Restoring Transaction Logs Into Backups of MDF and LDF

Hello,
Here's a brief outline of my scenario:
I am trying to recover from a database corruption problem. I have a
backup of the db's physical MDF and LDF files from before the
corruption, but no actual backup (ie bak file). I also have daily
transaction log backups right up to today, and my live db is still
operation despite the corruption, so I can take another transaction
log backup when I do the repair.
The problem I have is I don't know how to, or if it's possible to
attach the backup MDF & LDF files and then somehow apply my
transaction log backups to build a new up to date database.
Thanks,
AlexYou would need Attach with NORECOVERY, which currently is not a possibility.
There is a connect item you can vote in for a future feature request.

If you don't mind my asking, what kind of corruption did you get and how did
it happen. We're just moving to SQLServer to avoid corruptions and I'd hate
to find that we did not leave the problem behind.
