Would love to see a sample app on this one. I've got a large app and am
getting to the point of needing to break it up into modules.

What I usually do, is pass the TIB_Connection.dbHandle property to the
DLL and assign it to the TIB_Connection.dbHandleShared property in the
DLL. And, you don't have to call Connect and Disconnect, since you are
already using an existing connection handle.

If the DLL is dynamically loaded and unloaded within the context of the
thread,
then I don't see any problems. Otherwise, there would most likely be
problems.
