SetSocketOption fails for SocketOptionName ReceiveTimeout

[Nathan Kerr]

I have been working with KB Article 812404 "HOW TO: Write
Pluggable Protocol to Supprot FTP in Managed Classes by
Using Visual Bassic.NET".

I have modified the code to run on a Pocket PC. In the
OpenControlConn ection routine the following lines are
being executed:

m_DataSocket.Se tSocketOption
(SocketOptionLe vel.Socket, SocketOptionNam e.SendTimeout,
m_ConnectTimeou t)
m_DataSocket.Se tSocketOption
(SocketOptionLe vel.Socket,
SocketOptionNam e.ReceiveTimeou t, m_DataReceiveTi meout)

The SendTimeout one works. The ReceiveTimeout fails with:
---------------------------------------------------------
An unhandled exception of
type 'System.Net.Soc kets.SocketExce ption' occurred in
System.dll

Additional information: An unknown, invalid, or
unsupported option or level was specified in a getsockopt
or setsockopt call
----------------------------------------------------------

I assume this works with regular projects. The
documentation says that ReceiveTimeout is supported by the
compact framework.

Am I running into a bug in the compact framework?
