PaulSinnema :
Hi ChriZ,

Thanks for the templates. After some struggling got it to work and looks OK. Something is missing though. In the Wiki for VB and C++ a desription can be found on how to create code that reacts to events fired by MC. I can't find anything on how to do that in C#. Got a clue?

Paul.

Hi Paul.
The templates were made around about this time last year,
when MC events were still being developed for the SDK.

The .NET templates use a wrapper to allow them to interact
with the MFC DLL.

As a result the wrapper is still 'wrapping' an older DLL,
so there is no events visible.

It's high on my list of things to get updated. However my time's
really quite fragmented at the moment, so I don't see this
happening within the next week.

If you want something quicker than that, there maybe
some useful information in my top post, where I converted
the VB6 Busy box example to .NET

It's a while since I've looked at it however, and it's
possible I ended up using a different technique for the templates.

I think John Gately also had a go at creating a VB.NET plugin
with events and got them to work.

Not me... sorry...

My mistake, it was PollyQ replying to one of Johns posts,
which wasn't actually related to events what so ever...

In that case I'm not sure anyones actually gone there yet.

[Mr ChriZ]

Hang about... this is much easier than I thought.
I'm over complicating it.

All you need to do is remove the reference to MediaJukebox.
Then add a reference to Media Center 12.tlb
which is in the Media Center folder.

After this you will need to change some (but not all)
references to MediaCenter and MC instead of MJ.

ChriZ,

Thanks for the replies guys. Can see you're very active here. I'll also try your suggestion to change to MC12. Until now had MC11 installed on my development computer. I'll have to change that to MC12 first.

Paul.

ChriZ,

Got it working.

ChriZ,

Now I find out that MC does not send events when the Equalizer is activated or changed and that is exactly what is needed.

Paul.

[PaulSinnema]

ChriZ,

There are some more issues I can not solve with the EventHandler. They are:
- Volume changes
- Mute changes
- DSP changes

In fact I would like to get events on all changes MC makes so I can react.

Paul.

[Mr ChriZ]

Hi Paul, glad you're getting somewhere.
I've not tried playing around with Events at all,
I'll take a look at them at some point over the next week.

I've just got back from the Lake District after a fairly awesome walk
up Helvelyn, across Striding Edge.  Won't be back at my dev machine
for a couple of days still though.

If there's a definite issue with them though, you made need to point them
out to JRiver, who may sort it out in a later build.

[PaulSinnema]

Hi ChriZ,

Events are far from complete. I've been thinking. Maybe I should subclass my window in MC to get the Windows events to my plugin. That way I can react to skin changes.

So you've been walking your butt off huh... Well we've been cycling these last couple of days. We live in Switzerland and I can tell you it's beautifull out here. Enjoyed every minute of it.

See jah, Paul.
