I just tested this with Slim Connector v1.2.7.1 and it appears to work
correctly for me. Can you be more specific on the message you're
sending in case that's it (although as you say the display says
"playlist index ?" then that should be working fine.

I sent this message with Send:

xap-header
{
v=12
Hop=1
UID=FF123400
Class=xAP-Audio.Query
Source=KCSoft.Send.Anya
}
Playlist.Query
{
Query=Index
}

Viewer shows me that this message was sent out in response:

xap-header
{
v=12
hop=1
uid=FF077400
class=xAP-Audio.Query
source=KCSoft.SliMP3.anya
}
Playlist.Notification
{
status=6
query=index
}

However, I notice that this message is essentially wrong if you have
more than one Slim on your network. At the time I wrote it I only had
the one and never noticed the problem. The latest&amp;greatest
Connector
is much improved in this respect of dealing with multiple Slims.

Anyway, what I've noticed is that if I send a targetted message such
as this:

xap-header
{
v=12
Hop=1
UID=FF123400
Class=xAP-Audio.Query
Source=KCSoft.Send.Anya
Target=KCSoft.SliMP3.Anya:Office
}
Playlist.Query
{
Query=Index
}

Then whilst "playlist index ?" appears on the display, nothing
happens. Is this more like what you're doing?

Fixed in the new build.

>>2. I would like to retrieve the entire contents of the loaded
playlist.
>>Do I iterate on Playlist.Query with an increasing index key or is
there a more
elegant approach.

That's the only way at the moment. That's a good idea though. I'll
post on that one separately.

>>If I iterate, then how do I know the number of indexes in the
playlist?

Send it a message like this:

xap-header
{
v=12
hop=1
uid=FF123400
class=xAP-Audio.Query
source=KCSoft.Send.Anya
}
Playlist.Query
{
query=Tracks
}

You'll get a response such as:

xap-header
{
v=12
hop=1
uid=FF077400
class=xAP-Audio.Query
source=KCSoft.SliMP3.anya
}
Playlist.Notification
{
status=11
query=tracks
}

This is also wrong wrt multiple Slims, but fixed in the newer version.

HTH,
