Many thanks to you both.
Had thought in my op that there was some function or udf that I had been
unable to find/google search to do this.
But it looks as though 'IsDate/DateValue' may well do most of what I need.
Thanks again.

Regards.

But just to add, isdate and datevalue appear to be more discerning
although
lightly tested:

? isdate("02/30/05")
False

? datevalue("02/30/05")
raised a type mismatch error.

Unfortunately, Excel isn't bothered by 30 Feb 2005

? day(dateserial(2005,2,30))
2

So I guess you would have to write the validating code. Or, why not use
a
combobox. Use a single combobox if a reasonable range of dates or use 3
comboboxes that are progressively restrictive based on the preceding
entry.
Entry should be Year, Month, Day. Or possibly use your current setup,
but
still make the choices progressive. (I haven't really given that one
much
thought, but it is probably easier than checking everything).

It is doing that Stuart

Day(DateSerial(Me.text1, Me.text2, Me.text3))
For example if you fill in 2005,2,30 in the textboxes

MsgBox Day(DateSerial(2005, 2, 30))
will give you day number 2

So if you test if the day number in the textbox is the same then you
know
you have a valid date

Many thanks, but I may not have explained correctly.

I wish to let the user specify a date (any date of their choice) but
then check it's validity against (eg):
it cannot be 30th February
it cannot be 32nd December
it cannot be 0th any Month
etc

Hope this is clearer.

Regards.

Hi

You can test the day number is the same in the textbox and in the
date
you create with the
three textboxes

Use
If Day(DateSerial(Me.text1, Me.text2, Me.text3)) =daytextbox then

How do I get a date from a user, via a form, and then validate
their
entry, please?

I currently have textboxes and labels as follows:

.......... / ........... /
................
tbDay Lb tbMonth Lb tbYear

where "16/05/2005" would be validated, but
"30/02/2005" (for example) should not be validated........
don't remember 30 days in February anytime recently.

Surely there is an easier way than having to write all the
validating
code?
