Catch an event when/before an Item was deleted

Question

Hello,

i tried to ask this question on Stackoverflow - with no results. 

For my Outlook Add-in I want to get an Event when an Appointment was deleted. 

the problem is, when I apply my handler to the Folder.BeforeDeleted event, it just get fired, when the Folder was created some lines before, not when I get the Folder from Office (because it was created a week ago).

Thanks for Your help!

Answer 1

i;m not entirely sure i understand your description, but have you tried http://msdn.microsoft.com/en-us/library/microsoft.office.interop.outlook.mapifolderevents_12_event.beforeitemmove ?

Answer 2

Yes i did!

my code looks like this:

Outlook.MAPIFolder calendarFolder =
        this.Application.GetNamespace("mapi").GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar);

    // get my-Folder (if not found, create it)
    try
    {
        _CalendarMAPIFolder = calendarFolder.Folders["my-Folder"];
    }
    catch
    {
        _CalendarMAPIFolder = calendarFolder.Folders.Add("my-Folder");
    }
    _CalendarItems = _CalendarMAPIFolder.Items;
    _CalendarFolder = _CalendarMAPIFolder as Outlook.MAPIFolderEvents_12_Event;
    if (_CalendarFolder == null)
    {
        MessageBox.Show("can not cast MAPIFolder to Folder");
    }


    _CalendarFolder.BeforeItemMove += new Outlook.MAPIFolderEvents_12_BeforeItemMoveEventHandler(Folder_BeforeItemMove);

the event only fires, if i created ( Folders.Add(...) ) the folder, not when i get ( Folders[..] ) it.

please verify that you have latest patches for your outlook. Also you might look at this: http://support.microsoft.com/kb/971367/en-us

I don't understand this part of your code. It appears that you are attempting to cast a Folder (or MAPIFolder) as a Folder event:

 

    _CalendarFolder = _CalendarMAPIFolder as Outlook.MAPIFolderEvents_12_Event;
    if (_CalendarFolder == null)
    {
        MessageBox.Show("can not cast MAPIFolder to Folder");
    }


    _CalendarFolder.BeforeItemMove += new Outlook.MAPIFolderEvents_12_BeforeItemMoveEventHandler(Folder_BeforeItemMove);

 

_CalendarFolder should be a Folder, not a folder event. And why are you using MAPIFolder at all there, why not just use Folder directly if you are using Outlook 2007 or higher?
