Hello:

How do I know when to use 'New' when declaring a variable? How do I know
when an instance can be created?

Ex:
Dim x As New System.Random
-versus-
Dim mailMessage As System.Web.Mail.SmtpMail (this produces an error!)

VS.Net 2003

Thanks.

Look in the documentation if the class has any public constructors.
SmtpMail doesn't have any public constructors, but you don't need it
since all its methods are Shared.
