Again...problems with date settings in IsDate function

Hi All,

I use IsDate() to check a field in Outlook tasks to see if it contains
a real date.
If IsDate(Task.role) then
...
else
...
endif

On my machine at home I get an error when the role field says:

03 Oct,

And at work I get an error when the role field says:

03 Okt.

Because at home I use Dutch as regional Settings and at work English
US.

Is there a way to go around this problem, so it doesn't matter what
regional settings I have?

Regards
