Creating calendar entries

Question

Does anybody have some sample code (preferably C++) that shows how to create
an appointment in the calendar?
I am basically using the same code that I use to create email messages,
which executes OK but nothing shows up in
the calendar. Roughly, the code looks like this (with some lines removed
for clarity):
pIGWMsgFolder->get_Messages(&pDIGWMessages);
pDIGWMessages->QueryInterface(IID_IGWMessages, (LPVOID*)&pIGWMessages);
pIGWMessages->Add(vClass, vType, vVersion, &pDIGWMessage); // class set to
GW.MESSAGE.APPOINTMENT
pDIGWMessage->QueryInterface(IID_IGWMessage, (LPVOID*)&pIGWMessage);
pIGWMessage->QueryInterface(IID_IGWAppointment, (LPVOID*)&pIGWAppointment);
pIGWAppointment->put_StartDate(mDate); // mDate set to start date of
appointment
pIGWAppointment->put_OnCalendar(vFlag); // vFlag set to TRUE
pIGWMessage->get_Subject(&pDSubject);
pDSubject->QueryInterface(IID_IGWFormattedText, (LPVOID*)&pSubject);
pSubject->put_PlainText(bstrSubject); // this set to main title of
appointment
pDIGWMessage->Release();
pIGWMessage->Release();
pIGWMessages->Release();
The only thing different about this from my email creation code is not
calling AddExistingMessage, which didn't
seem to make sense here.

Answer 1

I found some sample code in the NDK (the "Appt" application) and have tried
to model that as
much as possible. The good news is that the compiled version of Appt.exe
will create an appointment
on my system. The bad news is, I still cannot get my code to work. The
Send() call produces the
result x8002009. Any idea what this means? I'm assuming some bad or
missing property, but I believe
I have done everything correctly. Type is being set to egwDraft.
Properties being set are
put_FromText, put_Place, put_StartDate, put_EndDate, put_Duration,
put_PlainText (subject) ,
put_PlainText (BodyText).
