IWMPEffects2::Create

The Create method is called by Windows Media Player to instantiate a visualization window.

Syntax

Parameters

  hwndParent

[in]  HWND handle to the parent window hosting the visualization window.

Return Values

This method returns an HRESULT.

Remarks

A visualization that implements IWMPEffects2 is rendered in its own window unless it will be displayed in a clipped device context, in which case it is rendered windowless. For a visualization that is rendered windowless, Windows Media Player calls this method with a NULL value for the hwndParent parameter. If your visualization does not support windowless mode (for example, when using Direct 3D), it should return a failure HRESULT value. In this case, your visualization will not be available in skins that clip the display region.

If you create a visualization for Windows Media Player using the Direct3D® component of Microsoft DirectX®, you must set the D3DCREATE_FPU_PRESERVE flag when calling IDirect3D8::CreateDevice. Failure to set this flag for visualizations that use Direct3D may yield unexpected results.

Requirements

Version: Windows Media Player 9 Series or later.

Header: Include effects.h.
