I'm using an Access 2000 (ADP) project, and I'm trying to create a global error handler without having to to do the following in each Sub and Function:
On Error GoTo Error_Handler_1
'Code here
:Exit_1
exit sub
:Error_Handler_1
Call Handle_Error
Goto Exit_1
Public Sub Handle_Error()
msgbox "An error has just occured"
end Sub
Anybody know how to do this?
If memory serves me here, the main sub's errorhandler stays in effect for all subs called from the main sub.
If you write your app as subs called from the main then you only need one error handler.
I'm sure lots of people will correct me if I have not understood the concept and this is not the case.
Hi Wool1,
I haven't used Access 2000 but since it's all based on VB,
I believe you are out of luck here.
You can write a global error handler but to do it properly
reaches into the realms of rocket science--and you still
don't get away from On Error Goto's in ALL :mad: your Subs
and Functions.
Maybe someone else knows a way, but I wager you'll have
to wait for VB7 (or VB.Net) for some better way of doing
it.
HeSaidJoe says to keep it simple and write your app as
sub's called from Main(). If your routine get's anything
near level 1 complexity on a scale of 1 to 10, you start
losing track of which routine caused which error and where
to resume back to. A global error routine in Main() is Ok
if all you ever want to do is abandon the routine that
caused the error and report it, but if you want to recover
gracefully and resume the routine that caused the error
(let's say the routine is 10 calls deep), it starts getting
very messy indeed.

Quite agree with that, I was just stating how it would work if my memory served me correctly, and I wasn't even sure of that till I tested it afterward.
The level of complexity (depending on what you are doing with the application), could be simple or so severe it isn't worth the time to even think about it.
:D
No offence meant HeSaidJoe, and I think your memory serves you very well indeed... :oQuote:
