Keep Software Simple
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2009 - May/June
A lot of programmers tend to over engineer their software solutions.In the course of my consulting, I have reviewed many applications from many companies. In many cases I find a lot of areas where the software was just too complex. The reasons for this are varied, but seem to be centered around a few main areas: inappropriate use of design patterns, the “not invented here” syndrome, and building a Cadillac when a Chevy would do the job. You can solve these issues in many ways. All it takes is a little bit of re-thinking on how you build software. This article offers guidance on some things you can do to simplify your software development process

Licensing and Obfuscation
Last updated: Tuesday, February 19, 2019

If you develop software for a living (and since you are reading this magazine, I assume you are), at some point you will most likely figure out how to protect your investment in that software. Two things you will need to do to accomplish this are to add licensing to your software, and to obfuscate your code so others cannot reverse engineer your hard work. These two tools are absolutely essential in your efforts to protect your software. This article will provide you with an overview on how you can use these tools to protect yourself from piracy.

LINQ to XML Instead of a Database
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.

Why Use WPF?
Last updated: Tuesday, February 19, 2019
Published in: CODE Magazine: 2009 - November/December
If you have not taken a look at Windows Presentation Foundation (WPF) yet, you really should. WPF is a great desktop development platform. Granted, all of the tools are not yet in place, but Microsoft is pouring millions of dollars into developing WPF tools. Microsoft now considers Windows Forms a legacy technology and they won’t update it within Visual Studio. These two reasons alone should be enough to convince you that need to start learning WPF right now.While WPF offers a new set of development tools, you’ll see a lot that looks familiar. You still have the typical desktop controls like text boxes, check boxes, radio buttons, etc. You still write the same C# or Visual Basic code. The major difference is how you layout the screens, control the look and feel of the controls, and some of the properties are a little different. This article will give you a good introduction to what WPF is all about without diving too deep.
