Ensuring numeric input

[Lynch, Jonathan]

It's a matter of interpretation...

My date interpretation will automatically complete a date.

11/9 becomes 11/09/05 (this year, next year it will be 11/09/06.

1/2 becomes 1/02/05


12/0w/05 would be automatically converted to 12/01/05...
2005/0w/14 would be converted to 12/01/2014...
This last one is because the American convention is Mo/Day/Year, and the
program is not set up for the year/mo/day convention (although it could
be, if that were ever an issue).

It can't be perfect, some things just cannot be interpreted.  In my
situation, I cannot afford to have an invalid date in a date field, or
it will cause a cascading list of problems - so I have to be rigid about
that. But I see what you mean, if possible, it would be better to be
nice to your user and allow them to correct an invalid date rather than
have to type it over.

That sounds like a good approach, *except* (for someone as poor a typist

as me)

 - I type 2005/0w/14     (i.e. mis-hit the 'w' below the '2' that I was 
aiming for)
 - hit return (or tab or ...)
 - and because it's not a valid date, the whole lot goes and I need to 
start typing from scratch ??

Some days, I'd never complete typing a date ! :-)
Hopefully, you allow some way to get back the invalid typing so I can 
just edit that.
