I would like to know if it is possible to use the CAsyncSocket class
within a console application (Visual Studio 2005). The item I am
having problems with is that it seems the CAsyncSocket wants a
CDialog* to be sending messages to (OnAccept, OnReceive, etc.). If it
is not possible to use CAsyncSocket what other alternatives would you
suggest for doing socket communications.

Thank you,


CAsyncSocket relies on windows messages coming in to an invisible window
that it creates. This means that it can only work in an MFC-created thread
that pumps messages. The main thread of a console application does not do
this, but you could create an MFC UI thread and do all the socket work in
that thread.

If you don't want to have to use multithreading then you can directly use
the winsock APIs. In particular, WSAEventSelect will let you use
nonblocking sockets within a single-threaded console app.
