date/time comparsion with sql locale setting problem

I am writing an application with vb6 and access 97

I pass query which will compare the database's date/time with the current date/time. eg:

SELECT  (CAExpiry - #" & Now & "#)  AS ToBeExpired, FROM CompanySearch

But my users will use different language and have different locale setting for date/time

So, some users have error with the query

I would like to ask what is the safest way to make sure different setting of locale can use my program?

Thanks

The best way is to use dateserial:

Dim myDate As Date
myDate = DateSerial(Year(Now), Month(Now), Day(Now))

Or, if you want to make sure it is US format:

myDate = Format(Now(), "mm/dd/yyyy")

Or European format:

myDate = Format(Now(), "dd/mm/yyyy")

My Access file has specified date/time format: dd/mm/yyyy hh:nn:ss

Does it matter?

Do I have to consider the date/time format of the Access file?

Or, as soon as I specify myDate = Format(Now(), "dd/mm/yyyy")

I can use myDate to compare with the date/time of the Access file?

Access dates are always in US format. See MSDN:

..."When you specify the criteria argument, date literals must be in U.S. format, even if you're not using the U.S. version of the Microsoft Jet database engine. For example, May 10, 1996, is written 10/5/96 in the United Kingdom and 5/10/96 in the United States. Be sure to enclose your date literals with the number sign (#) as shown in the following examples.

To find records dated May 10, 1996 in a United Kingdom database, you must use the following SQL statement:

SELECT *
FROM Orders
WHERE ShippedDate = #5/10/96#;             ..."

Therefore you must  force a US format on the user's entry.

ps. which means to replace the user's European entry with the US format as above.
