Body
<pre><code>#include <iostream> using namespace std; class Object{}; class Connection { public: Connection(Object * _obj); Object * obj; void status(); }; Connection::Connection(Object * _obj) { obj = _obj; } void Connection::status() { cout << obj << endl; } int main() { Object * myObj = new Object(); Connection * myConn = new Connection(myObj); delete myObj; myObj = NULL; cout << myObj << endl; myConn->status(); /* Output is: 0 0x25ec010 but should be: 0 0 */ } </code></pre> <p>I thought I am only working with pointers in this example. So I don't understand why the pointer in "myConn" is not set to NULL too, because there are two pointers which point to the same address.</p>

Guidance

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.
