    <p>In MSVC++ #include files are searched for differently depending on whether the file is enclosed in "" or &lt;>. The quoted form searches first in the local folder, then in /I specified locations, The angle bracket form avoids the local folder.</p> <p>This means, in MSVC++, its possible to have header files with the same name as runtime and SDK headers.</p> <p>So, for example, I need to wrap up the windows sdk windows.h file to undefine some macro's that cause trouble. With MSVS I can just add a (optional) windows.h file to my project as long as I include it using the quoted form :-</p> <pre><code>// some .cpp file #include "windows.h" // will include my local windows.h file </code></pre> <p>And in my windows.h, I can pull in the real one using the angle bracket form:</p> <pre><code>// my windows.h #include &lt;windows.h&gt; // will load the real one #undef ConflictingSymbol </code></pre> <p>Trying this trick with GCC in XCode didn't work. angle bracket #includes in system header files in fact are finding my header files with similar names in my local folder structure. The MSVC system means its quite safe to have a "String.h" header file in my own folder structre. On XCode this seems to be a major no no.</p> <p>Is there some way to control this search path behaviour in XCode to be more like MSVC's? Or do I just have to avoid naming any of my headers anything that might possibly conflict with a system header. Writing cross platform code and using lots of frameworks means the possibility of incidental conflicts seems large.</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.
