One UDL Connection String for multiple forms

Thanks for replying RyanDev.I have a .udl file which I am using to connect to a database on sql server 2008.But the thing is on click of submit button say on Form 1 or Form 2 a new connection is established to the database ie multiple connections via Form 1 and Form 2 because I am writing OleDbConnection conn = new OleDbConnection("File Name=E:\\Vivek\\License Manager\\License Manager\\login.udl"); on button click of both Form 1 and Form 2.So how to use only one common connection string that an entire application can use ?

I hope my doubt is clear
