Building ASP.NET Single Page Applications in HTML 5 with Upshot
By:
Brian Noyes
Last updated: Wednesday, August 31, 2022
Published in: CODE Magazine: 2012 - September/October
A Single Page Application (SPA) is a different way of building HTML 5 applications from traditional Web page development. Instead of spreading the functionality of your Web applications across a collection of separate Web pages with hyperlinks between them, you instead define a single root page that the user lands on and never leaves as long as they are working with your application. You define client-side logic that switches out the data and chunks of content within that page to allow the user to navigate from logical screen to logical screen without ever leaving the page. This means that the user never sees a full page refresh while using your application. They see portions of the screen change based on their interaction, and those changes can be done in a more fluid way with transitions to enhance the user experience. You can also support using the application while offline by storing data client-side, based on some of the newer APIs of HTML 5. Taking this approach makes an SPA feel very much like a desktop application to the end user.

Last updated: Wednesday, August 31, 2022
Published in: CODE Magazine: 2011 - March/April
Visual Studio LightSwitch applications consist of three tiers: presentation, logic and data. This article discusses the logic tier and its save pipeline. The save pipeline is where developers write business logic that runs as changes are processed on the logic tier and saved to the data storage tier. The save pipeline is automatically generated with every LightSwitch application. Understanding the processing done in the save pipeline is not required to successfully build and deploy applications with LightSwitch, but adding save pipeline business logic provides additional flexibility and control when data is saved.

When developing with Windows Live services, you open your application to a whole new world of software integration. In this fascinating realm of mash-up mania, developers can find tools for adding maps, searches, video, chats, and even social networking services directly into their applications and ultimately right into their users’ browsers. The benefit of adding services like Virtual Earth and Silverlight Streaming are obvious-creating dazzling content and facilitating rich user experiences. Yet services like these are still limited to specific contexts within your program. They are perfectly wonderful for beefing up the user experience in Web sites, but wouldn’t it be great if the folks at Microsoft provided a service that helps you administer user accounts and customize services around your Web site? Well indeed they have, and its name is Windows Live Admin Center (admincenter.live.com).

IT professionals agree that input is a big source of trouble. Input ultimately determines how applications work and wrong or malicious input may cause serious damage. It is extremely important that developers have this fact firmly in mind and consequently apply adequate countermeasures. Starting from the perspective that all input is evil is a good approach. Reasoning in terms of a whitelist instead of a blacklist is another excellent strategy. Working with strongly typed data is the third pillar of secure applications. This article discusses the role of input data and related attacks in the context of ASP.NET applications.

SQLCLR Security and Designing for Reuse

Last updated: Wednesday, February 20, 2019
Published in: CODE Magazine: 2007 - May/June
An important principal of software design is that of “least privilege.”Basically, in any given layer of a program, you should only grant minimal access such that the code has rights to only exactly the resources it needs to get its job done-and nothing more. Most SQL Server developers understand this concept: one of the main reasons to use stored procedures is to encapsulate permission to data behind controlled and auditable interfaces, thereby not giving the caller direct access.

Building a PreserveProperty Control in ASP.NET 2.0
By:
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2007 - March/April
ASP.NET provides a couple of page-level state persistence mechanisms in ViewState and the new ControlState.While both mechanisms work, they both have some limitations in that they are not deterministic for the application developer-ViewState can be turned off and can be very bulky, and ControlState can only be set from within a control implementation. In this article I’ll show another, more flexible state mechanism using a PreservePropertyControl that allows automatic persistence and restoration of field values automatically without requiring ViewState.

Do you ever feel like you’re beating your head against a wall? I know I do; quite often, in fact. It seems like developers spend half of their time bending technology to their purposes when the technology doesn’t really quite fit. Well, I’m actually thinking of one problem in particular right now, namely that of validation. Can you think of a more boring topic? There are few, but I think you can agree that it is an extremely important one in business software.

The Baker’s Dozen: 13 Steps for Building a Lookup Page Using ASP.NET 2.0, SQL 2005, and C# 2.0
By:
Last updated: Wednesday, August 31, 2022
Published in: CODE Magazine: 2007 - March/April
Lookup and navigation screens initially seem like no-brainers, when compared to other parts of an application-yet by the time a developer has met all the user requirements and requests, he/she has expended much more time than expected. This issue of The Baker’s Dozen will build a lookup Web page using ASP.NET 2.0, SQL Server 2005, and C# 2.0. The lookup and results page will contain optional lookup criteria and custom paging of the result set. The solution will utilize new language features in SQL 2005 for providing ranking numbers to correlate with custom paging, and new capabilities in .NET generics to pump the results of a stored procedure into a custom collection. Just like Mr. Mayagi taught Daniel the martial arts by doing exercises, the example in this article will demonstrate some common design patterns, such as factory creation patterns, using .NET generics. The article also subtly presents a general methodology for building database Web pages.

Detect Web Form Field Changes in ASP.NET
By:
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2006 - September/October
In ASP.NET, the value change related event will be triggered at server side per server control when the value of such a server control (form field) is changed upon postback. In most cases, a group of form fields are correlated with each other and typically correspond to member data in a business object. Thus developers need to check if such a group of form fields has changed as a whole. Unfortunately, the .NET Framework (1.x, 2.0) doesn’t offer an effective solution. This article will present an elegant technique to solve this problem and it can even go further so that you can know which field has changed.

Remote Object Models In .NET
By:
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2003 - January/February
Modern applications are no longer isolated, stand-alone applications, limited to a single process or machine. Distributed applications allow you to put components in close proximity to the resources they use, allow multiple users to access the application, enable scalability and throughput, and increase overall availability and fault isolation. Component-oriented programming is especially geared towards distribution because it is all about breaking the application into a set of interacting components, which you can then distribute to different locations. .NET has a vast infrastructure supporting distributed applications and remote calls. This article focuses on just a single aspect of .NET remoting: the different object activation models available to a distributed application.
