There is no difference with value types (Integer, Double, Structures, ...).
The instance is created anyway in both cases.

There is a difference with reference types: Without new, only the space for
the variable is reserved (currently 4 bytes = 32 bits). No object is
created. The variable contains Nothing (= no reference). With New, it is
equal to
dim o as type
o = new type
which means it also creates an object and stores the reference to the object
in o.

How to quote and why:

Dim objSome as Something

-This declare the objSome but memory was not allocated.

Dim objSome as new Something

-This declare and allocate memory for the object.

:new is the keyword in .net to allocate memory for the declared object.
