DDE and TCP/IP data exchange

[Service-Team]

Using the host "localhost" and the service "silverjuke", you can also control Silverjuke by DDE on Windows or TCP/IP on Linux.

The supported topics are simelar the the command line options:

open - clear the playlist and open the files given as data; playback is started using the first given file

enqueue - enqueue the files given as data; the currently playing track stays unchanged and existing files are not removed from the queue

play - same as pressing the "play" button

pause - same as pressing the "pause" button

toggle - toggle play/pause

prev - play the previous track, if any

next - play the next track, if any

kiosk - start kiosk mode

raise - bring the Silverjuke main window to the top of all windows

Please also note the which are easier to use in some cases.

[Service-Team]

Silverjuke 1.15beta2 supports a basic that may be controlled with the following additional DDE commands:

addcredit - adds the numer of credits (tracks that may be enqueued) given in data to the credit system

setcredit - sets the number of available credits to the number given in data

These options only work if "Settings/Kiosk mode/Credit system/Credits may be added by external programs" is enabled.

[Service-Team]

The following commands will be introduced in Silverjuke 1.50beta5:

volup - Increase the main volume

voldown - Decrease the main volume

togglevis - Toggle the selected visualizations on and off

[Service-Team]

The following command will be introduced in Silverjuke 2.52beta2:

execute - Execute the script snippet given in data. Instead of giving the script directly, you can also write the script to a file and give the filename as data.

With this DDE command you are able to execute any little script by the command line. For scripting details, please refer to the .

Hello there

you say:

can you say a lillte more about the use of TCP/IP? Since there is no concept like the DDE 'service', I guess I need to specify a port number, and maybe a protocol? Can I just (for instance) telnet to a port and take it from there?

Thanks in anticipation...

Hello jkn,

Silverjuke uses the wxWidgets classes for interprocess communication. Theses classes use DDE on windows and TCP/IP on other operating systems. For further details, please have a look at http://docs.wxwidgets.org/2.6/wx_ipcoverview.html - please note, that you need some programming experiences to use this service. Please also note the which may be easier to use.

NB: To test the DDE part under windows, we found a little "howto" .

Best regards,
Your Silverjuke-Team

Depending on your requirements the following might interest you: I have created a DLL with a remote HTTP interface for SJ, both the client side and the server side.

This system was originally created by me to have a Silverjuke running on a remote machine control. This uses internally a HTTP client from inside one Silverjuke instance, and a HTTP server inside the other. The interface is just HTTP you can test the system with any browser and control SJ from anything able to transmit a HTTP request.

Development on this system has halted due to lack of testers and time, but depending on your wishes it might give you a headstart if you want to do some serious remote controlling. PM me if you think this is something you can use as I do not want release the code into the public yet.

Final warning however: note this plugin is written in a mixture of C and SJ-script...

Bye,
