    <p>That is part of the DFM file, which you don't edit directly. I just placed a TIdTCPServer on a form and the DFM shows:</p> <pre><code>object IdTCPServer1: TIdTCPServer Bindings = &lt;&gt; DefaultPort = 0 Left = 80 Top = 112 end </code></pre> <p>You can see this for yourself if you right click on your form and choose 'View as Text' (or if you inspect the .DFM files in an editor <strong>if</strong> you have your configuration set to save them as text.</p> <p>When you start filling in more (non-default) properties of the TIdTCPServer, Delphi will store these in the DFM as well. I don't see a CommandHandlers property in my Delphi version (XE2, Indy 10.5.8.0), but yours has one (in the example).</p> <p>[Edited to add] I see from your comment on another answer that you do not have a CommandHandlers property for TIdTCPServer either, this may indicate that the book author used a different Indy version than you do. You can see your version by right-clicking on any Indy component on the form.</p> <p>CommandHandlers are indeed old. <a href="https://www.google.com/search?q=tidtcpserver+commandhandlers" rel="nofollow">Googling "tidtcpserver commandhandlers"</a> leads to e.g. <a href="http://forums2.atozed.com/viewtopic.php?f=7&amp;t=105" rel="nofollow">"The CommandHandlers collection was moved to a new TIdCmdTCPServer component in Indy 10."</a> That makes me suspect you have Indy 10 and the book references 9. You'll have to find Indy 10 examples for what you want to do. <a href="https://www.google.com/search?q=tidtcpserver+tidcmdtcpserver" rel="nofollow">That should not be too difficult</a>.</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.
