How can I use Childobjects in QTP for Identification of WebElements

Set obj =Browser().Page().Childobjects(odesc)
Set obj_number = obj.count this count represents the number of objects that are satisfying the description that you have made using description.create().

obj is a collection object of all such objects... you can imagine it like an handler.
you can use the below code for performing action on the first object in the collection

obj(0).click This statement will perform click method on the object.

Please note that the collection index starts from 0 zero.

Hope this answers your question.
