FrontPage Com Add-ins help (FP2003 VC++.net 2003)

[Amber Zhao]

I want to develop an COM Add-in for FP2003 which adds a button to FP
toolbar,and pop-up a window when the button is clicked.
Now I've added the button to the FP toolbar, but how to add event handle to
the button?

There's my code about the event handler:
-------------------------------------------------------------------------------------------------------
connect.h:

extern _ATL_FUNC_INFO OnClickButtonInfo;
class ATL_NO_VTABLE CConnect :
......
public IDispEventSimpleImpl <2, CConnect,
&__uuidof(Office::_CommandBarButtonEvents)>
public:
typedef IDispEventSimpleImpl <2, CConnect,
&__uuidof(Office::_CommandBarButtonEvents)> ButtonEvents;
void __stdcall OnClickButton(IDispatch *Ctrl, VARIANT_BOOL *
CancelDefault);

BEGIN_SINK_MAP(CConnect)
SINK_ENTRY_INFO(2, __uuidof(Office::_CommandBarButtonEvents), /*dispid*/
0x01, OnClickButton, &OnClickButtonInfo)
END_SINK_MAP()

------------------------------------------------------------------------------------------------------
connect.cpp:

_ATL_FUNC_INFO OnClickButtonInfo =
{CC_STDCALL,VT_EMPTY,0,{VT_DISPATCH,VT_BYREF | VT_BOOL}};

void __stdcall CConnect::OnClickButton(IDispatch * Ctrl, VARIANT_BOOL *
CancelDefault)
{
USES_CONVERSION;
CComQIPtr<Office::_CommandBarButton> pCommandBarButton(Ctrl);
//the button that raised the event. Do something with this...
MessageBox(NULL, "Clicked Button1", "OnClickButton", MB_OK);
CExampleDlg dlg;
dlg.DoModal(); // pop up the window
}

STDMETHODIMP CConnect::OnConnection(IDispatch *pApplication,
AddInDesignerObjects::ext_ConnectMode ConnectMode, IDispatch *pAddInInst,
SAFEARRAY ** /*custom*/ )
{
/* add button to toolbar code ignored*/
