I need to create a socket class to be used for discovery broadcasts and acknowledgements (like DHCP). I've done this successfully in Windows XP( Win32/VC++ 6.0), but haven't had success in Windows CE 3.0 (Pocket PC 2002).

I tried to use the CAsyncSocket class, but haven't been able to get the OnReceive notification to work. Does anyone know if the CAsyncSocket class included with WinCe is capable of asynchronous OnReceive notifications, or if only the CCeSocket class has working notifications?

I know about the OnReceive bug for CCeSocket that required manually setting the m_bConnectCalled to TRUE, but don't see how this would work for a connection-less UDP socket.

Moreover, if CCeSocket is the only socket class that supports asynchronous notifications in WinCE, does anyone know if its possible to create UDP (SOCK_DGRAM) sockets instead of the default TCP (SOCK_STREAM) sockets? The CCeSocket::Create() doesn't allow specifying this, so I don't see how to create UDP socket class with notifications.

Any help or suggestion would be greatly appreciated. Examples of working UDP socket code for WinCE would be great.

Thanks,
Ishan
