Removing command bar and button on DLLUnregisterServer

[NickP]

Hi there,

I have a PowerPoint add-in that creates a command bar and button for
PowerPoint. It works great except at current when PowerPoint is closed, my
bar is removed, so the next time PowerPoint is launched the bar is recreated
and is placed floating above the main window.

As far as I am aware, I have to only remove the bar from PowerPoint on
DllUnregisterServer, but unfortunately I am not quite sure how to get a
reference to the required objects at this time. Any ideas?

Thanks loads in advance.

Nick.
