Re: IsNothing(_myVar) vs. _myVar Is Nothing

Dave,

To tell the same as Jay in other words.

The IsNothing is a function in the Microsoft.VisualBasic namespace. The
Microsoft.VisualBasic namespace is a namespace included in the framework and
although it is named Microsoft.VisualBasic namespace usable by every managed
program language (C#, J# and C++ managed).

It gives a lot of handy functions, often it are *only* wrappers around
functions in System.Net while mostly it includes as well optimizing code
(even if that optimizing is helping you to write less code).

Here is as Jay showed by the ILS probably nothing more than a wrapper.

About the 80/20 I agree completly with Jay.

I hope this explains it even more.
