I've upgraded my SQL Server 2005 to 2008, without backing up the databases. I kept the old data folder with the 2 `DB.mdf` and `DB.ldf` files. 

So how can I import or read my `.mdf` file into SQL Server 2008 ?

If I try to use the 2008 tools import/export, I am unable to find the source because the 2005 has been replaced. Only the server 2008 is running.

If not possible, An other way, would be to read the `.mdf` file with vb if you know

Thank you for your help

regards
Mike
