Hey all,
Just a quick question. I'm developing an Interface plugin, kind of like the Web Remote, but in Visual Basic. It accepts TCP/IP connections, and dumps "playing now" and "playing soon" stuff over them. A few questions:
- Is there any way for an interface plugin to be notified when the track changes? At the moment, I have a VB timer control and I just check every second if the now playing track filename has changed.
- The plugin only has its init() called when you click on it under "plugins". Correspondingly, when you click away (to "now playing", for instance) it gets shut down. Any way I can have it start up automatically, and not shut down until media jukebox does?
- Given the answers to the above questions, is an interface plugin the right type to use? None of the others seemed to fit...
Thanks in advance.

As far as I'm aware the timer method is the only way as MJ does not have any other callback mechanism.
When you register your OCX set the PluginMode to 1 ... that will make it resident within MJ.
The interface plugin method is your best bet for what you are trying to do.

Ahh, Rhino... thanks. You're a legend.
Next question. Is there any way, in the automation interfaces for MJ, to access the "Album Artist" field for a the currently playing song, as opposed to the "Track Artist"?
If not, it would probably be nice to have it added...
FWIW, I'm working on a little pop-up sliding "Now playing" window which can sit on all our office machines here, while we listen to MediaJukebox on our central server. I had one for RealJukebox, when we used to use that (ack! phht!), now I'm just modifying it for a DECENT music jukebox program. ;)
Thanks.

AlbumArtist is not in the documentation nor in the .tlb file but I would expect it to be very simple for Matt/Nikolay to add it ... ask them ... they're very helpfull.
That little popup sounds like a neat little app.

I am interested in same thing. How can we access "Album Alrtist field? Or we can't?
A related question. I am not sure if this is the correct forum, but anyway: Will future version of MJ9 read the "Album Artist" field? Now, I just see the "Album Artist (Auto)...

Thanks again Rhino.
I've got my software largely working, but one more question for the VB Plugin Development gurus out there...
When I compile my VB control into an OCX on my machine, and run Media Jukebox, the plugin starts fine. When I copy the .ocx to our main server, regsvr32 it, and run the registry file, it all goes OK, but when I start MediaJukebox, it says that the component "must implement IUnknown", and refuses to start it.
Is there something else I need to do other than regsvr32 the .ocx? I thought that was it... and VB Classes compiled as OCXs implemented IUnknown by default.
I'm probably missing something really obvious, aren't I?
-
You have to make sure that you copy over any components your plugin uses, for example are the VB runtime files installed on that machine?
-
Thanks Rhino,
I think that might have been it.
I used the VB setup-file wizard thing to create an installation .exe, and that seemed to work. Must have been a runtime file.
It's currently working a treat, I'll tidy up the code, make it a bit more non-my-workplace-centric, and release it in the next week or two.
