Descriptive programming means we can write VB Script 
without objective Repository.  we can write program with 
the help of object properties.

ex:  if u want to write descriptive program for login page

login page have userid and password and ok, cancel button

every object have some common properties with that we can 
write descriptive program suppose u take here login is 
window.

 Window have some properties like TEXT, ATTACHED TEXT, 
NATIVE CLASS, WINDOW ID.....


same as for Text boxes having TEXT, ATTACHED TEXT, NATIVE 
CLASS, WINDOW ID....

with the help of above properties we can write descriptive 
program

In Three Situations we go for Descriptive Coding
a)When QTP is unable to identify the "Object" in            
the Application?
b)When the "Object repository" become large to avoid that
c)When we are writing "Script" the application is not 
ready, then we go for "Descriptive coding". For that dev 
team provide LLD Docs.

Each object has default properties like Text Box has Text, 
Attached Text, Native Class, Window ID.


Ex:- for login window

Dialog("Name:=Login").Winedit("Name:=User 
Name :").set "Abcedf"


Dialog("Name:=Login").Winedit
("Name:=Password :").setsecure "Mercury"


Dialog("Name:=Login").Winbutton("Name:=Ok").Click


That means we provide the properties in scripting for 
identify the objects in application.

the Two above answers are correct...

      there is simple technique to write descriptive
programming..to write DP we use Object Identification dialog
box and Object spy dialog box.

Object Identification dialog boxes uses to know which
properties can identify an object uniquely and Object spy
uses to know values of this property..this technique is
suggested when the application is ready only. If application
is not ready we can write only visible properties, like
text, attachedtext, class.

  we can write DP in two ways..by throwing the properties
and their values directly in to script (or) by creating an
object by using description.create method.

for example:

set objtext = description.create
 objtext("nativeclass").value = "Edit"
 objtext("attachedtext").value = "XXXXX"

   this will create a text box object.

 browser("sadgd").page("sahdga").webedit(objtext).set "asgfsad"

second method is:

  
browser("sadgd").page("sahdga").webedit("nativeclass:=Edit","attachedtext:=XXXX").set
"asgfsad"

How do I record a script to automate the username and 
password for 3 different types of surveys who's username 
and password are all the same? I need to run this same 
piece of script against all these surveys who get prompted 
for the username and password at the exact same place.
