It has been said the Sir Isaac Newton was the last person to know everything. He was an accomplished
physicist (his three laws of motion were the basis of classical mechanics, which defined astrophysics for
three centuries), mathematician (he was one of the inventors of calculus and developed Newton ’ s
Method for finding roots of equations), astronomer, natural philosopher, and alchemist. He invented the
reflecting telescope, a theory of color, a law of cooling, and studied the speed of sound.
Just as important, he was born before relativity, quantum mechanics, gene sequencing, thermodynamics,
parallel computation, and a swarm of other extremely difficult branches of science.
If you ever used Visual Basic 3, you too could have known everything. Visual Basic 3 was a reasonably
small but powerful language. Visual Basic 4 added classes to the language and made Visual Basic much
more complicated. Versions 4, 5, and 6 added more support for database programming and other topics
such as custom controls, but Visual Basic was still a fairly understandable language, and if you took the
time you could become an expert in just about all of it.
Visual Basic .NET accelerated the expansion of Visual Basic tremendously. The .NET Framework added
powerful new tools to Visual Basic, but those tools came at the cost of increased complexity. Associated
technologies have been added to the language at an ever - increasing rate, so, today, it is impossible for
anyone to be an expert on every topic that deals with Visual Basic.
To cover every nook and cranny in Visual Basic you would need an in - depth understanding of database
technologies, custom controls, custom property editors, XML, cryptography, serialization, two - and
three - dimensional graphics, multi - threading, reflection, the code document object model (DOM), diagnostics,
globalization, Web Services, inter - process communication, work flow, Office, ASP, and much more.
