What is an Object

VBScript runtime objects help us to accomplish various tasks. This section will help you understand how to instantiate an object and work with it.

Syntax

In order to work with objects seamlessly, we need to declare the object and instantiate it using Set Keyword.

Dim objectname    'Declare the object name
Set objectname = CreateObject(object_type)

Example

In the below example, we are creating an object of type Scripting.Dictionary.

Dim obj  
Set obj = CreateObject("Scripting.Dictionary")

Destroying the Objects

The significance of destroying the Object is to free the memory and reset the object variable.

Syntax

In order to destroy the objects, we need to use Set Keyword followed by the object name and point it to Nothing.

Set objectname = Nothing 'Destroy the object.

Example

In the below example, we are creating an object of type Scripting.Dictionary.

Dim obj  
Set obj = CreateObject("Scripting.Dictionary")
Set obj = Nothing.
