RSS feed in Outlook

Answers

  • As its name implies, I would expect the NewMailEx event to fire only for new mail. RSS feed items are not mail. You should be able to use the Folder.Items.ItemAdd method to monitor RSS feed folders for new items. What is it that you want to do with these items?

    I don't write C# code, so I can't speak to the best way to check the type and cast.

  • In Outlook 2007? RSS feed items are PostItem with MessageClass = "IPM.Post.Rss" -- not MailItem.

  • Thank you!

    Yes, I'm using Outlook 2007 and VSTO2005SE.

    Is the Application_NewMailEx event the best way to get new RSS items? If so, how can I check what type the

    Application.Session.GetItemFromID(entryId, null)

    returns? What is the best way to check the type and cast it to PostItem? Now I use Outlook.PostItem post = item as Outlook.PostItem and then check to see if this is null. If not, I check if it's a IPM.Post.Rss.

    However, Application_NewMailEx don't seem to fire for new RSS items.

  • Thank you. Setting and Item_Add event handler on the DefaultFolder for RSS Subscriptions don't work, so maybe I have to set it for each subfolder? What do you think?

    What I hope to achieve is to check for new feeds and check them for padcasts attachment. If the feed is a podcast feed and the item contains an attachment I would like to download it and add it to a playlist in Windows Media Player.

    I thought this would be a quite simple project just to learn more about writing addins for Outlook and on the same time something I'd really like to have.

    Thank you so much for your help both here and on Outlookcode.com.

  • Yes, of course you need to set up an event handler for each folder you want to monitor.

    Your project sounds like a great practical application for playing with the new Outlook 2007 features and VSTO 2005 SE.

  • It's actually quite amazing! I've never programmed Outlook before but I managed to get a working prototype of this working in just two hours. (I have programmed alot for Word, Excel and ASP.NET)

    Now I just have to get a nice UI to select where mp3-files should be saved and create playlists in WMP.

    Is it possible to get the actual rss feed from a folder in some way? It would be nice to only hook up event handlers for feeds that really is a podcast feed and make sure that it downloads enclosures automaticly for just these feeds.

  • Sounds like you're having fun!

    I haven't found where Outlook is storing the feed list yet, although I know it's somewhere in the default information store.

    However, each feed folder has a hidden message containing information about the feed, which you can access as a StorageItem object. The MessageClass is IPM.Sharing.Binding.In, and the Subject holds the URL for the feed, so with a little VBA prototyping: 

        Set fld = Application.ActiveExplorer.CurrentFolder

        Set si = fld.GetStorage("IPM.Sharing.Binding.In", _

                                olIdentifyByMessageClass)

        If Not si Is Nothing Then

            MsgBox si.Subject

        End If

    BTW, if you enjoy this kind of digging, get yourself a copy of Outlook Spy or MFCMAPI.exe.

  • Yeah, I'm having great fun. As you saw on my post on Outlook Code I hade to write an addin in VB6 for a client. Going back to VB6 after doing .net since the first beta really sucked. I just had to do something not so 1997 to wash away that awful VB6-smell from my fingers.

    I'll look in to Outlook Spy! Thanks for the tip and all your help!

    Btw. This is probably super simple, but how do I get hold of the currently selected item? (mailitem, postitem or what ever) Is there something like the Selection-property in Word and Excel?

    Depending on what you mean by that, Application.ActiveExplorer.Selection (a collection) or Application.ActiveInspector.CurrentItem.
