Uploading A File To A SQL Database Via A Typed Dataset And Using The FileUpload Control.

I am trying to upload a file in ASP.net 2.0 to a SQL database using the FileUpload control. I am doing this by way of a typed dataset.
Here is my code.
Dim rta As New ResponseTableAdapter
Dim rdt As ResponseDataTable = rta.GetResponseByID(1)
Dim rr As ResponseRow = rdt(0)
Dim fs As New FileStream(fu.PostedFile.FileName, FileMode.Open, FileAccess.Read)
Dim br As New BinaryReader(fs)
Dim image() As Byte = br.ReadBytes(fs.Length)
br.Close()
fs.Close()
rr.UploadFile = image
rr.NameFile = fs.Name
rta.Update(rdt)
The code runs without an error but afterwards I find that nothing has been stored in the UploadFile cell in the database but the file name has been stored in the NameFile cell in the database. Any ideas?
Your help is much appreciated.
