CFactoryTemplate.CreateInstance method

  • 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 CreateInstance method calls the object-creation function for the class.

CUnknown* CreateInstance(
   LPUNKNOWN pUnk,
   HRESULT   *phr
);

Parameters

pUnk

phr

Pointer to a variable that receives an HRESULT value indicating the success or failure of the method.
