TransactionScope question

Hi,

I'm building an application that performs some operations of several kinds :
file copy, IIS web site creation, etc...

Since if one of this operation fails, all others have to be rollbacked, I
started to look at the transactionscope class and IEnlistmentNotification
interface.

How can I know what objects in .Net framework implements such objects ? I
know ADO..net does, but what about DirectoryEntry, File.Copy, etc ?

I implemented manually the File.Copy to support transaction... but what a
pain ! Is there any namespace or class that can do the job for me ?

Thanks in advance,
Steve
 
Hello Steve B.,

I suppose your transacted file copy code looks like this one http://codebetter.com/blogs/sahil.malik/archive/2005/04/28/62604.aspx
:)

The problem u are stublem is an issue in the modern development, because
there are no Resources Managers for the such things like file copy end etc.
The solution for this is the STM - software transacted memory, where we can
operate the set of memory block, like files or arrays, within transations

unfortunatelly there is no standart implementations yet

I suggest u to read this http://weblogs.asp.net/ralfw/archiv...onal-memory-making-multithreading-easier.aspx
to understand the deep of the problem :)

Mine works with File.Copy, but the idea is the same.
I found tha Vista use KTM for making disk and registry changes
rollbackable... but as my apps runs on W2K3, I can't rely on it (or will it
be available for wxp ?)



Thanks for the link, it seems to be a usefull reading.
 
Hello Steve B.,

Vista KTM is probably the part of the WinFS, what they did is just provide
the resource managers and/or compesators for this, imho

I don't thing that u need rely on KTM, just read the link I gave u and try
to used the 3rd party STM realization or I'd think about implementing compensators,
like we do in COM+ providing the rollback for non-transactable components
