Programmatically creating a map from data in Excel
 

Hello,

I am interested in programmatically creating a map from data in Excel. I
have some GIS data on customer site locations that I would like to
periodically generate a map of.

What is the best path?
A) Write a macro (in VBA) in Excel that could generate a map of the circuits.
or
B) Write a stand alone app (my pref for language is C#)

Also, I noticed that DataMap is not in Excel 2003. Is using MapPoint the
preferred product to use for mapping?

Any thoughts?

Thanks,
David
