I'm not sure if I'm getting what is what you want to get, but if you want to save each element of type <code>Node</code> with a different identifier you may try the next: <pre><code>pair<char, Node> node_with_name; </code></pre> And then you can assign the name to the first element doing <code>build >> node_with_name.first;</code> , then put the rest of the elements in the node and assign it in the same way to the second position of the <code>pair</code>. And the vector should also be changed in order to use this solution: <pre><code>std::vector<pair<char, Node> > nodes; </code></pre> And finally you would do: <pre><code>nodes.push_back(node_with_name); </code></pre> in every iteration of the loop. <hr> Edit: I think that a <code>map</code> would possibly fit better to your needs. I will show you an example: <pre><code>std::map<char,Node> mymap; do { char name; // to store temporarily each node's name build >> name; build >> mymap[name].north; // we start getting the data for the node with this name build >> mymap[name].east; build >> mymap[name].south; build >> mymap[name].west; }while(! build.eof()); </code></pre> And then you can output each node's data with: <pre><code>std::cout << "mymap['A'].north is " << mymap['A'].north << '\n'; </code></pre> Map reference: <a href="http://www.cplusplus.com/reference/map/map/operator%5B%5D/" rel="nofollow">http://www.cplusplus.com/reference/map/map/operator%5B%5D/</a> Pair Reference: <a href="http://www.cplusplus.com/reference/utility/pair/" rel="nofollow">http://www.cplusplus.com/reference/utility/pair/</a>

1. COI think this is close. However, I still am unsure of what exactly is going on. I got the program to compile with the snippets of code you showed me, but what is node_with_name ? When I try to cout A.name, or A.east, the compiler is telling me that no declaration was made. What am I missing here? <pre> pair<char, Node> node_with_name; do { build >> node_with_name.first; build >> node.name >> node.north >> node.east >> node.south >> node.west; nodes.push_back(node_with_name); } while(! build.eof()); </pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
