I am using the atom format you have send and I still get the same error. Please find attached the code to generate the Portfolio.

When trying to get webrequest.GetRequestStream() the following stack is shown:

- stOut {System.Net.ConnectStream} System.IO.Stream {System.Net.ConnectStream} + [System.Net.ConnectStream] {System.Net.ConnectStream} System.Net.ConnectStream + base {System.Net.ConnectStream} System.MarshalByRefObject {System.Net.ConnectStream} CanRead false bool CanSeek false bool CanTimeout true bool CanWrite true bool - Length 'stOut.Length' threw an exception of type 'System.NotSupportedException' long {System.NotSupportedException} + base {"This stream does not support seek operations."} System.SystemException {System.NotSupportedException} - Position 'stOut.Position' threw an exception of type 'System.NotSupportedException' long {System.NotSupportedException} + base {"This stream does not support seek operations."} System.SystemException {System.NotSupportedException} ReadTimeout 300000 int WriteTimeout 300000 int + Static members + Non-Public members

Please guide.

Thanks,

SB
