Hi There,

I'm a total amateur writing a nifty little jukebox for my house, with a few
bits of security in preparation for a party... ;)

As a result I'm trying to use Visual C++ with an Windows Media Player
ActiveX control.... And getting absolutely nowhere... Can anyone shed any
light on the methods I need to use?

Also I can't seem to find out how to query id3 tag data with c++...

Anyone out there who's can help a bewildered newbie??

Cheers

How are you doing it now? Where are you stuck.
Here is what I would do.
Go to your resource editor, and add the ActiveX control that you want. (How
to do this depends on your Development Env). Visual C++ .Net, as far as I
know you have to create a dialog or something, then right click on it and
select insert ActiveX control. Visual C++ 6.0 from anywhere you can go
through the menu Project - Add to Project - Component and Controls.
Then create a member variable to it.
Now if you have inserted Windows Media Player then you should have a file
called mediaplayer.h in your project. Open that to see what methods you have
available.
It should have put_Filename to open the file you want.
and there should be a Play, Pause, and Stop methods.

Is that what you are looking for?

AliR.

I fogot to mention, a few years a go I was using the Media Player ActiveX
control. I can't remember why but it pissed me off a bit. I think it was
the fact that I didn't much control over the size and placement of the
movies that I was playing. Anyway I decided to use the mci calls from the
SDK if you are intrested in that.
