Outlook Addin using COM and C++

[Sukhvinder Lamba via OfficeKB.com]

I'm writing an Outlook Addin. The expected functionality of Addin is such
that it adds a toolbar and button to my Outlook 2003. On clicking that
button it pops up a dialog, say Dialog1.
Dialog1 has an Text field and a submit button. I add some text to that text
fiels and on clicking of submit button, i expect new mail to be created and
the text in the text filed be added to the mail as message and that mail be
send to any pre-defined user.
I used the following code, but it throws access violation and causes
Outlook to crash.

CComPtr <Outlook::_MailItemPtr> mail;

m_spApp->CreateItem(olMailItem, (IDispatch**) &mail);

(*mail)->put_Subject( showFCNDialog.m_strSubject);
(*mail)->put_Body(showFCNDialog.m_strMessage);
(*mail)->put_To(showFCNDialog.m_strRecipient);

(*mail)->Send();

Can someone suggest whats wrong here.

Which line causes the crash?
Why do you need the (*) cast? Wouldn't
mail->put_Subject(...)
etc work?
