hi all,
I have a code snippet that I don't know how to handle, and am looking for direction, examples, etc....

I have some code that could hang indefinitely, and what I need to do is stop the code from executing if it doesn't execute within n milliseconds.

here is an example.

//build and construct a socket...
// socket code here....
// everything works great..
// but if the socket doesn't get a response back, everything hangs....

socket.ReceiveFrom( UdpPacket, 0, 1024, SocketFlags.None, ref tempRemoteEP );

the socket.ReceiveFrom() method may never actually execute, because it is waiting for a packet back from the UDP (DHCP server) server. What I would like to do is wait for n milliseconds, and if the code doesn't execute, then continue with the execution of the program and handle not getting a response back.

What do I need to do, to achieve this?

Thanks,
dave
