New That was a joke
That was a joke, not a programming idea. On Error Resume Next tells VB to simply continue with the next step when there is an error. This causes all sorts of havok when there is a real problem.

But if you want a really global error trap, then either put the entire program inside a try/catch block or a global On Error statement at the start.

There isn't much you can do in VB if you catch errors at that level though. All you can do is present some formatted error information and quit.

New For certain techniques, it works.
Specifically, the practice of manually checking ErrCode after steps that could catastrophically fail. It's a bit lazy, though for some types of code, the risk of an uncaught error is suitably low.

Somebody save my life
