Is there more than one version of Visual Basic?

Yes. Since 1991 when it was first introduced by Microsoft, there have been nine versions of Visual Basic up to VB.NET 2005, the current version. The first six versions were all called Visual Basic. In 2002, Microsoft introduced Visual Basic .NET 1.0, a completely redesigned and rewritten version that was a key part of a much larger computer architecture. The first six versions were all "backward compatible". That means that later versions of VB could handle programs written with an earlier version. Because the .NET architecture was such a radical change, earlier versions of Visual Basic have to be rewritten before they can be used with .NET. Many programmers still prefer Visual Basic 6.0 and a few use even earlier versions.
