    <p>I have a native app written in c++ and a chrome-extension.</p> <p>I am communicating between them using 'chrome native messaging'.</p> <p>Native-App code:</p> <pre><code>int main(int argc, char* argv[]) { unsigned int a, c, i, t=0; std::string inp; do { inp=""; t=0; // Sum the first 4 chars from stdin (the length of the message passed). for (i = 0; i &lt;= 3; i++) { t += getchar(); } // Loop getchar to pull in the message until we reach the total // length provided. for (i=0; i &lt; t; i++) { c = getchar(); inp += c; } // Collect the length of the message unsigned int len = inp.length(); //// We need to send the 4 btyes of length information std::cout &lt;&lt; char(((len&gt;&gt;0) &amp; 0xFF)) &lt;&lt; char(((len&gt;&gt;8) &amp; 0xFF)) &lt;&lt; char(((len&gt;&gt;16) &amp; 0xFF)) &lt;&lt; char(((len&gt;&gt;24) &amp; 0xFF)); //// Now we can output our message std::cout &lt;&lt; inp &lt;&lt;std::endl; flushall(); }while(cnt &lt; 2 ); return 0; } </code></pre> <p>Here I'm reading message sent by chrome-extension on stdin. and sending the same message back by writing it on stdout.</p> <p>Extension is using PostMessage()</p> <p>This is working... BUT ..</p> <p>When I put my program under continuous while loop, the flow executes only once!</p> <p>i.e port.postMessage({'text':'hello_1'}) gets echoed back as expected but if I do</p> <p>port.postMessage({'text':'hello_2'}) it doesn't get echoed back.</p> <p>I'm unable to understand what the problem is. Does it require threading?</p> <p>Please help!</p> <p>Thanks!</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.
