register event

[ethanChou]

i write activex control by C#，now want to use fb to wrapper this Activex Control。Havea a few problems:
The Completed event is not registered.

_ATL_FUNC_INFO efiCompleted = {CC_STDCALL, VT_EMPTY, 1, {VT_BSTR}};

BEGIN_SINK_MAP(axWrapperAxWin)
SINK_ENTRY_INFO(1, __uuidof(AXCTLEVTINTF), 0x00000001, onCompleted, &efiCompleted)
//SINK_ENTRY_INFO(1, __uuidof(AXCTLEVTINTF), DISPID_KEYPRESS, onKeyPress, &efiKeyPress)
END_SINK_MAP()

// Declare the ActiveX control event handler functions
void __stdcall onCompleted(CComBSTR& val);
