Hi,
Is there any way to get a pointer to "IWMPCore
Interface" without using any plugins(using VC++)? Any
sample code would be more helpful.

Thanks and Regards,
John

CComPtr <IWMPCore> spWMPCore;
HRESULT hr = ::CoCreateInstance(__uuidof(WindowsMediaPlayer),
NULL,

CLSCTX_INPROC_SERVER,
__uuidof(spWMPCore),
(void **)spWMPCore);
if (FAILED(hr) || spWMPCore == NULL)
{
return FALSE;
}

If you need other interface, you can continue, such as

CComPtr<IWMPPlayer> &spPlayer;
hr = spWMPCore->QueryInterface(__uuidof(IWMPPlayer)
(void **)&spPlayer);

if (FAILED(hr) || spWMPCore == NULL)
{
return FALSE;
}

Not to forget include "wmp.h", I am not sure these are you need, good luck!

You shouldn't do that. IWMPCore is the core interface for the Player
application. If you're using the COM object, you should use IWMPPlayer.

Hi Jim,

Thanks for your advice!
Could you kindly give more details about this, what is the issue if directly
to use interface IWMPCore? I can not find the reason in the WMPSDK help doc.

Regards,
Zhiquan

It really depends on what you're trying to do. If you're embedding the
ActiveX control, you can get the IWMPCore methods off IWMPPlayer because
IWMPPlayer inherits from IWMPCore, so you shouldn't need to get Core
directly.

If you're just using the COM object without a UI, then you should be fine
just using IWMPCore the way the code below shows, but then it is problematic
to QI for IWMPPlayer because it has methods like uiMode that apply only to
the UI. So those methods are out of context and you shouldn't call them in
that circumstance.

Hopefully that's clearer than my admittedly vague posting below.
