IDShowPlugin interface (qnetwork.h)

  • Article

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The IDShowPlugin interface enables the Windows Media Source filter to communicate with the Windows Media Player 6.4 Plug-in for Netscape Navigator. If Windows Media Player 6.4 is hosted in the Netscape Navigator browser, the Windows Media Source filter uses this interface to retrieve the URL and the User-Agent heading. This interface is not used when the player is hosted as an ActiveX control in Microsoft Internet Explorer.

Applications cannot access this interface. It is documented here for completeness, because it is defined in the header file Qnetwork.h.

Inheritance

The IDShowPlugin interface inherits from the IUnknown interface. IDShowPlugin also has these types of members:

Methods

The IDShowPlugin interface has these methods.

 
IDShowPlugin::get_URL

The get_URL method retrieves the URL of the current web page.
IDShowPlugin::get_UserAgent

The get_UserAgent method retrieves the User-Agent field from the HTTP header.

Remarks

To define the interface identifier, include the header file Initguid.h before Qnetwork.h, but after Dshow.h and other header files:

#include <dshow.h>
#include <initguid.h>
#include <qnetwork.h>
Note  Make sure that Initguid.h is included only once in your project. Otherwise, you will receive linker errors for duplicate GUID values.
