HRESULT ManipulationStarted(
[in] FLOAT x,
[in] FLOAT y
);
Parameter
x [in]
The origin x-coordinate in user-defined coordinates.y [in]
The origin y-coordinate in user-defined coordinates.

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
Hinweise
Manipulation events are generated for both the IInertiaProcessor and IManipulationProcessor interfaces. If you are using the values from the TOUCHINPUT structure in calls to ProcessDown, the coordinates will be in hundredths of a pixel.

HRESULT STDMETHODCALLTYPE CManipulationEventSink::ManipulationStarted(
/* [in] */ FLOAT x,
/* [in] */ FLOAT y)
{
m_cStartedEventCount ++;
// place your code handler here to do any operations based on the manipulation
