I have used inheritance before quite a lot and I'm comfortable with in that area. I have a very brief design that I'm going to implement: public interface IMyExceptionLogger { public void LogException(); // ...

I have an application that will make a use of DBExceptionLogger. The application references only IExceptionLogger. How do I create an instance of DBExceptionLogger wit...
I love Asserts and code readability but not code duplication, and in several places I use a Debug.Assert which checks for the same condition like so: Debug.Assert(kosherBaconList.SelectedIndex != -1, "An error message along the lines - you should not ever be able to click on edit button without selecting a kosher bacon first."); This ...
I am working on a web application which requires the user to login before they see or do anything. No part of this app should be accessible without being logged in.

I have a layout in Google Web Toolkit using UIBinder involving a TabLayoutPanel. This layout has the superset of all tabs that will be used by my app (think of it as an admin view).

Is there any way I could save my block of code in Visual Studio 2010 and reuse it in my future web applications without having to "Add existing files"? Is there a feature in VS2010 that lets you globally store these blocks of code? Thanks! ...
I am trying to measure how much of the code produced in our organisation is actually reusable and I'd like to set some guidelines. I'd like to have some reference to outer world: How much code is typically reused in a single application ? More specifically - if we consider all the code of a complete end-user product (and eventually excl...
Hi, Currently, I have a more or less organized set of projects I work or worked on. Some are refactored, documented and unit-tested, others are not. When I want to reuse a code I've written before, I spend a few minutes searching for the project where I've written this code, than copy-paste this code to a new one, refactoring, document...
Android resources and their automatically generated references simplify the development of one app a great deal. But they also complicate the reuse of Android activities in multiple projects, and in general of any component that uses resources. Library projects are a limited alternative. A project can depend on many library projects, bu...
I am developing on a system that is a bit difficult to work with. It is 99% undocumented, does not follow best practices and is fairly difficult to understand (globals galore, methods spanning 50 lines, eval abuse, etc.). Unfortunately, I am fairly new to the code base and I need to add functionality. I am sure there is code in there th...

I have to produce another table of funds and while I'm doing that, I'd like to create FundsTable.ascx partial view that all Views that need to display a fund table can use. // Inherits="System.Web.Mvc.ViewPage<CompanyViewModel> // this is a company <%f...
I have a Java web application that has a 'disconnected' Java Swing desktop app. Using the desktop app users connect to the internet and download data they need from a server. They can disconnect and use the application offline. When they reconnect to the internet they can sync their data back to the server. The server itself is a Java...
Need help here, I'm a coder who has always felt the weight of a tremendously strong force pushing him to reinvent the wheel. It was so strong that I was nearly trying to reinvent jQuery lately [Note] and this really made me think. I read also these well written articles, but they don't give any practical suggestions to follow in order...
