Call this function to check if the bitmap list is locked. If this class object was created using the LBitmapList::GetItem, LBitmapList::GetFirstItem, LBitmapList::GetLastItem, LBitmapList::GetPreviousItem, or LBitmapList::GetNextItem functions, then the bitmap list will be locked until you restore the bitmap to the list using the LBitmapList::SetItem function.
