This question is regarding to BGL, I should have included it on the title.

First, Thank Doug for answering my previous question on parallel edges. Now, my question is:How to access bundled property individually?  
I defined my graph like this:

struct Node{  int label;  int mode[3];  //...;};struct Edge{  double nCommBord;}; typedef boost::adjacency_list<    boost::setS, boost::vecS, boost::undirectedS,    Node, Edge> Graph;but when I want to access property nCommBord of Edge, there seems to be wrong with my property_map type definition. Anyone can point out for me, what is the right version(I cannot seem to find any comment on this kind of usage)?  //get edgeWeight propertyproperty_map<Graph, &Edge::nCommBord>::type p_e = get(&Edge::nCommBord, *rowGraph); The error:c:\...\VCProjects\...xxx.cpp(55) : error C2974: 'boost::property_map' : invalid template argument for 'Property', type expected        c:\Boost\include\boost-1_33_1\boost\graph\properties.hpp(205) : see declaration of 'boost::property_map'Thanks, Shufei
