Newbie Redemption ISafeMailItemPtr question

[Gabriel]

Hi, back with another probably trivial question. I want to use Redemption to
access the headers of a message in my ATL/COM add-in. I thought that to set
my ISafeMailItemPtr object I just need to do this:

CComPtr<IDispatch> dispItem;

hr = spSelection->Item(nItem,&dispItem);




Redemption::ISafeMailItemPtr redMailPtr;

redMailPtr->put_Item(dispItem);

However Outlook (2003) crashes with an "abnormal program termination" error.
I know dispItem is getting set correctly as I'm using it elsewhere in that
method without issue. Is there something obvious I'm missing here?

Much obliged as always,

Which line of your code causes the crash?

Hi Dmitry,

"redMailPtr->put_Item(dispItem)" causes the crash. I can comment that line
out and the method runs fine. (I'm not actually doing anything with the
object yet.) Just to make sure I didn't botch this up, to use Redemption I'm
just putting this in my StdAfx.h file, mimicking the import lines for the
Outlook/Office object models:

#import "C:\Program Files\Redemption\Redemption.dll" rename_namespace(
"Redemption" ), named_guids

using namespace Redemption;

Is this correct? Let me know if you need more information. Thanks again for
your assistance.

How do you create and initialize redMailPtr?

Hi again Dmitry,

I thought that's what

Redemption::ISafeMailItemPtr redMailPtr;
redMailPtr->put_Item(dispItem);

did, creating a ISafeMailItemPtr object and passing an item to it. Should I
be creating an ISafeMailItem instead of Ptr?

Thanks again,

Of course. You simply declare a variable.
Have you tried redMailPtr.CreateInstance()?

Hi Dmitry,

That sorted me out. This is what I ended up doing:

CComVariant headers;

headers.vt = VT_BSTR;



Redemption::ISafeMailItemPtr redMailPtr;

redMailPtr.CreateInstance(__uuidof(Redemption::SafeMailItem));

redMailPtr->put_Item(dispItem);

redMailPtr->get_Fields(0x7D001E, &headers);

One more newbie question just out of curiosity, why is it
"__uuidof(Redemption::SafeMailItem)" rather than
"__uuidof(Redemption::ISafeMailItem)"?

Thanks again for all your help!
