- 10 Years of CODE
Friday, April 16, 2010
This is where you would normally expect our popular “Post Mortem” column: An interesting article that describes a project after it is complete and some interesting points about things that went well and things that didn’t. This month is different, however, because this is the 10-year anniversary edition of CODE Magazine! So while CODE Magazine isn’t a project that is “complete” and we certainly expect the magazine to continue on for a long time to come (both in print and online), let’s take a look back and recap what has transpired!

- Building Polished UIs with Expression Blend - Part 1
Friday, February 27, 2009
With WPF and Silverlight, Microsoft provides both Windows and Web developers with powerful technologies to create rich, professional, and exciting user experiences.However, in general, developers aren’t graphical designers, leaving most developers wondering how to cope with this new world of designed interfaces and polished user experiences. But fear not! With Expression Blend, Microsoft provides a great tool to create such UIs, and even developers with no graphical talents whatsoever can learn a few techniques that allow for better looking applications.
- Comparing VFP String Performance to .NET String Performance
Wednesday, January 30, 2008
The series of test conducted here are based on the "String Processing with VFP" article published in the Spring 2000 issue of CoDe Magazine.
- A Silverlight to Illuminate the Path Ahead…
Monday, September 17, 2007
At Mix 2007 in Las Vegas, Microsoft announced Silverlight (formerly known as WPF/E) to much fanfare. Silverlight is very intriguing in concept, as it further travels the path previously laid out by WPF (Silverlight’s big brother), and it aims to bring the worlds of Windows and Web development, as well as the worlds of software development and graphical design, much closer together. As more and more details emerge (and the first released version is now available), it becomes clear that Silverlight is not just an intriguing concept, but it is for real! Markus discusses Silverlight concepts in this article.
- The Missing LINQ
Monday, January 29, 2007
Visual FoxPro’s (VFP) Data Manipulation Language (DML) is one of VFP’s most compelling features. It is also the most obvious feature VFP developers miss in .NET languages such as C# and Visual Basic. However, Language Integrated Query (LINQ), a new query language for .NET developers is a new feature in the upcoming releases of C# 3.and Visual Basic 9.0 that addresses these shortcomings.
- VFP Conversion Roadmap Whitepaper
Wednesday, November 29, 2006
This whitepaper discusses strategies for managers converting Visual FoxPro (VFP) applications to .NET, and lays a foundation for producing an implementation plan.
- Find New Meaning In Your Ink With Tablet PC APIs In Windows Vista
Monday, November 20, 2006
With Windows XP Tablet PC Edition, Microsoft introduced more than just a powerful platform for users. Through the associated SDKs, Microsoft has also empowered developers to create advanced ink-enabled applications.Recognizer objects provide the means to recognize handwriting as text. Similarly, gestures can be recognized and interpreted in any way the developer desires. Other objects allow for the division of digital ink into paragraphs, lines, and segments. The combination of these objects allow for the creation of very advanced applications. However, these options do not cover the complete range of features needed to create next-generation ink-enabled applications.
- Windows Presentation Foundation - an Introduction for VFP Developers
Monday, November 20, 2006
The Windows Presentation Foundation (short WPF) is coming, and it will replace all Windows UIs as we know them today.This means that no developer can ignore this technology. This article provides an introduction to WPF both from a general point of view as well as from a Visual FoxPro specific angle.
- .NET Data Access with LINQ: A VFP Perspective
Monday, November 20, 2006
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.

