    Dim MySQL as string = "Insert into user_data (user_id,[timestamp],non_availability,cause_of_non_availability) values (@ppid,@tst,@noava,@cnoava)"
    Dim myConn As SqlConnection = New SqlConnection("data source=tstsrv;uid=;pwd=;database=user")
    Dim Cmd as New SQLCommand(MySQL, MyConn)
    cmd.Parameters.Add(New SQLParameter("@ppid", pumpi.text))
    cmd.Parameters.Add(New SQLParameter("@tst", tmstm.text))
    cmd.Parameters.Add(New SQLParameter("@noava", navl.text))
    cmd.Parameters.Add(New SQLParameter("@cnoava", cnaval.text))

     MyConn.Open()
