The short answer is that VB doesn't support 64 bit integers.
You could probably come up with a way to represent them using a Byte or Long
array. For some tasks, using the Decimal data type of a variant might work.
It depends on what you need to do with that int64.

If you are passing by reference pass the first long of a long array of two
elements eg
dim l(1 to 2) as long
call someroutine(l(1))
BUT don't forget the number will come back reversed
so if you had a value 1 in the 64 bit number hex H00000000 00000001
it will come back as
l(1) = H00000001
l(2) = H00000000 !!!!!!!
BTW if you are J of A does it mean us English have got to burn you again - is
that what you understand by a flame? :-)

But it has a 64bits type: Currency.

Thanks for the technique.
I'm trying to handle file times, to be more specific.

Hi Jonathan --
>Currency is not an integer type.
Close enough. It's a "scaled integer" and works fine for the original question.

Hi John --

Here's what I use:
Private Type FILETIME
dwLowDateTime As Long
dwHighDateTime As Long
End Type
You can see a complete example at http://www.mvps.org/vb -- FileInfo.zip on the
Samples page.
