In my previous blog, I have described how to install and configure the RBS FILESTREAM Provider in a SharePoint 2010 system to store files from SharePoint in a disk file system. However, when a user uploads a file in SharePoint, the binary content of the file is written to the specified disk folder through the RBS FILESTREAM Provider. RBS can greatly improve the ability of SharePoint storage files and effect

This is just a bit of tweaking the code that uses WIN32 to manage FILESTREAM data, enabling access with progress, which is more useful for accessing larger files.

These two days in the study of how to write a RBS Provider, unfortunately the document is very scarce, basically in addition to a spec, only the SQL product group wrote a sample. Then if the research has results, then put it into the article, now let's talk about how to install and use the RBS FILESTREAM Provider directly.
If you use SharePoint 2007 as your document management platform, it's a big criticism that SharePoint 2007 stores the file itself
The main idea of using FileStream to realize multimedia file copying is to use two FileStream objects, one to read bytes and the other to write bytes. Knowledge points involved:1. The file class that we usually manipulate, filestream,streamwriter,streamreader, is under the System.IO namespace.the difference between the 2.File class and the
When restoring the adventureworks sample database, the filestream feature is disabled error message is displayed.
Filestream is a new feature added by SQL Server 2008. It is disabled by default. If this feature is enabled for the DB Backup file, enable this feature is also required for restoration on another server.

This topic explains how to create a database that supports FILESTREAM. Because FILESTREAM uses a special type of filegroup, the CONTAINS FILESTREAM clause must be specified for at least one filegroup when the database is created.
