ASP.NET

Wrox:

In C# and ASP.NET:
I'm looking for a way to upload a binary file (Word Document, JPEG, etc) and store it to a Database (Access or SQL).
Then able to view the file in the clients browser or download it to the client machine.

I hope someone can point me to a book which explains this or can write a tutorial.

Thank you !!

So where should I copy-paste this code and how do I use it?
