Nice, but I assume this is a function that you manually call in your own code, instead of the regular DbConnection.BeginTransaction? The problem is that the framework I'm using does it all under the hood: opens connection, starts and ends transactions and executes SQL. I add the DbConnection component I need to my form, in my case an FbConnection, and configure my framework's persistence handler to use that connection. The persistence handler has a lot of settings for the SQL connection, but for fetch and write transaction mode it uses the standard System.Data.IsolationLevel enum type, so there's no way to configure FireBird specific transaction options. What I need is some way to hook into the FbConnection's call to start a transaction, or "globally" configure it to a specific transaction option/mode/isolation level, either overriding the System.Data.IsolationLevel that the framework's persitence handler passes in, or map it in a different way than apparently is standard for the Firebird .Net provider. I.e. map ReadCommitted to ReadCommitted + RecVersion + NoWait rather than ReadCommitted + NoRecVersion + NoWait. Possible? Inherit from FbCOnnection and override BeginTransaction and use that (derived) component in place of FbConnection?
