New Post: Store media in MS SQL database

Sorry all my msgs!

Last: The provider is almost working. I can add and delete folders and files. The only thing i couldn't resolve is de "cut and paste".

I have two diferent exceptions comming from TreeServices.asmx

One when i try to move a file and other when i try to move a folder.

When i move a folder it pases throw the Update method in the provider, the update in Database is OK but then in treeServices when the SubmitChanges is made i get an exception:

Sorry, i didn't change the namespaces yet

Then when moving a file, it doesn't goes throw the Update method, but the TreeServices in the drag and drop throws an exception of invalid cast (it is trying to cast from my class Composite.Plugins.Data.DataProviders.DBMediaFileProvider.DBMediaFile: IFile to the Composite.Media.DBMediaFile type that is mapped to the database table):
