使用这段代码，将出错代码转换成语言描述
LPVOID lpMsgBuf;
FormatMessage(

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.
AfxMessageBox((LPCTSTR)lpMsgBuf);
// Free the buffer.
LocalFree( lpMsgBuf );
