Re: The reason: It's so small that I honestly have great difficulty connecting alligator clips to the various pins. Forget the alligator clips. Get a crimper and some socket and pin ends that match the connector or pins available. Crimp the pin/socket on the end of your wire and put anything you want on the other end. Use various colors of wire to make it easy. To the OP, do some googling on demo and prototype boards. If you are really serious, for less than $100 you can get a demo/prototype board for just about any type of processor. Usually way less. Edit: Get some heat shrink tubing to insulate the crimped end.

Windows 7, Visual Studio 2012, winsock Edit: Oops, posted in ATL rather than C++. If you are an admin type, please move it. How is an event associated with a socket operation? For example: [code]

// start listening for new clients attempting to connect
iResult = listen(ListenSocket, 1);

[/code] The socket is non-blocking and the code continues while waiting for the listen operation to complete. I want event: CLIENT_DETECTED (arbitrary name, I know how to create the event.) to be triggered when a client solicits a connection. Yes, I understand a bunch of code is needed to capture that event and do something. Thank you for your time.
