The Baker’s Dozen: A 13-Step Crash Course for Using LINQ
By:
Kevin Goff
Last updated: Wednesday, August 31, 2022
Published in: CODE Magazine: 2007 - July/August
How many software tasks DON’T involve reading through data? Answer: very few. Developers work all the time with database data, XML data, DataSets, collections, lists, and arrays-all with different syntax and functionality for each one. Developers who write T-SQL code often covet set-based language statements when they work against other types of data. Additionally, developers who have coded against strongly-typed custom collections wish they could write SQL database queries with IntelliSense. Language Integrated Query (LINQ), a set of extensions to the .NET Framework for the next version of Visual Studio codename “Orcas”, brings the promise of integrated and uniform query capabilities to increase developer productivity when working with different types of data. While LINQ is a large topic worthy of books, this edition of The Baker’s Dozen will provide a crash course to learn what’s under the LINQ hood.

Chapter 1: Introducing .NET
By:
David Chappell
Last updated: Tuesday, February 19, 2019
Published in: Book Excerpts
From the book Understanding .NET by David Chappell, published by Addison Wesley Microsoft's .NET is revolutionizing Windows-based software development. Since its initial release in 2002, .NET has changed significantly, becoming the foundation for a new generation of Windows applications. The .NET Framework and Visual Studio, the two core aspects of this initiative, provide a multilanguage environment in which developers can create Web services, graphical user interfaces, and other kinds of applications. Taken as a whole, the .NET technologies have changed the way nearly every Windows application is built. Now fully updated for version 2.0 of the .NET Framework and Visual Basic 2005, Understanding .NET, Second Edition, is a concise guide to the landscape of Windows development. Margin notes, detailed diagrams, and lucid writing make this book easy to read and navigate, while analysis sections explore controversial issues and address common concerns. David Chappell's independent perspective and straightforward descriptions clarify both how the .NET technologies work and how they can be used. Coverage includes: An overview of .NET and its goals The Common Language Runtime (CLR) The .NET languages, including C#, Visual Basic, and C++ The .NET Framework class library Building Web Applications with ASP.NET Accessing Data with ADO.NET .NET framework integration with SQL Server 2005 The key to using a new technology is to understand the fundamentals. This book provides the robust foundation developers and technical managers need to make the right decisions and maximize the potential of this revolutionary framework.

WCF Essentials-A Developer’s Primer
By:
Lowy, Juval
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2006 - May/June
Windows Communication Foundation (WCF) provides a run-time environment for your services, enabling you to expose CLR types as services and to consume services as CLR types.Although in theory you can build services without it, in practice, WCF significantly simplifies this task. WCF is Microsoft’s implementation of a set of industry standards defining service interactions, type conversion, marshaling, and various protocols’ management. Because of that, WCF provides interoperability between services, and it promotes productivity, including the essential off-the-shelf plumbing required by almost any application. This article describes the essential concepts and building blocks of WCF and its architecture, enabling you to build simple services. Future articles in this series will address specific aspects, such as transaction management and security.

LINQ

Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2006 - March/April, Markus Egger Talks Tech, VFP Conversion Papers
At PDC 2005, Microsoft introduced brand new technology known as LINQ, which stands for “Language Integrated Query.”The feature-set hiding behind this acronym is truly mind-boggling and worthy of a lot of attention. In short, LINQ introduces a query language similar to SQL Server’s T-SQL, in C# and VB.NET. Imagine that you could issue something like a “select * from customers” statement within C# or VB.NET. This sounds somewhat intriguing, but it doesn’t begin to communicate the power of LINQ.

Mobility is one of those fields which everybody knows is a definite part of our future, in 5 to 10 years or so. Think again.Amber steps out of her client's office, enters her car, pulls out her mobile phone and dials the number to her main office. She's calling Martin?her internal sales representative to inform him that she finally closed a deal with her client. She needs him to place an internal order at the warehouse. There are many items on that order, including 500 units of product X, configuration A. After a quick query in the central inventory management system, Martin informs her that there are only 250 units left of that configuration, but there are more than plenty for her order if the client would be willing to switch to configuration B. Amber now needs to call her client back and save the deal. The client will be very disappointed, the whole thing will have to be negotiated over the phone, and Amber will probably have to cut her margins or else she'll lose everything.

The Process class allows you to gain full control over system processes.You can start and stop processes and retrieve information about running processes such as the list of loaded modules and the characteristics of the memory occupied. The class also features handy methods to know whether a process is responding or has just exited and with which return code. Programmers also have full control over the style of the window the process runs in. After an overview of the capabilities of the Process class, this article demonstrates how to hide running console processes, monitor their execution, and capture any output. I'll use this strategy to create a sample Compression class to use with WinZip and gzip (popular tools for compressing data).

Publishing Performance Data From Your .NET Applications

Last updated: Wednesday, August 31, 2022
Published in: CODE Magazine: 2004 - March/April
You always want the software you write to have great performance.The reason isn't shocking?users look to software to quickly and efficiently handle their workload. Often times, meeting this performance requirement (whether it is explicit or implied), can be a difficult, even daunting task. Tuning an application to perform at its peak level involves a thorough understanding of the architecture and environment into which you will deploy your application. However, you can't truly begin to optimize an application's performance if you don't understand how to empirically measure that performance. From this perspective, your application must emit enough data to enable real time performance monitoring.

