vbscript to leverage transactions (and rollbacks) in Vista file

Hey all. Vista has hooks built into it to support transaction enabled
NTFS. That means theoretically you can start a transaction scope, do
stuff and then commit or rollback? Catch is Microsoft didnt include
the transaction management commands that where built into the early
release candidates...but they did leave the hooks for code to use the
functionality. I have seen this demonstrated in C sharp, but I would
like to use the functionality in vbscript if possible.

Anyone know anything or have an exmaple? Its cool stuff and I am
surprised theres not a lot of chit chat regarding this.

That does sound interesting but I've not heard of it. When you say
transaction scope you mean like doing system commits or restore points
unattended, something like that?

Look at Scriptomatic or WMI, or maybe even powershell, since that
seems to be the scripting direction. They might have something like
that capability. If you do find something cool, let us know!

Hey sumGirl, I am assuming you are referring to "Introduction to
Vista Transactional NTFS (TxF) with Detours", by Tamer Safwat Aziz,
found here:

http://www.codeproject.com/KB/vista/Transactional_NTFS.aspx

and including "Detours 2.1" found here:

http://research.microsoft.com/sn/detours/

I don't know anything about c-sharp (or c++ for that matter)
but the code on Aziz's page looked more like c++ to me.
Regardless, the code was all system api's, and so could be
coded in any language supporting api calls, including vb.

While there is no pre-packaged utility, there is (as you said)
demo code. If it's c#, then you could use microsoft's
"interoperability" (or interop for short) capability to wrap
it into something usable from vbScript. If it is c++, then
you just need to wrap-it-up in a "dual interface" wrapper
(IUnk & IDisp). Or, if you are fluent in converting C to vb,
(also a language suitable for calling the system api), then
you could make a vb actX object callable from script.

While it may sound harsh to suggest a do-it-yurself approach,
if you want it bad enough, that is one way to get it.

cheers, jw
