[AccessD] CheckDate?

Hi Borge

Well, the problem is that IsDate() and CDate() don't care for "likely
dates" only possible dates which date strings formatted as yy/mm/dd
certainly are.
If you need dates within a certain time frame, you'll have to check
that on your own as you already have done.

You could also, in the BeforeUpdate event, check for 

  Day(strDate) = Val(strDate)

or, for our US formatted friends:

  Month(strDate) = Val(strDate)

Hi, amazing how inexhaustible this subject is....

I have an unbound textcontrol formatted dd mmm yyyy or dd mmm yy

If I enter 32 Dec 2004 Access will cut in and tell me: Not a valid
entry
etc....

If I enter 32 Dec 04 - Access interprets as 4 Dec 1932

When I test for a valid date in the beforeupdate event using IsDate()
it
tests on the 4 Dec 1932 value ....

What am I doing wrong here?

Or rather : how do I catch obvious incorrect entries like 32 Dec 04
using
IsDate() before Access let them slip through?

Currently I test entry in text control box on the validation rule
property:
>=#1/01/2001#
Hmmmm....

Regards
Borge
