Have you tried looking in the Database Connectivity Toolkit documentation yet? I've implemented sending all kinds of data to a SQL database with its help. You can find it at:

http://digital.ni.com/manuals.nsf/websearch/F0E03761C7F4ACB486256A3E00509BA9?OpenDocument

I'm not aware of how to use the Appendchunk function in LabVIEW. I'm not sure what will be the best way to store your data. You send/receive data with this toolkit using variants, but you might have to tell the database you are sending up a string. So unless you can send up the file, you'll need to open up the file and send its contens up as a string. If I'm wrong about that is there someone that knows how to send up a file to a DB with this toolkit?

Hope that helps!

Correct me if I am wrong

Appendchuck belongs to ADO, which is a microsoft is a set of Component Object Model, so I think it could be implemented using ActiveX method.
