);

Examples

The following C++ example implements an IStylusPlugin::Error Method method that outputs a message and error code to the debug window using The TRACE Macro.

STDMETHODIMP CPacketModifier::Error( 
            /* [in] */ IRealTimeStylus *piRtsSrc,
            /* [in] */ IStylusPlugin *piPlugin,
            /* [in] */ RealTimeStylusDataInterest dataInterest,
            /* [in] */ HRESULT hrErrorCode,
            /* [out][in] */ LONG_PTR *lptrKey)
{
	CString strError;
	strError.Format(L"An error occurred. Error code: %d", hrErrorCode);
	TRACE(strError);
	return S_OK;
}
