Visual Basic .NET developers continue to struggle to remain loyal to VB. They know intellectually that VB is truly a first-class language in .NET but somehow they still don't quite believe it.

Object-oriented (OO) programming was finally a possibility. Unfortunately, few OO features were included in the VB language at that point. Most notably lacking were inheritance capabilities, one of the key defining criteria for any OO language.

When I reread my initial article, "Creating a Server Component with Visual Basic" (see http://www.15seconds.com/Issue/980930.htm ), it struck me that a lot of code has flowed under the bridge since then.

Although not especially good at pointers and addresses, VB.NET and C# enable a developer to emulate, contrive, or precisely reproduce almost everything else that even the most complex languages, like C++, offer. One such construct is the union. A union is like a structure, but it permits all its fields to share the same starting address. Consider a union with character and integer fields. The union... http://www.oreillynet.com/pub/a/dotnet/2002/09/22/vb-oop.html by Budi Kurniawan 09/23/2002 Visual Basic .NET offers its users, among many other things, a fully object-oriented programming (OOP) experience. Some former VB6 developers have prepared themselves well to embrace this new version of the language. Others, however, need more time and guidance in taking on this new challenge and opportunity. In this VB.NET OOP series, Budi Kurniawan introduces many facets of object-oriented design and programming to VB programmers new to OOP.
