Update a Database from a Dataset

Hey,
Does anybody know how to Update a Database from a Dataset? I keep on erroring out at "drCurrent = tblParty.Rows.Find(Me.txtPartyID.Text)" within the Button1_Click. The error messages says "Table does not have a primary key." Is there any way around this besides adding a primery key?

MY GOAL IS.....to be able to hit a SQL Server Database, pass a few parameters to a stored procedure, get the dataset, update, the dataset & FINALLY update the database with the dataset!!!

If someone could help me out...I would be the happiest man alive! ;) Thanks again.

Code:
