Body
In a couple of classes (in vlr namespace) in header files I have a public member of this form: <pre><code>std::multiset<classA,classB::ClassC> data_; </code></pre> in my program it is emptied somewhere and so I want to create a buffer to store its content before it is lost. so under every line of declaration the old member in classes in headers I add such a line: <pre><code>std::multiset<classA,classB::ClassC> data_buff_; </code></pre> and then for buffering I write in some .cpp file: <pre><code>data_buff_.insert(data_); </code></pre> and obtain here errorC4430: missing type specifier, int assumed. Can you help me, how should I properly buffer this data, because I was trying with giving namespace in the line I get error, and nothing helped. Many thanks! - - - - - - - - - update - - - - - - - - ClassA.h: <pre><code>namespace vlr { class A{ // some unimportant things } } </code></pre> ClassB.h: <pre><code>namespace vlr { class B{ // some unimportant things public: class C{ // some unimportant things } } } </code></pre> ClassD.h: <pre><code>#include <set> #include "ClassA.h" #include "ClassB.h" namespace vlr { class D { public: std::multiset<classA,classB::ClassC> data_; std::multiset<classA,classB::ClassC> data_buff_; // some other methods and members } } </code></pre> ClassE.h: <pre><code>#include <set> #include "ClassA.h" #include "ClassB.h" namespace vlr { class E { public: std::multiset<classA,classB::ClassC> data_; std::multiset<classA,classB::ClassC> data_buff_; // some other methods and members } } </code></pre> final.cpp: <pre><code>#include <set> #include "ClassA.h" #include "ClassB.h" #include "ClassD.h" #include "ClassE.h" namespace vlr{ // something data_buff_.insert(data_); data_.clear(); } </code></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.
