Hello, I want to creating an addin that captures when a {contact, calendar,
task, note} is {created, edited, removed}. I have the following code, to make
it shorter I removed all the code but the related to contact, since all types
will be the same I guess.

AutoSync.h
class ATL_NO_VTABLE AutoSync :
public wxPanel,
public IDispEventSimpleImpl1, AutoSync, &__uuidof(Outlook::ItemsEvents),
public IDispEventSimpleImpl2, AutoSync, &__uuidof(Outlook::ItemsEvents),
public IDispEventSimpleImpl3, AutoSync, &__uuidof(Outlook::ItemsEvents)
{
public:
....
void __stdcall OnItemAdd(IDispatch* Item); /* 0xf001 */
void __stdcall OnItemChange(IDispatch* Item); /* 0xf002 */
void __stdcall OnItemRemove(); /* 0xf003 */

BEGIN_SINK_MAP(AutoSync)
SINK_ENTRY_INFO(1, __uuidof(Outlook::ItemsEvents), 0xf001, OnItemAdd,
&OnItemsAddInfo)
SINK_ENTRY_INFO(2, __uuidof(Outlook::ItemsEvents), 0xf002, OnItemChange,
&OnItemsChangeInfo)
SINK_ENTRY_INFO(3, __uuidof(Outlook::ItemsEvents), 0xf003, OnItemRemove,
&OnItemsRemoveInfo)
END_SINK_MAP()

typedef IDispEventSimpleImpl1, AutoSync, &__uuidof(Outlook::ItemsEvents)
ItemAddEvents;
typedef IDispEventSimpleImpl2, AutoSync, &__uuidof(Outlook::ItemsEvents)
ItemChangeEvents;
typedef IDispEventSimpleImpl3, AutoSync, &__uuidof(Outlook::ItemsEvents)
ItemRemoveEvents;

private:
CComPtrOutlook::_Items m_contacts;
};


AutoSync.cpp
_NameSpacePtr pMAPI = OutlookWorker::GetInstance()-GetNameSpacePtr();


MAPIFolderPtr pContactsFolder = NULL;
HRESULT hr = NULL;

//get folders
if(pMAPI != NULL) {
pMAPI-GetDefaultFolder(olFolderContacts, &pContactsFolder);
}

//get items
if(pContactsFolder != NULL) pContactsFolder-get_Items(&m_contacts);

//dispatch events
if(m_contacts != NULL) {
//HERE COMES THE EXCEPTION
hr =
ItemAddEvents:ispEventAdvise((IDispatch*)m_conta cts,&__uuidof(Outlook::ItemsEvents));
hr =
ItemChangeEvents:ispEventAdvise((IDispatch*)m_co ntacts,&__uuidof(Outlook::ItemsEvents));
hr =
ItemRemoveEvents:ispEventAdvise((IDispatch*)m_co ntacts,&__uuidof(Outlook::ItemsEvents));
}


and this defined somewhere else:
_ATL_FUNC_INFO OnItemsAddInfo = {CC_STDCALL,VT_EMPTY,1,{VT_DISPATCH}};
_ATL_FUNC_INFO OnItemsChangeInfo = {CC_STDCALL,VT_EMPTY,1,{VT_DISPATCH}};
_ATL_FUNC_INFO OnItemsRemoveInfo = {CC_STDCALL,VT_EMPTY,0};

When the instructions:
hr =
ItemAddEvents:ispEventAdvise((IDispatch*)m_conta cts,&__uuidof(Outlook::ItemsEvents));
hr =
ItemChangeEvents:ispEventAdvise((IDispatch*)m_co ntacts,&__uuidof(Outlook::ItemsEvents));
hr =
ItemRemoveEvents:ispEventAdvise((IDispatch*)m_co ntacts,&__uuidof(Outlook::ItemsEvents));

are executed, an excetion comes in atlbase.inl' when executes method 'Advise':

ATLINLINE ATLAPI AtlAdvise(IUnknown* pUnkCP, IUnknown* pUnk, const IID& iid,
LPDWORD pdw)
{
if(pUnkCP == NULL)
return E_INVALIDARG;

CComPtrIConnectionPointContainer pCPC;
CComPtrIConnectionPoint pCP;
HRESULT hRes = pUnkCP-QueryInterface(__uuidof(IConnectionPointContainer ),
(void**)&pCPC);
if (SUCCEEDED(hRes))
hRes = pCPC-FindConnectionPoint(iid, &pCP);
if (SUCCEEDED(hRes))
//HERE GIVES EXCEPTION
//Unhandled exception at 0x2fe913e3 in OUTLOOK.EXE: 0xC0000005:
//Access violation reading location 0xcdcdcdcd.
hRes = pCP-Advise(pUnk, pdw);
return hRes;
}

Any idea or suggestion here? Thank you.
