_MailItem->GetSendOn(&date) throws an exception

[nikolayds]

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

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

<code
HRESULT hr = olSel-
> 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.
