About IWMPNodeWindowed (deprecated)
This page documents a feature that may be unavailable in future versions of Windows Media Player and the Windows Media Player SDK.
The IWMPNodeWindowed interface notifies the plug-in about the parent window. IWMPNodeWindowed::SetOwnerWindow provides the plug-in with the window handle of the parent window. The plug-in window must specify this window as its own parent window. Conversely, when a NULL handle is supplied, the plug-in window must specify the desktop as its parent window. The plug-in should always return this value in IWMPNodeWindowed::GetOwnerWindow.
