Try  Dim connectionString AS String    Server my server Database name of db User Id user name Password my password    And replace my server  name of db  user name and my password with your values   then Using sqlCon   New SqlConnection connectionString  should work  also I think your SQL is wrong  it should be SET clickCount  clickCount   1 I think   And on a general note  the page you link to has a link called Connection String which shows you how to do this
