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! 
(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… 
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…
