Returning a value from a Function in QTP

To return a value from a function, we need to take care of the following two things:

 1) To return a value from a function, you need to use the statement functionName = ReturnValue, where functionName is the actual name of the function and ReturnValue is the value you want to return.

 2) To capture the returned value, you need to use the statement someVariable =functionName(parameters) while calling the function.

Let us understand this with the help of an example.

Returning value from a Function

'==========================================================

'  Function Name:   fnSum(var1, var2)

'  Function Scope:   Public

'  Parameters:   var1 and var2- Enter a number , result will display Sum

'  Description:   To find addition of two numbers

'  Author      :   Hardeep

'==========================================================

Function fnSum(var1, var2)

vrSum = var1 + var2   'return the result

 fnSum = vrSum

'This Statement Returns the value from Function i.e. functionName = ReturnValue

End Function

'Calling the Function and capturing the return value in variable "vrResult"

Dim vrResult

vrResult =  fnSum(25,10) 

'parameters should be passed using parenthesis when the function returns a value
