[2005] Streams question

Hi everyone

What kind of streams do I need to use to copy large files into a memory stream, process the data and copy it to a new file?

well i am not sure, but i will say use System.IO.BufferedStream . Because it works most like MemoryStream and it is constructed or initialised to some other existing Stream, in your case it could be a Text file, so you wont require external writing to a file using FileStream.

just my 2 cents.

How would I write into the buffer synchronously if the BufferedStream doesn't support seeking

FR is a FileStream (reader)
ES is a stream
FW is a FileStream (writer)

VB Code:

Dim BR As New System.IO.BufferedStream(Es)
            Dim buffer(1024) As Byte
            While FR.Position < FR.Length
                FR.Read(buffer, 0, 1024)
                BR.Write(buffer, 0, buffer.Length)
            End While
            Es.Close()
            FR.Close()
            While BR.Position < BR.Length
                Dim X As Integer = BR.ReadByte()
                If X <> -1 Then
                    FW.WriteByte(CByte(X))
                End If
            End While

in case the code helps you, the problem is the BufferedStream doesn't support seeking and I don't know what kind of stream to use

EDIT: I decided not use the MemoryStream
