Well, because of using sql client you can not use the oledb provider
try using this connection string :

workstation id=your_computer_name;packet size=4096;user id=v-tleung;data
source=your_sql_server;persist security info=False;initial catalog=Pubs;
Password=Mynameis@01;

if your sql server is installed locally for data source put : localhost

you can see here all of possible connection strings :
http://www.connectionstrings.com/
