"Invalid handle to the function"

[Database Administrator]

Greetings all,

I'm sort of posting this for my own future reference, but hopefully it'll
help others.

I was testing my app using Australian dates, instead of US dates. When opening
a form, I got a message 'invalid handle to function' with no further explanation.
After checking all of my code, I couldn't figure this out.

The problem was that I had used SetRange() on the form's master table for
a given date range, then saved the form. This was stored in US date format
(ie 12/24/2007). When Pdox tried to open the form, it didn't know how to
handle this date in Aussie format (no month 24).

HTH,
Jim Moseley
