Today's Hardware Friday post is kind of thing that many gamers lust for, a hardware extension for their simulator of choice, be it as complicated as a airplane cockpit in their garage or something a little more approachable like a DIY hardware dashboard for your racing simulator.DIY DashboardThe…

Today's Hardware Friday post is another Kinect related project, but this time using a couple things we don't see much in the Kinect space, Ardunio and Visual Basic!Kinect controls Arduino wired Servos using Visual Basic 2010In this project, I use left and right hand movements in Kinect to control…

In this final video, Bob talks about approaches to solving common issues that arise for new software developers, where to turn for help, how to search for answers to technical questions, how to ask for help and become part of the .NET community, how to create a personal knowledge base of books and…

This video demonstrates the use of the My Namespace in Visual Basic which provides a short-cut to often used classes in the .NET Framework Class Library.  We demonstrate how to use the My Namespace to retrieve information about the user's computer, search for files on the file system, perform…

In this lesson we demonstrate how events are utilized in the .NET Framework Class Library specific to Silverlight, WPF and ASP.NET Web Forms applications. In all three examples, we see how Visual Basic is generated by the IDE to "wire up" a user action or application event to code that…

Building on the work from the previous lesson with generic collections, in this lesson we start by talking about how Structured Query Language provides a means of working with sets (collections, groupings, etc.) of data. In a similar way, the LINQ syntax provides a simple way of working with groups…

Collections are a more powerful form of arrays. In this lesson we demonstrate an "old style" collection (pointing out their limitations) as well as several of the newer, strongly typed generic collections (List(Of T) and Dictionary(Of T1, T2)) utilizing the generics syntax.Download the…

Exceptions occur when an application experiences some unexpected problem at run time. This lesson discusses how to use the try catch finally block to anticipate potential problems and attempt to shield the end user from those problems as much as is possible. We discuss best practices when checking…

Classes can contain many different types of information, not just Properties and Methods. We begin demonstrating the use of Enumerations because often in the .NET Framework Class Library, properties can only be set to a pre-determined subset of possible values. To illustrate this point we create our…

This lesson begins by discussing the scope of variables within code blocks, and progresses to explain how accessibility modifiers such as Public, Private and Protected are used by the .NET Framework Class Library to expose or hide implementation of their given services to consumers of that given…
