excel working with desktop application

[douglas]

I am using Visual Basic.net 2005 desktop application to write data directly
into an excel 2003 spreasheet. I am using the namespace called
'Microsoft.office.interop.excel' tohave the vb.net application access excel
directly.
The code works fine except when Microsoft has a security update. Then the
code does not work after there has been a security update. I believe the code
does not work since the 'Microsoft.office.interop.excel' is a COM object.
Can you tell me if there is any other namespace that I could use that
would not be affected by each security update that Microsoft has?

Thanks!
