Thanks, but this is not working.
Let me explain want I want to do.
I have a bunch of files from differents folders that I want to copy.
But, before copying thoses files, I want to check if anyone of theses file is in use.
So this way, I can copy all the files.
If I don't check, only the file that where not in use would be copyied...
Basically, it's like a transaction and if an error occurs, I want to roll back the transaction.
And, even if the file is open, I can still "re-open it" from VB.
So, does anybody know a function, API, or way to check if a file is in
use.
