  1. Reading UDP packets works but only works again after a timeout.

    I have a problem that is driving me demented.

    I have a PC running XP (or W7, makes no difference) that has a direct Ethernet connection to a DSP (no routers in the way).

    Super Jumbo Frames on Windows

    I have a PC connected directly to a DSP by Ethernet.

    Is it possible to get Windows (XP or 7) to send frames significantly larger than 9KB?
    If so, how?
  3. Re: SetTimer/OnTimer causes file menu to flicker.

    The thread you reference seems to be suggesting what I am already doing.

    Unless I've missed something, the handler is not only called when the user clicks a menu item; as discussed earlier it is...

    void MyDoc::OnUpdateFileApplication(CCmdUI *pCmdUI) {
    pCmdUI->Enable(Running==false);
    UINT Enable = (Running==false) ? MF_BYPOSITION | MF_ENABLED
    :...
  5. Re: SetTimer/OnTimer causes file menu to flicker.

    That's essentially what I have. Unfortunately the simple call to Enable resulted in the menu never being re-enabled,
    so the code grew other stuff and that is probably causing the problem. I can...
  6. Re: SetTimer/OnTimer causes file menu to flicker.

    The call to the base class was in the original code that was commented out. Putting it back in makes no difference.

    WM_INITMENUPOPUP messages are not mentioned in the code.

    OnUpdate is handled...

    I have traced...

    Re: Unable to read UDP broadcasts

    Thanks for that.

    I am reminded of the advice of a very wise teacher many years ago: the number one rule of programming is "never fiddle with a user's data".

    Life would be so much easier if...

    Re: Unable to read UDP broadcasts

    I do not see the relevance of this code which relates to multicast issues. My problem is clearly stated as being unable to receive broadcast packets.

    My problem has not been resolved.
