All,

I have a byte[] array that I save as a file to disk, is there anyway of
saving the file as a transaction. For example I save the file to disk and
virus scan it, if no virus is found I commit the transaction, if a virus is
found I abort the transaction and the file is never written. Is this
possible to do with COM+ if not can someone suggest an alternative method.

Thanks
Msuk
 
One thing to note is that COM+ transactions require that the participating
systems also be transaction aware. So in your case you would need a FS and
an AV software that was transaction enabled. IMHO COM+ will not work in this
situation, you would be better off writing your own transaction code.
 
It is possible to write your own compensating resource manager that will
work with COM+ transactions, but it is a pain, and I wouldn't recommend it.

Not that this is any comfort, but Longhorn will offer a transactional
filesystem. There was a great demo of NTFS transactions during Tech Ed (and
I'm not talking about Win FS either).
