Wants Help to Create DLL file Creation

Dear All,

Could you please help me, how to create DLL files for a database project. In this project, i want to connect database to all forms, but now i am creating separate connections to each form. Instead this, i want to connect once to database and applies to all forms.

Thanks in Advance

There have been some disussions here about 3-tier and n-tier development. One thing is for sure it is not an easy question and will take up alot of your time.
