The right approach to get a Contact’s last communication (IItem’s PIMPR_SMARTPROP)

Articolo
05/28/2009

I've discussed about the “wrong” approach in a previous post of mine, where I also talked about why using PIMPR_SMARTPROP to retrieve the info about the last way a Windows Mobile-device user communicated with a given contact. Recently 2 MSDN Forums users asked for help about this (“How to get the information of a selected phonecall number?” and “How to read LastNumber in contact”) and therefore I wanted to invest some time for the Community, hoping this may help others as well! smile_shades (and also to play with POOM, since managed APIs wrapped so many properties making POOM _quite_ obsolete…)

Before spreading the code, let me state a thing: the SmartProp property is not set for a contact until the first time the user
explicitly changes the default contact method, or it is otherwise explicitly set by an application. I noticed this when coding this sample, and later I understood that this is the expected behavior.

Ehy, remember that this is not production code: this is for testing\didactic purposes only… indeed the code is simply meant to dump out to a text-file only the First Name, Last Name and the string representing the last way user communicated with the selected contact. The code doesn’t even use the IPOutlookItemCollection::Find to get a specific contact, as this was not the goal here. Yet, I think it was worth sharing as it is, so that who wants can customize it… smile_regular enjoy!!

NOTES:

PIMPR_SMARTPROP is a property of the IItem, not of the IContact: that’s why for example the old POOM NETCF sample code didn’t contain it. So what we need is to retrieve the collection of Contacts and handle them as IItem.
Once you have all the contacts as a collection (IPOutlookItemCollection), you can’t directly retrieve each item – even if IItem implements IDispatch, the right way is the one for example mentioned by my colleague Xiaoyun Li here, i.e. invoke IPOutlookItemCollection::Item by passing a IContact as IDispatch, then call IContact::get_Oid to retrieve the unique OID and finally use this with IPOutlookApp2::GetItemFromOidEx (see function DumpOutToText below).
At this point you have an IItem object and can query its properties in the usual old way, considering that PIMPR_SMARTPROP will return the property id (e.g. PIMPR_MOBILE_TELEPHONE_NUMBER, PIMPR_SMS, etc); all the propIDs that can be returned as smart prop are listed in the documentation here.
For each returned property, remember to check if it was really found ( .wFlags != CEDB_PROPNOTFOUND) and if it’s of the expected data type ( .propid == CEVT_LPWSTR).

If you know of any smarter way I’ll be more than welcome on continuing this saga about PIMPR_SMARTPROP… smile_teeth
