Why can't I create CSocket derived socket?

[yysheep]

m_pSocket = new CListeningSocket(this);
if( m_pSocket->Create(SOCKET_PORT) )
...
an error "10093" is got. Can anybody tell me what does that mean? thx

I did a lookup and found that the code error means "Either the application has not called WSAStartup, or WSAStartup failed. "

If you are using MFC, it is very likely that you didn't call AfxOleInit() in CWinApp::InitInstance().

Hope that helps.

I don't know if AfxOleInit includes WSAStartup. WSAStartup(...) is a routine that loads the WinSock dll, and must be called before you do anything else in WinSock.

Oh no, I am very sorry. I had made an mistake and function I meant should be AfxSocketInit(). This function will call WSAStartup() and ensure that WSACleanup() is called before the program terminates.

Should be more carefull next time.

Exactlt where in the application do you put that code - AfxSocketInit()?

[yysheep]

InitInstance()
