* SnapinVirtualItem.hxx * * * Copyright (c) 1998 Microsoft Corporation * * PURPOSE: Defines the CVirtualSnapinItemImpl class. * This class is used in the same way as the * CBaseSnapinItem class. Except the virtual snapin * class is only supposed to be used in a virtual results pane. * These snapin items are created as needed and go away when * not in use anymore. This is because they are in a virtual * list and so we just do not have memory to support all the * list elements at one time. * * This class puts asserts around all functions that should * NOT be called. Since we are virtual we should never be * a scope item and these asserts protect against this from * happening. * * OWNER: mcoburn */
