_MailItem->GetSendOn(&date) throws an exception

[nikolayds via OfficeKB.com]

Hi All,

I am migrating my plugin from 2003 to 2007 Outlook.

A following code is throwing me exception:
<code>
COleVariant covIndex;
covIndex.vt = VT_I4;
covIndex.lVal = 1;
olSelectedItem = olSel->Item(covIndex);

CComQIPtr<Outlook::_MailItem> pMailItem(olSelectedItem);
CComPtr<Outlook::_MailItem> pItemT = pMailItem;

Outlook::OlObjectClass oc = pItemT->GetClass(); //works

DATE dt = 0;
dt = pItemT->SendOn; //Fails with exception


CLSID clsid;
hr = ::CLSIDFromProgID(L"Redemption.SafeMailItem", &clsid);
CComPtr<Redemption::ISafeMailItem> spSafeMailItem;
hr = ::CoCreateInstance(clsid, NULL, CLSCTX_INPROC_SERVER,__uuidof
(ISafeMailItem),(void**)&spSafeMailItem );
hr = spSafeMailItem->put_Item(pItemT);
BSTR name = SysAllocStringLen(L"", 1000);
hr = spSafeMailItem->get_SenderName(&name); //works

return;

</code>
Exception is address violation.

I strongly suspect the issue is with how the params are passed, because all
functions with parameters on Outlook::_MailItem are failing where all others
are OK.

Here is what I have in StdAfx

<code>
#import "C:\Program Files\Common Files\Microsoft Shared\OFFICE12\mso.dll"
rename("RGB", "RGB_") \
rename("DocumentProperties", "DocProps") rename("FindText", "WordFindText") \

rename("PlaySound", "OfficePlaySound")\
rename_namespace("Office")

using namespace Office;
#import "C:\Program Files\Microsoft Office\Office12\MSOUTL.OLB" rename
("CopyFile", "CopyFile_") \
rename("PlaySound", "OutlookPlaySound")\
rename_namespace("Outlook")
using namespace Outlook;
</code>

The code is working just fine in OL 2003

The code is working just fine in OL 2003

Here is the fix: (must use a raw method and queryInterface)

raw_Item(covIndex,&olSelectedItem);

if(FAILED(hr)) continue;

Outlook::_MailItem * pMailItem = NULL;
hr = olSelectedItem->QueryInterface(__uuidof(Outlook::_MailItem),
(void**)&pMailItem);

if(FAILED(hr)) continue;

//CComQIPtr<Outlook::_MailItem> pMailItem(olSelectedItem);
CComPtr<Outlook::_MailItem> pItem = pMailItem;
</code>

After that the methods are working fine in OL 2007.
