ConnectionTimeout Property (ADO)
Indicates how long to wait while establishing a connection before terminating the attempt and generating an error.
Settings and Return Values
Sets or returns a Long value that indicates, in seconds, how long to wait for the connection to open. Default is 15.
Use the ConnectionTimeout property on a Connection object if delays from network traffic or heavy server use make it necessary to abandon a connection attempt. If the time from the ConnectionTimeout property setting elapses prior to the opening of the connection, an error occurs and ADO cancels the attempt. If you set the property to zero, ADO will wait indefinitely until the connection is opened. Make sure the provider to which you are writing code supports the ConnectionTimeout functionality.
The ConnectionTimeout property is read/write when the connection is closed and read-only when it is open.
