code-reuse

I am trying to learn programming through Python, so I apologize in advance if this is an absurdly simple question. I am attempting to simplify my convoluted directory structure and utilize some of Python's code-reuse features, I have encountered what is for me an inexplicable ImportError error. For the past several hours I've been reading about Python's import , module , and package features ( here , here , here , and here among others), yet I remain unable to solve this (seemingly) simple error. Here is the problem. I have one directory ( dir ), within which resides one sub-directory ( subdir

Is there a way to implement the idea of a data domains (at a property level) inside of a class that is used as a model in a view in ASP.Net MVC 4? Consider this code: public class LoginProfileModel { [DisplayName("Login ID")] [Required(ErrorMessage = "Login ID is required.")] public string LogonID { get; set; } [DisplayName("Password")] [Required(ErrorMessage = "Password cannot be blank.")] [StringLength(20, MinimumLength = 3)] [DataType(DataType.Password)] public string Password { get; set; } } Here is a LoginProfileModel in for ASP.Net MVC 4. It uses a variety of metadata/data annotations so

If your company or project places an emphasis on (or at least appreciates) the development of code and components that can be reused and shared across projects, what are the "social engineering" things you've needed to do to facilitate the re-use the code? In my experience, code or components that are simply stated as being "reusable" won't be reused unless that code has someone to champion or evangelize it. Otherwise, people simply won't know about it. How do you make sure shared components or reusable code work in your organization? A couple of thoughts come to mind: Make them very well

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 EE web application and the desktop app is a limited functionality version of the web app. Up until now all business logic and data access code was coded separately for each application. The data stores were different for each application (Web is SQL Server and

I am trying to set up my ExtJS 4 project so I have three top level applications, for example, /foo/app.js /bar/app.js /baz/app.js Each 'top level' application is a separate ExtJS application, each with their own loaders. There are some cases were I will have general components that I want to share between all three applications, so I have /components top level directory. If I have a component name say ComponentA, /components/componenta.js How would I go about getting ComponentA into all three applications, so it could referenced or extended by the individual application? You can add this same

I know ASP.NET MVC 3 doesn't support area reuse, which would be very handy for, say, user admin areas of web applications, but how about partial views? Say I have Pager "control" as a Razor (or WebFormViewEngine , it doesn't matter) partial view which I can easily reuse inside my MVC application. Is it possible to reuse it in multiple MVC applications other than by creating a partial view in the new application and copy-pasting the code? Darin Dimitrov There is nothing buit-in the framework that allows you to do this. You may take a look at MVCContrib portable areas which allows you to embed

From reading many articles, such as How do I include a JavaScript file in another JavaScript file? - it is apparently not possible to include one script into another. So here's my question - I'm concerned about JS bloat. or having too much unused code loading with pages that don't use/need it. However, occasionally, I'll need the same functions on multiple pages, but not all pages. If we look at making logical sections of an online application into objects, such as 'customers' or 'items' - we may have a bunch of code that is specific to each of these 'objects'. As an example, I could have a

Let's say, I have a function: var rand = function(n) { return Math.floor(Math.random() * n); } Can I use this function in both Content Script and Background Script without copypaste? Thank you. Yes. You could have an external JS file which is loaded as part of the background and the content script (like any normal JS file). Just add it to the background and content script file arrays in the manifest and it will be loaded for you. For example if our shared function reside in sharedFunctions.js , the content script using them is in mainContentScript.js and the background code in mainBackground
