Since the release of .NET 1.0 more than ten years ago, the classes governing identity have remained unchanged. That’s a good thing, because identity and security is at the core of most applications, so you don’t want that to change very often. However, with the release of .NET 4.5, the identity model has changed significantly.

I have a client that has a few Windows Services and some EXEs that run on a computer to perform various business functions. Every once in a while, the processes fail and need to be restarted. I helped the client write a Windows Service to monitor their running processes and ensure that they are up and running and to notify them and to attempt to restart those processes. As part of this process, I had to write a class to get a list of all of the processes running on the current computer or on another computer on their network.

In this article, you will create a CODE Framework RESTful service and an iPhone application from scratch. For the client side, you will utilize XCode (yes, you’ll need a Mac!), which uses Objective-C as the primary language. This article won’t teach you the language; you need to know the basics of Objective-C. Even if you don’t know anything about it but want to code right away, read the article “Building a Twitter Search Client on iOS,” by Ben Scherman, available for all CODE readers in the Xiine application for Windows, Android, and iPhone. For the database, you’ll use any instance of SQL Server 2008.

CODE Framework: Documents, Printing, and Interactive Document UIs
By:
Last updated: Monday, June 6, 2022
Published in: VFP Conversion Papers, Markus Egger Talks Tech, CODE Magazine: 2013 - March/April
The CODE Framework WPF features (based on MVVM and MVC concepts) have become very popular amongst .NET developers, thanks to ease of development paired with a high degree of freedom, control and reuse. Another CODE Framework module takes these concepts and extends them into the domain of documents and printing. Many applications use third-party reporting products to create print and report output, and those products certainly have a good reason for existence and aren’t entirely replaced by the CODE Framework Document features. However, the CODE Framework Document features can replace some functionality that would otherwise be handled by reporting packages, and in addition, the CODE Framework Document features add a significant number of new features including the ability to create more naturally flowing documents and printouts and use those not just for print, but also use them as interactive user interfaces.

Workflows in SharePoint 2013, Part 1

Last updated: Thursday, June 9, 2022
Published in: CODE Magazine: 2013 - January/February
If we have been friends for a while, you must know my opinions about workflows in SharePoint 2010 and SharePoint 2007. I didn’t think they were very good, especially from a performance and scalability point of view. Frankly I think Microsoft should have called them “workslows.” Though, I don’t think it was the implementation in SharePoint that was the issue, it was fundamental issues with Workflow Foundation, compounded by the nature of SharePoint that acerbated the issues. Well, I am happy to say that Workflows in SharePoint 2013 are something I feel quite comfortable recommending to anyone, and I hope to make that case in this article.

LINQ to XML Instead of a Database
By:
Last updated: Wednesday, February 20, 2019
Published in: CODE Magazine: 2012 - September/October
When people think of having to store data for their applications, a database such as SQL Server immediately comes to mind. However, XML files are very handy for storing data without the overhead of a database. Using XML files to cache often-used, but seldom changed data such as US state codes, employee types and other validation tables can avoid network roundtrips and speed up your application. In addition, XML files are great for off-line applications where a user needs to add, edit and delete data when they can’t connect to a database.

SharePoint Applied: Large Files in SharePoint 2010
By:
Last updated: Wednesday, February 20, 2019
Published in: CODE Magazine: 2012 - July/August
When a team at Microsoft first conceived of SharePoint, the product team decided that the content database was the best place to store file uploads in SharePoint. Before you pull out daggers, consider that there were many advantages to this choice. You can never have a virus corrupting the server in an upload that goes into the database. No filename issues. Transaction support. Easy backups, etc. Also, believe it or not, for a certain file size (smaller the better), databases can actually offer better performance than traditional file systems for storage. In addition, the product team decided to rely heavily on GUIDs and clustered indexes inside the content database - again, a choice with positives and negatives.

Although Web API currently ships and installs with ASP.NET MVC 4, you can use Web API functionality in any ASP.NET project, including WebForms, WebPages and MVC or none of the above. You can also self-host Web API in your own applications.

Grokking the DLR: Why it’s Not Just for Dynamic Languages
By:
Kevin Hazzard
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2012 - May/June
Many .NET developers have heard of the Dynamic Language Runtime (DLR) but they don’t quite know what to make of it. Developers working in languages like C# and Visual Basic sometimes shirk dynamic programming languages because they fear the scalability problems that have historically been associated with using them. Also of concern is the fact that languages like Python and Ruby don’t perform compile-time type checking, which can lead to runtime errors that are very costly to find and fix. These are valid concerns that may explain why the DLR hasn’t enjoyed more popularity among mainstream .NET developers in the two years since its official release. After all, any .NET Runtime that has the words Dynamic and Language in its title must be strictly for creating and supporting languages like Python, right?

