VB.Net connection timeout expired

[daniel50096230]

The following is my connectionstring:

server=(local);database=JnJ3;uid=sa;pwd=sa

May I know how can I avoid timeout expired because I keep on receiving error message when deal with huge amount of data.
The timeout period elapsed prior to completion of the operation or the server is not responding.

You set the timeout on your commands you run towards the database and not the connection string.
