IWMPEffects2::SetCore method (effects.h)

[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The SetCore method is called by Windows Media Player to provide visualization access to the core Windows Media Player APIs.

Syntax

HRESULT SetCore(
  [in] IWMPCore *pPlayer
);

Parameters

[in] pPlayer

Pointer to an IWMPCore interface.

Return value

This method returns an HRESULT.

Remarks

You can use this method to set or release a pointer to the IWMPCore interface. If pPlayer is NULL, the visualization is being shut down and all stored references to the core should be released.

This method is not called when Windows Media Player instantiates the visualization for the purpose of displaying its property page. This method can therefore be used as an entry point that will only be called when the visualization is enabled and Windows Media Player loads it normally.
