reusability

问题 Although my question might seem abstract I hope it's not. Suppose I develop an application, an ASP.NET MVC site and later I am tasked to build an Winforms client for this application how much and how can I reuse from the existing application? I defined the models, I defined controllers and views. They all work well. Now the boss comes asking for a Winforms client and I am hoping I can reuse the models and the controllers (provided I put them in different assemblies) and not reuse just the

问题 I am trying to setup a repository of reusable code. I was thinking about having each reusable code module have a certain “Maturity Level” rating. The rating would be defined as the level at which a reusable code lies within a certain set of requirements. The highest maturity level will be the highest degree of standard across a predefined set of requirements. For example: Level; Requirements; Description Level 0; Code is legal to use; Is the code legal to use in commercial industry/across

问题 So I'm optimizing a C# program which uses byte arrays very very frequently, I wrote a kind of recycle pool thing to reuse arrays which had to be collected by GC. Like that: public class ArrayPool<T> { private readonly ConcurrentDictionary<int, ConcurrentBag<T[]>> _pool; public ArrayPool() { _pool = new ConcurrentDictionary<int, ConcurrentBag<T[]>>(); } public ArrayPool(int capacity) { _pool = new ConcurrentDictionary<int, ConcurrentBag<T[]>>(4, capacity); for (var i = 1; i <= capacity; i++) {

问题 I have this accordion function : $('.accordion a').click(function () { if($(this).is('.accordionClose')) { $('.accordionOpen').toggleClass('accordionOpen').toggleClass('accordionClose').next().slideToggle().toggleClass('openContent'); $(this).toggleClass('accordionOpen').toggleClass('accordionClose'); $(this).next().slideToggle().toggleClass('openContent'); } else { $(this).toggleClass('accordionOpen').toggleClass('accordionClose'); $(this).next().slideToggle().toggleClass('openContent'); } }

问题 I've been grappling with this problem throughout the life of my project. I have many lists in my project and most of them have headers. I have been making a separate layout file and adding it to the list using addHeaderView(). The problem is that when the data (ArrayList, in my case) is empty, the header doesn't appear. After hours of searching for a way to reuse the header layout as an empty view, I gave up and decided to replicate the layout in code and assign it as an empty view using

问题 I have a custom UITableViewCell which contains several UIButtons. Each button's frame position is relative to the cell width. I set autoresizingMask=UIViewAutoresizingFlexibleWidth so it will adjust the cell width and the button positions properly when the application starts with the device either in landscape or portrait mode. The issue is when the device is rotated from one mode to the other, the buttons do not adjust positions because the UITableViewCell is reusable. In other words, the

问题 I've got three different UITableViews, each in it's own view, accessed via tabs. All three tables would ideally share the same custom UITableViewCell class and .xib file. I started with one table, setting the class of the .xib to my custom class and the File's Owner of the .xib to the table's parent UIViewController, which works great. All of the custom view-related code is in the cell's class (background images based on a property set by the controller, custom cell height based on the number

问题 ViewHolder pattern improves ListView scrolling framerate, as seen in following example: https://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List14.html Is it possible to keep this pattern while using different kind of Views for different rows? In other words, is it possible to do something like: public View getView(int position, View view, ViewGroup parent) { // calculate viewID here if (view == null || *view is not null but was created from different

问题 This is in NetBeans 6.5, Java 6. I have the following hierarchy in the NetBeans GUI Designer: JFrame JTabbedPane JPanel X <...> JPanel JButton JPanel Y <...> JButton Question: JPanel Y is identical to JPanel X, so I'd like to simply reuse JPanel X in both places, but how do I do this inside the GUI Builder? Attempts: I tried copy-pasting JPanel X, but it creates a full "deep" copy (JPanel X1, etc), duplicating everything in JPanel X. Some googling indicated it might be possible to add it to
