I can create a simple program that works, but the wizard is setting
everything up for me. Inside of my larger app I can use the wizard to
create an entire new application using windows sockets. it's my
understanding that once the socket's buffer is filled with data that
the framework automatically calls the OnReceive function. In my
application this isnt happening. What are some of the reasons why the
framework wouldn't call the OnReceive function? Is there somewhere
that the function needs to be registered or something? I'm lost
because i can establish a connection and send data to the buffer but
my OnReceive method is never triggered. Any suggestions would be
greatly appreciated.

Did you derive a class from CAsyncSocket and override the OnReceive
function? You must do that.

Is your code sitting in a loop or Sleep waiting for the OnReceive? You
must not do that. OnReceive will only be called while your program is
processing windows messages, which is only done when you return to MFC.
