I have done a little more research in this and the code is fine till I reach
the end of the procedure Im executing
procedure TForm1.F1Book1ObjValueChanged(Sender: TObject;
var ObjName: WideString; ObjID: Integer);
var
..
begin
..
end;{TForm1.F1Book1ObjValueChanged} *****************>this is the line that
when it executes causes the application error
now this code worked yesterday, and I didnt change anything overnight it
just stopped working, that is why Im at a little bit of a loss.
I havent tried rebooting yet, just restarting delphi, the reboot happens now
to see if that fixes the problem, and if not then a delphi reinstall....
Thanks for the advice tho Conor
