1) i have opend 2 gmails i am working with 1 gmail i want 
to close other gmail by usig script.
Ans: Use index property to uniquely indentify the Browser. 
In QTP, for any object, Index starts from Zero. If only one 
browser opened, Index value is Zero. For the second 
browser, index value will be 1 and so on.
The below code will close the second Gmail brower if it two 
or more Gmail Pages are opened. Otherwise It won't close.
If (Browser("title:=Gmail: Email from 
Google","index:=1").Exist) Then
	Browser("index:=1").Close	
End If
If u want to close any broswer, use only index property in 
Browser object




2) i have 10 links in a page all of them have same 
properties& names i want to click on 5link by using script.
Ans: Use index property in descriptive programming so that 
u can perform click action on 5th link.
i.e 
For example, ABCD is the name of the link and page contains 
10 links with the same name ABCD and you want to click on 
5th, this case the below code work. Index starts from Zero. 
So fifth link contains the index value 4.

Browser("title:=Gmail: Email from Google").Page
("name:=Gmail: Email from Google").Link
("name:=ABCD", "index:=4").Click

excel sheet into Local sheet
Step2: Get the rowcount of two Globalsheet and localsheet
