I am just starting learning to program add-in in C#. I went through a simple
tutorial that just added a button to the standard toolbar and when clicked
had a popup saying "Hello World". When I go to uninstall the add-in through
Visual Studio 2005 and open Outlook up, the button is still there but doesn't
do anything when clicked. When I try to go into the Advanced Options to see
if it is still registered as a Com Addin, it isn't. The big problem is that
everytime I install the control, I get another button added to the toolbar.
So right now I have 6.
I looked in the registery under both hklm and the one for the current user
but don't see any reference to this add-in.
Below is the code I use to build the control and to then delete it.
Any ideas on how to get rid of all those extra buttons?

public void OnStartupComplete(ref System.Array custom)
{
CommandBars commandBars =
applicationObject.ActiveExplorer().CommandBars;

try
{
this.toolbarButton =
(CommandBarButton)commandBars["Standard"].Controls["AddSave"];
}
catch (System.Exception)
{
this.toolbarButton =
(CommandBarButton)commandBars["Standard"].Controls.Add(1,
System.Reflection.Missing.Value,

System.Reflection.Missing.Value,

System.Reflection.Missing.Value,

System.Reflection.Missing.Value);

this.toolbarButton.Caption = "Add/Save";
this.toolbarButton.Style = MsoButtonStyle.msoButtonCaption;

}
this.toolbarButton.Tag = "AddSave";
this.toolbarButton.OnAction = "!RecordEmail.Connect";
this.toolbarButton.Visible = true;
this.toolbarButton.Click += new
_CommandBarButtonEvents_ClickEventHandler(this.OnT oolbarButtonClick);

}

Below I try 2 ways to delete the item:

public void OnBeginShutdown(ref System.Array custom)
{
CommandBars commandBars =
applicationObject.ActiveExplorer().CommandBars;
try
{

commandBars["Standard"].Controls["AddSave"].Delete(System.Reflection.Missing.Value);
}
catch
{

}
object omissing = System.Reflection.Missing.Value;

this.toolbarButton.Delete(omissing);
this.toolbarButton = null;
}

By the time the shutdown code has fired the event the buttons are out of
scope. You should handle the Explorer.Close event and delete your buttons
there. You also should use the Temporary argument and set it true when you
create the buttons.

To get rid of the existing ones, which will persist forever even without
your addin there since they were added permanently follow these steps.
Right-click on the toolbar and select Customize. Drag the orphaned buttons
off of the toolbar. Exit Customize mode.
