The SetPropertyValue method assigns a property with a time point to a collection.

  [in] double      dblTime,
  [in] PROPVARIANT varValue
);

Parameters

szName [in]: The name of the new property.
dblTime [in]: A time value for a time point to assign to the property. This should be from 0.0 (the start of the effect or transition) to 1.0 (the end of the effect or transition).
varValue [in]: The value to assign to the property at time dblTime.

Return value

The method returns an HRESULT of S_OK for success, or a standard COM error code for failure.
