How to search for Unread messages using Domino COM objects

Hi All,

I am a real newbie when it comes to developing for Domino, so please excuse any ignorance.

My environment is .NET and I am using the Domino COM objects. I am using the NotesView class to get access to my Inbox Folder. Is there a way using the selection formula to only return unread items?

Any help on this would be necessary.

Thanks in advance.
