ActiveX Warning Message
 

Hi All,

We have an Add-In that uses ActiveX controls as part of
its implementation.

When we try to run this on Excel 2002 (XP), we get the
following Yes/No warning:
"This application is about to initialize ActiveX controls
that might be unsafe. If you trust the source of this
file, select OK and the controls will be initialized
using your current workspace settings."

I have two questions:
- Is there a way for the user to set an option, so that
this pop-up will not show, and the ActiveX control will
be properly initialized?
- How do I "sign" the ActiveX to prevent these errors?
I know that there are registry keys that can be set for
using ActiveX controls in Internet Explorer, but those
keys don't seem to prevent this problem.

Thanks,
