This was a known error with IB 5.5 and 5.6. If you use one that change your
gds32.dll to 5.1.

With IB 6.0, there is no problem noted untill now.

Subject: [IBO] TIB_Event Alerter Problem and Application Exit


> Hello,
>
> I am experiencing a strange problem with the TIB_Event control for
Interbase. I'm building an application using Borland C++ Builder 5.0 and
IBO components to access an IB Server 6.0. I'm using an Event Alerter to be
aware of the modifications made by other users, so that I can refresh a view
screen that outputs data on a grid. My application actually register's the
TIB_Event control successfully and the OnEventAlert executes correctly when
the event is posted on the server using POST_EVENT "eventname" from within a
TRIGGER or STORED PROCEDURE. But whenever I close my application I get an
error:

and the TIB_Event control points to this connection via the IB_Connection
property.
