Subject TIB_Event Alerter Problem and Application Exit
Author Chris Hulsey

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:

I am connecting with a TIB_Database control to a remote server via TCPIP and the TIB_Event control points to this connection via the IB_Connection property.

"Fault with Message Access Violation at address XXXXX read of address XXXXX process stopped."

My Code is Simple:

TIB_Database *IBDatabase;
TIB_Events *IBEvent;
TPanel * Panel_Event;

void __fastcall TForm1::IBEventEventAlert(TObject *Sender,
AnsiString AEventName, int AEventCount)
Panel_Event->Caption = "Event Fired: " + AEventName;

void __fastcall TForm1::Button1Click(TObject *Sender)
Panel_Event->Caption = "Registered";

void __fastcall TForm1::Button2Click(TObject *Sender)
Panel_Event->Caption = "Unregistered";

Any help would be greatly appreciated.
