Dear friend, Thanks for replying. Plz note and try to understand. Suppose any software prepaired by us and I distribute to any one telling him for not to give any other person for use.

Thanks for your suggestion I have used app.config file to store connection string for rest of my application but i am unable to create cyrstal report using that string. Because when I create crystal report i need to use database field from field explorer which are present only when i establish connection at creation time of crystal report. Is there any other way to generate crystal report so that i can use app.config connection string for that.

when i create crystal report the database is at some location. but when i prepare setup of that windows application and deploy it on some other system then the path of database change and the crystal report does not load the correct database. Please help.. Thanks in advance.

Thank you so much . It works as per you advice.
