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

The Connection String Which We Are Assigning from server side will be same as that From Web config File  The Catalog  Means To  Database it is followed by Username and Password And DataClient The New sql connection establishes The connection to sql server by using the credentials in the connection string   Then it is followed by sql command which retrives the required data in the dataset and then we assing them to required variables or controls to get the required task done
