actionscript 3 - OOP: trouble notifying other objects in hierarchy -

-

I consider the hierarchy of objects I always struggle quiz with sending messages between objects:

< ul>
  • Quiz
    • Prsnsuchi
      • question
        • North list
          • Answer

    • it:
    a quiz question list - multiple questions in a question list - no question a Answer list is there
    There are many answers in a reply list

    When someone Answer is clicked (We are talking Flash AS3 here):
    Answer indicates the answer.
    Answers the question answers. The question indicates question listing. The quiz indicates the quiz.

    In other words, the message bubbles up. This is possible because I pass each 'parent' object through the creator of its 'collector' but I think I read somewhere that the objects should not be aware of their parents.

    Thank you

    Yes, you do not want children to their parents Let object link I think you have to expand the position, he has a performance hierarchy that case, you can do it better by using the event system. You can create custom events that are sent when things happen and parents will add events to the care of them to take care of them.

    A possible event scenario for your structure would be the following example:

    • The answer (a button) is clicked, and the hearing list answers the notice.
    • A "answered" event is posted in the answer list, which is received by the question.
    • "Answered" event has been sent to inform the question list for marking this question as answer to the question
    • When the question list answers all the questions If the given events have been received, it tells an "end" event it is complete that the quiz

    c# - How to capture HTTP packet with SharpPcap -

    -
    I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
