MFC总是创建套接字失败

MFC总是创建套接字失败

把这句if (!m_pSocket->Create(70))
改成if (!m_pSocket->Create(0))
试试看，还报错吗

或者调用GetLastError看看问题出在哪里
追问：改为零也不行，GetLastError()我不会用啊，麻烦了啊
追答：LPVOID lpMsgBuf;
FormatMessage(
FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_FROM_SYSTEM |
FORMAT_MESSAGE_IGNORE_INSERTS,
NULL,
GetLastError(),
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
(LPTSTR) &lpMsgBuf,
0,
NULL
);

// Process any inserts in lpMsgBuf.
// ...

// Display the string.
MessageBox((LPCTSTR)lpMsgBuf, _T("Error"), MB_OK | MB_ICONINFORMATION );

// Free the buffer.
LocalFree( lpMsgBuf );
