I have a visual basic 6 that relies on internet connectivity. We use it to time races (5k, marathon, triathlon, etc). I use the following connection string to my server:
srvr_conn.Open "Provider=SQLNCLI10;Server=216.185.199.1,1433\SQLExpress;Database=db;Uid=uid;Pwd=pwd;"
How long will this connection stay open? Is that a server setting?
