I have a problem related to ContactItem. Save().

I am using VS2005 C# with MSOffice2003 outlook.

I am working on a AddIn for Outlook.

As my Addin load in application start function. I call a function that
register following two events:

// Get object of Contacts folder.
Outlook.MAPIFolder contacts = ns.

GetDefaultFolder(Outlook.OlDefaultFolders.olFolder Contacts);

items = contacts.Items;

items.ItemChange += new
Outlook.ItemsEvents_ItemChangeEventHandler(
this.Items_ItemChange);

items.ItemAdd += new
Outlook.ItemsEvents_ItemAddEventHandler(
this.Items_ItemAdd);

Now, Whenever any new Contact added to Outlook I assigned it a new
UserProperty of unique ID, to save this ID I have to call function

ContactItem.Save()

Without this any change doesn't save/remain in that contact.

As soon as the ContactItem.Save() executes
Sometimes it raises the events:

Outlook.ItemsEvents_ItemChangeEventHandler(CallFun c);

or

ItemsEvents_ItemAddEventHandler(CallFunc);

and this behaviour is not consistent, some time these events
raises continously and soem other day not.

I want to ask:

1. Why this event raises??

ItemChange fires because you're saving changes to an item.

2. If this raises event then why it doesn't consistent??

Maybe your code is running too fast? The underlying architecture doesn't fire the event if more than 16 items are changed at once. Or maybe you don't have items declared at the module level and the garbage collector is releasing it, so your event handlers no longer run.

3. Is their anyway I could skip or unregister this event??

I'm not a C# programmer, but I know it has a syntax for unregistering an event handler.

FYI, there is a newsgroup specifically for general Outlook programming issues "down the hall" at microsoft.public.outlook.program_vba or, via web interface, at http://www.microsoft.com/office/comm....program_v ba
