Hi, Trying someting like this typedef NodePtrSet::index<hndl>::type index_hndl_type; //complier complains two few arguments Note: hndl is a tag name //// so I defined the following: typedef nth_index<NodePtrSet,0>::type hndl_index_type; typedef nth_index<NodePtrSet,1>::type group_index_type; ... When I try to write group_index_type& g_type = get<group>(ns); // tag<group> complier tells me the I have to increase /Zm which i did.(to /Zm1024) but still I receive this annoying message. z:\boost\mpl\aux_\preprocessed\msvc60\iter_fold_if_impl.hpp(65) : fatal error C1076: compiler limit : internal heap limit reached; use /Zm to specify a higher limit If I apply this line instead hndl_index_type & h_type = get<hndl>(ns); I get the following errors: //error C2667: 'get' : none of 2 overload have a best conversion //error C2668: 'get' : ambiguous call to overloaded function What I care is to get access using my keys and I don't know how to do it I am able to run on the first one with no problem e.g doing the following NodePtrSet::iterator it = ns.find(theHandle); //works 1. How to i rewrite the latter line to explictly tell it to find theHandle? 2. How to I get access to the non_unique_index This is too good to give up on Can someone help me?

Hello,
I having difficulties getting multi_index working with shared_ptr
Example code:
typedef multi_index_container<
NodePtr,
indexed_by<
ordered_unique<
BOOST_MULTI_INDEX_CONST_MEM_FUN(NodePtr, handle, getHandle)
>
>
> node_set;
NodePtr is a typedef to boost::shared_ptr<NodeBase>
NodeBase is an interface for other NodeTypes objects the use it.
NodeBase ::getHandle() : handle (handle==size_t)
Using MSVC++ 6.0 compilers complains that getHandle is not a member of NodePtr
If I replace NodePtr with NodeBase class it compiles, with a price of giving away shared_ptr abilty.
Does anyone have any idea how to get both libs work?
OK. You should define your NodePtr_set as follows
typedef multi_index_container< NodePtr, indexed_by< ordered_unique< BOOST_MULTI_INDEX_CONST_MEM_FUN(NodeBase,handle,getHandle) > >
NodePtr_set;
Note that elements are NodePtrs, but the index is based on NodeBase.
This is explained at
http://boost.org/libs/multi_index/doc/advanced_topics.html#advanced_key_extr...
It is possible that you missed that part.
