by giving the duration how can i get the date?

Gotto agree with you Suthish....He not only answers fast but answers correctly too :-).....I don't treat this as a competition (even so I am honored to lose to a worthy opponent).....I am pretty sure Vulpes will agree with me that we are all here to help one another and share our knowledge.

@Vulpes: Totally agree with you :-)

This was a simpler question to answer than your last one but certainly wasn't a silly one.

Although it's not the ideal place to learn anything, you might get some benefit from reading the MSDN docs on the DateTime (http://msdn.microsoft.com/en-us/library/system.datetime.aspx) and TimeSpan (http://msdn.microsoft.com/en-us/library/system.timespan.aspx) structures. You'll then be able to compete with Raja and myself to answer these questions first :)

Thank you both....You are doing a great job...
