Thanks Geoff and Roger for your answers; I am able to use the
connection now, but I'm still having problems when calling
FreeLibrary(MyDllHandle). I don't know what else to do, the flow I'm
using is something like:
EXE: On Create logs in the DB and loads DLL
EXE: Button that calls DLL procedure passes the dbHandle
DLL: Creates MyForm that contains a TIBODatabase, and assigns its
dbHandleShared := EXEConnectiondbHandle
DLL: Shows the form, etc... user Closes the form
EXE: IBODatabase.Close
EXE: FreeLibrary
DLL: case DLL_PROCESS_DETACH: DLLDatabase.dbHandleShared := nil
DLL: MyForm.Release
and then it crashes; as far as my trace could go this happened after
the IB_Session unit finalization, but I'm not sure about what caused
the error.

Is something missing???

TIA
Eduardo
