    <p>I called <code>dgram.setBroadcast(flag)</code> and it returned a <em>not yet implemented</em> error on Node.js version v0.6.3.</p> <p>Does Node.js still support UDP broadcasting? </p> <p><em>Edit: I found <a href="http://groups.google.com/group/nodejs/browse_thread/thread/c294ead91fde78e2?pli=1" rel="nofollow">some discussions</a> said that broadcast was removed in 0.5.x and probably be back in the future.</em></p> <p>still <strong>not</strong> yet implemented in <strong>v0.6.6</strong></p> <p>I tried 0.6.10 in windows 7 x64, the multicast did not work yet.</p> <pre><code>var dgram = require('dgram'); var PACKET_LEN = 64; var message = new Buffer(PACKET_LEN); var client = dgram.createSocket("udp4"); client.setMulticastTTL(128); //dgram.addMembership(multicastAddress, [multicastInterface]) client.addMembership('234.18.128.10', "172.18.128.64") ; // dgram.send(buf, offset, length, port, address, [callback]) client.send(message, 0, PACKET_LEN, 7000, "234.18.128.10"); client.close(); I got an "Error: addMembership EADDRNOTAVAIL". </code></pre> <p>after ref here: <strong>https://github.com/joyent/node/blob/master/test/simple/test-dgram-multicast-multi-process.js</strong> , I finally make multicast work on my windows pc. <br /> node ver=0.6.19</p> <pre><code>var dgram = require('dgram'); var message = new Buffer('this is my message'); var client = dgram.createSocket("udp4"); client.bind(); client.setBroadcast(true) client.setMulticastTTL(128); client.send(message, 0, message.length, 5007, "224.1.1.1"); client.close(); </code></pre>

    1. COWell in the discussion says that it will be back in v0.6.4 or v0.6.5. Version 0.6.4 is due to 3 days, and probably one more week for 0.6.5.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
