Hi!

I have an Excel application that I would like to distribute as an
addin, but I am concerned about security. The application is written
in VBA, in XLA format.

I understand that my best option is to convert my XLA to a COM addin
using Microsoft Office XP Developer.

Questions:

1. Is any additional coding involved? I am not familiar with the API
nor with C++. Is the process anything like a straight "compilation"
from VBA or am I hoping for too much?

2. Do I need to buy the entire Developer package, including all the
Office application components that I already own?

3. I understand that Microsoft has replaced the Office Developer
series with Visual Studio Tools. Can I achieve the same result with
VST or would I face compatibility problems? Is working with VST any
easier/ more difficult?

I am worried that what I'm trying to do is a very small subset of the
capabilities of these tools and that I'll end up investing a lot of
time learning tools that I won't be using afterwards, a bit like
trying to get a drink from a fire hose!

Any help will be appreciated. Thanks!!
