IMSVidCtl::get_FeaturesActive method (msvidctl.h)

[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]

The get_FeaturesActive method retrieves the features that are currently active.

Syntax

HRESULT get_FeaturesActive(
  [out] IMSVidFeatures **pVal
);

Parameters

[out] pVal

Receives an IMSVidFeatures interface pointer. The caller must release the interface.

Return value

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

If no features are active, the method might return NULL in the pVal parameter. Otherwise, it returns a collection of feature objects. Use the returned IMSVidFeatures pointer to enumerate the collection.

Examples

CComPtr<IMSVidFeatures> pFeatures;
hr = m_pVideoControl->get_FeaturesActive(&pFeatures);
if (SUCCEEDED(hr) && pFeatures)
{
    long c;
    pFs->get_Count(&c);
    /* Enumerate the features */
}
