ItemAdd in Deleted Items event doesnt fire after a while

[lin.en.shu]

I'm having this problem where i can't find a solution on my own and
neither can i find and posted solution around the web or forums. The
scenario is this : In order to trace the deleted items, i had added an
ItemAdd event on the deleted items folder to handle the entryid of the
deleted items. Well, it works in the beginning, but somehow i observed
this, after a while, specifically after i deleted a few of them and
after that added a few of them, it no longer handle the ItemAdd of the
deleted items folder. This is strange, and i need urgent help. Thanks.

This is an indication that you are not storing the Items collection in a
variable that stays referenced. As soon as the GC kicks in, the intermediate
variable is released and you no longer received events.

hmm..great. But frankly, I must first apologize because I'm a starter,
and I don't really understand by what you mean of storing the items
collection in a variable that stays referenced. On top of that, how do
I implement that? Please tolerate my incompetencies. Thank you very
much. I deeply appreciate your technical advice.

You probably have something like

MAPIFolder.Items.ItemAdd += new ...

but it must be

m_Items = MAPIFolder.Items; //must be a class rather than a local variable
m_Items.ItemAdd += new ...

I think I did the right one on this. I declare it as a class like how u
put it

myFolders = MAPIFolder....
myItems = myFolders.Items;
myItems.ItemAdd += new ...

but i still face the problem. Any other idea how to solve this?

myItems.ItemRemove += new
Microsoft.Office.Interop.Outlook.ItemsEvents_ItemRemoveEventHandler(myItems_ItemRemove);
myDItems.ItemAdd += new
Microsoft.Office.Interop.Outlook.ItemsEvents_ItemAddEventHandler(myDItems_ItemAdd);
}
catch (System.Exception ex)
{
MessageBox.Show(ex.Message);
}
}

Are you sure you never set myDItems to null?

Nope. I did not set any null at anywhere of the whole code.

You might want to create a small sample add-in that does nothing but monitor
ItemAdd event for the Deleted Item folder and post its source in this
newsgroup (if the problem still manifests itself).

The problem is solved

private void myDItems_ItemAdd(object Item)
{
//myDItems = myDFolder.Items; //previously my friend told me to add
this line to refresh the folder. but after commenting it out it fixed
the problem.
AppointmentItem item = (AppointmentItem)Item;
//blah blah
}
