I have an application that uses DIME to send and receive attachments. Now I
want to migrate to WSE 3.0 and as I understand it DIME is not supported. I
got lost with the web pages on how to send/receive large amounts of data.
Maybe someone can help me translate WSE 2.0 code to WSE compatible code or
explain the differences and what needs to be done. Currently I have overrides
like:

Public Class SoapEnvelopeWithAttachment
Inherits SoapEnvelope
.. . .
Public Overrides Sub WriteToStream(ByVal StreamToWriteTo As
System.IO.Stream, ByVal closeStream As Boolean)

.. . .
Public Shared Function ReadFromStream(ByVal InStream As
System.IO.Stream) As SoapEnvelopeWithAttachment

These functions are called like:


If RequestType = MessageFormat.Application_Dime Then
DirectCast(se,
SoapEnvelopeWithAttachment).WriteToStream(objRequest.GetRequestStream(), True)
Else
se.WriteToStream(objRequest.GetRequestStream(), True)
End If


and

If ResponseType = MessageFormat.Text_Xml Then
. . .
Return seResponse
Else
If objResponse.ContentType.IndexOf("application/dime") = -1
Then
Throw New Exception("Expected response of contenttype
'application/dime'")
End If
seResponseWA =
SoapEnvelopeWithAttachment.ReadFromStream(objResponse.GetResponseStream)
objResponse.Close()
Return seResponseWA
End If

What needs to happen to convert this application to use MTOM (or Mime)? I am
not sure what the reason to move away from Dime or what the advantages of
MTOM are.

Thank you for your patience.

Do you have the full article that you could forward to me? It seems to reject
