I am very new to this product so forgive me if this is something obvious.

I have created a Plug-in built a very simple form and have onInitialize have the following: 
ADXOlForm1Item = new ADXOlFormsCollectionItem();
            ADXOlForm1Item.ExplorerLayout = ADXOlExplorerLayout.RightReadingPane;
            ADXOlForm1Item.ExplorerItemTypes = ADXOlExplorerItemTypes.olAppointmentItem;
            ADXOlForm1Item.InspectorLayout = ADXOlInspectorLayout.RightSubpane;
            ADXOlForm1Item.InspectorItemTypes = ADXOlInspectorItemTypes.olAppointment
                | ADXOlInspectorItemTypes.olMeetingRequest | ADXOlInspectorItemTypes.olMeetingResponsePositive;
            ADXOlForm1Item.AlwaysShowHeader = true;
            ADXOlForm1Item.UseOfficeThemeForBackground = true;
            ADXOlForm1Item.FormClassName = typeof(ADXOlForm1).FullName;


The form shows up where it is suppose to show.
In the thisaddin.cs I have the following code lifted directly from the example, it also uses the outlookhelper.cs from the example project. 

private void ThisAddIn_Startup(object sender, System.EventArgs e)
        {

            #region Add-in Express Regions generated code - do not modify

            this.FormsManager = AddinExpress.OL.ADXOlFormsManager.CurrentInstance;
            this.FormsManager.OnInitialize +=
                new AddinExpress.OL.ADXOlFormsManager.OnComponentInitialize_EventHandler(this.FormsManager_OnInitialize);
            this.FormsManager.Initialize(this);

            #endregion

            _explorersManager = new OutlookHelper.ExplorersHelper(this.Application.Explorers);
            _explorersManager.SelectionChange += OnSelectionChange;
        }
 private OutlookHelper.ExplorersHelper _explorersManager = null;

        private void OnSelectionChange(OutlookHelper.ExplorerHelper explorerHelp)
        {
            Debug.WriteLine("DoSelectionChange");
            Outlook.Selection selection = explorerHelp.Explorer.Selection;
            try
            {
                if (selection.Count > 0)
                {
                    Debug.WriteLine("DoSelectionChange > 0");
                }
            }
            finally
            {
                if (selection != null)
                {
                    Marshal.ReleaseComObject(selection);
                    selection = null;
                }
            }
        }


When i change items in the explorer window, the event isn't fired.
Thanks for any help.

Hi Stephen,

Where did you get the ExplorersHelper class? Does it come from Add-in Express?

Please note that you develop a VSTO based add-in project and the issue relates to the Outlook Object Model. The http://www.add-in-express.com/support/policies.php section of our web site states the following:

Please note that we do not provide support for issues and questions related to the Office object model for the Add-in Express Regions for Microsoft Outlook and VSTO and Security Manager for Outlook products.

Eugene, I got it from the sample project which comes with add-in Express.

Hi Stephen,

Thank you for pointing out the sample add-in you are referring to. I have just tested it on my PC with Outlook 2010 x64 and didn't notice anything strange on my road. The SelectionChange event is thrown and handled like a charm.

It looks like you modified the sample add-in project. I see the following code in the ThisAddIn_Startup sub: 

explorersManager = new OutlookHelper.ExplorersHelper(this.Application.Explorers);
explorersManager.SelectionChange += new OutlookHelper.ExplorersHelper.SelectionChangeEventHandler(OnSelectionChange);
Outlook.Explorer activeExplorer = this.Application.ActiveExplorer();
if (activeExplorer != null)
{
    explorersManager.DoNewExplorer(activeExplorer);
}


Am I on the right avenue?

seems that i missed the line 

if (activeExplorer != null)   
{   
    explorersManager.DoNewExplorer(activeExplorer);   
}


once that was there, everything else fell into place.
Thanks,
-Stephen
