Hi,

here is the code for uploading a file to a database.please check this code
Dim fLen As Integer, btData() As Byte
Dim objStream As System.IO.Stream
Dim insSql As String
insSql = "Insert Into SP_File(File_Name,File_Length,File_Data)
Values(@fName,@fLen,@fData)"
Dim Insertcmd As SqlCommand = New SqlCommand(insSql, cn)

Try
fLen = Me.tFile.PostedFile.ContentLength
ReDim btData(fLen)
objStream = Me.tFile.PostedFile.InputStream
objStream.Read(btData, 0, fLen)
Insertcmd.Parameters.Add(New SqlParameter("@fName",
SqlDbType.NVarChar, 50)).Value = Me.tFile.PostedFile.FileName
Insertcmd.Parameters.Add(New SqlParameter("@fLen",
SqlDbType.BigInt, 8)).Value = fLen
Insertcmd.Parameters.Add(New SqlParameter("@fData",
SqlDbType.Image, 16)).Value = btData

Insertcmd.Connection.Open()
Insertcmd.ExecuteNonQuery()
Insertcmd.Connection.Close()
Catch ex As Exception
Me.lblError.Text = ex.Message
End Try
