Click Event Being Called Twice

[Josh Asbury]

<< I originally posted this in microsoft.public.dotnet.framework.interop,
and then realized that this might be a better landing pad for it. >>

I am really struggling with something that is going on in an Excel menu
add-in that I have written ( Code snippets are below ) using Visual VB.net
2002. If a commandbar has the same caption as another commandbar elsewhere
in the menu structure, it calls both Click events and subsequently inserts
my custom text twice. Using the code below as an example, both DatesText(0)
and CaseDataDates are set to "Arrangement Date ( January 1, 2004 )". If I
choose one of these menu items, my code fires the Click events for both
CommandBarButtons and subsequently inserts my custom text
("%%=$MMP.CaseArrangementDate") twice.

The same thing was happening with DatesText(1) and
CaseDataDatesInsertText(1) until I set DatesText(0) to "Case Birth Date Day
( 01 )". At that point, only the click event for DatesTextMenuItem1 is
fired (as I wish and expect to happen).

Does anyone have any idea why this is happening and what I can do to fix it?
If I execute this code outside of an Add-in/Interop scenario, it works like
a champ. I'm relatively new to the .net world and Windows programming in
general (I'm a Java guy), so please slap me upside the head and show me the
err of my ways.

Thanks!
Josh

I resolved this issue. It turns out that this was occurring because my code
was setting the .Tag value to be the same, and subsequently causing the
Click events for both to fire. This is what I would consider a gotcha.
