Thanks Jason

Each thread has its own IB_Connection so I suppose that means I will have a unique handle for each dll call. However I have discovered that the Dll is dynamically created outside of the thread so I will have to look at restructuring my code (bummer!).

p.s. you may reacall I was having Thread crashes on some machines last week. It took me a week but it turned out to be an old BDE API call in some inherited code ! The application would work fine on most machines because they had all had the BDE installed for our old DBase code. It took me days to find, perhaps I need more faith in IBO / Firebird :)

Just make sure you don't have different threads acting upon the same
connection handle at a time. To my knowledge the connection handle has not
been made thread safe, and even if they did, it would probably be just to
serialize access anyway, which defeats the benefit of allowing multiple
threads to access it simultaneously.

Someone please correct me if I'm wrong, as it certainly could be possible
for the connection handle to allow asynchroneous access to it at some point.
