Hello john,
You really dont have to play around with bits and bytes. Every Soap based
Object has a LoadXml and GetXml that you can use in conjunction with a XmlTextReader/Writer.
So all you need to do is write to the chained stream using an xml writer.
But u do have to chain the stream to be able to alter the stream
HTH
