User Defined Functions in VBScript

 User Defined Functions in VBScript

 VBScript Functions

> In Structured Programming (Ex: C Language) we use Functions (Built-in and user defined).

> In Object Oriented Programming (ex: Java) we use Methods (Built-in and user defined).

> In VBScript we use Functions and Methods (Object based language).

What is Function?

A reusable code.

When we choose Functions?

Whenever we want to perform any operation multiple times then we choose Functions.

Types of Functions in VBScript:
i) Built-in Functions

Array Functions
Date & Time Functions
String Functions
Conversion Functions
Math Functions
Miscellaneous Functions

ii) User defined Functions

Sub Procedures (Public/Private, Internal/External)
Function Procedures (Public/Private, Internal/External)

Public and Private – Access Modifiers

Internal Function – Defining and Calling within the Script

External Function – Calling from external Resource (Ex: Function Library)

a) Sub Procedures:

Set of Statements enclosed with Sub and End Sub statements to perform an operation.

Sub Procedures take Arguments but Arguments are optional.

Sub Procedures Won’t return any value.

Syntax:

Sub ProcedureName (Arguments)
Statements

End Sub

b) Function Procedures

Set of Statements enclosed with Function and End Function Statements to perform an operation.

Function Procedures take Arguments but Arguments are optional.

Function Procedures can return a value.

Note: Sub Procedures are faster in execution than Function procedures.

Syntax:

Function procedurename (Arguments)
Statements

———–
————-

End Function

Calling Functions

Call FunctionName(Values)

VBScript User defined Function Examples:

1) Sub / Function procedure with No Arguments

2) Sub / Function procedure with Arguments

3) Sub / Function procedure with Arguments and Loading Shared Object Repository at run-time.

4) Sub / Function procedure with Arguments and Verification point

5) Sub / Function procedure for Data driven Testing

6) Function with Returning a Value

7) Function with Returning multiple values

8) Calling Sub procedure/Function Procedure within a Function
