Hi all, I am the .Net specialist in a consultancy with many difference flavors of developers using many different languages and frameworks. Because everyone is pretty much trying to push their own agendas with our different clients in terms of what technology to propose, I'm constantly finding myself in the classic arguments with them a...
[I'm not asking about the architecture of SO, but it would be helpful to the question.] On SO, when a user clicks on his/her name and clicks on "responses" they see other users responses to comment threads, questions, and answers in which they have participated. I've had the sneaking suspicion that I've missed certain responses out ther...
I have a very general design question, but I'll frame it in concrete terms with an example. Suppose you're working on embedded software for a digital printer. The machine has 4 print heads (for each of the C, M, Y, K colors). Each print head performs the same task: fetching toner and putting it on the page. At runtime, we could organ...
We have introduced BizTalk into our organization as a Service Bus, it is linking a new Web GUI to numerous existing back end systems. We have wrapped our existing systems as Services (WCF) and connected them to the BUS. We are also replacing some of the legacy system GUI's with our new web GUI (ensuring we replicate existing functionali...
When creating a website my pattern often is the following: Controllers (application services) Services (domain services, infrastructure services) Repositories Controllers talk to domain services or infrastructure services, and domain services may talk to repositories, infrastructure services will wrap things like smtp etc. Currently...
I am currently tasked with creating a documented, consistent Architecture guide for software development. We have a lot of smart people doing the right things, but just not consistently and repeatably. We are using Microsoft’s Application Architecture Guide 2.0 as a starting point. Hence coming up with an Application Architecture is fai...
I'm trying to modify a C# WinForms application that uses multiple forms. At startup, a login window will be shown. If the user logs in with a correct user name and password combo a form with three different tabs will be shown as a sort of administrators view. If no password or user name is supplied, a much simplified GUI will be shown. I...
Looking for advice, links, design patterns, etc. on the best way to design an application where entities and related screens could be extended with additional attributes/related lookups via metadata/without recompile, ideally by end users. I'm thinking something very similiar to how Dynamics CRM 4.0 works with extension tables/dynamic p...
I'm trying to come up with a checklist or set of questions/criteria to assess and evaluate proposed or emergent architectures (perform architectural reviews). What are the most important questions you ask when trying to plan, assess or review an architecture? I know this is a large topic so I'd like to constrain it to a single end-to...
We are starting a new JEE project and am looking for suggestions regarding design patterns to expose the backend interfaces. It would be preferable if the backend logic can run seamlessly on Tomcat, other JEE5 containers. We are currently veering towards JEE5, EJB3, JPA and the preferred deployment platform is JBoss 5 AS. We would expe...
Every enemy type in my game is a different class, and the instances are stored in a C array. In the main game loop update() is run for each enemy/item instance, and draw() is run. Some of the update() commands require knowledge of where the main player is. What would be the best route to get that information to the instance? I don't thin...

For easy of databinding and to be able to re use data validation built-in my business objects, I choosed to reference the business objects library from the xBap client instead of generat...
Hi there. I am starting a new Winforms application, and I've always used traditional ADO.NET methods in my DAL (...yes, hardcoding!) I have used Linq on many ocassions previously, but more for adhoc queries, so I have some experience with it and I loved how easy it was to write querying code. What I would like to perhaps do is replace ...
I have the need from an asp.net web site to send out many SMS messages at once, and also poll a POP3 account for an incoming mail, and then SMS that out to many recipients, one at a time. The way I am thinking of doing this is a windows service that would connect to my sql back-end to see if there are SMS messages to be sent out, like e...

Note the namespace assigned for that class : namespace SResocentroAnalytics.Controls.WinForms.Chart { ///...
I'm working on a project that I want to have be as flexible and scalable as possible from the beginning. A problem I'm concerned about is one best described by Joshua Schacter in Founders at Work, who noted it as one detail he wish he would've planned for ahead of time. Scaling past one machine, one database, is very challenging, eve...

Here's the architecture of my app: I have a data access layer in a seperate assembly, with a class containing methods such as List_XYZ, Insert_XYZ, Update_XYZ etc. All methods return or use objects from an object model I've created, which also resides in the data access layer assembly. Inside my mvc app, I've created views, controller...
