Divesh, I'm not sure if you ever come back and see my reply, but I'll post it nontheless:
When reading the help about "obj_get_desc", have you pressed the "Example" button in the help? It shows you an example how to use this functions and how the parameters could look like.
Another way to find out more about this is the menu "Tools > Gui Map Configuration" and the corresponding chapter in the User's Guide.
PS: The moderator was not unpolite, Tony just wanted to know your amount of knowledge and investigation about this topic, so that we can find out how much expertise we can assume when answering your question.
Divesh124, my intention to post was exacly as bru has stated. Wihtout understanding your level of knowledge on the tool (as you had only one post prior to the question), I was intended to elicit what steps you had done to learn out the tool. It was not meant as a slap in the face, and a question that has been asked of me numerous times when i start posting in a new group - one that is expected to be asked by me from those I havne't dealt with in the past.
Apologies for it offending you, but on a side note if that set you off then are you sure QA is the right profession for you? A thicker skin that that is needed when dealing with what QA is about.
