Is there a way for Access to read CRC from other files?

P: n/a
Hi everyone

I have a database containing pictures (actually only links to them). Each
picture has a ID consisting of a number.

My problem is this: as more pictures are added, duplicates will occure. I
want to use the CRC for each
image-file as its unique identifier, thus reducing the risk of duplicates.
There are a lot of standalone CRC calculators but I wonder if there is any
way to have Access read the CRC?

Any help is much appreciated
Dwight

There's nothing built into Access, but it's not that hard to find algorithms
that calculate CRCs.

I just looked in Google (for +CRC +VB), and the following looks promising:
