Get & send email with attachment from sql view address field within VB.Net 2010

Hello,
I have a simple email program from vb.net 2010 the program works successfully. Within the code I want to change part of a code - mail.To.Add("JohnDoe@hills.com") , which is hard coded and get vb to get the various email address from a sql server view (2005) called vlv_customers the view contains, a field call EmailAddrAddress, EmailAddress2, EmailAddress3 (there are multiply fields containing email address). I already have a DataSet call - 500_appDataSet1 containing the email address fields. How can I get vb.net to read from the view the various email address fields (some fields maybe Null - not having any address at all ) and send out the email with the attachment to single or multiple email address. I would really appreciate to get advice from someone who had this experience. I am not using ASP, just vb.net Form. Please take in consideration that I am new to VB.Net. Thank you in advance.