Monday, February 06, 2006
Markus Egger discusses tools used to create WPF (Windows Presentation Foundation, formerly "Avalon") interfaces, in particular, WinFX Extensions for Visual Studio as well as the Microsoft Expression product line.
- LINQ
Wednesday, February 01, 2006
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.
- Into the Future
Friday, December 30, 2005
Tablet PC and Mobile PC development is very popular today, and it will get more popular and important in the future.For Mobile PC developers, there are significant changes coming in the near future, some in the Windows XP timeframe, others in Windows Vista. This article provides an overview over what’s on the drawing board or already available in technology preview builds.
- Introduction to Tablet PC Development
Friday, December 30, 2005
If you are familiar with development on PCs using Microsoft’s tools, you know most of what you need to develop for Tablet PCs.The main addition in the Tablet PC development arena is that of Digital Ink and the features that go along with it, such as Ink collection, Ink management, and Ink recognition. There are also a few minor additional things, such as new user interface considerations and screen operation in portrait mode.
- Ink Recognition and Ink Analysis
Friday, December 30, 2005
Being able to take handwritten notes or annotations is nice, but the real power of Tablet PCs comes from the ability to analyze and recognize digital Ink.Recognition of handwriting is important as it allows for the conversion of digital Ink into standard text strings. Ink analysis takes the concept a step further and adds spatial interpretation to the mix to apply further semantics. Gesture recognition enables the user to trigger real-time actions.
- Get Control and Performance with the Real Time Stylus API
Friday, December 30, 2005
Standard Ink collection is incredibly easy using the Tablet PC SDK.For scenarios that require more control or non-default behavior, default Ink collection may not be the best choice. The Real Time Stylus API provides lower-level, higher performance access to stylus input, making this the API of choice for power-developers.Standard Ink collection is incredibly easy using the Tablet PC SDK.For scenarios that require more control or non-default behavior, default Ink collection may not be the best choice. The Real Time Stylus API provides lower-level, higher performance access to stylus input, making this the API of choice for power-developers.
- Unveiling Windows SideShow
Friday, December 30, 2005
Windows SideShow enables users to use PCs even when they are turned off.SideShow allows users to remotely control PCs and servers. It allows PCs to create interactive output on devices other than monitors so users can view useful data stored on their PCs when they are away from it. It enables users to interact with their PCs in scenarios that would previously have been very cumbersome, and allows for the creation of secondary display and interaction devices that would previously have been cost-prohibitive.
- LINQ Up!
Monday, December 19, 2005
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.
- C-Sharpest
Sunday, December 04, 2005
C# 2.0 just shipped with a number of interesting new features: anonymous methods, nullable objects, iterators, partial classes, generics, and others. But the innovation does not stop there! Microsoft (and Anders Hejlsberg in particular) have already allowed us a sneak peek at some of the new features that will be available in C# 3.0.

- Pest Control
Monday, February 07, 2005
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.
- The Revenge of the Thick Client
Thursday, January 20, 2005
If you have been involved in a new software development project during the last five years ? and if you read this article, chances are you have ? then you have probably been faced with the question "Web application or Windows® UI?" And in the vast majority of cases, the answer to this question was probably "Web application." For modern, enterprise-wide systems there were simply many reasons and issues that made it hard to implement the desired feature set in a conventional Windows application and deploy it in a reasonable manner. At this point, the advantages and disadvantages of each application type are well understood, and decisions are easy to make. Or are they?
- Great Reasons to Ring In 2005!
Thursday, January 06, 2005
Wow, another year has gone by, and as you read this, you are probably returning to the office after a few more or less relaxing holiday time spent with friends and family and a New Year's celebration. Interesting things have happened in our industry in the last 12 months, but I predict that the next 12 months will be quite a bit more interesting! Seldom before have I been as excited about new technologies and developments as I am now.

- The Importance of the Managed Platform
Tuesday, August 31, 2004
.Net is a maturing platform. The first .NET alphas and betas went to a selected group of people years and years ago. At this point, we are approaching the third major installment of Visual Studio .NET (now called "Visual Studio 2005"). Surely at this point, nobody has to explain what .NET and the Managed Platform is. Or do we?

- Three Cool New Features in C#
Thursday, January 01, 2004
C# has always had a reputation as a clean language with lots of innovation.The Whidbey-release of Visual Studio .NET ships with a new version of the C# compiler that has a number of great new features. Some of them will be implemented as generic runtime features that will show up in other languages as well, and some are truly C#-specific. All of them originated in the C# camp. In this article, I will shed some light on my three favorite new features.
- Creating Tablet PC Applications with VS .NET
Monday, September 01, 2003
In the Fall of 2002, Microsoft introduced Tablet PCs based on the popular Windows XP operating system.By default, this new platform includes applications with special Tablet PC features enabled, such as Ink Input and Pen-based operation. In order for this platform to become truly popular, third-party vendors will also have to ink-enable their applications. Luckily, this is a pretty straightforward task.
- Using GDI+ in ASP.NET Web Applications, Part 2
Tuesday, July 01, 2003
In the last issue, I investigated GDI+ and how to use it for image manipulation in Web applications.This time around, I will look at the generation of brand new images using the same GDI+ technology and features.
- Event Binding in VFP 8
Sunday, June 01, 2003
Visual FoxPro developers have been using an event-based methodology for a very long time.For most purposes, events are what drive the development effort. The user clicks a button, causing an event to fire, and the developer writes code to react accordingly. All of this happens very transparently and without difficulty for either party. However, from a developer's point of view, there also isn't much flexibility in this approach. But in VFP 8, event handling is changing for the better.
- Structured Error Handling in VFP 8
Sunday, June 01, 2003
With the introduction of Visual FoxPro 3.0, error handling in VFP changed substantially.Rather than using "on error" statements, "state of the art" error events became available. Now, 7 years later, more sophisticated error handling mechanisms take center stage as Visual FoxPro 8.0 introduces structured error handling.
- The Basics of GDI+
Thursday, May 01, 2003
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.
- Using GDI+ in ASP.NET Web Applications, Part 1
Thursday, May 01, 2003
GDI+ is a technology that developers generally associate with Windows Forms applications because they use it to draw anything on the screen from custom controls to diagrams.However, you can also use GDI+ in ASP.NET Web applications whenever you want to serve up dynamic images. You can use GDI+ to create dynamic banners, photo albums, graphs, diagrams, and more.
- Shaped .NET Windows Forms
Wednesday, January 01, 2003
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.

- The Power of Inheritance in .NET
Tuesday, January 01, 2002
Inheritance is one of the most fascinating features in the Visual Studio.NET languages. We have discussed this feature in several articles in the past, mainly to explain the basic concepts. Now we are going to take a look at what inheritance can actually do for you, rather than how it works.
- Understanding Visual Inheritance in .NET
Sunday, April 01, 2001
Inheritance is the single most important new object-oriented feature in Visual Studio.NET. Surprisingly, not much has been written about the subject, and most of the information available is either very basic and an "overview" at best, or just plain misleading. In this article, I give you a real-world overview of what inheritance - especially visual inheritance, can do for you.
- Introducing .NET My Services
Monday, April 15, 2002
.NET My Services is Microsoft's first attempt at creating a professional, commercial and widely available Web Services platform.The .NET My Services umbrella hosts a number of different Web services, such as a Calendar service, a Contacts repository, and much, much more. These services are major building blocks for the "Everywhere, Anytime" vision, but best of all, they are relatively easy to implement and use in your own applications and Web sites!

- XML, XSL and HTML in Windows Applications
Monday, January 15, 2001
HTML and XML have made the Internet what it is today, but both technologies are not necessarily tied to the Internet.Quite the contrary! Using HTML in regular Windows applications has always been a great alternative. Paired with XML and XSL, this technique is more powerful than ever, since there are a growing number of XML sources, such as SQL Server, Web Services, and XML-enabled Business Objects.
- Building a 21st Century Application
Sunday, April 15, 2001
In previous issues of Component Developer Magazine, we have introduced technologies such as Queued Components, COM+ Security, Loosely Coupled Events, SQL Server 2000 and BizTalk Server.Each of these represents a fascinating myriad of possibilities. But, how do you put all of them together to build a real-life, highly reliable, 100% available distributed application?
- Loosely Coupled Events With COM+
Saturday, April 15, 2000
COM+ introduces a new way to architect and extend applications:The COM+ Event Service. This service is extremely flexible and much easier to handle and maintain than all other COM based event models we've seen so far. They are especially useful for business events that can now be published throughout the system without losing any control over business rules.
- Creating Smart Interfaces with Smart Tags and VFP 7
Saturday, December 15, 2001
As developers, we're used to data sitting in tables and databases.However, this is not how data exists in the real world?it's merely how developers want data to appear. Typically, data resides in documents and forms, emails and spreadsheets. Smart Tags are Microsoft's first serious attempt to utilize that kind of information and make it available to knowledge workers in a sensible fashion.

Windows DNA (as well as the recently announced .NET), and component based development in general, are fascinating approaches to application development.They provide great flexibility, scalability and freedom of distribution. Unfortunately, there has been a substantial delay in the widespread implementation of DNA applications. Surprisingly, the responsibility for this delay seems to lie with developers...
- COM+ Queued Components
Sunday, October 15, 2000
Automatic asynchronous messaging is an important technique for scalable, component-based applications.Microsoft provided its first asynchronous messaging mechanism in the form of Microsoft Message Queue Server (MSMQ). This technology is the basis for Queued Components, a COM+ feature that makes asynchronous messaging as simple as calling regular COM Components.
- Implementing B2B Scenarios with Microsoft BizTalk Server 2000
Sunday, October 15, 2000
Business-To-Business (B2B) communications are rapidly becoming an essential component in today's economy.Some say B2B transactions will soon outnumber Business-To-Customer (B2C) transactions. While we have learned how to do B2C quite efficiently, B2B presents an entirely new set of challenges that we have yet to resolve. Previous attempts were successfully used, but were too expensive to be used as often as B2C. Microsoft tries to resolve this dilemma with Microsoft BizTalk Server 2000, and it is looking promising! This article provides a first in-depth overview.

- Data Access for Partially Connected Applications
Sunday, December 18, 2005
In all but the simplest applications, data is stored in a central location and accessed over a network.However, in many scenarios, distributed applications can not assume a certain kind of network connection, both in terms of performance and reliability. In scenarios where users access their applications on mobile PCs, network connections may not be available at all. This introduces relatively complex data access scenarios with which modern applications need to cope.
