Some OLE DB providers can check the current state of the connection. For example, if the database server has recycled since you opened your OleDbConnection, the State property will continue to return Open. If you are working with an OLE DB Provider that supports polling for this information on a live connection, calling the method and then checking the State property will tell you that the connection is no longer open. The method relies on functionality in the OLE DB Provider to verify the current state of the connection. To determine if your OLE DB Provider supports this functionality, check the provider's documentation for information on DBPROP_CONNECTIONSTATUS.
