You are great!Thank you!

Now I have corrected it by override OnConnect(...),
during OnConnect(...),nErrorCode==0,it shows that there is no error,
and after Connect(...) I called GetLastError(...) it showed
WSAEWOULDBLOCK error, which is no problem.


to the first point you said,I have a word to say:
the GetLastError(...) I called is the member function of
class CAsyncSocket,will it return the result of AfxMessageBox(..)?

I am a newer,Thank you for your help!
