Modifies a value that indicates whether an object or control has interest in a specified event.

Syntax

HRESULT SetEventInterest(
  [in] InkCollectorEventInterest EventId,
  [in] VARIANT_BOOL              Listen
);

Parameters

[in] EventId

The event to be listened for.

[in] Listen

VARIANT_TRUE to indicate that the event is being used; VARIANT_FALSE if it is being ignored.

Return value

This method can return one of these values.

Return code	Description
S_OK	Success.
E_POINTER	A parameter contained an invalid pointer.
E_INVALIDARG	Invalid event interest.
E_INK_EXCEPTION	An exception occurred during processing.

Remarks

All ink collector events can be toggled by using this method. Most of these events are turned off by default for performance reasons. The only events that are on by default are Stroke, CursorInRange, and CursorOutOfRange.

Use the NewPackets, NewInAirPackets and CursorDown events carefully, in particular because they may have an adverse effect on ink performance if too much code is executed in the event handlers.
