5)DTParameter Object
6)DTSheet Object
7)Environment Object

Lets discuss some of them :

1) Crypt Object

Browser(“Google”).Page(“Google”).WebEdit(W_Edit).Set “Mindfire”

4)DotNetFactory

5)DTParameter Object
——————

>DTSheet.AddParameter
>DTSheet.GetParameter

Ex:Show_Param=DataTable.LocalSheet.AddParameter(“UserName”,”Mindfire”) ‘This will show the newly created parameter in the run-time Data Table ‘
msgbox Show_Param

6)DTSheet Object
————–
It is a Sheet which can be accessed during run time by following methods or properties:
>DataTable.AddSheet

     Msgbox Show_Param

7)Environment Object

QTP Environment variables are special type of variables whose values persist across and are shared by all actions
in a test.QTP environment variables can be used to share information across actions,recovery scenarios and libraries.

  My_Var=Environment.Value(“My_Var”)
