IMSVidInputDevice::View

This topic applies to Windows XP or later.

The View method configures this input device to view the specified tune request.

Syntax

  HRESULT View(
  
  VARIANT*
  
  v
  
  );

Parameters

  pv

[in]  Specifies the tune request as a VARIANT type.

Return Values

Remarks

Before calling this method, set the device as the active input by calling the IMSVidCtl::put_InputActive method. Unless the application needs to choose a specific input device, however, the IMSVidCtl::View method is recommended instead of the IMSVidInputDevice::View method.
