How to get mailitem of a new mail in C++

[Kumar]

Hello all,

I am writing a COM Add-In program in MSVC++ to move spam messages to
spam folder. The program has to check message body for specific words
and move it to folder when the new mail arrives in outlook. My problem
is how to get mailitem of new message in OnNewMail method when it
arrives. My code sample is as following.


_ATL_FUNC_INFO OnNewMailInfo = {CC_STDCALL, VT_EMPTY, 0 };
void __stdcall OnNewMail( );

BEGIN_SINK_MAP(CApplication)
SINK_ENTRY_INFO(1, __uuidof(Outlook::ApplicationEvents), 0xf003,
OnNewMail, &OnNewMailInfo)
END_SINK_MAP()

void __stdcall CApplication::OnNewMail( )
{
//
// get mail item here
// check mail body for specific words
// move it to spam folder
//
}


Please help.

Thank You,
Kumar

In case of Outlook 2003 you can use NewMailEx event which passes a list of
entry ids to the event handler, otherwise you can use
MAPIFolder.Items.ItemAdd event instead (where MAPIFolder points to the
Inbox)

Hi Dmitry,


In that case, how do I hook my function to the Outlook events?
I have created an application pointer _ApplicationPtr, which I thought was the event source. But when I use __hook() function, it told me that my class must be a coclass. This is how I inilitialize my Outlook COM:

COutlookAutomation::OutlookAutomation()

{

try

{

HRESULT hr;

hr = p_OutlookApplication.CreateInstance("Outlook.Application");

if (FAILED(hr))

{

MessageBox(NULL, L"Outlook instance failed to load.", L"ERROR", MB_OK);

return;

}

p_Namespace = p_OutlookApplication->GetNamespace(L"MAPI");

if (p_Namespace == 0x00000000)

{

MessageBox(NULL, L"Failed to gain Outlook namespace.", L"ERROR", MB_OK);

return;

}

__hook(&ApplicationEvents_11::NewMailEx, p_OutlookApplication, &COutlookAutomation::TestFunction);
}
catch (_com_error e)

{

MessageBox(NULL, e.Description(), L"ERROR", MB_OK);

return;
}
}
I used CoInitializeEx instead of CoClass.

Will you be able to advice me what went wrong here? Or anybody?

Thanks
