Hi


I have a C# program that scans Outlook items using the Outlook API.
To handle the different types of items I use a kind of switch:


if (oItem is Outlook.DocumentItem) ...
else if (oItem is Outlook.MailItem) ...
else if (oItem is Outlook.AppointmentItem) ...


The thing is I think I may be losing custom forms.


I take it there may be two kinds of custom items:
1. Derived from basic types, for example IPM.Contact.Employee
2. 'All-Custom', for exmample, IPM.AntiVirus


Is there a way to handle these by the Outlook API, or will I have to
resort to using CDO/MAPI?


Thanks

Type #1 would be handled by your existing code.

Type #2 are quite rare these days and could be handled with a last Else block. I'm not sure what object type they'd report. I haven't seen one in years.

Thanks Sue,

I estimate the problem is with #2 items. The question is how can I get
their properties, like subject, creation date etc., and especially
properties I'm not aware of right now.
More to the point: is there a Outlook API equivalent way of
interrogating the item to get field name/value pairs without using MAPI?

ItemProperties, but of course, you'll first need to determine what kind of basic item it is before you can write code for it.

Aye, there's the rub...
There doesn't seem to be a common interface like IMessage in Outlook
that will expose just ItemProperties... Can IDispatch be used to do it
somehow?

I have no idea. I'm just a humble VB/VB.NET programmer.
