CAsyncSocket close problem

[bkelly]

Environment: windows XP and Win 7, Visual Studio 2008, MFC, C++, CAsyncSocket

Setup: I wrote a test program that drives the server side and the client side of a TCP/IP connection using CAsyncSocket. It uses a C_Server class to listen for the client and accept the connection. That class creates an instance of the C_Server_Send object to send data to the client. It is working but is missing the proper closing function. I am working on fixing that. Now when the client closes the socket the C_Server_Send OnClose() is called. But I don’t know what to do here. The CAsyncSocket::Close does not appear to cause the object to delete itself. C_Server does not know that OnClose() has been called so the object that created this cannot delete it.

Question:
When the client closes the connection, what is the proper method to delete object CAsyncSocket?

Question:
In all the On*() overridden methods, should I load them up with error checking such as WSAGetLastError()?

Note: If interested, I wrote up an article on this and posted it on codeproject.com here:

I have since realized that while it ends with error code zero, it still does not have proper closing code. That work is in progress. I discovered this as I started implementing my code in a real world application.
