i use the mysql components with the unidirect components in a server program. when the connection is not used over the interactive timeout and then used again i get this exception.
in my code i call connection.open() before and connection.Close() after the db access.

does anyone know this problem?

thx

Use Ping() method and recreate connection if necessary.

I use UniDirect i dont know if the connection is an mysql or mssql or whatever.

the unidirect connection doesnt have an ping method.

i think the cleaner way would be that this ping method is called in the open method of the Mysql provider.

Which version of MySQLDirect version do you use?
Do you have this problem when you use native MySqlDirect .NET MySqlConnection component instead of UniConnection?

I use version 2.50 of the mysqldirect components.
I dont know whether the problem exists when using mysql direct.

Please download latest version of MySQLDirect .NET.
