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 :

Inorder 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 :

Inorder 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.
