Is Operator

Description

Used to compare two object reference variables.

Syntax

result = object1 Is object2

The Is operator syntax has these parts:

Remarks

If object1 and object2 both refer to the same object, result is True; if they do not, result is False. Two variables can be made to refer to the same object in several ways.

In the following example, A has been set to refer to the same object as B:

Set A = B

The following example makes A and B refer to the same object as C:

Set A = CB = C

' Assume MyObject <> OtherObject= MyObject Is ThatObject        ' Returns False.