No, the title isn’t a misprint-this installment of the Baker’s Dozen will visit both sides of the planet. These days, many .NET user group meetings focus on database and business intelligence topics as well as hardcore .NET content. Over the last several months, I’ve spent roughly half my time modifying my own development framework for WCF. The result is some basic but functional factory classes I’d like to share. The other half of the time, I’ve been looking at different capabilities in the SQL Server 2005 and 2008 Business Intelligence stack, and solving requirements that BI developers often face. So rather than pick one side and make the other side wait two months, I decided to combine the two.

From Delegate to Lambda
By:
Blomsma, Mark
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2008 - September/October
The key to understanding lambda expressions is understanding delegates. Delegates play a tremendously important role in developing applications for the .NET Framework, especially when using C# or Visual Basic. Events, a special application of delegates, are used all over the framework. And the application and possibilities of delegates has only grown over time. C# 2.0 introduced the concept of anonymous methods and C# 3.0 and VB 9 take anonymous methods to the next level with lambda expressions. This article reviews the evolution of delegates and examines possibilities and syntax of delegates and lambdas in .NET 3.5.

The Baker’s Dozen: A 13-Step Crash Course for Using LINQ
By:
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.

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.

For Visual FoxPro developers, data access represents the daily bread and butter. Data access is a core feature of Visual FoxPro (which after all is an xBase descendent) and nobody gives much thought to the ability to run a select-statement right within a VFP program.Most languages however (including .NET languages such as C# or Visual Basic .NET) are not as data centric and thus do not support data manipulation as a core language concept. At least until now. But all this is about to change with the introduction of LINQ.

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.

Configuration settings make it possible for users and administrators to configure an application before it is run for the first time and while it runs..NET provides a good rudimentary mechanism for storing and retrieving configuration settings in the application's .config file with the ConfigurationSettings class, but this mechanism is missing a number of essential features. This article describes how to improve on the base functionality using a class that provides strong typing, allows for writing of keys, and provides optional encryption of keys.

Data-bound controls play a key role in the development of ASP.NET applications. Data-driven controls allow you to associate their whole interface, or individual properties, with one or more columns of a .NET-compliant data source. In this article, I'll delve into the depths of an extremely versatile data-bound control that is a fixed resence in any real-world ASP.NET application - the DataGrid control. I'll focus on the key programming aspects of the control, including data binding, column mapping, paging, and sorting.

At PDC 2005, Microsoft announced a new technology called Language Integrated Query (LINQ), which will be available with Visual Studio “Orcas” (the next version of Visual Studio). A lot of exciting new technologies are announced at every PDC, and as a result, LINQ got some attention, but not nearly as much as I think it deserves. LINQ represents the ability to run queries right inside of Visual Basic, C#, or any other .NET language.

What's New in Visual Studio .NET 1.1?
By:
Lowy, Juval
Last updated: Thursday, February 21, 2019
Published in: CODE Magazine: 2003 - March/April, VFP Conversion Papers
Visual Studio .NET provides a new set of features designed to improve and enhance the development experience. Most of these changes have to do with user ergonomics and are typical of a minor release of a Visual Studio product. Only a few of the changes are related to the underlying platform. This article assumes you are familiar with Visual Studio .NET 1.0 and it presents only the new features of the IDE (Integrated Development Environment) of Visual Studio .NET 1.1, for both C# and Visual Basic .NET. J# is not discussed because it was not part of Visual Studio .NET 1.0. In the interest of space, some minor cosmetic changes (such as reorganization of the Start page) are not listed.

Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2004 - May/June
Building an audit trail into your application provides a mechanism for tracking who updated what when, and the new generics feature in Whidbey helps you build that trail.The Whidbey release of .NET will include a new Common Language Runtime (CLR) feature called generics. Generics allow you to use a variable to represent a desired data type, and thereby create very generic code (hence the name) that works with any data type.You define the data type for the generic variable at run time and the CLR substitutes that data type for the variable everywhere in the code that it is used; basically providing you with strongly typed generic code.

