[CONNECT C++] ViewGroups and ViewInfo

When we do something like this (taken from SDK ..\Visualization\DisplayStyleExample)...

    ViewGroupCollectionCR viewGroups = dgnFile->GetViewGroups();
    ViewGroupPtr viewGroup = viewGroups.GetActiveP();
    if (!viewGroup.IsValid())
        return;
    int viewIndex = 0;
    ViewInfoR viewInfo = viewGroup->GetViewInfoR (viewIndex);

• Is the active ViewGroup always available when MicroStation has a DGN file open?
• Do all eight ViewInfo instances exist even when some views are closed?
