Outlook 2007 / Vista

[Tapper]

I am trying to write an application in C# (VS2005) that does something when
a contact is changed. It appears that I am having some sort of threading
issue in that when the event is fired, the handler is off in another thread
from my application. Here's some code that is an example where a listbox
entry should be added when a contact is changed; the event does indeed fire
but the listbox does not get changed.

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using Microsoft.Office.Interop.Outlook;

namespace TestOutlook
{
class OutlookAppClass2
{

private ApplicationClass objOutlook;
private Microsoft.Office.Interop.Outlook.NameSpace nameSpace = null;
private Microsoft.Office.Interop.Outlook.MAPIFolder fldContacts =
null;
private Microsoft.Office.Interop.Outlook.Items contactItems = null;
private System.Windows.Forms.ListBox passedListBox;

internal OutlookAppClass2()
{
}

internal void InitializeOutlook(ref System.Windows.Forms.ListBox
listBox)
{
passedListBox = listBox;
passedListBox.Items.Add("Start of Initalizing Outlook Class -
thread = " + System.Threading.Thread.CurrentThread.Name);
objOutlook = new
Microsoft.Office.Interop.Outlook.ApplicationClass();
nameSpace = objOutlook.GetNamespace("MAPI");
fldContacts =
nameSpace.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderContacts);
contactItems = fldContacts.Items;
contactItems.ItemChange += new
Microsoft.Office.Interop.Outlook.ItemsEvents_ItemChangeEventHandler(contactItems_ItemChange);
passedListBox.Items.Add("End of Initalizing Outlook Class -
thread = " + System.Threading.Thread.CurrentThread.Name);
}

private void contactItems_ItemChange(object thisItem)
{
string threadName = System.Threading.Thread.CurrentThread.Name;
passedListBox.Items.Add("Contact Change Event - thread = " +
System.Threading.Thread.CurrentThread.Name);
}


internal void CloseOutlook()
{
try
{
nameSpace.Logoff();
}
catch (System.Exception ex)
{
passedListBox.Items.Add("NameSpaceLogoff Exception: " +
ex.ToString());
}
if (fldContacts != null)
ReallyClear((object)fldContacts);
if (objOutlook != null)
{
System.Threading.Thread.Sleep(200);
ReallyClear(objOutlook);
}
}


private void ReallyClear(object thisObj)
{
try
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(thisObj);
}
catch (System.Exception ex)
{
passedListBox.Items.Add("ReallyClear Exception: " +
ex.ToString());
}
thisObj = null;
}



}