Asynchronous Windows Forms Programming
By:
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2004 - March/April
Windows Forms applications often require some sort of asynchronous invocation option.You rarely want to block the user interface while a lengthy operation executes in the background. Windows Forms pose a set of complicated design and implementation issues when it comes to asynchronous method invocation and multithreading due to the underlying Windows messages processing. Although .NET does provide a uniform asynchronous invocation mechanism (described in my article, "Asynchronous .NET Programming", CoDe Magazine, May 2003) you cannot apply it as-is in a Windows Forms application. To address this problem, the next version of .NET (version 2.0, code-name Whidbey) provides a new component designed to ease the task of developing asynchronous Windows Forms applications. This article starts by describing the current asynchronous programming model available to Windows Forms developers. Then, not only does this article describe the Whidbey solution, it also provides a .NET 1.1 implementation of the solution so that you can take advantage of this superior programming model today and ease the transition into Windows Forms 2.0 in the future.

C# 2.0 Code Refactoring
By:
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2004 - January/February
The next version of C# will feature a code refactoring engine built into the Visual Studio environment.A term coined by Martin Fowler, code refactoring allows you to change the code structure without changing or affecting what the code itself actually does. For example, changing a variable name or packaging a few lines of code into a method are code refactoring. The main difference between C# 2.0 refactoring and a mere edit or find-and-replace is that you can harness the intelligence of the compiler to distinguish between code and comments, and so on. This article provides a preview of Visual C# 2.0 code refactoring, to be released with the next version of Visual Studio .NET, code-name Whidbey.

Brian Kernighan [1] once said, "Debugging is twice as hard as writing code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it." This quote gets a little giggle out of most developers, but on the serious side, there is a lot of truth in it. Writing code that does cool or useful things certainly is much easier than writing code that does cool or useful things reliably.

Since the earliest versions of the Windows operating system, all Windows have been rectangular.However, the number of applications that break out of this boring mold is rising. Even Microsoft, the king of rectangularity, is starting to create applications that use shaped windows, such as Media Player. Unfortunately, creating shaped forms has always been quite tricky. Until now that is! The .NET Framework and the Windows Forms package in particular make it easy to produce forms that have rather sophisticated shapes.

In graphical user interfaces such as Microsoft Windows, drawing on the screen is an important task.Everything displayed on the screen is based on simple drawing operations. Often, environments such as Visual Basic abstract those drawing operations away from the developer. However, the same drawing operations still take place under the hood. In Visual Studio .NET, developers have easy access to that drawing functionality whenever they need it through a technology called GDI+. Using GDI+, developers can easily perform drawing operations such as generating graphs or building custom controls.

Web services are all about connecting businesses in a standard and secure manner.For a real-life Web service, security is intrinsic to every facet of operation and no party would ever agree to interact with a non-secure Web service. Unfortunately, Web services security is still in its infancy; standards such as WS-I are just emerging and there is no built-in support in the development tools for them. That being said, there are quite a few programming techniques you can use today in .NET 1.1 to secure your Web services, and do so in a way that will ease the transition to future standards and protocols.

Cryptography the .NET Way
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2003 - July/August
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.

Tansey, David
Last updated: Wednesday, August 31, 2022
Published in: CODE Magazine: 2003 - July/August
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.

Asynchronous Calls in .NET
By:
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2003 - May/June
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.

There was a time, not too long ago, when browser-based user interfaces were considered both the status quo and the Next Great Thing.The demand for Windows Forms-based applications started to dwindle as the developer community fully embraced browser/server applications with their centralized server components and ubiquitous user interfaces. .NET, however, brings a much more powerful library of distributed communication technologies (such as Web services and remoting). As a result, .NET developers are seeing some of these traditionally browser-based applications becoming, more simply, Web-enabled and less tied to a browser. In short, developers can now see a very real business case for building distributed applications on Windows Forms technology.

.NET Interface-based Programming
By:
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2002 - May/June
In component-based programming, the basic unit of use in an application is a binary-compatible interface.The interface provides an abstract service definition between the client and the object. This is in contrast to the object-oriented view of the world that places the object implementing the interface at the center. An interface is a logical grouping of method definitions that acts as the contract between the client and the service provider. Each provider is free to provide its own interpretation of the interface and its own implementation. To use a component, the client only needs to know the interface definition and have a binary component that implements that interface. This extra level of indirection between the client and the object provides for interchangeability between different implementations of the same interface, without affecting client code.

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.

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.
