//
// Description:
//      This file implements ResetAnswersToDefaults().  It is called by
//      load.c every time the user hits NEXT on the NewOrEditPage.
//
//      You MUST reset your global data to true defaults and you MUST
//      free any memory you allocated to hold setting info.

//----------------------------------------------------------------------------
//
//  Function: ResetAnswersToDefaults
//
//  Purpose: This function is called before we (possibly) load settings
//           from elsewhere.  This is time to zero stuff out and free
//           relevant stuff.
//
//           In case you need to do something different based on the reason
//           we're resetting, iOrigin is passed in.  But note, in case of
//           LOAD_NEWSCRIPT_DEFAULTS, and LOAD_TRUE_DEFAULTS all work should
//           be finished when this routine finishes.
//
//  Arguments:
//      HWND hwnd    - current window
//      int  iOrigin - how will we be setting the default answers?
//
//  Returns: VOID
//
//----------------------------------------------------------------------------

    //
    // This is done by first zeroing out GenSettings & WizGlobals and then
    // assigning specific fields where 0 isn't the good default.
    //
    // Note that FixedGlobals does not get reset by design.  You can declare
    // staticly initialized lists and such in there.  For example, the timezone
    // page has a fixed list of valid timezones built at wizard init time.
    // But the current user selection is in GenSettings.  The user selection
    // gets reset as it should and the list of valid timezones never gets
    // reset, as it should be.
