Description object is Used to create a Properties collection object in QTP.

Description object has one method  - Create 

It returns a properties collection object in which you can add a set of properties and values in order to specify the description of an object.We can add any number of properties to define the description object in QTP

Syntax

set Myobject = Description.Create

Example

Below example uses the Create method to return a Properties collection object named Myobject  

set Myobject = Description.Create()

Myobject ("Name").Value = "userName"

Myobject ("Index").Value = "1"

Browser("Myb").Page("myp").WebEdit(Myobject ).Set "sagar"

Another Example - 

In below example we are finding the all links from the page whose innertext property is in digits.

Please note that value of the property is considered as regular expression by default . But if you don't want to  treat the value as regular expression, Then set it to False like this 

 '  objLinkDash("innertext").RegularExpression =False

        Set objLinkDash = Description.Create
        objLinkDash("micclass").Value = "Link"
        objLinkDash("innertext").Value = "\d*"
        objLinkDash("innertext").RegularExpression = True

       ' By Default it is considered as regular expression

         cnt = constobjParent.childobjects(objLinkDash).count
         Set childs =  constobjParent.childobjects(objLinkDash)

Description object is used to create objects whose properties are changing at run time.
