Hi
I am working on outlook addin

I am having following calls which calls when New mail comes and if user sents mail.

void __stdcall OnNewMail();
void __stdcall OnSend(IDispatch * item, bool cancel);

BEGIN_SINK_MAP(CAddin)
SINK_ENTRY_INFO(1,__uuidof(Outlook::ApplicationEvents),/*dispinterface*/0x0000F002,OnSend,&OnSendInfo)
SINK_ENTRY_INFO(2,__uuidof(Outlook::ApplicationEvents),/*dispinterface*/0x0000F003,OnNewMail,&OnNewMailInfo)
END_SINK_MAP()

which works fine.

now i want same ( IDispatch * item ) in case of NewMail notification handler.

if i put as like this:

_ATL_FUNC_INFO OnNewMailInfo = {CC_STDCALL, VT_EMPTY, 0, { VT_DISPATCH | VT_BOOL }};
void __stdcall OnNewMail(IDispatch * item, bool cancel);

i am getting IDispatch NULL pointer also it crashes once it goes out of OnNewMail Function.


Please suggest where i am going wrong.

your revert is welcome.
