如果您经常这样做，您可能需要考虑一个使其快速简便的功能。

int MsgBoxPrint(HWND hWnd, int Type, char *Caption, char *Format, ...)
{
    va_list ArgList;
    char Temp[4096];

    va_start(ArgList, Format);
    vsnprintf(Temp, 4096, Format, ArgList); 
    va_end(ArgList);

    return MessageBox(hWnd, Temp, Caption, Type);
}

然后你会这样称呼它：

MsgBoxPrint(hdlg, MB_OK | MB_ICONINFORMATION, "Logon Message", \
     "Your password will expire in %d days", pwdexpirydays);

您可以使用snprintf或 std::string 进行连接。
