event sink for OkKeyDown does not fire?

[schuetz]

Hi all,

I'd like to implement an event sink to handle when the user scrolls up/down
using the cursor up/donw key. I implemented an event sink for OnKeyUp ,
OnKeyDown and OnMouseDown and registered it with the web browser control. For
some reason only the OnMouseDown event fires, when I click in the html doc,
but when I use the cursor up or down keys my event sink does not get called.

Any idea, what I'm doing wrong?

Thanks,
Thomas

code below:

header:

class CDHTMLEventSink : public CCmdTarget
{
DECLARE_DYNCREATE(CDHTMLEventSink)

public:
CDHTMLEventSink();
virtual ~CDHTMLEventSink();
virtual void OnFinalRelease();
STDMETHOD(Invoke)(DISPID dispIdMember, REFIID, LCID, WORD, DISPPARAMS*
pDisp, VARIANT* test, EXCEPINFO *, UINT *);
void OnKeyDown( IHTMLEventObj *pEvtObj );
void OnKeyUp( IHTMLEventObj *pEvtObj );
void OnMouseDown( IHTMLEventObj *pEvtObj );

protected:
DECLARE_MESSAGE_MAP()
DECLARE_DISPATCH_MAP()
DECLARE_INTERFACE_MAP()
};

cpp:

BEGIN_DISPATCH_MAP( CDHTMLEventSink, CCmdTarget )
DISP_FUNCTION_ID( CDHTMLEventSink, "HTMLELEMENTEVENTS2_ONKEYDOWN",
DISPID_HTMLELEMENTEVENTS2_ONKEYDOWN, OnKeyDown, VT_EMPTY, VTS_DISPATCH )
DISP_FUNCTION_ID( CDHTMLEventSink, "HTMLELEMENTEVENTS2_ONMOUSEDOWN",
DISPID_HTMLELEMENTEVENTS2_ONMOUSEDOWN, OnMouseDown, VT_EMPTY, VTS_DISPATCH )
END_DISPATCH_MAP()

void CDHTMLEventSink::OnKeyDown(IHTMLEventObj * /*pEvtObj*/ )
{
OutputDebugString( L"CDHTMLEventSink::OnKeyDown\n" );
}

void CDHTMLEventSink::OnMouseDown( IHTMLEventObj * /*pEvtObj */ )
{
OutputDebugString( L"CDHTMLEventSink::OnMouseDown\n" );
}
