Duplicate Outlook Add-in Control With Every Build

[JRomeo]

The control I've created via VSTO add-in for Outlook 2003 works, but every
time I make a change and build it, I get an additional control on the
toolbar, a duplicate copy. It must be that I'm not cleaning up after myself
in the add-in. How can I prevent this from happening again and remove those
existing dups? Thanks!

Do you create the button as temporary?

I'm not sure. I'm new at this. Here's my .cs code:


using System;
using System.Windows.Forms;
using Microsoft.VisualStudio.Tools.Applications.Runtime;
using Outlook = Microsoft.Office.Interop.Outlook;
using Office = Microsoft.Office.Core;

namespace OutlookConfCallerBtn
{
public partial class ThisAddIn
{
Outlook.Inspectors openInspectors;

private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
//MessageBox.Show("");

openInspectors = this.Application.Inspectors;
openInspectors.NewInspector += new
Outlook.InspectorsEvents_NewInspectorEventHandler(newInspector_Event);

}

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

/// <summary>
/// Shuts the down add in.
/// </summary>
/*private void ShutDownAddIn()
{
_ContactFolder = null;

_Explorer.SelectionChange -= new
Microsoft.Office.Interop.Outlook.ExplorerEvents_10_SelectionChangeEventHandler(_Explorer_SelectionChange);
_Explorer.ExplorerEvents_10_Event_Close -= new
Microsoft.Office.Interop.Outlook.ExplorerEvents_10_CloseEventHandler(_Explorer_ExplorerEvents_10_Event_Close);
_Explorer = null;

openInspectors.NewInspector -= new
Microsoft.Office.Interop.Outlook.InspectorsEvents_NewInspectorEventHandler(_Inspectors_NewInspector);
openInspectors = null;

Btn_ConfRoomSchdlr = null;


}*/

private void newInspector_Event(Outlook.Inspector new_Inspector)
{
// Check what type of inspector we have
Outlook.AppointmentItem item = new_Inspector.CurrentItem as
Outlook.AppointmentItem;

// For appointment items, add a custom control
if (item != null)
{
try
{
// Get the standard toolbar for this inspector
Office.CommandBars cmdBars = new_Inspector.CommandBars;
Office.CommandBar stdBar = cmdBars["standard"];

// Add the control
Office.CommandBarButton Btn_ConfRoomSchdlr =
(Office.CommandBarButton)stdBar.Controls.Add(1, missing, missing, missing,
missing);
Btn_ConfRoomSchdlr.Style =
Office.MsoButtonStyle.msoButtonCaption;
Btn_ConfRoomSchdlr.Caption = "Book A Room";
Btn_ConfRoomSchdlr.Tag = "Book A Room";

// Set the event
Btn_ConfRoomSchdlr.Click += new
Office._CommandBarButtonEvents_ClickEventHandler(OpenConfRoomScheduler);
}

catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

}

private void OpenConfRoomScheduler(Office.CommandBarButton ctrl, ref
bool cancel)
{
// Assemble the Start Time and End Time values and open a URL
Outlook.AppointmentItem item =
this.Application.ActiveInspector().CurrentItem as Outlook.AppointmentItem;
String StartTime =
item.ItemProperties["Start"].Value.ToString();
String EndTime = item.ItemProperties["End"].Value.ToString();
String Subject =
item.ItemProperties["Subject"].Value.ToString();
String ConfSchdURL =
"http://wnetapps/confroom/index.cfm?event=wizard";
ConfSchdURL += "&StartTime=" + StartTime + "&EndTime=" + EndTime
+ "&Subject=" + Subject;
Object objWeb = CreateObject("InternetExplorer.Application");
objWeb.Navigate ConfSchdURL;
//item.GetInspector.ModifiedFormPages("Appointment").
// Set objWeb = CreateObject("InternetExplorer.Application")
// objWeb.Navigate ConfSchdURL;

}

#region VSTO generated code

/// the contents of this method with the code editor.

private void InternalStartup()
{
this.Startup += new System.EventHandler(ThisAddIn_Startup);

}

#endregion

HI JRomeo,

I'm not sure. I'm new at this. Here's my .cs code:
...
// Add the control
Office.CommandBarButton Btn_ConfRoomSchdlr =
(Office.CommandBarButton)stdBar.Controls.Add(1, missing, missing,
missing, missing);

The last param must be True, then you create a temporary button.

Yep, did the trick. Thx.
