    <p>I have a point3 struct with 3 floats x y z (coordinates in 3-D space). </p> <p>I create a few instances of point3, and then create a list and push those instances onto the list. Then I apply a translation function to the entire list.</p> <p><strong>Question:</strong> After applying the translation, how can I print out the X coordinate of one of the points in the list to check if my translation function does what I want it to?</p> <p>Here is my code:</p> <pre><code>int main() { point3 p1 = point3(0.0f, 0.0f, 0.0f); point3 p2 = point3(1.0f, 1.0f, 1.0f); point3 p3 = point3(2.0f, 2.0f, 2.0f); list&lt;point3&gt; myList; myList.push_front(p1); myList.push_front(p2); myList.push_front(p3); list&lt;point3&gt; myList2 = translateFact(myList, 1, 1, 1); std::cout &lt;&lt; myList2.front.x; //&lt;--- This is the line I'm having trouble with } //Translates the face by dx, dy, dz coordinates list&lt;point3&gt; translateFact(list&lt;point3&gt; lop, float dx, float dy, float dz) { list&lt;point3&gt;::iterator iter; for (iter = lop.begin() ; iter != lop.end(); iter++){ point3 p = *iter; iter-&gt;x - dx; iter-&gt;y - dy; iter-&gt;z - dz; } return lop; } </code></pre> <p>The error I receive when trying to print myList2.front.x is</p> <pre><code>IntelliSense: a pointer to a bound function may only be used to call the function </code></pre> <p>so I think my issue is related to pointers, but I am unsure how. I just picked up C++ recently so I don't know enough about pointers to diagnose/fix the error.</p>

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.
