Functions

Sub procedure:
Sub: Declares the name, arguments and code that form the body of a Sub procedure.
Syntax:
Sub name [(arglist)]
   [statements]
   [Exit Sub]
   [statements]
End Sub
Arguments:

Public:	Indicates that the Sub procedure is accessible to all other procedures in all scripts.
Default:	Used only with the Public keyword in a Class block to indicate that the Sub procedure is the default method for the class. An error occurs if morethan one Default procedure is specified in a class.
Private:	Indicates that the Sub procedure is accessible only to other procedures in the script where it is declared.
name:	Name of the Sub; follows standard variable naming conventions.
arglist:	List of variables representing arguments that are passed to the Sub procedure when it is called. Commas separate multiple variables.
statements:	Any group of statements to be executed within the body of the Sub procedure.

Example:

Addition 5 , 4
 
Sub Addition( num1,num2)
 
Result=num1+num2
Msgbox  "The Sum of the numbers is    "  &  Result
 
End Sub

⇒Function:

Declares the name, arguments, and code that form the body of a Function procedure.
Syntax:
Function name [(arglist)]
   [statements]
   [name = expression]
   [Exit Function]
   [statements]
   [name = expression]
End Function
Arguments:

Public:	Indicates that the Function procedure is accessible to all other procedures in all scripts.
Default:	Used only with the Public keyword in a Class block to indicate that the Function procedure is the default methodfor the class. An error occurs ifmore than one Default procedure is specified in a class.
Private:	Indicates that the Function procedure is accessible only to other procedures in the script where it is declared or if the function is a member of aclass, and that the Function procedure is accessible only to other procedures in that class.
name:	Name of the Function; follows standard variable naming conventions.
arglist:	List of variables representing arguments that are passed to the Function procedure when it is called. Commas separate multiple variables.
statements:	Any group of statements to be executed within the body of the Function procedure.
expression:	Return value of the Function.

Example:

Result=Addition(5,4)

Msgbox  "The sum of the number is " & Result 

Function Addition( num1,num2) 
Addition=num1+num2 
End Function

⇒Call:
Transfers control to a Sub or Function procedure.
Syntax:
[Call] name [argumentlist]
Arguments:

Call:	(Optional) keyword, If specified, you must enclose argumentlist in parentheses.
name:	(Required) Name of the procedure to call.
argument list:	(Optional) Comma-delimited list of variables, arrays, or expressions to pass to the procedure.

Example:

'Call a Sub procedure
Call Addition(5 , 4)
 
Sub Addition( num1,num2)
Result=num1+num2
Msgbox  "the Sum of the numbers is    "  &  Result
 
End Sub

⇒Function Library & Associating Function library to a Test
Different Types of Library files
Different types of library files are ".qfl" files,".Vbs" files
Steps to follow to create Function Library:
1. Functions are created manually:
   File-->New-->Function library(Enter the functions)
2. Save the functions:
   File--> Save (File is saved as .qfl file)
3. Associating Function library to a Test:
   Test --> Settings --> Choose Resources tab --> Choose + button so select the ".qfl" file --> browse and select the ".qfl" file -->
   click OK.

How to use library files in QTP & how we can call these files in to script?

We can load the external Library files by using 2 ways:
1. Choose Test --> Settings --> Choose Resources tab --> Choose + button so select the library file --> browse and select the
   library file --> click OK.
2. We can load the library files using Scripting:
Use execute file function to load library files:

Step1. Open a notepad and paste the below function
Example:

'Code in External Library file(sample.vbs file).
 
function SumOfTwoNumbers(a,b)
Dim sum
sum=a+b
SumOfTwoNumbers=sum
End Function

Step2. Save the notepad as a .vbs file(sample.vbs) in path "D:\Sample.vbs"
Step3. Paste the below code in QTP and execute,You will find that the below code access function from the "sample.vbs" file
Example:

executefile "D:\Sample.vbs"
x=10
y=5
result=SumOfTwoNumbers(x,y)
msgbox result

Example 1
function library------------------------------------------------------------------------------
Public Function Open_browser(ByVal URL)
Set obj=createobject("InternetExplorer.application")
obj.visible=true
obj.navigate(URL)

       ' TODO: add function body here
End Function

Test-------------------------------------------------------------------------------------------
Open_browser("www.gmail.com")

Example-2
function library------------------------------------------------------------------------------
Public Function VerifyProperty(ByVal Test_obj, ByVal Actual_value, ByVal Expectedvalue)
    Dim var
    var=Test_obj.GetROProperty(Actual_value)
    If var=Expectedvalue Then
       msgbox "Expected value equals to actual value"
       else
       msgbox "Expected value not equals to actual value"

    End If
End Function
RegisterUserFunc "WinEdit","Verify","VerifyProperty"

Test-------------------------------------------------------------------------------------------
'
'Window("Window").Window("Start Menu").WinButton("All Programs").Click
SystemUtil.Run "C:\Program Files\HP\QuickTest Professional\samples\flight\app\flight4a.exe","","C:\Program Files\HP\QuickTest Professional\samples\flight\app\","open"
Dialog("Login").WinEdit("Agent Name:").Verify "attached text","Agent Name:"
Dialog("Login_2").WinButton("Cancel").Click
