>When using SQLStringConnect(), I need to set the timeout to 2 seconds. Presently, that is around 10-15 seconds and that is extremely too long for the need we will use it in. Basically, when the connection is good, we have it right away. So, after two seconds, if it doesn't work, I need to stop the process. Any way to achieve that?

Try

SQLSETPROP(0, "ConnectTimeOut", 2)
