UpNP and NETLINX

Hi,

I was wondering if anyone could shed some light on how to send UPnP commands from Netlinx or a Netlinx Module. It would be greatly appreciated if anyone could post an example.

define_function addURIToQueue(long lInstanceID, char sID[], 	 char sParentID[],  char sRestricted[],  char  sTitle[],  char sClass[], integer bPlayNow, integer bPlayNext)
{
	stack_var volatile char sCmd[2048]
	stack_var volatile integer length


	sCmd = "stEnvelope.sOpenTag,
		'<s:Body>',
		'<u:AddURIToQueue xmlns:u="urn:schemas-pnp-org:service:AVTransport:1">',
		'<InstanceID>',itoa(lInstanceID),'</InstanceID>',
		'<EnqueuedURI>',sID,'</EnqueuedURI>',
		'<EnqueuedURIMetaData>',
		'&lt;DIDL-Lite ',
		'xmlns:dc=&quot;http://purl.org/dc/elements/1.1/&quot; ',
		'xmlns:upnp=&quot;urn:schemas-upnp-org:metadata-1-0/upnp/&quot; ',
		'xmlns:r=&quot;urn:schemas-rinconnetworks-com:metadata-1-0/&quot; ',
		'xmlns=&quot;urn:schemas-upnp-org:metadata-1-0',
		'/DIDL-Lite/&quot;&gt;',
		'&lt;item id=&quot;',sID,'&quot; ',
		'parentID=&quot;',sParentID,'&quot; ',
		'restricted=&quot;',sRestricted,'&quot;&gt;',
		'&lt;dc:title&gt;',urlEncode(sTitle),'&lt;/dc:title&gt;',
		'&lt;upnp:class&gt;',sClass,'&lt;/upnp:class&gt;',
		'&lt;desc id=&quot;cdudn&quot; nameSpace=&quot;urn:schemas-rinconnetworks-com:metadata-1-0/&quot;&gt;',
		'RINCON_AssociatedZPUDN&lt;/desc&gt;',
		'&lt;/item&gt;',
		'&lt;/DIDL-Lite&gt;',
		'</EnqueuedURIMetaData>',
		'<DesiredFirstTrackNumberEnqueued>',itoa(bPlayNext),'</DesiredFirstTrackNumberEnqueued>',
		'<EnqueueAsNext>',itoa(bPlayNow),'</EnqueueAsNext>',
		'</u:AddURIToQueue>',
		'</s:Body>',
		stEnvelope.sCloseTag"

	length = length_string(sCmd)
	
	sendToControlPort( "stHeader.sPOST[cnServiceAVTransport],cnNL,
					stHeader.sConnection[cnConnectionClose],cnNL,
				       stHeader.sAcceptEncoding[cnEncodingZip],cnNL,
					stHeader.sHost,cnNL,
					stHeader.sUserAgent[cnUserAgentSonos],cnNL,
					stHeader.sContentLength,itoa(length),cnNL,
					stHeader.sContentType[cnContentTypeTextXML],cnNL,
					stHeader.sSoapAction[cnSoapAddURIToQueue],cnNLNL,
					sCmd")
}

Theres also some good books around, there's an Intel one that I used to get background info when I was developing a Module for a mediastreamer. Its partly about UPNP design but it gives you all the basic - think its called UPNP design by example - I found it quite useful. Also there is quite a bit on the web, some of it crap, some good.

As others have said, it depends what you are looking for....