Visual Studio .NET provides an incredible leap forward from its predecessor in terms of functionality, but eventually, every developer finds a sought-after feature that just seems overlooked. VS.NET provides great features and capabilities, from intelligent wizards to very useful drag-and-drop functionality such as that provided by the Server Explorer tool window. If there's a problem, it could be one of too much success. A simple stroll through the IDE reveals feature after productivity-inducing feature, providing the developer with a high set of expectations. Eventually, you may find that an expected feature is missing. Fortunately, Microsoft included a very powerful extensibility model, allowing integration of new, custom features directly into the IDE.

In real-world applications you just can't do without encryption.The problem with cryptography, though, is that sometimes it may make you use an overly complex API. The .NET Framework classes for cryptography don't require you to become an expert mathematician or a cryptography guru. In the .NET Framework you'll find symmetric and asymmetric cryptographic providers as well as hash providers. Some of these provider classes end up calling into the unmanaged CryptoAPI library while other parts of the .NET cryptography solution are purely managed code.

The complex, component-style development that businesses expect out of modern software developers requires greater design flexibility than the design methodologies of the past. Microsoft's .NET Framework makes extensive use of attributes to provide added functionality through what is known as "declarative" programming. Attributes enhance flexibility in software systems because they promote loose coupling of functionality. Because you can create your own custom attribute classes and then act upon them, you can leverage the loose coupling power of attributes for your own purposes.

When you make a method call on an object, typically you must block the client while the object executes the call, and control returns to the client only when the method completes execution and returns.However, there are quite a few cases where you want to call methods asynchronously?that is, you want control to return immediately to the client while the object executes the called method in the background, and then somehow let the client know when the method execution is completed. Such an execution mode is called asynchronous method invocation and the action is an asynchronous call. Asynchronous calls allow you to improve availability, increase throughput and performance, and make your applications more scalable.

The .NET File System Object Model
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2003 - May/June
The .NET Framework doesn't change the structure of the file system, nor does it build a new layer on top of it.More simply, but also more effectively for developers, it supplies a new object model for file system-related operations. A managed application can work with files and directories using high-level methods rather than low level understanding of the file system. This article provides an overview of methods and classes contained in the System.IO namespace.

Using the ASP.NET Runtime to Extend Desktop Applications with HTML Scripts
By:
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2003 - March/April
People often think of HTML as the sole domain for Web applications.But HTML's versatile display attributes are also very useful for handling data display of all sorts in desktop applications. The Visual Studio .NET start page is a good example. Coupled with a scripting/template mechanism you can build highly extendable applications that would be very difficult to build using standard Windows controls. In this article, Rick introduces how to host the ASP.NET runtime in desktop applications and utilize this technology in a completely client-side application using the Web Browser control.

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.

Working with Extender Classes
By:
Last updated: Wednesday, August 31, 2022
Published in: CODE Magazine: 2003 - January/February
Extender classes do just that; they allow you to extend the functionality of a .NET control class. The Error Provider and Tooltip classes are two examples of extender classes in the .NET Framework. The Tooltip class represents a significant departure from how tooltips were implemented in earlier versions of Visual Studio. The Error Provider class provides a new way to inform users about invalid input. Although each class serves a different purpose, their implementation is quite similar. This article introduces these two classes and gives a brief, yet comprehensive primer on how to use them

End DLL Hell with .NET Version Control and Code Sharing
By:
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2002 - July/August
Component-oriented programming must allow for clients and components to evolve separately.Component developers should be able to deploy new versions (or just defect fixes) of existing components without affecting existing client applications. Client developers should be able to deploy new versions of the client application and expect it to work with older component versions. As a component technology, .NET must enforce version control, allowing for separate evolution paths and for side-by-side deployment of different versions of the same component. .NET should also detect incompatibility as soon as possible and alert the client.

Retrieving HTTP content in .NET
By:
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2002 - May/June
HTTP content retrieval is an important component for applications these days.Although .NET reduces the need to explicitly retrieve content from the Web through built-in mechanisms in the Web Services framework, ADO.NET and the XML classes, there are still many needs to retrieve Web content directly and manipulate it as text or data downloaded into files. In this article, I will describe the functionality of the HttpWebRequest and HttpWebResponse classes and provide an easy to use wrapper class. The class simplifies the HTTP access and provides most of the common features in a single interface while still providing full access to the base functionality of the HttpWebRequest class. In the process, I will describe some sticky issues like string encoding and Cookie handling and some related topics like implementing events and running multiple threads to service Web requests.

Custom .NET Windows Forms Controls
By:
Patel, Kamal
Last updated: Friday, October 28, 2022
Published in: CODE Magazine: 2002 - January/February
The .Net framework provides two base classes for controls; one for Windows forms and the other for ASP.NET server controls.We can extend the existing controls by adding specific functionality to them or develop our own controls from scratch. Such controls are called custom controls. We can also group controls together and create another control, such as an address box, that contains couple of textboxes and labels. Controls that are grouped together and are based on System.Winforms.UserControl are called user controls. This article explains the process of creating a user control and demonstrates how we can extend the functionality of the framework's DateTimePicker control.

Visual Studio Platform and Extensibility
By:
Novak, Istvan
Last updated: Tuesday, February 19, 2019
Published in: Publisher's Point
As a .NET architect and developer I cannot imagine my everyday work without Visual Studio. I was always in a strange excitement when waiting for a new CTP, Beta or RTM of Visual Studio because I always expected some great new features with every release. During the years I have bought a few third-party add-ins and utilities for Visual Studio to make my development tasks easier and even created small add-ins to produce some useful piece of code. I knew that Visual Studio was extensible; I downloaded the SDKs and tried to get familiar with those hundreds of extensibility interfaces. However, due to lack of good documentation I often got frustrated.
