    <p>Let me start by saying I've extensively searched for answers on google and more specifically here.</p> <p>The thing is I actually (at least I think I did) found people with similar problems, though the answer given to them gave me another problem.</p> <p>I'm using Visual Studio 2010 Express and working with SFML libary (though i do not think this last part is relevant)</p> <p>So here it goes:</p> <p>I have a source file called player.cpp which holds class Player and I have a header file (included in all source files) called cc.h(command and control) that holds all the necessary includes and external variables/functions. The essential code can be summed up in the following:</p> <p>Player.cpp:</p> <pre><code>#include "cc.h" class Player { private: //some variables here public: //more variables and some functions }john;//example instance </code></pre> <p>cc.h:</p> <pre><code>#pragma once //some #includes //some externs extern Player john; </code></pre> <p>Now in cc.h the word Player is underlined as a mistake saying it is an <em>undefined identifier</em> , but only sometimes, other times visual studio doesn't mark it as a mistake, instead it recognizes it as a class but doesn't recognize john as an object/instance (i hope it's called this way) of that same class. Furthermore, at compiling the first error it shows is "<code>error C2146: syntax error : missing ';' before identifier 'john'</code>" at the line of the extern declaration of john, in cc.h, which apparently (to me) does not make any sense.</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.
