "CLOSE" the ticket, so that a ...
I need to come up with a solution for complicated file transfer. I can do this, but I want to know if anybody knows of an open source solution that already does 90% of what I want to do. The requirements are very odd. Don't try to understand them, they are a hellish mixture of politics, territory, and bureaucracy. I control two serve...
I would like to validate some objects. The validation has two parts: validation whether the user has right to access the object (the specific rights are already calculated and stored in boolean values, there are maximum 4 roles) checking if the object is in a certain state (from a set of states) I have a lot of rules (actually around...

If I use MS Access in the back-end of a client-server type software and the database file is sent from client to server, will it create any problems in further database handling, transfer speed, or performance compared to SQL Server? ...
Hello, In the application I'm building, the user may perform something in one view (backed by a view model) that should trigger an action in one or more other view models. Each of these other vms needs the ability to veto (a.k.a. cancel) the action performed in the first v/vm pair. Example: User clicks on an account in a DataGrid co...
For a basic CMS that does not require dynamic functionality like comments, why not write static .html files to disk? Then a high-performance, static file, web server like nginx could be used to serve the files. This would theoretically deliver the highest performance web site possible. EDIT: "Basic CMS", in my mind, is something a compa...
This is a pretty straightforward architectural question, however it's been niggling at me for ages. The whole point of using a list, for me anyway, is that it's O(1) insert/remove. The only way to have an O(1) removal is to have an iterator for erase(). The only way to get an iterator is to keep hold of it from the initial insert() or t...
